Concrete screed on OSB plate. Installation of OSB plates - features of laying on a wooden and concrete base. Tools and Materials for Work

The draft floor is quick, efficient and inexpensive - most of the builders and their customers try to achieve this combination. The easiest thing is similar to the floor covering from OSB plates. The laying technology depends on the type of base and additional requirements for the finished floor.

OSB: Composition and characteristics

OSB or OSP is oriented chipboard. In transliteration, OSP is often called OSB, but this is not entirely true, as it contradicts the decoding, but is used everywhere.

Plates are composite from large wood chips and polymeric binders. Forms of several layers located perpendicular to each other. This design ensures the stability of sheets to twisting deformations and makes them resistant to the separation and bundle.

According to the production technology of the OSB, a chipboard with the difference is identical to the difference that the first is used fine-stranded chips to 4 mm thick and up to 25 cm long, and small sawdust is used in the production of the second. The thermosetting resins (carbamide-formaldehyde, melamine, etc.) are added as binders for raw materials. Typical sizes of plates:

height 2440 mm,
width - 1220 mm,
thickness - 6-38 mm

OSB is produced in 4 varieties:

OSB-1 - Thin plates used for the production of packaging, furniture blanks, design of temporary structures, etc.
OSB-2 is standard sheets that can be used in dry ventilated rooms. Application - for internal draft works (flooring, alignment of walls, ceiling, formation of households, etc.).
OSB-3 - moisture-resistant material with a paraffin additive content. It has increased resistance to high humidity, recommended for use both indoors and external finishing works.
Withstands increased humidity and indoors, and outside. When used in such premises as a bathroom, a bath and others, it is recommended to use degrade or floorproofing materials.
OSB-4 - durable plates of high density. This is a material for the formation of supporting structures.

It is uniquely impossible to say which one is better or worse. It all depends on the destination. Alignment of the base under laminate, linoleum, ceramic tiles and other types of finishing materials are carried out by sheets of OSB-3. Their advantages are that they perfectly withstand serious loads (furniture, equipment) even when installing on lags, resistant to temperature and humidity drops are easily processed, and the installation is even inexperienced.

In addition to the above, OSB is a heat insulating material with a small noise-repeating effect. Therefore, so often manufacturers of vinyl and carpet coatings strongly recommend putting onto a concrete floor first a warm substrate from solid wood materials, which closes the finishing finish.

The thickness of the used plates depends on the installation method. For a concrete smooth base with a drop of no more than 2-4 mm for every 2 meters of area, the use of panels 10-12 mm is reasonable. When laying with their own hands, the installation of OSB with a cross section from 18 mm and more is substantiated on the lags. Specialists recommend putting sheets of 10-12 mm in 2 layers with overlap of seams. It turns out a multi-layered peculiar "substrate", which guarantees increased strength and durability of the base.

OSB Installation Technology Consider below.

Laying OSB on wooden floor

We particularly note that the wooden floors cannot be used a semi-dry cement-sand tie, to strip GWL, asbestos-cement plates and other similar materials.

The fact is that the thermal expansion coefficients and moisture absorption of these construction means do not correspond to similar wood indicators. The risk is the risk that the base may begin to rot under the leveling layer, mold and the like.

For the installation of OSB on the wooden floor, the following tools will be required:

electrolake to remove excess protruding parts;
hammer or screwdriver;
electric drill;
hydroelectory;
nails or self-tapping screws;
roulette and construction pencil;
hacksaw or electrolybiz;

From the building materials, the rack will additionally need to form a lag 4x5cm, 3x4 cm, insulation (mineral wool, eco-cm, ceramzite) or soundproofing material, as well as antiseptic and spacinal compositions for filling the pits, chosen at the base.

Mounting begins with wooden floor preparation. The surface must be thoroughly examined, the protruding parts to rush, and the pits and other defects are sharpened by quick-drying repairs. It can be a special putty on wood, blitz cement or simply sawdust, mixed with PVA glue.

Before laying OSB from a rough floor, plinth, nails and other irregularities are first removed.

To protect against mold and bug, the base should be covered with several layers of flaky-protein impregnation or primer with antiseptic additives. Ideally, you can also cover lacquer, but it rarely who does. The term of full drying is at least 3 days.

The next stage is the frame. Lagas also requires protection, so the bars are processed by bioprotective compositions, cut down the size of the room and are mounted to the floor with screws at a distance of 30-60 cm in parallel to each other. Equality is checked by a hydrorer, thin dies can be put for fitting under the rail. In the gaps, the heat-insulating or noise-repeating material is placed.

The finishing stage of the draft floor is the fastening of OSB plates to the frame with their own hands using self-tapping screws or nails. Sheets are placed, if necessary, it is carried out corresponding to cutting, and tightly fixed to lags.

