Keeps working when the competition fails.
Other protectants stop working in as little as 10% humidity. The problem with that is the EPA recommends keeping indoor humidity between 30% and 50% rendering other mold protectants useless. Superstratum Smart Polymer Coating is activated by humidity eliminating mold and mildew long after the other protectants fail.
Superstratum also does not wash away in water like other protectants providing years of guaranteed protection.
