Why buyers specify it
- Specified from a moisture test, not a guess — we tell you before you order whether the slab is sealable
- Moisture-tolerant epoxy primer lets the slab breathe while bonding the system
- Seamless, joint-free field — stops concrete dusting, no grout lines to hold grit
- Satin finish on purpose: hides condensation and stays walkable in summer
- Wipe-clean, tolerant of a damp mop and neutral cleaners
- Walk-on the same day; furniture and rugs back in 24 hours
A below-grade basement floor specified for vapour first and looks second — moisture-tested slab, vapour-tolerant primer, seamless grey finish, walk-on the same day.
Product overview
A below-grade system specified around a moisture reading: 2 mm seamless body at 3.4 kg/m² of system, satin finish, mixed A:B = 3:1 from a 20 kg set (15 kg resin + 5 kg hardener). It carries 80 Shore D, 65 MPa compressive, 9 MPa tensile and 3 MPa adhesion, with a Taber loss of ≤0.03 g (CS-17, 1000 cycles) and a French A+ indoor-emission classification. 30 minutes of pot life, walk-on at about 10 hours, full cure at 7 days.
Specified from the moisture test outward
Below-grade slabs are usually poured without a working vapour barrier, so a basement floor is specified from the moisture test outward rather than from the colour chart. We gate the build-up on a CM reading, an MVER or an in-situ RH value, then use a moisture-tolerant primer and a satin finish that stays walkable when the slab sweats in summer.
An epoxy floor is a wearing surface, not a tanking system — if liquid water comes through, the slab is dealt with first. That distinction is worth reading twice. A vapour-tolerant primer keeps a damp-driven build from lifting; nothing you coat from above stops hydrostatic pressure through a crack, and a floor installed to solve a water problem will fail as a water problem, in the middle of a room, at the worst weather of the year.
Why the reading can stop the job, and why we let it
If the reading does not pass, the answer is not a tougher resin. It is a different build, a longer wait, or no build — and we would rather lose the order than seal a wet slab under a film. A coated basement is less vapour-open than a bare one, so a slab that was tolerable in winter can be a problem in August. Taping a square metre of polyethylene down for a day costs almost nothing, and it is the test most often skipped; a dark patch or beads under the film means the slab is not ready.
A cold basement is a separate schedule question. Cure stalls in a low-teens room, so a January job is planned in days rather than hours, and the walk-on figure above is a warm-room figure.
Where it is the right pick
- Home gym and training area — seamless, dust-free, and tolerant of a damp mop.
- Recreation and media room, where a satin film hides condensation that a gloss sheet would advertise.
- Storage and utility room, shelving and pallet jacks on soft wheels.
- Laundry and plant room, where spills and a wet floor are the normal condition.
Level is a different problem from damp
If the slab is badly out of level, a cementitious underlayment is the usual way to get there first. It stays a preparation layer here, though: the resin only goes on once the reading has come down, and the skim has to be ground and primed rather than buried under a closed film. Send the moisture reading if you have one, the age of the slab, whether there was ever a damp-proof membrane, and what the room is used for — those four decide the build.
Basements fail for one reason that garages do not: the slab is below grade, usually poured without a working vapour barrier, and it is woken up by a coating only when the moisture behind it has somewhere to go. Hydrostatic vapour pressure builds under a sealed film, and the first you hear about it is blistering or peeling along the perimeter. That is why we specify a basement floor from the moisture test outward, not from the colour chart.
So the build-up differs from our garage system in three places. The primer is a moisture-tolerant epoxy (or a water-based epoxy) that lets the slab breathe while it wets the surface. The finish is a satin rather than a mirror gloss, because a below-grade slab sits below the dew point in summer and sweats — a high-gloss film turns that condensation into a slip hazard. And we do not claim to stop water: an epoxy floor is a wearing surface, not a tanking system. If liquid water comes through, the slab has to be dealt with first.
What you do get is the part that matters day to day: a seamless, dust-free floor with no joints to trap grit, wipe-clean, tolerant of a damp mop, and available in a neutral grey that reads well under warm basement lighting rather than the cold institutional look of a hospital floor.

