Overview
Epoxy floor coatings are the standard answer for industrial and commercial floors that have to withstand traffic, chemicals, aggressive cleaning and heavy abrasion. They are hard, chemically resistant, easy to clean and, in the self-levelling grades, visually excellent.
The Delshine range covers the full spectrum: thin-film solvent-based coatings for light-duty areas, solvent-free high-build systems, self-levelling floor coatings, anti-slip orange-peel textures for wet and oily areas, decorative 3D art systems, and the antistatic and static-conductive grades required in electronics, pharmaceutical and chemical environments.
The floor is the substrate where preparation matters most. Concrete floors are routinely coated without ever being ground, and a floor coating will then delaminate at the first sign of traffic. Grinding, moisture testing and correct primer selection are not optional steps.

How it works in the coating system
Floor coatings are applied to concrete and are the only coating system in the range where the substrate preparation matters more than the coating itself.
Concrete is a porous, alkaline, moisture-carrying substrate with a weak dusty surface layer. A floor coating applied without mechanical preparation will lift, and there is no primer that reliably fixes this. Grinding, moisture testing and joint repair are the foundation of a floor that lasts.
Purpose in the system: Applied over a mechanically prepared concrete slab, normally as a primer plus one or more build coats.

Surface preparation
- Test the concrete for moisture vapour emission before coating. A coating applied over a slab that is releasing moisture will blister, and no amount of primer will fix it.
- Grind or shot-blast the surface to remove laitance and open the concrete. A floor that has never been ground will not hold an epoxy coating under traffic.
- Repair all cracks, spalls and joints with a rigid or semi-rigid repair mortar matched to the movement characteristics of the joint.
- Remove all oil, grease and contaminants; shot-blast areas contaminated with oil.
- Vacuum the surface thoroughly and perform a final dust elimination with an air blower or tack cloth immediately before priming.
- Check that the concrete is at least 28 days old and that its surface temperature is at least 3 °C above the dew point.
Application procedure
Grind or shot-blast the slab to remove laitance and open the surface, then repair all cracks and joints.
Apply the primer by roller or squeegee, working it into the prepared surface and taking care not to leave thin patches.
For self-levelling systems, mix and pour within the pot life and spread with a notched squeegee or spike roller, working from the furthest corner towards the exit.
Install the specified anti-slip aggregate by broadcast into the wet topcoat for traffic areas.
Mixing, ratio and induction time
Mixed at the stated ratio, typically 3:1 to 5:1 by volume, with a full induction period before application. For self-levelling systems, mix only what can be placed within the pot life — usually enough for 15 to 20 minutes of working time.
Cure, recoat window and service readiness
Foot traffic after 12-24 hours, light forklift traffic after 3 days, full chemical resistance after 7 days and full cure after 21-28 days at 20-25 °C. Heavy point loads should not be placed on the floor for the first week.
Coverage and thickness calculation
Self-levelling systems are specified at 2-3 mm total build, which at 100% solids means 2-3 litres per square metre. Thin-film systems are specified at 0.2-1 mm across one or two coats. Confirm both the build and the coverage per litre.
Technical note. Coverage (m²/litre) = (volume solids × 10) / DFT (µm)
Worked example
| Specified DFT | 1000 µm |
|---|---|
| Volume solids | 95 % |
| Theoretical coverage | 0.95 m²/litre |
| Total for the area | 100 m² → 95.0 litres |
Advantages
- Very high mechanical and abrasion resistance, far beyond painted or sealed concrete.
- Excellent chemical resistance to oils, fuels, alkalis, detergents and cleaning agents.
- Seamless, monolithic and easy to clean, with no joints to harbour dirt.
- Self-levelling grades produce a flat, attractive surface with no roller marks.
- Antistatic and static-conductive grades provide a controlled path to earth for explosive and sensitive environments.
- Solvent-free formulations available with very low odour and near-zero VOC.
Limitations and precautions
- Surface preparation is the single biggest factor in the performance of a floor coating and is routinely under-budgeted.
- Moisture in the slab will cause blistering; a moisture test is mandatory.
- Full cure takes time — a floor cannot be returned to traffic immediately, and heavy loads can imprint the surface if placed too early.
