Tiling over old tile

Is it possible to install new ceramic tile over old ceramic tile? If so, what are the procedures to follow before installing. That is, what needs to be done to old tile so it will adhere correctly?

A bonding primer is required over top of the old tile. The old tile must also be sound, no cracks or tenting or hollow sounding areas.. we would use 254 platinum for Max bond

I have used liquid membranes for my walk-in showers, both walls and floor and have not had any problems, including the first one that I did 13 years ago. I am currently putting in a curb walk-in shower in the ranch style, slab on grade house that I am building. I have used the concrete grinder to create the drain slope in the actual concrete slab, and the walls are concrete board seamed with thinset mortar. The Flofx drain is set with thinset so all is ready for applying the liquid membrane. I’m not opposed to using a sheet membrane but my question is, what would be the reasons I would go with a sheet membrane instead of liquid membrane for the floor being that there is no worries of any moisture still being in the concrete?

Flofx drain with goboard pre-sloped panels

Anyone know if it’s possible to use the Flofx drain with goboard presloped panels? And the best way to tackle this? We poured self leveler in the bathroom as the subfloor is old 2” thick t&g. I’m concerned about the goboard point drain not holding up over time and was considering the Flofx drain in stead but not sure how that would work.

I use go board daily. On the walls. I've seen that pre-sloped pan kit, and it scares me with all the seams.

The point you are at, I would probably prefer to just use a kerdi pan or similar for the floor. That will accept the flofx no problem.

Dry pack is my preferred since I do it a lot, but I think in your case, an easy single unit foam pan will be better.

There always tile redi pans. This take care of everything in one shot.

Sufficient Bracing for Shower Door?

Hey all! We are at the point of almost being ready to measure for glass for a frameless pivot door and knee wall glass. I have a concern that has just come to mind regarding the bracing for the side where the hinges will be mounted. This is a renovation so where the wall for this shower ended up landing in the existing wall didnt have a stud. Instead, they added a 2x4 turned sideways and scabbed it in by attaching it to the existing sill and then attaching it to the back of the existing sheetrock at the top and placed hardie over it. The preexisting vent pipe was kept but adding the new T piece and furnco to it made it too thick to be concealed within the backer boards Im assuming, so they simply placed mesh tape over it and added a dab of waterproofing. The wall…
