160.1 Amphibicaulk

Karnak #160.1 Amphibicaulk if a carefully prepared caulking-grade roof cement with special water displacing characteristics, which ensures an effective bond to both wet and dry surfaces. The ability to adhere during inclement weather conditions makes Karnak #160.1 Amphibicaulk the first choice of both roofing contractors and plant engineers. Karnak #160.1 Amphibicaulk is composed of selected asphalt, mineral fillers combined with refined solvent, and special chemical ingredients, which give it a unique water displacement quality.


Karnak #160.1 Amphibicaulk is a cold process, heavy bodied, caulk-grade roof cement ideal for sealing leaks in and around asphalt built-up roofs, joints chimney cracks, skylights, vents, down-spouts and gutters. The dried film retains its flexibility and ductility, so the caulking will resist extreme variations in temperature and weather. Karnak #160.1 Amphibicaulk may also be used to improve wind resistance on low slop shingle roofs.
