Joining Drywall/Plaster

Does anyone have experience joining new drywall to existing plaster? I have a hole from an old built-in medicine cabinet I need to close and Iím not sure if the traditional tape and mud method between the two materials will work... I've read a number of conflicting things online on otehr sites...
Thx

Re: Joining Drywall/Plaster

Use plaster not joint compound. The hardest part is making sure you dont damage the plaster lath when you are going out to the studs. You will need to cut back the the plaster and the wooden slats so that you can put in a piece of drywall. I have never used joint compound with plaster but I know that plaster will spread like joint compound. When we ran new wireing in my friends house it was a nitemare as the plaster kept cracking as we tried cutting back the wall. We ended up going wall to wall with 2 sheets of dry wall as the time/frustration saved was worth the $10 of drywall. good luck

Re: Joining Drywall/Plaster

can be done. use some 1" boards to make a lip to attach the drywall to. make the hole square. use mesh tape, not paper. use a wide knife to blend out a good distance. use several light coats and sand in between.

Vert/blackfusion,

Thanks for the feedback. Have either of you used mud over the dry wall to give a slightly uneven look? The plasters not perfect so I want to make the new drywall blend into the rest of the wall. I'm thinking very thin coat over the drywall...

@John_in_the_LBC

I'm not sure I have enough room for something like that, lol... But it's impressive!

the uneven look is because plaster is put on with a trowel like spreading tile mastic. you can put a skim coat of mud over the drywall patch and try to trowel it out to get the same effect using your 6" drywall blade. Depending on how it looks you can try to sponge it to give it texture. however when you sand it it will be smooth again. Your going to have to play around with it to get the look your going for. try on a piece of extra drywall. Again the only experience I have had ended up with us banging on 1/2" sheets of drywall over the busted up plaster. took us 4+ hours to try and patch it and 20 min to hang two sheets of drywall and blend at the corners . your call.

this is the basic technique.
Skim coating a plaster wall like a pro

@blackfusion06

Thanks for the additional info and video. The guy in the video could probably take care of my patch in one pass (he's a machine)!

I'll post a few photos (before/after) once I kickoff the project this weekend...

Thanks again-
