System Structure
Sikafloor® MultiDur WB-28
| Product | Layer | |
| 1. | Primer | Sikafloor®-2510 W + 10 % water by weight |
| 2. | Wearing Layer | Sikafloor®-2510 W filled 1 : 1 with quartz sand (0.1 – 0.3 mm) Broadcast in excess with natural or coloured quartz sand |
| 3. | Top Coat | Sikafloor®-2510 W |
For a more decorative finish use coloured quartz to broadcast the wearing layer and transparent Sikafloor®-2510 W as a top coat.

Waiting Time / Overcoating
Before applying Sikafloor®-2510 W on Sikafloor®-2510 W, allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 48 hours | 7 days |
| +20 °C | 20 hours | 6 days |
| +30 °C | 10 hours | 3 days |
If relative air humidity is ≥ 75 %, the waiting time is increased by at least 24 hours.
Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.
Applied Product Ready for Use
| Temperature | Foot Traffic | Light Traffic | Full Cure |
| +10 °C | 48 hours | 5 days | 10 days |
| +20 °C | 20 hours | 3 days | 7 days |
| +30 °C | 10 hours | 2 days | 5 days |
Note: Times apply when the last layer of the system has been applied. Times are affected by changing ambient conditions, particularly temperature and relative humidity.
Consumption
| Layer | Product | Consumption |
| Primer | 1 × Sikafloor®-2510 W + 10 % by weight water | 0.15 – 0.2 kg/m² |
| Wearing Layer | Sikafloor®-2510 W filled 1 : 1 with quartz sand 0.1 – 0.3 mm Broadcast in excess with natural or coloured quartz sand | 3.8 kg/m² ~4 – 6 kg/m² |
| Top Coat | Sikafloor®-2510 W split into two application steps | 0.7 – 0.9 kg/m² for both steps |
Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
