How to Get Rid of the White Cloudiness on Pavers

The surfaces of pavers often develop a white cloudiness, called efflorescence, soon after they are installed. The white film seen on such stones is actually calcium carbonate, which is a byproduct of the reaction when cement is exposed to the environment. Efflorescence is often considered unsightly to many homeowners, but the problem is strictly cosmetic and does not impair the functioning of the pavers. Most pavers develop this cloudy appearance within three to six weeks after being installed. The cloudiness gradually fades, and after three to six months, the effervescence of the pavers is likely to have completely disappeared. Although the problem is likely to solve itself in time, there are ways to speed up the process.
