Epoxy flooring
Roller-applied or self-levelling epoxy floors: seamless and easy to clean, for factories, warehouses and facilities.
What it is and how it works
Epoxy flooring is resin layers applied to a mechanically prepared concrete slab, forming a continuous, hard, easy-to-clean surface that resists abrasion, oils and many chemicals.
Systems range from thin roller coats to self-levelling and sand-broadcast systems for heavy wear and slip resistance; the choice follows traffic, chemicals and the cleanliness required.

Where it fits — and where it does not
A good fit for
- Factories and warehouses
- Showrooms, service centres and commercial facilities
- Plant rooms and technical areas
- Laboratories and clean areas, with self-levelling systems
Not a fit, or needs a check
- Slabs with rising moisture or no vapour barrier, unless a moisture-tolerant system is used
- Outdoor areas in the sun: epoxy yellows and chalks
- Slabs with moving cracks or no joint planning
- Food-processing floors that need specialist hygienic systems
Advantages and limitations
Every system has strengths and limits; the right choice starts from the site conditions.
Advantages
- Seamless and easy to clean
- Abrasion and chemical resistance
- Colours, markings and anti-slip textures
Limitations
- Moisture in the slab causes blisters or debonding
- UV causes yellowing: indoors, or with a UV-resistant top coat
- Can be slippery when wet without texture
System build-up
Top to bottom. Final thicknesses and materials follow the approved specification and the product TDS.

Top coat
Sets the gloss, slip resistance and cleanability.
Per system
Epoxy body coatCore layer
Roller-applied for thin coatings, or self-levelling for a thicker, smoother floor.
Primer
Penetrates and consolidates the concrete; may be followed by a scratch coat.
Prepared slab
Ground or shot-blasted, clean, and with moisture within the product limit.
Preparation and application
Surface preparation
- Slab moisture tested (e.g. ASTM F2170 or ASTM D4263)
- Mechanical preparation by grinding or shot-blasting
- Cracks, joints and holes repaired
- All dust removed
Application sequence
Primer
A penetrating epoxy primer, sometimes sand-broadcast.
Repairs and scratch coat
Filling and levelling where needed.
Body coat
A roller coat, self-levelling or broadcast layer, per the system.
Top coat
The sealing coat in the chosen colour and texture.
Joints and markings
Joints re-cut and sealed; lines marked.
Curing
Protected until it can take traffic.

Checks and common mistakes
Quality checks
- Moisture test record before the primer
- Surface profile accepted
- Thickness or consumption per area
- Visual check: no pinholes, bubbles or colour streaks
- Pull-off adhesion where specified (ASTM D7234)
Common mistakes
- Skipping the moisture test
- Acid etching or light sanding instead of proper preparation
- Wrong mix ratio or poor mixing: soft or sticky spots
- Coating over expansion joints
Common questions
How is peeling prevented when epoxy is installed?
With mechanical preparation that opens the surface and removes dust, a moisture check of the slab before starting and a suitable primer — most peeling comes from poor preparation or vapour pressure from the slab. See the problem page.
Can epoxy be used outdoors?
Standard epoxy yellows and chalks in the sun; outdoor areas need a UV-resistant system.
Can epoxy go over existing tiles?
Sometimes, if the tiles are well bonded and mechanically prepared with a suitable primer — but the grout lines may show through. Usually the tiles come off and the epoxy goes on the concrete after an adhesion check.
Is an epoxy floor slippery?
A smooth gloss finish can be slippery with water or oil, so anti-slip aggregate is added on ramps, wet areas and walkways, depending on the use.
