Does Antimicrobial Paint Prevent Mould

According to the UK Health Security Agency, approximately 2 million people currently live in homes with significant damp and/or mould, affecting 3-4% of residences across England. There are ways to combat this issue with household products, but regular cleaning practices are rarely effective in severe scenarios. Antimicrobial paints, while not a sole solution, effectively compliment a broader strategy to prevent and protect spaces that might be prone to developing mould.


Understanding Mould Growth

Mould grows in environments with excess moisture and poor ventilation. In bathrooms, for example, condensation forms when water-vapoured saturated air gets in contact with cooler surfaces, such as windows or walls. Over time, this condensation penetrates porous surfaces, creating damp patches that increase mould growth. Regular cleaning, ventilation and dehumidifiers might offer temporary relief but without addressing the moisture problem, mould will likely increase.

What Are Antimicrobial Paints?

What Are Antimicrobial Paints

Antimicrobial paints are specially designed to help prevent mould growth. Generally thicker than standard paints and often oil-based, they create a barrier that prevents moisture from seeping into surfaces. These paints contain antimicrobial agents that inhibit the growth of various microorganisms, including mould, by disrupting them on a cellular level. Higher concentrations of antimicrobial agents in paint can create a product that is particularly effective against mould growth.

  • Moisture Barrier: The thickness and oil base of antimicrobial paint create a barrier that stops condensation from penetrating the surface, which results in preventing damp patches.

  • Chemical Protection: These paints contain antimicrobial agents that inhibit the growth of mould and bacteria by affecting their cell structures.

Do Antimicrobial Paints Work?

Do Antimicrobial Paints Work

Antimicrobial paints are designed to significantly slow down the growth of mould , providing a long-lasting protective barrier. These paints help to prevent moisture from penetrating the walls, thus reducing one of the primary conditions for mould growth. However, it is important to note that environmental factors can still cause condensation on the surface, which can provide a habitat for mould spores.

For optimal effectiveness, proper application and regular maintenance of the treated surfaces are essential. Regular cleaning prevents the accumulation of dirt and dust, which can otherwise create favourable conditions for mould. When applied and maintained correctly, antimicrobial paints offer a robust defence against mould growth, ensuring enhanced protection an hygiene for several years.


Biocote Efficacy

To prove the effectiveness and longevity of antimicrobial paints treated with BioCote® additives, samples underwent testing in an independent laboratory. These samples were aged to simulate 40 years of product aging.

The testing revealed that BioCote® additives reduced the presence of bacteria on treated surfaces by 99.99%, demonstrating the efficacy of BioCote® antimicrobial agents. These results stress the ability to offer long-lasting protection against mould growth when used in antimicrobial paints.

While anti-mould paints offer a practical short-term solution to mould problems, they are not a standalone fix. Improving your home’s ventilation and reducing humidity levels are among the most effective ways to prevent mould from recurring. By combining these strategies and using effective paints enhanced with BioCote® antimicrobial technology, you can create a mould-free living environment.
