For roofing contractors seeking a non-fibered aluminum coating that offers reliable protection and reflectivity while being non-destructive to asphalt-based roofing membranes, Del-Val 301 Silver Seal Non-Fibered Aluminum from United Asphalt provides a quality solution. This coating is formulated using selected asphalts blended with high-quality aluminum pigments and refined solvents, creating a durable, protective metallic shield upon application. It is specifically designed to be non-destructive to asphalt-based roofing membranes and possesses great moisture and heat-resistant properties. The reflective surface of Del-Val 301 protects the roof’s surface from destructive overheating caused by solar radiation and damaging actinic deterioration (UV exposure), helping to extend the roof’s lifespan.
Del-Val 301 Silver Seal Non-Fibered Aluminum is formulated for versatile applications over new or existing metal roofs, built up roofs (BUR), APP and SBS modified bitumen, smooth or granulated surfaces, cap sheet, and flashings. Important: This coating is NOT suitable for use with EPDM, PVC, TPO or other single-ply membrane roofing systems.
Proper preparation is crucial for optimal performance. Prepare the roof surface by sweeping clean any dust, dirt or debris. Use a wire brush to remove and rust from metal. The 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 301 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.
Apply at the rate of 0.5 to 1 gallon per 100 sq. ft., providing a thinner application rate compared to fibered coatings. Do not apply if ambient temperature will drop below 32° F in a 24-hour period or dew will settle before coating is allowed to dry. This product meets or exceeds the requirements of ASTM D-2824 Type I, confirming its quality and suitability as a non-fibered asphalt-based aluminum coating. Clean tools with Del-Val Orange Cleaner & Degreaser or mineral spirits. Important precautions include: 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 dew in 24 hours. Applying Del-Val 301 Silver Seal Non-Fibered Aluminum directly over hot applied asphalt can result in alligatoring; allow the roof to cure thoroughly beforehand.
