Why buyers specify it
- Seamless and non-porous — no grout, no joints and no skirting gap for spillage to enter
- Continuous coved upstand (R ≈ 50 mm) at the wall base and around bench feet
- Typical resistance to dilute acids, alkalis, salts, detergents and alcohols in daily use
- Splash-and-spill tolerance sized to real laboratory behaviour: wipe-up time, not immersion duty
- Fine broadcast texture available for wet areas and sinks — specified by location, not by taste
- Low-odour, near-zero-VOC build-up so bays can be phased around a working laboratory
A seamless 2–3 mm epoxy floor for laboratories and QC suites: non-porous, coved at the wall base, and built to take daily splash and wipe-down with detergents and dilute acids and alkalis without a joint to attack.
Product overview
A seamless, cove-able resin floor for laboratories and QC suites: 3 mm poured at 2.2 kg/m² per mm, semi-gloss with a fine texture, mixed A:B = 4:1 by weight from a 20 kg set (15 kg resin + 5 kg hardener). It holds >80 Shore D and 78 MPa compressive with 3 MPa adhesion and a Taber loss of ≤0.03 g (CS-17, 750 g load, 500 revolutions). 35 minutes of pot life at 20 °C, walk-on at about 24 hours, return to full service at 7 days.
What actually destroys a laboratory floor
What destroys a laboratory floor is rarely a tipped drum — it is the cracked beaker at the sink that sits for twenty minutes, the mop bucket carrying more bleach than intended, and the junction where the floor meets the wall. A seamless resin floor with a coved upstand removes that last weak point, and a dense non-porous film gives you minutes before a spill has to be wiped.
Chemical resistance, stated as a spec and not as a chart
We state our resistance as categories with contact time and a verdict, not as a reagent table we have not measured. Send us your actual chemical list and we confirm in writing which ones this floor is specified for. That is not a hedge: a generic resistance chart circulated between laboratories is usually drawn for a different resin, a different film thickness and a different cure age than the floor you are buying. What we need is the exposure — which reagent, what concentration, how long it stands, and how often — because a splash wiped within the hour and a pool left overnight are different specifications.
The same honesty applies to appearance. Bleach and sunlight change the colour of an epoxy film long before they change its strength, and a floor that has been promised as colour-stable in a room that is mopped with hypochlorite weekly will disappoint on schedule.
The schedule is the number that closes a laboratory
- Walk-on at about 24 hours on this build. A laboratory is released bay by bay, so a day is the planning unit rather than an evening.
- Hard-soled traffic, benches and trolleys come in after that, and chemical resistance is only fully developed at the 7 day mark.
- Work around a live building is the normal case: a low-odour, near-zero-VOC build-up with a French A+ emission classification is what lets a floor be phased while the rest of the suite keeps running.
Where it is the wrong pick
A room that needs static control is a different build — see our cleanroom and GMP antistatic system. A floor that has to survive a wash-down bay with hot water or a cold store is not an epoxy conversation at all. And an existing laboratory floor that is sound but does not want lifting can be overlaid rather than removed — the over-existing-tile system is the one specified for that. Send the room list, the reagent list with concentrations, the cleaning protocol and the dates the laboratory has to stay in service.
What actually destroys a laboratory floor is not a drum of acid tipped over it — it is the everyday: a beaker cracks at the sink and the spill sits there for twenty minutes, the mop bucket carries a stronger dose of bleach than anyone intended, and reagent dust and solvent vapour work at the one place the floor meets the wall. A seamless resin floor with a coved upstand removes that last weak point, and a dense non-porous film gives you minutes rather than hours before a spill has to be wiped up.
We are deliberately precise about what that means. Our systems show good typical resistance to dilute acids and alkalis, to inorganic salts, to detergents and to alcohols — with the judgement we can actually stand behind stated as: no blistering, no detachment, slight discolouration after seven days' immersion at 25 °C on a seven-day-cured film. That is a splash-and-wipe-down floor. It is not an acid-proof lining, and a floor that has to sit under concentrated reagents overnight is a vinyl-ester or phenolic job, which we do not make.
Discolouration is the honest caveat nobody puts on a brochure. Bleach, strong oxidisers and UV will change the colour of an epoxy film long before they change its bond. A dull patch is cosmetic; a lifted edge is not, and lifted edges are almost always about substrate moisture, a skipped primer or a movement joint that was bridged — which is what our build-up and our site checks are actually designed to control.

