Description: Del-Val 303 Premium Fibrated Aluminum Roof Coating is a high performance coating that protects and extends the life of asphalt and metal roof surfaces. Formulated using selected asphalts and blended with high quality aluminum pigments with refined solvents and reinforcing fibers. Del-Val 303 Premium Fibrated Aluminum Roof Coating’s highly reflective surface protects the roof’s surface from destructive overheating and actinic deterioration.
Uses: Del-Val 303 is formulated for applications over new or existing built up roofs, APP, SBS, smooth or granulated surfaces, cap sheet and flashings. It can also be used for masonry surfaces and metal surfaces. DO NOT USE with EPDM, PVC, TPO or other single-ply membranes.
Preparation: Prepare the roof surface by sweeping clean any dust, dirt or debris. Use a wire brush to remove rust from metal. Roof surface must be oil-free and free of moisture both on and beneath the surface. Repair all holes, cracks, blisters, tears or breaks by spreading Del-Val 211 Flashing Cement over damaged area, then embed United Asphalt Cotton or Fiberglass Fabric. Allow repairs to cure 60 days before coating.
Application: Apply Del-Val 303 with a soft bristled brush, paint roller or heavy-duty spray equipment. Product should be mechanically mixed before applying. Spread the product uniformly over the roof surface. Work the coating in one direction. Do not work coating excessively during application as overworking the coating can have a damaging effect on the leafing of the aluminum.
Coverage: Apply at the rate of 1 to 1.5 gallons per 100 sq. ft.
Cleanup: Clean tools with mineral spirits, taking necessary precautions when handling combustible liquids.
