How do I repair this plaster ceiling crack / sag?
Comments (9)sfsuperstar: "My husband's really doesn't like the ridge, and the rest of the ceiling is so smooth he thinks trying to blend a 3/4" deep ridge will look obvious, so his tentative plan as of this evening is to remove the ridge of mesh to try to flatten it, then try to redo the crack repair smooth." That sounds reasonable. You may have to widen the crack just a bit more and clean it out, trying to cut under the edges as much as you can so the patching material has a place to grab in to and hang on. sfsuperstar: "It seems that the sagging part isn't an edge of the mesh, but is a center part of the mesh -- like an upside-down mini-mountain ridge. Should he try to cut out just the ridge part of the mesh with an exacto knife, or does he have to remove the whole mesh tape (even the part that's not sagging)?' I would guess it depends on how easily it cuts. I've not used it before, so I can't say. If it ravels and gets frayed and stringy, then it may be hard to cover over again with whatever you use. sfsuperstar: "And should he re-repair the crack / removal damage with flat drywall tape and joint compound? Or is there something plaster-specific that he should use? I'm not familiar with the patching plaster you mentioned." It may be OK to use the drywall tape, but I would wonder how much it would give or move under changes in temp and humidity in the ceiling without breaking loose at some point. I really don't know! We got the patching plaster at the hardware store; it's dry and comes in fairly small bags, and you just add it to a small amount of water in a container and let it absorb the water, stirring or 'folding' the mixture only very gently. If memory serves, drywall compound is still water soluble after it dries, while the patching plaster is a bit more impervious to water once it dries. Drywall compound also has a tendency to crack easily as it dries if it's applied to thickly, and the patching plaster doesn't do that as readily....See MorePlaster repair
Comments (2)What you have is two coat plaster. One of the first uses for gyspum panels was as a base for plaster, eliminating one layer (wood and metal lathe need 3 coats). Use Easysand or Durabond. Durabond is VERY hard to sand, so only use it if you can do smooth work. Some bonding compound (really just thin polyvinyl glue) would be a good idea. Mist the surface with a sprayer till just damp, apply bonding agent, wait about 5-10 minutes so the agent is tacky but not actually set, then apply the first layer of setting compound. If you know how to use a plasterer's trowel it will go faster than drywall knives. If you cannot find any bonding compound you can cut white Elmers glue with water to about the consistency of heavy cream. Eucoweld is one bonding agent....See MorePrep for plaster repair
Comments (3)Depends on whether the keys are still holding it to the lathe. If not, Big Wally's Plaster Magic can be used to re-secure it, and you can skim coat over top of it....See MoreCeiling Repair - Chipped Plaster
Comments (1)That's the type of "texture" that is in my parents home. Not totally smooth but not like a knock down either. I tried to recreate it in a small bathroom that had popcorn that I scraped off. I had to do a patch and didn't want to redo popcorn. I ended up doing a knock down. But, I think it's done with a very thick nape roller loaded with thick paint that leaves that type of texture. But I searched YouTube and couldn't find any reference to how to achieve until after I was done....See MoreJoseph Corlett, LLC
