I also heard recommendations about this product and thought I'd try it. After it dried, about 5 days, we placed non-slip throw rugs down on the high traffic areas. After a few months I noticed that the varnish picked up the pattern of the rug's rubberized backing and that a dark film was sticking to the floor. I decided to remove the varnish and had a heck of a time. The rubber from the mats imbedded into the varnish creating a wax paste that was very hard to remove. Did I do something wrong?
