Efflorescence Removal from Brick Pavers
IF you have white, chalky looking brick pavers, we can help with our efflorescence removal treatment during the cleaning and sealing process. We use Seal ‘n Lock brand Efflorescence Remover, which removes the efflorescence from the surface of the pavers, and also helps lift out additional efflorescence from inside the brick paver. Read below to learn more about efflorescence in brick pavers.
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 sealing of 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 the sealing 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.
