There are many types of release agents for use in concrete, including powder and liquid releases. Powdered release agents are used before the final troweling stage of a project. The agent is flicked onto the surface of the concrete with the wrist.

Liquid releases are easier to work with and require less cleanup. They must be mixed thoroughly, so they do not settle. In addition, it is best to use a pump sprayer to apply them.

It is important to select a form release oil that is non-corrosive and mild. It should also be free of waxes. If a form has a waxy surface, you can use a rag to wipe it off.

A dark pigment can be added to the release agent to create a more realistic look. However, it can affect the quality of the imprint.

To prevent the color of your concrete from fading, use a thin, even layer of release agent. You can apply the release in the grout lines, or in the lower recesses of the pattern.

During the stamping process, the remaining release agent will be depressed into the surface paste. This will allow sealer to adhere. Once the stamp is completely pressed, the release color will lighten.

It is important to remember that too much release agent can make the pattern look choppy and uneven. For this reason, the quality of the release agent is a major factor in the appearance of your finished project.
