With all the variety of methods used to create the base of the flooring, plywood for laminate wooden floor It is considered one of the most modern and technological solutions for arranging laminated floor coverings in residential premises.
Floor lamination technologies
The variety of laminate flooring solutions can be divided into two: large groups, differing from each other in the basis of the laminate itself:
- Rigid laminate - made on the basis of chipboard (chipboard) or fibreboard (fibreboard), involves laying on a pre-leveled surface or using leveling substrates. If laid on a pre-leveled surface, its curvature should not exceed 2 mm per linear meter. If the laminate is laid on special leveling substrates, they are able to compensate for unevenness to a large extent, and this depends on the thickness and material. As an example, a 5 mm thick polyurethane foam backing can compensate for unevenness of up to 3 mm per linear meter. Exceeding these values leads to excessive stress in the laminate joints.
- Flexible laminate, unlike the previous ones, i.e. hard laminates, has vinyl base, which allows it to be laid on a poorly prepared base that allows height differences of up to 5 mm. By appearance floor covering made from such material differs little from traditional solutions, but at the same time much stronger than them and absolutely moisture resistant.
Technology for laying laminate flooring on wooden floors
Design decisions related to laying laminate flooring on wooden floors will depend primarily on the condition of the floors themselves.
In any case, floor preparation work is preceded by diagnostics, during which the actual state of the wooden flooring is analyzed and a decision is made on methods for preparing and compensating for unevenness. In accordance with SNiP, the following gradation is recommended:
- New wood floors. It is assumed that they are laid out as required, i.e. appropriate treatment against fungi, etc. has been carried out. Height differences are checked, fastening nails or screws are recessed, and the cracks are filled with a special solution. If the unevenness of the flooring exceeds 2 mm per linear meter, additional measures are taken.
- Old wooden floors require disassembly to assess the condition of the joists and other structural elements. During repairs, it is recommended to turn the logs upside down, check their condition, and also minimize level differences. Remove worn elements and replace them with new ones. After this, the flooring is reassembled. Removed if necessary old paint, the floor is sanded mechanically.
- Sometimes a method is used in which a new floor is laid on top of the existing wooden floor at an angle of 90° (in a cross) - if there is confidence in the quality of the base (of course, if the height of the room allows).
Types of plywood
Laying plywood on a wooden floor is very affordable way renovation of the premises, since the industry produces enough a large number of types of this lumber. There are plywood made from coniferous species wood, and birch plywood.
Based on the degree of moisture resistance, plywood is divided into three categories:
- FOF - has the most low level moisture resistance, but little is used in its manufacture toxic adhesives;
- FC - plywood with an average level of moisture resistance, most suitable as a base for laying laminate;
- FSF is an increased level of moisture resistance, but toxic adhesives are used in the production of such plywood, i.e. It is not recommended to use it in residential premises.
In addition, according to quality (presence of inclusions, heterogeneity of composition, rottenness) plywood is divided into 4 grades. The most expensive is 1 (first). When creating a substrate on a wooden floor, it is quite acceptable to lay 3rd grade plywood. Plywood is produced standard size, in sheets 1.5 m wide. It is advisable to cut such a sheet right on the spot, based on cutting the sheet into 4 parts - for ease of transportation.
Plywood laying technology
The installation technology is described in detail in the relevant literature, but several fundamental points should be noted:
- On slats or directly on the floor - if the warping of the floor boards is insignificant, and the total height of the room allows it - plywood panels can be attached directly to the floor (plywood thickness - 10-18 mm). Otherwise, fastening is carried out through special slats, which are evenly placed on the base and thus level the surface.
- Thermal clearances are extremely important to avoid warping due to thermal expansion plywood backing. It is recommended to leave at least 8-10 mm between sheets, and distances from the walls - up to 15 mm.
- The plywood sheets are laid out on a wooden floor under the laminate with bandaging - a technique adopted for brick laying, which eliminates the formation of long seams, as well as corners where all four sheets meet. This solution minimizes the load on the locks of laminate structures.
- Fastening is carried out with self-tapping screws through pre-countersunk holes, allowing the heads of the screws to be recessed into the sheet.
- Final processing allows grinding the resulting surface mechanically to remove protrusions and focal irregularities.
Traditionally, it is used to level a concrete floor. cement strainer. But what to do if the floors in the house are wooden or you just don’t want to dismantle the old flooring in order to lay laminate flooring? In this case, the most the right decision There will be plywood under the laminate on a wooden floor.
