Dew Point
Beware of condensation
The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product.
Substrate Temperature
+10 °C min. / +30 °C max.
Substrate Moisture Content
≤ 4 % parts by weight
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).
Waiting Time / Overcoating
Before applying Sikafloor®-2640 on Sikafloor®-150/-151 allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 hours | 3 days |
| +20 °C | 12 hours | 2 days |
| +30 °C | 8 hours | 1 day |
Before applying Sikafloor®-2640 on Sikafloor®-2640 allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 12 hours | 3 days |
| +20 °C | 6 hours | 2 days |
| +30 °C | 3 hours | 1 day |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
