Mating drywall to plaster on an inside corner

acme54321

Hey Guys,

Quick question/advice request:

I am installing some drywall that is butting up to old plaster in a corner. The plaster the drywall is replacing was about 1" thick, using 1/2" drywall.

My plan is to scrape the area were the old plaster met up, then mount the drywall butted up to the plaster like shown, then use some hot mud to smooth out the 1/2" strip still exposed where the old plaster was and fill in any areas where there are gaps (drywall is a little jagged). Then just tape up the corner like normal.

Sound good or should I do it some other way. Never done drywall to plaster in a corner like this.

Thanks in advance.

We don't get to see much real plaster here in Phoenix, but ... I would do it just like you are.

While a larger waste of material, would it not be easier to double the drywall up to the 1" thickness, or at least shim the wall 1/2" behind the drywall?

Food for thought.

I thought about that, but I think it would be just as easy to use some mud to fill any voids and smooth out the edge. I am going to tape over that area anyway so it doesn't have to look good or anything.

Gonna be tricky to smooth out but doable.
