Tips for mould prevention:

  • Keep the relative air humidity at approx. 50 %.
  • Keep temperature in all rooms equal, the temperature difference between individual rooms should not exceed 5 °C.
  • Keep doors to cooler rooms closed, e.g. to unheated bedrooms, in order to prevent warm and thus damp air from the other rooms from condensing on the walls.
  • Cross ventilate rooms 3-4 times a day
  • Use controlled ventilation systems).
  • Discharge moisture from showering or cooking to the outside immediately.
  • Do not dry laundry in the flat.
  • Leave at least 5 cm distance between furniture and outer walls.
  • Use vapour permeable construction materials and wall coatings, e.g. all products from the ProNature paint range.
  • Find cold bridges: Insufficiently insulated structural components cool down the inner walls, where air humidity then condenses.

Coverage: Approximately 9 – 14 m²/litre, depending on substrate.

Apply with suitable spraying equipment, brush or sponge to the affected areas and allow a residence time of approx. 60 minutes, longer in case of severe infestation. Then wipe off residual mould or rinse off with water.
