Asphalt Seal coating is designed to do two things; protect your
asphalt surface first and second, to improve the appearance of
the asphalt pavement. If asphalt is properly installed and
protected with seal coat, your pavement can last significantly
The most important part of seal coating is protecting the
existing asphalt surface. Protection is provided by closing
hairline cracks and putting a water resistant barrier between
asphalt and the deteriorating effects of moisture seepage,
ultraviolet radiation and ozone. It can also minimize raveling
(loss of aggregate) and fill minor voids in the asphalt surface.
Not only does seal coating protect your pavement surface it
significantly improves the overall appearance of the asphalt.
Seal coat is a mineral filled, fortified asphalt emulsion sealer
engineered to protect asphalt pavements from oxidation and
Asphalt preparation is essential prior to seal coating older pavement.
Before seal coating there are a few things that should be considered
before moving forward.
Remove and Replace deteriorating asphalt
Pothole patch any areas needing patched
Route, Clean and Fill any cracks that are in the asphalt surface
Once all of these things are considered and taken care of then Seal
Coating of the asphalt can proceed. Seal Coating is a Five
Step Process that takes time and precision to do it right.
The First Step
is to remove and replace any deteriorating asphalt that may exist
in the parking lot. Some examples are soft spots, alligatored
areas, and potholes. All these issues should be taken care of
before the application of seal coat to ensure proper protection
and a uniform appearance.
The Second Step
is to route all the cracks in the asphalt surface. This ensures
that the crack will have uniform thickness, making for a stronger
longer lasting bond. Next the crack has to be blown out and dried
to ensure proper adhesion of the hot applied crack fill material.
Once those steps are done the crack can be filled with hot
applied asphalt crack filler. This prevents the crack from
opening back up and getting any larger.
The Third Step
is cleaning the asphalt which is considered to be the most
crucial part of the seal coating process. We thoroughly shovel,
broom, blow and sweep up all the dirt and debris that is on the
asphalt surface. This prepares the surface for the seal coat
The Forth Step is to apply the seal coat. For
this we have two trucks with spray mounted equipment to apply the
material. We start out by cutting in all the edges with two foot
wide brooms ensuring all edges are thoroughly covered. Once the
edges are cut in we then spray the material to create a uniform
thickness on the entire asphalt surface.
The Last Step is parking lot striping. No
parking lot is complete until a fresh coat of paint is applied
where the existing lines were.
(IMPORTANT NOTE: We also have seal coat squeegee
machines available if your project requires a different type of
process than the one stated above)
Regular Seal Coating Can Save Money
Besides keeping your asphalt looking brand new, asphalt seal
coating can save money. Over a 15 year lifespan, unsealed asphalt
maintenance costs average $8.80 per square yard. Sealed asphalt costs
average $2.57 per square yard. With a regular program of seal coating
You Can Save 243% in Maintenance Cost.
