Application
Ambient air temperature
+10 °C min. / +30 °C max.
Relative air humidity
During curing the humidity should not exceed 75 % max. Adequate fresh air ventilation or a dehumidifier must be provided to remove the excess moisture from the curing product.
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
<4 % pbw moisture content.
Test method: Sika Tramex Meter, CM-measurement or Oven-Dry-Method. No rising moisture according to ASTM (Polyethylene-sheet).
Waiting time to overcoating
Before applying Sikafloor®-263 SL on Sikafloor-160/-161 allow:
Substrate temperature | Minimum | Maximum |

+20 °C | 12 hours | 2 days |
+30 °C | 8 hours | 1 days |
Before applying Sikafloor®-305 W ESD TopCoat on Sikafloor®-263 SL allow:
Title 1Substrate temperature | Minimum | Maximum |
+10 °C | 36 hours | 7 days |
+20 °C | 24 hours | 5 days |
+30 °C | 16 hours | 3 days |
