Black Jack® Roof & Construction Sealant is an extra tough, flexible repair compound designed to patch splits, cracks and holes in roof surfaces. This water based patch dries quickly to a non-tacky surface which offers great adhesion to all coatings applied over it. It is designed to repair cracks and holes up to 1"" in width. Black Jack® Roof & Construction Sealant should be used with seam and repair fabric. Black Jack® Roof & Construction Sealant remains flexible while it expands and contracts with your repair, making it ideal to use with all reflective roof products.
