Concrete color release powder is a specialized pigment used to create the desired effect of an antiqued or random antiquing on a stamped concrete floor. It can be applied directly to the surface of fresh concrete or it can be mixed with a liquid release.
Powdered release agents are generally colored, although some white options are available. They are typically composed of cement, iron oxide pigment, and moisture repellant. The mixture forms very fine airborne dust particulates. This prevents the stamp from sticking to the wet concrete, and helps the imprinting tool to remain clean and crisp.
If you’re planning to use a powdered release agent, you will need to cover a large area before stamping. Typically, 30 pounds of powdered release can cover up to 1,000 square feet. To achieve the best results, apply the release evenly with a splash brush.
Once the release has been applied, the pattern will look more natural. It will also add depth to the pattern and make it more realistic. Adding a dark pigment to the release will also increase the appearance of the grooves and corners.
In order to prevent streak marks, it’s important to avoid rolling the release over the concrete. Using a paint roller can help. However, dragging on the release will cause discoloration.
A darker powder release will provide the most realistic coloring. Use a lighter one if you want to create a two-tone effect. When the stamp is completely pressed down, the release color will lighten.
