Fiberglass instruction from the manufacturer. We glue the painting "cobweb" fiberglass under painting to protect it from cracks. Why do you need a fiberglass spider web

What is fiberglass for painting, not everyone knows: this innovative finishing material appeared on the market relatively recently and is actively gaining popularity due to its valuable properties. Like other types of modern materials, the cobweb glass canvas painting gives previously unavailable advantages in the process of finishing work.

Scope of the material

What it is? Fiberglass is a non-woven fabric obtained by pressing and consisting of the smallest glass fibers. This is a thin translucent material, therefore, in professional jargon, glass canvas painting is often called a cobweb.

Why do you need a glass canvas painting? It guarantees the avoidance of visible damage to walls and ceilings. The appearance of cracks on surfaces covered with plaster and putty is not always associated with the unprofessionalism of the workers who carried out the repairs. Cracking is caused by the physical properties of traditional building materials, which shrink over time when exposed to dry air.

Another reason for cracking is the constant vibration that is common in homes next to a highway or railroad. Due to the appearance of cracks, the decorative coating had to be frequently renewed in the past.

The use of fiberglass allows you to get perfectly flat, durable and not subject to cracking walls and ceilings.

Hypoallergenicity, fire safety, ease of use, durability and the ability to pass water vapor, due to which the decorated surfaces have optimal moisture, determine the more and more frequent use of cobweb for reinforcing walls and ceilings.

Specifications

Painting fiberglass is a light fibrous material obtained from natural raw materials, which is quartz sand.

Fiberglass spider line is supplied in rolls, the length of the canvas is 50 m, the width is 1 m.

The density of fiberglass varies from 25 to 50 g / m 2.

It is better to choose higher density fiberglass for the walls, and less for the ceiling.

The use of the material is possible at temperatures from -40 to + 60 ° C, which makes it suitable for any climatic conditions.

The cobweb is breathable and hygienic: it does not electrify, does not accumulate dust, withstands wet cleaning, and mold and mildew do not form on it. The material does not emit harmful substances into the air and does not support combustion. All this, coupled with resistance to mechanical damage and the ability to quickly apply, gives the cobweb advantages over other types of finishing materials.

Precautionary measures

The cobweb fiberglass on the wall forms a hard wear-resistant coating that can be washed, but it acquires these qualities only in combination with glue. Before talking about being on the walls, you should take care of the precautions.

The material that has not yet been adhered is fragile enough that small particles can enter the respiratory tract. Once on the skin and mucous membranes, glass fibers cause irritation, therefore, when working, be sure to use a respirator, goggles and protective clothing.

It is possible to glue the cobweb only at a certain temperature (from + 15 to + 25 ° C) and an air humidity of no more than 60%. Drafts are unacceptable during the work, it is required to exclude direct sunlight.

How to properly glue glass fiber? It is necessary that the walls are pre-leveled and filled. Before gluing, you need to carefully fill and reinforce the seams between the plates and then make sure that they do not coincide with the boundaries of the glass sheets. The fiberglass mat is glued to the putty only after applying a deep penetration primer, which will avoid excessive consumption of the adhesive.

The technology assumes that the cobweb can only be glued with special compounds that do not contain starch, for example, Bostic, Oscar, Wellton adhesives produced by fiberglass manufacturers. The same compositions

It should be borne in mind that the material has a seamy and smoother front side: it is important not to confuse.

Sticking rules

You need to glue the material as follows:

cut the material into strips, corresponding to the height of the walls with an allowance of up to 10 cm;
according to the instructions, prepare a solution from dry matter - the cooking time should not exceed 15 minutes (the ready-made solution is also sold, but it is much more expensive);
evenly, without gaps, apply glue to the wall or ceiling - with glue you need to cover an area slightly larger than the width of the first canvas;
strictly vertically, pressing with a roller or a flexible plastic spatula, glue the first sheet, - pasting begins from the corner closest to the window, the sheet is close to each other;
apply the next portion of glue and overlap attach the second canvas - so that the paint looks even, the pile on the canvases should be directed in one direction;
with a clerical knife, cut off the excess under the ceiling, above the floor and exactly along the joint (to get even, it is convenient to press a wide spatula to the borders and cut along its edge);
cover the glued canvases on top with glue - you need to stop when the color becomes uniform.

It is important that the room remains closed until the glue is completely dry. Draft can completely destroy the work results, causing the webs to peel off.

How to prepare fiberglass for painting

Masters are often interested in the following questions: is it necessary to prime the fiberglass, and also whether it is necessary to putty the fiberglass and why is it done? It is not required to prime the coating before or to paint, because the walls have already been primed before gluing it. In addition, glue acts as a primer.

The question of whether puttying is necessary has no definite answer. Fiberglass has a beautiful texture, which is sometimes preferable to preserve, but the paint consumption will be very high and at least 4-5 layers will be required. The paint will make the joints noticeable: even if they are made perfectly, their very presence will not at all decorate the room. It is better to putty the fiberglass before painting for another reason: small fibers can get into the air, which is harmful to health, and the putty completely excludes their penetration.

