Substrate temperature | Minimum | Maximum |
+10 °C | 24 hours | 4 days |
+20 °C | 12 hours | 2 days |
| +30 °C | 8 hours | 1 days |
Before applying Sikafloor®-381 ECF on Sikafloor®-220 W Conductive allow:
Substrate temperature | Minimum | Maximum |
+10 °C | 26 hours | 7 days |
+20 °C | 17 hours | 5 days |
| +30 °C | 12 hours | 4 days |
Before applying Sikafloor®-381 on Sikafloor®-381 ECF broadcast with conductive aggregate allow:
Substrate temperature | Minimum | Maximum |
