ALDOSEAL 750 is a high quality, high solids, acrylic elastomeric seam sealer designed to bridge and seal seams, gutters, vent pipe flashings, air conditioning units and expansion joints for all types of roofing substrates. ALDOSEAL 750 has excellent weatherability and ultraviolet resistance. ALDOSEAL 750 also offers a flexible, durable sealer with excellent resistance to mechanical or chemical attack.
ALDOSEAL 750 should be applied only to clean, dry, sound surfaces free of loose particles or other foreign matter. Over metal surfaces that show signs of oxidation, rust should be removed by wire brushing if necessary after pressure washing. A primer is required over such areas, as well as over areas that may have existing caulking.
