i'm moving towards tiling the floor and walls of my shower. i'll also tile the bathroom floor. i bought the premixed thinset at HD hoping to use it for everything. i think it was the only option. maybe not. :/
so i read the label last night and it says "not for use in shower floors or other consistently wet areas" and "not for bonding cement backerboard to subfloors". is there something else i should be using for those?
Very much not an expert here, but I've been doing a lot of research on this topic as I am planning on re-doing my shower.
To answer your question, No, the premixed stuff is a no-no.
I won't give any advice past that since I'm basically a novice too, although I would mention questions about tiling showers are very common here. If you go to the flooring forum here at the top of the page you will find a sub-forum on tiling. Dig around there and you will find a lot of useful info. Or spend some time and use this sites' search engine. It may give you answers to questions you didn't know you had!
thanks, blondsense. i was at HD looking at the 6 or 7 different kinds of thinset. some specifically said not to use for the shower floor. some made no mention. i called the tech support number for Custom Building Products on the back of the package and had someone on the line in 30 seconds. they recommended the versabond.
