How are white patches formed on paving stones?
Even on the best quality product, sometimeswhite blooms may appear , which keep the owners awake at night and spoil the appearance of the carefully arranged paving surface. Their appearance is not affected by the way in which the paving stones were laid.
-The white coating on the surface of the cobblestonesis nothing else than limestone sediment, which is a natural phenomenon and is not dangerous for the durability of the cobblestone structure. It is formed as a result of concrete stabilization and hardening in response to changing weather conditions.This is because almost every cement from which paving stones are made contains calcium compounds that react with moisture coming from atmospheric precipitation - explains Kamil Drewczyński, an expert at Libet.
It also happens that white raid occurs maybe as a result of an incorrectly made substructure for paving stones. In both casesthe white coating on the paving stonesis not dangerous for the pavement.

Worth remembering!White blooms on paving stones are a natural phenomenon and usually disappear on their own within 1-3 years. They naturally disappear faster on unroofed surfaces, which is facilitated by rinsing out by rains. Possible removal of white efflorescence from paving stones makes sense mainly on roofed surfaces.
We can approach the removal of white blooms on cobblestonesin several ways, e.g. by washing the entire surface with a pressure washer. The second solution is sandblasting or grinding the surfaces of individual elements. The first method, however, is quite laborious and ineffective, while the second carries the risk of damaging the ankle structure!
- If we decide toremove limestone sediments from paving stones , the most advisable method is the chemical method with the use of specialized preparations.For leaching, because we are talking about it, a low-percentage solution of acetic, hydrochloric or formic acid is usually used - suggests our expert Kamil Drewczyński.
