Existing concrete surface is to be shot blasted, diamond ground, or other approved method of roughing the surface to accept adhesion of the refinishing products. Any of these processes shall have a dust collection system to keep all airborne dust to a minimum. After all surfaces have been roughened, the entire surface is to be cleaned free of all dust and foreign matter that would compromise adhesion. Any existing low, irregular, or rough spots shall be leveled to provide a uniform, smooth surface prior to the application of the actual finishing products. This shall be followed by application of a base coat into which ceramic chips of a color to be determined will be broadcast and spread onto the surface. This shall be followed by a final clearcoat of the polyaspartic finish coat. Consideration should be given to providing a moderately nonslip finish that is still easy to keep clean. If a contractor has an alternative coating available, or another process other than what is previously listed, it should be listed as an option and priced separately. The finished surface shall not be affected by water, chlorides, petroleum products of any kind, acids, alkalies, and abrasion due to vehicular tire traffic. The surface should not stain, fade, or delaminate, and be able to be easily cleaned by conventional methods and detergents.
