Flake Epoxy Colored Sand Flooring

Product overview

Decorative flakes and coloured quartz broadcast into a wet epoxy coat and locked under a clear topcoat: a 4 mm build at 4 kg/m² that is rugged, slip-resistant and genuinely forgiving of the slab underneath it. The system bonds at 3.8 MPa, cures to >85 Shore D with 75 MPa compressive, and keeps a Taber loss of ≤0.02 g — the same figure our garage broadcast carries. Walk-on at about 10 hours, light service from 24 hours, full cure at 7 days.

Why a 4 mm broadcast forgives a bad slab

Thickness is what buys tolerance. A 2 mm film follows whatever it is poured onto; a 4 mm broadcast bridges hairline cracks, buries an old tile joint and levels a slab that was never going to be flat, because the aggregate is carrying the profile rather than the resin. That is also why this is the floor we put on a garage or a workshop floor with history: it hides the history without pretending the slab is new.

The grip comes from the same place. The broadcast leaves an open mechanical profile, so water and ice film on the surface rather than building a sheet under a tyre or a shoe — and because the texture is the aggregate itself rather than a dusting of loose grit, it does not polish away in the first year.

What you actually specify

Four blends plus a multi-colour: Grey Blend, Tan Blend, Charcoal Blend, Blue Blend and Multi-Colour, in a matte finish. Matte is the practical choice where a floor sees daily use — a semi-gloss or gloss sheet shows every footprint and every squeegee swirl, a matte broadcast does not. Supplied as a 25 kg set at A:B = 2:1.

The working window is 25 minutes, which is short by design: the broadcast has to land while the resin is still wet enough to grab it. On anything larger than a single bay that is a two-person job working in bays, not a roller-and-done afternoon.

What it will not do

It is a texture. If the brief is a glass-flat, mirror-smooth sheet, that is a different build — see epoxy self-levelling. And the broadcast only stays clean while the topcoat stays intact: an unsealed profile is where dirt lives, so the wear layer is a maintenance item, not a decoration. Specify the topcoat at the same time, not after it has worn.

Numbers we publish

Compressive 75 MPa, hardness >85 Shore D, adhesion 3.8 MPa, abrasion ≤0.02 g (Taber CS-17, 1000 cycles), VOC 8 g/L, warranty 10 years. These are typical laboratory values for the system, not a guarantee for your slab: substrate, climate and workmanship move the outcome, so the final specification is confirmed in writing before you order.

Typical applications

Garages, workshops, warehouses, factory floors, kitchens and wet areas, and any industrial floor over a substrate with history.

Terrazzo-look, and what it is not

When a buyer asks this range for a terrazzo floor, what they are usually pointing at is a field of multi-colour chip set in a resin matrix — which is exactly what the Multi-Colour blend of this broadcast build gives you, at 4 mm and 4 kg/m². The chips carry the colour, the topcoat carries the wear, and the pattern breaks up footprints and dust the way a plain grey sheet never does. It is the reason this build gets specified for a workshop that is also the room people walk through.

The honest boundary is the surface plane. True epoxy terrazzo is poured with aggregate exposed at the surface, then ground and polished back down to a flat, exposed-stone film. That is a different assembly with different equipment, and we do not supply it — if the specification calls for polished terrazzo with aggregate exposed by grinding, it is a different supplier, and finding that out at handover is the expensive version of the same conversation.

What this build does instead is lock the aggregate under the wear coat. The profile stays open, so the floor keeps its texture under damp feet rather than turning it into a polished sheet, and the Taber loss stays at ≤0.02 g (CS-17, 1000 cycles) on a >85 Shore D, 75 MPa section bonded at 3.8 MPa. The trade is explicit: you get a terrazzo-look field and a floor that forgives a bad slab, and you do not get a mirror. Specify Matte and keep the topcoat maintained, and the pattern keeps reading as a decorative floor rather than as a scuffed one — this system carries a 10 year warranty at 8 g/L VOC.

If the brief really is a seamless, glass-flat decorative sheet rather than a chip field, look at our metallic coloured sand build, which gets its depth from a clear binder over sand instead of from broadcast chip.
