Ambient Air Temperature
+15 °C min. / +30 °C max.
Relative Air Humidity
80 % 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 other disturbance of the surface on the floor finish
Substrate Temperature
+15 °C min. / +30 °C max.
Substrate Moisture Content
Sika Comforfloor® PS-27 can be installed on substrates with moisture content of max. 4 % (checked by Tramex). The substrate needs to be visibly dry and have adequate pull-off strength min 1.5 N/mm2. Check rising moisture.
