Black Mould Growth
We worry about mould growth in the home during winter, when we’ve all got the central heating at maximum to combat the chill.
Mold spore counts are as prevalent in summer as in winter, if not more. Mould spores hitch a ride on pollen grains as they circulate through the air, worsening summer allergies. A research team from the University of Manchester and Manchester University NHS Foundation Trust found that Summer’s lower wind speed and increased temperature caused increased levels of airborne fungal spores.
“Indoor counts were directly correlated to outdoor counts and were elevated in rooms that directly connected to the outdoors, via a window.” said Professor Andrew Jones as part of the Manchester research team.
Worrying news if you were planning on keeping windows and doors open to enjoy the summer sun!
While the exact conditions for mould growth are rarer during the summer, it is still possible. And mould spores can wait. They lie dormant and invisible on the walls of your house until the atmosphere reaches the perfect amount of moisture, air and temperature.
Once the right growth conditions have been met, any mould spores present in the walls will start to grow mould.
Learn how mould grows in the home.
Mould spores in the air can trigger allergies or respiratory issues, particularly for individuals who are sensitive or allergic to mould.
Exposure to mould spores and mycotoxins can lead to symptoms like coughing, sneezing, wheezing, skin irritation, and even more severe health problems in some cases for those with compromised immune systems.
In summer, those who suffer from hay fever (allergic rhinitis) may also find that they are sensitive to mould spores in the air.
To mitigate the threat of mould growth during the summer, it’s essential to control moisture levels and maintain proper ventilation.
Summer weather tends to increase the relative humidity of outside environments, which provides the ideal environment for mould to thrive. Areas with high humidity levels or that lack appropriate ventilation are especially at risk. Condensation can form on windows and walls, creating damp conditions that encourage mould growth.
During the summer, activities like paddling, watering plants, or using air conditioners and cool mist humidifiers can introduce additional moisture into the home. If not properly managed or dried, these moisture sources can contribute to mould growth. Even lightly spraying your face with cool water can add to the moisture content in your home, inching the conditions for mould growth ever closer. As always – bathrooms, kitchens, and basements are particularly susceptible to mould growth due to their exposure to water-related activities.
To keep homes cool, people often seal windows and rely on air conditioning or electric fans. While these can help to maintain a comfortable indoor temperature, they can also trap moisture indoors without sufficient ventilation. Poor air circulation inhibits moisture evaporation and creates an environment conducive to mould growth.
During the summer holiday months, routine home maintenance may be overlooked due to time spent away, outside and just generally taking it easy.
Issues like roof leaks, plumbing leaks, or insufficient insulation must always be dealt with quickly.
Failure to fix these issues all contribute to mould problems later down the line. Prioritising these essential repairs not only ensures a mold-free environment but also safeguards the overall safety and comfort of your home.
Stop mould spores from settling in your home by preemptively applying mould-resistant emulsion paint to your walls. Mould spores cannot survive on walls that have been treated. When winter comes, you won’t be immediately overrun with black mould growth.
Dryzone Mould-Resistant Emulsion Paint is available in Magnolia or White. If you require a different colour to your walls, simply add a mould additive like Dryzone Mould Additive to any type or colour of indoor emulsion paint to give it robust mould-resistant properties.
Whether you use Mould-Resistant Emulsion Paint or Mould Additive, the anti-mould component is active for up to 5 years – keeping mould away for a long-lasting solution that requires little to no maintenance assuming the wall is kept in good condition.
Be vigilant. Here are the things that influence mould growth all year round, even in the summer.
