Shower Waterproofing
A non-toxic, watertight coating for home bathrooms and commercial shower rooms, proven to last for decades.
Shower Waterproofing
Our shower waterproofing coating keeps bathroom and shower enclosures completely watertight, in the home and in demanding commercial settings alike. Made from plasticized gypsum with zero VOCs, it is non-toxic, breathable, and safe for the people using the space every day.
The performance behind it is remarkable. Our coating carries an ANSI/NSF 61 potable water contact rating, the same standard used for drinking water systems, and has withstood more than 20 years of continuous brine submersion with no measurable deterioration. If it can survive two decades underwater in salt water, it will keep your shower watertight for the long haul. It waterproofs while still allowing surfaces to breathe, which prevents the trapped moisture and mold that plague sheet membranes, liquid membranes, and foam systems.
From a single home bathroom to the shower rooms and locker rooms of a gym or health club, we deliver a seamless, fully bonded waterproof barrier. Because the coating bonds to itself, repairs restore a fully watertight surface without tearing anything out. Pair it with our basement floor coatings for complete moisture protection throughout your home.
