Installation

Concrete Mix
The concrete mix should be an air entrained mix with a minimum of 3,000 psi. All concrete should be placed at the same slump to prevent possible cement shade variations. A 3" to 4" slump is recommended with a 5" maximum. Caution: Do not use any calcium chloride admixtures.

Application
After the concrete has reached the point where no excess moisture shows at the surface, but while still plastic throughout, Dynamicast Color Hardener is applied to the surface by the dry-shake method. Water must not be sprinkled or otherwise added to the surface during application or finishing. The necessary moisture for the color hardener must come from the concrete in order to develop proper bond and assure adequate density for the color-hardened surface. The first shake should consume two-thirds of the material, one third being withheld for the second shake and final touch-up. After the first shake, the surface is thoroughly floated, either mechanically or by hand. It should not be troweled between the first and second shakes. The second shake is then applied evenly and the surface floated and troweled. A small quantity of material should be withheld from the second shake for touching up non-uniform or weak toned areas as necessary. Long handled Frescos must not be used. Hand troweling should be minimized and consistent finishing practices used to insure uniformity of color.

Maintenance

Properly sealed imprinted concrete may be cleaned with most commercial cleaning compounds, detergents, solvents, or mild alkalis with no adverse effect.