Be sure to leave the thermocomptation gaps between the wall and the sheets of the OSB width of 2-5 mm. The distance between adjacent plates should be left optional.

After the end of the work, you need to check the resulting base level. If there are irregularities in the joints of the joints, they can be sileted with grinding or simply sandpaper. Additionally, for the ventilation of the cake, it is recommended to drill a seaside drill with several holes.

If you roll the OSP on a wooden base without lag, then the floor should be quite smooth, dry and durable. In this case, you can only do without self-draws and a screwdriver, and the alignment can be spent the day. The coating will turn out to be appropriate, if the materials are fixed with each other not only around the perimeter, but also the cross will increase over the entire area of \u200b\u200bthe sheet.

Installation of OSB on concrete floor

The draft floor from oriented chips can only be formed on a dry, "mature" concrete with humidity no more than 6%. But even in this case, it is recommended to use a waterproofing film, a membrane or a coating composition. If you put an OSB without this protection, mold, fungi, foci of rotting may appear on the basis of excessive humidity.

To lay the sheets with their own hands directly on the concrete basis, the use of panels with a thickness of 10-16 mm is recommended. Such alignment is allowed with drops to 2 mm on 2 m 2. This is enough to make the draft floor warm and smooth. Installation begins with floorproofing flooring. Shakes are fixed with adhesive tape. The sheets of OSB are applied on top and tightly fasten with self-draws. A gap of 2-3 mm should remain between the wall and the edge of the draft floor.

Lagi + insulation + OSB - one of the correct laying options

If the lags are installed, then the bars are first fixed on top of the film, the heat or soundproofing material is installed in the intervals, then everything is closed on top of the OSB sheets. Polyfoam, EPPS and other types of insulation can be used as a thermal insulator.

To qualitatively make the draft floor on the lags or on the ground, do not forget to constantly check the work done by the hydrorem. This will minimize the differences and to correct errors in time.

OSB or OSP (oriented chipboard) is a relatively new building material that has become a successful alternative to plywood and chipboard. The role of OSB in frame construction, with the insulation of standard houses. Especially often with the help of PSI form and align the floor surfaces. About how to do this to do this today and talk.

Types of OSB plates and their characteristics

OSB - plates consisting of several layers with compressive and glued with waterproof wood chips. Its gluing is performed in 3 layers. In the outer layers, the seams laid along the length of the panel, and inside - perpendicularly. Such a location gives an OSP strength, allows you to hardly hold fasteners.

The construction includes the following types of OSB:

OSB-2 - panels with low moisture resistance. They are used only for internal work in dry rooms.
OSB-3 - universal material. Withstands increased humidity and indoors, and outside. A large margin of durability allows you to widely use it in construction.
OSB-4 - the most durable and moisture-resistant plates. They are used to form bearing structures in conditions of high humidity.

For construction and alignment of floors, OSB-3 sheets are usually used, which perfectly withstand the burden from furniture, equipment, movement of people.

When aligning small floor defects, it is enough to apply OSB plates with a thickness of 10 mm. Surfaces with significant beatings and potholes will require a 10-15 mm material. If the creation of the floor on the lags is to be created, the thickness of the used OSB plates should be at least 15-25 mm.

For flooring of rough floors under the finish coating, wood plates, such as plywood and OSB, are widely used. Compare these two material in the next article :.

OSB plates are used as smooth and durable bases for various modern coatings - parquet, tile, linoleum, laminate, carpet. The main functions of the oriented chipboard are:

Creating an outdoor surface. OSB is a popular material for creating a draft floor on lags. At the same time, the plates can be found on both the upper side of the lag and at the bottom.
Aligning surface. Installation of OSB on wooden or concrete floor will help create an absolutely smooth surface suitable for laying the finishing coating.
Heat insulation. OSB plate by 90% consists of natural wood chips with high thermal insulation properties. Accordingly, the OSB floor does not allow heat to evaporate and holds it indoors.
Noise isolation. The multilayer dense structure of the OSP reliably absorbs any kind of noise.

Consider several popular OSP laying technologies for different bases.

Installation of OSB plates on concrete floor (cement tie)

Let's start with the easiest situation - alignment by plates of a PCP concrete base. Works are performed according to such a scheme.

From the concrete base, the garbage sweeps, remove the dust with a vacuum cleaner. The surface must be absolutely clean to ensure the adhesion of the mounting glue. The base is covered with primer. It also contributes to the best adhesion of glue with the base. In addition, the primer creates a dense film on the surface, which does not allow the screed "dust" during operation.

OSP is decomposed on the surface, if necessary, they are trimmed with an electrolovka or circular saw. On the Parquet Glue on a rubber-based OSB on the wrong side, using a toothed spatula for uniformity. Print sheets to concrete base.

