Products / Karnak 160.1 Amphibicaulk (Wet and Dry)

Karnak 160.1 Amphibicaulk is a caulking-grade asphalt roof cement with water-displacing ingredients so it bonds to wet or dry surfaces. The maker lists it for sealing leaks around built-up roofs, joints, chimney cracks, skylights, vents, downspouts and gutters, and to improve wind resistance on low slope shingle roofs. Its product page lists ASTM D4586 Type I Class I and Class II, ASTM D3409 and Federal Specification SS-C-153 Type 1. It is sold in 10.1 oz caulk tubes, 48 per case.