How to putty? There is no special putty for glass fiber, you can use any finishing mixture on a gypsum or polymer base, the main thing is that it is of good quality.

How to putty glass canvas painting? The technology has some features:

by the time the putty is applied, the glue must be completely dry;
if the cover was glued a few days ago, it must be cleaned of dust;
the adjacent surface is protected with masking tape;
putty is applied in two layers at intervals of a day;
the thickness of the first layer should not exceed 2 mm;
the second layer should be as thin and completely overlap the first;
after drying, the putty is sanded with a bar with sandpaper with a grain size of no more than P150.

Fiberglass putty allows you to get a perfectly flat, durable surface.

Glass fiber painting

How to paint fiberglass? If it is decided to paint the fiberglass without prior filling, no priming is required, but its texture will be visible even under many layers of paint. And yet, painted walls or ceilings will look more attractive if they were previously filled; in this case, apply a primer. To paint walls, it is best to choose water-based paints that fit well and are easy to use.

Painting of fiberglass is carried out using the same technology as painting of other materials.

The paint is applied with a roller until there are no areas of uneven tone on the painted surface.

Is it possible on fiberglass? Yes, since this material is not a finishing material. Fiberglass under the wallpaper is a common finish, but before the final surface finish, you need to putty and prime.

Fiberglass is rarely used as a decorative coating, but it is irreplaceable as a reinforcing material. Its use will allow you to achieve a perfectly smooth surface, and cosmetic repairs will not take much longer.

Painting fiberglass, or as it is also called "cobweb", consists of fiberglass threads. In the production of spider webs, the fiberglass is pressed in a manner similar to the process of making ordinary paper. The result is thin and perfectly smooth sheets with a density of 25-50 g / m2. The standard width of the rolls of painting glass sheets is 1 meter. Usually, all rolls of glass canvas painting have a guaranteed length of more than 50 meters. Less commonly, rolls with special winding are produced, for example, painting glass canvas Wellton economy W40-30m, the rolls of which are 30 meters long. After winding, the rolls are supplied with protective end caps ("crowns"), preventing damage to the edges of the webs, with a product label and packed in a transparent shrink film. The product label of Wellton and Oscar glass fabrics contains a number of important information:

special for quick viewing of goods in the interior;
toll-free consumer support phone number 8-800-200-07-03;
information about;
voluntary marking sign, proving the fire safety of the goods;
properties of the product and its characteristics;
(placed on the back of a rectangular product label).

Despite the similarity of the manufacturing process, glass fibers are very different from their paper counterparts:

are not afraid of water, chemicals and mechanical damage;
do not support combustion and do not spread flame over the surface;
do not accumulate static electricity and do not attract dust;
reliably reinforce walls.

But they also have qualities that resemble the properties of paper:

cobweb canvases consist only of natural ingredients;
allow air and steam to pass through;
prevent the formation of fungus and mold on the walls;
do not cause allergies.

Fiberglass does not have a pronounced relief, therefore, you can repaint the fiberglass as much as you like - since there is no relief, there is nothing to fear that it will be lost. The canvases of all fiberglass canvases can vary in color from white to a light yellowish tone. Differences in color are due to the specifics of production and do not affect the quality of the material. Fiberglass cloths of the same article, having differences in color, when glued to the surface, fit together equally well, so there is no need to select rolls of the same color for work.

Why do we need glass canvas painting?

The fact is that the walls in new buildings shrink for several years, and because of this, cracks appear on them. As a result, ordinary paper wallpaper will simply tear, the plaster will crumble. And the "cobweb" will not only withstand all these loads and hide the existing cracks and irregularities, but will also prevent the cracks from growing and protect the walls from the appearance of new ones.

You can glue the "cobweb" on any carefully primed surface, be it concrete, drywall, chipboard, plastic, etc.

In addition to protecting the surface, glass fiber painting is often used as a finishing material for painting. With the help of a painting glass cloth, you can get a decorative surface with a special texture, formed by randomly located finest glass fibers.

It is important to know that on the market you can find a fake glass canvas painting. This is bituminous or roofing fiberglass, which cannot be used in interior decoration. The main difference between real painting glass fiber and bitumen is the diameter of the glass fibers that make up the material. Painting fiberglass consists of fibers with a thickness of only 8-12 microns, while bitumen fiberglass contains coarser and thicker fibers - more than 13 microns. By the type of fiber, glass fiber painting is classified as "A", while bitumen glass fiber is class "B".

To get the perfect repair result, you should refrain from buying bituminous glass fiber.

Well, now everything is ready - you can start painting, or decorate the walls at your discretion!

Nowadays, the industry produces a very wide range of various materials for construction and finishing work, which greatly facilitate the task of craftsmen, and the result obtained is made much better. These materials include the cobweb painting fiberglass, which got its name due to its external resemblance to a real cobweb.

