155AF Amphibikote (Wet/Dry)

Karnak #155AF Amphibikote is a carefully prepared, emergency 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 #155AF Amphibikote the first choice of both roofing contractors and plant engineers. Karnak #155AF Amphibikote is composed of selected asphalts, mineral fillers combined with refined solvent, and special chemical ingredients which give it a unique water displacement quality.


Karnak #155AF 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.


  • ASTM D-4586 Type I
  • Federal Specification SS-C-153 Type I (AF)


All surfaces should be clean and free from oil, grease, rust, dirt, and other foreign matter. Excess water should be removed if possible before application of Karnak #155AF Amphibikote.
