Giải thích
Panels used as subfloor-underlayment for thin resilient flooring must be specifically rated for that use and have a smooth (touch-sanded) face so joints and grain do not telegraph. Knot size, veneer color, and sheer weight are not the controlling factors for a finish-ready underlayment surface.
