Is this used like a thick layer, acrylic or such, over tile, concrete, wood, etc., like those tables and counters you see in restaurants and bars and even floors? I've seen some close to 1/4" thick, or more, that makes a solid adhered surface and looks more or less like a glass top on a surface except bonded and impregnating into the surface it is on, somewhat. I can see that helping if it could hold up and stay bonded under swimming pool conditions. Heck, I've used plenty of satin polyurethane over wall paper in damp areas but another question arises.... wouldn't the layer to be protected need some kind of roughing for the "resin" to adhere properly? BTW... I've seen some old pools and fountains, some virtually or approaching, being antiques, that still have their original tiles. Has the quality of products deteriorated over the "eons"? I do know that when I and a crew were trying to break up some concrete steps, poured during the depression era, using heavy sledge hammers, we couldn't do it. One guy was 6'7" and very strong; the rest pretty hardy guys. I had to go to headquarters to get jack hammers. (To be honest, foreman let me slack off on this one. I was the only, and first woman on the crew, back in early 70's, working for the Parks and Recreation Dept of city, while attending university. Great and fun job; learned a lot and got to operate a lot of equipment that I never would have gotten close to otherwise.) :blah: :blah:
