Reply to comment by M365Certified in How to fix hole in plaster? by elysiansaurus

You seem knowledgeable - I'm going to hijack and ask a question. I have a section of plaster that was adhered directly to brick. A less-than-knowledgeable about old houses contractor (and I won't hire again) cut a section out, about 8"x8" square. Now I need to fix it. I don't even know how I would go about putting drywall on that. Any suggestions?

You get a gypsum based adhesive for putting the drywall directly on surfaces. Call dot and dab attaching. Just cut out a square of drywall, throw a handfull of adhesive on the wall and stick in the square.

​

For a pro tip, cut the patch a few inches oversize, and cut off the plaster on the excess leaving the paper attached. put a layer of jointing compound under where the paper overlaps the old drywall and it'll be much easier to feather out and blend later

a section that small is also possible to just fill in with new gypsum in one or two coats and level it off to be quite flat with the existing wall. i guess drywalling is a more useful skill to develop in general however, depending on region and materials availability
