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.

- SubfloorWhat the finished floor is installed onto — plywood over joists, a concrete slab, or a radiant assembly — and the thing that determines the installation method.
- Glue-downBonding flooring directly to the substrate with adhesive — correct for engineered flooring over concrete, and in condominiums.
- FloatingInstalling flooring so it rests on the substrate without being fastened or bonded to it — correct over radiant heat, or where acoustic separation is required.
