Efflorescence is the white, chalky residue that forms on
the surface of concrete brick pavers. Efflorescence is
completely natural and occurs with all concrete products
containing cement. Efflorescence is created when the
calcium oxide naturally found in the cement mixes with
water to form calcium hydroxide and then is leached to
the surface of the paver where it comes in contact with
the carbon dioxide in the air and then forms calcium
carbonate which forms the white, chalky residue
referred to as efflorescence.
The formation of efflorescence is NOT a sign of defective
or damaged concrete brick pavers.
Efflorescence will naturally disappear on its own once all of the calcium oxide in the cement is leached out, but the time that this takes varies upon your local climate conditions. The more rain that your concrete brick pavers receive, the faster the efflorescence will leach out.
White Mountain Efflorescence Remover is specially formulated
for removing efflorescence from concrete brick pavers and
can be applied using a low pressure sprayer, brush, or
watering can. Extreme cases of efflorescence may require a
