1. Dryzone Anti-Condensation Paint
Dryzone Anti-Condensation Paint is made for cold interior walls where condensation keeps forming. For example, behind wardrobes, in the corners, and/or above skirting boards.
The paint contains glass microspheres that help the wall stay slightly warmer. That warmth makes it harder for water vapour to turn into liquid when it comes into contact with the wall surface.
Additionally, the Dryzone Anti-Condensation Paint is also breathable, allowing any existing dampness inside the wall to escape. That reduces the risk of mould growing over time.
Key Features
- Triple-action formula targets key causes of condensation
- Thermal effect maintains a warmer wall surface
- Preservative layer helps prevent mould and microbial growth
- Porous structure buffers moisture and reduces surface damp
- Extends time-to-condensation, allowing moisture to disperse naturally
Why We Recommend It
Dryzone Anti-Condensation paint tackles the cause, not just the stains. By keeping the wall warmer and breathable, it helps stop condensation from returning. It’s truly a practical choice for rooms that stay cold and damp.

2. Wykamol Thermaldry Anti-Condensation Coating, 5L
Wykamol Thermaldry is a thermal paint designed to cut down condensation by insulating the wall surface. It uses hollow glass beads — about 50 microns in size — that work like mini thermos flasks. They slow heat loss through the wall, helping to keep the surface temperature high enough to stop water vapour turning to liquid.
It’s water-based, dries water-repellent, and can be overpainted or wallpapered once cured. Best used on cold internal walls, especially in rooms that trap moisture.
Key Features
- Glass bead tech reduces heat transfer through walls
- Helps raise surface temperature and lower dew point
- Water-repellent once dry
- Suitable for use on plaster, brick, concrete, and more
- 5L tub covers large areas — ideal for full-room treatment
Why We Recommend It
Thermaldry offers proper insulation-grade protection in paint form. You’re not just reducing condensation — you’re making the wall behave more like an insulated surface. That makes it useful in homes with recurring cold spots, especially around lintels or external walls.

3. Rempro Thermal Paint, 2.4L
Rempro Thermal Paint is for cold walls where condensation leads to mould. It’s designed to slow that process down by changing how the wall handles heat.
When the paint dries, it forms a thermal barrier using hollow glass beads. That stops heat escaping through the surface, which means the wall stays warmer, and warmer walls don’t attract condensation as easily.
What you end up with is a finish that feels warmer to the touch and takes noticeably longer to fog up. It’s especially useful in places where insulation is lacking, like single-brick walls or older bathrooms and kitchens.
Key Features
- Slows condensation by keeping the wall surface warmer
- Glass microspheres reduce heat loss
- Water-based and suitable for walls and ceilings
- Can be painted over or wallpapered
- Touch dry in 2 hours, full recoat in 4
Why We Recommend It
This isn’t just anti-mould paint — it actually tackles the temperature difference that causes condensation. It’s simple: if the wall isn’t cold, the moisture in the air doesn’t stick. Rempro does that job well, especially on cold external walls where regular paint never lasts.

4. SmartSeal Anti-Condensation Paint – 2.5L
SmartSeal’s paint is built for homes that get damp easily — the kind where bedrooms feel clammy in winter or you’re forever wiping the bathroom ceiling. This is a dual-action emulsion that cuts down surface condensation and helps block mould spores from coming back. It’s breathable, so walls don’t get sealed in.
The finish is matt and comes in a range of colours, though brilliant white is the most popular.
Key Features
- Acrylic emulsion that reduces condensation by up to 95%
- Mould-resistant barrier for walls and ceilings
- Breathable, low-VOC formula for safer indoor use
- Ideal for cold spots, poorly insulated rooms and bathrooms
- Touch dry in a few hours – apply two coats for best results
Why We Recommend It
SmartSeal is worth a look if you’ve already cleaned the mould but want to stop it coming back. Especially helpful in homes with poor insulation or no extractor fans — it’s been used in rentals, bathrooms, and even behind furniture where walls stay cold.

5. Siramico Anti Condensation Thermal Paint
Siramico’s Anti-Condensation Paint is a water-based thermal coating that works by making cold surfaces feel warmer. It’s slightly grainy to the touch once dry, but that texture plays a part — it helps slow heat loss, which makes condensation less likely to form in the first place.
It’s safe for use indoors or out, bonds to all kinds of materials (brick, wood, tiles, even plastic), and can be overpainted after 48 hours if you want a smoother or coloured finish.
Key Features
- Thermal coating reduces risk of condensation forming
- Bonds to wood, metal, brick, tile, and more
- Water-based, low odour, and non-toxic
- Matt white finish — can be overpainted
- Suitable for interior and exterior use
Why We Recommend It
This one’s good for tricky areas where normal paint peels or fails — like bathrooms, ceilings above showers, or even unheated garages. It grips well, adds thermal resistance, and slows down the cycle that causes mould. Not fancy — just functional.

