BigOxley Posted August 15, 2015 Report Share Posted August 15, 2015 Recently decided to paint a back room that i don't use. During the painting process, I discovered some loose/peeling paint above the window from what appeared to be water damage. Unfortunately, i had already applied the first coat... wall is plaster and lathe, i believe i think the water was leaking in from the gutter backflowing into the house this last spring, as I haven't never seen the peeling paint on that wall in the 8+ years i have lived here. I have cleaned out the gutter and that's not a problem anymore (i hope) the areas above in red came off very easily. The areas in blue came off with some elbow grease. i need to know what to do now. ... the wall is dry to the touch and no structural damage that i can feel. so far, I've found to clean the wall with a bleach solution and let dry. apply a mildew resistant primer ( i have Bullseye 1-2-3) and then paint after the primer has set. other option: tear down and replace with dry wall..

cstmg8 Posted August 15, 2015 Report Share Posted August 15, 2015 You're going to want to skim that paint line with some mud and sand it flat, otherwise it'll show badly through your new paint. Basically with plaster, just scrape out any loose/bubbled spots and prime/patch them. If your worried about mold inside the wall, that's another story. I'll say that old lathe/plaster walks don't seem to mold as badly as old drywall, but I have no idea what you're dealing with there. Quote Link to comment Share on other sites More sharing options...

cstmg8 Posted August 15, 2015 Report Share Posted August 15, 2015 That sounds like a good idea, it may be fine, but I can't feel good about telling you to cover it up without checking. Hard to tell what kind of insulation is in there. Quote Link to comment Share on other sites More sharing options...

BigOxley Posted August 15, 2015 Author Report Share Posted August 15, 2015 I think I'm going to cut the hole and wait until it rains again. Check for moisture while I'm in there. I would use a brush Brush for the new paint coats? Quote Link to comment Share on other sites More sharing options...
