A wall that is affected by penetrating dampness, such as leaking or overflowing guttering can usually be easily repaired.
- Find source of penetraing damp problem and repair it as soon as possible, i.e. fix or replace guttering. If you need a reputable builder to repair the penetrating dampness cause, try the FMB find a builder website.
- Promote drying of the internal wall surface that has been affcetd by penetrating dampness, ideally use a dehumidifier and/or air moving fan to promote rapid drying. Tenting (using plastic sheeting to focus the dry air from the dehumidifier to the affected area) can speed up this process and dry the area affected by penetyrating dampness. Be aware that the drying process can take a long time especially if the penetrating dampness has been occuring for a long time. It is important to make sure all walls, floors and ceilings are dry and there are no timbers which are left damp as they will be at high risk of fungal decay.
- Once dry, redecorate. If there is staining or salting, the area will need to be prepared using a stabiliser or stain blocker. If the problem is long term and there is significant salt contamination or blown plaster, then some re-plastering may be required. Zinsser offer a wide range of surface prepartion products and stain blockers. These products are available at all good decorating wholesalers.