If you are concerned about the question of whether it is possible to lay laminate flooring on plywood, then you are worrying in vain: of course, it is possible. Moreover, the technology for laying laminate on plywood is no different from laying it on a cement screed.
The basis for plywood can be not only a wooden floor, but also logs or the same screed. But in each case, the technology for laying it will be slightly different.
Which plywood to choose
The main question that arises when you want to make a covering from plywood: what should be the thickness of the plywood under the laminate?
It depends on the base on which it will be laid.
- If it is very smooth and durable, then a thickness of 8-10 mm is sufficient.
- If you have to lay gaskets, then its thickness should be at least 12 mm.
- You need to be especially careful about what kind of plywood is needed for the floor under the laminate if it is laid on joists. Since it will have to withstand serious loads, in this case you should choose a material with a thickness of at least 15-20 mm. Of course, the price of such plywood is higher, but you cannot save on it.
Laying plywood on a wooden base
Or self-leveling floors, but this is not always possible. And if you live in a house with plank floors or repairs need to be done in a very short time, laying plywood under the laminate will be the most optimal solution. You can watch the video or study the description below to see how this is done.
Laying on a wooden floor
The order of work will depend on the condition of the existing flooring.
Let's assume that we are dealing with the most difficult option: an old plank covering that requires preparation.
- Carry out an inspection: open the flooring and make sure that the joists and boards have not begun to rot. If this is not the case, the damaged elements will have to be replaced by first treating the logs with an antiseptic.
- Laying plywood on a wooden floor under laminate begins with its cutting and fitting. To do this, the sheets are laid out on the floor without securing them in order to determine their optimal location.
Note. If you look at the first photo, you will see that the sheets are laid with offset seams, and a small gap is left between them to allow the material to expand when temperature and air humidity change.
- First, whole sheets of plywood are laid so that they occupy the center of the room. After which pieces are cut out for laying along the edges. It must be remembered that the plywood should not touch the walls.
- Having found the optimal position of each sheet, number them and draw a layout diagram. After which the plywood must be removed to thoroughly clean the base from dirt, dust and sawdust formed during sawing.
- The plywood for the floor under the laminate is secured with self-tapping screws, the heads of which must be recessed.
During fastening, it is necessary to constantly monitor the evenness of the flooring using a two-meter strip. If necessary, pieces of fiberboard or other similar material are placed under the plywood for leveling.
Laying on joists
As mentioned above, plywood on the floor under the laminate, laid on the joists, must be of sufficient thickness to withstand the expected loads. The logs themselves must be treated with an antiseptic composition, regardless of whether they are laid on a concrete floor or on supports. It is advisable to treat the plywood itself with the same composition.
The installation technology is somewhat different from how plywood is laid on a wooden floor under laminate.
First of all, this concerns cutting: the dimensions of the sheets should be such that the joints fit on the joists and do not hang in the air. If there are already logs, then you will have to cut out the plywood in accordance with their location. If they are just to be laid, then the logs should be laid in accordance with the dimensions of the plywood sheets.
Important!
Long logs must be connected with short transverse jumpers at the joints.
Laying plywood on a screed
Floor slabs cannot serve; they need to be leveled with cement screed or special self-leveling self-leveling compounds. If the screed is made with high quality, then only you can decide whether you need to lay the laminate on plywood or you can do without it. But with plywood, the heat and sound insulation in the room will be better.
Instructions for preparing a concrete base for laying plywood are as follows:
- Check the moisture level of the screed by placing a piece of it on it polyethylene film and pressing its edges tightly to the floor. If after 3-4 days condensation does not appear on its inner surface, then you can start working.
Advice. When deciding which plywood to lay under the laminate, choose moisture-resistant one, since regular plywood may suffer from residual moisture in the screed.
- Next, the plywood is adjusted and cut, as in the case of a wooden floor.. After which the base should be thoroughly cleaned of dirt and dust.
- The next stage is priming the surface. Laying laminate flooring on plywood with your own hands must necessarily include this stage. A penetrating primer will give the screed additional strength, and it will not wear away under the coating, forming dust.
- The plywood, according to the drawn up diagram, is laid on the base and secured to the floor with self-tapping screws and dowels.
Conclusion
Before laying the laminate on plywood, it must be sanded to eliminate differences at the joints and cleaned of dust. After which you can begin laying the finished floor.