Additionally, the OSP is fixed by clogged dowels. For guaranteed holding, the dowel is clogged around the perimeter every 20-30 cm. If the floor is even, the installation is carried out in a dry residential room, then it is enough to fix a dowel at the corners of each plate (subject to the mandatory use of high-quality glue!).

When laying between the plates leave dilatation seams with a thickness of 3 mm. On the perimeter of the room, between the OSP and the wall, the seam should be 12 mm. These gaps are needed to compensate for temperature and humidity extensions (swolves) of the OSP during operation.

At the last stage of work, the base of OSB is cleaned of dust and garbage. The seams between the wall and plates are filled with mounting foam. The term of it is drying - 3-4 hours. Surplus the dry foam, speaking outside the surface, cut into a sharp knife.

Installation of OSB plates on board flooring

Laying OSB on the old wooden floor helps to align the surface and prepare it under the installation of the finish coating. Installation is carried out in this way:

To begin with, with the help of a level or rule, the localization of irregularities (swirling, depression) of the board of the board is determined.
The boards that "walk" or are too towering over the general level, attract to the lags of the dowels, beating them into the material. In some cases, to eliminate the screenshots and chance of boards, the floor has to be sought with a replacement (repair) lag.
It is believed from the flooring in the glands, blooming and protrusions are erased by grinding or sandpaper.
Along the floor lay out OSB plates, with displacement of the seams of each next row. Cross-shakes should not be! Provide dilatation gaps (between the plates - 3 mm, along the perimeter of the walls - 12 mm).
In the stoves drill holes. Their diameter should coincide with the diameter of the thread of the tree of the tree, which were chosen to fix an osp to the floor. The holes are drilled around the perimeter of the plates every 20-30 cm, they perform cencing under the hats of the screws.
Self-assembly on the wood is attracted to the floor. The recommended dynam of self-samples is at least 45 mm.
If you wish to make the floor more durable, the second OSB layer is mounted. The seams of the overlying and underlying layers must be laid with a displacement of 20-30 cm.
Deformation gaps in the walls are filled with mounting foam, which is cut after drying.

This is completed on this process.

Laying OSP on lags on a concrete basis

If there is a concrete base (for example, overlapping slabs), the device lag and the casing of their OSB-sheets allows you to create a smooth floor without the use of wet aligning screeds. And also to accommodate insulation, moisture and noise insulating materials into the design.

Consider the technology of creating sex from OSB on lags on the existing concrete base. Lags (wooden bars) are fixed on concrete ceiling with dowels or anchors.

The wider distance between the lags, the thicker used OSB-plates. If the step is 40 mm, then the minimum OSB thickness is 15-18 mm, if the step is 50 cm - thickness 18-22 mm, if 60 cm - 22 mm and more.

Thanks to the lags, space and concrete overlap creates space. It can be used with benefit by laying insulating material. For example, the floors of the first floors are often cold, so there can be a heat insulator between lags: mineral wool, foam, EPPS, etc. In the presence of a wet basement under the flooded basement, the floor design is complemented by vapor insulation films or membranes.

OSP plates are lagged across the lag. The seams between adjacent plates (in width) should go strictly in the middle of the lags. When installing it is recommended to leave dilatation gaps (3 mm - between the plates, 12 mm - between the OSP and the wall)

Sheets fix to lags with self-draws or nails (spiral, ring). Step of fasteners: along the perimeter of sheets - 15 mm, on intermediate (additional) supports - 30 mm. Nails (or screws) fixing the plates around the perimeter are located at a distance of at least 1 cm from the edge (so that the osp is cracked). The fasteners are chosen so that their length is more than 2.5 times the stoves used.

How fasteners fasteners PRP on lags in a regular urban apartment, look at the video:

Creating a draft floor from OSB on lags

OSB laying on wooden lags is the simplest way to get durable and reliable black floor. This technology is particularly relevant with a column, pile, pile-screw foundation. Order of work:

On the foundation mounted lags. The step lag must match the thickness of the OSB slabs used (the more step, the greater the thickness).
Perform the draft floor. To do this, along the lag nourish holding bars, they are placed on them and secure OSP slabs. The surface facing the soil is covered with waterproofing preparations, such as bitumen mastic.
On top OSB laid a layer of vaporizolation.
Place insulating material, such as foam, mineral wool slabs, eco-art, etc.
Close the insulation by another OSB layer. The mount is carried out in the same way as when laying OSB on lags according to the existing concrete base (the technology is described in the previous paragraph).

On this work process is considered completed.

