Another reason to use anti-condensation paint is its durability, you can wipe down this paint because it’s very hard-wearing and will not fade.

This type of paint is great for bathrooms, kitchens and rooms susceptible to mould growth because of an external wall.

It can stop walls from collecting moisture by using Infrared reflectivity which slightly warms the paint greatly reducing condensation.

These specialist paints will act as a barrier that can be wiped and scrubbed daily if needed.

If any room in your house has wet walls or ceilings then there is an airflow issue, you would need to install a fan or air vents in the windows to stop your moisture accumulation.

What Are The Causes Of Condensation And Mould?

There are many causes of condensation, it can be because of rising damp, leaks from pipes or broken roof tiles.

The most common cause of condensation and black mould is when your house or room becomes humid and it’s cooler outside.

So when the humid air comes into contact with a cold wall it will cause droplets to form.

If you have condensation for long periods you will notice black spots of mould growing over your paint.

You can wipe these down but you need to get to the root of the problem to correctly rectify your damp issue.

  • Bad cavity wall insulation
  • Leaking roof tiles
  • Rising damp issues
  • Dripping pipe
  • Damaged drainpipe system
  • Moss or blocked guttering
  • Humid air with no airflow
  • No extractor fan in the bathroom
  • No vents on the windows

There are many reasons why you may be experiencing mould growth and condensation.

Use the list above and check each scenario, it will be one of the issues mentioned above. The most common being bad ventilation, old windows with no air vents.

Applying Anti-Condensation Paint

Before applying your anti-condensation paint you must follow these simple rules for your wall or ceiling to feel the full effects of this type of paint.

We always advise our readers to gently sand down the previous paint so the new paint has a key when dry.

This also removes any grime or grease from your walls. Which might make your new paint bubble or crack. Sugar soap is perfect for this type of gentle paint removal.

  1. Rough your wall with 220 grit sandpaper
  2. Use sugar soap because it’s abrasive and also removes grease
  3. Open windows and doors because it can be over-powering
  4. Wear protective clothing, mask and goggles
  5. Cut your paint in first with a good paintbrush
  6. Then use a roller and apply in lanes up and down so you do not miss a spot
  7. This also goes for the ceiling, cut in the edges and roller in lanes

Give this paint a good 12 hours to dry, leave a window open while this paint dries so it does not get too wet when in the drying stage.

We would advise you to use two coats of this paint, but do not apply the next coat until the first layer has dried.

Conclusion – Anti-Condensation Paint

If you are stuck with a room, bathroom or kitchen that accumulates condensation on the walls or ceilings then you must seek help and install a fan or window vents.

Another reason why a room would have condensation is because of external walls (No cavity wall insulation).

When a wall is warm on the inside and then cold on the outside your walls will accumulate condensation.

For this reason, we would advise you to paint the walls using the anti-condensation paint listed above.