If the question arises about the upcoming leveling of the floor, the first thought that arises will be: cement screed. It doesn't always fit. What to do when the apartment has a wooden floor, reinforced with joists, but quite strong? What to do if there are no plans to dismantle the wooden covering yet, but there is a desire to lay a new, laminated one? In this case, the best solution would be to lay plywood. How to carry out installation and what the thickness of plywood should be for laminate flooring on a wooden floor will be discussed below.
Plywood is environmentally friendly, durable, helps increase thermal insulation, levels the surface and increases sound insulation. If you have not yet decided which plywood will help you level your floor better, then you can purchase material of category III or IV. This plywood is affordable and has been treated against moisture.
The method of installing plywood and its thickness are determined by the type of base on which it will be installed. When the base for laying is properly leveled, a thickness of plywood sheets of 10 mm is acceptable. If it is necessary to level the surface of the base using additional spacers, then a material with a thickness of at least 15 mm is selected.
A special requirement for the strength of the material is imposed in the case of laying plywood boards on logs. In this case, the sheets are subject to significantly greater load; plywood with a thickness of at least 18 mm is suitable.
How to lay laminate on plywood with your own hands
The entire floor area is covered with plywood under the laminate. Sheets, standard parameters which are often 1500x1500mm, are pre-cut with a jigsaw into 4 equal parts. They are laid out in a way brickwork, i.e. the sheets of the subsequent row are positioned with a shift relative to the previous one by approximately 30 cm. As a result of this installation method, we obtain the highest level of rigidity of the plywood layer.
These squares should be screwed to wooden floor not close to each other, but at a distance of 2-3 mm. The gap between the wall and the sheet should be larger, 15-18 mm. Those. we leave expansion gaps that allow the material to change in size under the influence of temperature and humidity. Without this necessary gap, the floor is not guaranteed to avoid squeaking or warping.
To install and fasten plywood under the laminate, self-tapping screws are used.
Self-leveling floor or concrete screed under laminate - best option. But after pouring, the drying stage of the screed begins; its duration can be from a week to a month, depending on the size of the layer. The repair threatens to take a long time, but laying plywood under the laminate can help out, reducing the duration of the repair and money spent.
Laying on a wooden floor - a lot here is determined by the strength and condition of this floor. The old board covering must first be carefully checked to see how durable it is. Next, it is prepared for working with it. The flooring must be opened to check the condition of the joists and boards. If rotten boards or joists are found, they must be replaced followed by treatment with an antiseptic.
We recommend sanding old painted boards so that there are no bulges on their surface. Before laying plywood on a wooden floor under laminate, it must be cut and adjusted. To do this, distribute the sheets on the floor, trying to cover the entire area.
Don't forget to leave gaps at each wall and between the plywood pieces. Having selected the location of each fragment, you should number them and draw a plan for their location. Next, remove the plywood. It is necessary to thoroughly clean the wooden floor from any contamination. We fasten the plywood to the wooden base with self-tapping screws, recessing their heads. We constantly monitor the evenness of the flooring, for example, using long, even slats. If we see gaps under the lath in some places, then we level these areas by placing suitable material under sheets of plywood, for example, pieces of fiberboard.
It's more difficult, but more quality way leveling the floor with plywood under the laminate. With its help, it is possible to achieve the most leveled floor from plywood flaps, on which it is easy to install any floor covering, including laminate.
We consider it useful to remind once again that plywood, when laid on joists, must have a thickness of at least 18-20 mm.
Pieces of plywood and joists need to be processed antiseptic. This will prevent mold or mildew from occurring. The floor must be dry and free of dust and dirt.
You need to draw a line on the wall, which will be a beacon, a boundary when installing the floor. The boundary must be drawn along all the walls of the room; it is accurately measured using a level so that even the smallest error does not appear during installation.
Installation of joists under plywood
We are preparing the lags. As a rule, these are ready-made bars made of durable wood. They can be purchased at any store that sells construction supplies. Try to choose bars made of wood coniferous trees, well dried. The size of the logs is approximately 50X100 mm, their length is usually 3 m. You will also need to prepare gaskets made of wood; they are installed under the logs. The dimensions of the spacers are approximately 10x20 cm, their thickness is at least 2.5 cm.
