Application
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 temperature must be at least 3 °C above the 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
Can be applied on green or damp concrete with no standing water.
Although the system can be applied onto green concrete surfaces (> 24 hours), it is advised to allow at least 3 days for early concrete shrinkage to occur in order to prevent shrinkage cracks from appearing on the wearing surface.
Waiting Time / Overcoating
Before applying Sikafloor®-81 EpoCem® on Sikafloor®-155 WN allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 12 hours | 72 hours |
| +20 °C | 6 hours | 48 hours |
| +30 °C | 4 hours | 24 hours |
Sikafloor®-81 EpoCem® can be overcoated with vapour impermeable coatings when the surface humidity falls below 4 %.
Not earlier than :
| Substrate Temperature | Waiting Time |
| +10 °C | 2 days |
| +20 °C | 1 day |
| +30 °C | 1 day |
Before applying Sikafloor®-264 N on Sikafloor®-263 SL N allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 30 hours | 72 hours |
| +20 °C | 24 hours | 48 hours |
| +30 °C | 16 hours | 24 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity
