The most common wood flooring installation methods are:
Nail down – Nailing down wood floors is the most common installation method. The process involves nailing or stapling the wood flooring material directly to a wood subfloor. This istallation method works for both Solid and Engineered wood flooring, but only on wood subfloors.
Glue down – The glue down installation method involves using adhesive to adhere the flooring material directly to the subfloor, or to a wood subfloor ( for a moisture barrier installed and sound insulation) This installation method it is mostly common for Solid wood flooring.
Floating – Using this installation method, the flooring material is neither nailed nor glued to the subfloor or wood subfloor, but floated above. The wood flooring, usually Engineered wood floor is either glued or clipped to itself, both tongue to groove, and at end joints. This gives the floor stability without actually fastening it to the subfloor material beneath it.