This type of fiberglass appeared on the construction market not so long ago, but it is already in great demand among craftsmen who have already used it in their work at least once. The use of such material allows you to carry out high-quality finishing, quickly get rid of existing problems with the surfaces of the walls and ceiling, and also prevent the emergence of new ones.

What is painting glass canvas

How is fiberglass made

Many homeowners at all stages of work prefer to choose exclusively environmentally friendly materials for finishing their houses and apartments that do not emit toxic substances at all during their operation and, at the same time, are not subject to rapid aging or wear and tear. It is to this group of building materials that any kind of fiberglass can be safely attributed. Due to its absolute harmlessness, its canvases can be used in all rooms without exception, including nurseries, bedrooms and kitchens.

Fiberglass, from which the canvas is formed, is made from a glass melt that goes through the extrusion process, that is, forcing it through special spinning nozzles with holes of different diameters. The result is fibers of varying thicknesses.

Fiberglass "cobweb" is made of very thin fibers. They are so thin that they become visible to the naked eye only after they are combined into canvases.

Unlike the fiberglass from which they are made, the "spider line" is a non-woven material and does not have a clear regular pattern, since its threads are randomly located. The manufacturing process of fiberglass is somewhat similar to the production of paper. The thinnest fiberglass goes to the conveyor, where it is distributed on the surface of the belt, and then undergoes the pressing process under high pressure with a certain temperature regime. A thin, even web with a smooth surface comes out from under the press. It is immediately reeled up into large bobbins, and from them it is distributed into small rolls, packed and sent to a warehouse or store.

The density of the finished compressed fiberglass "spider" can vary in the range from 25 to 50 g / m².

Advantages and disadvantages of fiberglass "cobweb"

This auxiliary finishing material has its advantages and disadvantages, and it must be admitted that there are much more of the former. It is worth mentioning about them first of all.

So, dignity:

Fiberglass sheets do not accumulate static electricity.
The material is waterproof, completely unaffected by a humid environment.
Resistant to mechanical stress.
Completely inert to any chemical reagents used in construction and decoration
The canvas is air and vapor permeable, therefore, mold does not appear on the surface and under the glass canvas canvases.
Fiberglass is absolutely non-corrosive.
The material is hypoallergenic - harmless to people suffering from hypersensitivity to allergens or respiratory diseases.
Fiberglass is completely non-flammable, has a certain fire resistance, is resistant to sudden changes in temperature.
Due to its structure, it perfectly reinforces and levels surfaces.
Quietly withstands several staining cycles.
It is distinguished by its durability, since it is not subject to either chemical or biological degradation.
Does not attract or absorb dirt, odors and dust.
What is very important - the price of the fiberglass "cobweb" belongs to the category of generally available.

The fiberglass also has a few limitations, which you also need to know about when purchasing it for finishing work. These include the following points:

When cutting glass fiber cloths, small particles of fibers can damage the skin of the hands, therefore it is recommended to carry out this process with rubber gloves.
In addition, when cutting the material, it is desirable to protect the respiratory system and eyes.
It is best to work with fiberglass in clothing made of dense fabric, which will cover all exposed areas of the body. In this case, glass splinters, which cause unpleasant itching and inflammation of the skin, can be avoided.

Varieties of fiberglass "cobweb"

This nonwoven building material is divided into three types according to its density, which can be 50, 40 and 25 g / m2.

The thinnest canvas, one square meter of which weighs 25 grams, is most often used for gluing on the surface of ceilings before painting them. Therefore, this type of canvases is usually called the ceiling "cobweb". However, this type of fiberglass, due to its low density, will not be able to hide strong surface irregularities. Therefore, it is used only for relatively flat ceilings.

A canvas with an average density, weighing one square meter in 40 grams, can be called universal. It is widely used for reinforcing and leveling both ceilings and the material is chosen for pasting on surfaces that are planned to be painted in the future. Due to the high strength of this type of fiberglass, it is excellent for the lower part of the walls, which are especially prone to mechanical damage. The glued canvases will reliably protect these areas from chips and scratches. This material is also used to strengthen dilapidated ceiling plaster - it will perfectly bind and level the surface of the ceiling. This type of fiberglass is also suitable for protecting plaster on walls and ceilings in rooms with increased vibration load.
The most durable type of "cobweb" is a material with a density of 50 g / m². It perfectly closes sufficiently deep irregularities and relatively large cracks. A layer of this fiberglass, glued to the wall, is able to withstand a high mechanical load, therefore it becomes the best option for reinforcing walls in workshops, garages or production halls. The cost of this material is higher than that of the first two types. And besides, when purchasing this version of canvases, it must be borne in mind that the consumption of glue for its installation on the surface is significantly increased. In truth, there is no special need to use this type of canvases for the walls of living quarters. A material with a lower density is also well suited for them.

