Concrete Release Agent: What Are the Different Types, and How Do They Work?

Working with stamped concrete isn't as easy as with staining or decorative coatings. It requires a lot of work in a fixed timeframe and needs to be meticulously planned ahead to get the job done right. One of the key processes needed to achieve a perfect stamped concrete project is the application of the concrete release agent. This product, which can be found in powder or liquid form, is used to prevent stamping mats from bonding to the concrete underneath and ruining the imprint. Release agents also give a subtle tint to the concrete that adds to its rustic hues. Be careful of wind conditions that may blow the powder to other surfaces, leaving a tint and needing cleanup.

Powdered release agents are usually applied at a rate of 3 pounds of agent per 100 square feet. The application technique is done using a brush that is coated evenly with the powder then flicked onto the concrete surface using the wrist. A thin, even layer of the concrete release agent is needed to keep the surface from sticking to the pattern without leaving too much color on the concrete.

Using liquid release agents require different tools and application processes. Use a pump sprayer to coat the concrete with an even layer of the release agent. You can use tinted liquid release agents, but make sure to mix the tint a couple of days prior to application. This makes sure that all the color particles have dissolved in the release agent and prevents the color from clumping in certain areas once the agent is applied. Mix the color in thoroughly, and shake the sprayer from time to time to keep the particles from settling.
