What should be put on shower walls before tile?
We had the old tile knocked out and new plumbing done.
Normal non waterproof (im assuming) fiberglass insulation was put back and then durock (also seemingly non waterproof) dry wall was out up.
Shouldnt thry hsve used waterproof drywall? Is the old insulation ok?
What are all these ither materials I here about for shower walls? Kerdi etc.?
Jve seen talk sbout Vapor barriers and waterproofing and Im afraid mine wasnt done right and need to fimd out now before tile goes on.
