Epoxy coating is a durable protective coating commonly used on concrete, metal, factory floors, machinery and industrial surfaces.

Most epoxy coatings are 2-component systems:

Part A – Epoxy Resin
Part B – Hardener

When both parts are mixed in the correct ratio, they react and cure into a hard, strong protective film.

How Does It Work?

The basic process is:

Mix → Apply → Cure

After application, the coating may become dry to touch first, but it still needs time to fully cure.

Full curing helps the epoxy reach its final:

• Hardness

• Adhesion

• Chemical resistance

• Abrasion resistance

Why Use Epoxy Coating?

Epoxy coatings are popular because they offer:

• Strong adhesion

• Good durability

• Good chemical resistance

• Good abrasion resistance

• Protection against moisture and corrosion

• Smooth and easy-to-clean surfaces

Where Is It Used?

Common applications include:

• Factory floors

• Warehouses

• Workshops

• Machinery

• Steel structures

• Industrial equipment

• Concrete surfaces

Does Epoxy Need a Topcoat?

For indoor use, epoxy can often be used as the final coating.

For outdoor use, a suitable topcoat such as polyurethane may be recommended because long-term UV exposure can affect the colour and gloss of some epoxy coatings.

Important: Surface Preparation Matters

Good epoxy performance depends heavily on proper surface preparation.

The surface should be clean, dry and free from oil, dust, rust or loose coating before application.

For 2K epoxy systems, always follow the correct:

Mixing Ratio + Film Thickness + Application Method + Curing Time

Dry Does Not Mean Fully Cured

An epoxy surface may feel dry before it reaches full performance.

Always refer to the product TDS for the recommended drying, recoating and curing time.

In Short

A good epoxy coating system depends on:

Correct Product + Proper Surface Preparation + Correct Mixing + Proper Application + Full Curing
