When it is required to level the surface of the floor, for example, under laying a laminate or parquet, sheets of plywood can come to the rescue. In a short time you can get a flat and strong surface.
Plywood has sufficient properties for such a task
– high strength and stress resistance
– ease and speed of installation, even in large areas
– Unpretentity in operation
– There are moisture -resistant plywood varieties

Which plywood to choose depends on the room
– Plywood FBA is suitable in the bedroom and the children’s room, it uses natural albuminocasein glue. The advantage of such plywood is environmental friendliness, the disadvantage is not moisture resistance.
– The most durable plywood with the marking of the FSF. However, it uses formaldehyde glue harmful to humans
– Something medium plywood marked FC, less harmful and not as afraid of water as a plywood of the FBA
Tools and materials should be prepared in advance
– drill
– Scarring
– Self-tapping screws 80mm long to remove floor creaking, and 35-50 mm for plywood itself
– Lobzik or hacksaw
– level
– Roulette, pencil
Preparation of the floor
First you should eliminate the creak and staggering of the boards. With the help of long self -tapping screws, fasten each board to the lag. The location of the lag can be determined by the old driven nails, or by taking out one of the boards, for example at the wall.
What to do if the floor is not very even. Small deviations are aligned with a substrate, the difference more than 10mm will require laying the lag exhibited using the level.
Laying plywood sheets directly on the floor
Using measurements, we determine the location of the plywood and carry out the cutting. Lay the sheets with a displacement, that is, prevent the joint from all four angles. It should not be forgotten that the material from temperature and moisture drops can expand, therefore, the gaps between the sheets and near the walls are required 3-5 mm. Screw the plywood from the angle from the door. The sheet is screwed from the center, and then along the edges so that the bubbles do not form. At a distance of about 20-30 cm. Hats are good to sink into the sheet, in order to avoid hillocks.
Laying plywood on the lags
Lags make plywood about 4 cm wide. In the emerging gaps between the floor and the lags, pieces of plywood of suitable thickness are placed. Lags are either glued with glue on wood, or fixed to self -tapping screws. Plywood is also attached to the lags for self -tapping screws.
Plywood coating with a neat approach will turn out to be even and durable, you can safely lay any coating – linoleum, parquet, laminate, carpet.
