Application
Product Temperature
Please refer to the individual Product Data Sheets
Ambient Air Temperature
+10 °C min. / +30 °C max.
Relative Air Humidity
80 % r.h. max.
Dew Point
Beware of condensation!
The substrate and uncured floor must be at least 3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.
Substrate Temperature
+10 °C min. / +30 °C max.
Substrate Moisture Content
When performing application work with Sikafloor® MultiDur ET-31 V, the substrate moisture content must not exceed 4 % pbw measured by Tramex.
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®-381 on Sikafloor®-150/-151 allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 hours | 4 days |
| +20 °C | 12 hours | 2 days |
| +30 °C | 8 hours | 1 day |
Before applying Sikafloor®-381 on Sikafloor®-381 allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 hours | 48 hours |
| +20 °C | 18 hours | 24 hours |
| +30 °C | 6 hours | 12 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
