APOC Rain-Proof 0.9-Gallon Fibered Waterproof Cement Roof Sealant AP-1091

Rain-Proof® Wet/Dry Roof Cement is a flexible, all-weather cement especially adapted for wet surfaces in adverse or colder weather conditions. APOC® 109 is designed and formulated for the professional contractor and is manufactured with select asphalt, solvent and fibers to provide a long lasting, durable patching compound. APOC® 109 can be used to patch splits, cracks and seams in spudded gravel, mineral surfaced cap sheet and smooth surface asphalt roofs as well as composition shingle roofs. It will seal areas around chimneys, vent pipes, gravel guards, down spouts, cracks in concrete and expansion joints on roofs. APOC® 109 is also an excellent utility mastic for use below grade in heavy duty foundation water-proofing and damp-proofing systems.
