Ambient Air Temperature

+10 °C min. / +30 °C max.
Relative Air Humidity

80 % max.
Dew Point

Beware of condensation.
The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.

Low temperatures and high humidity conditions increase the probability of blooming.
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).
