Laying plywood on logs under linoleum. Plywood under linoleum: leveling the floor, choosing a material, installing a log and laying sheets. Option for rough coating with plywood sheets directly on the adhesive

You can lay linoleum on plywood without much effort, but the floor surface must be flat so that the coating is not damaged over time. You can level a wooden floor using putty or self-leveling compounds, but this method will take a lot of time and certain skills will be required to achieve a quality surface.

You can quickly and relatively inexpensively level a wooden floor with ordinary plywood. Plywood can be laid both on a cement screed and on logs. This method will allow you to get a perfectly flat and high-quality surface, on which you can easily lay linoleum or any other floor covering in the future.

Main properties of plywood

The thickness of plywood under linoleum must be at least 12 mm.

Plywood is several layers of thin wood glued together. With its help, you can level not only the floor, but also any other surface. It is a durable environmentally friendly material that can last a long time. The surface of the plywood is even and smooth, able to withstand temperature fluctuations in the room.

When using plywood for the floor, the load falls on the entire sheet, which prevents the surface from sagging. Sheets of plywood are closely adjacent to each other, which does not allow rodents or insects to penetrate under them. If necessary, plywood sheets can be easily changed. Plywood under linoleum will increase the heat and sound insulation of the floor.

Selection and preparation of plywood

Plywood for linoleum must be chosen responsibly so as not to receive negative surprises in the future. The plywood thickness must be at least 20 mm. It is desirable that the plywood be moisture resistant and treated with antifungal antiseptics. If you purchased raw material, be sure to soak the sheets yourself with drying oil or moisture-resistant stain.

For ease of installation, plywood sheets are cut into squares, based on the size of your room. This can be done with a special jigsaw or buy ready-made squares. Then the squares must be placed on the floor without fixing in order to fit them in size and number them. Before that, we get rid of old baseboards and debris on the floor. Lay the plywood with a shear, using the principle of laying a brick wall, to increase the strength of the coating. Be sure to leave technical gaps under the walls up to 2 cm and between squares up to 0.5 cm, so that during expansion there is no friction between the plywood sheets.

How to lay plywood on a concrete screed?

First you need to check the floor level. The maximum allowable discrepancy must not exceed 2 mm. Then the base is carefully prepared. With the help of a vacuum cleaner, all debris and dust are removed, the room is de-energized, and then the surface is washed with warm water. After drying, you need to cover the concrete screed with a thin layer of bituminous varnish or putty.

Ideally, after drying, a thin waterproofing film should be laid. It is laid with a slight stretch, fixed at the edges with special glue. After the glue has set, you can start laying plywood.

Figure 1. All fitted sheets are numbered according to their layout.

First, identical squares are prepared. After that, you need to lay plywood in a draft version. That is, do not fix it to the floor, but simply put it the way you want to see it in the future (Fig. 1). At the same time, do not forget that the squares must be laid with overlapping seams.

After numbering, you can already make the final installation. The best option is to fasten plywood with “liquid nails” or special glue for this purpose. Bustilat can also be used. But the use of self-tapping screws in this case is undesirable. After setting, the floor under the linoleum is ready!

How to lay plywood on a wooden floor?

Laying plywood on a hardwood floor surface under linoleum is very similar to laying on concrete. But at the same time, there are some subtleties that must be observed so that in the future the coating does not deteriorate and lasts for a long time. Before work, be sure to de-energize the room.

First you need to replace those wooden boards that have become unusable. After that, the surface is checked with a level and knocked out with a hammer in places of protrusion. With the help of a vacuum cleaner, the floor is freed from dust, and then thoroughly washed.

It is very important to wait until the floor is completely dry. Therefore, it is advisable to check the level of humidity by applying a film for a day. In the absence of condensate after removal, you can proceed to the next stage of work, in which the surface is covered with a primer with the addition of an antiseptic. If there is condensation, you need to dry the floor more. For this purpose, you can use a regular hair dryer or put a heater in the room. Just do not leave the device turned on while you are away from home! After all, dry wood ignites very well.

Approximately two days after the complete absorption of the primer and the final drying of the surface, you can begin to fasten the plywood. To do this, the sheets are again cut into squares, as in the case of their laying on a concrete screed, after which they are laid in a draft version. Be careful to keep the gaps.

