Best Paint for Mould-Prone Areas (Bathrooms, Kitchens, More)

Mould is more than just an unwelcome sight on your walls; it’s a health risk, a sign of deeper moisture issues, and a challenge many homeowners face, especially in damp areas like bathrooms, kitchens, and basements. If you're constantly scrubbing the same patches of black or green spots off your ceiling, it's time to consider a long-term solution: choosing the right paint. The good news is that not all paint is equal, and with the right one, you can actively prevent mould growth and protect your home.

Why Mould Forms in the First Place?

In rooms with high humidity or poor ventilation, moisture tends to linger. That’s where mould spores find the perfect breeding ground. Bathrooms, with their constant steam from showers and baths, are especially vulnerable. Kitchens also deal with daily condensation from cooking, boiling, and washing up. Basements, laundry rooms, and utility areas often suffer from poor airflow and damp walls. Once established, mould can irritate the eyes, skin, and lungs, and even trigger allergies or asthma. That’s why mould-resistant paint isn’t just about looks, it’s about creating a safer indoor environment.

What Makes a Paint Mould-Resistant?

When shopping for paint, look for options labelled “anti-mould,” “mould-resistant,” or “bathroom/kitchen paint.” These are typically formulated with fungicide additives that kill or inhibit the growth of mould and mildew. Another key factor is the finish. Matte finishes tend to absorb moisture, which can encourage mould growth. Instead, opt for finishes like satin, eggshell, or semi-gloss, which are more resistant to moisture and easier to clean. Washability also matters; high-quality paint should allow you to wipe down surfaces without damaging the finish.

The Best Paint Types for Damp Rooms

Paint in moisture-prone rooms needs to work harder than anywhere else in your home. It must withstand steam, heat, splashes, condensation, and, most critically, resist mould and mildew over time. Choosing the wrong paint can lead to bubbling, flaking, or even worsening the mould issue, especially if applied to already compromised walls.

Here’s a closer look at the best-performing paint types and industry-trusted brands that are specifically designed to tackle damp environments.

1. Anti-Mould Emulsion Paints

These are specially formulated with fungicidal agents that actively prevent mould spores from growing on the paint surface. Ideal for ceilings, upper walls, and spots exposed to high humidity, anti-mould emulsions are a must in bathrooms, shower rooms, and laundry areas. They often come with guarantees lasting up to 5–6 years and are breathable, allowing moisture to escape from the wall without trapping it inside, a key feature in older homes.

Recommended Products:

• Dulux Easycare Bathroom+ This product is one of the most popular anti-mould options in the UK. It uses MouldTec™ technology to prevent mould for up to 5 years and is 10x tougher than standard emulsion, resisting steam and splashes. It's available in a wide range of colours and finishes.

  
  

• Acrylic Eggshell and Satin Finishes

While emulsions are great for general wall use, kitchens and utility spaces demand something even more durable and clean. Acrylic eggshell and satin finishes are ideal for walls that face food splashes, grease, and frequent scrubbing. Their slightly glossy finish resists moisture and grime much better than flat matt options.

They’re best used on:

• Kitchen walls around sinks, cookers, and worktops

• Lower bathroom walls (especially in family homes)

• Utility rooms where dryers release steam

• Behind radiators or towel warmers

Recommended Products:

• Benjamin Moore Aura® Bath & SpaA US-based premium brand available in the UK through select suppliers. This is a low-sheen, mould-resistant paint formulated for steamy environments like spas and wet rooms. It’s eco-friendly with low VOCs and is prized for long-term durability.

  
  

• Mould-Resistant Primers and Sealers

If you’re painting over walls that previously had mould, or where condensation is frequent (like above showers or in window corners), a standard topcoat won’t be enough. You need a mould-inhibiting primer to seal the surface and prevent spores from bleeding through the new paint.

