Pavers get their color by adding
pigment to the mix during the
manufacturing process. Colors are very
stable, showing little change over
time. However, as the surface wears
from traffic or weather, there may be
a gradual change in color. It is not
necessary to seal a paver surface. In
some installations, customers prefer
the plain look of the unsealed color.
Sealing your pavers prevents added
dirt from foot and vehicle traffic,
ensures easier surface cleaning,
extends their initial appearance, and
enhances paver color. It may also make
the pavers natural color somewhat
darker as shown at right.
Sand-filled joints may accumulate dirt
with time and traffic. However, some
installations may lose joint sand due
to wind and runoff. In that case,
simply replenish the joints with new
dry sand. If the problem recurs, you
may want to seal the paver surface, or
use a joint sand stabilizer.
Efflorescence is a white residue
caused by lime released from within
the paver. It does not damage the
paver, and generally wears away over
time. If you'd like, efflorescence can
be removed with cleaners made
specifically for pavers. Sealing the
paver surface may also help.