Fastening is carried out on bustilat or self-tapping screws. It is better to combine these two methods. Hats of self-tapping screws must be well recessed. After finishing work, the plywood is cleaned of dust and covered with a thin layer of wood varnish. Now you can safely put linoleum on plywood!

So, now you are familiar with the basic properties of plywood and the intricacies of laying it under linoleum both on a concrete screed and on a wooden floor base.

If you follow these basic rules, then after laying linoleum, the floor will not cause you any problems. And in the room there will be a noticeable feeling of warmth and comfort.

Linoleum flooring as flooring is one of the most cost-effective shaping methods. It also has good external performance. Its only drawback is the thickness, which does not allow it to cover even the smallest irregularities of the rough surface on its own. 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 several 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 price of the material;
• 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 please the eye, it is necessary to choose the right rough coating. The thickness of the sheets should be in the range of 10-22 mm. Plywood of 10 mm is the minimum allowable value for such sheets, but it is recommended to use it extremely rarely. After all, it can not withstand a significant load. When choosing the thickness of the material, you need to remember the patency of the room and the severity of the furniture that is installed. The stronger the load, the more you need to choose the thickness.

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

Tools

Why cover:

1. Excellent dedusting of the surface, so that the particles also adhere to the floor, and a stronger bond is formed.
2. It has the peculiarity of penetrating deeply into the base, which gives the concrete a special strength.

Marking and fitting plywood

Sheets must necessarily have a rectangular or square shape. Most often, plywood 1525x1525 in 10 mm is adjusted after 2 days from the moment the material is delivered to the facility. This is done in order for the flooring to acclimatize to the current humidity and room temperature conditions. If you follow the technological processes, then plywood sheets should be laid in squares with overlapping joints and offset. The size of the blanks starts from 60 × 60 cm or more. The interval 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 work, cutting is recommended to be used. After rough grinding is performed to remove small roughness.

Fixing sheets

1. Initially prepared material must be treated with an antiseptic and varnished. This step is optional, but it increases strength and adds rot resistance.
2. The surface is cleaned and then degreased. You can also use a primer for this purpose.
3. Next, a sheet of plywood 10 mm thick is fixed on the adhesive 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 cracks that have formed must be closed with wood putty.
6. Next, the joints are polished 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 characteristics and affordable cost. For alignment, sheets of plywood 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 pre-waterproofing it with a mortar or plastic film.

When the plywood is laid out both on logs and without them. Initially, it is necessary to cut plywood into convenient sheets. At the time of fastening, 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 installation of 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 traffic, 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 with high quality 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 ​​\u200b\u200bwhich will be larger than that of the declared one;
• in accordance with the measurements, it is required to cut 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;
• excess material is cut off with a sharp clerical knife (you need to retreat 1 cm from the wall);
• for fixing, you need to use skirting boards, and you need to place a steel strip in the form of a threshold on the threshold.

2. Adhesive - means fixing the coating with the help of adhesive mixtures. Initially, the material must also be cut 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. Next, half of the floor covering is moved away and glue is applied to it. For this, a special grater or a toothed spatula is used. Then you need to wait such an amount of time as indicated in the instructions. After the material is laid out on the surface and well leveled. The same must be done with the other half.
As the masters say in their reviews, if plywood is laid on the floor under linoleum, then when choosing an adhesive material, it is better to stop at PVA or water-based compositions. Indeed, during operation, there is a possibility of lagging behind plywood. As a result, the material will swell.
3. Another quick option for attaching linoleum is to use double-sided tape. Among the main advantages of the proposed method, it should be noted:

• cheapness and ease of work;
• ease of implementation;
• such linoleum is easier to dismantle than one that is fixed on an adhesive base;
• secure coverage.

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 on the butt sections.

Many beginners in construction are wondering if 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 give practical recommendations that will help simplify the process.

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

• Cold welding method - the prepared sheets are overlapped, 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 canvases at once. After this procedure, double-sided tape is placed under them, and they are fixed on it. Next, you need 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 building hair dryer, which melts a special cord laid at the junction. After this procedure, everything needs to be sorted out with a trowel.