Advice: When installing logs, they should be placed perpendicular to the light rays penetrating into the window of the room. If installation is done in the hallway, the logs are placed perpendicular to the direction of people's movement. Leave a distance of approximately 50 cm between the joists.
Do not forget to leave a gap of approximately 3 cm from the wall to the joist.
During the installation of lags, it is necessary to ensure compliance with the marked level. If the joist is lower than necessary, then raise it by placing wooden wedges under it. First you need to build wooden joists along the perimeter of the room and only then begin laying the cross beams.
To fasten the joists in a wooden base, screws are used; in a concrete base, anchor screws are used.
When the sheathing is done, we begin sheathing with plywood. Plywood boards must be cut into 4 equal parts with a jigsaw. We begin to attach the square pieces to the logs like brickwork (see recommendations above), not forgetting about the compensation gaps. The joints of the plywood sheets should be in the middle of the joists. It is good to screw the plywood to the joists using self-tapping screws with plastic dowels, spaced from each other at a distance of 50 to 100 mm.
Leveling the floor under the laminate with plywood and laying it on joists is the most the right way, when it is necessary to correct a large difference in heights between different points of the floor, 5 cm or more. Plywood flooring will be a strong and level base for any floor covering, including laminate. Eco-friendly birch plywood is completely harmless to humans.
If your apartment has already been screeded, choose for yourself - lay laminated boards directly on concrete base or lay plywood first, which will ensure the most level surface of the base and thermal and sound insulation of the floor.
Let's prepare the concrete base for laying plywood:
Let's determine whether the base has dried well enough, especially if the screed is fresh. To do this, place a small piece of plastic film on the screed and press it tightly to the floor along the edges. After 3 days, check for condensation under the film. If condensation does not form, the screed is ready for coating. Otherwise, you should wait a little, and then it is advisable to use a waterproof grade of plywood.
As in previous cases, we cut the plywood sheets into four parts. We polish the cut areas. We adjust the pieces of plywood, then be sure to clean the base from dust and debris.
If the difference in surface heights in different areas does not exceed 1 cm, you can install plywood sheets directly on the concrete floor. In this case, choose plywood sheets with a thickness of at least 18 mm. Apply adhesive mastic to the surface of the screed. Plywood fragments must be laid on the base and secured with self-tapping screws along the perimeter of the sheet and also diagonally.
For large differences in heights at different points of the screed, it will be correct to level the floor with plywood and lay it on the joists. This option was discussed earlier.
Conclusion
So, the floor is leveled under the laminate with plywood and prepared for laying the laminated covering. We choose the thickness of the sheet depending on the installation method and the condition of the wooden floor. Before laying the laminate, the plywood flooring must also be sanded, most carefully at the joints in order to avoid even small differences in levels. Be sure to clean it work surface from dust and move on to the next important stage- installation of the laminate on a well-prepared base. We wish everyone success!
Laminate has now become a very popular flooring option. One of the advantages of the material is the ability to lay it on almost any base after carrying out the necessary preparatory work. For owners wooden houses or in cases where it is extremely difficult to dismantle the old plank flooring, it is possible to lay the laminate on wooden base.
Lay laminate flooring on a wooden floor quite simple, Just remember that you need a level base for installation. The height difference should not exceed 2 mm. In this regard, often, gender needs to be leveled.
One of the simple and low-cost ways to adjust a wooden floor to the desired level is to level it with sheets of plywood. This option is great will hide all the imperfections and foundation defects.
Choosing plywood for laying under laminate
It is recommended to buy plywood for laminate flooring no thinner than 10 mm. The thickness of the plywood sheet should ideally be greater than the thickness of the finished floor covering. You should also decide on the brand wooden material- it depends on the degree of moisture resistance.
FK and FSF grades of plywood are intended for work in residential premises. FSF sheets are produced using phenol-formaldehyde glue. They have good moisture resistance, but their use indoors is not advisable, as it is harmful to health. It is better to give preference to less moisture-resistant, but at the same time environmentally friendly and cheaper FC brand.
To level the base of the floor, ¾ and 2/3 grade plywood is suitable. The sheet must be sanded on at least one side. Plywood is laid sanded side up and laminate is laid on it.
Pros and cons of leveling the floor with plywood
Smoothing out differences in height of a wooden floor by laying plywood is quite universal method repairing the base before laying the floor covering. After all, this method has a number of advantages:
- the strength and moisture resistance of plywood increase the service life of the laminate;
- sound and thermal insulation properties material;
- resulting in high-quality, smooth and stable foundation;
- low price material and minimum costs for its installation;
- ease of installation allows you to quickly carry out work on leveling the floor.
