The Best Anti Condensation Paint To Buy In 2022

Condensation is a common issue in many households. The moist patches not only produce unsightly stains on the ceilings and walls, but also also encourages the growth of mould and mildew. Apart from aesthetics, these fungus can induce allergic reactions and respiratory irritation.

That’s why using a high-quality anti-condensation paint on your walls is critical. But how do you find a reliable product that actually fixes the problem rather than merely masking it?

It’s annoying to paint your walls with anti-condensation paint just to discover that the product isn’t as good as stated. That’s why our team of experts has put the most popular anti-condensation paints in the UK to the test and graded them. Take a look at our top choices below.

Finding a decent anti-condensation paint is difficult, but Coovar wowed us with its outstanding qualities. The solution performed admirably in places prone to airborne dampness, such as bathrooms and kitchens.

The paint comes in 500ml tins and is only available in one colour: white. The product dries to a slightly textured matt finish and is suited for use on plaster, wood, metal, and brick and can be used as a topcoat or an undercoat.

Although the paint is simple to apply with a brush or roller, it has an odd consistency that doesn’t promise much at first. Coovar, on the other hand, eliminates and prevents condensation and related concerns because to its short drying time and long-lasting finish.

Our favourite feature was that, despite the fact that the paint may be covered with emulsion, it has a lovely finish on its own. Coovar provides long-lasting benefits thanks to ingredients that minimise moisture-induced discoloration.

Of course, this paint isn’t a magic wand, and if your environment has a lot of moisture, the product may struggle to keep the surface dry. In this scenario, we recommend addressing the source of condensation first, such as sufficient insulation or ventilation, before applying Coovar to the walls.


• A fungicide in a high-quality formulation prevents the growth of unattractive mould.
• Tins of 500mL, 1L, and 2.5L Coovar are available. A litre of paint covers up to 10m2, and the manufacturer suggests at least two coats for best results.
• This paint touch-up takes 2 hours to dry and 4 hours to re-coat. Allow the product to dry completely before applying the emulsion.
• Water-based paint is suitable for use in confined spaces. It has a minimal odour and has very few hazardous components, making it ideal for usage in household and communal settings such as kitchens, baths, and locker rooms.


• It takes two coats to effectively treat any surfaces affected by excessive condensation, and the product must be stired regularly during usage to guarantee an even distribution of the biocidal agent.

Polycell offers a low-cost anti-condensation paint. Damp Seal is a moisture-resistant undercoat used to seal damp spots on interior walls and ceilings. Despite its inexpensive price, the product comes highly recommended by Dulux and has excellent quality.

Damp Seal comes in a white colour and dries to a matt surface. It can be painted over with any emulsion, but it isn’t required. Once dried, the product prevents moisture from permeating the coating, resulting in a long-lasting perfect finish.

Damp Seal may be used on a variety of surfaces, making it extremely versatile. If the surface is properly prepared and primed, the product can be applied on indoor plaster, brick, stone, and cement.

Damp Seal, like any other product on the market, has limitations and drawbacks. Some customers expressed dissatisfaction with the lengthy drying time, while others stated that more than one layer may be required to completely seal the surface.

We couldn’t complain about the drying time in optimum conditions, however it was a little longer than typical. Despite their “one-coat” guarantee, we can affirm that it takes two or more coats to produce satisfactory results.


• Polycell Damp Seal is available in 500ml, 1L, and 2.5L tins and offers excellent value for money. For fast jobs, an aerosol version is also available.
• Damp Seal dries to a matt white finish and can be used as an undercoat or topcoat. Most interior wall and ceiling emulsions are compatible with it.
• Impressive coverage: depending on surface porosity, this anti-condensation paint can cover up to 14m2/litre.
• The product’s thick consistency makes it simple to apply without making a mess. You can use a brush or a roller to apply Damp Seal.


• Damp Seal touch dries in four hours, which is slightly longer than the industry standard. It can be re-coated after around 12 hours if necessary; if you wish to coat it with emulsion, you may need to wait up to a week for the product to harden.
• The packaging has problems in the design that make it difficult to reopen once the lid has been replaced after the first use.

HQC is a fantastic anti-condensation paint that acts as an insulator, minimising heat loss in your home while also preventing serious condensation issues including discoloration, scorching, and staining.

It should be noted, however, that this paint is not specifically intended to prevent mould development or water penetration; you would need to purchase a specialised product to address any of these issues.

Despite this, HQC anti-condensation is a fantastic product. It has a non-toxic, water-based recipe that is environmentally friendly. The solution is ideal for use in any settings where conventional emulsion would be used, including bathrooms and kitchens, basements, attics, swimming pools, and spas.

