1. Why should I have
my pavement seal coated?
Besides making your parking lot look much
better, sealers protect asphalt from the
destructive elements of weather, gas, oil
and other chemicals that damage the paved
surface.

2. How often should asphalt be sealed?
Asphalt should be seal coated every two to
three years. The amount of traffic is one
deciding factor. Surfaces the receive light
traffic, like home driveways and small
businesses, require re-coating less
frequently than parking lots receiving
moderate to heavy traffic.

3. Aren’t all brands of sealer the same?
All brands of pavement sealer are definitely
NOT EQUAL. Federal Spec. sealers
require dilution rates of up to 40% of
water. Even if several contractors use the
same product, most contractors will use mix
designs to their advantage. M&D Blacktop
follows the manufacturer’s specification. In
fact, M&D Blacktop chooses a dilution rate
of 25% - 30%; this is the low (best) end of
the dilution rate scale. Some contractors
have been known to over-dilute their sealer.
These products have lower solids content and
cannot hold as much sand, causing a slippery
surface when dried. Additionally the coating
will not perform properly and will money
wasted.

Jennite® a premium sealer, is a
product we highly recommend. M&D Blacktop is
a certified Jennite® applicator. We
have found over the years that Jennite®,
while it may cost more, will provide you
with the lasting protection available.
Jennite® is able to handle greater
amounts of sand that gives you more
protection.

4. Will sealer make the pavement
slippery?
This is a great question. Pavement sealer
will not make the surface slippery if
applied properly. We use a sand-slurry mix
of pavement sealer. Silica sand is mixed
into the sealer at a rate of 3-6 pounds per
gallon of sealer depending on the quality of
the sealer you use. Not all contractors use
this type of mix, so be sure you find out if
sand is mixed into their material. If sealer
is applied without sand mixed into the
sealer, then yes, your parking lot will be
very slippery. This is a major liability
issue for business owners.

5. How should the sealer be applied?
The best way to apply asphalt sealer is to
use the following method:
|
• |
The first coat of sealer
should be applied using a
motorized, seal coating,
squeegee machine. The squeegee
machine will help force sealer
into the pours of your asphalt
surface, filling in voids and
providing a well sealed surface. |
|
• |
The second coat can be
applied using a spray unit
specifically designed for seal
coating. This will provide a
nice even, uniform coat of
sealer, suitable for driving and
walking. |
|
• |
In some cases spraying both
coats of sealer is acceptable. |
|
• |
!! CUSTOMER BEWARE !!
Which ever method of seal
coating is chosen, it is ALWAYS
important to make sure the
equipment is specifically
designed for seal coating, has
mechanical agitation (mixing), a
proper pumping system and most
importantly is being applied by
a trained, professional seal
coating crew. |

Questions...
6. Can sealer fill
cracks in pavement?
No, sealer will not fill cracks in the
pavement. Larger cracks should be sealed
with a hot rubber crack sealer prior to
sealing.
Return to Questions...
7. What causes scuff marks in the freshly
sealed asphalt?
Scuffing usually occurs on hot days during
the first month after the sealing has been
done. This is a temporary thing and will
blend back into a smooth looking job after
time. The best way to avoid scuffing is to
be sure your vehicle is moving before
turning the wheels.
Return to Questions...
8. How many coats of sealer should be
applied?
Two coats of sealer are recommended on most
parking lots receiving moderate to heavy
traffic. A third coat of sealer is
recommended on parking lot entrances and
drive lanes where excessive wear occurs due
to constant turning and heavy traffic.
Return to Questions...
9. What is hot-pour crack sealer?
Hot-pour crack sealer is a flexible,
rubber-like product that starts out as a
solid, rubber block or cube, and is melted
down in a special melter. Once melted, the
sealer is applied over the cleaned out
crack. Once cooled, it can be sealed over,
or driven on without any problems.
Return to Questions...
10. How important is to clean out cracks
prior to filling/sealing?
It is very important to clean out cracks
prior to filling them. Debris left in cracks
will cause the crack sealant to break loose
prematurely and work free of the crack. In
cases where vegetation is growing through
cracks or there is moisture in cracks from a
previous rain, it is very important to use a
propane powered heat lance to remove the
moisture and/or vegetation prior to applying
crack sealant.
Return to Questions...
11. What is the difference between
hot-pour and cold- pour crack sealants?
Hot-pour crack sealer is melted and applied,
then cools to a pliable, rubber-like
consistency, allowing it to expand and
contract with the crack. Cold-pour crack
sealers can be a water or asphalt based
product that is applied to cracks in a
liquid form, and then dries to a solid.
Cold-pour crack sealers usually do not
perform as well, due to their lack of
flexibility when dried.
Return to Questions...
12. Can I change to a different striping
layout?
Yes, we can change your existing parking lot
layout if you wish. To do this, you must
first have the old lines painted over with
traffic blackout paint. A word of
caution....the old layout lines will most
likely be discernable as a dark shadow-like
outline under the sealer.
Return to Questions...
13. Is there a specific type of paint
that should be applied to fresh sealer?
The only types of paint that should be used
on a freshly sealed parking lot are latex or
acrylic latex waterborne traffic paints.
These types of paints will not discolor like
oil based and chlorinated rubber based
paints.
Return to Questions...
14. Will I have to close my business
while the work is performed?
No, we will do our best to keep your
business open and running while the work is
being performed. A lot will depend on the
size and number of access points available
to enter the building. If possible, we will
do work when the parking lot is not being
used.
Return to Questions...
15. Will the pavement sealer cover oil
stains?
Pavement sealer will not adhere to oil
stains unless the stain is first burned or
treated with an oil spot sealant. Even after
the spot has been treated with prime it may
reappear.
Return to Questions...
16. What are the best weather conditions
for applying pavement sealer?
Pavement sealer should only be applied when
the surface temperature is 40 degrees and
rising and there is not a significant rain
hazard in the near future. If the possibly
of rain is too great and we feel there is a
real danger in having your property damaged
or your sealer washed away, we will contact
you and re-schedule the project.
Return to Questions...
17. Can work be scheduled on a Saturday,
Sunday or holiday?
Yes.
Return to Questions...
18. How soon can I re-open my parking lot
to traffic after it has been sealed?
We can usually have your parking lot
re-opened to traffic the day after work is
completed, weather permitting. M&D Blacktop
will provide barricades and caution tape to
ensure the property is blocked off.
