Lucas #1044 Sunscreen™ White Elastomeric Roof Coating is an acrylic elastomeric roof coating intended for application to metal, concrete, EPDM, Elvaloy/PVC, polyurethane foam, asphalt BUR and granule surfaced roofs. A high degree of rubber-like elasticity allows this product to accommodate wide swings in temperature and significant building movement.
Lucas #1044 is formulated from elastomeric acrylic polymers. #1044 is supplied in highly reflective white and sandstone tan. This is a water-based material and must be kept from freezing.
This product comes in a white color.
Mechanically mix before using. Do not store above 90ºF. Apply only at temperatures above 40ºF and rising with less than 90% humidity and no threat of rain for 48 hours. Surface temperatures should be under 100ºF to avoid premature curing. If roof surface is hot, apply a light water spray to reduce its temperature.
The roof should be power-washed clean with Lucas #115 Universal Wash. All metal roof fasteners should be inspected and loose, broken or missing fasteners replaced. All seams and fasteners should be sealed with Lucas #4500 100% solids SemiSelf-leveling Sealer or #1500 Acrylic Mastic prior to coating the roof. Cracked areas should be reinforced with Tietex fabric. The surface must be clean and free of loose or flaky rust and paint. Rusted areas should be pre-treated with Lucas #1025 Rust Inhibiting Primer.
Apply with a roller or suitable spray equipment at the rate of 1.25 gallons per 100 sq. ft. A second coat of #1044 is required to achieve a consistent, pin-hole free, surface approximately 20 mils thick. Drying time to first top coat @ 70ºF is 2 to 4 hours.