Features of working with fiberglass and the necessary auxiliary materials

In order for the finishing of the walls and ceiling to have an ideal appearance, the surface for it must be prepared. Previously, this process has always been carried out with putty and plaster. However, to get the job done with dignity requires certain skills that most homeowners do not have. Therefore, it was necessary to call a master plasterer, who performed this rather laborious work for a lot of money.

Now, however, small flaws in the walls are quite capable of being eliminated by the homeowner himself, having pasted over the surface with fiberglass "cobweb", since this process does not require any specific knowledge and skills.

This unique material quickly and easily prepares walls and ceilings for finishing. Moreover, it should probably be clarified that canvases can be glued to almost any surface - it can be brick, concrete, chipboard, drywall, metal or wood.

Adhesive for fiberglass

For high-quality gluing of this finishing and preparatory material on the walls, you will need to purchase the "correct" glue and high-quality primer solution, since the strength of the retention of the canvases on the surfaces will depend on them. In addition, it is necessary to observe the time indicated on the packages of the adhesive and the primer, as well as the period between gluing the fiberglass and applying the finishing.

It should be clarified right away that it is not recommended to fix the canvases on a plaster solution, since it will not be able to saturate the structure of the material well enough, therefore the canvas will not be firmly fixed on the surface. Liquid putty is also not suitable as an adhesive, due to the fact that it will not saturate the fiberglass evenly, and in those places where the material is not sufficiently saturated, the "cobweb" may begin to bubble. To avoid these negative points, for gluing the fiberglass, you need to use a glue specially designed for it, which is sold ready-made or dry.

Each type of fiberglass has its own type of glue, so you need to adhere to the recommendations and use the composition that is intended for a specific material. However, on sale you can also find a universal glue that is suitable for all types of fiberglass - "cobwebs", but it must be diluted in certain proportions, since the canvases must be fully saturated with it.

Glue "Oscar" is intended for gluing fiberglass, which have a sufficiently high density, therefore it is often used for gluing fiberglass "cobwebs" with a density of 40 g / m².

Glue "Wellton", sold in dry form, is universal, so that it suits a specific type of fiberglass, it is diluted in certain proportions indicated on the package.

Glue "Kleo" is also universal, and is used not only for gluing all types of glass sheets, but also for non-woven wallpaper. It is produced ready-made and dry.

In addition to these compositions, in the hardware store you can find others designed specifically for glass sheets. All adhesives of this type are environmentally friendly materials and are manufactured according to a specific formula, and their components interact well with fiberglass. In addition, they contain antiseptic agents that counteract the formation of colonies of fungi and mold.

Adhesives intended for fiberglass and fiberglass do not leave marks and stains on the surface. Therefore, if the canvas is already glued to the surface, but it can be seen from its impregnation that the applied adhesive solution is not enough, it is quite permissible to walk over the surface of the material with a wide brush with glue in order to achieve complete uniformity of impregnation.

All technical characteristics of the glue can be found on the packaging, including its consumption per square meter. However, it must be remembered that the consumption of the adhesive solution will also depend on the material of the surface to which the fiberglass will be glued, as well as the quality of its preliminary treatment with a primer composition. The better the surface is prepared, the less glue will be required. In order to be guided by the time in work, it must be said that the period of final drying and setting of adhesives of this type, as a rule, is 48 hours.

The process of gluing painting fiberglass - "cobwebs"

To stick fiberglass on walls or ceilings, you do not need any special professional skills. You just need to know the stages of work and clearly follow the presented technological instructions. Thanks to the decision made to strengthen and level the walls on your own, you can save a decent amount, since repair work is not cheap at all.

