# Nail-down

**Fastening flooring mechanically to a wood subfloor — correct for solid hardwood over plywood.**

Nail-down is the method for solid hardwood over plywood joists. It requires a substrate that accepts fasteners, which is why it has no application over concrete.

Method is determined by substrate and product construction, in that order. It is not a preference and not a sales option.