6. Coo-Var Anti-Condensation Paint, 1L
Coo-Var’s a great option if you’ve got cold walls that keep steaming up or growing mould, especially in corners or behind furniture. It’s packed with tiny glass beads that help the wall hold a bit more warmth, which means less condensation forms in the first place.
It works like a normal paint, but it works harder in the background to prevent damp settling. Just make sure to cover the whole wall, not just the damp patch.
Key Features
- Helps wall surfaces stay warmer
- Matt finish with slight texture
- Built-in mould-resistant ingredients
- Water-based, low odour
- Covers around 8–10m² per litre
Why We Recommend Coo-Var 1L
This one’s not just a cover-up — it actually changes how the wall reacts to moisture. If you’ve got a spot that always ends up damp, even after repainting, this is well worth trying.

7. Ronseal Anti-Condensation Paint
Ronseal’s Anti-Condensation Paint adds a basic insulating layer to stop cold surfaces from collecting moisture. It’s not packed with advanced tech like microspheres, but it does enough to raise the wall temperature just enough to help stop water droplets from forming. Once dry, it leaves a tough, matte finish that can be scrubbed clean without lifting the surface.
You can leave it as is or paint over it with any emulsion. It’s a simple barrier layer for bathrooms, box rooms, or anywhere you keep wiping down condensation.
Key Features
- Matt finishes adds a thermal layer to reduce condensation
- Scrubbable once dry — won’t flake with light cleaning
- Touch dry in 1–2 hours, ready for second coat in 4
- Can be overpainted with any standard colour
- For use on interior walls and ceilings only
Why We Recommend It
This is a no-frills anti-condensation paint that does what it says. It’s not breathable or high-tech, but if you want a quick fix for condensation on cold surfaces — and don’t want to repaint every few months — it’s a decent pick for the price.

This isn’t a specialist thermal coating. It’s a straightforward paint that helps prevent water droplets from forming by slightly insulating the surface.
It’s ideal for small areas, dries quickly, and gives you the option to paint over it once set. Good for bathrooms, utility rooms, or rental touch-ups.
Key Features
- Helps reduce surface condensation in problem areas

- Touch dry in 1–2 hours
- Can be painted over after 4 hours

Best Anti Condensation Paints: Quick Buying Guide
Thermal effect: The best paints help your wall hold a bit more warmth — that’s what stops condensation forming in the first place. Look for ones with things like glass beads or thermal additives.
Stops mould coming back: Some paints just cover stains. Others stop black mould from returning. Always check if it has mould-resistant ingredients — especially for bathrooms or kitchens.
Let walls breathe: Breathable paints are key if the wall’s already been damp. They let moisture escape instead of trapping it underneath the surface.
Works on your surface: Not every paint sticks to every material. If you’re painting brick, wood, tile or metal, double-check it’s made for that job.
Paint over later: Some paints dry in plain white or magnolia but are made to be overpainted. Handy if you want a colour on top.
Low smell indoors: If you’re painting inside, especially with poor ventilation, go for something low-odour and water-based. It’s just a bit more pleasant to use.
How far it goes: 1 litre usually covers around 8 to 10 square metres — but it depends on the surface. Bigger jobs might need a 2.5L or 5L tin.
Drying times: Some are ready for a second coat in a few hours. Others need longer. Don’t rush it — always check the tin first.

Best Anti Condensation Paint Questions Answered
When should I use anti condensation paint?
Use anti condensation paint when cold walls keep attracting moisture — especially in bathrooms, kitchens or bedrooms. It’s most useful during colder months when condensation builds up daily and starts causing mould or staining.
Where to use anti condensation paint?
It’s ideal for internal walls and ceilings that stay cold or damp — like behind wardrobes, near windows, or on external-facing walls. Anti condensation paint also works well in cellars, box rooms, or anywhere ventilation is poor.
How do you apply anti condensation paint
Make sure the surface is clean and dry. Treat any mould first. Then apply one or two coats with a brush or roller. Some anti condensation paints can be overpainted with emulsion once dry — always check the tin.
Should I use anti condensation paint or anti mould paint?
It depends what the issue is. If you’ve got visible mould, anti mould paint is useful. But if condensation keeps coming back, anti condensation paint will do more to stop the moisture in the first place. Some paints combine both.
How long does anti condensation paint last?
It usually lasts 3–5 years. In rooms with good airflow and no major leaks, it holds up well. Just make sure you’ve fixed the root cause too, like poor insulation or no extractor fan — or the problem may return.
Is thermal paint the same as anti condensation paint?
Not quite. Thermal paint focuses on reducing heat loss, while anti condensation paint stops moisture forming on cold surfaces. Some paints do both — they insulate and help prevent mould — so it’s worth checking the label.
How many coats of anti condensation paint?
Most brands recommend two coats for full protection. One coat may work for small areas, but two gives better coverage and keeps moisture at bay longer — especially in bathrooms or on cold, exterior walls.
