Armor Plate 901 may be applied with a brush, roller, or spray equipment. If spray equipment is used, allow 2-4 hours for the thinner solvents to evaporate before pouring concrete.
When bonding new concrete to old concrete, apply Armor Plate 901 to the old concrete surface just prior to pouring the new concrete. DO NOT allow AP 901 to cure before pouring new concrete. As long as AP 901 is tacky to the touch, good adhesion will be attained. If AP 901 cures prior to pouring the new concrete, apply another coat of Armor Plate 901 onto the cured coating.
When using AP 901 bonding agent, new concrete may be poured in thin layers (1/4″ to 1/2″) to create a “feathered edge”.
Cure time will vary with the temperature, humidity and service conditions. The chart below indicates a typical cure cycle for AP 901.
