Why specify Rayson UraForce SB72

Rayson UraForce SB72 has one clearly defined, verifiable job in the coating system.

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. Best for exterior industrial floors and any coated floor where colour and gloss must survive sunlight.

01

Retains colour and high gloss under strong UV

Exterior industrial floors

02

Excellent abrasion resistance (90 mg, CS-17 Taber)

Floors requiring long-term colour and gloss retention

03

Documented resistance to a wide schedule of acids, alkalis and fuels

Chemically exposed floors needing an easy-to-clean coloured finish

Representative application environment for Rayson UraForce SB72
Exterior performance

Keep the colour. Keep the gloss.

A UV-stable polyurethane finish that protects exterior industrial floors against sunlight, abrasion and chemical exposure.

From substrate to service

A controlled route to applying Rayson UraForce SB72.

This sequence supports early planning. It does not replace the current Technical Data Sheet, approved method statement or project-specific technical review.

  1. 01

    Inspect and prepare the substrate

    Primed concrete (minimum 28 days cure, moisture content below 4%, laitance-free)

  2. 02

    Prepare the material as specified

    Mix ratio 3:1 (A:B) by weight; add all of Part B to the Part A container and mix with an electric mixer until homogeneous; do not dilute with thinner; pot life 8 hours at 25 °C

  3. 03

    Apply with the correct tools

    Recommended methods: Fine smooth lamb wool roller. Confirm coat count and thickness for the project.

  4. 04

    Protect through the required cure

    Foot traffic 8 h at 25 °C; vehicular traffic 48 h; full chemical resistance 7 days. Recoat window 8–48 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 SB72 serves as the finish. Confirm the complete build-up against the substrate, exposure and project requirements.

Suitability check

Confirm the substrate and real service environment before specifying.

02

Choose something else when

  • Do not dilute with thinner
  • In cold weather, allow a longer cure before applying the second coat
  • Solvent-based — provide adequate ventilation; not for occupied areas without ventilation control
  • Requires a fully cured, efficiently sealing primer coat — surface defects telegraph through thin finishes
  • Occupied or unventilated areas during application — solvent-based
  • Unprimed or poorly sealed concrete
  • Thick-build or self-levelling duties — this is a thin-film finish
  • Immersion service or chemical exposures outside the tested schedule without technical confirmation

Substrate requirements
  • Primed concrete (minimum 28 days cure, moisture content below 4%, laitance-free)
  • The primer coat must be fully cured and must seal the concrete efficiently before finishing

Common technical questions

What to know before specifying Rayson UraForce SB72.

Will UraForce SB72 yellow outdoors?

No — the aliphatic polyurethane chemistry is specifically chosen for colour and gloss retention under strong UV. That is its core advantage over epoxy finishes.

Which chemicals has it been tested against?

The source resistance schedule covers citric, tartaric, acetic, lactic and phosphoric acids, nitric acid 25%, hydrochloric acid 10%, sulphuric acid 30%, sodium hydroxide 30%, petrol, sugar solution and formaldehyde 38%. For any exposure outside that schedule, or unusual concentration and temperature, confirm with our technical team.

How long between the two coats?

Apply the second coat within roughly 8–48 hours at 25 °C; cold weather stretches the required cure before recoating.

When can vehicles drive on it?

Indicatively 48 hours at 25 °C, with full chemical resistance developing over 7 days. Programme heavy or chemical service accordingly.

Can it be applied without a primer?

No. Efficient sealing of the concrete by a cured primer coat is essential — an unsealed slab causes bubbles and defects in the thin finish film.

Is it suitable for occupied buildings?

Only with proper ventilation — it is solvent-based. For odour-sensitive interiors choose the water-based UraForce WB52, WB58 or WB60.
