There are four grades of plywood, of which only two are suitable for floor installation. When choosing a material, you need to focus on its brand, thickness, quality of veneer wood, grade, grinding method and emission class.
In apartments and private houses, significant differences in elevation in terms of sex are not uncommon. Since it is unreasonable to lay the flooring on such a base, the curved surface must be leveled. Removing floorboards is a time-consuming and lengthy process, so you can focus on installing a self-leveling screed, on top of which plywood sheets are laid.
What is plywood?
Plywood - a sheet material, which is a structure of thin veneer sheets, between which there is an adhesive layer. The strength of the product determines the number of sheets of wood. The veneer is laid in such a way that the direction of the fiber of the sheets is mutually perpendicular. Plywood is made by gluing under pressure. After drying, it is processed with protective compounds.
