APOC 109 asphalt roof cement is a durable, all weather, long-lasting leak repair designed to be applied in wet or dry applications such as patching splits, cracks and seams in spudded gravel, mineral surfaced cap sheet and smooth surface asphalt roofs, as well as composition shingle roofs. APOC 109 can also be used in vertical applications and will not sag. It can be used for sealing around chimneys, vent pipes, gravel guards, down spouts, cracks in concrete and more. APOC 109 is also an excellent utility mastic for use below-grade in heavy-duty foundation waterproofing and damp-proofing systems.