OSB processing for different finish coatings

Durable, solid and smooth surface makes OSB universal base under all modern types of finish flooring. How to cover the floor from OSB? Here are some popular solutions:

Varnish or paint. In this case, OSB slabs will act as piston floors that will need only decorative trim with paint and varnishes. No additional preparation of OSP sheets require, it is enough to clean them from dust and apply 2-3 layers of varnish (paint).
Rolled materials - linoleum and carpet. When laying rolled materials, it is necessary to trace the joints between OSB plates to be lined with the rest of the surface. All irregularities are desirable to remove with grinding paper. Compensation clearances - fill with elastic sealant.
Tile (ceramic, vinyl, quartzinyl, rubber, etc.). To keep the tile on the basis of an OSP, it is necessary to ensure its stillness. For this, the lags have more often than the thickness of the sheets requires. The step between the mounting elements is also reduced. The tile is glued to PCA using special glue suitable for the wooden surface and the tile used.
Laminate - Finish coating, which is fixed by the "floating" method, without a hard fastening of the lamellas. This coating is hard enough, so you do not need to prepare OSB. Minor irregularities that can be in places of stoves are leveled by the substrate.

What exactly choose is to solve only you.

Using OSB allows you to cheap and quickly align the existing wooden or concrete floor. And if necessary, create it from zero to lags. The surface of OSB will not require expensive finishes, additional alignment, coating with moisture resistant compositions. This is an excellent choice for those who want to create high-quality floor with minimal effort.

OSB plate is a modern building material, which in its characteristics successfully replaced the chipboard and Fane. These are used in the construction of frame houses, and for insulation. Also use these products for the arrangement of draft coatings. The floor from OSB is a great opportunity inexpensively and with minimal effort to align a concrete tie or

What is OSB?

The oriented chipboard consists of several layers of pressed, and then with special water-resistant resins glue it into three layers. On the outer sides of the seams is placed along the length, inside - perpendicularly. This solution gives new building material a special strength.

Types of OSB plates

In construction work, as well as during repair, several types of these plates are used. So, OSB-2 is a panel that has very low moisture resistance. This solution is suitable only for internal works in dry rooms.

OSB-3 is a more versatile plate. Among the characteristics is high resistance to moisture, both indoors and outside. Also, the stove has a huge margin of safety.

OSB-4 is the most durable and most moisture-resistant materials. They apply only to create bearing structures in conditions where the level of humidity is especially high.

What plates fit for the floor?

If you need to make the floor from OSB, then the OSB-3 is best for these purposes. These plates are perfectly withstanding the impact of heavy furniture, various equipment and other mechanical loads.

Panel data are used for before laying the finishing floor covering. If there are only small defects on a rough concrete or wooden base, then the thickness of the sheets in this case should be no more than 10 mm. If large protrusions and recesses are present on the surface, it is best to use thicker plates. The thickness of them in this case should be from 10 to 15 mm.

If you plan to build the floor on the lags, then even thicker sheets should be used - the thickness should be from 15 to 25 mm.

Choice rules

It is worth knowing some of the rules of choice. It is very important who made sheets. Experts with experience recommend to stop the choice of products from Canada or Europe. As for the size, the standard for this material is considered to be 2.44x1.22 m.

Basic functions of OSB plates

Such panels are used to create a smooth and most strong base under various types of modern finishing flooring. It can be parquet, ceramic tile, laminate, carpet.

This is the perfect option for alignment of floors. Plywood used earlier does not have such high characteristics. If the choice is - Paul Plywood or OSB, then the latter will be more durable.

Advantages and disadvantages

Among the advantages of such a building material also highlight a sufficiently high density - even a large rat will not be able to damage this base. High resistance to moisture impact allows the use of material anywhere - you can retain these sheets in the baths, as well as in various unheated rooms.

Laying OSB on the floor will not require special skills - it will be able to do a completely any domestic master, which is a serious advantage. To improve the draft base, it is enough to use the usual building level, hacksaw and a hammer.

OSB is an excellent opportunity to save, since the price of these plates is low. One element will be enough to treat a serious area. You can also highlight high strength characteristics - even at large loads, the floor will not be deformed.

Installation of OSB on concrete floor

Imagine this situation - there is a terrible curve for alignment, you can apply the following scheme. Technology is relevant for any concrete surfaces.

First of all, the work surface should be cleaned as much as possible. To do this, you can use either a vacuum cleaner or broom. It is necessary to ensure maximum purity, because the sheets will be glued with the mounting glue. Clean surface - high adhesion.

Then the purified base should be covered with primer. This will help glue better clutch with a concrete surface. In addition, the primer forms a sufficiently dense film at the screed, which will not give her dust in the process of use.

