How do I repair a lathe and plaster wall?
Answers:
I just did some repairs to some lath and plaster this morning. You need to pick off any "loose" pieces at the edges of your existing hole. Your 1 foot by 3 foot repair may become larger! It's tough to know when to stop. When you feel you have removed the most loose pieces, it's time to start the repair. You need to purchase some "setting type" joint compound. It comes in a powder that you add water to, and mix to a consistancy that is slightly thinner than peanut butter. It should'nt sag when applied to the wall. Fill the area and put some mesh tape over the edges. The joint compound that you purchase should be a 90 minute setting type. This means it will be dry within that time and you can reapply some more to finish it. I would also suggest using a regular joint compound to "feather out" and finish the area. It's easier to sand. This job is a little tricky. It takes alot of practice to get familiar with the tools and to get a good feel for the material. If you apply the joint compound evenly and smooth at each coat, you should have minimal sanding only after the last coat is applied. Good luck (If you have to remove to much plaster I would suggest screwing on a piece of 1/4 inch drywll in the area.)

i would carefully cut it out and replace it with a piece of drywall.....if only the finish coat is off then you can use plaster to smooth it out

go to home depot
Clean up the crumblies and vacuum up around it. Put some wire lath behind the hole attaching it to the wood lath or whatever is there. Cover with several coats of a mixture of joint compound and plaster of Paris 70/30. I like to use the fiberglass joint tape when I get close to the finished level. Finish off with a few layers of joint compound. Or ask Home Depot.
sounds like scaling this is a chemical reaction you need to find the source of the leak once that's dint seal the area kilz will work this will stop anymore from crumbling i start with a product called structolite use this as your base pushing into the lath to make new keys make sure this layer is below the top layer of plaster this sets like concrete then after this sets you can use topping to finish plaster is a art so if you like to get a good finish call someone we still use lathe ans blue board to plaser with.good luck
