3 common mistakes when drying a water damage

  • Dehumidification technology was developed during the Second World War to protect warships and other defense material against corrosion. Today it is an established technology with numerous effective solutions. Unfortunately, it has been difficult to obtain an overview of the various systems available for dehumidification. Firstly, there are so many methods and systems to choose from. Secondly, there are so many drying agents to choose from. Since there are now so many choices available, it’s easier to find the best solution, both practically and economically, on the basis of the requirements of each individual case.

    Water damage restoration can be difficult and include risks. Below you can read about three common mistakes when drying a water damage.

     

    1. DRY TOO MUCH

    When drying spaces that have been damaged by damp, there is a risk that drying can be carried out too quickly (relative humidity sinks down towards 10-20%), Damage such a crack formation in wooden constructions and fittings can likewise occur if the RH falls too quickly down to 10-20%. By controlling the dehumidifier with a hygrostat that registers the relative humidity, these risks can be eliminated.

     

    2. REDISTRIBUTING THE MOISTURE

    When drying a water-filled floor surface, for example, with the help of a fan, perhaps also combined with heat, damp is moved up towards walls and ceiling areas. This can cause the damp to penetrate the construction and come into contact with cold building materials or plumbing systems which in turn condense the water vapour in the warmer damp air and a new damp problem arises. This problem can be avoided by installing enough suitable dehumidifiers.

     

    3. DAMP BARRIERS IN WALLS

    When drying damp-damaged walls, the damp can penetrate the wall and stop at a damp barrier. The damp is sealed in and cannot escape from the wall. The walls can feel dry and even measuring can fail to detect the damp which is still trapped in the wall and – when the tempe­rature falls – will resurface and spread in the wall material.
