Since you're just applying a band-aide, you can get away with just slipping some more wood to fasten too and hope. After the new board is screwed in, glue the edges so it'll bond to the old wallboard. Let dry overnight, then bond the tiles. Let dry, then caulk the perimeter, cuz it'll likely crack with grout, and either caulk the rest or grout the rest.

I would look further for the right size tiles, 1/4" joints with bright glazed wall tiles would look hideous even if they were all that way. Your choice, it's not gonna last anyway.

list of materials;

the board, screws, thinset mortar - comes in #50 bags, YIKES, or 1 qt. of mastic, or just use adhesive/caulk, caulk, grout, (sanded if wider than 1/8"), Sealer is for the grout but has nothing to do with waterproofing it. Sealer does NOT make it waterproof. Use sealer as a maintenance item to make grout easier to clean. If you're really just looking for a temp fix, this should do it.


Thanks Jaz, I can see you are really good at this stuff!
I really like the tip of caulking around the perimeter, I never would have thought of that. I would remove more tiles but every tile I remove takes the wallboard with it and in pieces.
But what do you mean by glue the edges so it'll bond to the old wallboard?
Do I just use mastic?

Thanks, that's because I've been doing this too lon....ah..ah...ah, I mean a long time!

Use a 4" tapered putty knife and tap tap with a hammer slicing the tiles off. Should be minimal damage unless the board is weak.

By gluing the edges, I meant the edges of the new and old board, glue them together. But if you remove more tiles you will be able to apply fiberglass mesh tape and thinset to create a monolithic base. That's the best way. Do not use drywall compound or anything made with gypsum. Use the thinset or mastic if you were going that way.
