Description: Del-Val 301 Silver Seal Non-Fibered Aluminum forms a durable protective metallic shield that extends the life of asphalt and metal roof surfaces. Formulated using selected asphalts and blended with high quality aluminum pigments with refined solvents. This formula is non-destructive to asphalt based roofing membranes and has great moisture and heat-resistant properties.
Uses: Del-Val 301 Silver Seal Non-Fibered Aluminum is formulated for applications over new or existing metal, built up roofs, APP, SBS, smooth or granulated surfaces, cap sheet and flashings. 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 and 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 Flashing Cement over damaged area then embed United Asphalt Cotton or Fiberglass Fabric. Allow repairs to cure 60 days before coating.
Application: Apply 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. Overworking the coating can have a damaging effect on the leafing of the aluminum.
Coverage: Apply at the rate of 0.5 to 1 gallon per 100 sq. ft.
Cleanup: Clean tools with mineral spirits, taking necessary precautions when handling combustible liquids.
Code Approvals/Compliance: This product meets or exceeds the requirements of ASTM D-2824 Type I
Precaution: Do not thin, heat container or store in an area where temperatures exceed 120°F. Do not apply if there is a threat of rain or due in 24 hours. Applying Del-Val 301 Silver Seal Non-Fibered Aluminum directly over hot applied asphalt can result in alligatoring. Allow roof to cure thoroughly before coating.
