How to fight against wall humidity effectively

Humidity on walls is a common problem in homes. It can come from several causes: capillary upwelling, water infiltration or condensation of water vapor.
Before acting, it is essential to identify the origin of the problem in order to adopt the right solution.

Identifying the cause of wall humidity

To effectively treat humidity, a distinction must be made between:

• Les Capillary lifts : water from the ground rises through the walls due to poor sealing.
  
  
• Les water infiltrations : often due to a crack, a leak or a porous wall.
  
  
• La condensing : forms when hot, humid air meets a cold wall, causing water droplets to form.
  
  

👉 In the first two cases, it is recommended to call in a building professional to repair and sanitize the walls.

👉 If the cause is condensation, simple actions are often enough to reduce humidity.

Ventilate to reduce condensation

Ventilation is the first step in fighting condensation.
It makes it possible to homogenize the water vapor in the air and to prevent it from being deposited on the walls.

Think about:

• Open windows regularly (even for a few minutes a day).
  
  
• Maintain the VMC or install an air extractor in humid rooms.
  
  
• Ventilate closets and poorly ventilated areas.
  
  

Heat the room properly

Progressive heating prevents the creation of cold spots on the walls.
You have two options:

• Heat slowly, so that the walls heat up at the same rate as the ambient air.
  
  
• Use a precise temperature setpoint to maintain a homogeneous temperature and avoid condensation.
  
  

Tip: use a humidity tester or sensor to monitor the evolution of the relative humidity level in the room.

Use dehumidifying products

Dehumidifying products are an effective aid in absorbing excess water vapor in the air.

Depending on your needs, you can use:

• Of moisture absorbers based on salts (such as calcium chloride).
• Dehumidifier bags in small spaces.
• An electric dehumidifier for areas with high humidity.
• Use the Product: So Sponge AS-C tape, without maintenance or electricity and 3-year warranty.

These solutions make it possible to maintain a stable relative humidity, thus limiting the risks of condensation on the walls.

In summary

To combat wall humidity, you need:

1. Identify the cause (rises, infiltrations, condensation).
   
   
2. Ventilate rooms effectively.
   
   
3. Heat evenly.
   
   
4. Use suitable anti-humidity products.
   
   

Good air and temperature management is the key to maintaining your walls and your comfort on a daily basis.
