Application
Product Temperature
+5 °C min. / +30 °C max.
Ambient Air Temperature
+5 °C min. / +30 °C max.
Relative Air Humidity
35 % min. / +80 % max.
Dew Point
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
+5 °C min. / +30 °C max.
Substrate Moisture Content
Sikafloor® MonoFlex MB-25 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.
