I have a 1958 basement. Walls have been painted & spotted with flex seal over the years. Have had water issue in past but that has been resolved and fixed. Looking to just cleanup the basement corner by sump pump. Water stains etc someone referred drylock but I am hesitating because I read drylock does not adhere to already painted walls and will peal & cause more of a mess. What steps would you take for this project. thank you.
If your water leaks have been fixed then there is no reason to use dryloc, instead to seal out the existing water stains use a heavy coat of Pigmented Shellac Sealer Primer… afterwards you can finish coat all the walls with ordinary acrylic paint, but choose a high grade brand like Sherwin Williams or Behr…
Good Luck
