TROUBLESHOOTING DAMP, COMMON CAUSES &

HOW TO TREAT DAMP PATCHES ON CEILINGS AND WALLS PRIOR TO PAINTING

The common side effects of damp in the home include; re-accuring mould patches, flaking paint and wallpaper peeling back, often with the affected area 'damp' to the touch. Damp can be caused by many different factors inside and outside your home. Before treating and painting over damp patches we recommend you identify what is causing the damp. Common reasons include:

- Condensation in Kitchens & Bathrooms (often due to a lack of ventilation).
- Broken gutters & down pipes, leaving rainwater pouring down exterior walls.
- A lack of damp course in older properties, which helps keep out damp from the ground.
- A collection of Soil or Debris collecting moisture, that may have travelled above an existing damp course.


N.B. Whilst paint systems can be effective in reducing some of the effects of damp, they are no substitute for dealing with the root cause, so you must diagnose damp & deal with it appropriately. Once the cause of damp is dealt with you are often left with stubborn stains, which persistantly show through--no matter how many times you paint! To prevent damp stains coming back you can use a number of different coatings.

 

Painting Over (Often Mouldy) Damp Patches

Using a product like Zinsser mould killer and remover, apply following instuctions carefully to kill the mould spores, then leave to dry.

We strongly recommend you seal the stain with a quality, trusted brand, so why not use either: 

Zinsser Coverstain

-or-

 

Zinsser B I N primer


You Might Also Need: Zinsser B-I-N Brush Cleaner & Restorer (500ml or 1L)

These products will 'seal' the stain and allow you to paint or paper over them, without damp stains bleeding back through.

We cannot stress enough though that these coatings are not necessarily a permanent solution if you have yet to tackle the underlying cause/s. Other products available at Glenwoods that are effective at helping to either reduce the risk of problems due to condensation or treat damp include:

Johnstones: Stain Block Paint
Johnstones: Damp Proof Paint
Johnstones NOP : Kitchen & Bathroom paint
Johnstones: Anti Condensation Paint
