Epoxy Floor Coating
An epoxy coating requires a clean and slightly porous surface for it to adhere properly. Epoxy may not bond to sealed or polished concrete. The concrete also must be fully cured. Before applying epoxy floor coating, it is important to patch and repair all major cracks and chips in the concrete surface and to remove all grease.
If the concrete is old, test the surface for previous layers of epoxy or other products that might have been applied over the years. To test for sealant, pour a small amount of water onto the floor. It should soak in. If the water beads on the surface rather than soaking in, it likely has been sealed and may not be suitable for an epoxy coating.
Before applying an epoxy coating, make sure that the temperature is suitable, and follow all manufacturer’s recommendations. Unfavorable temperatures can cause the epoxy to bubble and peel. Epoxy is a two-part liquid that you mix before application. Once the product is mixed, you have a limited time to apply the epoxy coating before it starts to harden.
