This may be a bit of a stupid question, but I am wondering how thin I can apply mud to a cement wall to even out any holes? Is mud even the best material to use over concrete?
Please don't let the fact that this is a jacuzzi wall deter you from giving me an answer that applies to a shower wall
Basically, I chipped away old plaster and some rust stains that I will patch with concrete. However, the walls, seats, and floor are heavily pock-marked from the chipping and I want to add a layer of mud to even and straighten them out. On two of the walls, I will have my 1" glass tiles butt up against my waterline tile, which is a little thicker. I want to make up the difference in thickness with mud as well, but not have the glass tile sit higher in the end due to the mud bed. Since these two walls are contiguous with the pool wall, I also cannot raise the waterline tile mud bed much, if at all.