Then begin to lay the OSB plates on the floor. If necessary, cut the pieces to the desired size of the jigsaw or circular saw. From the wrong side, it is applied to the material only to choose only on a rubber basis - it is more effective for solving such a task. So that the glue can be applied to the most evenly, experienced specialists recommend using a gear spatula.

Additionally, the slab should be fixed by a clogged dowel. This is done for guaranteed and reliable retention. Score dowels best around the perimeter. The interval is 20-30 cm. If a concrete screed screed is smooth, and the installation is performed in a dry room, then you can fix the OSB only in the corners, but this is taking into account the fact that high-quality glue is applied.

In the process of laying between sheets, it is necessary to leave the deformation seams. Their width should be about 3 mm. All over the perimeter of the room also leave the seam in 12 mm - between the stove and the wall. These are special deformation gaps that, if necessary, be able to compensate for the expansion of materials. The floor from the OSB is practically ready.

In conclusion, it is necessary to carefully clean the resulting surface from the dust and various garbage accumulated there. The deformation seams are filled with mounting foam. Then the surfaces give to relax and dry for 4 hours. After that, it remains only to cut the foam, and you can lay the finish coating.

Installation of OSB on wooden floor

So, before making installation work, you should again prepare a basic basis. It is very important to pay attention to nails if they are. They must be drowning deep into the board. For this, the usual hammer and steel bolt is best suited. The diameter of the bolt should be equal to the diameter of the nail. If the floorboard during operation managed to come into disrepair, it must be restored using a ruble.

After that, you can proceed directly to the installation of OSB. First of all, pre-chopped sheets lay on the surface. Here, as in the case of installation on concrete, it is important to remember the need for deformation seams. For fastening the plates, it is best to apply a self-tapping screw, the length of which is 4 cm. The range of fastening elements is approximately 20-30 cm. Self-tapping caps are interposed inside the stove.

After the installation is over, it is recommended to grip joints. It can be made with hands, but if the area is serious, then it is suitable if you need the maximum effect, it is necessary to arm a vibration machine that is equipped with a grinding grid. Processing the plate is worth with maximum accuracy - you can easily make removing on its surface.

Installation of plates is extremely simple. It is clear to all craftsmen, how to make the floor from OSB. It is worth trying this new building material. It is effective, and it's nice to work with him.

More and more developers are used in the construction of OSB plates (OSB, OSP). Despite some relationship with the chipboard, this material is distinguished by the unique characteristics of waterproof, strength and elasticity, besides, it is much easier to its predecessor. The OSP is the further development of a chipped extruded sheet, but rather long wood chips (up to 14 cm) are compressed in the oriented chip plate (up to 14 cm). Their thickness is less than a millimeter, but chips in one layer are oriented in one direction, and the direction of the chips in each next layer is perpendicular to the previous one, which significantly improves the properties of the material.

What plates to use for the floor?

OSB plates, the number of layers in which can reach 3 or 4-x, are designed with non-amineral resins. Often, the use in the production of OSB products containing formaldehyde makes it impossible to use plates in the interior decoration, but sheets made according to the OSB-3 standard are not distinguished by harmful substances and can be mounted in rooms with high humidity. OSB plates of this type are best suited for floor mounting. Experts recommend to make sex coating from plates issued by well-known manufacturers. As a rule, the highest quality products are produced in European countries, Canada and the United States, in which the requirements for environmental requirements are most accurately followed.

The floor from the OSB can be a finish coating, as the outer texture of the slab looks quite interesting.

With it, it is possible to finish with other materials. Nevertheless, the installation itself requires a preparatory stage. How to align the floor before laying OSB-boards, will be described below.

Plate laying on concrete surface

Quite often, not to lose in the height of the ceilings in the room, the builders laid rals on the concrete tie. Of course, in this case, the base should be smooth. Ensure the perfect surface can be removed the old coating and the bay is new. Although the oriented marginal plates are not afraid of moisture, the base needs additional waterproofing. This will protect the space under the stove from the accumulation of condensate and the formation of fungus.

After laying on the surface of the rubberoid or polyethylene cleaned from the old screed or polyethylene are installed and mounted beam gypsum. For their alignment, level, bulk cord, roulette and transverse threads are used. Now details on how to align the floor with these devices:

At some distance from the floor on the wall there is a mark.
With the help of a water or laser level, another mark is made on it.
A horizontal line is littered with grated chalk cord between points.
The same operations are performed on the rest of the walls.
At the height of the alleged screed is a mark.
From the horizontal to it, the distance or tape measure is measured.
Dots are applied to the rest of the walls.
Marks are connected by lines.
In the walls on the lines screw screws.
From fasteners to fasteners on the opposite walls stretched the threads. It will be a plane screed. Lapered profiles are installed on them.
A flooded concrete is aligned with the rule. Its length should be wider than the gap between the beacons.

