Repairing Cracks

Frequently Asked Questions


Why Sealcoat?

These FAQ's are provided to better inform you about your sealcoating service. Please remember that we are always available to answer more in depth questions by phone or email.


What should I do before my sealcoating appointment?

Please make sure any automatic sprinklers are turned off 24 hours before and after your service.  If you have any ant mounds in cracks it is best to apply a pesticide a few days before the sealcoating.  The same applies for any unwanted vegetation—weed killer/vegetation killer is recommended.  Please make sure all vehicles, trailers, or other materials are removed.  If the surface has caked/baked on dirt it should be removed with a pressure washer and allowed to dry before our crew arrives. Please use a degreaser (dishwashing liquid) on any oil spills and rinse with water.  

How long does the service take?

This depends on the size, condition, and how much cleaning or repair is needed.  The average driveway without repairs takes about an hour.

How long should I stay off the seal coated surface?

In full sun you can walk on the drive in 2-3 hours.  You should not drive on it for at least 24 hours.  In the spring and fall, 48 hours is recommended.  The curing process takes 30 days so avoid the use of harsh cleaning chemicals.  Tire rubs may also occur on newly coated drives but will fade in a few weeks.

What if it rains after the driveway is finished?

Please know that Sealcoating Plus watches the weather conditions carefully.  However, if a stray shower occurs before the sealer is dry and it washes out, we will redo the service at no charge.  Please call us to schedule. 

How often should a driveway be sealed?

Asphalt should be sealed every 2-3 years.  This will protect and lengthen the life of the pavement.

Will the sealer make the pavement slippery?

We use diamond silica sand to provide a skid resistant surface when dry.  Since our tank has a power agitator the sealer is continually mixed at your site during the application process.

Are all brands of asphalt sealer the same?

Absolutely not!  Many store bought materials can’t compare with the high quality commercial grade product used by Sealcoating Plus.  Our material includes additives that increase the toughness, flexibility, and durability of the coating.  Our equipment has continuous agitation to maintain consistency throughout the application process.

How many coatings of sealcoat should be applied?

One coating of sealer is more than sufficient for the average residential home driveway.  Two coatings are recommended on commercial parking lots that have moderate or heavy traffic.  A third coating is recommended for parking lot entrances/exits or roadways where excessive wear can occur due to constant use or turning wheels.

How is pavement sealer applied?

Sealer can be applied with a brush, by spraying, or a squeegee.  We usually apply by hand using a nylon brush applicator on smaller areas such as residential driveways.  Spraying of pavement sealer is usually reserved for large, open areas such as parking lots and roadways.  Either method will result in a quality, long lasting coating when applied properly.

My pavement has some low spots that hold water; will sealcoating fix this?

No, sealcoating is a surface coating and any repairs should be addressed using hot asphalt mix prior to sealcoating.

Will the sealcoat cover oil stains?

Sealcoat will not adhere to untreated oil stains.  We recommend homeowners using a degreaser on spots prior to our service.  We always use an oil spot primer to help the sealer bond. If the spot is really saturated it my bleed through.

What causes scuff/tire marks in the new coating?

The sealcoat formula we use is sand infused rubberized product.  Newly coated surfaces can scuff in the hot sun.  Power steering marks are normal and temporary, usually occurring within the first month after sealcoating.  These marks will fade over time.

When should I seal my new asphalt?

Newly paved asphalt surfaces have excess oils that diminish during the curing process.  Typically the curing process takes 30-90 days depending on the amount of oil present in the new asphalt and the weather conditions.

Do I need to be home?

No.   Sealcoating Plus can complete the work while you are at work, on vacation, or even out running errands.  Please have the driveway clear of vehicles and automatic sprinklers deactivated the night before any scheduled services.


What is hot pour crack filler?

Hot pour crack filler is a flexible, rubberized commercial grade product used to repair cracks ¼” or larger.  It is heated between 375 degrees – 400 degrees and applied over the cracks.  It is smoothed with a v-shaped squeegee.  It seeps deep inside the crack and helps prevent further damage from water penetration. 

Does asphalt sealer fill cracks in the pavement?

Only small cracks under ¼” – the coating will fill in these small surface imperfections, but standing water in these types of areas will breakdown the sealcoat at a faster pace.

Will sealcoating “buy” a few more years of life to an old cracked drive?

The protection to the surface is dependent on the pre-existing condition, age, and amount of use. Sealcoating will slow the aging process and provide a cosmetic upgrade.  However, if the pavement doesn’t have good structural integrity and drainage the protection will be greatly diminished.  

We had our pavement crack filled and some of the cracks re-opened?

This happens due to movement during the freeze/thaw cycles here in Minnesota.  Cracks may re-open.  Crack filler is not a permanent solution, but a time buying procedure that cannot be guaranteed in our climate.  It should be maintained annually. 

Why is my crack fill flexible?

After application the crack fill remains flexible allowing it to expand and contract with the outside temperatures.   

Is the crack filler visible through the sealcoat?

Yes, you will see the crack filler because the texture of the crack fill is smoother than the texture of the asphalt.  This is unavoidable and a small concern compared to the added protection it provides.
