HBW – lightness coefficient
According to the recommendations of the Polish Building Research Institute (ITB), a maximum of 10 % of a façade surface should be painted with colours with a lightness coefficient (HBW) of less than 20.
If it is necessary to use a dark colour on more than 10 % of the façade surface, a suitable reinforcement layer adhesive should be used for render with the following lightness coefficients (HBW):
– HBW 20-15 – system with adhesive mortar Stopter K-50, Stopter K-20
– HBW 15-10 – system with adhesive mortar Stopter K-50 or Stopter K-20,
– below 10 – for maximum 10 % of the façade surface or upon individual consultation with the manufacturer.
