Thanks very much for your help

Answer 1

i would recomend going to your local  home depot or lowes and asking what they recommend to do or cut a hole and get  a patch kit at home depot or lowes

Answer 2

id reccomend the following steve;

1. Knock out any loose plaster with a cold chisel and ball-peen hammer. Clean out the plaster in and behind the lath to provide a surface to which the new plaster can adhere. Brush the area clean, and dampen it with a sponge for better adhesion.

2. If the hole is smaller than 2 inches across (but larger than a fine crack, nail hole, or small gouge), fill it with a single layer of patching compound, and finish as described in Step 4. For larger holes, apply a first layer using a 6-inch broad knife.

3. Score the patch with a nail, and then allow the surface to dry. Moisten the patch, and then apply a second layer of patching compound, coming within 1/8 to 1/4 inch of the surface. Score the patch, and let it dry.

4. Apply the final coat, feathering the edges an inch or so beyond the edges of the hole. Scrape a straightedge across the wet finish coat to remove any excess material. When the patch is dry, sand and spot-prime.And then paint that wall Steve !!!!

hope i helped you out pal

Answer 3

I have made relatively small patches on plaster walls using Polyfilla with great success. Just make sure you break away any loose areas that haven't fallen out yet, & try to correct the orriginal cause of the damage if you can.

Answer 4

Hi Steve,

   Back tracking, I'm not sure I'd agree with the parallel wall Q answer, but that's old news.

   I'm not at all a fan of plaster. I find it archaic in 2008, but work with it or against it often.

   I want to disagree with one answer who suggested a radical approach, as in maybe taking it down to the "Lathe."

   More, though I might want to address the WHY of the issue, and has it been resolved?

   Certainly even a poly blend MUD can solve the problem, as in drywall, the base substance is gypsum, and the same FINISH efforts will apply.

   Still, I'd want to not only know the initial cause and possible resolutions in that regard, but the extent of the damage NOT SEEN so obviously. I was born in the dark, but not last night. It sounds to me like water intrusion.

   Not knowing at all your agreement with the client, I might want to make this a Time and Materials job.

Answer 6

You will need to sand all the flakes off and apply some more plaster first if it look like it needs it.

Answer 7

Take a spackel knife or a puddy knife chip away all the flakey stuff make it a smooth surface as possible

Then spackel over the area that is damaged a good spackeling job is the key to making it look good

Prime the area then paint it good luck
