Frequently Asked Questions
How is seal coating applied?
We apply asphalt sealer by brush or spray, depending on the surface of the asphalt and the individual needs of the project.
Does sealer cover oil spots and stains?
Usually it does. If oil, grease and gasoline stains are extremely bad, Pro-Coat will pretreat them to help promote adhesion of the sealer. In the case of excessive oil damage, asphalt repair may be needed.
Will my asphalt be barricaded during or after seal coating?
Yes, Pro-Coat will barricade all entrances to your asphalt with orange traffic cones and yellow caution tape.
How long until we will be able to walk to drive on our asphalt after it’s sealed?
Walking can usually be done after 12 hours of drying time, while driving should be avoided for 48 hours. Pro-Coat can accommodate businesses that are open 24 hours by adding special additives to the sealer and/or sealing certain areas of the parking lot at a time.
How often should my asphalt be sealed?
Newly laid asphalt should be sealed within one year. After that, the asphalt should be sealed every two to three years. Some businesses that experience a large volume of traffic may seal every year to avoid expensive repairs and maintain an aesthetically pleasing parking lot or driveway.
Note: Asphalt should only be sealed when 50% of the aggregate has wore off. Over sealing will cause the asphalt to develop small surface cracks resulting from a buildup of sealer.
Will sealer make my pavement slippery?
Sealer will not make the surface slippery if applied properly. Pro-Coat uses a sand-slurry mix of pavement sealer. Silica sand is added at a rate of 2-6 pounds per gallon of sealer depending on the application and time of year. If sealer is applied without sand, it can become very slippery when wet and can become a major liability issue.
Does sealer fill in cracks in the asphalt?
No, sealer will not fill in cracks in the asphalt. Sealer is a liquid that will absorb into the cracks in a short amount of time. Cracks should be filled prior to seal coating.
Why are there marks where my tires turn on my freshly sealed surface?
It actually takes a full 2 weeks for sealer to cure. During that time, if someone drives and isn’t moving while turning their tires, more than likely power steering marks will be seen.
