Application
Product Temperature
+10 °C min. / +30 °C max. For the spray applied membrane refer to the individual Product Data Sheet.
Ambient Air Temperature
+10 °C min. / +30 °C max. For the spray applied membrane refer to the individual Product Data Sheet.
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
+10 °C min. / +30 °C max.
Substrate Moisture Content
Sikafloor® MultiFlex PB-54 UV can be installed on substrates with moisture content of max. 4 % (checked by Tramex). The substrate needs to be visibly dry and have an adequate pull-off strength min 1.5 N/mm2. Check for rising moisture.
