Epoxy Resin Floor Costs UK — What to Charge to Lay Resin Flooring in 2026

What Resin Flooring Is and Where It's Used

Resin flooring is a liquid-applied system that cures into a seamless, jointless surface bonded directly to the substrate — usually a concrete slab. It is poured, rolled or trowelled on site, so there are no tiles, grout lines or board edges to fail. Once cured it is chemical-resistant, dust-free, and extremely durable. The two main chemistries are epoxy and polyurethane (PU), often used together in a single build-up.

The most common jobs you'll be asked to price are:

• Garages and garage conversions: the single biggest source of domestic resin work — both functional garages and garages turned into gyms, workshops or hobby rooms.
• Workshops and warehouses: hard-wearing, easy-clean floors that take forklift and trolley traffic.
• Home gyms and showrooms: decorative flake or high-gloss finishes where appearance matters.
• Commercial kitchens and food units: anti-slip, hygienic, often HACCP-driven PU screeds that resist heat and grease.
• Some domestic interiors: open-plan kitchens, utility rooms and hallways where a poured polished or microcement-style resin is wanted.

Resin Floor Systems and What to Charge Per m²

There is no single "resin floor" price — it depends entirely on the system specified. Thickness, chemistry, number of coats and finish all move the number. Here are the main systems with current UK supplied-and-fitted rates.

Thin-Coat / Roller Epoxy (Floor Paint Systems)

The entry-level system: two or three coats of epoxy applied by roller, typically 0.3–0.5mm total film thickness. It transforms a tired concrete garage floor into a clean, sealed, easy-to-sweep surface at a low price point. It is the most-quoted garage system because it hits the budget most homeowners expect.

Be honest about its limits: a roller-coat system follows the substrate, so a pitted or cracked slab still looks pitted, and it will not bridge defects. It also wears faster than a built-up system under heavy point loading. For a smooth, sound slab it is excellent value; for a poor slab it is the wrong spec.

• Supplied and fitted: £30–£45/m²

Self-Levelling / Self-Smoothing Epoxy

A poured epoxy applied at 2–3mm that flows out to a flat, seamless, mirror-smooth finish. This is the "proper" resin floor most customers picture — high-gloss, jointless and tough. Because it is poured at thickness it evens out minor undulations in the slab and gives a far more durable, impact-resistant result than a roller coat.

It demands a flat, sound, dry substrate and careful prep — any pinhole, contamination or moisture issue shows up dramatically in a poured floor. Price it for showrooms, gyms, retail and quality garage conversions.

• Supplied and fitted: £45–£70/m²

Polyurethane (PU) Screeds and Comfort Floors

Polyurethane systems are more flexible and more thermally and chemically resistant than epoxy. Heavy-duty PU screeds (4–9mm) are the standard for commercial kitchens, food production, breweries and cold stores — they tolerate thermal shock from steam cleaning and hot spillage that would craze an epoxy. PU is also used as a UV-stable topcoat over epoxy to stop the yellowing that epoxy suffers in sunlight.

• PU topcoat over epoxy: £50–£75/m²
• Heavy-duty PU screed (commercial kitchen / food unit): £70–£100/m²

Decorative Flake and Quartz Systems

Decorative systems broadcast coloured vinyl flakes (chips) or coloured quartz aggregate into a wet epoxy base, then seal with one or more clear coats. Flake systems are popular in garages and gyms because they look good, hide minor imperfections and the texture adds slip resistance. Quartz systems are thicker, tougher and used in commercial and wet environments.

• Flake (chip) system: £45–£70/m²
• Quartz broadcast system: £60–£90/m²

Anti-Slip Finishes

Anti-slip is achieved by broadcasting fine aggregate (aluminium oxide, silica or quartz) into the topcoat. It is essential for ramps, commercial kitchens, wet processing areas and anywhere with a slip-risk assessment. The cost uplift is modest in materials but the textured surface is harder to clean, so spec the slip rating to the use rather than maxing it out everywhere.

• Anti-slip uplift on a standard system: +£5–£15/m²

Floor Prep — Where the Job Is Won or Lost

Resin failures are almost never the fault of the resin. They are prep failures. The bond is only as good as the surface it's laid on, and the single biggest reason installers lose money — and pick up callbacks — is underestimating prep. Build prep into every quote as its own line, not an afterthought.

