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.
USES
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.
SPECIFICATION
ASTM D-4586 Type I
Federal Specification SS-C-153 Type I (AF)
SURFACE PREPARATION
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.
APPLICATION
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.
CARE OF TOOLS
Trowels and other equipment should be thoroughly cleaned with mineral spirits, taking necessary precautions when handling combustible materials.
CAUTION
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.

LionGUARD Premium Fibered Aluminum Coating is made of selected asphalts and pigment flakes of pure aluminum, blended with petroleum solvents and mineral fibers. When LionGUARD Premium Fibered Aluminum Coating is applied to the roof, the aluminum flakes leaf to the surface, forming a reflective, metallic shield over the base material.
The advantages of this metallic aluminum shield are twofold:
The asphaltic oils in the base coating are protected from harmful intense rays of the sun by the reflective properties of the aluminum. Over 50% of the sun's rays are reflected by this aluminum shield, thereby preventing these oils from being "cooked" out of the base coating. The coating, therefore, retains its resilient characteristics and will not prematurely crack or dry out.During the hot summer months, LionGUARD Premium Fibered Aluminum Coating will help reduce indoor building temperatures and improve inside living and working conditions. LionGUARD Premium Fibered Aluminum Coating prevents the sun's rays from penetrating the roof coating and passing the heat into the building interior.
The combination of these protective materials-aluminum, asphalt and reinforcing fibers - by the exclusive LionGUARD process results in a self-protecting roof coating with longer-lasting moisture and heat resistant features. LionGUARD Premium Fibered Aluminum Coating remains tenaciously bonded to the base material, thus assuring longer roof life, with subsequent savings on roof maintenance.
SURFACE PREPARATION
All surfaces should be clean, dry and free of dust, dirt, oil and other foreign matter. Repair all cracks and blisters. New asphalt roof surfaces should weather a minimum of 90 days before being coated with LionGUARD Premium Fibered Aluminum Coating. However, LionGUARD Premium Fibered Aluminum Coating can be coated on roofs 5 to 7 days after LionGUARD asphalt emulsions have been applied.
APPLICATION
LionGUARD Premium Fibered Aluminum Coating should be spread uniformly over the roof surface. Care should be taken not to overwork the coating during application. This could have a damaging effect on the leafing of the aluminum. Pour the correct amount of aluminum coating to cover a given area and apply uniformly. Be sure to mechanically mix the aluminum coating thoroughly before using. LionGUARD Premium Fibered Aluminum Coating can be applied with a soft roof brush, roller or spray.
COVERAGE
Apply at the rate of 1 to 1.5 gallons per 100 sq.
CARE OF TOOLS
Tools and other equipment should be thoroughly cleaned after use with mineral spirits, taking the necessary precautions when handling combustible materials.
CAUTION
Do not use near 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 container covered when not in use. Do not thin. Dispose of in an environmentally safe manner. Cover air intakes during application and while drying.

Available in 5 gallon pails.