True, complete drying of the solution will occur 4 weeks after its fill, but after that you can start laying the OSB panels.

For their installation on a concrete base required:

toothed spatula;
perforator;
dowel-nails;
screwdriver;
a hammer;
parquet glue.

On the perfectly even base, it is enough to put one layer of 10 mm material. This is a good heat and noise insulator. Stage order Next.

The required number of OSB sheets is prepared. Their standard size is -2.44 x 1.22 m. If necessary, the plates are cut by a circular saw or a jigsaw, however, working the latter, it is difficult to provide smooth edges.
The glue is applied to the OSB and is distributed over the surface with a spatula.
Plates fit on the screed. Between them, it is necessary to leave a compensation gap of 3 mm.
At the corners of the OSB panel are drilled. Holes and concrete are made. Dowels are inserted into them.
Plates are fixed to the floor fastener.
It is enough to apply a few protective layers of varnish so that the floor from the OSB is cleaned.

Oriented chopping base under the pure layer

If you decide using OSB, align the floor under linoleum or other rolled material, then the gaps between the plates need to be lost, but for this you need to use elastic compositions like sealant. Laying the laminate on the surface of the OSB does not require any additional preparatory activities. But the installation of the tile requires a more rigid clutch panels (spike-grooves) with each other. True, the tile is steaming on the base from the OSP when it is laid on the lags. In addition, the OSB-stove is not able to provide reliable grip with ceramics. It needs to be laid another material, but about it later. In general, make a gasket between the screed and ceramic tiles from the oriented styling plate and simply does not make sense. On how to align the floor from OSB on wooden lags, tells on.

Back to the category

For BRUSIV, it is necessary to choose the most flat wood of coniferous rocks (pine, spruce, larch or fir). Wood moisture should not exceed 20%. If necessary, the bars need to be dried under the canopy. For small rooms, we can use lags with a cross section of 110 x 60 mm or 150 x 80 mm. If the length of the span in the room is more than 5 m, the bars of 220 x 180 mm are used. It is desirable that whole lags are installed in the span. The jokes are allowed in extreme cases. Make them better bills. On neighboring lags, the joints should be located not closer to ½ m from each other.

Now about the order of work:

Wood lag is processed by antiseptics.
Ruberoid is laid on the base of the mustache.
Along the opposite walls, 4 bars are coated horizontally. The horizontal is displayed using a level and twisted cord. The distance of the lag from the walls should be 2-3 cm.
If the base has drops in height, wooden lining are used to align the bottom strapping. The protrusions in the overlap are compensated by the decoration of certain areas on the lags.
Bottom bars are attached to the base with anchor screws or bolts with a cross section of 10 mm. Their length depends on the thickness of the bar and lining (it is added another 50 mm for fixing in concrete).
Cross bars are attached to the bottom strapping with the help of corners and screws. The step between them depends on the thickness of the OSB plates. For plates of 15 mm thickness, the distance between lags should be 450 mm, and for a 18 mm - 600 mm.
Ceramzite is falling asleep into the crate or another insulation and soundproofer is stacked.
Before fastening sheets, a moisture-repellent membrane is spilled.
OSB sheets are stacked.

As a rule, 2 layers of the oriented chipboard are placed on the lags. The second layer is stacked in the first one, so that the joints do not coincide. The gap between the joints of the panels should be 3 mm. The gap between the wall and the OSP is 12 mm. Short edges of the plates should be shrinking on the supporting bars. Shakes of long sides must be on the supports. For better contact of the surface of the OSB and bars are processed by mounting glue. Plates are screwed to lags with self-drawing along short edges. Step fasteners - 15 cm. Glue is applied between the upper and lower plates. The laying of the upper panels ends with screwing the screws at the edges of each sheet.

When the surface is approved on the lags, you can return to the question about laying the tile. OSB, although they do not provide a reliable connection with it, still serve as a solid base that cement-chip plates are stacked. They are attached to the previous coating using PVA and self-tapping screws. It is desirable that the joints of the CSP do not coincide with the places of compounds of the previous layer. It is necessary to withstand 2-millimeter compensating gaps between adjacent plates, as well as between the CSP and the wall. After that, you can already start laying the tile coating.

Thus, the device of the floor from the OSB and its alignment with this promising building material for the subsequent finishing finish is not particularly difficult from other methods of installation of the flooring. It can be stated that OSB-slabs are not the best option when preparing the base for laying ceramic tiles, but in the rest of the oriented chipboard are ready for full competition and with modern, and with traditional building materials.

Framework technologies that have long conquered the construction markets of Europe and North America are becoming increasingly popular in our country.

