Rayson LevelShield SL120

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.

Best for

Best for production areas, warehouses, loading bays and clean environments that need a seamless, hard-wearing, self-levelled epoxy floor.

Overview

LevelShield SL120 flows out under trowel, notched rake or roller into a seamless, self-smoothed wearing surface — the standard answer where roller-applied coatings are not enough and a level, joint-free floor is required. Solids content is 100% in both parts, so what goes down is what cures.

The cured floor combines medium to heavy chemical resistance with high mechanical strength: compressive strength up to 50 N/mm², Shore D hardness up to 70 and abrasion loss as low as 45 mg in standard Taber testing. That profile suits pharmaceutical facilities, clean rooms, assembly halls, plant rooms, garages, maintenance workshops and storage areas.

Being solvent-free, SL120 can be installed in enclosed and poorly ventilated spaces, and cure progresses predictably: foot traffic in 18–24 hours, light traffic in 2–4 days and full cure within about a week depending on temperature.

Recommended uses

  • Areas requiring resistance to mechanical loading and abrasion
  • Pharmaceutical facilities and clean rooms
  • Warehouses, storage areas and loading bays
  • Assembly halls, plant rooms and garages
  • Production areas and maintenance workshops

Suitable substrates

  • Mechanically prepared concrete (minimum 28 days old, moisture content below 5%)
  • Substrate pull-off strength above 1.5 N/mm² after preparation

Key benefits

  • 100% solids, solvent-free — install in enclosed areas without solvent odour
  • Self-smoothing application gives a seamless, level wearing surface
  • Medium to heavy chemical resistance with high compressive and abrasion performance
  • Durable, easy-to-clean finish with excellent impact resistance

System position: Body coat

A body coat builds the main thickness and mechanical performance of the floor, applied over a primer and usually sealed with a finish.

Application method

  • Steel trowel
  • Notched rake
  • Squeegee and roller
  • Spike roller to de-aerate

Technical information

The figures below are a guide for planning. Site conditions and workmanship affect results — confirm the details for your project with our technical team.

Coverage Approximately 1.6–2.0 kg/m² as a self-smoothing wearing coat, subject to filling grade, porosity, level variation and wastage
Mixing Two pre-weighed parts, mix ratio 4:1 (A:B) by weight; mix mechanically for at least 2–3 minutes; pot life up to 20 minutes at 28 °C
Drying & curing At +20 °C: foot traffic 24 h, light traffic 4 days, full cure 7 days. At +30 °C: foot traffic 18 h, light traffic 2 days, full cure 5 days. Recoat window 24 h–2 days at +20 °C (16 h–1 day at +30 °C)
Pack sizes Part A 16 kg / Part B 4 kg per set

Limitations

  • Minimum substrate temperature 5 °C; curing between +10 °C and +35 °C; concrete moisture content maximum 5%
  • Short pot life (about 20 minutes at 28 °C) demands organised batching and placement
  • Cure and overcoat times are approximate and shift with ambient and substrate conditions
  • Epoxy chemistry — not colour-stable under exterior UV exposure

Not suitable for

  • Exterior UV-exposed decks without a UV-stable topcoat
  • Substrates with moisture above 5% or rising damp
  • Severe thermal-shock zones such as hot wash-down areas — use Rayson PurScreed PC70
  • Sloped surfaces where a self-smoothing product cannot hold grade

Recommended systems

Self-levelling production floor

  1. Mechanically prepare the slab and repair defects with Rayson PatchBond TX80
  2. Prime with Rayson PrimeBond E20
  3. Apply Rayson LevelShield SL120 self-smoothing wearing coat and spike-roll to de-aerate

Frequently asked questions

How thick is a LevelShield SL120 floor?

It is applied as a self-smoothing wearing coat at a consumption of roughly 1.6–2.0 kg/m²; the achieved thickness depends on filling grade and levelness of the slab. Confirm the build-up for your traffic with our technical team.

When can the floor take traffic?

Indicatively, foot traffic within about a day, light traffic in 2–4 days and full cure in 5–7 days depending on temperature — faster in warm conditions.

Does it need a primer?

Yes. Apply over a suitable Rayson epoxy primer such as PrimeBond E20 on mechanically prepared concrete to guarantee adhesion and avoid pinholes from substrate porosity.

How chemical-resistant is it?

The system is rated for medium to heavy chemical resistance. For a specific chemical exposure — substance, concentration, temperature and contact time — always verify against the resistance schedule with our technical team.

Why does the pot life matter so much?

Mixed material stays workable for only around 20 minutes at 28 °C and cures faster in bulk. Batching, placement and spike-rolling need to run as a continuous, well-crewed operation.

Is it suitable for clean rooms?

Yes — the seamless, easy-to-clean surface and solvent-free installation suit pharmaceutical facilities and clean rooms.
