Laying plywood on a wooden floor - eliminating imperfections in the plank base. Laying plywood on the floor under linoleum, laminate or parquet Plywood primer for linoleum

Linoleum is a rather demanding type of flooring. It requires a perfectly flat base. Therefore, plywood is often laid under linoleum on a wooden floor in order to smooth out all the unevenness and roughness of the wood.

Plywood requirements

Plywood is a material that is made from hygroscopic wood, so it is still not recommended to level floors in a damp room. Humidity in the room for a long time should not exceed 68%, and during the day should be within 78%. If plywood is not available, then the percentage is reduced to 60. At the same time, the room temperature must be maintained within the range from 18 to 27 ° C.

Attention! If you do not adhere to the above requirements for indoor conditions, then after a couple of months our plywood base will begin to delaminate.

To improve the quality characteristics and service life of plywood, it is necessary to impregnate the material with polyvinyl acetate putty in the process. This tool is inexpensive but effective. The impregnation is carried out first on one side, and when spots appear on the other side of the sheet, then it is possible to soak it in two layers.

Drying is carried out in a horizontal position of the sheet and it will take more than 3 days, while the temperature should be room temperature. After such impregnation, the sheets must also be treated with an antiseptic for wood products. To increase the strength, you can also open the plywood with two layers of acrylic varnish.

Note! The thickness of plywood for linoleum on a wooden floor should not be less than 1.2 cm, since you will have to do with more than one layer of sheet material.

It is recommended to lay hardwood veneer plywood under linoleum, it is more durable than coniferous counterparts. Also, preference should be given to plywood marked FC or FBA. The latter is impregnated with natural compounds, being an environmentally friendly material.

Preparing plywood and base for laying

Before starting work, everything must be carefully prepared, including the plywood itself. Like any material made from wood, plywood takes time to acclimate. Under equal conditions (temperature and humidity) in the warehouse and in the house, this period will be only a day. If the temperature difference is 2-8 ° C, then 3 days, with a larger difference it will take a week.

Important! Plywood sheets are acclimatized horizontally.

Before work, any surface of the base must be checked not only for integrity, but also for moisture evaporation. For this, a square of polyethylene is spread over 1 sq. m of the base. In the center, the material is lifted, and on the edges, on the contrary, it is pressed with weights. Further, if the bubble has already fogged up during the day, then plywood cannot be laid in the room.

When drops appear on the polyethylene within 3 days, the wooden floor must be disassembled and reconstructed, since, most likely, the boards have already rotted from the inside. In this case, you can cover plywood with the material improvements suggested above. If, within 5 days, the condensation does not come out, then you can lay plywood.

Now do not forget about preparing the base itself for plywood laying. Remove the skirting boards, if any. The floor must be checked for integrity, whether there is rotting, insect damage, cracks and chips. If there is damage, they must be removed; if necessary, whole boards are replaced with new ones.

All small cracks and chips are eliminated with a putty, but if the crevices are more than 5 mm wide, then patches are necessary. After all reconstructive measures, the surface must be leveled; it is recommended to do this with a grinder. After that, the surface is cleaned of various debris, dust and traces of dirt.

Laying plywood on glue

Plywood sheets can be stacked entirely if space permits, or you can cut them into several pieces. We lay them on the floor with an offset to the floor of the sheet, like bricks. A distance of about 1 cm should remain to the wall, but no more than 2-3 mm between the sheets themselves. When the fitting and fitting of the plywood pieces is finished, you can start applying the glue.

As an adhesive, you can use either a special glue for wood or mastic (mixed PVA glue with stucco to a thick state). We lubricate the floor surface well with the composition, carefully filling the cracks and smoothing out irregularities. On top of the product, we lay sheets of plywood with their obligatory fixation with self-tapping screws.

