Care: Frequently Asked Questions & Answers
Do I really need to seal my type of concrete?
Aggregate Concrete is designed to be sealed, usually with
a high gloss sealant to create that "Wet Look". One of the
reasons it must be sealed is because of the open pore design
of the surface that if left un-sealed, water and contaminants
to can easily enter the concrete and cause damage from freeze/thaw
cycles (as well as staining the concrete). Stamped concrete
is also designed to be sealed and like all designed concrete
will require maintenance to protect it's finish.
colour coat is extremely thin, be very careful not to do
irreparable damage with a pressure washer.
So what about all the other types of concrete?
makes sense to maintain your concrete and avoid the substantial
expense and hassle of replacing it after it becomes damaged.
For concrete, sealing is a good preventative action to help
prevent stains and damage from freeze/thaw cycles as well
as environmental hazards.
types of concrete can be sealed with several different types
of sealant to choose from. Even the mostly overlooked garage
floor is a great candidate for protection. Your
garage floor takes most of the punishment during winter
months because your car drops salt and debris collected
from the road and deposits it on the concrete where it attacks
the surface often resulting in pitting, chalking, and flaking.
If you own a vehicle that leaks oil you know how hard it
is to clean off the oil after a winter of leaking, even
with a good pressure washer.
popular type of finish for garage floors is epoxy based
products that come with a very long service life and are
available in many colours. Epoxy based sealants can also
be installed with a grip surface to dramatically improve
traction when wet. This type of finish is resistant to all
oils, battery acid, brake fluids and of course salt.
Crackman also sells and installs all types of chemical resistant
laminates on garage floors. There are all types of great
patterns to choose from that can really make your garage
a showcase area for your prized vehicles.
How do I care for my concrete in Winter?
can help maintain concrete by shoveling the snow from your
driveway, sidewalk and steps. By keeping the snow cleared,
these is less chance that it will compact down - eventually
freezing into the surface that accelerates the freeze/thaw
cycle. The less number of times that water enters concrete
and freezes, the less likely that it will become damaged.
a plastic shovel instead of a metal one. Bent/sharp corners
of a worn metal shovel can damage the surface of certain
types of concrete.
Is it okay to use salt as a deicer?
short answer is NO. Salt is very corrosive to concrete and
will eventually, if not immediately, cause damage to many
types of concrete.
What about "Environmentally Friendly" deicers?
are four primary types of deicing salts that all have different
characteristics and are each designed to work in certain
most common deicing salt is regular rock salt or sodium
chloride. It is widely available and can melt snow and
ice until the temperature drops below -8 C. Below these
temperatures the rock salt stops melting snow and ice.
Rock salt also releases the highest amount of chloride
ions when it dissolves. Chloride can pollute water ways,
rivers, lakes, and can also cause metal to corrode.
Calcium Chloride is another deicing salt that is commonly
marketed in tiny white pellets. It can melt snow and
ice well below -17 C. It can cause skin irritation if
your hands are moist when using it and will chemically
Chloride is another deicing salt that is now available.
It is not a skin irritant and will not harm vegetation
but will only melt ice and snow when temperature is
above -9 C.
The newest deicing salt is Magnesium Chloride. It will
continue to melt snow and ice well below -25C. This
salt releases about 40 percent less chloride into the
environment than either rock salt or Calcium Chloride.
It can be less damaging to concrete surfaces of unknown
or questionable quality.
common property of all different types of deicers is that
they all seem to have the potential to damage concrete and
some are harmful to the environment. Another potential problem
with using a deicer of any kind is the damage caused by
increased freeze/thaw cycles. For example, when a product
rated for -9 C melts snow and ice, it will enter the pores
of the concrete as salty water. When the temperature drops
below the rated temperature for that particular salt it
can refreeze and expand in the pores of the concrete causing
types of salt deicers are marketed as "Environmentally Friendly".