- UV exposure will amber and eventually discolour standard epoxy floors, which is why aliphatic polyurethane or polyaspartic topcoats are used in sunlit areas.
- Epoxy floors are slippery when wet unless an anti-slip grade or aggregate broadcast is specified.
Storage and shelf life
- Store component A and B in their original sealed containers in a cool, dry, ventilated store between 5 °C and 35 °C.
- Keep the hardener away from moisture and direct sunlight.
- Do not allow the components to freeze — freezing destroys the hardener.
- Rotate stock first-in-first-out and observe the labelled shelf life, typically 12 months unopened.
Safety, PPE and ventilation
- Epoxy hardeners are skin sensitisers. Wear nitrile gloves, safety goggles and protective clothing and change gloves frequently.
- Use an organic-vapour cartridge respirator when mixing or applying in enclosed or poorly ventilated spaces.
- Ensure good ventilation and wear knee pads and protective footwear for the grinding and preparation work.
- Wash skin immediately with soap and water if contact occurs.
- Collect grinding dust and coating waste for proper disposal rather than washing it into drains.
Quality control and inspection
- Carry out and record a moisture vapour emission test before any coating is applied.
- Measure the system DFT at multiple points across the floor.
- Perform pull-off adhesion testing on the completed system and against the specified minimum.
Pricing and how to order
Delshine quotes this product per square metre at a specified dry film thickness, or per drum/litre depending on the project. The material cost is usually the smallest part of the installed cost — surface preparation, access and application labour dominate. Send us the substrate, the service conditions and the required DFT and our technical team will return a full system recommendation with a firm price.
Epoxy floor coatings are priced per square metre at a specified build, and preparation is normally the largest single cost. A 1,000 m² self-levelling floor at 3 mm needs roughly three drums of coating plus primer, aggregate, abrasive discs and labour. The specification should always include preparation and moisture testing, because those are what determine whether the floor lasts one year or ten.
Frequently asked questions
The questions below are the ones our technical team is asked most often about this product family.
What is the difference between self-levelling and thin-film epoxy floor?
A self-levelling floor coating is a high-build, low-viscosity system that flows out to a flat, level surface during application — typically 2-3 mm. A thin-film system is applied in a much lower build of 0.2-1 mm with one or two coats and is much more dependent on the quality of the substrate. Use self-levelling where appearance, hygiene or heavy traffic matter, and thin-film where budget and a basic sealed floor are the requirement.
Do I need to grind my concrete floor before epoxy?
Yes. Grinding removes the laitance — the weak dusty top layer that separates from the slab — and opens the pores so the primer can key into the concrete. Acid etching is not an adequate substitute for a floor that will carry traffic. Diamond grinding to a fine profile is the industry standard for a floor that has to last.
What is the anti-static epoxy floor coating used for?
Antistatic and static-conductive floor grades are used in electronics manufacturing, semiconductor cleanrooms, pharmaceutical production and chemical handling areas where electrostatic discharge could ignite a sensitive component or an explosive atmosphere. The conductive grade provides a controlled path to earth and typically requires an earth connection and a conductive primer. The two grades differ in surface resistance, so specify the target resistance value.
How long does an epoxy floor take to cure?
Foot traffic after 12-24 hours at 20-25 °C, light forklift traffic after 3 days, full chemical resistance after 7 days, and full cure after 21-28 days. Heavy point loads and pallets should not be placed on the floor for the first week. In cold conditions every one of these figures extends, which is why floors should be coated in a controlled temperature window.
Can epoxy flooring be applied over an existing epoxy floor?
Sometimes. If the existing floor is sound and not peeling, it can be abraded, cleaned and overcoated with a new epoxy system. If it is delaminating or contaminated, it must be removed mechanically. Test the adhesion on a trial area and check for amines, which can cause a plasticising effect at the interface.
What is the anti-slip orange-peel topcoat?
It is a self-levelling epoxy formulated with a fine aggregate or a texturing agent that creates a controlled textured surface. The texture gives mechanical grip in wet or oily areas where a smooth floor would be dangerous, while keeping the coating far easier to clean than a full aggregate-broadcast system. It is the usual specification for commercial kitchens, workshops and wash-down areas.