The screws should be spaced from each other at a distance of about 15 cm, the head should be deepened as much as possible so that they do not create problems later when laying linoleum. All the remaining gaps between the sheets themselves and the heads of the embedded fasteners are putty and grinded. Plywood joints can even be finished with a planer.

The video will demonstrate in more detail the entire process of laying plywood under linoleum on a wooden floor in the best possible way.

When the plywood is dry, it can be treated with linseed oil (hot), painted or treated with other protective compounds. After that, you can start laying linoleum, having previously checked the evenness of the resulting surface.

Preparing the floor for linoleum flooring is a mandatory stage of work, which is performed regardless of the quality of the base. In some cases, it will be enough to sort out the existing floor structure, somewhere you have to change all the supporting elements.

Laying plywood on a wooden floor under linoleum is the most affordable and reliable way to level the base. This technology is widely used and time-tested. This is especially true for old floors, where, in addition to replacing the bearing logs, you need to grind or plane the floorboards.

The advantages of this method

Linoleum belongs to the class of roll coatings. It is distinguished by elasticity, resilience, strength. But, despite these qualities, it remains a soft material.

If the supporting base has pronounced irregularities, then over time they will necessarily appear on the surface of the linoleum. This will lead to a decrease in both the decorative qualities of the material and its service life.

It is important that the installation substrate is level, dry and clean. The presence of chips, potholes, cracks and changes in height is not allowed. Plywood allows you to solve these problems, thereby creating a dense, solid and monolithic base.

Plywood flooring can be installed in one or two layers

Among the benefits of using plywood are the following:

  • strength - solid and durable flooring that does not sag over time;
  • ease of installation - in the process of work, a complete dismantling of the old boardwalk is not required;
  • sealing - an additional layer formed by plywood sheets acts as a barrier that protects the floor and its structure;
  • cost - plywood has an acceptable cost, which reduces the overall cost of floor renovation.

This leveling technology can be used for almost any floor covering - laminate, flexible vinyl tiles, parquet, parquet board. That is, after some time, you can easily remove the linoleum and put any other suitable material in its place.

The most important disadvantage of leveling the floor with plywood for linoleum is that the layer of plywood sheets and flooring will take up additional space from the height of the room. In the case of linoleum - about 3 cm. Laminate and parquet - up to 5 cm.

It is not recommended to use plywood in bathrooms and rooms where there is a risk of ingress of large amounts of water and constant humidity. In the kitchen or in the hallway, there is also a risk, but if linoleum is laid using technology, then the base is reliably protected and sealed.

The choice of plywood for laying

When laying in the kitchen or hallway, it is better to choose a moisture-resistant material.

Before starting work, it is important to choose the right plywood sheets. There are a lot of varieties of material, but we recommend using the following:

  • FKM and FK are waterproof and moisture resistant plywood, respectively. It is the optimal material for laying under linoleum. It is made on the basis of melamine and kerbamide resins. Environmentally friendly for human health. Differs in high strength and elasticity.
  • NSh - unpolished plywood sheets used as a rough surface for further finishing. When laying on the floor, sanding will be required with an emery paper or sander.
  • Ш1 - sanded plywood sheet from the front side. On the back side there is an adhesive base. It is used for cladding a rough base and making furniture.
  • Ш2 - sanded plywood for finishing. Recommended only for dry rooms with constant temperature and central heating.

The best type of plywood is a sheet marked "ФКМ" and "ФМ". The thickness of plywood for linoleum flooring must be at least 10 mm. It is recommended to use sheets with a thickness of 14 to 22 m, depending on the load and the amount of furniture in the room.

When laying plywood, it is necessary to pre-treat with an antiseptic. This will prevent and protect the material from decay processes, the formation of harmful microorganisms and fungi. If desired, you can cover the sheets with acrylic varnish, which will increase their strength.

Preparing the subfloor before laying

During the preparation process, it is required to replace all damaged elements

The sub-base for laying plywood should be relatively flat and dry. It is not recommended to carry out the flooring without preliminary preparation, since even an even plywood layer is not able to correct the existing deflections and general curvature of the base.

