INSTALLING SOLID HARDWOOD FLOORS

Solid wood flooring must be installed directly to concrete or sand-cement screed sub-floors by fully bonding with a purpose-made permanently flexible adhesive (e.g. 1 component Polyurethane or SMP) with an appropriate liquid DPM/primer as barriers applied to the sub-floor.

The adhesive is applied to the sub-floor only using a V-notched trowel, which creates ridges of adhesive which the flooring is bedded into when laid. Always use the trowel type which is recommended by the manufacturer of the flooring adhesive for the type of wood flooring being installed and replace worn trowels.

When installing onto a wood-based sub-floor (e.g. plywood or original floorboards) then the hardwood floor must be screwed or secret nailed ensuring that some form of moisture barrier is applied before laying of hardwood floor.

Solid wood floors that are secret nailed or screwed onto joists or battens as a load-bearing floor which is known as mechanical fixing, this method is also be used for solid-wood flooring onto an existing timber floor, or any sound sub-floor which is thick enough to adequately take a nail or screw (e.g. building grade chipboard)
