Efflorescence is a natural formation that may appear on any concrete or masonry product. It is actually the residue of soluble salts carried to the surface by moisture – a natural by-product of the chemical reaction between cement and water. Efflorescence does not affect the structural integrity and will dissipate over time. It is not indicative of a flawed product. If desired, it can be removed using EF Efflorescence Remover or PW Paver Wash.
No negative effects on the asphalt driveway should be expected. But it is possible that the surfactant could have a slight impact on the tar and dull it out. Test in a small discrete area if you are concerned.
EF Efflorescence cleaner is a mild acid used to remove the efflorescence currently visible. The cleaner alone will not prevent future blooms of efflorescence from occurring. To help prevent efflorescence blooms in the future, please consider the use of a penetrating sealer to waterproof the surface.
