WINTER DRIVEWAY CARE
Concrete is a very
durable product, however, proper care is required to ensure
longevity. Deicers are harmful especially the first winter. To
avoid surface scaling, discoloration or deterioration; here are
a few tips for your residential concrete surfaces.
DON'T
Use Salt or other Deicers during the First Winter.
Concrete takes approx. 28-56 days ( pending temperature and when
the concrete is placed ) to reach its maximum strength and needs
to be properly cured. While some deicers, such as salt, do not
chemically react with the concrete, they are
"hydroscopic" they attract and maintain the presence
of water and increase the number of freeze/thaw cycles the
concrete must go through. This has the potential of damaging the
surface of the concrete and / or causing discoloration.
DO
Use Sand Anytime.
Sand is the "truly" safe material to use to make the
concrete surface skid resistant is plain sand. This can be
purchased at several locations, frequently at the ready mixed
concrete supplier in your area or local hardware stores. Kitty
litter, while more expensive, is another safe option.
DON'T
Use Deicers With Ammonium Nitrate or Ammonium Sulfate.
These chemicals are often packaged and sold as deicers, but they
will rapidly disintegrate concrete. Common garden fertilizers
containing these two chemicals, or urea, may cause a chemical
reaction which will cause disintegration as well. Pellet
fertilizers should be swept from concrete slabs before
dissolving. Never use fertilizers for deicing purposes. ( *
Always check the labels for ingredients * )
DO
Use a Surface Sealer.
Water repellant coatings and sealers can help prevent damage
from freeze/thaw cycles. These sealers keep water from getting
into the surface pores. They should be applied after the initial
"finishing" & "air drying" period. It
should then be reapplied every two to three years. Deicers which
contain sodium chloride ( common salt ) or calcium chloride may
be used after the first winter IF a surface sealer has been
applied in the fall. Check with your ready mix supplier or
construction accessories supply stores for sealer
recommendations.
At
no time are we, or anyone associated with
exposedaggregateconcrete.com or ACP International implying that
use of salt and deicers are safe or beneficial to concrete. We
understand that in some cases ice melt is required for safety,
and it is for these examples the above guidelines are implemented.
It is our opinion that salt and ice melt are harmful to not only
concrete, but the environment. And should be used sparingly
