Epoxies are made of resins whose compositions are perfect as primers, floor finishes, and protective coatings. As epoxy floor coatings, they are therefore used in fire-retardant, waterproofing, and damage-resistant flooring applications.

The chemistry of epoxy makes for epoxy floor coatings that are cross-linked tightly. The coatings film is very resistant to any chemical or toxic intrusion, and even to the seepage of water and air. In metal and concrete surface applications that are prone to corrosion, such impermeability to air, water and chemicals is a positive attribute.

Most epoxy floor coatings nowadays are made from a mix of amine and epoxy. Depending on the mixture level, there are different outcomes to the mix. The amine contributes to glossy surface appearance, better adhesion, faster curing time and better abrasive and toxic resistance. The epoxy levels affect the length of pot life of epoxy floor coatings, as well as provide resistance to almost every kind of damage agent there is — corrosion, water intrusion, acid and alkali permeation, and the effect of humidity.

As intumescent coatings, epoxy floor coatings contain pigments that rapidly expand under high temperatures, forming a thick barrier that provides sufficient protection until the fire is put out by the quick-response fire-fighting team.

Because epoxy floor coatings are so resistant to many types of damages, they are often used for garages, hangars and factory plants. Their impermeability to water makes them particularly useful in areas where water is constantly present, such as pool decks.