The number of country houses and cottages raised by this method is growing every year. The main advantages of framework technology: high construction speed and low cost.

This is achieved largely due to the use of special building materials - OSB plates, which are used both as black floors and for the construction of the walls of the building. In this regard, the owners of frame houses often have questions regarding their finishing finish, in particular, how to put tiles on the OSB plate.

What is OSB plate

Frame plate consists of wood chips

Oriented chipboard (Russian - OSP, English - OSB) is a relatively new material on our construction market. Constructively, OSB consists of several layers of pressed chips, fastened with each other by means of synthetic resins.

Each layer of chips is oriented in a particular side, and layers are located strictly perpendicular to each other. This makes it possible to get those wonderful technical qualities that this material differs from other wood composite materials (DVP, chipboard, plywood, etc.).

The main advantages of oriented chipboard are:

strength;
flexibility;
ease of processing;
small mass;
available cost.

Another advantage of the OSB-stove is its multifunctionality. Walls and floors made of it are subject to almost any kind of finish-treatment - painting, whitewash, plastering, etc. You can also put a tile or porcelain tile on the OSB-plates.

Difficulties of working with OSB

However, during finishing works with OSB, a number of rules must be observed so that the results do not disappoint you.

It must be remembered that the base of the OSB-slab consists of a tree. Consequently, the stove is intended to absorb moisture, which leads to its swelling and deformation.

Fruit fragile stove and has bad adhesion

As well as all sorts of wooden surfaces, the OSB panels have poor adhesion with adhesive compositions made on the basis of cement, therefore most tiled adhesives will not be able to provide reliable tile grip with the surface of the chipboard. To do this, make a number of works to increase the adhesion of the carrier surface.

Another feature of OSB is its flexibility that does not give the panels to crack under the influence of physical exertion. Under the weight of the people moving around the room, the stove will be barely noticeably fade.

The tile compared to OSB is almost unable to curled. As a result, the tile flooring will inevitably flaw from the base, and the seams between the tiles crackle.

To avoid this, you will have to make the surface of the slab as a rigid.

Place the plates only on very durable smooth bases.

In order for the surface of the chipboard to be solid and did not bended, it should be laid on sufficiently strong bases. If we are talking about flooring, the OSB-slabs can be put directly on the concrete overlap. The main requirement to the layer is - it should be smooth in the horizontal direction.

Any bends, hillocks or depressions can lead to the fact that the OSB panel will be loosened to the concrete surface, and this, in turn, will lead to the flexing of the chipboard and the gradual detachment of the tile coating.

With small defects of rough concrete floors, you can do the "local measures" in the form of racing the bugarhs and the glands of pickles, or embedding the pits and cracks with putty.

However, with significant horizontal slopes of the base, such semi-dimensions will no longer do.

To align the surface of the floors, it will be necessary to produce a concrete tie. For these purposes, you can use the ready-made dry mixtures of the sandbetone, which can be purchased at any construction store. To prepare a solution ready for use from a dry mix, it should be diluted with water in the proportions specified on the package.

To obtain the highest possible solution, when it prepared, it is necessary to strictly follow the instructions from the manufacturer.

For screeds need sand, cement and water

You can also prepare a solution for a screed of floors with your own hands. To do this, you will need cement brand M-300 or M-400, water and coarse sand.

In case the thickness of the concrete screed is supposed to be more than 30 mm, instead of sand it will be advisable to take fine-flow gravel.

The table shows the proportions of the preparation of the solution for the cement-sand tie.

The easiest way to make lighthouses from a metal profile

Next, with the help of a laser or construction level, we exhibit horizontal guides - the so-called beacons. They can be made of metal profiles for drywall or smooth wooden plates. The beacons are installed on the substrates from brick pieces, thawed wreckage, etc., parallel to each other with an interval of 0.7 - 1 m.

Thus, the beacons shall share a room for several compartments stretched along the entire room. Pulling the concrete from the most distant compartment from the front door, aligning concrete in the level of beacons using a long rule. After the concrete is completely dry, you can start styling on the tie of OSB plates.

The time of the complete set of the concrete fill fortress is about 4 weeks. If you attach a chipboard to the screed before this, the concrete around the dowels can simply be reassigned during the installation.

As a result, the stove will "walk", and laid on her tile lagging behind the base.

Laying OSB-panels on the wooden basis

Durable and smooth flooring will save the slabs from deformation

Most often, the OSB panels are used in low-rise frame construction, where the main building material is a tree. In this case, as a basis that makes a stroke plate with a more rigid, you can use a wooden boardwalk.

It is possible to perform it as a conventional wooden floor, which is stacked and fixed using the Self-Plate screws. So that the surface of the plate turned out to be smooth and did not bend during operation, the boarding floor must be made as strong as possible and smooth.

