Seal Coating FAQ

Why should I have my pavement seal coated?

Besides making your pavement look new again, pavement sealer protects pavements from the destructive elements of the weather, gas, oil, antifreeze, and many other chemicals that could damage the paved surface.


How soon can new pavement be seal coated?

Newly paved asphalt surfaces should not be sealed until they have sufficient time to cure. Curing allows the excess oils that are always present in new asphalt to diminish through a process called oxidation. We usually recommend that the asphalt be allowed to cure for one year prior to seal coating for the first time and then sealed every one to three years.


What is Crack Sealer?

Crack sealer is an elastic material designed to seal cracks against moisture which is one of the leading causes of pavement failure.


How often should pavement be seal coated?

Asphalt pavement should be sealed every one to three years depending on the amount of traffic surfaces that receive light traffic like home driveways would require sealing less often than parking lots receiving moderate to heavy traffic.


Will the pavement sealer cover oil stains?

Pavement sealer will not adhere to oil stains unless the stain is treated with an oil stain primer prior to seal coating.


What causes scuff marks on newly sealed pavement?

Scuffing of the newly seal coated surface may occur on hot days. Scuffing is normal and temporary usually occurring within the first month after the seal coating has been applied. The best way to minimize scuffing is to prevent sharp turns when driving a vehicle on the surface.


How long does it take the material to dry?

This depends on how many coats are applied and the weather conditions. Plan on a full 48 hours before driving on the pavement.


How should pavement sealer be applied?

Seal coating can be applied by spraying. Spraying of pavement sealer is usually reserved for larger driveways and open areas such as parking lots and roadways. Either method will result in a quality, long lasting coating.


Will pavement sealer make the pavement slippery?

No! Pavement sealer will not make the surface slippery. We use a sand slurry mix of pavement sealer. Silica sand is mixed in with our pavement sealer resulting in a non-slip surface.


How do you block off sections in a parking lot?

Developing a plan to section off the parking lot to maintain traffic flow through the project is critical to its success. Tenants must be informed throughout process so they can plan accordingly. Each area is blocked off with orange traffic tape, barricades and or traffic cones. Each parking lot is different so the sectioning plan and barricading plan must be customized to the needs of the tenants and the property manager.


Why are there tire marks showing on a newly seal coated parking lot?

The material dries to the touch in a few hours, but it takes several days to fully harden, especially in the hot sun. Expect power steering marks as the sand is sheared away from the coal tar but over time these marks will dissipate.


Why is sand important?

Sand is added to the coal tar at the rate of 3-5 pounds per gallon of concentrated coal tar. It is used to prolong the wearing life of the material and provide skid resistance, but it is important to have the right particle size to work effectively.
