🏠 How to remove salt deposits (white deposits) on bricks and then treat them for preventive purposes?
White deposits (salts) on bricks appear especially in the fall and spring.
Brick is a kind of hard porous material that perfectly absorbs moisture, which in turn contains various salt impurities.
At a certain temperature, salts naturally “evaporate”, when dried on the surface of the brick, they crystallize and form stains.
White deposits differ in their chemical composition, so the approach to removing them is also different.
Some deposits can be easily washed off with vinegar, water and diluted detergent (it is only useful for removing newly appeared deposits). Long-standing white deposits (salts) may not be removed from the first try even with professional cleaning chemicals.
You can make a solution for washing off the deposits yourself. You will need a two to four percent solution of hydrochloric acid. (Don't forget to stock up on gloves and safety glasses). The second option is simpler: mix a regular detergent and two to three tablespoons of vinegar in a bucket with water. You can also dilute rubbing alcohol in 1 bucket with water. Branded ready-made plaque removers are also sold.
A roller or brush should be used to remove plaque. After a few minutes of applying any solution, rinse it well with water. You can use a stiff-bristled brush and carefully work off the white residue that appears on the brick.
Then the wall should be dried. After that, we can move on to preventing the reappearance of plaque – this is hydrophobization or waterproofing. Simply put, by impregnating the wall, we create a waterproof film. The protective solution can penetrate the brick to a depth of several centimeters and become a kind of armor.
We offer wall hydrophobicizer QIS EMPRENYE.
