How is decorative concrete colored?
There are two methods to color decorative concrete. Using the first method, color is spread onto the surface by hand using the dry shake method, then worked into the surface using hand tools. After the color is applied and worked into the fresh cement, a release/hardener is applied. The release/hardener serves a duel purpose. It adds a tremendous amount of strength and it highlights and acts as a second color, which gives the stamped pattern and overall color a defining and distinguished look. The second method used is when the color is mixed directly inside the concrete at the concrete plant and mixed inside the truck. The concrete is colored throughout from the top to the bottom instead of just 1/4″ into the surface. The release/hardener is applied using this method as well. The second method tends to be slightly more expensive since the cost of the material will increase. Both are good methods, one is not better than the other.
