Epoxy Floor Coating
Epoxy is a durable, long-lasting floor coating solution that, once applied in liquid form and cured, acquires high resistance to water, acids and alkalis. Thanks to its high-strength structure it is easy to clean and does not lose its resistance over time. These properties make epoxy floor coating one of the most widely chosen solutions in both industrial and decorative areas.
During application, epoxy passes from a liquid to a solid state as it cures and reaches its final hardness. As well as being durable, it offers an attractive appearance and is used in many fields, from wind turbine blades to boatbuilding. In floor coating applications there are various types of epoxy that can be tailored to different requirements:
Types of Epoxy Floor Coating:
Self-Levelling Epoxy Coating: A type of epoxy that spreads by itself and forms a smooth surface.
Antistatic Epoxy Coating: A coating that controls electrical conductivity, used particularly in industrial areas.
Multilayer Epoxy Coating: Offers high durability with its multi-layered structure.
3D Epoxy Coating: A type of coating used for decorative purposes, adding depth and visual interest to floors.
Orange-Peel Epoxy Coating: A coating chosen for its anti-slip surface and attractive appearance.
Clear Epoxy Coating: A type of epoxy that protects the materials beneath and offers a natural appearance.
Advantages of Epoxy Floor Coating:
High Durability: Provides superior protection against water, acids and alkalis.
Easy Cleaning: Hygienic and easy to clean thanks to its smooth surface.
Long-Lasting Protection: Offers a durable solution that does not lose its resistance over time.
Various Areas of Application: Has a wide range of use, from industrial facilities to decorative areas.
Attractive Appearance: Adds elegance to the space with different design options.
Fast Application: Completes your projects within a short time with practical application methods.

Application Areas of Epoxy Floor Coating
Food and beverage production facilities — production lines requiring hygiene and ease of cleaning
Pharmaceutical and cosmetics factories, clean rooms and laboratories
Automotive and machinery manufacturing workshops — floors exposed to oil, solvents and mechanical loads
Warehouses and logistics centres — large areas under forklift traffic and racking loads
Hospital, outpatient clinic and operating theatre corridors
Car parks, showrooms and commercial spaces
Types of Epoxy System and Thicknesses
Clear Primer and Impregnation (0.1–0.3 mm)
This is the thinnest system, penetrating the pores of the concrete to reduce dusting and consolidate the surface. It is low in cost, but chemical and mechanical protection is limited. It is chosen as an economical solution in warehouses and plant rooms.
Thin-Film Coating (0.3–1 mm)
This is a coloured coating applied by roller or trowel. It seals the surface, makes cleaning easier and provides moderate chemical resistance. It is suitable for areas with light to moderate traffic.
Self-Levelling System (1.5–3 mm)
This is a system in which a flowing resin spreads by itself to form a smooth surface. It offers high visual quality, a seamless appearance and good chemical resistance. It is the standard solution for food, pharmaceutical and laboratory applications.
Trowel Mortar and Quartz-Filled Systems (4–9 mm)
This is the system with the highest mechanical strength, in which resin is mixed with quartz aggregate and applied by trowel. It is used in production areas with heavy impact, dropped pallets and intensive forklift traffic.
The Application Process
1. Floor testing: The surface tensile strength, relative humidity and flatness are measured. The coating thickness and system type are finalised on the basis of these data.
2. Mechanical preparation: The cement laitance is removed by shot blasting or diamond grinding to obtain an open-pored surface. This is the stage that most affects the life of the coating.
3. Repair and anchor grooves: Cracks are filled with resin and voids are made good with repair mortar. Anchor grooves are cut at the foot of walls and around outlets to prevent the coating lifting at the edges.
4. Primer and quartz broadcast: An epoxy primer is applied; in thick systems quartz is broadcast over the primer to increase mechanical keying.
5. Body coat and top coat: Application is carried out in successive coats according to the system thickness. A spiked roller is used for deaeration. In areas requiring slip resistance, aggregate is broadcast before the top coat.
6. Curing and return to service: Approximately 24 hours is allowed for foot traffic, 2–3 days for vehicle traffic and 7 days for full chemical resistance.
Technical Notes and Standards
The tensile strength of the concrete surface should generally be above 1.5 N/mm² ; at lower values the floor is improved first.
High relative humidity in the concrete causes blistering and debonding in epoxy coatings; a moisture-barrier primer or a moisture-tolerant system may be required.
Screeds and floor mortars are classified under TS EN 13813, and surface protection systems under TS EN 1504-2 .
Epoxy can yellow over time under UV; a polyurethane top coat is recommended outdoors and in areas receiving plenty of light.
During application the ambient temperature should generally not fall below 10 °C; curing stops at low temperatures.
Frequently Asked Questions
How many millimetres should an epoxy floor be?
The load in use determines this. In areas for foot traffic and hygiene, a 1.5–2 mm self-levelling system is sufficient. If forklift traffic is heavy, 3 mm and above is recommended, and 4–9 mm trowel mortar where there is a risk of heavy impact and dropped pallets. Thin systems are more economical but have a shorter life.
Does an epoxy floor crack?
Epoxy is a rigid material; if the concrete beneath cracks, the coating follows that line. For this reason existing cracks are filled with resin before application and moving joints are carried through into the coating. On floors where movement is expected, polyurethane is more suitable.
Is there an odour after coating?
A resin odour is noticeable during application and in the first hours of curing. In solvent-free systems this odour is markedly less. Once curing is complete no odour remains; solvent-free products are preferred in food and healthcare facilities.
Does the choice of colour affect performance?
It does not affect performance, but it makes a difference in use. Light colours improve lighting efficiency and make spills visible; dark colours conceal dirt. In production areas, different colours are also used to distinguish zones.