There is, of course, one significant drawback to using of this material. When leveling with plywood the height of the flooring increases, which may be unacceptable for certain premises.
Methods for laying plywood on a wooden floor
There are two main ways to install plywood coverings on a wooden floor:
- mounting on logs;
laying on a wooden base.
Installation of plywood sheets using logs is the most labor-intensive way. For lag it is recommended to take boards with a thickness of 40 mm and a width 80−100 mm. When installing, maintain a distance between the axes of no more than 50 cm. The logs are placed in such a way that they top points were in the same horizontal plane.
Sheets of plywood covering are laid like brickwork, i.e. there should not be intersection of 4 seams In one place. This is done to prevent deformation.
When laying plywood, the edges of the sheets are located on the joists and fixed with self-tapping screws with intervals of no more than 30 cm. In this case, there should be a distance between the sheets - seams of about 2 mm.
Properly installed plywood covering the base of the logs will be resistant to moisture and heat. This method is great hides large differences floor height. However, it should be noted that it is not suitable for rooms with low ceilings, since the floor rises by 8-10 cm.
If the wooden base is no different large differences plane height, then we will use the method of laying plywood with glue. To level the floor without using joists, the thickness of the plywood sheets should be from 12 mm. You should start by cleaning the base from debris and dust. We cut the plywood. Without fastening, we lay it over the entire floor and adjust the pieces to size. Pre-drill holes for screws.
Then the sheets can be removed and the base prepared - saturate the surface primer. When laying, each sheet is coated with a special glue for plywood with a layer of up to 3 mm and fastened with screws. The seams between the sheets should be 2−3 mm.
In this manner smooth and durable base under finishing The floor is quickly installed and does not require large expenditures.
Cutting and fitting plywood
Plywood is cut according to the floor area. It is necessary to take into account that when laying away from the wall it is done indentation 10 mm and the gap between the seams is 2-3 mm. Cutting sheets into squares the right size, you need to check their edges for delamination at the ends and the presence other defects. If the edge is damaged, the workpiece should be replaced.
Plywood is laid in a checkerboard pattern. The sheets are drilled to the base with self-tapping screws along the perimeter and additionally along the surface in increments of about 20 cm. For quick and convenient installation It is recommended to number the sheets and also mark the fastening points with self-tapping screws.
After fitting, the blanks are removed, the base is cleaned from dirt and dust. Before laying, the prepared sheets should be impregnated with an antiseptic in order to increase their service life. Then you can begin installation.
Plywood laying technology
- The plywood is fastened to the wooden floor according to a pre-planned layout of the sheets. Self-tapping screws or screws with plastic dowels are used for fastening. Holes for self-tapping screws are pre-drilled and countersunk with a large-diameter drill in order to “hide” the screw head.
- The mounted plywood base for laying the laminate is sanded and then coated with protective compounds that increase moisture resistance and wear resistance.
- A special laminate underlay is laid on top, which has noise-absorbing and heat-insulating properties.
The technology of leveling the floor with plywood allows prepare for installation finishing coating wooden base of any quality. If the installation of rough plywood flooring is carried out in accordance with necessary requirements, then the laminate will last for a long time. Environmental Safety, The unpretentiousness and strength of the material make it possible to use it in residential premises to create a smooth and stable floor.
Old wood covering, whether it is parquet or an ordinary board, is not always easy or advisable to dismantle. Especially when it comes to preparing for hard products such as laminate. In most cases, it is enough to lay plywood on top of a wooden floor yourself to get an even and solid foundation.
According to the instructions, laying laminate flooring is allowed if the difference in height of the main floor is no more than 2 mm. To achieve this material ideal better than plywood cannot be found, but it must meet strict requirements:
1. Surface quality - for the substrate a cheap 3/4 grade will be enough, buy more expensive brands doesn't make sense. The main thing that front side was sanded smooth, since it is on it that the laminate will lie. Otherwise, laying the plywood will be completed by subsequent sanding.
2. Thickness – from 12 mm, but experts recommend laying panels that are thicker than the laminate itself so that they do not sag under the weight of the finished floor. There is no need to take very powerful slabs as a safety net, since you will have to pay for every millimeter, and high strength will be unclaimed.