It is better to perform this preparation before purchasing the material, since it will be necessary to completely sort out the floor. It will not work to store and leave plywood for acclimatization in this room.

The process of renovating an old wooden floor consists of the following steps:

  1. If you can see with the naked eye that the level of the floor relative to the horizon is "overwhelmed", then you should start removing the plinth and boardwalk.
  2. In case of minor deviations, it is enough to open the damaged floorboards and the problem area and fix the problem that has arisen.
  3. After opening it is necessary to remove the heat-insulating material and insulation. Next, you need to clean the logs and supporting beams from dirt. After that, carefully inspect for rot, cracked and damaged elements.
  4. For the repair of load-bearing lags, a timber of a suitable convenient section is used. The damaged area is partially replaced by an insert made of new wood, or completely replaced.
  5. After replacement, all wooden structural elements are treated with an antiseptic or special water-repellent impregnation. If necessary, the treatment can be applied in 2 layers.
  6. The laying of vapor barrier and heat-insulating materials is in progress. If required, the necessary communications are laid. The old rough flooring is being mounted. Damaged floorboards are replaced with a new one.

At the final stage, floorboards covered with paint or other varnish-and-paint coating are cleaned with a spatula and sandpaper. This is done in order to remove the peeled coating.

If the board is clean and has not previously been covered with paint, then an additional antiseptic treatment can be performed, which will protect the floorboards from the formation of rot and mold.

Layout and adjustment of plywood

The marking and fitting of plywood for linoleum is carried out two days after the delivery of the material to the work site. This is necessary in order for the plywood to acclimatize to the current conditions - temperature and humidity in the room.

The technology assumes that plywood will be laid with square blanks with offset or overlapping joints. The size of the workpiece is 60 × 60 cm or more. The gap between the wall is 8-10 mm, between adjacent sheets - up to 4 mm. The offset of the sheet relative to the previous row is 20-30 cm.

Sheets should be square or rectangular

It is advisable to choose the size of the sheet so that the entire area of ​​the floor surface is filled with solid sheets. Regularly shaped narrow canvases will only be used at the beginning of the row and in places where the floor load is minimal.

Before cutting the sheets, you should draw up a diagram of their location. To do this, you need to measure the room and depict it on a reduced scale on any convenient paper. Further, the diagram shows the sheets in the order in which they are planned to be laid on the floor. It is more convenient to lay from the far corner towards the exit.

An electric jigsaw is used for cutting. After cutting, you need to carefully check the end of the sheet and make sure that it is intact, no cracks or chips have appeared.

Subfloor laying technology

Scheme of arrangement of sheets from the center and corner of the room

Plywood is laid on the floor under the linoleum after the antiseptic has dried. To carry out the work, you need to prepare a screwdriver, wood screws and a bubble level. If possible, you should rent an electric drill for countersink holes.

When facing a plank sub-floor, the sheet is laid perpendicular to the location of the floorboards. In this case, the seams between the plywood will not line up with the gaps between the floorboard.

The technology for laying plywood sheets on a wooden base is carried out in the following order:

  1. A sheet of plywood, according to the diagram drawn up earlier, is laid in place and aligned with the wall. The technological gap between the wall is at least 8 mm.
  2. Next, the holes for the fasteners are countersinked. After that, you can fix the sheet. The step between the screws is 15-20 cm. The screw cap must be sunk so as not to damage the substrate and linoleum.
  3. The second sheet is mounted with a gap of 3 mm relative to the first. The process of fixing to the floor is the same. Work continues until the completion of the installation of the first row.
  4. The second row starts with a short belt to provide a breakaway. Further work is carried out according to the actions described above.
  5. After the completion of the installation work, the quality of fixing the plywood sheets, the leveling is checked, and the room is cleaned. During the cleaning process, it is required to thoroughly clean the seams from shavings and dust.

