Powder Concrete Release Agent Powder release is used with stampable overlays, stamped concrete and wall stamp mixes. It creates a barrier between the wet cement and the stamping tool and prevents the stamping tools from creating "puckers" at the surface that greatly detract from the finished product. The color mixed in the release is pressed into the deeper recesses of the stamp profile. Powder release will provide the rich contrast between the concrete's base color and the release's secondary color. The resultant two tone adds to the realistic look and desired antique effect for many different patterns. The grout lines of grouted patterns will always reflect the powder release color in the preferred sharp contrast to the more dominant base color. The most realistic coloring is achieved through the application of a darker powder concrete color than the base color of the concrete. Contains integrated iron oxide pigments that simultaneously provide a secondary accent color to the concrete surface. When cured the cement is washed or acid washed to remove the bulk of the release but leave the release color in the recesses of the pattern. Coverage rate is approximately 700 to 1,000 sq. ft. per 30 lb. pail.
