Excellent abrasion resistance and low dirt pick-up
Topcoat finishes on hard surfaces such as stone and limestone
Good water repellence with pencil hardness above H
Hygienic coatings for walls and floors
Durable colour without the heavy odour.
A water-based aliphatic polyurethane finish for schools, offices and retail spaces that need UV and abrasion resistance.
A controlled route to applying Rayson UraForce WB58.
This sequence supports early planning. It does not replace the current Technical Data Sheet, approved method statement or project-specific technical review.
- 01
Inspect and prepare the substrate
Mechanically prepared concrete (minimum 28 days old, moisture content below 5%)
- 02
Prepare the material as specified
Two pre-weighed parts, mix ratio 9:1 by weight; stir parts separately, combine and mix with a slow-speed drill and paddle for 1–2 minutes; pot life 1–2 hours
- 03
Apply with the correct tools
Recommended methods: Short-bristled brush, Roller. Confirm coat count and thickness for the project.
- 04
Protect through the required cure
Surface dry 6 hours at 25 °C
Coating system cutaway
Every layer has a job—from prepared substrate to service surface.
This diagram explains a typical system position, not a fixed specification. Primer, body coat, finish, thickness and detailing must be confirmed for the project.
Position in the system Finish
Rayson UraForce WB58 serves as the finish. Confirm the complete build-up against the substrate, exposure and project requirements.

Relevant applications
Relevant industries
Choose something else when
- Minimum substrate temperature 5 °C; minimum mixing temperature 10 °C; minimum curing temperature 5 °C
- Mixed material must be used within its 1–2 hour pot life; cures faster in hot weather and in large batches
- Hardener shelf life is shorter than the base and moisture-sensitive — store sealed and dry
- Thin-film topcoat — requires a sound, sealed substrate or system beneath
- Heavy industrial traffic without a suitable body coat beneath
- Immersion or chemical containment service
- Filling or levelling defective substrates — it is a thin decorative-protective film

What to know before specifying Rayson UraForce WB58.
Why choose WB58 over a solvent-based PU?
Water-based application: it can go into occupied and enclosed spaces without solvent odour, while keeping the abrasion resistance and UV performance of aliphatic PU chemistry.
What colours are available?
It is supplied pigmented, with grey among the colours offered. Confirm the current colour range with our sales team.
How many coats does a floor need?
A minimum of two coats by brush or roller, stripe-coating edges first.
What is the coverage rate?
Confirm coverage with our technical team when planning quantities.
How should the hardener be stored?
Sealed, dry and under cover — the PUR hardener is moisture-sensitive and has a shorter shelf life than the base component.
