Lucas Silicone Roof Coating #8000 – High Solids – Full Range

100% silicone based Lucas #8000 is a single part roof coating that creates a barrier that is resistant to natural weathering, is durable, breathable, watertight and weatherproof. Lucas #8000 can be applied over spray applied polyurethane foam, EPDM, PVC, aged acrylic coatings, concrete, asphalt BUR, granulated modified bitumen, and metal roofs. Lucas #8000 has excellent primerless adhesion to many surfaces when tested in accordance with ASTM D 6694.

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.
