Traditional high performance floor coating systems require aggressive surface preparation to get good adhesion. They rely on mechanical bonding by absorbing into the pores or rough topography of the surface. Therefore, you cannot use traditional coatings such as epoxy or urethane on polished concrete and in mere days, they’ll peel off. The use of guards or waxes is to maintain the polished surface appearance. However, they need regular reapplication and are vulnerable to stains or chemical etching if you do not clean up spills quickly. Now there is a solution: Coval polished concrete coating!
As the name suggests Coval has a range of coatings that covalently or chemically bond to numerous substrates, especially concrete. They also covalently bond with the hydroxy groups in epoxies and protect them from scratching and staining. Not only is the coating able to chemically bond with the substrate, but it also chemically bonds with itself. This ability to ‘bond with itself’ never goes away. It is an infinite coating system that you can maintain by recoating high wear or damaged areas as needed. Unless the customer wants a different product, there is not a scenario where removing and replacing the coating is necessary. Recoating only requires cleaning the original surface and reapplication. We’ve field tested this coating on several projects for over 10 years and proven its capabilities in harsh loading dock, and restaurant stain environments.
The picture below is a 1500-grit polished finish densified with lithium silicate. Once the densifier was dry, we began spraying the coating over the surface just enough to ‘wet out’ the surface. The surface was dry to touch in 4 hours and forklift ready in 12 hours the next day.
