Will it go away?
The white substance that appears on pavers is called efflorescence and is caused by calcium hydroxide, a naturally occurring phenomenon in all masonry products. These salts and minerals wick from pavers, deposting a white film on the surface, which will, in time, disappear, or it can be removed with a mild cleaning solution. We carry efflorescence remover for cleaning purposes. Efflorescence in no way affects the structural integrity of the pavers.
