What is efflorescence?
Efflorescence is a whitish powder-like deposit that can form on the surface of natural building materials like pavers. As water evaporates from the stone, it brings calcium hydroxide to the surface. When calcium hydroxide meets carbon dioxide in the air, a reaction occurs forming calcium carbonate. This is what is known as efflorescence.
Efflorescence is a whitish powdery residue that attaches itself to the surface of brick pavers. Putting pavers over a new concrete base increases the chances of efflorescence because the new concrete is loaded with lime and other minerals that can be drawn through the paver to the surface. There are cleaners made to remove efflorescence.
Efflorescence is a naturally occurring phenomenon that causes a white lime deposit on the face of any concrete product. It has to do with leaching of salts out of the concrete matrix and depositing on the surface when the water evaporates. It is not considered a defect of the material. It has no adverse effect on the physical structure of the product, and will normally wear away naturally within a few days or weeks. It can be cleaned off with a number of commercial cleaners. It should not be confused with hard water stains, although both may require the same weathering or cleaning to eliminate.
It is a whitish powder-like deposit which sometimes appears on concrete or clay products. The deposit is the residue of a soluble salt carried to the face of the product by moisture and left on the surface as a dry powder following evaporation of the moisture. Efflorescence does not affect the integrity of the pavers.
There is a chance that after a few weeks or months pass after installation of paving stones, a white hase may appear on the surface of the pavers. This is known as efflorescence. There’s no reason to be concerned that your pavers are damaged or defective. The concrete pavers are experiencing a natural process that all cement-based products may experience. Hessit Works put chemical additives in the concrete to reduce the likelihood of efflorescence.
