Interior Waterproofing

PermaDri coatings provide a quick and easy solution for interior waterproofing and corrosion protection projects around the house including: shower pans, tile underlayment, and virtually any other surface.

PermaDri coatings are cold-applied using a brush, roller, or trowel. The rubberized coating adheres to virtually any surface including tile, concrete, wood, metal, foam and more. The coating typically cures within 24-48 hours (depending on application thickness, temperature, and relative humidity).

PermaDri coatings have impressive elastomeric qualities: the cured membrane can elongate up to 850% with 95% recovery.  Thus, the coating will expand and contract as a result of thermal changes.

PermaDri coatings are environmentally-friendly and safe to apply which makes them an ideal resource for indoor projects. PermaDri coatings are excellent for interior projects because…
