Used this to lay new tiles over existing ones around our fireplace. We used 6×6″ tiles that were about 1 pound each. It was pretty easy to reposition the tiles when we needed to, until that point you pressed them down. then it is fairly difficult to budge them (but that is the point of the matting, to hold them in place) It worked very well for our application but I can see how it might be difficult to get this matting set in place when its not a long, straight and equal size surface.
