Efflorescence is a natural process that occurs, when a fine white powdery substance (Calcium Oxide), exudes to the surface of concrete and clay base material such as bricks. This problem occurs frequently with new precast concrete materials, such as pavers and retaining wall block units used often for steps leading up to building entrances (Fig 2). The easy solution, is to give it time to wash off or apply an efflorescence cleaner such as, RadonSeal Efflorescence Remover www.radonseal.com, which is an easy fix when needed.