If the OSB-plate acts as a rough floor, which is often in frame construction, it is possible to make it more durable and rigid with a thick sheet of plasterboard or cement-chipboard.

These materials will not only give the rigidity of OSB, but will allow you to get a sufficiently strong coupling with tiled glue.

For laying on the floor, we should take moisture-resistant grades of plasterboard. If the owner decided to save on the floors and laid the usual GLK, with the first leakage of water supply or heating pipes, he would have to open the floors and change the spots of GLC.

The grid will help hold the glue on the surface of the plates

The third version of the preparation of the base from OSB to the tile laying is fixing on the surface of the plaster mesh plate. In this case, the tile glue will hold onto the grid that will simultaneously perform a reinforcing role.

However, as practice shows, this method is more suitable for facing the walls of the walls than the floors. On the fees, the tile under the weight of furniture and people gradually begins to move away from the draft floors from the OSB.

Kafel Laying on Walls from OSB

When lining the cafeter of walls from OSB panels can be encountered with the same difficulties as with flooring flooring from ceramic tiles. To increase the adhesion (hitch) between OSB and tiled glue, except for the already mentioned plaster grid, you can apply primers and special adhesive mixtures. On how to stick the tile in the frame house, look at this video:

Surface primer

With the help of primer, you can significantly increase the adhesion of any building materials, is no exception and stove.

Before applying a layer of primer on the panel, it will need to carefully clean up with a large skirt or grinding machine.

After that, with a roller or painting brush, the first layer of primer is applied.

For the best effect, you should use at least two layers - the second is applied after complete drying of the first layer (after about 10 to 12 h).

Selection of adhesive composition

When mounting a tile on OSB should not save on the glue. Since conventional tile adhesives on a cement basis cannot provide a sufficient clutch with the surface, you will need to find a more "strong" option.

A good property to glue any materials possesses the construction glue PVA. It will be able to firmly connect the surface of the ceramic tile and the OSB plate.

Small squares can be seized with liquid nails

If the area of \u200b\u200bthe cladding is not so large, for example, a kitchen apron from a ceramic tile, then you can use for gluing liquid nails tiles from any manufacturer.

However, with a significant area of \u200b\u200bthe wall, this option will be sufficiently costly, and the dismantling of tiles in the future will be very difficult. With the same success for sticking a tile instead of "liquid nails" any silicone sealant can be used.

Also, when laying tiles on problem bases, such adhesive compositions have proven to be well established as "Cerezite" -SM, "composed" -24a, "Knauf-Flex" containing special polymer additives in its composition.

Cafle Laying

Note the bottom of the lane from which the masonry will begin

After all the preparatory work is completed, you can proceed directly to the laying of the tile.

First of all, with the help of a laser or hydraulic level, we make the wall markup.

We note the horizontal strip from below, along which the first row of tiles will be pasted. The following tools will need to lay the tile:

toothed spatula with teeth length 5 - 10 mm;
laser or hydraulic level;
molding with a rubber surface;
rubber grouting spatula;
corner struts;
platekorez.

The lower level is noted by the rail - it will hold the slab tile

Along the feature denoting the lower horizontal level, with the help of self-tapping screws to the OSB-cooker, secure a metal profile or a wooden slaughter.

She will act as a support - the first row of tiles will be put on it. Otherwise, the tiles can break down the fresh solutions.

The gear spatula is applied to the surface of a glue solution along the entire lower row. As a result, we get a wavy structure: it is necessary for the convenience of adjusting the tiles in depth. With the help of a lung tapping with a rubber hammer, you can deepen the protruding corners of the tile.

After mounting the first row to the upper corners, we insert cross-shaped corner struts and begin the laying of the second row. The struts will allow you to observe the same seam size between all tiles.

Usually after laying 4 - 6 rows of tiles make a break to give glue to "grab". Otherwise, the lower rows will put the excess weight, under the action of which they can simply move away from the surface of the OSB panel, to work out and sprinkle.

12 hours after the completion of the masonry, it is possible to begin the smelting of the seams using a special cloud solution and a rubber spatula.

Installation of flooring

As you can see, laying a tile on the walls from OSB is practically no different from work on the facing of concrete or brick walls. The same can be said about laying a ceramic flooring.

After the work of all the preparatory work, we make flooding of floors with such a calculation so that the central line is perpendicular to the wall in which the front door is located.

We find the middle of this wall and at an angle of 90 degrees are carried out (stretching the thread). We produce the same operation with a neighboring wall. In the end, we get the intersection of two lines exactly in the middle of the room. From this place and begin to put the floor ceramic tile, moving along the stretched perpendicular threads.

When approaching the walls, the tile is cut along the desired size using stoveturis.
