Cold internal surfaces affected by condensation and subject to the formation of black mould such as:

  • Solid walls;
  • Pantries and larders;
  • Bathrooms and shower rooms;
  • Kitchens;
  • Ceilings;
  • Elevations exposed to cold winds.


A white thermal coating for use on cold and poorly insulated surfaces. It contains specific mineral powders which, due to their insulating features, warm the surface of the treated wall.

Condensation is formed when warm air, holding water vapour, comes into contact with a cold surface (dew point surface). The air near to the cold surface cools and the cooler air is unable to hold as much water vapour as it was able to when it was warmer. The water vapour that the cooler air is unable to hold is deposited on the adjacent cool surface. The 5°C difference between a surface treated with CWC and one not treated with CWC will, in most cases, take the wall surface temperature to above the dew-point, meaning that the formation of condensation and mould is eliminated. the dew-point, meaning that the formation of condensation and mould is eliminated.
