Hi All,
My garage has a concrete floor, and concrete walls up about 4 feet, all the way around. The original owner had the concrete walls covered in skim-coat plaster. About 5 years ago, I painted the garage floor with epoxy paint (the good xylene-based stuff, works great!).... This painting has made the floor watertight, but now moisture in the walls is bleeding through the skim-coat plaster, causing it to flake off the concrete walls. This appears to be a direct consequence of painting the floor (?) I am looking for something to cover the walls with, to prevent the flaking. I could scrape all the plaster off and tile it, but that is a lot of work..... any suggestions? I could use something like hardibacker or such.....
