Leveling the floor with plywood do it yourself

The floor is an important element of any housing, determining the aesthetically neat look of the rooms and the level of thermal comfort in them. For the floor in your house to be durable, smooth and beautiful, just purchasing decorative flooring will not be enough. Unfortunately, the floor surface is often far from ideal. This is an unpleasant moment, but reparable. You can always try to do leveling the floor with plywood with your own hands - this is the most accessible and easy way, using which you can prepare the foundation of the floor for laying the floor you like. If, by virtue of employment, you have absolutely no time for repairs, then contact one of the construction companies with a proven reputation, and experts will help eliminate the defects of the surface of your floor.

Recommendations

1. To level the floor, use birch plywood, which, unlike chipboard and fiberboard, is an environmentally friendly, natural material that will positively affect the health of residents.
2. The optimum thickness of sheets used for leveling the floor surface is 10-12mm. Then the floor will definitely be strong and even.
3. For leveling the floors, it is not necessary to take the best quality plywood, sheets of the latest class are suitable.

Plywood must be moisture resistant.

Plywood leveling

• Before installing plywood sheets, be sure to examine the subfloor for defects. Make sure that the base of the floor (concrete screed) is made with high quality, in compliance with all the requirements for technology. If the draft floor is wooden, then you should check the presence of loosened boards in it, which must be firmly fixed with screws. The cracked boards should be replaced as a whole, so that later the floors do not creak under their feet.
• In the case of a concrete screed, do not forget to check the moisture level of the subfloor, which you are preparing for plywood flooring, with cellophane. It is important that the substrate is dry, otherwise excessive moisture on the subfloor may cause the floor to become unusable.
• A sturdy waterproofing backing should be laid on top of the concrete screed.
• Clean dirt and dust thoroughly before starting work.

• In addition to leveling the floor on a concrete screed, a common method of leveling the floor with plywood sheets on logs. In this case, a frame made of wooden bars using a special technology is installed on the concrete base of the floor.
• When you are sure that the concrete base is well-dried, and the wooden frame you have made is firmly fixed, you can begin the process of cutting plywood. Plywood is sold in fairly large sheets of 1.5 x 1.5 m. Sheets of large sizes laid on the floor is not always advisable. As a rule, plywood is divided into small squares, because a smaller square is not as susceptible to deformation as a large square. Usually the sheet is cut into four squares, which are laid out step by step (without fixing) on ​​the prepared floor to determine the quantity of material used.
• Between the sheets should be sure to keep small gaps. The optimal width of the damper seams - from 8 to 10mm. Plywood sheets should not be allowed to fit tightly against the walls of the room. The distance between the wall and the extreme squares should be at least one and a half centimeters - only this way the floor can “breathe” and will be protected from the deformation of the floors.

• Fix the fitted plywood sheets in a staggered manner (in the style of “brickwork”) and number them in order not to confuse them with the final installation. Do not forget to draw up the layout of the cut pieces (by numbers) and only after that temporarily remove the cut plywood from the floor.
• Parquet flooring specialists advise to pre-coat the base of the floor with a primer-primer or special mastic to ensure its greater durability and strength. Adhesive mastic is applied with a construction toothed spatula. The thickness of the primer layer is usually about two millimeters.
• After processing the cut sheets with a primer, you can proceed to their laying: fix each sheet of plywood in its allotted place and screw it around the perimeter with self-tapping screws. Try to keep a distance of 15-20cm between the screws to secure the sheets.
• Visually inspect the resulting floor and check its evenness with a two-meter rail-rule: attach the rail-rule to the surface of the plywood in different places, alternately orienting it in different directions. If everything is in order, polish and clean the finished surface from dust.

Now your plywood floor has become the ideal smooth base for the further installation of any coating you choose: laminate, parquet, carpet or linoleum. Before laying laminate, spread the substrate - heat and sound insulation layer that will perform cushioning functions.

As you can see, if you have time, small skills for the repair and the corresponding tool, you can do the floor leveling with your own plywood.
