I have a situation where the interior paint is peeling in several rooms, most notably the bathroom. The paint blisters then peels. You can peel the paint away in sheets right down to the drywall. The drywall is left in perfect condition, basically as if it were never even painted. I'm assuming it is a moisture issue. It has been extremely humid this summer and the house is not air conditioned. How do I prevent this from continuing? What do I do to the areas already effected? We are currently in the process of adding central AC.
Hmmm, some possible problems may be, 1. The walls were not properly prepped for paint.(ie:washed, primed etc) 2. The walls were moist when they were painted. 3. There was a thin layer of wallpaper glue from the past on the walls. If the walls were prepped right, washed down, PRIMED, and then painted with a GOOD quality paint, this should not happen, no matter how much humidity is in the house. If the moisture is from the other side of the walls or condensation in the walls themselves thats a different story. I lived in a very humid city for years ( with no air also) and really didnt have a problem. Anyway, all you can do is either scrape the remaining paint off, and feather the edges on sections that wont come off , to smooth it down. If it is a matter of the walls not being properly prepared then no matter what you do, the remaining paint, if there is any left, may still peel off in the future. Best thing to do is prime the remaining wall areas and repaint.
If you can remove all of the paint off the walls in this bathroom that will the best as if any remains it can peel and take the new paint with it. Then you will need to wash the walls with TSP and bleach to remove dirt and mildew and allow to dry a couple of days before painting. Then you will want to prime the walls with an ACRYLIC primer such as Zinsser 123,you want an acylic not just latex as it will be more resistant to the moisture and adhear better. The finish paint should be either a satin/eggshell or semigloss and idealy one designed for bathrooms as they are made for this enviroment. Be sure to apply 2 coats of finish over the primer.
Hope this helps out.
If you don't have one think about installing a exhaust fan to help remove the moisture from your bathroom.
Hope this helps out.
