I have an old house with a real issue in a couple of the rooms. The rooms have plaster and lathe walls and ceilings and the plaster itself is in good condition. There appears to be a couple of layers of paint on the plaster, and then painted knock-down texture on top of that. The problem is the original paint is losing adhesion with the plaster and as a result all the layers are peeling off. I can put a putty knife at the edge of a small crack and effortlessly peel off sheets of paint and texture right down to the plaster. This is only an issue on some sections of the wall - on other sections everything is well attached. So, after exploring this situation for a couple of days and removing pretty much all that was loose, my walls are about 1/3 stripped to the plaster - much too far gone to go back, but still impossibly far from the nice uniform bare plaster finish. My idea at this point is to skim a few coats of drywall mud over everything and achieve uniformity by filling in and then over the knock-down texture, but I have been reading that pre-mixed joint compound does not adhere well to plaster. So I am a bit lost as to what to do next. I have worked a lot with plain drywall but am new to plaster and texture. Any advice or insight from anyone with experience would be greatly appreciated. Thanks for reading.
