bathtub/shower enclosure waterproofing for tiling
Posted: Sat Apr 27, 2019 12:54 pm
I'm in the process of a bathroom reno. My question is related to the issue of vapor barrier on exterior walls and how it affects a waterproofing system such as redgard. I'm reading alot of information saying its not acceptable as it will create a moisture release problem in the system.here was my initial plan: 6mil poly attached to framing, cbu, then redgard.What I was wondering:If the wall sections below the tub are left unfinished,ie,no wall sheeting(typical) would this allow an escape route for any moisture that my get past the tile, grout,etc, and find itself between the cbu and redgard?I hope my question is not confusing?
