Rayson UraForce · Polyurethane finishes
Rayson UraForce WB52 is a two-component, water-based aliphatic urethane floor topcoat — low-VOC, low-odour and UV-resistant — that can be combined with broadcast aggregate for an anti-slip finish.
UraForce WB52 is the finish coat of the Rayson water-based floor system. The two-component aliphatic urethane cures to a high-strength film with excellent abrasion resistance, low dirt pick-up, pencil hardness above H and gloss of 85 at 60° in the gloss grade — while staying low-VOC and low-odour for occupied buildings.

| Surface preparation | New concrete at least 28 days old, moisture below 5%; remove laitance and loose material; mechanically prepare damaged concrete to exposed aggregate. On existing concrete, prefer mechanical preparation and industrial vacuuming; wash oil and grease with industrial detergent; substrate sufficiently dry at surface relative humidity of 75% or lower. |
|---|---|
| Mixing / dilution | Two pre-weighed parts, mix ratio as shown on the supplied set size (4:1 or 9:1 A:B by weight); stir parts separately, combine and mix with a slow-speed drill and paddle until uniform; pot life 6 hours at 25 °C |
| Application method | Short-bristled brush, Roller |
| Coverage | Available from the Rayson technical team on request. |
| Application conditions | Minimum substrate temperature 5 °C; minimum mixing temperature 10 °C; minimum curing temperature 5 °C; keep floor dew point within 3 °C of atmospheric temperature. |
| Drying & curing | Surface dry 2 hours at 28 °C; trafficable after 3 hours |
| Recoat interval | Available from the Rayson technical team on request. |
| Film / thickness | Available from the Rayson technical team on request. |
