Coverage and Drying Time
Apply AP-3300 at a minimum rate of 1 to 1.25 gallons per 100 square feet per coat, according to the substrate and condition. Two coats are recommended. If applied over the Armour Proof AP-3100 Acrylic Base Coat, then a minimum of one coat is recommended. A minimum of 18 mils DFT is recommended to achieve optimal performance of the coating. Normal drying time is 2-4 hours. Armour Proof Coatings recommends applying AP-3300 by airless spray in multiple coats in a crosshatch pattern. This will avoid pinholes and insure a uniform film build. Backrolling may be necessary. Refer to the Armour Proof Coatings Specification for detailed instructions.
