Key Features & Design

• 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.
