Have you noticed whitish marks on the walls of your basement or ground level? You most likely discovered saltpeter, deposits made of mineral salt that form when potassium nitrate found in building materials used in your home come into contact with oxygen and excess moisture.
Find out more about this visible efflorescence and treatment solutions for saltpeter on your walls, as well as methods for avoiding its appearance.
Saltpeter on walls: why should it be treated?
The appearance of whitish spots on concrete walls is more than a simple cosmetic problem. This can also be a problem for your personal well-being and the good condition of your home.
Indeed, there are numerous risks associated with this deposit’s presence. Since its appearance comes from excessive moisture in the foundations, this defect could, among other things, be hiding mold or fungi. Not to mention an increased proliferation of dust mites that can lead to allergies and other respiratory problems.
In addition to health risks, saltpeter can have a negative impact on most house materials and can cause paints and plasters on your walls to crumble.
Repair cracks in foundations and walls
A first step in treating saltpeter is to check for cracks in walls and foundations. The goal is to avoid entry points that allow moisture to infiltrate the walls. If you notice any suspicious cracks, call a professional. An expert can perform an in-depth crack inspection, and therefore determine the severity of the issue.
Waterproof your home
In addition to repairing any cracks, it can be useful and even necessary to have them waterproofed. Essentially, if your home is old or weather events hit your foundations, for example, moisture can enter much more easily. When you hire an expert to assess your situation, they can recommend solutions that are adapted to your specific case such as the installation of a waterproofing membrane on your exterior foundations.
Treat saltpeter before disaster strikes
As you can see, you should never leave a saltpeter problem untreated since it can endanger your home and your health, as well as hide other problems. Assessing the condition of your home, including cracks on walls and floors, and the rate of moisture infiltration is the best method for permanently getting rid of saltpeter. Unlike surface treatments that will only postpone the issue.