Illustration	Brief description of the performed operation
	The first step is to remove the old decorative coating from the walls, if it is wallpaper or plaster, which has begun to spontaneously separate from the wall.
	The cleaned wall must be examined carefully. If wide and deep cracks are found, they must be repaired, as they will contribute to the delamination of the material from the wall. For this, the crack is widened, impregnated with a deep penetration primer and dried, and then filled with a sealant or cement-glue mortar. The surface of the filled cracks must be leveled as much as possible. If rather large projections are found on the wall or ceiling, then they must be knocked down with a hammer or cut off with a grinder with a circle over the stone.
	The next step is to clean the surfaces of dust and dirt - this process can be done with a brush or you can use a vacuum cleaner for it. On the surface, there should be no large particles of cement or other solid matter, such as crumbs of plaster or putty.
	Further, the surfaces must be primed with a deep penetration solution. Such solutions, applied in two, and sometimes in three layers, penetrate into the wall or ceiling to a considerable depth, closing the pores in the structure of the material and contributing to additional waterproofing. In addition, the primer creates a film on the surface that will create high adhesion for the materials applied to it, in this case, the adhesive solution. This type of primer is also able to bond and strengthen weak layers of plaster. The primer should be absorbed into the surface structure and dry well.
	If serious irregularities are found on the wall, then after the primer has dried, you need to try to level them with a ready-made putty, which is applied with a wide spatula. However, this process is performed only as a last resort - usually only glass fiber is enough for high-quality leveling. If the putty was nevertheless applied, then after it dries, the surface must be covered with another layer of primer.
	When the walls are dry from the primer, you can start gluing the glass fiber canvases. The glue is applied to the section of the wall to which the material is to be glued. If the entire wall is pasted over with a "cobweb", then its installation starts from the corner of the room.
	A canvas is applied to the section of the wall surface smeared with glue, and it can be of any size, since the fiberglass fits well, and overlaps, due to the thinness of the material, become almost invisible (however, you can get rid of overlaps altogether - more on that below). The canvas is pressed in the upper part, and then, smoothed according to the "herringbone" principle with a special plastic wallpaper spatula. That is, first, a spatula is carried out with a slight pressure in the center of the sheet, and then, starting from the top, from the middle, they begin to expel the excess glue down and to the sides, as if "drawing" the branches of the Christmas tree. The adhesive composition is absorbed into the fiberglass quickly enough, so there will not be much excess, and it will not take long to drive them out from under the canvas. It will immediately be seen from the material how well it is impregnated with the adhesive, but in order to prevent even the slightest probability of its peeling, it is recommended to walk on top of it with a roller, also moistened with glue.
	If it is necessary to level the ceiling, then it is best to carry out this process with an assistant. If you have to do this work alone, then it will be more convenient to glue the fiberglass in small pieces. For this, a layer of glue is also applied to the surface, and then, starting from the wall, a sheet of leveling material is glued.
	After sticking the first sheet of material, a nearby section of the wall is smeared. The next sheet is applied to it, and it can be glued end-to-end or overlapped, by about 40 mm. If the second option is wiped off, then immediately after gluing the second sheet from its edge, which is on the first sheet, 20 mm is measured. Then a metal ruler or a flat wooden lath is applied vertically to the points found, parallel to the edge of the canvas, and a sharp knife is drawn along it, cutting through both sheets. After that, the cut parts of the canvases are removed, and the edges are pressed against the wall with a spatula. Thus, a perfectly even joint of two sheets is obtained, which must be pressed with a roller dipped in glue.
	If the canvas turned out to be longer than necessary in length, then it is best to cut it off immediately. To make the cut even, the fiberglass is strongly pressed against the wall with a wide spatula, and then it is carried out, like along a ruler, along it with a sharp knife. If necessary, the edges of the web are additionally glued. You can proceed to further work on finishing the walls only after the glue has completely dried - this time is indicated by the manufacturer on the packaging.

When gluing canvases to walls or ceilings, as well as during the period of drying, there should be no drafts in the room. You can also not turn on electric heaters, trying to speed up the drying of the glue, as this can lead to delamination of the material from the wall.

When reinforcing walls or ceilings with fiberglass, it is necessary to make preliminary preparation of the surfaces, which is necessary for this material. Since such a sheathed surface has sheet joints that are somewhat deepened relative to the general level, they must be brought to one plane using a putty. Before applying it, it is recommended to prime and glue the joints with a mesh or special paper tape. The primer will increase the adhesion of the materials, and the putty will be well fixed on the surface, and the reinforcement will not allow cracks to appear with possible movement of the wall (shrinkage, vibration effect, seismic factor, etc.)

Basic rules for the preparation of plasterboard walls for further finishing

The preparation for finishing does not end with the installation of drywall sheets on the walls - there is still another rather difficult and time-consuming stage ahead. - read in a special publication of our portal.

After the putty has dried in the seams of the drywall, the entire surface of the wall is covered with a primer, which must also dry out, forming a film on the surface.

After that, you can start the process of reinforcing drywall with a "cobweb". It is glued in the same way as on a concrete or plastered wall.

Decorative finishing of the wall covered with fiberglass

Fiberglass is painted or coated with other materials only after it has completely dried out. Walls covered with painting glass can be painted without additional coating, or after applying a leveling layer of putty on them.

If the paint is applied directly to the "cobweb", the structural pattern of the canvases will be visible through its layer. In addition, you need to know that a lot of paint will be required, since even a material impregnated with glue absorbs the paint composition well.

If it is planned to get absolutely smooth walls, which are necessary, for example, for gluing thin paper wallpaper, then an equalizing layer of putty is applied to the fiberglass.

For work, a finishing putty is used, which is sealed with water and mixed in strict accordance with the instructions supplied by the manufacturer, and applied to the surface with a wide spatula, starting from the corners of the room. If in order to glue the fiberglass you do not need special skills, then to perfect smoothness it requires a certain skill and experience.

Some novice craftsmen succeed in this process immediately, while others cannot cope with this work in any way. To test your abilities, it is recommended to prepare a small amount of putty mixture and try to apply it to a small, not particularly noticeable section of the wall. If everything works out, then it will be possible to save on the implementation of this stage of the work by doing it yourself.

The putty should be applied in a thin layer of 1.5 ÷ 2 mm, taking care not to leave grooves and stripes on the surface from the edges and corners of the spatula.

