How Long Does Anti Mould Paint Last?

With many mould prevention options designed to help you not have to deal with the issue of mould, anti mould paint is an effective tool used to help homeowners and building occupants alike.

In this blog, we will be answering the question ‘How long does anti mould paint last?’

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 PIV systems. Almost all of this is facilitated by ducting.

I-Sells is here to provide the answers you need whilst also supplying you with all the information you need to combat mould and have a well-ventilated home.

A basic explanation of mould

Mould, otherwise known as damp, is a fungus that grows on wet surfaces. Mould comes in a variety of colours: Black, Green, Brown, Grey and White. It can be difficult to identify mould by colour as it can occur in many shades. Some of the most common mould strains in the home are:

  • Black Mould – Also called Stachybotrys chartarum, Black mould is commonly found in bathrooms and wet rooms but can also occur on cold exterior walls in habitable rooms such as the bedroom or living room.
  • Cladosporium – Commonly found in bathrooms, under sinks, and around faucets but it can grow on surfaces like carpets, furniture, walls, and floors.

Mould reproduces from tiny spores. The spores float through the air and deposit on the surfaces. Under adequate temperature, moisture, and nutrient conditions, the spores can form new mould colonies.

If you have found mould in your home, you need to assess if this is your landlord’s responsibility (for example it could be from a leaking roof that needs repairing). Or if the dampness is caused by improper ventilation. To assess your options, click here.

Symptoms of mould exposure

Symptoms of mould exposure

Mould can severely affect your immune and respiratory system, as the spores are easily breathable and not obvious to see through the human eye. Having a mould allergy, or prolonged exposure to mould will result in you displaying the following symptoms when exposed to mouldy environments.

  • Dry, scaly skin
  • Nasal congestion
  • A cough
  • Watery eyes
  • A weakened immune system

Everyone’s symptoms may vary, but if you’re in an environment with mould and experience these symptoms, try your best to remove the mould as soon as possible.

Can any house develop mould?

Yes, any house, or building has the potential to develop mould if the area is left without any ventilation treatment and sealing of cracks and holes.

You should never overlook the danger of mould. A tiny amount can develop into a large patch if it is not addressed, it will not only damage your home but your health too. Mould-proofing your house should always be done, always remove any mould as soon as you possibly can.

What is anti mould paint? How does it work?

As the name suggests, anti mould paint, is a paint that can be used for walls and ceilings, it contains special properties that make it resistant to mould. The anti-fungal properties of the paint ensure that mould doesn’t grow on it.

There are different brands of anti mould paint, all of which may have their own unique properties, but for the most part, anti mould paint is not to be used as a mould remover. You must remove the mould before applying this paint, this paint is made specifically for the prevention of mould, not removal.

How long does anti mould paint last?

Our Kair anti mould paint lasts for 5 years, providing protection against black mould on walls and ceilings. This doesn’t mean that the paint will peel away in 5 years, or that the mould will instantly appear after the 5-year countdown is over.

The likelihood is, after 5 years the antifungal properties in the paint may have expired. What this means is if your home is still an environment where mould can thrive, it will re-appear after some time, leading you to start the removal and painting process again.

Alternatively, if you used the 5 years to create an inhospitable environment for mould, supplemented with a ventilation routine, the mould may not return.
