LionGUARD Flashing Cement 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 LionGUARD Flashing Cement the first choice of both roofing contractors and plant engineers. LionGUARD Flashing Cement is composed of selected asphalts, mineral fillers combined with the refined solvent, and special chemical ingredients which give it a unique water displacement quality.

LionGUARD Flashing Cement 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 LionGUARD Flashing Cement.

LionGUARD Flashing Cement is ready to use directly from the container. No heating is required. Spread LionGUARD Flashing Cement by trowel to an average thickness of 1/18" (8 gals. per square) or greater to all surfaces to be treated. To repair large cracks or breaks, spread LionGuard Flashing Cement over the damaged area, then embed LionGUARD Cotton, Glass or Poly-Mat membrane Reinforcement and re-apply another coat of LionGUARD Flashing Cement over the entire patch.

Trowels and other equipment should be thoroughly cleaned with mineral spirits, taking necessary precautions when handling combustible materials.

Do not use near an open flame. Avoid breathing solvent fumes and prolonged contact with skin. Do not take internally. If swallowed, do not induce vomiting. Call a physician immediately. Keep out of reach of children. Keep the container covered when not in use. Do not thin. Dispose of in an environmentally safe manner.
