A crack-bridging, UV-stable self-levelling topcoat for sunlit rooms and floors with radiant heating.
Product overview
A flexible, UV-stable self-levelling topcoat: 1.8 kg/m² per mm of build, poured at 3 mm, semi-gloss, mixed A:B = 3:1 out of a 20 kg set. That is about 5.4 kg/m² of material on a full 3 mm pour. It holds >75 Shore D with 60 MPa compressive and 42 MPa tensile, bonds at 3.2 MPa, wears at ≤0.03 g on the Taber plate, and measures 4 g/L VOC. Working windows: 35 minutes of pot life at 20 °C, walk-on at about 8 hours, light service from 24 hours, full cure at 7 days.
The trade this build makes
Read the hardness against our standard self-leveling epoxy and the difference is deliberate: that one is >80 Shore D at 80 MPa compressive, this one is >75 Shore D at 60 MPa. A film that gives a little is a film that can be stretched over a moving substrate instead of splitting when the substrate moves. Where a rigid 2 mm sheet locked straight to a slab is the build that shows hairline lines tracking along the heating runs, a crack-bridging coat is the one that keeps the surface continuous.
What we do not do is publish a cycle count for it. The softness is a real, measured property of the cured film; how many thermal cycles a particular slab will put on it depends on the slab, so the honest version of this claim is the mechanism plus the duty, not a number.
Where it is the right pick
Three situations, all of which are in the same building most of the time:
- Over radiant heating. The features list carries radiant-heat-compatible because the film is expected to be warm most of the year and to change size twice a day. Switch the circuit down before the crew arrives and ramp it back slowly rather than going straight to set temperature.
- In strong daylight. The topcoat is a UV-stable formulation, which means it resists the ambering a standard bisphenol epoxy shows under glazing light. It does not mean the colour is frozen; on a sunroom floor, a clear or warm-white build is the safer specification.
- Over sound existing tile. Tile is a listed substrate here precisely because a crack-bridging film at 3 mm spans the joints instead of copying them, which is what a thin build tends to do.
Where it is the wrong pick
This is a comfort-and-light specification, not a duty specification. It carries no chemical-resistance claim, so a laboratory or wash-down bay belongs on one of our chemical-resistant builds. It is 3 mm and 60 MPa, so pallet traffic and forklift wheels are not its job. And it is an interior film: a balcony that sees weather needs a different topcoat conversation than a sunroom that sees glass.
What we need to quote it back correctly
Send the room size, the slab age and whether there is heating under it and at what temperature; the existing floor if there is one; and how much sun the room actually gets. From that we confirm the build, the colour and the set count — a 20 kg set covers a predictable area at 3 mm, and guessing the area is how projects end up short one set on day two.
Self-levelling epoxy is poured, not trowelled: the mixed two-component resin finds its own level, so the surface follows the beam line rather than the applicator's wrist. The result is a glass-smooth, joint-free floor with no texture to trap dust.
Because the material is self-de-airing only to a limit, the spiked-roller pass is not optional — it releases entrapped air and evens the film against the substrate's pinholes.

Application sequence
Assess and grindDay 1
Measure flatness and moisture, then diamond-grind to CSP 1–2 and vacuum the dust.
Repair and level4 h + dry
Fill cracks, bridge joints, and pre-level deep low spots with the cementitious compound.
Prime2–3 h
Roll the low-viscosity primer; a starved primer causes pinholes.
Mix and pour in ribbons30 min/batch
Weigh A:B exactly, mix 2–3 min slowly, pour and guide with a gauge rake.
De-air with a spiked rollerContinuous
Roll immediately and again after 10 minutes; keep the wet edge broken.
Cure, protect, releaseNext day
Keep dust and moisture off for 24 hours; do not seal before full outgassing.
Field tips
- Temperature is the hidden variable: cold slabs increase viscosity and leave rake marks.
- Change the mix crew's water-free discipline — never thin epoxy self-levelling with solvent.
- Plan the escape route before the first bucket; you cannot walk back over a live pour.
- For cleanrooms, tape the perimeter detail and coving separately — the fillet radius is where audits look.

After handover
- Damp mop with neutral or mildly alkaline cleaner; the flat surface releases dirt easily.
- Use wheel-compatible castors; metal shavings drag visible lines on gloss finishes.
- Apply a maintenance coat in high-traffic aisles once the gloss bands appear.
Frequently asked questions
How much movement can the film bridge?
Up to about 0.3 mm of static hairline cracking. Active structural joints still have to move freely — we detail them, not cover them.
Is it really safe under sunlight?
The topcoat is an aliphatic, UV-resistant formulation, so it does not amber the way standard bisphenol epoxy exposed to UV does.
What surface temperature is allowed with radiant heating?
Keep the working surface below 60 °C and ramp the heating up and down slowly; switch it off 24 h before application.