The work of laying plywood on a wooden floor does not cause any particular difficulties. The bulk of work is devoted to the process of preparing neglected or old floors, when a complete search and replacement of damaged elements is required.

A similar method can be used to level concrete foundations for further linoleum flooring. In this case, the plywood is fixed either on pre-equipped logs, or mounted on special anchors that are attached directly to the ceiling.

Laying plywood sheets on a slatted floor has some advantages over other flooring methods. So, a plywood floor allows you to:

  • create a continuous flooring that does not acquire unnecessary relief over time;
  • do not engage in additional dismantling of the old coating;
  • significantly reduce the cost of work, reduce the labor intensity of the process;
  • use moisture resistant types of plywood for additional protection of wooden floors in bathrooms, kitchens and washrooms;
  • have a minimum of seams between the structural elements of the floors, which are the weak point of this system.

Technology of laying plywood on a wooden floor

Stage 1. Preparing the old coating

First, the condition of the old floor is assessed. It is necessary to pay attention to the absence of elements damaged by mold and rot. If damage occurs, it is imperative to replace the old subfloors with new ones. Such damage to the surface indicates high humidity in the room. Its source should be identified for further elimination.

If the floors have cracks and holes, their width should not exceed 5 cm. Otherwise, restoration of the old flooring will be required. As a rule, prefabricated elements of any wooden surface deform over time. This, in turn, leads to the appearance of relief. To eliminate this problem, the floors should be sanded according to the following scheme.

  1. You need to get a sander. Better to rent it, because with a one-time do-it-yourself repair, it is impractical to buy such an expensive technique.
  2. Loose elements should be secured. The floorboards must be secured with wedges and nails. By the way, this will help prevent floors from squeaking in the future. During use, the nail heads are sunk completely into the board. This will prevent damage to the machine when sanding.
  3. All metal elements - screws and staples must be removed from the floor surface. If nails are found sticking out, they, as mentioned above, are hammered in flush with the boards.
  4. The direct grinding process takes place diagonally across the room. Provide an overlap of the processing strips. The typewriter does not need to be held for a long time in one area. It should not be forcibly driven, as this will create unevenness on the floor surface.

Stage 2. Preparation of plywood sheets

It is important to understand that plywood is a wood material, so its parameters may change subject to temperature and humidity changes. Before using plywood sheets, they should be kept indoors for some time to stabilize the humidity.

If the plywood was stored before the purchase in conditions close to those where it will be used after the purchase, then it is enough for it to lie in the room for a day. If the material was stored in a warehouse prior to purchase, where storage conditions differ from those in residential premises, then the correct decision would be to leave the material stored for 5 days at room temperature.

Stage 3. Plywood cutting

Sheets are laid out throughout the room, sawn with a jigsaw. The fact is that laying a rough plywood floor with solid elements is not the best option. It is better to cut them into smaller elements in order to minimize possible deformation processes of the sheets. For example, a standard plywood sheet 1.5x1.5 m is sawn into 4 pieces.

Each element should be numbered so as not to confuse the order of fixing the sheets during work. When laying out the sawn elements, it is necessary to take into account the gaps between the sheets equal to 2-4 mm. The distance between the wall and the plywood sheets should be 8-10 mm. These gaps are designed to compensate for the expansion of the material under load on the coating and with temperature changes.

Stage 4. Plywood impregnation

Plywood sheets mounted under linoleum need impregnation. The fact is that these elements can be damaged by mold when moisture gets on them. Therefore, it is necessary to use special antifungal antiseptic compounds, for example, soak plywood with drying oil.

During impregnation, the solution is applied with a regular brush. The surface should dry well, after which the sheets can be used for laying on the floor. Additionally, it is recommended to varnish the plywood. This is not necessary, but the resistance to decay and strength will increase significantly.

