United Asphalt‘s Armour Proof AP-5100 Moisture Cure Polyurethane is a single component, moisture cure polyurethane roof coating to protect EPDM single-ply membrane, sprayed-in-place polyurethane foam, insulation, wood, metal and BUR substrates. AP-5100 Moisture Cure Polyurethane provides a durable, seamless, flexible, waterproof membrane, resisting lateral movement, shear, and will allow for normal expansion and contraction. AP-5100 offers increased moisture protection through its lower moisture vapor permeability values.
Coverage and Drying Time
Apply AP-5100 at a rate of 1.25 gallons per 100 square feet, according to the substrate and condition. Minimum dry mil thickness shall be 25 mils. Normal drying time is 6 hours to touch, tack free in 8-12 hours. Successive coats must be applied within 48 hours to insure proper adhesion.