Application sequence
Get the actual exposure listWeek −2
Which reagents, which concentrations, how often they spill and how long they sit before someone wipes them. A teaching lab and an organic synthesis lab get different specifications — and sometimes a different product.
Test the slabDay −3
Moisture ≤ 4 % CM and a 24-hour taped polyethylene check near the sink and the external wall. Below-grade or poorly drained labs are where these floors fail.
Strip and grindDay 1, 3–5 h per 100 m²
Old vinyl, adhesive and any failed coating come out completely; then diamond-grind to CSP 2–4 and vacuum to a dust-free surface.
Prime, then form the coveDay 1–2, then 12–16 h
Primer worked into the profile, then the mortar fillet at the wall base and around bench feet. The cove is built before the body so it is one continuous surface.
Pour the bodyDay 2–3, 2–3 h per bay
2–3 mm self-levelling gauge-spread and spiked. One bay or one bench run per shift — no cold joint across a doorway.
Topcoat and release by zoneDay 4, then 7 d
Wear coat with fine aggregate in the wet zones. Walk-on at 24 h, trolleys and heavy use at 72 h, and the full cleaning regime only after 7 days.
Field tips
- Do not let anyone write a chemical list into the specification without a test record behind it. Categories with contact time and a stated verdict are defensible; a concentration matrix nobody measured is a liability.
- Sinks, wash-down bays and floor drains are where a lab floor dies. Put the coarse texture there, detail the cove into the drain frame, and check the fall before you coat.
- Slight discolouration from bleach and oxidisers is normal and cosmetic. Explain it in the handover document, or the first deep-clean becomes a warranty claim.
- A ketone or chlorinated-solvent lab is not an epoxy floor. Say so at quotation stage — vinyl ester and phenolic systems exist for that duty and we do not make them.
- Never bridge a movement joint with rigid resin. In a lab the joint will also be carrying thermal cycling from the slab above.
- Let the floor cure before the fume hood runs. A cold slab under a warm, humid room crosses the dew point and blushes the topcoat — the most common reason a lab floor looks mottled in week one.

Where this system works
QC and analytical suites (HPLC, GC, spectroscopy)
Dust-free seamless surface under benches; solvent spills are wiped, so the specification is built around wipe-up time.
Clinical and pathology sample rooms
Takes a daily disinfectant regime; see the hospital system for the full coved cleanability detail.
Pharmaceutical formulation and weighing rooms
Non-shedding and cleanable; antistatic build available as a separate system where powders or electronics demand it.
University workshops and prep rooms
Oils and cutting fluids with light mechanical duty; fine texture at the sinks.

After handover
- Wipe spills before they dry — the resin tolerates the chemical far better than it tolerates the chemical sitting there.
- Two-bucket clean with neutral or mildly alkaline detergent, then a clean-water rinse. Dried disinfectant residue, not the chemistry, is what dulls a floor.
- Keep bleach to the stated dilution and do not let it stand; if it must, rinse.
- Felt or soft castors under benches and trolleys; grit dragged under a hard castor scratches a semi-gloss film to a dull track.
- Re-coat the wear layer every 4–6 years in a busy lab; the body underneath normally outlives several topcoats.
Frequently asked questions
Which chemicals will it actually resist?
In daily laboratory use: dilute acids and alkalis, inorganic salts, detergents, alcohols, and oil or fuel spillage that gets wiped up. Our stated judgement is no blistering, no detachment and slight discolouration after seven days' immersion at 25 °C on a seven-day-cured film. What we will not do is publish a table of specific reagents at specific concentrations we have not tested — send us your reagent list and we will confirm in writing which ones this floor is specified for.
Can a spill sit overnight?
No, and any floor marketed as if it could is being sold on a misunderstanding. A dense epoxy film gives you minutes to hours of protection so a spill does not reach the slab; that is the real benefit. Concentrated acid or alkali left overnight will mark and can attack the film, and a lab where that happens routinely needs a lining resin, not a coating.
Will it discolour?
Yes, eventually — bleach and other oxidisers, strong solvents and UV will change the colour of an epoxy film long before they affect its bond. Slight discolouration is cosmetic and we state it as the expected result in our own test record. If colour stability matters, we quote a UV-stable topcoat and a mid-tone so marks stay invisible.
What about acetone, dichloromethane or other aggressive solvents?
Epoxy is not the right answer. Ketones and chlorinated solvents will soften, blister and de-gloss it. If your lab uses them routinely at the bench or on the floor, tell us at specification stage — we will say so plainly rather than let you find it after handover.
Do you publish an R-rating or a slip coefficient?
Not without a test. We specify texture by location — fine broadcast at sinks, wash-down and any wet zone, smooth semi-gloss elsewhere — and we will arrange a ramp test on your build if your project documentation requires one. A supplier quoting R11 on a floor they have never tested is guessing.
Can you cove it up the wall and around bench feet?
Yes — a mortar fillet at about 50 mm radius is formed at the wall base before the body coat, so floor and upstand are one continuous material. The same detail is carried around bench feet, pipework and the drain frame, which is where laboratory floors usually start failing.
Do we need an antistatic floor in a lab?
Only if there is a reason — sensitive electronics, flammable vapours or powders. If there is, that is a different build-up with an earthed copper grid, and we specify and measure it as a system on the finished floor. See our cleanroom and electronics system page rather than adding an ESD line to a standard chemical-resistant specification.
Can it go over the existing laboratory vinyl?
Over fully bonded, non-foam-backed vinyl after full removal of any wax or dressing and mechanical abrasion, usually yes. Loose-laid, foam-backed or asbestos-containing floor tile must come out or be surveyed first — a laboratory in an older building is exactly where that matters. See the renovation-over-tiles system for the full conditions.
How long is the lab out of action?
We work bay by bay. Walk-on at 24 hours, benches and trolleys back at 72 hours, and the full cleaning regime from day 7 at 20 °C. The build-up is near-zero-VOC with no solvent flash-off, so the room is usable once the film has set with ventilation running.
