Lucas #8000 100% Silicone Roof Coating* is a 98% solids moisture-cure coating intended for the repair and restoration of asphalt, modified bitumen, metal, concrete, TPO, PVC, KEE(Fibertite), Hypalon (CSPE), PIB, and EPDM roofs. Silicone’s low water absorption allows for improved ponding water resistance. Fast cure time allows for same day recoating. Lucas #8000 is low odor, and contains no solvents or water, so it will not freeze! VOC compliant in all of North America. #8500 is a thicker mastic version of #8000 for repairs. When installed in white, #8000 will reflect solar energy and reduce interior building temperatures while improving the efficiency of rooftop air conditioning units.
APPLICATION
Mechanically mix prior to application. Surface to be coated must be dry and free of dirt or corrosion particles. Clean with Lucas #115 Universal Wash. EPDM roofs in particular require aggressive power washing and may need to be cleaned twice to remove all surface contamination. Thoroughly rinse the roof after cleaning to remove all detergent. All seams, fasteners and penetrations should be sealed with silicone sealant. Apply base coat of #8000 at a rate of 1 gallon per 100 sq. ft. Allow coating to cure, typically 2 to 4 hours, then apply second coat at the rate of 1 gallon per 100 sq. ft. For best results, apply coating in a multi-directional fashion. Use #8000 as it comes from the container, no thinning is necessary with this product.
This product cures through absorption of moisture from both the substrate and the air. Avoid entraining air when mixing. Cure time will be faster in humid conditions and on substrates that hold moisture such as concrete. Open and partially full containers will skin over quickly. If this occurs, remove the skin and continue using the remaining product
CAUTION
Avoid prolonged contact with skin or fumes. If irritation occurs seek medical attention. Keep out of reach of children