Installing linoleum as a floor covering is the most economical and at the same time good looking way to create a finished floor. The only significant drawback of linoleum is its small thickness, which does not allow it to cover even minor irregularities in the rough surface. Before you start laying linoleum, you must first level the floor.

In this case, the fundamental role is played by strength characteristics, respectively, the appearance of the material does not play practically any significance. The best solution would be to use plywood sheets (for example,) - this is a reliable and at the same time not very expensive material that is ideal for this purpose. The price of plywood is quite affordable, and the degree of leveling obtained as a result of the work performed is at a high level.

Do-it-yourself installation will allow you to significantly reduce the cost of hiring professionals - installation costs average about 30 - 40% of the total cost of the material. Our step-by-step instructions will help you level the subfloor with plywood with your own hands - it will describe the main features of this process.

Floor leveling with plywood

Material selection

The thickness of plywood under linoleum should be at least 12 mm - thinner sheets will have to be covered in two layers, which will result in increased costs. You should also choose products from hardwood veneer, since coniferous counterparts, although they have greater moisture resistance, are several times inferior in strength, which is unacceptable in this case.

Pay attention to the labeling of the purchased plywood - most products are made with phenol and formaldehyde, which is not very healthy. FBA plywood is considered the safest, which is impregnated with natural compounds and is an environmentally friendly product. Also, products with the FC label are relatively safe. Plywood FSF and FB have the highest toxicity.

Installation lag

To create a perfectly flat surface, it is necessary to install a log that will absorb bumps and create space between the concrete and plywood. As a log, boards with a thickness of at least 5 cm and a width of 10 -15 cm are suitable.

Note! Plywood on a wooden floor under linoleum is an extra waste of money that will not bring the desired result, since if the differences are small, then it is much more expedient to treat the surface with a grinder. If the boards are in a very deplorable state, then it is better to disassemble it and cover it with plywood again.

• The surface is completely cleared of stones, sand and other secondary elements that may interfere with the installation of the supporting structure;
• Using the hydraulic level, marks are made on the wall around the entire perimeter of the room. Then, if necessary, the marks are lowered to the required level, and the entire perimeter of the room is outlined according to the marks made, connecting them into one line - this way you will get the ideal level of the future floor;
• Before proceeding with the installation of the log, it is necessary to lay a shock-absorbing layer that will prevent creaking and knocking when the floor is loaded. For this purpose, you can use a synthetic winterizer or similar materials;

• According to the marks made, extreme logs are installed - to bridge the gap between the concrete and the base board, wooden bars are used, the thickness of which will cover the existing gap. The leveling elements must be screwed to the joists with screws - the more often they are located, the less deflection the structure will undergo.
• A building thread is stretched between the installed and fixed extreme lags, which will serve as a guide for intermediate elements - the distance between them should be about half a meter. They are mounted in the same way as in the above case.
• After the longitudinal logs are installed, the transverse lathing is fixed - their location is adjusted to the edges of the sheet.

plywood flooring

After carrying out the above steps, you should get a structure in which all elements are at the same level horizontally - you can proceed directly to the skin.

For this purpose, you can use both solid sheets and parts sawn into equal rectangles. When sawing, it is important to maintain the correct geometric proportions, otherwise it will be difficult to combine joints.

First of all, a preliminary layout is carried out - the floor area is measured, then the sheets are sawn to the obtained dimensions and visually adjusted. When fitting and laying out, it should be noted that the plywood sheets should be staggered, that is, the connecting seams should not depend on each other.

An important point is the obligatory presence of an expansion joint in places where the plywood will adjoin the wall - the gap should be at least 6 cm.

Plywood on the floor under linoleum is fixed with wood screws. Since the surface will be covered with linoleum from above, the caps of the fixing elements must be heated.

To do this, a drill pre-drills shallow holes corresponding to the diameter of the screw head. After fixing, the attachment points are puttied with the appropriate composition.

Note! The fixation of the sheet is carried out gradually - it is undesirable to fasten the sheet at the same time in all corners, as this can lead to its deformation and a loose fit to the base.

Outcome

Linoleum floor plywood is one of the most economical and at the same time effective surface preparation methods - at a low cost, you will get a fairly good result.

