How to test for condensation

Test the walls of the building with our Condensation Test Kit and look for evidence of mold - usually 'black spot' - this indicates that you have Condensation forming on the coldest surfaces in the room. Unless you can increase ventilation and heating, consider using our Anti-Mold Paint Additive or Anti-Mould Emulsion Paint - guaranteed for 5 years!

If necessary, treat all plaster with the anti-mold treatment supplied with the paint and then redecorate.

Measure the Relative Humidity - use our Hygrometer to monitor the conditions in each affected room and use the Memory function to check the exact conditions overnight, the time when temperature falls and condensation is most likely. This meter helps you to control the conditions that cause condensation and to monitor the use of your heating, ventilation and dehumidification.
