A controlled route to applying Rayson UraForce SB65.
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 4:1 by volume; stir parts separately, combine and mix with a slow-speed drill and paddle for 1–2 minutes; pot life approximately 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 SB65 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 pot life; cures faster in hot weather and in large batches
- Solvent-based — provide adequate ventilation; not for occupied areas without ventilation control
- Thin-film clear coat — substrate defects and colour show through
- Occupied or unventilated areas during application — solvent-based
- Hiding substrate defects or colour — it is a clear coat
- Heavy-duty build-ups — it is a thin protective film, not a wearing screed

What to know before specifying Rayson UraForce SB65.
Is UraForce SB65 really non-yellowing?
Yes — it uses aliphatic polyurethane chemistry, the class of PU specifically formulated not to yellow under UV, with outstanding weather durability.
What sheen options are there?
Clear gloss, satin and matt. The gloss grade measures around 85 at 60°.
Can it be used on walls?
Yes. It serves as a hygienic, washable clear finish on walls as well as floors, over suitably prepared substrates.
How many coats are needed?
A minimum of two coats, stripe-coating edges with a brush before rolling the field.
What is the coverage per litre?
Ask our technical team for current coverage guidance before ordering.
Solvent-based or water-based — which clear coat should I pick?
SB65 for maximum weather durability where ventilation is available; UraForce WB60 where low odour and occupied-building working are the priority.
