Mould on the wall | How to remove mould from walls with HG

Mould on walls is a common issue that can damage surfaces, affect furniture, and pose health risks. Effective mould removal requires the right products, as DIY solutions like baking soda, vinegar, and bleach often fall short and lack official approval. HG mould spray offers a quick and reliable solution, visible results in 30 minutes, and is suitable for various surfaces, including tiles and grout. It’s available in spray and foam forms, with the latter reducing odour and splashing.

To prevent mould, ensure adequate ventilation by keeping windows and vents open, or consider installing central mechanical ventilation. While HG's solutions are proven, non-HG methods may not guarantee success. Discover more about maintaining a mould-free environment and safeguard your home’s health.

What's best to avoid when you have to remove mould from a wall?

How to get rid of mould on wallsWhat's best to avoid when you have to remove mould from a wall?
Various tips are shared on the internet. These days, there is strong advice against using these DIY products for mould on the wall.

1. Remove mould with soda
Removing mould with soda is a popular solution. Unfortunately, baking soda does not work on mould.

2. Do not use vinegar to remove mould on the wall
Like baking soda, vinegar does not work on mould either. It is often recommended because vinegar has a low pH value. It has actually never been proven that it removes mould too. Therefore, it is better that you do not use vinegar for mould on the wall.

3. Do not use bleach to remove mould
Bleach is also recommended frequently. However, do not use bleach. As bleach often contains chlorine, it can destroy mould in theory. However, as it has no official approval, the effectiveness of the product on mould has never been tested. Be careful when you use bleach to remove mould from a wall. 
Always use a product with official approval for mould. Like HG's powerful mould cleaners, for example.

Prevent mould on the wall

Prevent mould on the wall. Here are two ways for tackling the cause of mould on the wall.

  1. Ventilate
    Mould in a house is solved with sufficient ventilation. Ventilation is important after cooking, showering or sleeping. Open sufficient ventilation grills and small hopper windows. They may stay open 24 hours a day. Fresh air disappears within 30 minutes, causing damp and dust to accumulate in a home. Opening a window is not enough. Ventilation ensures that damp and dirty air is discharged outside. This decreases the chance of dampness and mould in the home and you create a mould-free home.

  2. Central mechanical ventilation
    Alternatively, you can choose central mechanical ventilation. The used air is extracted from the kitchen, bathroom or the toilet. Fresh air is taken in through the grills in your frames, windows or sliding doors. This decreases the chance of mould in the home and you have clean and healthy walls.
