Epoxy coatings and epoxy sealers provide tough, solvent-resistant finishes to floors, countertops, and decks. In fact, their durability makes them an excellent choice among concrete floor coatings. They consist of an epoxy resin and hardener that combine in a reactive process and then cure to protect the surfaces of metals, wood, and concrete against corrosion and the elements. This variable sealant comes in common applications such as garage floor epoxy, pool epoxy coatings, and industrial epoxy coatings.