Using plywood as a subfloor helps to quickly and accurately level any floor covering. Installing linoleum on a plywood floor is a great option for finishing the floor, as this process does not take much time and is easy to perform. However, the installation of linoleum on a plywood base has its own characteristics and requires compliance with a certain technology for its implementation. We will consider how to put linoleum on plywood further.

Linoleum - characteristics and advantages of the material

The popularity of linoleum is primarily due to its availability, good performance and low cost. Linoleum is the most economical and popular floor covering, which has good thermal insulation characteristics.

In addition, the variety of patterns of linoleum allows you to use it in any room. Due to this, linoleum has a very wide scope. It is used for finishing the floor both in residential and public, and in industrial premises.

Linoleum perfectly imitates wood, stone, glass, ceramics, tiles and other materials. Thanks to this, it fits into any type of interior. Among the main advantages of linoleum, we highlight:

• easy installation - installation of linoleum does not require special equipment or special skills to work with it, even one person can install linoleum;
• ease of operation and maintenance - this material is well cleaned of dirt, so its use is relevant in rooms with high traffic, it is enough to use warm soapy water to clean linoleum;
• does not need to apply protective compounds, as parquet;
• soft, but at the same time durable and elastic, these qualities give linoleum high tensile strength and resistance to mechanical damage;

• due to the fact that the service life of linoleum is several decades, this material is practical and durable;
• moisture resistance, allows you to mount linoleum in rooms with medium and high levels of humidity, such as a kitchen, bathroom;
• another advantage of linoleum is its resistance to acid and aggressive chemicals;
• linoleum has high heat and sound insulation characteristics;
• linoleum has a low level of slip, thanks to this, people who move along it are safe, so linoleum is widely used for laying in the kitchen, in the gym or in public buildings;
• linoleum is perhaps the most diverse material in terms of colors, it imitates other types of coatings and is distinguished by diverse patterns and the most unusual colors;
• with the help of linoleum it turns out to equip the underfloor heating system;
• affordable cost is the first factor that ensures the popularity of this finishing material.

Linoleum has a lot of advantages, but it still has certain disadvantages:

• for laying linoleum, a perfectly even base is required, a plywood subfloor is ideal;
• installing heavy furniture on a linoleum surface leads to the formation of dents on it.

However, if we compare the advantages and disadvantages of this material, it is obvious that it has much more advantages.

Varieties of linoleum for laying on plywood

Among the main types of linoleum, there are:

1. Household version of linoleum - a foamed polyester base is used for its manufacture, a strip of such linoleum in thickness is from one to four millimeters. However, this type of linoleum has a complex structure. Among its advantages are:

• variety of colors;
• high level of softness;
• moisture resistance;
• easy styling;
• affordable cost.

However, if this type of linoleum lends itself to high operational load, then its service life is about three years. This material is unstable to heavy weight, therefore, due to its softness, it is prone to the formation of dents. This version of linoleum is recommended for use in residential premises.

2. Commercial variant of linoleum - it is distinguished by high wear resistance and long service life. Great for installation in offices or salons, as it involves applying any kind of emblems or drawings to it. There are two options for such linoleum:

• homogeneous type linoleum;
• linoleum heterogeneous type.

The first option differs in thickness from one and a half to three millimeters. It has a monochromatic pattern, it contains components in the form of limestone, talc and kaolin. A special polyurethane coating is applied to the surface, protecting it from mechanical and external influences. Once every six months, this coating needs to be sanded.

The second version of linoleum - heterogeneous, is highly versatile. It has a multilayer structure, it is based on the use of fiberglass. To impregnate the front part of the linoleum, PVC paste is used, then a pattern is applied to the linoleum, which is fixed with another layer of polyvinyl chloride. On the inside of the linoleum, a substrate is laid, made of fabric, jute or foamed polyvinyl chloride. This linoleum does not need special care and has a long service life.

3. Semi-commercial type linoleum - similar to the domestic type of linoleum, however, it has a higher protective layer thickness, about 0.6 mm. The scope of its application is connected with public and walk-through premises.

In relation to the type of materials used in the production of linoleum, it is divided into:

• synthetic type linoleum;
• natural linoleum.

The first option is easy to care for, moisture resistant, good soundproofing characteristics. However, this linoleum has one drawback - the use of synthetic resins in the process of its production.

