Installation

Preparatory Work
The mixing shall conform to ASTM C94, the portland cement ASTM C150, and the coarse and fine aggregates ASTM C33. Color addition should not exceed 10% of the weight of the cement conforming to ASTM C979.

Application
A power mixer should be used to provide thorough mixing and dispersing of color. To provide consistent and uniform color a sound method is: (1) Load the mixer with selected mix design of portland cement, coarse, and fine aggregate. (2) Add the designated amount of DCS Cement Color by weight along with the cement for the mix and agitate at full speed for several minutes. Any change in proportioning the amount of water, aggregate, sand and color to the cement and/or type of cement and aggregate used on the same job can result in variation of color tone in the finished job.

Before loading, agitator should be checked for residual water from cleaning.

Maintenance

After the concrete has cured for a period of at least 28 days various “proprietary sealers” may be used for protection against the elements. Please check with the sealer manufacturer for aesthetic changes the sealer may cause to the appearance of the Colored Concrete Surface.
