For decorative concrete contractors, choosing between powder and liquid release agents is a key question. The choice may be based on a number of factors, such as the aesthetic vision at work and the environment in which the stamped concrete will be installed.

Liquid releases are a popular choice for indoor applications because they evaporate on their own, eliminating the need to wash them off after stamping. This makes them a better option when stamping in areas with sensitive surfaces such as near pools.

In addition, they are typically less messy to use than powder. They also are good at adding texture to stamped concrete, though not all projects will be able to benefit from this feature.

Whether you choose to use powder or liquid, it is important to thoroughly clean the surface before applying. This prevents contaminates from interfering with the imprint quality.

It is also necessary to clean the patterned stamps or texture mats from time to time. This can be done by spraying with water.

If the surface is to be antiquated, the powder should be wiped off the surface before sealcoating or it can recontaminate the imprint. This can be done by spraying it with water, but it should be done before the patterned stamps or texturing skins are placed on the surface.

The best method for applying concrete liquid release is to use a dry tampico brush and flick the release on in a light, uniform layer. Too much of the product can interfere with the pattern imprint, especially if the surface is lighter in color.
