For in-expensive(cheap), :) I used an epoxy garage floor paint from Lowes thats tintable, made mine a very pale off-white and added the sand aggregate to the paint, 2 coats on my 19-6 and still have about 1/3 of a gallon left...it's not too rough on the feet for barefooting, but you don't slide either
since I had a new floor and no factory mold for the nice pattern I just used this. May have spent $55 including a throw away brush and roller.
