How Does Mould Form?

Mould is a common problem in homes and buildings, and it can cause a range of health problems if left untreated. But have you ever wondered how mould actually forms in the first place? In this post, we'll take a closer look at the science behind mould growth and explore the factors that contribute to its formation.

Mould is a type of fungus that grows in damp and humid conditions. It reproduces by releasing tiny spores into the air, which can then settle on surfaces and begin to grow under the right conditions. Mould spores are present everywhere, both indoors and outdoors, and they are a natural part of the environment. However, they can become a problem when they start to grow in large quantities indoors.

So, what are the conditions that mould needs to grow? There are three main factors that contribute to mould formation: moisture, a food source, and the right temperature range.

Moisture: Mould thrives in damp and humid conditions, which is why it's often found in areas like bathrooms, kitchens, and basements. Moisture can come from many sources, including leaks, condensation, and high humidity levels. Mould can start to grow in as little as 24-48 hours after exposure to moisture, so it's important to address any water damage or leaks as soon as possible.

Food source: Mould needs a food source to grow, and it can feed on a variety of organic materials such as wood, paper, fabric, and even dust. In homes, mould is often found on surfaces like Gyprock, carpeting, and insulation. Regular cleaning and maintenance can help reduce the amount of organic material in your home, which can help prevent mould growth.

Temperature: Mold thrives in a temperature range of 15-26°C, which is why it's more common in warmer climates. However, mould can still grow in cooler temperatures if the other conditions are right. In fact, some types of mould can even grow in temperatures as low as 0°C.

Once mould has formed, it can spread quickly and release spores into the air, which can cause health problems like allergies and respiratory issues. It's important to address mould growth as soon as possible to prevent it from spreading and causing further damage.

In summary, mould forms in damp and humid conditions where there is a food source and the right temperature range. If you suspect mould growth in your home, it's important to address the underlying moisture issue and take steps to prevent it from returning.
