About this product
MajorSeal Liquid Flashing is designed to waterproof difficult flashing conditions. The MajorSeal Liquid Flashing System offers an alternative to traditional flashing technology. Kit includes two 10 ounce tubes of M-Bond Sealant; one roll Topcoat flashing fabric (6" x 50'); one pair disposable gloves; and one notched trowel/wet mil gauge. MajorSeal Systems combine MajorSeal Liquid Flashing and United Coating Roof Mate Fabric to form a durable, redundant flashing membrane. MajorSeal Liquid Flashing is easy to install. Compatible substrates include concrete, masonry (uncoated block and brick), wood, EFIS, and granule-surfaced BUR and SBS cap sheets. In addition, MajorSeal Liquid Flashing is compatible with most metals (excluding Kynar coated metals and copper). Do not use on APP or single-ply membranes such as EPDM, PVC, or TPO. MajorSeal Liquid Flashing is designed for use with hot asphalt or heat-welded applications.
