Whether you're looking to create a color accent on a concrete floor or protect the surface of your concrete, you may want to consider a concrete release agent. These products can help you to prevent urethane mats from sticking to the surface of your concrete and even help to prevent staining.
Various release agents have been produced. These are formulated with active ingredients, detergents, additives, wetting agents and other substances. These are designed to release formwork from hardened concrete.
One example of a release agent is a polydimethylsiloxane (PDMS) concrete release agent. It contains siloxane in a range of about 0.001% to 0.1% by weight. The PDMS is present in compositions in which vegetable oil is the principal constituent.
The release agent can also be formulated using mineral oil without a solvent. This form of concrete release agent contains nanoparticles. These nanoparticles can be in powder or sol/gel formulation. They are supposed to reduce the incidence of "bug holes" in concrete.
Another form of release agent is a mold release agent. It is applied to the molds of pre-finished concrete parts. The molds can be either plastic or steel. The release agents are rolled or sprayed on the molds. These agents are designed to be applied in a layer of 10 to 50 mm.
Creating color accents with a release agent
Using a concrete release agent, such as Proline's Dura-Liquid Release, can help add color accents to your concrete project. This release agent also promotes the release of tools and texturing tools on your project, keeping them from sticking to the surface of the concrete.
Release agents come in liquid and powder forms. Liquid releases are used in indoor applications and powders are used for stenciled concrete projects.
Liquid release agents can be applied directly to the surface using a pump-up sprayer. These release agents act as bond breakers, preventing concrete stamps and tools from sticking to the concrete surface. Using a release agent also helps keep the stamped pattern from settling and puckering.
Powdered release agents, on the other hand, can be applied to both stenciled concrete and stamped concrete projects. These release agents are composed of iron oxide pigments that add color accents to the surface of the concrete.
The darker release agent works best over a lighter base color. Darker pigments create a shadow effect, making the corners and grooves look deeper. They also help the pattern look more realistic.
Preventing staining of concrete
Using a concrete release agent is one way to prevent staining from occurring. This is because release agents act as a thin barrier between the concrete and pattern. They also prevent the concrete from sticking to the pattern.
These types of release agents are usually water-based, which means they don't release volatile organic compounds that contribute to smog. They are also made from plant-based materials.
Choosing the correct release agent is important because it must be safe for concrete. They should not contain diluents, additives, or other compounds that might harm concrete. They must also not contaminate the surface with VOCs, which are gases that contribute to smog.
There are several types of release agents, including reactive and chemically active. Reactive agents are attracted to metals and wood, while chemically active agents produce a thin chemical membrane that blocks concrete from entering the wood pores.
These release agents are usually applied in powder form. They are then flicked onto the concrete surface with a brush. They can also be mixed with water. They are usually applied at about 3 pounds per 100 square feet.
