I am planning to install a ceramic backsplash above my laminate counter top in the kitchen over the painted drywall. What kind of treatment is needed for the drywall so that it does not get moist? Also, a quick step-by-step procedure would help a lot, too. -Raj
You should be able to tile right over your existing drywall with no problem. Once the adhesive dries and the grout has set, it will be imperious to moisture.
Good luck with your project,