Stage 5. Plywood sheet mounting technology

There are many different nuances here. For example, plywood can be laid directly on a plank floor, on a concrete screed and on pre-installed joists. If the third option is chosen, then when laying the logs, plates for alignment are necessarily placed under them.

On any surface, a gap of 3 mm is required between the sheets. This is necessary so that the surface remains flat during deformation. The best way to fix the plywood should be selected: for a wooden floor or when placing plywood on logs, only self-tapping screws are used, and for a cement-sand screed - glue and quick-assembly dowels (additional fastening).

If plywood sheets are mounted on a concrete screed, their surface is degreased and cleaned. A primer is used to increase adhesion. Only after that, a uniform adhesive layer about 3 cm thick is applied to the sheets. When the entire flooring is glued to the surface, you should wait until the glue is completely dry. After that, the plywood, as described above, is additionally fixed with a self-tapping dowel in increments of 15-20 cm.

Stage 4. Cosmetics

The final stage in the installation of a rough plywood flooring for linoleum is to seal the joints in the joints between the sheets with a spatula. For this purpose, as a rule, wood putty is used. After it dries, the surface should be leveled: for this, the joints are manually sanded with sandpaper. You can use a sander. Next, linoleum is laid.

Specialization: Master in the construction of plasterboard structures, finishing works and laying floor coverings. Installation of door and window blocks, decoration of facades, installation of electrical, plumbing and heating - I can give detailed advice on all types of work.

If you decide to cover the linoleum in the room, then the primary attention should be paid to the device of a high-quality and solid foundation. If the base is poorly prepared, then the life of the coating will be much shorter, so understand this issue as best you can in order to avoid mistakes. We will tell you which plywood to choose and deal with the main features of the workflow.

The main types of plywood and its features

As for the material discussed in our review, it is important to understand that the quality of the foundation depends on the right choice, so you should not buy anything, it is better to clearly understand which option is better in a given situation.

Types of products

Due to the fact that some time ago there were simply no alternatives to plywood, manufacturers produced a wide range of different types of plywood.

Let's list the main ones:

  • Packing option was used and is still used for the assembly of various containers. It is rarely used these days due to the proliferation of cheaper materials;
  • Structural plywood it is used for the construction of the framework of buildings, as well as for cladding various surfaces. This option is distinguished by increased strength indicators and large thickness;
  • Furniture Sheets can be different, for back walls, shelves and other elements that are not visible, the usual version can be used. But there is plywood with a laminated surface, it is much more resistant to abrasion and can have a different structure, because different types of film are used for finishing;
  • Construction plywood- the most widespread and demanded option, which is intended for use for a variety of purposes in the construction of houses and finishing works. It is also great for use as a base for linoleum.

Plywood for linoleum must meet certain quality and safety standards, therefore all products are marked in a certain way.

In our case, you can use the following brands:

  • FC - for this type of plywood, a carbide composition is used, which provides good moisture resistance. This option has a minimum content of substances that can have a negative effect on human health, therefore it is widely used in interior decoration;

  • FSF - this type of product is characterized by such an indicator as increased moisture resistance, since phenol-formaldehyde glue is used in the manufacture. This option should be used with caution, since in formaldehydes, when exceeding a certain concentration, they have a negative effect on human health;
  • FBA - plywood, which is glued together with albuminocasein glue, this composition is absolutely safe for human health. As for the shortcomings, the main thing is the low resistance to moisture, if you have high humidity in the room, then this decision is immediately excluded;
  • FB is the most durable and reliable option with excellent resistance to moisture and other adverse influences. This is due to the use of a bakelite-based adhesive. Such material can be used in rooms with the most difficult operating conditions;
  • FSF-TV, the list cannot be considered complete without considering this type of product. It differs from ordinary FSF plywood in that the material is treated with a special compound, which provides excellent resistance to combustion, this ensures increased safety of the entire structure.

