With Ardex Feather Finish, you can be sure that your subfloor is ready for your new floor coverings. ARDEX Feather Finish can be used for flash-patching, skim-coating and filling ridges, gouges, depressions and seams on virtually any type of subfloor. Ardex Feather Finish provides a smooth, permanent finish to a variety of substrates prior to the hardwood flooring installation.
