Wondering if anyone can give me a list of alternatives to Ditra and their strengths/weaknesses for use with tile kitchen countertops. Sounds like Ditra is top of the line, but it's not available in my area (easily available, at least.)
I've seen one site that recommends 15 pound roofing felt, reinforced asphalt paper, or 4 mil. Polyethylene-sheeting for a moisture-barrier on kitchen countertop. Does that make sense?
