Self-levelling epoxy flows into a seamless, self-smoothed wearing surface — the standard answer for Singapore production floors, warehouses and clean environments with daily forklift traffic. Rayson LevelShield SL120 delivers high mechanical strength and medium-to-heavy chemical resistance over PrimeBond E20 damp-tolerant primer, with a conductive variant (StaticGuard CX90) for ESD areas. Manufactured in Singapore, specification published in an open TDS.

Prime with PrimeBond E20 — a solvent-free epoxy bonding primer that anchors to dry or damp concrete (PrimeBond E20 TDS (PDF)), which matters on Singapore ground-bearing slabs. Body coat with LevelShield SL120 solvent-free self-smoothing epoxy (LevelShield SL120 TDS (PDF)). For ESD-protected areas, substitute the wearing surface with StaticGuard CX90 conductive self-smoothing epoxy (StaticGuard CX90 TDS (PDF)). Sunlit zones take a UraForce SB72 UV-stable polyurethane finish so colour holds (UraForce SB72 TDS (PDF)).
Diamond grinding or shot blasting to expose sound concrete, repair of spalls and joints with MortarBond EM90, moisture assessment, then priming. Self-levelling systems are less forgiving of skipped preparation than roller coats — the flatter finish shows every shortcut. Full sequence in the surface preparation guide.
LevelShield SL120 is manufactured by Rayson in Singapore and its complete specification — build, coverage, cure windows, chemical duty — is published in the open TDS library. Compare it line by line against any alternative quote, then talk to the team that makes it.

Self-smoothing · solvent-free
Rayson LevelShield SL120 is a solvent-free, two-component, self-smoothing epoxy floor system that delivers a seamless wearing surface with medium to heavy chemical resistance and high mechanical strength.
Solvent-free · damp tolerant
Rayson PrimeBond E20 is a two-component, medium-viscosity, solvent-free epoxy bonding primer that anchors resin floor systems to concrete, screed, asphalt and prepared metal — on dry or damp substrates.
Conductive ESD flooring
Rayson StaticGuard CX90 is a two-component, solvent-free conductive epoxy flooring that gives ESD-protected areas a self-smoothing, permanently conductive, chemically resistant wearing surface.
UV-stable polyurethane finish
Rayson UraForce SB72 is a two-component, solvent-based polyurethane floor finish that holds its colour and high gloss under strong UV while resisting abrasion and a broad range of chemicals.

Open the librarySelf-levelling (self-smoothing) epoxy flows out into a thicker seamless layer instead of a thin painted film. It is worth it when floors carry daily forklift traffic, need a dead-flat cleanable surface, or must hide a worn substrate profile. Light-duty stores rarely need it — a roller coat like FloorGuard R50 does that job for less.
The system self-smooths within its layer, but it will not fix a slab that is out of level — high spots are ground and hollows pre-filled during preparation. "Self-levelling" describes the finish texture, not a substitute for substrate correction.
Yes — the seamless, joint-free surface is exactly what clean production wants, and it is a standard choice for clean environments. Where static control is also required, the conductive equivalent is Rayson StaticGuard CX90, a self-smoothing conductive epoxy for ESD-protected areas.
Epoxy yellows under UV, so sunlit zones take a UV-stable aliphatic polyurethane finish — UraForce SB72 — over the epoxy body coat, or a different system entirely outdoors. Indoors away from direct sun, epoxy keeps its colour.
Thicker than a roller film, thinner than a screed — the specific build and coverage for LevelShield SL120 is published in its technical data sheet. As a rule the build is chosen from traffic: heavier wheels, more build.
