How to remove mould from walls?

Mould on walls can appear in a spot where there is a great deal of humidity. It can be rooms like bathrooms, kitchens, boiler rooms as well as those ones where we wouldn’t expect any mould risk, living rooms and bedroom, for example.

Unfortunately, it is possible as a result of negligence, construction fault or a flow of time, occur so called thermal bridges in the building. These are junctions where insulation is not continuous and causes heat loss. The wall temperature decreases and condensation temperature is exceeded. Consequently, rooms such as living rooms or bedrooms can suffer from humidity on the walls and in the long run, mould.

If it occurs, it is necessary to take reasonable actions and remove it as soon as possible, since apart from aesthetical values it is also dangerous for our health.  Moulds, which can develop in our houses, are pathogenic and toxic spices which in favourable conditions consist of large colonies, being one of the biggest sources of air contamination, which contribute to various illnesses and allergies.

3 effective steps of removing mould

Step 1 – determining and removing reasons of occurrence.

Determining plays a crucial role therefore it’s worth getting to know all possible reasons of mould formation. One of them can be for example, improper ventilation (condensing moisture). It’s necessary then to ventilate the room frequently, install window or wall ventilators or even mechanical ventilation. There is also an option to dry the premises by using electric air driers.

Mould can be an effect of numerous flooding resulting in roof leakiness or faulty installations as well as humidity seeping from the ground due to inappropriate insulation (capillary condensation),as well as previously mentioned thermal bridges. Correctly establishment of mould formation and effective removal is the most important step as far as getting rid of mould on walls is concerned.


Step 2 – mould removal.

Depending on how deep the mould is, its removal might be either simpler or more difficult. Early detected moulds which were the result of air humidity within the room can be removed by using a scrubbing brush or a sponge, by dry-clean method or water with detergents. In the event of paint peeling it must be removed as well.

After the spots are cleaned it’s necessary to paint them by applying several coatings of antifungal agents. Modern chemical agents allow us to remove efflorescence successfully, however, it’s necessary to be extremely careful when applying them since they are hazardous materials.

After thorough surface protection by applying antifungal agents and the new plaster, the spot must be painted.



In order to minimize the likelihood of mould reoccurrence it’s necessary to use a proper paint. Sniezka Kitchen – Bathroom is a biostatic paint which can be applied onto the aforementioned surfaces. Thanks to innovative technology – SILVER FORMULA – it allows to eliminate excessive amount of pathogenic (i.e. developing diseases) bacteria and moulds. By taking advantage of pure silver the paint has biocidal properties which were examined in laboratory tests during research conducted by POCH S.A. in Gliwice as far as antibacterial, antifungal and anti-yeast properties are concerned.

Carrying out the removal actions of mould mentioned above as well as eliminating the reasons of its formation and proper surface protection by applying antifungal agents and paint, allow us to get rid of the problem successfully.
