APV Engineered Coatings has made available BLOCKSEAL, a water-based, waterproof liquid flashing that seals window and door substrates in new and existing residential, commercial
and industrial applications. It meets and exceeds AAMA 714-19, “Voluntary Specification for Liquid Applied Flashing Used to Create a Water-Resistive Seal around Exterior Wall Openings in Buildings”. BLOCKSEAL Liquid Flashing is a low-VOC, fast-drying acrylic adhesive. Its high-resin content provides adhesion to the substrate, eliminating any possibility of moisture penetration. BLOCKSEAL can be applied to weathered wood, shakes, plywood, clapboard, primed metal, galvanized metal, urethane, polyester, adobe, brick, stucco, masonry, slate and slab. It also can be installed on concrete, including green concrete that has set but has not appreciably hardened.
