How do you intersect drywall (or in my case plaster) into tile on the same plane?
 

Since fishtale's issue was solved and I have a similar question I'll ask it here. How do you intersect drywall (or in my case plaster) into tile on the same plane?

Here is my situation: I am going to be removing the tile and plaster/cement from the shower area of my bathroom and replacing it with 1/2" cement board and new tile. On this same wall there is existing plaster that I want to keep, but it's about 3/4" thick. It is gypsum lath and plaster, in some areas it might even be a little thicker.

So how would I meet the new tile to the existing plaster? I need to do this on both sides of the shower.

Probably shouldn't hijack someone elses thread when it is so easy to start your own.:) The subject matter is entirely different.:)

As I mentioned, the thread starter's mission was accomplished so I figured this would be the perfect place to continue the discussion of meeting tile to drywall, etc.

Sorry :rolleyes:

Thats ok. I'll try to answer it.
I'd cut the plaster very carefully so that it's a couple of inches behind the tiled part. Sometimes the plaster is 1/2" thick on top of the gypsum lath.

Its better to start your own thread. Even when topics are similar. Since the OP may not want to be notified every time a response is made. And it not be in response to him.

Altering plastered walls is almost always a dubious task. Since the plaster is added to either wood lath, wire lath, or plaster sub-boards, by hand the application can vary seriously in thickness.

I have done this a couple of different ways. One way is to build out the wall using 1/2" and 1/4" drywall then waterproofing it in a shower.

The other way is to still do a build-out with sheet goods but leave it short then fill it with thinset or plaster and waterproof that.

Either way it can be tricky to get it just right.

Sometimes a nice neat cut into the old plaster and adding a chair rail trim tile at that cut will disguise any variations.:)
