Does the wall at your home look like this?
Paver Sealing Vegas now offers a solution to help fix and maintain your cinder block walls around your home. We begin by power washing the wall to remove dirt and dust and treat the white areas, commonly referred to as Efflorescence which is very common in our area. According to the “ICPI” (Interlocking Concrete Pavement Institute), efflorescence is a natural process, in which a random white haze may appear on the surface of the brick, which is caused by lime or a water soluble calcium oxide that rises to the surface after repeated saturations due to rain or sprinklers. Efflorescence does not affect the integrity of the bricks and will usually resolve itself with time and exposure to the elements.”)
The proper coating on concrete brick pavers can either retard or stop completely the efflorescence process due to the moisture protection achieved by the sealing process. However, this warranty does not state or imply that efflorescence will stop as a result of this process.
In addition, oil based sealers will actually prevent the efflorescence from rising to the surface of the brick paver and get trapped under the sealer. The only fix for this is to strip the pavers of all sealer using a solvent or stripper to remove the sealer completely. Water based sealers, such as Seal n Lock are a "breathe-able" product, meaning that the efflorescence can escape through the sealer and be simply washed away with a garden hose.
On new walls, we offer a sealer that uses a siloxane water repellent that is designed to weatherproof old and new concrete and masonry surfaces against natures destructive forces. It provides a long lasting breathable barrier that resists cracking, airborne dust and dirt, salt, efflorescence, and spalling.
