Engineered Timber Wear Layer and Board Thickness Explained

The wear layer is the visible timber above the engineered core. Its thickness can influence the scope for future sanding, but the number of possible refinishes cannot be determined from one number alone.

Surface texture, factory finish, bevels, product condition and the sanding process also affect what may be practical later.

A board should be assessed as a complete system: wear layer, total thickness, core construction, dimensions, profile, finish and manufacturing tolerances. A thicker specification is not automatically the better fit for every project.

The construction needs to suit the substrate, installation method, room conditions and adjoining finishes.

For renovations, finished floor height can affect doors, stairs, tiles and cabinetry. For wide-plank floors, substrate tolerance, board stability and setout become especially important.
