Anti-Condensation Coating - Condensation Specialists

Over time, condensation problems often lead to mould growth, which can be unsightly, damage decorative surfaces and can even cause health problems.

Condensation can appear on walls at any time of the year, but it is most common during the colder months. This is because walls drop in temperature and provide cold spots for condensation to form, and therefore mould to grow.

Sometimes condensation can be solved by minor adjustments to activities that create excess moisture in a property - cooking, washing, cleaning and drying clothes. But this isn’t always enough to stop damp walls and mould growth from returning, and you may need professional solutions for ventilation and thermal improvements. Anti-condensation paints are an option to help prevent moisture laden air condensing on cold surfaces.

We can provide you with a condensation survey to fully understand your condensation problem, with specialist advice and recommendations, no matter where you are in the UK. We have been helping homeowners, social housing providers and commercial partners across the country with solutions for condensation problems for decades.

Anti-condensation paints are specially formulated coatings designed to prevent moisture condensing on cool surfaces. They create a thermal barrier between the cold wall and the warm humid air within the property. As the air is insulated against the colder wall surface by the thermal insulation, condensation will not condense on the surface and this prevents mould growth. Anti-condensation paints often contain tiny glass vacuum bubbles mixed in a paint base.

Anti-condensation paints should not be confused with fungicidal or mouldicidal paints which contain a fungicide to kill mould. These do not insulate, so condensation will still form and run down the wall, but mould will not grow on the surface.

Anti-condensation paints do reduce the formation of condensation by adding an extra layer of insulation to walls and ceilings through utilising glass bubble technology. This thermal barrier helps prevent mould growth. The anti-condensation paints Peter Cox use have been laboratory tested and shown to drastically reduce the formation of condensation.

The glass bubbles are hollow spheres that act as miniature thermos-like bottles helping reflect thermal energy away from the walls. This directs the warm air back into the room and therefore prevents the warm humid air from condensing on the cold surface. This means that it will prevent water droplets forming and running down the walls.

Walls treated with the anti-condensation paint actually feel warmer to the touch because the heat from your hand is being reflected back, instead of being drawn to the colder surface of the wall and escaping.

It is a useful product for small areas of condensation caused by cold bridging, but it will not address the source of moisture in the room. To remove the warm humid air you will need to increase ventilation, typically through an extractor fan or PIV unit.

For large scale condensation problems caused by cold bridging on walls you may require thermal plastering, which is a system designed for properties constructed with solid walls.

This is why it is important to carry out a condensation survey to fully understand the internal environment of your property, and to provide the best solution to the problem.

• Prevents condensation forming on walls
• Inhibits mould and fungal growth
• Ideal for small areas of condensation caused by cold bridging
• Can be used in areas difficult to insulate such as eaves voids or sloping ceilings.
• Can be applied directly on a number of surfaces, where you need it
• It can be painted or wallpapered over without impacting performance
• Prevents heat escaping through cold walls, therefore helping reduce heating bills and reducing your carbon footprint.
• Perfect for kitchens, bathrooms, utility rooms and lintels over doors or windows that suffer from cold bridging

If the wall is damp then an appropriate mould cleaner solution will need to be used before any wallpaper is stripped back and the wall cleaned and sanded to prepare a smooth, flat surface.

Gently fold the paint and pour into a tray. The anti-condensation paint can be applied by brush or roller. Once the first coat has dried (approximately after 4 hours) a second can be applied.

The second coat should be quicker to dry - just around two hours, however we recommend waiting for four hours after application before you paint or wallpaper over it.

When you have a problem with condensation and mould in your property you want advice and solutions that will work long term. This is why you should use a company with experienced and specialist surveyors. This means they have the right training and knowledge to reach the proper diagnosis and provide long term results.

Peter Cox have been the experts in property preservation since 1951 and can provide you with expert advice through a condensation survey, with findings detailed in a survey report. We will also provide you with condensation control measures to prevent the condensation and mould problem, including the application of anti-condensation paints, where necessary.

We have both CSRT and CSTDB qualified surveyors operating from a network of local branches across the UK.

  What is the difference between anti-condensation paint and damp proof paint?

  The key difference is that the anti-condensation paint is designed to stop damp problems where the moisture is coming from inside the property, whereas damp proof paints such as tanking slurries or masonry protection creams prevent damp from outside getting into the internal fabric of the building.

  Secondly, an anti-condensation coating provides a thermal barrier that can help retain heat up to five times longer than conventional emulsions. Whereas damp proof paint is often a silicone water-repellent cream or a mixture of cement, aggregates and chemical modifiers, with no thermal properties.

  Can you paint over anti-condensation paint?

  Yes, once anti-condensation paint has been applied, you can paint or wallpaper over it, allowing thermal improvements to your property without impacting the aesthetics.
