How does efflorescence relate to applying sealer?
Most sealer manufacturers recommend that you wait six weeks to six months after the installation of new pavers to apply their product. This is done to allow time for the majority of the efflorescence to come out of the stone. If it this is not done, the whitening can become trapped between the top of the stone and the seal coat, “locking in” the efflorescence. If this happens, the only way to remove the efflorescence is to remove the sealer, clean the efflorescence and reseal the surface.
