How to get rid of mold on the wall?


Unsightly stains on the wall, typical smell and above all countless health risks. We’re talking, of course, about the mould that can plague your house, apartment and garage. Find out with us why it bothers us at home and how to get rid of mould on the wall once and for all.

Where does mould come from and where is it most common?

There are many types of mould, so it’s not surprising that they are subtly found all around us. And once mould and its spores reach our homes, all they need to survive is the ideal conditions we often unwittingly provide for mould.

Most often, it’s higher humidity, poor furniture placement or inadequate ventilation. We may then notice unsightly black or coloured patches and white clumps, which are most often found in the corners of a room, by windows and doors or over large areas. Although the most common problem is mould on walls, it can also take hold on wood, plastic or glass.

Mould prevention is essential

As with a number of problems, prevention should be the mainstay for tackling mould. Whether we have just moved into a new home or have managed to remove all the mould.

  • Choose a suitable coating that prevents condensation in the exterior masonry.
  • Brighten the interior and allow the sun’s rays to visit regularly – you don’t have to demolish straight away, just limit the use of curtains or blinds during the day.
  • Ventilate regularly and effectively. Several times a day for at least 3-4 minutes open a window wide open in every room, a fan alone will not take care of air exchange this way.
  • If the humidity in a room is really high (e.g. bathrooms, rooms with aquariums and lots of flowers), get an effective humidity absorber with a replaceable filter.
  • Move furniture into the space and don’t let the walls breathe. Leave at least a 5cm gap between larger cupboards or other spacious furniture and the wall.
  • Don’t overheat. You don’t like high temperatures at home either, and you’re helping the aforementioned condensation.
  • Don’t create additional unnecessary moisture.  When cooking use a cooker hood, hang your laundry outside if possible or get a dryer.

So how do you get rid of mould on the wall?

If you’re reading this article right now, it’s obvious that you’re struggling with mould and old wives’ advice isn’t enough in your case. So let’s take a look at how to properly remove mold from a wall.

1) Dry the walls

If the walls remain damp or wet, even a fungicidal coating won’t help. So you need to address the cause and then dry the walls, for example with a properly directed direct-fired heater. However, to avoid inhaling the agitated spores, mechanical removal of the mould is ideal.

2) Mechanical mould removal from walls

This is certainly the most effective procedure. So, if possible, put on your protective gear and respirator and get to work. First spray the masonry with a disinfectant to keep spores from flying through the air, then remove the paint and any affected plaster.

Then treat the area again with a disinfectant or fungicide and allow it to dry thoroughly before repairing. If it is a mould-prone area, choose a thermoplastic or fungicidal paint to paint over it.

3) Fight mould on the wall with chemistry

If the area affected by mould is really small, chemicals can help. On the market, we can find chlorine-based products, which include, of course, the well-known Savo anti-mould. It can destroy the mould on the eye and bleach the substrate beautifully, but if a deeper layer is affected, it can hardly cope with it and the problem will occur again in time. So definitely don’t expect miracles after the first application and focus on eliminating the cause.

Fungicides are another possible option. They are not as effective and will not bleach the substrate, but the chlorine in your home will not irritate you.

Fungicidal products are actually a type of chlorine-free products that do not bleach the surface, but can quickly fight mould thanks to fungicidal ingredients and also serve as an effective prevention.

4) Anti-mould fungus on walls

You certainly know that mold belongs to the group of fungi. And the novelty of the past years is just a clever non-toxic fungus that is not harmful and can rid you of mold permanently. It parasitises classic mould and, thanks to its invasion, can also eradicate mould under plaster or in deeper layers of masonry.

5) Professional intervention

Have you tried almost everything without success? Or is the affected area so large that you don’t dare to intervene yourself? Modern companies have several effective ways up their sleeve, and they certainly won’t just run to you with a bottle of Sava. On the contrary, they will carry out a thorough investigation and diagnosis of the mould, recommend the necessary treatments or can rid you of the mould using ozone cleaning or other remediation methods – from special coatings to masonry work.

Wall mould advice

Even previous generations have struggled with damp and pesky mould. So, leaving aside the precautionary advice around ventilation and heating mentioned above, here are a few granny tricks for fighting mould:

Baking soda is absolutely essential in the home. A 1:1 solution of baking soda with water can be used to rub or spray the affected area.

Quenched lime is more of a solution for basements or garages, but it’s proven over the years.

Lemon or grapefruit will also help, again in the form of a spray, you can use fresh juice or concentrate.

Vinegar is another great fighter, it may make your home smell bad for a while, but the result is said to be worth it.
