It's a common scenario many homeowners and business owners face, prompting the question: what paint is best for mould?

Before we go into specific recommendations, let's take a step back and consider the importance of selecting the right paint for tackling mould issues.

Why Choose the Best Mould Paint?

Let's first understand why it's crucial to select the best one for your needs. 

Mould can be a persistent problem in many environments, especially in areas with high humidity or moisture. 

Not only is it unsightly, but it can also pose serious health risks to you and your family or employees.

The right mould paint can effectively kill existing mould spores and prevent them from returning. 

Additionally, it can help to prevent future mould growth, saving you time and money on costly repairs and renovations down the line.

So again, what is the best paint to stop mould?

Now, circling back to our initial question, what is the best paint to stop mould? It's a query that resonates with many facing the challenge of mould remediation. 

However, before we provide a direct answer, let's go into the factors to consider when choosing mould paint. 

Understanding these essential elements, you'll be better equipped to make an informed decision and select the most suitable product for your specific needs.

Factors to Consider When Choosing Mould Paint

When it comes to tackling mould, effectiveness is key. 

Look for a mould paint that is specifically formulated to kill mould spores on contact and prevent them from coming back. 

It's essential to pick a product that has been tested and proven to work effectively in real-world situations.


Mould-prone areas, such as bathrooms, kitchens, and basements, can be subjected to a lot of wear and tear. 

Therefore, it's essential to select a mould paint that is durable and long-lasting. 

Look for a product that is resistant to moisture, mildew, and stains, ensuring that your surfaces stay mould-free for years to come.


The safety of your family, employees, and the environment should always be a top priority. 

Choose a mould paint that is non-toxic and low in volatile organic compounds (VOCs). 

This will help to minimise exposure to harmful chemicals and ensure a healthier indoor environment.

Ease of Application

Let's face it – nobody wants to spend hours slaving away with a paintbrush. 

Look for a mould paint that is easy to apply, whether you're a DIY enthusiast or a professional painter. 

Consider factors such as coverage, drying time, and clean-up to ensure a hassle-free painting experience.

Value for Money

While it's essential to choose a high-quality mould paint, you also want to get the best value for your money. 

Compare prices and consider factors such as coverage area and longevity to determine which product offers the most bang for your buck.

What is the best way to remove mould before painting?

The best way to remove mould before painting involves several steps to ensure thorough eradication and prevent future growth. These are the following:

Prepare the Surface

Begin by preparing the affected surface for cleaning. Remove any furniture or objects from the area to give yourself ample space to work. 

Use plastic sheeting to protect surrounding areas from splashes or debris.

Clean the Surface

Mix a solution of water and detergent or use a specialised mould cleaner according to the manufacturer's instructions. 

Apply the cleaning solution to the affected surface and scrub vigorously with a brush or sponge to remove visible mould and dirt. 

Pay close attention to crevices, corners, and areas with heavy mould growth.

Rinse Thoroughly

After scrubbing, rinse the surface thoroughly with clean water to remove any leftover cleaning solution and debris. 

Use a clean sponge or cloth to wipe away excess moisture and ensure the surface is completely dry before proceeding.

Address Moisture Issues

Mould thrives in damp, humid environments, so it's essential to address any underlying moisture issues to prevent mould from returning. 

Inspect the area for leaks, water damage, or poor ventilation, and take steps to fix any problems you find. 

This may involve repairing plumbing leaks, improving ventilation, or installing a dehumidifier.

Apply Mould-Resistant Primer

Once the surface is clean and dry, apply a mould-resistant primer to create a barrier against future mould growth. 

Choose a primer specifically formulated to inhibit mould and mildew, and follow the manufacturer's instructions for application. 

Be sure to cover the entire surface evenly and allow the primer to dry completely before proceeding.

Paint with Mould-Resistant Paint

After the primer has dried, paint the surface with a high-quality mould-resistant paint. 

Look for paint labelled as mould-resistant or mould-inhibiting, and decide a colour and finish that suits your preferences. 

Apply the paint evenly using a brush, roller, or sprayer, and allow it to dry completely between coats. 

Multiple coats may be necessary for complete coverage and maximum protection against mould growth.

By following these steps, you can effectively remove the mould before painting and create a clean, healthy surface for your paint job. 

Remember to take proper precautions when dealing with mould, such as wearing protective clothing and ventilating the area, and consult a professional if you're unsure about how to proceed.

Is it good to paint over mould?

Painting over mould is generally not recommended, as it can lead to several issues. 

While paint may temporarily cover up the appearance of mould, it does not address the underlying problem and can actually exacerbate the issue over time.

Here's why it's not advisable to paint over mould:

Mould Growth Continues

Painting over mould does not kill the mould or prevent it from growing further. 

Mould can continue to thrive beneath the paint layer, spreading and causing damage to the underlying surface.

Health Risks

Mould can release spores and mycotoxins into the air, which can pose serious health risks, especially for individuals with respiratory problems or compromised immune systems. 

Painting over mould can trap these harmful substances behind the paint, potentially worsening indoor air quality and exacerbating health issues.

Surface Damage

Mould can weaken and deteriorate the surface it grows on, leading to structural damage over time. 

Painting over a mould without addressing the underlying damage can result in poor adhesion and premature paint failure, such as peeling, cracking, or bubbling.

Aesthetic Concerns

Even if the mould is temporarily concealed by paint, it may eventually resurface as the paint deteriorates or moisture levels increase. 

This can result in unsightly stains or discolouration on the painted surface, requiring additional remediation efforts in the future.

Address the Root Cause for a Clean, Healthy Environment

Instead of painting over mould, it's essential to address the underlying cause of the mould growth and properly remediate the affected area. 

This may involve cleaning and disinfecting the surface, repairing any moisture issues or leaks, and applying mould-resistant primer and paint to prevent future growth.
