Anvil AquaSeal Waterproofing Sealer is a fast drying, water clean up, environmentally friendly, multipurpose penetrating sealer/primer for vertical surfaces. It may be applied as a stand alone, clear sealer or top coated with elastomeric, latex or oil based coatings. The dried film is resistant to mildew for it contains agents which inhibit the growth of mildew on the surface of the sealer film and is also resistant to acids, and salts. AquaSeal provides a tough and flexible film with excellent scrub resistance and weatherabiliy. May be tinted with latex paint or stain. Mix with equal parts of latex paint for use as a primer. Mix with exterior latex paint to increase its weatherability. May also be used as a binder sealer by adding one gallon of AquaSeal to five gallons of block filler. AquaSeal protects and seals vertical surfaces of Brick, Stucco, Concrete, Grout, Stone, Plaster, Drywall, Adobe, Simulated Brick, Metal, Chalky Surfaces, Terra Cotta Roof Tiles, Asphalt Shingles, Aluminum & Vinyl Siding, Pottery and many other nonporous surfaces. AquaSeal is designed for above grade use only and should not be used on applications exposed to hydrostatic water pressure. Elimination of cascading or ponding water must be addressed prior to Aquaseal application. AquaSeal Waterproofing Sealer has surpassed requirements for water repellency set forth in Fed. Spec TT-C-555B, Section 3.3.3. Remove all dirt, efflorescence, grease, oil, waxes, release agents and peeling pain . If used as a waterproofer on bare vertical concrete two coats are required. Covers 80-300 sq. ft. per gallon depending on surface porosity. For best results apply with a low pressure garden sprayer or airless paint sprayer. Flood coat the surface liberally beginning at the top and allow AquaSeal to run down the surface about 8 inches. For best waterproofing and sealing, back roll the wet coat to uniformly force the sealer into the surface.