These primers create a barrier and help the paint stick better to difficult or previously stained surfaces. They’re also useful on:

• Plasterboard

• Bare masonry

• Previously painted surfaces showing discolouration

Recommended Products:

• Dulux Trade Sterishield Primer Designed for healthcare, commercial kitchens, and bathrooms, it pairs with Dulux’s Sterishield Diamond Matt for a two-part antibacterial and anti-fungal system.

  
  

• Anti-Condensation Paints (for cold surfaces)

In some homes, particularly older buildings or rooms with cold exterior walls, condensation becomes a major problem, especially around window frames or in corners where warm, moist air hits a cool surface. In such cases, anti-condensation paint is a smart choice. These paints work by insulating the wall surface slightly, raising its temperature so that moisture doesn’t condense and creating mould-friendly dampness.

Recommended Products:

• Coo-Var Anti-Condensation Paint A thermal paint that reduces cold spots and discourages moisture from settling on the wall. Best for bedrooms, cold bathrooms, or shaded areas of the house.

  
  

Don’t Just Paint Over Mould, Fix It First

Before reaching for a paintbrush, any existing mould must be properly removed. Painting over mould won’t kill it will just trap it behind a fresh coat, allowing it to reappear later. Begin by cleaning the affected area with a mould-killing solution. A commercial anti-mould spray works well, or you can use a mixture of water and bleach. Scrub thoroughly, rinse and allow the surface to dry completely. If the wall feels damp or shows signs of a leak, investigate and repair the source of the moisture before painting. For areas that have been repainted multiple times or show signs of damage, sanding down the old layers and applying a specialist sealer or stain-blocking primer will improve adhesion and mould resistance.

Best Rooms to Use Anti-Mould Paint?

Bathrooms are the most obvious place. Warm, moist air from showers creates the ideal climate for mould, especially on ceilings, behind toilets, and around windows. Anti-mould emulsion paint, paired with an extractor fan, is the best defence. Kitchens need paint that can stand up to both humidity and grease. Around the stove and sink, use a scrubbable satin finish that repels moisture and is easy to clean. For ceilings, a breathable anti-mould paint works well. Basements and utility rooms are often unheated, making them prone to condensation. Use a primer that can handle damp surfaces, followed by a mould-resistant paint. These rooms also benefit from added ventilation or a dehumidifier to reduce moisture levels. Laundry areas and small bathrooms should be painted with a washable, steam-resistant formula, especially near ceiling corners or behind appliances where air tends to stagnate.

How Ventilation Supports Your Paint?

Even the best paint can’t work alone. Ventilation is key in preventing moisture build-up and, by extension, mould. Make sure your bathroom has an effective extractor fan that runs for at least 15 minutes after every shower. In the kitchen, use a cooker hood or open windows regularly when boiling or frying. If you live in a humid region, investing in a small dehumidifier can drastically improve long-term air quality and reduce the risk of mould on walls.

Eco-Friendly Anti-Mould Paints

For families with children, allergy sufferers, or anyone concerned about indoor air quality, look for low-VOC or VOC-free options. Some eco-friendly paints now include anti-fungal ingredients while still meeting safety and environmental standards. These are especially useful for nurseries, bedrooms, or homes with sensitive occupants. Brands that meet EU Ecolabel or BS EN 16516 indoor air safety standards are a good place to start.

Can I Use Regular Paint in Bathrooms or Kitchens?

Technically, yes, but you’ll likely find yourself repainting sooner than you'd like. Regular emulsion or matte paint absorbs steam and becomes a food source for mould. Plus, it's harder to clean, so stains and discolouration are harder to remove. If budget is a concern, consider using mould-resistant paint only in high-risk areas, such as the ceiling, behind the shower, or above the cooker and use a more affordable paint elsewhere.

Should I Hire a Professional?

If the mould has already caused visible damage such as bubbling paint, crumbling plaster, or dark stains spreading across a ceiling, it’s best to call in a professional. A skilled painter can remove affected layers, seal the surface, and apply the right products that will last. They also understand drying times, proper layering, and how to cut moisture off at the root.
