What is the difference between concrete sealers and concrete coatings? A sealer is usually classified as a penetrating solution that will lock out moisture, mold, mildew and efflorescence leaving a natural looking concrete slab. A coating on the other hand is usually classified as an industrial strength solution that is built up on top of the concrete protecting through layers of material. Concrete coatings are excellent choices for warehouses, food prep kitchens, aircraft hangers, laboratories and shop floors to name a few. When looking for an industrial strength concrete coating you want to make sure the coating has excellent hardness, protection from abrasions and uv rays while also having chemical resistance properties and being extremely adherent.
The first step to take when thinking about a concrete coating is preparation. You need to make sure the coating can adhere to the surface so it is recommended to use a floor grinder like an EDCO grinder or a Clark floor machine commonly found at big box retail outlets with at least an 80 grit pad. Once the surface is ready for application, an epoxy concrete primer like Epoxy 325 is the best option for a high build floor. It will add a protective layer aiding in better adhesion for the next coat in the system.