After applying the putty, it is necessary to wait for it to dry, after which the surfaces are treated with sandpaper to perfect smoothness. This work can be done by hand using a construction trowel, or you can use a sander (for example, an eccentric or vibrating machine) for leveling, to which the abrasive paper is fixed.

If the putty is applied in two or three layers, then each of them should dry well before applying the next one.

The advantage of painting non-putty glass fiber is that the irregularities in the application of paint on it will be less noticeable, since the structure of the material is able to hide them due to its relief. However, due to the fact that the fiberglass absorbs paint well, it will have to be applied in at least two layers, the second of which is applied 12 hours after the first.

It is more difficult to apply paint evenly on a perfectly smooth surface, since all color differences will be noticeable on it. Therefore, in order for the coloring to be uniform, sometimes it is necessary to apply the coloring composition in two or even three layers.

For painting glass fiber or putty surfaces of living quarters, it is recommended to use water-based paint, applying it with a roller with a fur nozzle, and carefully and accurately tint hard-to-reach areas of the wall and ceiling with a soft brush.

Some craftsmen, in order to bypass the stage of glass fiber putty, after gluing and drying it, apply several layers of densely mixed glue to the reinforced surface, each of which is also dried. The adhesive layer, filling the structural pattern of the surface, makes it smoother, but not perfectly flat. The adhesive layer will also significantly reduce the consumption of the dye composition.

How to choose fiberglass?

To purchase high-quality material that will meet all of the above characteristics, you need to choose products from well-known manufacturers.

On the Russian market of building materials, the products of manufacturers from Glland - Spektrum, Finland - Wellton, and Sweden - Oscar and Samtex gained popularity. Among domestic manufacturers, the technology of glass fiber fabrication, in full compliance with world standards, has been well mastered by the "X Glass" company. It should be noted that almost all companies that produce fiberglass, except for them, produce fiberglass wallpapers, as well as adhesives for them - these products are sold under the general brand of the company. It is advisable to use a canvas and glue of the same brand - they are completely adapted to each other.

In conclusion, I would like to remind you that painting fiberglass “cobweb” is primarily intended for reinforcing walls and ceilings of premises and protecting them from the expansion of small cracks that have appeared, as well as from the appearance of new ones. The second function that this material is designed to perform is leveling surfaces. However, many homeowners also prefer to preserve the structure of fiberglass without covering it with putty and using it as a decorative material. Thus, the "cobweb" acquired a third function.

One cannot but agree that this multifunctional material helps to solve many problems and save funds allocated for finishing the premises. Therefore, for many owners, it can be a real salvation when carrying out any repairs - both cosmetic and major.

And at the end of the publication, traditionally - a video on the topic. This time, a professional finisher will share his experience of gluing a fiberglass “cobweb”.

You can spend a lot of effort and money on finishing materials for an apartment, but in the end, due to improper technology, the result will quickly become unusable. It is especially difficult to manufacture as new buildings shrink and cracks are inevitable in the early years. In this article we will tell you about fiberglass: its application, characteristics, prices, and most importantly - how to stick it with your own hands.

Beginners may confuse the "cobweb" fiberglass painting with fiberglass wallpaper, but in fact they are different things, only they are very similar in appearance. Fiberglass is also composed of strands of fiberglass, but it is produced by pressing rather than on a loom. Fiberglass sheets are thin and translucent. The surface is smooth, but due to their structure, they are prickly.

This material has all the qualities of fiberglass, that is:

resistant to fire, water, chemical and mechanical influences;
does not cause allergies;
consists of environmentally friendly material;
does not accumulate static electricity;
allows air to pass through, so the walls "breathe".

However, despite the listed characteristics, the cobweb has vulnerabilities. If a crack has formed parallel to or near the seam, it will pop out. This often happens when fiberglass is glued to drywall. Therefore, you need to avoid gluing the canvas along the seams of the gypsum board and retreat at least a few centimeters.

Painting fiberglass is sold in rolls of 20 and 50 meters, 1 m wide. Its price depends on the density of the material (20-65 g / sq. M.), The cost varies between 380-800 rubles per 50 sq. M. m. The most optimal cobweb with a dense structure, 45-55 g / sq. m.

Areas of use

Fiberglass "gossamer" is used to reinforce the base before finishing, but not as a topcoat. It is used for plasterboard structures, walls, ceilings. It can be called the most effective remedy in the fight against cracks.

The video will show the technology and features of the use of fiberglass for interior decoration:

Adhesive selection

Special glue for fiberglass is used for fiberglass. Sometimes it comes immediately in the kit. Be sure to observe the proportions indicated on the package when diluting the glue, it should not be liquid. The glue should be taken with a large margin, since the consumption for fiberglass is much higher than for plain wallpaper.

