Ardex Feather Finish can be used for filling in gaps, gouges, ridges and depressions to help smooth out virtually any type of subfloor that you need to work on.
Application is simple; one full 10lb bag should be mixed with 2.5 quarts of water and you're ready to go. Remember that it has a 15-20 minute pot life, so only mix prior to use. If you don't need a whole bag for a job, then mix 2 parts powder to 1 part water.
One bag can roughly cover up to 16.7sq ft at 1/4" or up to 33.3sq ft at 1/8".
