How to Apply Anti-fungal Paint Like a Pro

Aug 03, 2023Richard Weager

Anti-fungal paint is a special type of paint formulated with substances that inhibit the growth of mould, mildew, and other fungi. It is particularly useful in areas prone to dampness and high humidity, such as bathrooms, kitchens, and basements, where fungal growth is a common problem.

How Does Anti-Fungal Paint Work?

Anti-fungal paint works by creating an environment that is unfavourable for the growth of fungi. It contains active ingredients that repel, prevent, and kill fungal spores, thus protecting the surface from fungal contamination. When applied to a surface, it forms a protective layer that prevents the adhesion and growth of these fungi.

Why Use Anti-fungal Paint?

Anti-fungal paint is an excellent choice for preserving the aesthetics and longevity of your home. Fungal growth can cause discoloration and degradation of surfaces. More importantly, it can result in poor indoor air quality, causing health issues such as allergies and respiratory problems. Therefore, using anti-fungal paint can improve not only your home’s appearance but also its indoor air quality.

The Natural Approach to Anti-Fungal Paint

Benefits of Natural Anti-fungal Paint

Natural anti-fungal paint is formulated with non-toxic, eco-friendly substances that deter fungal growth. Unlike conventional anti-fungal paints, which may contain harmful chemicals, natural anti-fungal paint is a healthier choice for your home and the environment. Additionally, it often has less of an odour and is easier to clean up.

Key Ingredients in Natural Anti-fungal Paint

Natural anti-fungal paint typically includes ingredients like essential oils, minerals, and plant extracts that have anti-fungal properties. For example, oils from tea tree, thyme, and neem are known for their anti-fungal effects. Some paints may also use mineral-based compounds like lime, silicate, zinc and copper, which are effective at inhibiting fungal growth.

Addressing Environmental Concerns with Natural Anti-fungal Paint

Environmental sustainability is a significant concern for many consumers. Natural anti-fungal paint is a responsible choice, as it minimises the release of harmful volatile organic compounds (VOCs) into the air, contributing to better air quality. The use of renewable, plant-based ingredients also reduces reliance on fossil fuels and the resulting carbon emissions.

Preparing for Your Paint Job

Assessing the Area for Mould and Fungus

Before painting, thoroughly inspect the area for any existing mould or fungus. If you find any, it’s crucial to clean and treat the area first to prevent further growth underneath the new paint. This may involve using a mould removal product or a solution of bleach and water.

Tools and Materials Needed

The basic tools you’ll need for your painting job include paint brushes or rollers, a paint tray, a stir stick, masking tape, drop cloths to protect your flooring, and, of course, your anti-fungal paint. It’s also a good idea to have some rags for clean-up and a ladder if you’ll be painting high areas.

Safety Precautions When Using Anti-fungal Paint

Even when using natural anti-fungal paint, safety should always come first. Make sure your work area is well-ventilated to avoid inhaling paint fumes. Wear protective clothing, including gloves and safety glasses. Lastly, keep paint out of the reach of children and pets.

Getting Your Surface Ready

Cleaning the Surface

Start by ensuring that your surface is free from dirt and debris. Clean the surface thoroughly with warm water and a mild detergent. If any mould or mildew is present, use a specialised cleaning solution to eliminate it, ensuring to follow the product’s instructions carefully.

Repairing and Priming the Surface

Once your surface is clean, inspect it for any damage, such as cracks or chips. Repair these with a natural surface filler, and then sand the surface to create a smooth finish. If your surface is very porous or you’re painting over a dark colour, applying a layer of primer can be beneficial. A primer not only provides an additional layer of protection against mould and mildew, but it also gives your anti-fungal paint a better surface to adhere to.

Applying Your Anti-Fungal Paint

Mixing Your Paint

Before you begin painting, stir your anti-fungal paint thoroughly to ensure all the components are well mixed. If the paint has been sitting for a while, the anti-fungal agents may have separated from the rest of the mixture.

The Correct Technique for Applying Anti-fungal Paint

Start by using a brush to cut around the edges of your surface. Then, use a roller to fill in the middle sections. Aim for long, even strokes, maintaining a wet edge to avoid streaks or patches. It’s typically recommended to apply at least two coats of anti-fungal paint to ensure optimal protection.

Ensuring a Smooth and Even Coat

To achieve a smooth, even coat, avoid overloading your brush or roller with paint. Additionally, be sure to wait until the first coat is completely dry before applying a second. This allows for the best coverage and ensures the anti-fungal agents are effectively dispersed.

Drying and Aftercare

How Long to Let Anti-fungal Paint Dry

The drying time for anti-fungal paint can vary based on the brand and environmental conditions, so it’s always best to check the manufacturer’s instructions. However, on average, you should allow at least 24 hours between coats and before the painted surface is touched or exposed to moisture.

Proper Ventilation During and After Painting

Ensure the area is well ventilated while you’re painting and during the drying process. This aids in the drying process and helps disperse any fumes from the paint.

Long-term Maintenance and Care for Anti-fungal Paint Surfaces

Maintaining your newly painted surface involves regular cleaning to prevent dirt and dust build-up, which could potentially harbour mould or mildew. Moreover, even though anti-fungal paint is designed to resist fungal growth, it’s important to manage moisture levels in your home since high humidity can still encourage mould and mildew.


By now, you should be well-versed in the process of preparing, applying, and maintaining anti-fungal paint. Remember the importance of a clean, repaired, and primed surface; the right painting technique; and the need for proper drying and ventilation.

Embrace the satisfaction that comes from not only completing a DIY project but also knowing that you’ve taken steps to improve the health and safety of your home environment.

Applying natural anti-fungal paint is an excellent step towards creating a healthier home. By choosing natural products, you’re reducing exposure to harmful chemicals while still protecting your home from mould and mildew.
