Q. How do I maintain my new asphalt driveway/parking lot?
A. Preventative maintenance includes crackfilling and sealing. Both should be done on an as-needed basis.

Q. What are the benefits of sealing my driveway/parking lot?
A. If applied properly, sealing benefits the pavement in many ways. It renews the dark appearance of faded asphalt, making it look and wear like new. It also protects the pavement from water penetration, gas and oil spills and the ultraviolet rays of the sun—all of which can rapidly deteriorate an asphalt surface.

Q. What is sealer and how is it applied?
A. Asphalt sealer is a water based surface treatment used to protect an existing asphalt surface. It can be applied by hand or with a spray unit. Dunn Company recommends the initial application be done by hand, with every application thereafter applied with a spray unit if practical.

Q. When should I seal my newly paved driveway/parking lot and how often should it be done?
A. We recommend the initial application be done the following year after paving. After the initial application, your driveway/parking lot should be sealed every 2 to 3 years depending on personal preference.

Q. What should I do when my asphalt driveway/parking lot cracks?
A. Crackfilling is part of the preventative maintenance required for asphalt surfaces. It should be done prior to or in conjunction with sealing.

Q. What causes potholes and how do I fix them?
A. Most potholes are caused by improper drainage or lack of base material. They can be temporarily fixed with a cold patch material. Permanent patching is available and may require extensive work. Please call for an estimate.

Q. How much will it cost to have my driveway/parking lot sealed professionally?
A. The cost of sealing a driveway depends on the amount of labor and material required to furnish and apply the sealer.

Q. Can I seal my driveway/parking lot myself?
A. Yes, but it is a very labor intensive project. The materials needed to seal your driveway/parking lot can be purchased at our office.

Q. How long should I stay off a newly sealed surface?
A. We recommend staying off the asphalt surface for a minimum of 24 hours. Weather conditions greatly affect the amount of cure time. The sealer is brown when applied and black when dry. Once the sealer is dry, it can be walked on.

Q. Will Dunn Company block my driveway/parking lot after services are completed?
A. Yes, we will block off the driveway/parking lot when we are done. You can open your drive to traffic the following day.

Q. What if it rains after my drive has been sealed?
A. Once the sealer is dry, rain will not affect it. If it is not dry, the sealer will simply wash away and will need to be reapplied.