The product is available in 32 colours and can be used as an undercoat for wallpaper and emulsions or on its own. The colour range is made up of a variety of neutral and dramatic tones that dry to a slightly textured matt finish.

The product is available in 500ml, 1L, 2.5L, and 5L tins for your convenience.


• HQC anti-condensation paint protects the walls for a long time by acting as an insulator and keeping them from becoming too cold.
• The product is simple to apply with a brush, roller, or sprayer, and two coats are usually sufficient.
• This paint touch-up takes two hours to dry and four hours to recoat. The product may take up to 24 hours to completely dry.


• Coverage is limited — a litre of paint will cover up to 6m2. This paint may not be suitable for large projects due to its high cost.
• The colour chart is wildly wrong, with hues that are frequently lighter or darker than intended.

In the same way that HQC paint functions as an insulator on the wall, Ronseal Anti Condensation paint prevents heat loss and condensation. The product, however, does not contain any biocidal chemicals and will not prevent mould from spreading if it already exists.

The coverage is another resemblance. Both paints have a coverage of up to 6 m2/litre. The colour range, however, is a significant distinction. Ronseal is only available in White Matt and can be overcoated with any interior wall and ceiling emulsion.

The matt finish has a sand-like feel, and the paint is quite thick. Although it dries wonderfully on walls, the thickness and texture of the paint will necessitate painting the entire surface, not just the condensation-affected area. This can result in an extremely expensive redecorating effort.

Anti-condensation Ronseal is available in 2.5L tubs and can be applied with a brush or roller. Two coats are normally required for full coverage, but because to the short drying time, you’ll be able to complete the project in no time.

We also enjoy the paint’s versatility, as it can be used as an undercoat for both emulsion and wallpaper.


• Washable product touch dries in two hours and may be re-coated after four hours. • Water-based product is safe to use in poorly ventilated environments and easy to clean off brushes with soapy water. Allow at least 24 hours for the paint to cure before applying emulsion or wallpaper.
• Ronseal Anti Condensation can be used on interior walls and ceilings that are both bare and previously painted.


• This product is costly, and it isn’t designed to prevent mould growth or water intrusion in the walls.

Another product with various properties is Thermilate InsOpaint Anti-Condensation. This paint, like the others mentioned above, can be used as an undercoat or as a stand-alone application. It comes in 24 colours and dries to a slightly textured matt finish.

The product can be used on a range of surfaces, including previously painted wallpaper, to prevent the most frequent condensation problems. This anti-condensation paint can also be used as an undercoat for wallpaper or interior wall and ceiling emulsions.

The product avoids condensation by limiting heat loss by acting as an insulator. This not only keeps your walls looking great, but it also saves you money on your energy bill.

The paint comes in 5L containers and is designed to go a long way. A litre of paint covers up to 14m2 and only two coats are required for complete coverage.

The product is non-toxic and safe to use in the presence of children and pets because it is water-based and environmentally friendly.


• The product may be applied with a brush, roller, or sprayer due to its optimum viscosity. • InsOpaint eliminates the most frequent condensation problems such as mould, discoloration, staining, and more. This is one of the most cost-effective anti-condensation paints available.


• The finish is textured more than expected – this isn’t a huge flaw, but it irritated several people.


Moisture build-up can be caused by a variety of factors, including inadequate exterior wall insulation, wall deterioration that allows water infiltration, and even a lack of ventilation.

The golden guideline for preventing moisture build-up is to ensure that the rooms are well ventilated. Anti-condensation paint can also help prevent moisture build-up in high-moisture areas like the kitchen and bathroom.

Make sure your home is properly ventilated by airing the rooms for at least 10 minutes each day: we propose installing an extractor fan in the bathroom and cooking with the kitchen hood.

Laundry is a significant source of moisture, and drying it incorrectly can result in condensation and moisture build-up. Dry your laundry outside or in a tumble dryer if possible. Place the rack close to an open window if you must dry it indoors.

It’s also a good idea to turn on the electric ventilation system at least four times a day. If your home has air vents in the walls, make sure they aren’t blocked. Modern vents are designed to reduce heat dissipation while yet providing adequate ventilation.

Moisture build-up can also be caused by fine fractures and defects in the wall, which promote water infiltration. Check the outside walls and roof for leaks on a regular basis to ensure they are completely sealed.

Check the joints of the sinks, bathtub, and shower on the inside, as they may leak and cause water penetration.

Finally, if you observe water infiltration or moisture build-up, consult a professional to determine the source of the problem. In the long term, hiding the moisture by painting the walls with a waterproof solution may be counterproductive.