Grade of material and other important indicators

In addition to the purpose and brand, plywood for linoleum flooring has a number of characteristics that you should be aware of. We'll start with the grade, there are four main options:

First grade The products of this grade are of the highest quality, there are no flaws on the surface, the sheets are processed with high quality and can be used as an independent coating
Second grade May have minor flaws on the surface, the number and size of which are specified in the relevant documentation. This option is also quite attractive and can be used as a stand alone decoration.
Third grade This grade has much larger tolerances regarding knots, cracks and delamination on the surface, therefore it is used exclusively as a material for the construction of foundations and hidden parts of structures.
Fourth grade As for the fourth grade, all sheets that have significant flaws and damage are included in it. The price of this option is the lowest, but be prepared for the fact that the quality will not be the best.

It is worth noting one very important factor - a plywood sheet has two sides and each can have its own grade. This is due to the fact that higher requirements are always imposed on the front side, while the wrong side may have certain flaws, the main thing is that they do not affect the strength and reliability.

For use as a substrate for linoleum, the 3/3 or 3/4 grade option is excellent, since the sheets are still not visible, and most importantly, strength, not appearance. In addition, the lower the grade, the lower the cost, and spending extra money for quality, which in fact does not matter, is at least unreasonable.

Another important indicator that cannot be ignored is the moisture content of the material. It should be 12-15%, this is a normal value, which ensures the stability of the base and the minimum probability of deformation after laying and fixing the elements.

The emission class shows the formaldehyde content in the material, this indicator should be taken into account when using plywood indoors. There is a recommendation here - if you do the work with your own hands, then when purchasing the material, choose only the E1 class, since it contains less than 10 mg of formaldehyde per 100 g of material and meets the highest safety standards for human health.

To be sure of the quality of the material, be sure to ask the seller for a quality certificate for plywood, both the brand and the emission class must be indicated there.

As for the standards according to which plywood is produced, the main documents are GOSTs, they may be different depending on the type of products and their purpose. The most important and demanded of them is GOST 3916.1-96 "General purpose plywood".

One of the most important criteria is the thickness of the plywood for the floor under the linoleum, it depends on how reliable the base will be and what loads it can withstand. In our case, options with a thickness of 12 to 18 mm will be ideal, it is this range that provides high strength and reliability. As a last resort, you can lay two layers of thin plywood, but remember to offset the seams for maximum reliability.

As for the sheet sizes, the following configurations can be found on sale:

  • 1220x1220;
  • 1270x1270;
  • 1475x1475;
  • 1525x1525;
  • 1220x1525;
  • 1270x1525;
  • 1350x1525;
  • 1475x1525.

Any of the configurations is suitable for work, it all depends on what is available in the retail network.

Plywood can be from hardwood and softwood, there is not much difference in our case, so choose the option that is available in the retail network. There are a lot of manufacturers, it makes no sense to consider them, since the quality is about the same.

As for the price, a standard sheet of 1525x1525 grade ¾ will cost you from 450 to 700 rubles apiece.

Let's briefly figure out how to lay plywood.

The instructions are presented in the form of a diagram, and below each item is described in more detail:

  • First of all, the surface is cleaned of dirt and debris, after which it is necessary to check the plane using a level. If there are significant differences on it, that is, there are two alignment options: either pour the screed, or lay the plywood on the logs, the choice of a specific solution depends on you;

  • It is important to understand that plywood is a material made of wood, therefore, with changes in temperature and humidity, the parameters may change. Before using the sheets, they must lie in the room for a while so that their moisture is stabilized;

If the plywood was stored in conditions close to yours, then it is enough for it to lie in the room for a day.
In cases where the material was in a warehouse, where conditions differ from the premises, it is better to put it in a room for 5 days, and if the sheets are deformed, then let them lie under pressure for at least 10 days.

