Application
Product Temperature
+10 °C min. / +30 °C max.
Ambient Air Temperature
+10 °C min. / +30 °C max.
Relative Air Humidity
80 % max.
Dew Point
The substrate and uncured floor products must be at least +3 °C above dew point to reduce the risk of condensation or surface damage of the floor finish.
Substrate Temperature
+10 °C min. / +30 °C max.
Substrate Moisture Content
≤4 % parts by weight
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).
Applied Product Ready for Use

(1) Depends on roughness depth Rz (all values at +23 °C)
- Rz = 0,0: ~1,9 kg/m2
- Rz = 0,5: ~2,5 kg/m2
- Rz = 1,0: ~3 kg/m2
(2) Depends on temperature
- +23 °C: Filling 1:0,5 with quartz sand 0,1–0,3 mm
- < +15 °C: Filling 1:0,4 with quartz sand 0,1–0,3 mm
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
