Plywood is produced in various thicknesses, grinding properties, and processing. That`s why a builder always faces an issue: which subfloor plywood to choose to lay on the floor for it to be robust ground for the decorative covering. Although plywood floor likely stands as a rough cut, necessary for the further laying of the finishing coating. But, nice texture of the wood inspires many to make the finishing coating from the plywood – varnishing it after. Thicker plywood layer guarantees less bending and shaking of the floor what means lifetime of the floor and of everything on it directly depends on the plywood layer.
Grade: using plywood for the finishing coating can require high-quality plywood of A or B grade, to use plywood as a subfloor for the parquet – it is reasonable to apply simpler grades as C and D.