  • Laying the whole elements is not the best option, it is recommended to cut them into smaller pieces in order to minimize deformation processes. So a standard sheet 1525x1525 is cut into 4 parts;
  • Now let's figure out how to impregnate plywood under linoleum, it is best to use antifungal compounds, since most often the material is damaged by mold when moisture gets in. The solution is applied with a simple brush, the surface must dry, after which the sheets can be used;

  • Next, you need to fasten the elements, there are many nuances. Firstly, the gap between the sheets should be 3 mm so that the surface remains flat during deformation, and secondly, you need to choose the optimal fixation method. For concrete, quick-assembly dowels are used, and self-tapping screws are used for;

  • Seams are sealed last, acrylic sealant can be used for this, it is inexpensive and easy to apply.

Output

Plywood is an excellent solution as a base for linoleum, because this material, in addition to strength, provides good heat and sound insulation. The video in this article will tell you additional information on this topic, and if something is not clear to you, ask questions under the review.

If you want to express gratitude, add clarification or objection, ask the author something - add a comment or say thank you!

Linoleum flooring as a flooring is one of the most economical ways to form It also has good appearance. Its only drawback is its thickness, which does not allow it to independently cover even the smallest irregularities of the rough surface. Therefore, before laying the material, it is necessary to level the floor. Very often builders perform floor leveling with plywood under linoleum.

Advantages

The use of such a wooden base has a number of advantages:

  • the formation of a single flooring that does not acquire relief over time;
  • there is no need to dismantle the old coating;
  • the cost of rough work is removed;
  • low material cost;
  • the use of moisture-resistant types of plywood, which makes a similar method available for the bathroom, bathroom and kitchen.

Material selection

In order for the final result to be pleasing to the eye, it is necessary to choose the right rough finish. The thickness of the sheets should be between 10-22 mm. Plywood of 10 mm is the minimum acceptable value for such sheets, but it is extremely rare to use it. After all, it may not withstand a significant load. When choosing the thickness of the material, you need to remember the passability of the room and the weight of the furniture that is installed. The stronger the load, the more you need to choose the thickness.

It is highly recommended to give preference to moisture-resistant wood, which in humid rooms will not deform and change its shape. Although linoleum does not allow water to pass through, the joints and seams between the canvases remain weak points.

Instruments

Why cover:

1. Excellent dedusting of the surface, due to which particles also adhere to the floor, and a stronger adhesion is formed.
2. It has the ability to penetrate deeply into the base, which gives the concrete special strength.

Layout and adjustment of plywood

Sheets must certainly have a rectangular or square shape. Most often, plywood 1525x1525 in 10 mm is adjusted after 2 days from the date of delivery of the material to the object. This is done in order for the flooring to acclimate to the current room humidity and temperature conditions. If you follow the technological processes, then the plywood sheets should be laid in squares with overlapping joints and offset. The size of the blanks starts from 60 × 60 cm and more. The distance between the wall should remain 8-10 mm.

It is necessary to cut plywood in such a way that the floor area is filled to the maximum with whole canvases. Before starting cutting, it is recommended to draw up a diagram of their location. For preparatory cutting work, it is advised to use After a rough grinding is performed to remove small roughness.

Fixing sheets

1. The originally prepared material must be treated with an antiseptic and varnished. This step is optional, but it increases strength and adds resistance to decay.
2. The surface is cleaned and then degreased. You can also use a primer for this purpose.
3. Next, a 10 mm thick plywood sheet is fixed to the glue layer. Later, the same procedure is repeated with all the details.
4. After drying, the material is additionally fixed with self-tapping screws.
5. All gaps that have formed must be closed with wood filler.
6. Next, the joints are sanded with sandpaper.
7. Linoleum is laid out.

Preparatory work

The most popular material for leveling the floor is birch plywood. This raw material has good environmental performance and affordable cost. For alignment, plywood sheets 1525x1525 and 10 mm thick are selected, since such dimensions are the most popular.

If the parts will be laid on top of a concrete screed, experts recommend that it be pre-waterproofed with a solution or plastic wrap.