Like any wallpaper, glass canvas painting is very afraid of drafts when it dries. Therefore, in no case open the vents during operation. According to SNiP 3.04.01-87. “Insulation and finishing coatings”, during gluing the wallpaper must be protected from drafts, direct sunlight and constant humidity must be set in the room. The same rules apply when working with many floor coverings.

The walls are prepared, as well as for gluing wallpaper, but small cracks can not be repaired. If the width of the crack allows you to crawl into it with a spatula, you must first treat it with a strong putty (for example, Knauf Uniflot), and then sand the surface. The surface must be level, putty and treated with an appropriate primer.

Getting started gluing

Now let's figure out how to glue the fiberglass on the walls or ceiling. For this, glue is abundantly applied to the surface. At first, it will be enough in the width of one sheet. The glue will quickly be absorbed into the canvas, so you hardly have to expel it from there.

- The canvases can be cut to any length, as it is more convenient for you. For walls, you can cut the full height, and for the ceiling no more than 2 m.

When gluing, it is important to trace the position of the front of the canvas. Usually it is directed towards the inside of the roll. Both sides look almost the same, so check the label for this information.

- Apply the first piece of canvas to the surface and smooth it gradually with your hands so that the edge matches the corner of the room. Then, use a plastic wallpaper spatula to run over it to remove excess air and air bubbles from the inside. This should be done with herringbone movements, from the middle to the edges.

- When the sheet has settled tightly, cut off the excess and saturate the sheet again with glue on top so that it is thoroughly saturated. Then, once again go over the surface with a spatula, rubbing the glue inward. The sheet should be completely saturated and darken slightly with moisture.

- Then we cut off the next sheet. You need to glue with an overlap, on the ceiling it is better to place the canvas along the room.
- We glue the surface with an overlap on the old sheet. In the same way, we glue it, impregnate it and press it. To get an even and invisible seam at the junction of two sheets, take a sharp knife and cut a line through two layers of fiberglass. Additionally, the seam is impregnated with glue. The same technique applies to adjacent sheets. It's okay if the seam turns out to be uneven: the main thing is that it is smooth and invisible after finishing. In place of the corners, the canvas needs to be cut.

When working, it is necessary to observe safety precautions: use gloves, a respirator, a hat, long tucked sleeves. Sharp fiberglass particles can enter the respiratory tract and skin and cause irritation.

After a day, the glue will dry, and you can proceed to further finishing. To make a fiberglass for painting, you need to putty it in at least two layers. This will hide its texture and reduce paint consumption. One layer of putty is enough under the wallpaper.

What if a crack appears?

If a crack does appear, it can be easily fixed. A fiber patch is glued directly on top of the putty so that its width is at least 6 cm wider than the crack.

Then we take a knife, press down hard and make an incision around the perimeter: through a patch, a layer of putty and an old canvas. We remove the layer of putty and glue the patch obtained exactly to the size. Apply several layers of putty on top.
If you want to extend the life of your finish, be sure to use an inexpensive but very useful material like glass fiber. It is especially relevant for repairing cracks in plasterboard ceilings and boxes, which often crack at the seams. If you follow the technology of installation of the structure and add to this the correct reinforcement of the joints, you will forever forget about microcracks.

Fiberglass under the putty is a simple, quick and proven way to give strength to the interior decoration of walls and ceilings, and level them, at the same time making additional reinforcement. The cobweb, as the builders call the fiberglass, is made by pressing and is a translucent sheet, usually rolled into large rolls.

The opinions of experts on the need to align the cobweb differ, some of them believe that gluing the canvas is quite enough, while most builders are convinced that the putty of the fiberglass is extremely necessary.

The latest trend in modern finishing work is the gluing of fiberglass before the final stage of decorative wall decoration. The material gained popularity due to its useful qualities, but not everyone came to a consensus on how to use it and how to cover it after gluing, paint the fiberglass immediately after gluing or pre-apply a protective layer on it.

The need to use fiberglass when working with drywall was dictated by the appearance of cracks in this building material, which mainly appeared at the joints, along the seams. Previously, a serpentine mesh was used, but it turned out that it does not provide sufficient guarantees of strength and does not always prevent the formation of cracks, especially if they appear under the influence of building shrinkage or sudden temperature changes. The trend towards the use of fiberglass appeared in order to avoid such a nuisance.

By itself, the building material breaks easily enough, because it is made of thin fiberglass threads, bonded together with an organic compound. However, on the wall, such a canvas acquires non-analogous reinforcing properties and helps to ensure the integrity of the coating of the finished walls for a long time.

The main advantages of the material

A cobweb or mat, as fiberglass is called in professional slang, has a lot of invaluable properties, which led to its widespread use:

environmentally friendly because it is made of natural materials;
has increased strength and exceptional wear resistance;
practically not subject to temperature and mechanical damage;
does not accumulate static electricity and due to this does not attract dust;
does not cause any allergic reactions in the inhabitants of the home;
possesses extremely fire resistance, does not ignite and is often used for finishing passages that provide evacuation of people in large buildings in case of fire;
in the role of a reinforcing frame, it absorbs the finishing material and gives it exceptional strength;
does not contain any nutrients for fungus and mold, is not subject to their destructive effect.

