Application
Ambient Air Temperature
Maximum | +30 °C |
Minimum | +10 °C |
Relative Air Humidity
Maximum | 75 % r.h. |
Dew Point
Refer to the individual Product Data Sheet.
Substrate Temperature
| Maximum | +30 °C |
| Minimum | +10 °C |
Substrate Moisture Content
| Substrate | Test method | Moisture content |
| Cementitious substrates | Sika®-Tramex meter, CM - measurement or Oven-dry-method. | ≤ 6 % |
No rising moisture (ASTM D4263, polyethylene sheet)
Osmosis caused by rising moisture or incorrect primer application is not covered by the product warranty.
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 | 5 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 % wt water | 0.15–0.2 kg/m² |
| Wearing layer | Sikafloor®-2510 W filled 1 : 1 with quartz sand 0.1–0.3 mm or Sika® Aggregate-508 | 3.8 kg/m² |
| Broadcast in excess | Quartz sand 0.3–0.8 mm Sika® Aggregate-501 | 4–6 kg/m² |
| Top coat | Sikafloor®-2510 W | Two coats at 0.35–0.45 kg/m² |
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 product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
