Rayson UraForce SB72
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.
Concrete TDS RY-TDS-701
Best for
Best for exterior industrial floors and any coated floor where colour and gloss must survive sunlight.
UraForce SB72 pairs a pigmented polyester polyol base with an aliphatic polyisocyanate hardener — the chemistry that keeps polyurethane finishes bright outdoors. Where epoxies chalk and yellow, SB72 retains colour and high gloss under strong ultraviolet exposure.
The finish is a genuine performer as well as a good-looking one: abrasion loss of 90 mg in standard CS-17 Taber testing, and documented resistance to spillages including 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%. The result is a hygienic, easy-to-clean floor that protects and dustproofs the concrete beneath.
It is applied by fine lamb wool roller over a cured primer coat in two thin finish coats. As a solvent-based product it needs ventilation during application — plan occupied-area work accordingly, or look at the water-based UraForce WB range.

Typical systems
Limitations
- 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
Not suitable for
- 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

Quoted after inspection The practical details
Rayson UraForce SB72: questions people ask
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.
