Quick Application Guide
Per Square (Per Coat)
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.
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 Del-Val 211 Flashing Cement over damaged area then embed United Asphalt Cotton or Fiberglass Fabric. Allow repairs to cure 60 days before coating.
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. 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.
Apply at the rate of 0.5 to 1 gallon per 100 sq. ft.