Wait for the surface to dry before treating it with an anti-damp or anti-condensation product after you’ve assessed and remedied the problem.

How to Select the Best Anti-Condensation Paint

You may find it difficult to choose the best anti condensation paint because there are so many possibilities.

Naturally, you’ll want one that’s inexpensive, simple to use, and offers a good level of protection.

As a result, we’ve supplied a few pointers to assist you in deciding which anti-condensation paint is best for you:

The Price Tag

One of the things you should consider is the price of the paint, which can range significantly across manufacturers and merchants.

It can also vary depending on the amount of paint in the can. So, not only should you examine pricing, but you should also consider the other crucial elements.

Amount of Paint

Anti condensation paint comes in a variety of sizes, including 750ml, 1 litre, and 2.5 litres.

So, figure out how much paint you’ll need to cover the surfaces you want to treat, and then double-check the amount of paint in the can.

You may need more than one can depending on how much you need to cover your surfaces. Remember that you might need to apply a second layer.

Number of Coats

Following up on the last step, double-check to see if two coats are required, as well as whether a primer is required.

This will influence the quantity of cans you need to purchase in order to cover the required areas. It will also affect the length of time it takes to complete the job.

Time to Dry

While the drying time for the paint is not something that will necessarily influence your decision, it is worth investigating. Most anti-condensation paint dries to the touch in 1-2 hours, but others may take longer.
Online testimonials

Finally, before you make your final decision, make sure you read reviews from other individuals who have used the paint. You will have no idea what the outcome will be if you have never done it before.

However, you may learn more about this by looking at other people’s experiences. You will be able to make a far more informed decision as a result of this.

Is Anti Condensation Paint Effective?

Let’s be clear: even the best anti-condensation paint isn’t a 100% guarantee against condensation.

It works by insulating the wall and preventing the temperature of the wall from decreasing to a point where condensation can occur. While it works, it will only help with small condensation problems.

If your condensation problem is severe, you may need to use other measures to reduce it, such as a positive pressure ventilation system.
Is Anti-Mould Paint And Anti-Condensation Paint the Same Thing?

In a nutshell, no. While the two types of paint serve the same purpose (to solve a problem on walls caused by excessive moisture), they approach the problem in different ways.

A fungicide is included in the best anti-mold paints to help kill any mould spores. On the other hand, the best anti condensation paint helps to insulate the wall and prevent moisture from accumulating.

How Do You Cover Condensation With Paint?

It’s critical to use the proper product when painting walls that have been impacted by dampness. To help with this problem, you should look for a high-quality anti-condensation paint.

Not only that, but you must follow the instructions to the letter in order to receive optimum protection.

This includes allowing the paint to cure for the stated amount of time and, if necessary, applying a second layer.

Simply said, you apply anti condensation paint to help combat condensation on walls the same way you would any other paint.

However, because some of these paints rely on complex technology and particular processes to produce an effective product, it’s critical to read the instructions rather than assume.

This will ensure that you do the task appropriately based on the product you purchase, resulting in more effective protection.

What Causes Wall Condensation?

Condensation on interior walls may be a major issue, and it’s especially aggravating when it appears out of nowhere.

Condensation occurs when hot moist air comes into contact with cold, dry air. Drops of water form on the cooler surface, i.e. your walls, when the two contact and merge.

When you take a hot bath or shower in your bathroom, you will most likely witness examples of this.

When you exit, you may notice water droplets trickling down the walls, which is the result of the condensation process. This is what happens when hot, moist air from your bath or shower collides with the cold, dry surface of the walls.
Is Wall Condensation a Problem?

It is critical to take action if you have a condensation problem in your home. This is due to the fact that condensation can be a severe problem in your home.

If you have condensation on the inner walls of your home, you may have a variety of problems, which are not limited to your home’s visual appeal.

The impact of condensation on the walls is that it can cause stains and unsightly marks, which can detract from the aesthetic of your home. However, it can lead to more serious problems in your home, such as the growth of mould and mildew.

This is not only unsightly, but it can also put your family’s health in jeopardy.

If you have elderly folks or little children in your home, mould, mildew, and damp can be dangerous to their health.

Similarly, if you have someone in your home who already has respiratory problems, it can be quite harmful to their health. This is why it is critical to address condensation concerns as soon as possible rather than allowing them to fester.

Dealing with condensation and mould concerns has gotten much easier thanks to the high quality of the best anti condensation paint treatments on the market.

All you have to do now is find the proper one and follow the instructions to the letter.

Also, if a second coat is required, be sure you don’t forget to apply it. After that, you may expect a much greater level of protection against dampness and mould in your home.