When that plywood is laid out both into logs, and without them. Initially, it is necessary to cut the plywood into comfortable sheets. At the time of attachment, it is required to leave small gaps to compensate for thermal expansion. And also between the plywood and the wall, you need to leave a gap. After laying it, the surface is treated with any primer.

Installation instructions

There are two types of mounting linoleum on plywood.

1. Glueless - after the plywood base is prepared, the stage of laying the coating follows. For rooms from 12-15 square meters, this method is optimal. But if the room has increased permeability, then it is better to give preference to the second method. Since it is already known about the method of laying plywood under linoleum, it is necessary to figure out how to lay out the coating efficiently and with maximum evenness. To do this, you need to adhere to the following algorithm:

  • after purchase, the material must be left indoors for several days for acclimatization;
  • the purchased roll is rolled out in another room, the area of ​​which will be larger than that of the declared one;
  • in accordance with the measurements, it is required to cut out a fragment with a margin of 50-100 mm on each side;
  • then the prepared piece is laid out in the room so that there are identical protrusions of the stock;
  • starting from the center, the surface is leveled towards the edge;
  • with a sharp clerical knife, cut off excess material (you need to retreat from the wall 1 cm);
  • for fixing, it is required to use skirting boards, and a steel strip in the form of a nut must be placed on the threshold.

2. Adhesive - means fixing the coating with adhesive mixtures. Initially, the material must also be trimmed in accordance with the parameters of the room. For these purposes, it is recommended to use only a sharp knife. Linoleum is laid out and its compliance with the shape of the room is checked. Then half of the flooring is pulled back and glue is applied to it. For this, a special grater or a toothed spatula is used. Then you need to wait as much time as indicated in the instructions. After that, the material is laid out on the surface and well leveled. The same is required to be done with the other half.
As the masters tell in their reviews, if plywood is laid on the floor under the linoleum, then when choosing an adhesive material, it is better to focus on PVA or formulations with a water base. Indeed, during operation, there is a possibility of plywood lagging. As a result, the material will bulge.
3. Another quick option for attaching linoleum is to use double-sided tape. Among the main advantages of the provided method, it should be noted:

  • cheapness and ease of work;
  • ease of implementation;
  • such linoleum is easier to dismantle than one that is fixed to an adhesive base;
  • reliable fixing of the coating.

Double-sided tape is required to be glued to the plywood floor around the entire perimeter of the room. It is also recommended to apply the strip to the joint areas.

Many newcomers to construction are wondering whether plywood is needed for linoleum. Experts almost unanimously give an affirmative answer in this case. Indeed, thanks to this manipulation, it is not necessary to level the surface before laying the material. Also, professionals provide practical advice to help simplify the process.

1. Before starting work, linoleum must be in the room for at least one day, and preferably two. Thanks to this maneuver, the flooring will get used to the temperature regime of the given room.
2. In the area of ​​doorways, batteries, the material must be laid very carefully, since there it must adhere closely.
3. After the flooring is completed, it is recommended to leave it alone for several days, and only after this time, start operating it.
4. At the time of trimming linoleum in areas near the wall, it is required to leave a little margin, since after laying it may shrink slightly.
5. In order to fix the covering near the doorway, it is advisable to use double-sided tape.
6. Before you start trimming linoleum, you need to align it from the inside, and then twist it into a roll.
7. There are two main ways to connect several sheets of material together:

  • Cold welding method - prepared sheets are installed with an overlap, and then, using a knife, the sheets are cut off at the junction. It is very important to use only a sharp knife for this, since you will need to cut two blades at once. After this procedure, double-sided tape is placed under them, and they are fixed on it. Next, it is required to apply liquid glue to the surface, which will seal the ends together.
  • In order to make hot welding, it is recommended to use a construction hair dryer, which melts a special cord laid at the joint. After this procedure, everything needs to be smoothed out with a trowel.