Mechanical Preparation (Grinding / Shot Blasting)

The slab must be opened up to give the resin a key. Diamond grinding removes laitance, old coatings, paint and contamination and leaves a profiled surface; shot blasting is faster on larger industrial floors and gives an aggressive mechanical key. Either way, never bond resin to a sealed, polished or contaminated slab — it will delaminate. Mechanical prep also generates dust, so factor in extraction and waste removal.

Crack and Joint Repair

Cracks, spalls, blow-holes and pop-outs need cutting out and filling with a resin repair mortar, and movement and saw-cut joints need treating appropriately before the floor goes down. Skipping this telegraphs every defect straight through a poured finish.

Moisture and Damp Testing

This is the prep step most often skipped — and the most dangerous to skip. Resin is impermeable. If the slab has no damp-proof membrane (DPM) or the moisture content is too high, water vapour rising through the slab pushes the resin off in blisters, sometimes weeks after handover. Test relative humidity (a hygrometer / digital RH probe to BS 8203 / BS 8204) before you commit to a system. If the slab is too wet you need a surface DPM (an epoxy moisture-suppression primer), which adds cost but saves the whole floor.

Priming

A primer seals the prepared slab, controls porosity and stops pinholing and outgassing in the body coats. On a high-moisture slab the primer doubles as the DPM. It is cheap insurance — never lay a build-up straight onto bare ground.

• Diamond grinding / shot blasting: £8–£20/m² depending on slab condition
• Crack and joint repair: priced by length / extent, allow a contingency
• Moisture-suppression DPM primer (if slab is wet): +£10–£25/m²
• Standard priming: usually included in the system rate

Prep can easily be 30–50% of the total job cost on a poor slab. A clean, new, dry power-floated slab needs little; a 40-year-old oil-stained garage with no DPM needs a lot. Inspect before you price.

What a Garage Resin Floor Costs

Garages are the bread and butter of domestic resin work, so it pays to have benchmark figures ready. Sizes vary, but a typical single garage is around 15–18m² and a double is 30–36m². The total depends on the system chosen and how much prep the slab needs.

• Single garage (roller / flake, sound slab): £700–£1,200
• Single garage (poured or heavy prep): £1,200–£1,800
• Double garage (roller / flake, sound slab): £1,200–£2,000
• Double garage (poured, decorative or heavy prep): £2,000–£3,000

Small jobs carry a minimum charge. Mobilising plant, mixing materials and the day's labour cost roughly the same on a small garage as a slightly larger one, so most installers set a floor of around £650–£800 regardless of size. Quote the minimum charge openly so customers with a tiny utility room understand why the per-m² rate looks high on small areas.

Coats, Drying and Curing Time

A resin floor is a sequence of coats, and each one needs the right interval before the next goes on. Rushing the recoat window traps solvent or moisture and causes blistering; leaving it too long means you have to abrade between coats to get adhesion. Build the timeline into your quote so the customer knows the space is out of use for several days, not a single visit.

• Primer: typically overcoat after 6–16 hours.
• Body / pour coat: recoat window usually 12–24 hours.
• Topcoat: light foot traffic after roughly 24 hours.
• Full chemical and mechanical cure: up to 7 days — keep vehicles, heavy point loads and washdown off until then.

Temperature matters: most resins want the slab and air above 10°C to cure properly, which is why unheated garages slow right down in winter. Cold curing extends your timeline and can ruin the finish — quote winter garage jobs with realistic durations or supply temporary heating.

What Affects the Quote

Two resin floors of the same square metreage can differ by thousands of pounds. The variables that move your price most are:

• Substrate condition: a sound, level, dry slab is cheap to prep; a cracked, oil-soaked, uneven or previously coated slab is expensive. This is the single biggest swing factor.
• Moisture: no DPM or high slab RH means a moisture-suppression primer and a higher build — never absorb this cost, price it in.
• Area size: larger floors carry lower per-m² rates because mobilisation and minimum charges spread out; small rooms hit the minimum charge.
• Finish and system: a roller coat is a fraction of the cost of a poured decorative quartz floor with a UV-stable PU topcoat.
• Access and downtime: upstairs, tight access, working out of hours so a commercial unit can stay open, or demolition of old flooring all add cost.

Always inspect and test the slab before you quote. Pricing a resin floor off a photo or a phone description is how installers end up doing free prep, swallowing a DPM, or worse — laying over a wet slab and stripping it back out under warranty.
