Although urethane or epoxy coatings offer stain resistance, the maintenance is much more difficult. The protective coat can be damaged if you cut directly on it or place intense heat on it. Further, markings caused by this are difficult to repair, and vapours from the product are harmful. This is why Molded Stone Studio chooses to use a food-safe penetrating reactive sealer that gives off no VOC’s. This sealer offers stain protection, reasonable heat protection, and scratch protection while allowing the surface to retain the unique texture of concrete.