3. The moisture resistance of the panels must correspond to the conditions in the room. For residential rooms will do FC, in conditions high humidity it is better to take FSF or its laminated version FOF, but both brands differ in the toxicity of the resins they contain and will require additional processing edges after cutting.
Plywood can be attached directly to a wooden floor using glue and screws if the difference in height of the base does not exceed 5 mm. If the difference is from 1 to 8 cm, you will need to install a sheathing or install a system of adjustable joists.
Preparation of sheets
To increase the service life of the coating, it is worth treating both the old wooden floor and the plywood itself with antiseptic compounds, and then give them time to dry.
Before installation, pressed panels must be cut in accordance with the shape and area of the room. In this case, narrow strips should be left free near the walls - an expansion joint 10-20 mm wide. There is nothing wrong with this - the gaps around the perimeter will subsequently be closed with a plinth.
Laying plywood under laminate will become easier if you deal not with full-size slabs (1.25x1.25 m), but with small squares, for which they are cut into 4 parts. They are easier to install in any room, cut at various protrusions on the wall, and the number of damping joints between them provides sufficient compensation for thermal deformations. Installation large sheets This is also acceptable, and it can even be done faster, but it is still difficult to implement alone.
After trimming, you need to carefully inspect the resulting edges and replace the sheets on which the veneer is peeling or the edges are frayed. To reduce the number of defective squares, it is better to cut the panels according to the markings with a jigsaw.
Installation instructions
Plywood under the laminate on a wooden floor is simply glued if the old coating initially has non-critical differences in surface height.
The procedure for performing installation work:
1. Cut the sheets according to the shape of the room and adjust them to size, number the elements and sketch the resulting installation diagram on paper.
2. Drill holes through the laid slabs to the old wooden floor for screws. According to the technology, finished holes need to be countersunk with a thicker drill, so that later you can recess the heads of the screws without damaging the top layer of veneer.
3. Raise the drilled sheets and treat the old coating with a wood primer. As a primer, you can use the same glue that is used to attach plywood, but diluted with a suitable solvent to a liquid state.
4. Clear the boards of debris, repair or replace creaking slats if necessary, and vacuum the room.
5. Apply with a notched trowel to reverse side plywood or glue no more than 3 mm thick directly onto the wooden floor and lay the slabs in place.
6. Additionally secure with self-tapping screws along the perimeter and diagonally in increments of 150-200 mm. The attachment points should be located no closer than 20 mm from the edge of the plywood square. This technology will prevent swelling and securely fix.
7. Sand and coat protective composition, for example, varnish, floor surface.
Installation with glue is carried out quite quickly, it is easy to do it yourself, and you do not need to spend a lot of money. With this method, plywood is laid under the laminate leaving small gaps - about 2-3 mm. The laying pattern is in a checkerboard pattern with offset sheets so that the middle of each panel has a seam in the adjacent row (as in brickwork).
Quality control
How correctly all the work was done can be checked in the following ways:
1. Lightly tap the sheets and listen to the sound they make. If the plywood is poorly glued to the wooden floor, the voids will respond with a dull sound. Such slabs will have to be torn off and laid again.
2. Lay a long, flat strip on the plywood surface. The gaps between the sheathing and the rail should be less than 2 mm. Blemishes can be eliminated by grinding or tightening/loosening the screws.
3. It is easy to determine the horizontalness of the floor covering - using carpenter level. For laminated boards, a slope of no more than 0.2% is allowed.
Laying laminate flooring on plywood - quite simple task, if the surface of the main floor is well leveled and covered with a shock-absorbing underlay. You can start from any corner, collecting long rows of slats. Each resulting line of laminate is joined to the previous one using side locks.
Leveling price
The cost of floor preparation may not be less costs for the purchase of laminate. Here a lot depends on the prices of the materials that will be used and their quantities. Required:
- Plywood - in terms of the area of the room.
- Polypropylene backing and tape.
- Hardware.
- Adhesive and primer composition for wood.
If you do not do the leveling of the floor under the laminate yourself, but invite a specialist, the price for the work of the master will be added to the costs. Estimated cost of basic operations for square meter the surface today is approximately this:
- Sanding the old coating – 119-160 rubles.
- Laying plywood – 200.
- Sanding – 160.
- Varnishing – 100.
- Laying laminate – from 320 rubles and above, depending on the chosen scheme.
