Extreme Deck Waterproofing


Cold-applied, self-adhering waterproof system for decks and balconies over occupied living spaces.

The Extreme Deck Waterproofing System combines Strataflex sheet membrane with SubSeal® liquid membrane to provide a durable waterproofing system that accepts a variety of decorative hard surface flooring materials. It is a thin, low profile (50 mils dry), double layer of waterproofing protection for decks and balconies with extreme weather exposure from 20°F to 145°F.

The Extreme Deck Kit conveniently packages 2 gallons of SubSeal® liquid membrane with companion products, NAC TAC primer (blue), pre-formed inside/outside fabric corners, seam tape and NAC approved polyurethane sealant. The kit, when paired with two rolls of Strataflex sheet membrane, covers a 300 sq ft deck or balcony and makes the Extreme Deck Waterproofing System one of the most durable and complete systems on the market.
