What plywood to level the wooden floor in a city apartment?
I turn to experts for advice, for this reason: I want to understand the classification of plywood. I make repairs in the apartment, where since the “Soviet” times the floor was made of boards. In principle, everything is fine, but not perfect, of course. I plan to put good linoleum on the floor, but before that I know that it is necessary to level the surface of the floor. That's what I want to use plywood for. Here difficulties appeared for me, it turns out that there are several categories and each has its own purpose.
Yes, the truly modern building materials market offers plywood of various types and grades. Among the key differences are worth noting:
- Appearance.
- Life time.
- Destination
- Cost.
Plywood classification
Though by and large, with proper analysis, sorting out the types of plywood is not that difficult. In total there are 4 brands of this building material:
- FC
- FSF
- Fb
- Fof
Note! Plywood brand FB and FOF is positioned by manufacturers as a material for industrial use.
In your case, to level the floor you need to use plywood of the FC or FSF brand. These two materials are almost identical in their technical indicators, with the exception of one single parameter - moisture resistance.
Specific Usage Recommendations
If nevertheless you do not know which brand of these two to give preference, then we recommend FC plywood. And this despite the fact that it is FSF that is most able to resist the effects of moisture. The fact is that the material of this brand is not the best option when installing the floor, since it is produced using highly toxic compounds, including formaldehydes.
Important! According to SNiP, plywood of the FSF brand has no restrictions on use in residential premises. However, it must be operated under certain conditions. If humidity or temperature changes, the plywood will begin to emit harmful components.
FC plywood has an average moisture resistance, but its production technology involves the use of less toxic substances. For gluing veneer layers use safe glue with urea resins.
