Ten Things You Need to Know About Epoxy Floor Coatings
For half a century, epoxy formulations have been an important part of the construction industry. In particular, epoxy floor coatings are widely-used in floor applications. Here are some things about one of the most significant coating materials in nature that you may or may not yet know:
- The secret behind high-performing epoxy coatings is epoxy resins.
The main materials of quality formulations, such as epoxy-based primers, top-coats, and sealants, are epoxy resins. These resins allow the performance of epoxy floor coatings as well as floor finishes, protective coats, fire retardants, waterproofing, and paints that are damage-resistant.

- In several surface forms, epoxy coatings are applicable.
Specific flooring applications require specific coating systems determined primarily by the type of substrate material used. One of the few systems that can work in concrete , steel and almost all forms of surfaces is epoxy floor coatings.
- Molecules of epoxy resin are cross-linked, so they are almost impermeable.
The unusual chemistry between the organochlorine / epoxide compounds of bisphenol A and epichlorohydrin induces a reaction when exposed to amines that produces cross-linked epoxies. The resulting epoxy floor coatings are extremely resistant to water, chemical or air intrusion — a vital capacity for metal or concrete surfaces that are vulnerable to corrosion.
- Epoxies for improved efficiency may be mixed with other materials.
Some of the popular coating systems produced in tandem with epoxy include epoxy-amine systems, epoxy-sulfide systems, aliphatic epoxy systems, and hybrid epoxy systems. Glossy surface appearance, improved adhesion and faster curing times are achieved with amine. Alkydes and acrylics also work well with epoxy coating systems.
- Heavy duty floors can be covered by epoxy floor coatings.
Many kinds of damage are immune to epoxy coatings. No wonder that they are mostly used in places where harm-inducing agents are continuously displayed, such as production plants, factory floors, garages for heavy machinery and aeroplane hangars.
- Coatings made of epoxy have remarkable adhesive properties.
Epoxy-based coatings have strong adhesive capabilities—1.5 thousand pounds per square inch of flooring adhesive strength. This applies to floors that can stay intact for longer periods of time and even under heavy physical loads and in good shape.
- Strong fire-retardants are epoxy coatings.
Certain epoxy floor coatings contain pigments that, when exposed to extreme heat, expand rapidly. This expansion forms a thick defence layer that lasts long enough for the fire to be put out naturally or by a fire-fighting team that responds.
- Epoxy floor coatings are either water-borne, solvent-borne, or high-solids.
On many surfaces, water-borne epoxies are effective, while high-solid formulations cover a wider area of application and contain lower concentrations of VOC. Solvent-borne epoxies are an older technology yet produce a harmful odour and are high in VOCs. The latter also takes more time for care and longer post-cleanup operations.
- Floor coatings made of epoxy can present health and environmental hazards.
As a possible health threat, the bisphenol A compound in epoxy resins is currently under investigation and solvent-based coats contain high levels of VOCs that are toxic to the environment and to application staff.
- They have their share of weaknesses with epoxy coatings.
To prevent problems during healing time, epoxy floor coatings are very dependent on a clear mix ratio. To ensure consistency in texture and viscosity, applicators must obey the manufacturer ‘s guidelines. When exposed to UV rays and to temperature changes during the mixing, application and curing phases, the coatings are also fragile.
