What is Seal Coating?
Parking Lot Seal Coating or Driveway Seal Coating is the act of placing a
liquid emulsion called sealant over an asphalt base. It is typically applied
over clean asphalt with rubber squeegees to seal and protect the asphalt
surface of your lot or driveway. It is recommended that you seal coat your
parking lot or driveway every 2 to 5 years, depending on the use and wear.
The main reason to apply new seal coat to your lot or driveway is to protect
the number one investment on your property, and thats your asphalt. Seal
coating is to asphalt what sunscreen is to your shin. It keeps the asphalt
protected and safe from the harsh elements. The primary cause of failure
of asphalt is the penetration of water into the asphalt base. Oxidation of
the pavement surface begins this process which causes the asphalt to dry
and become brittle. This oxidation leads to the erosion of the top layer of
the fine particles and the appearance of larger stones and small cracks on
the surface (See Crack Repair). If left untreated, these cracks grow over time
and eventually allow water to penetrate to the base of the pavement. When
this happens, the base material moves and settles leading to further
cracking. When the pavement reaches this stage the only option is removal
and replacement of the old asphalt, which cost the most. Protect your
investment now, before this happens to your parking lot or driveway.
How Does Seal Coating Help?
Seal coat seals the asphalt pavement, preventing the oxidation and erosion
of the top layer of asphalt. On older pavements, seal coating replaces fine
particles lost from the asphalt surface due to oxidation. Seal coating seals
the small cracks that can turn into large cracks and prevents water from
seeping down to the base material. Seal coating also protects the asphalt
from the sun as well as harmful effects of chemical spills such as oil and
gasoline. Seal coating provides an attractive black surface that is ideal for
painting lines and other markings and it also leaves a smooth, clean surface
ideal for sweeping, which lowers the cleaning cost. Seal coating costs
pennies per square foot compared to the dollars needed to repair or
replace damaged asphalt.
