On the concrete floors of the tie and wash stalls? I can't find any information on anyone using it for this purpose. They claim the product can be used on concrete although its most popular use is truck beds, I've found where some have used it on horse trailers but not finding much on its use in a tie stall or similar situation. My thoughts are that it would make a nice even non slick surface that would be easy to clean.
