For exterior use only. Protective clothing and eyewear should be used during application of this product. Always apply on a clear, warm sunny day. Premix individual components (A and B) separately before combining. Then, in a separate pail, mix Part A and Part B in equal amounts. Use a mechanical drill to ensure proper mixing. Once mixed, product must be used within 30 minutes. Pot life 2 hours at 75°F. Dry to touch in 1 hour, full cure 24 hours. Apply in morning hours to allow maximum cure time. Application should be completed a minimum of 4 hours prior to sunset. Surface temperatures must be between 50°F and 130°F. Apply with long nap (3/4″ to 1″) exterior paint roller for porous surfaces like concrete block and use a short nap (1/4″ to 3/8″) for smooth surfaces like metal. This product should not be spray applied. Higher humidity, thicker films, poor air flow and lower temperatures will increase dry times.