There is no disagreement about the use of the cobweb in finishing work performed with ultra-modern materials. The main point of controversy is whether it is possible to paint a reinforced surface immediately or is the use of a putty cardinally necessary?

How much is glass fiber putty needed?

People who do not have special knowledge, and especially those who move into a new room, where the interior decoration must be done on their own, often wonder whether it is necessary to putty the already finished fiberglass or it is enough to simply paint it. After cracks appear on the surface of the recently finished walls and ceiling, and tears and bubbles appear on the glued wallpaper, it becomes clear that this was necessary. Especially when, when trying to remove the warped wallpaper, the cobweb will follow them.

If the painting or wallpapering was done directly on the fiberglass, the texture of the fiberglass, and the seams, and joints, which in this version will remain uncovered, will certainly be noticeable. This will give the freshly finished space a not very neat look.

Fiberglass for putty should be purchased quite dense, this will simply further enhance its reinforcing properties. Such material is more expensive than thinner, but this is not the option on which you should look for a way to save money. Re-repairs when the thin web does not fulfill its purpose will be much more expensive than the small difference in price between the denser and denser pressed material.

Choice of materials

Both the putty and the glue for fiberglass must be of the highest quality, each layer must certainly dry, and only after that the next one can be applied. To solve the problem of how to putty, you can purchase two types of material or use a universal ready-made composition. It can be applied at any stage, so as not to think about whether or not I putty with the same composition.

The cobweb, despite its slang name, should be acquired dense enough, while it is necessary to consult with a specialist what density is optimal in order to stick it in specific conditions (private house, apartment in an apartment building, new building, secondary housing).

More glue is used on fiberglass, because this building material is characterized by high absorbency, and its consumption is much higher than that of fiberglass.

Surface preparation

The main stage of gluing glass fiber is a cardinal surface preparation. Glue the fiberglass should only be on the prepared wall and first stock up on the necessary tools and materials.

The main part of the preparatory stage consists in applying a layer of putty on drywall and then filling problem areas with putty. These include joints, chips, mechanical damage, corners and fasteners.

Compliance with technological standards is a rather complicated process, but still it does not constitute much wisdom and even not a construction specialist can carry it out:

It is recommended to clean the places of application before puttingty, especially if other work was carried out in the room before.
It is necessary to putty the wall under the fiberglass with the utmost care, trying to ensure that the embedments do not differ from the bulge in relation to the rest of the wall.
Seams should be filled especially carefully, using a spatula and additional sanding, creating the most even surface.

If the damage or joints required a significant layer, and the putty sticks out strongly, so that this can hardly be corrected by sanding, an additional layer is applied over the entire surface of the wall.
Before you start gluing the fiberglass, it is necessary to finally grind the dried layer of the putty mixture and remove dust and plaster contaminants from the rest of the surface. Experts recommend doing this with a damp sponge and a vacuum cleaner.

The application of a new leveling layer to it, and the quality and safety of the final finishing coating, depends on how smoothly the surface will be finished on which the reinforcing base will be glued.

Gluing fiberglass

For a quick and accurate installation of the fiberglass on the ceiling, mark the roll according to the required length, and cut the pieces in advance. In advance, you need to prepare glue, if, in order to save money, it was purchased not in finished form, but in the form of a concentrate.

When making the composition at home, all instructions provided by the manufacturer must be followed. Wear protective clothing to avoid getting fiberglass particles on your skin, and arm yourself with a glue brush. It allows you to initially apply a thick layer, which is necessary, given that the fiberglass absorbs large quantities of glue.

When everything is prepared in advance, the process moves forward quickly:

The first layer is glued from the corner, the surface is leveled by hand.
Air and excess glue are removed with a smoothing trowel.
If necessary, use a construction knife to remove excess fragments.
The glue is applied to the wall, and after laying the cut fragment - on its surface.
The process is carried out continuously - glued one sheet, followed by a second in the joint, and so on.
The material is trimmed slightly at the inner and outer corners so that the tear line is not uneven.
It is important that the joints of fiberglass and drywall fall in different places, otherwise the seam will certainly crack.

The glued material dries for at least a day in a room where the possibility of drafts has been eliminated. Before leaving the walls to dry, it is imperative to inspect the reinforcing layer for flaws and eliminate them. On the finished wall, every bald spot and bulge will be visible.

Important nuances

If the finish is not done with their own hands, but by craftsmen who are interested in its early completion, they may insist that the surface can already be painted. If you do not putty the fiberglass, then paint on it will have to be applied 5-6 times more, because the fiberglass has a great ability to absorb. For gluing wallpaper, it is all the more necessary to prime the fiberglass and apply a putty layer, because the entire texture of the fiberglass will be clearly visible, and the wallpaper glue will also go unmeasured.