The natural version of linoleum is environmentally friendly to human health. It is resistant to wear, deformation and abrasion. For the manufacture of modern natural linoleum, linseed oil, resin, jute fabric and natural-based dyes are used. To ensure the protection of linoleum, a polymer coating is applied to it.

Due to the presence of linseed oil in its composition, linoleum has bactericidal characteristics, in addition, such linoleum has a high level of fire safety. It is easy to clean, does not change color under the influence of ultraviolet radiation. This linoleum is not used in places with increased operational load or in rooms with a high level of moisture.

The technology of laying linoleum on plywood: preparatory work

Plywood flooring on a wooden base is carried out in order to completely level it. If this is not done and linoleum is laid on an uneven floor, then soon it will take its shape and become uneven too. The end result is an aesthetically pleasing finish.

Even if the wooden floor is even, it can creak, and laying plywood on it will avoid this unpleasant process. Before starting work, you should determine the place where the logs are installed, if any. To do this, one board is torn off the floor. Then, with the help of long self-tapping screws, the floor begins to scroll. Please note that none of the boards should hang out. Self-tapping screws should be of such length as to ensure a snug fit for each board. The distance between the concrete floor and the screws should be at least ten centimeters. To fill the cracks, wooden wedges or mounting foam are used.

The most popular floor leveling material for laying linoleum is birch plywood. For its manufacture, veneer layers are used, glued together. This material has an affordable cost and good environmental performance. In order to level the floor with plywood, choose a material that is about one centimeter thick. The price of the material depends on its thickness and the wood used in the process of its manufacture.

After checking and preparing the subfloor, the plywood laying process follows. If plywood is laid on top of a concrete screed, it is recommended that it be preliminarily waterproofed with a plastic film.

Plywood is laid on the floor both on logs and without them. Before starting work, you should cut the plywood into sheets convenient for fixing on the floor. Large sheets are most conveniently cut into four parts. Leave small gaps between the sheets to compensate for their thermal expansion. In addition, a gap of 1-1.5 cm is also left between the wall and plywood. Fix the plywood in a checkerboard pattern, after laying it, treat the floor with a primer or primer. Using the rule, check the base for evenness.

How to lay linoleum on plywood: how to lay linoleum

There are two options for laying linoleum on plywood:

1. Glueless installation of linoleum - after the preparation of the plywood base, the process of linoleum flooring follows. If the area of ​​​​the room is from twelve to fifteen square meters, then this installation method is the most optimal and suitable.

However, if the room has increased traffic, it is still recommended to use the second method. If you lay linoleum in a large room using a glue-free method, then over time, there is a risk of its deformation and swelling. In order to lay linoleum on a plywood base with high quality and with maximum evenness, follow a series of steps:

• after buying linoleum, leave it indoors for at least a day to acclimatize it;
• roll out the roll in another room, the area of ​​\u200b\u200bwhich is larger than the one in which it will be laid;
• in relation to the measurements of the room, cut out a piece of linoleum for laying, leave a margin of 50-100 mm on each side;
• roll out the cut out fragment in the room so that its stock extends beyond the walls evenly from all sides;
• starting from the central part of the room, level the linoleum moving towards the edges;
• using a sharp clerical knife, cut off the excess linoleum, stepping back one centimeter from the wall;
• to fix linoleum on the floor, use skirting boards, and install a steel rail in the form of a threshold on the threshold.

2. The second option for laying linoleum will tell you how to glue linoleum to plywood, as it involves gluing linoleum to the floor surface.

At the beginning of work, linoleum is also cut in relation to the parameters of the room. For these purposes, use a sharp knife. Lay the linoleum sheets on the floor, check their compliance with the shape of the room.

Bend half of the linoleum, grease it with glue. To apply the adhesive, use a special grater or a toothed spatula. Next, wait as long as indicated in the instructions for the glue that is applied to the linoleum, lay the linoleum on the floor, carefully leveling it. Watch for the absence of air bubbles on the glued sheet of linoleum. Do the same with the second half of the linoleum, if you plan to mount several linoleum sheets in the room, then they are overlapped, and then cut with a knife and welded using the hot or cold welding method and special equipment.

