Pavers with Efflorescence Cleaned Pavers What is the whitish deposit I see on some paver installations?
You are probably referring to efflorescence, a natural and common occurrence in concrete and brick products. Efflorescence is the result of salts in the materials used in production migrating to the surface of the pavers. This is not a defect or harmful to the pavers and will usually weather away with time. If you don’t want to wait for it to weather away, Techni-Seal offers an excellent cleaning product to remove it (see page 39). Once the pavers are cleaned it is recommended that they be sealed.
