KARNAK 155 Amphibikote is a cold process, heavy bodied, trowel applied emergency roof cement ideal for repairing leaks in asphalt built-up roofs, flashing on walls, chimneys, skylights and vents, down-spouts and gutters. The dried film retains its flexibility and ductility so the coating will resist extreme variations in temperature and weather.

Preparation & Application

Although it can be applied underwater for emergencies, it is best if all surfaces are clean, dry and free from oil, grease, dust, dirt, loose paint or foreign matter.

KARNAK 155 Amphibikote is ready to use directly from the container. No heating is required. Spread KARNAK 155 Amphibikote by trowel to an average thickness of 1/8” (8 gals. per square per coat) or greater to all surfaces to be treated. To repair large cracks or breaks, spread KARNAK 155 Amphibikote over the damaged area, then embed KARNAK 34 Cotton, 31 Glass or 3036 Poly-Mat membrane Reinforcement and re-apply another coat of KARNAK 155 Amphibikote over the entire patch.