Application sequence
Test the slab before anything elseDay −3
CM reading or a 24-hour taped polyethylene square in three positions, one near the perimeter. If the slab fails, we stop and talk about a breathable water-based system or dehumidification — not about colour.
Diamond-grind and vacuumDay 1, 3–4 h
16–24 grit diamond segments open the pores and remove laitance and any old sealer. Acid etching is not acceptable below grade — it leaves salts in the slab.
Fill cracks and jointsDay 1, 1–2 h
Cracks to 3 mm are overfilled with thixotropic epoxy; movement joints stay movement joints and are covered with a flexible detail, never bridged.
Roll the moisture-tolerant primerDay 1, then 12–16 h
Wet edge to wet edge, 0.25–0.4 kg/m². This is the coat that decides the life of a basement floor, so it is never skipped to save a day.
Pour the self-levelling bodyDay 2, 2–3 h
3.4 kg/m² mixed, gauge with a notched squeegee, back-roll and spike-shoe to release air. Basements are cold, so open time is longer and the pour must not be rushed.
Satin topcoat and cureDay 3, then 7 d
A low-sheen coat at 0.15–0.2 kg/m² for slip behaviour when damp. Walk-on the same evening; nothing sits on the floor for 24 hours, and full chemical resistance takes 7 days.
Field tips
- Never coat a slab that has failed a moisture test because the customer is in a hurry — that is where the peeling videos come from.
- Check for a perimeter drain or a sump that runs: a dehumidifier cycling hard is a sign the slab will keep pushing vapour.
- Do not bridge a movement joint with rigid epoxy. It will re-open as a crack in the film within a season.
- Cold basements cure slowly. At 10 °C, expect roughly double the walk-on time and do not close the room with a space heater blowing on the wet film.
- Skip the mirror-gloss topcoat. Below grade it shows every bit of condensation and reads slippery under furniture.
- Let new concrete outgas first: a slab poured less than 28 days ago will blister regardless of primer choice.

Where this system works
Recreation and media room
No joints to trap grit underfoot, and a neutral grey that keeps its tone under warm 3000 K lighting instead of going blue.
Storage and utility room
Stops concrete dusting on boxes and shelving; spills from a water heater or freezer mop up without staining.
Laundry and plant room
Seamless upstands at the wall base, so a leak reaches the drain rather than soaking into a joint.
Wine cellar and utility basement
Sealed surface that tolerates periodic damp mopping; we keep the build-up breathable so the walls can still dry inward.

After handover
- First 7 days: no rugs, no appliance feet, no dragging of shelving — the film is hard but not yet chemical-resistant.
- Sweep or vacuum, then damp mop with neutral cleaner. Abrasive pads will dull the satin sheen in patches.
- Keep a dehumidifier or the HVAC running through the first summer after installation; a newly sealed slab needs somewhere for its residual moisture to go.
- Re-coat the satin topcoat every 4–6 years in a used basement; the body underneath normally never needs touching.
- If a damp patch appears at the perimeter, find the water before you patch the floor — a coating repair on an active leak will fail again.
Frequently asked questions
Can I put epoxy on a damp basement floor?
Not on a slab that is actively wet, and not without a test. We ask for a CM reading (≤ 4 %), an MVER (≤ 4 lb / 1000 ft² / 24 h) or in-situ RH (≤ 75 %), or a 24-hour taped polyethylene check in three spots. Inside those limits we use a moisture-tolerant primer and a breathable build-up. Outside them the answer is dehumidification or a vapour-permeable water-based system, not a standard epoxy film.
Will epoxy waterproof my basement floor?
No, and anyone selling it as a waterproofing layer is overselling. Epoxy seals the surface against dust and spills; it does not stop hydrostatic pressure. Water that comes up through cracks or the perimeter will find its way under the film and lift it. Fix the water, then coat.
Why satin and not high gloss in a basement?
A below-grade slab usually sits below the summer dew point, so it sweats. Under a mirror-gloss film that condensation looks like a wet floor and feels slippery. A satin or fine-textured finish hides it and keeps real grip; it also hides roller marks and the small scuffs that a storage room collects.
How long before I can put a gym or furniture back?
Walk-on in 8–12 hours at 20 °C. Light furniture and equipment in 24 hours. Rugs, rubber mats and appliance feet only after 7 days, because the film needs full cure before something sits on it and traps moisture against the surface.
Is it safe to sleep or train in a basement after installation?
Our floors are near-zero-VOC, two-component systems with no solvent to flash off. Ventilate during application and for 24 hours after; the room is normally usable the next day. If the basement has no mechanical ventilation, we schedule the job so the doors stay open overnight.
What about radon below the slab?
A coating is not a radon mitigation system and we do not sell it as one. Dense epoxy films do reduce surface exhalation, but the only reliable answer to a high radon reading is sub-slab depressurisation. If you have not tested, test before you enclose the room.
Can you do it over old paint or a previous epoxy floor?
Over old epoxy or a cured film, no — it has to be mechanically removed by grinding, or the new layer bonds to the weak one. Over water-based basement paint, sometimes: full removal is the specification, and we will tell you honestly whether the job is a strip or a re-slab conversation.
How much does a basement system cost per square metre?
Material for a 2 mm self-levelling build-up with moisture-tolerant primer and satin topcoat is typically 3.6–4.0 kg/m², so a 40 m² basement takes about 6–7 sets. Send us the slab age, the moisture reading and your country and we will quote the exact build-up rather than a range.
