I started a job for a neighbor, using Peel Away I to take layers of old paint off the 70-year-old plaster walls, because it has repeatedly peeled and cracked after a max of two years. What I found underneath was a series of cracks in the plaster, sometimes with paper and fiber mesh tape in the layers, that obviously didn't help. I intended to apply a couple of layers of joint compound, then primer and paint, but I'm not sure anymore that this will solve the problem. Can anyone help?
I think you are on the right track. The only suggestion I would make is to pre-moisten the plaster with a spritz of water before applying the skim coat. This should help adhesion. You could add a 1/2 cup vinegar or acetic acid, per 2-gallons of water, to neutralize the stripper, but it probably is not necessary. As long as the plaster is adhered to the lath you should be fine.