Tip: When choosing an adhesive for laying linoleum on a plywood base, you should not stop at PVA glue or water-based compounds. Since during the operation of linoleum, there is a risk of plywood settling and swelling of the material. It is better to give preference to compositions intended for wooden surfaces.

Another option for sticking linoleum to the surface is to use double-sided tape. Among the advantages of this method of installation should be noted:

• ease of implementation;
• ease and cheapness of work;
• such linoleum is easier to remove than glued with glue;
• reliable fixation of the coating.

Double-sided tape is glued to the plywood floor, around the perimeter of the entire room. In addition, adhesive tape must be glued on the butt sections.

1. Before starting work, linoleum should be in the room for at least a day, and preferably two, so it will get used to the temperature and humidity conditions of the room.

2. Special care should be taken when laying linoleum near radiators, doorways and niches, it must fit closely to them.

3. After laying the linoleum, if possible, leave it for one or two days, and only after the specified period, start using it.

4. When cutting linoleum in areas near the walls, leave a little margin, as linoleum shrinks slightly after installation.

5. To fix the linoleum near the doorway, use double-sided tape.

6. Before cutting linoleum, turn it inside out and roll it up.

7. In order to connect two sheets of linoleum together, there are two ways:

• cold welding method - install sheets with an overlap and use a knife to cut off the linoleum at the junction, attention - use only a sharp knife, since you need to cut two sheets of linoleum at once, then apply double-sided tape under the sheets of linoleum, fixing them on it, apply to the surface material in the form of liquid glue, it will connect the ends together;
• with the help of hot welding, a construction hair dryer is used, which heats up a special cord, which is immediately laid at the junction and smoothed out with a special ironing board.

For those who have decided to choose linoleum as a floor covering, you need to know that the service life of the coating depends on the quality preparation of the base. Therefore, the preparation of the base must be given special attention. Linoleum plywood as a leveling material is ideal. Consider its advantages and disadvantages and styling features.

To understand what kind of plywood is needed for a floor under linoleum, you need to understand what kind of tasks are set for it. Usually with its help solve such problems:

• Base leveling;
• Warming and soundproofing;
• Raising the level of the floor.

But leveling with plywood is possible only with small height differences (up to 5 mm). Otherwise, a concrete screed is used.

Eliminate height differences before laying

In addition to leveling, plywood retains heat well and protects against noise. In addition, installation costs are negligible.

Functions

This material perfectly copes with the tasks of leveling any base at a low cost. When laying plywood to level the floor, the load when moving along it is distributed evenly. This is due to the fact that human weight falls on a whole sheet of plywood, and not on one or two boards of a wooden floor when laying under linoleum.

Spending a little more money on alignment can save you a lot more money on future repairs.

The benefits include:

• Low price;
• Distribution of load on the floor;
• Hides all irregularities, defects and holes in the floor;
• Durable and wear-resistant material;
• Excellent heat and sound insulation;
• No squeaks.

It cannot be argued that this construction coating is problem-free, which is a pleasure to work with. It also has the disadvantages listed below.

Plywood, which is laid on the floor under linoleum, like other materials, has disadvantages:

• Under the influence of moisture and chemicals can be deformed;
• There is a high probability of the appearance of mold, fungi, insects;
• The presence in some types of glue that releases toxic substances;
• High flammability of the material;
• A characteristic change in characteristics (expansion, contraction) with fluctuations in the microclimate.

Some deficiencies can be eliminated by applying special products to the coating, depending on the problem to be solved. To avoid mold, you need to know how to process plywood under linoleum. Usually, antifungal solutions are used for this, which are applied to the surface with a brush. Moisture-resistant material is used against moisture. To reduce flammability, wood material is treated with flame retardants.

When choosing plywood for leveling, it is necessary to focus on such parameters as: thickness, moisture resistance and formaldehyde content in the wood material.

A detailed encyclopedia about all its types, classes and division by type of wood.

To level the floor under linoleum, plywood is required at least 12-16 mm thick. In terms of moisture resistance, preference should be given to medium moisture resistance (FC) and increased moisture resistance (FSF).

According to the presence of formaldehyde in the composition, it is divided into classes E1 (10 mg per 100 g of wood) and E2 (10-30 mg per 100 g of wood). For apartments and residential buildings choose E1.
