Preparation
Surfaces must be clean, dry, and free of oil, grease, soil, efflorescence, dust, or laitance. Power washing of the surface is advised and any repairs must be made prior to application. Once the surface has been cleaned, it must be dried, and any rinse water should be removed by flushing down a drain (if permitted) or with a vacuum. A simple test to ensure proper dryness is to place a rubber mat on the floor overnight. If no visible moisture or darkening of the mat is observed, then the surface is dry enough to coat.

At this point, a small mock-up area should be applied in an inconspicuous location to test the compatibility of the coating with the prepared substrate. Allow the coating to dry and cure fully, then inspect for proper film formation, gloss, and adhesion. Confirm that the film is free from whitening or any other defects.

Mixing
The material is ready for use and requires no mixing or dilution. It is unlawful to further dilute with non-exempt solvents.

Application
AK-2 WILL DARKEN CONCRETE.

New Concrete Application
Finish trowel and allow surface water to completely dissipate. Use a low pressure (20-30 pounds) sprayer or power sprayer and apply uniformly at the specified rate of coverage (below). Avoid heavy accumulation.

Existing Concrete Application
Use a long nap applicator or a paint roller to distribute the compound more evenly. Back rolling is highly recommended. Avoid heavy accumulation. An airless sprayer or low pressure spray equipment may be used on larger application areas. Apply a second coat to surfaces that are very porous and where absorption is rapid. Allow the coating to become tack-free between coats.
