Can You Paint Over Mould

Mould is a scourge that every household and occupied building must eradicate. Unfortunately, some people may not know the right way to prevent or get rid of mould. But does painting over it remove it? Or make it worse?

In this blog, we will answer the question ‘Can you paint over mould?’

With new buildings being made to be as energy efficient as possible, and the UK aiming for 95% of its electricity usage to be low carbon by 2030, it is imperative to understand how we can make the most of our ventilation. This is where ventilation units come in.

To prevent mould, fresh air should constantly be introduced into your dwelling daily, as it helps to regulate temperature and reduce condensation. Introducing fresh air can be as simple as having a ventilation routine, or installing extractors or MVHR units. Almost all of this is facilitated by ducting.

At I-Sells, all things ventilation and ducting related is our speciality, and we are here to answer the questions we know are common for those new to HVAC and what it encompasses.

Where are mould hotspots in a house?

Mould thrives in damp, dark, and organic environments. Bathrooms are prime targets due to constant exposure to shower spray, sink splashes, and toilet use. Poor ventilation in bathrooms traps moisture, creating a breeding ground for mould.

Kitchens are another danger zone, with moisture accumulating around sinks, dishwashers, and refrigerators. Leaky pipes under these appliances can go unnoticed for long periods. Laundry rooms see their fair share of moisture from damp laundry and condensation from dryers.

Exterior walls, especially those facing the outdoors, are susceptible to condensation, particularly in cold weather. Corners and window areas are especially prone because they tend to be colder than other parts of the wall.

Windows themselves can become breeding grounds for mould thanks to condensation build-up, especially in rooms with high humidity. Basements can be naturally damp and poorly ventilated, making them mould magnets if not properly maintained.

Attics can harbour mould due to poor ventilation or roof leaks. Moisture can build up and cause mould to grow on insulation, beams, or even stored items. Don’t forget about the areas around pipes. Leaks behind walls, under floors, can introduce moisture that promotes mould growth even if it’s not visible at first.

Even carpets and rugs can also become mouldy if spills, pet accidents, or dampness from basements aren’t addressed promptly and allowed to dry out completely.

Other areas mould can grow

Closets, cabinets, and pantries lacking proper airflow can trap moisture, creating a mould-friendly environment. The type of building materials you have can also play a role. Porous materials like drywall, wood, and fabric can absorb moisture and become susceptible to mould growth if not maintained properly.

Remember, even areas that seem dry can harbour mould if they were previously exposed to moisture and haven’t dried out completely. Be sure to stay vigilant and check these high-risk areas for signs of mould growth.

Is mould always caused by poor ventilation?
