Mould

Mould/fungi mainly occur in high humidity places such as bathrooms and kitchens.  As a rule of thumb: no mould without moisture. In the bathroom, mould occurs mainly on the ceiling and in between the grouting of the tiles especially around the shower area. Cleaning and preventing mold is the responsibility of the tenants.
 
Make sure grouting is regularly cleaned with ordinary detergent. Daily domestic activities make the house more humid such as cooking, use of tumble dryer, showering.  One person emits 5 liters of fluid per day just by breathing.  Remember that mould grows faster in corners where air circulation is poor.
 
The best methods to prevent mould growth are:

  • Insulate well and sufficiently
  • Prevent thermal bridges
  • Ventilate
  • Use anti-mould paint in humid areas like the bathroom.  Acrylic is good to use.

Tip!

To clean mould from between the tile grouting use an old toothbrush dipped in bleach.  Bleach also kills mould, so a solution of this to wash down the grouting should assist in keeping it mould free.
