Roof-Master 220 All Weather Flashing Cement is a unique high-quality flashing cement that has been manufactured using the highest quality chemical ingredients available. Its flexible, smooth, trowel consistency makes this product ideal for patching emergency holes and cracks in roofs. Roof-Master 220 All Weather Flashing Cement is ideal for sealing emergency leaks on both wet and dry roof surfaces and has excellent underwater adhesion.

Uses

Specially formulated for use in damp, wet roofing situations, Roof-Master 220 can be used as a heavy duty flashing cement for repairing flashings, asphalt shingles, built-up roofs, metal and masonry surfaces. Great for sealing leaks and openings at flashings (chimneys, vents, skylights, metal joints, gutters). DO NOT USE with EPDM, PVC, TPO or other single-ply membranes.

Preparation
