Sealcoating Frequently Asked Questions


Your driveway or parking lot is constructed of “blacktop”. Blacktop is made up of gravel, sand, and asphalt. Asphalt is a naturally occurring by-product of the crude refining process. Asphalt is the bonding agent in blacktop. Concrete driveways are composed almost the same way. Concrete consists of gravel, sand and cement. Cement is the bonding agent in concrete. Blacktop driveways have special needs in order to continue providing an attractive and well-maintained surface. Sealcoating is a major step in protecting your investment. A regular sealcoating schedule will save you money by extending the life of your driveway.

Air, sunlight, and freezing causes asphalt to oxidize. This results in the asphalt becoming brittle with cracks forming. Gasoline & oil can literally eat away an unprotected driveway. Proper sealcoating prevents this from occurring.

A new driveway or parking lot should be sealcoated after it has cured for 90 days of average 70 degree weather. It is important to wait this amount of time in order to allow the asphalt to cure. If a new driveway is sealcoated before the asphalt has cured the area will remain soft for a very long time. This will result in dents caused by kickstands, heavy objects. etc.

When cracks appear, they allow dirt, debris, water and gasoline to seep down to the underlying base of the asphalt. Dirt and debris can harbor plant life that is not only unsightly but can cause cracks to be forced larger because of their root systems growing into the base and body of the drive. Freezing water will eventually stress the cracks into ever larger cracks that drastically shorten the life span of the asphalt. Gasoline and oil will eat away at the structure and destroy the asphalt.

The best way to repair cracks is to first properly clean and prepare the cracks. All loose debris and plant materials need to be removed. This can be accomplished by hand or with the aid of a heat lance. Deep cracks need to be partially filled with sand before repairing. Hot rubberized fillers are the best way to fill cracks. These fillers are heated to a temperature between 380 and 400 degrees Fahrenheit. This forms a bond with the asphalt and allows the filler to move with the pavement to ensure a good seal. Large holes need to be filled with a cold patch filler.

Simple jobs can be done by the homeowner but the results are usually not good. A professional sealcoating company will have the knowledge and experience to properly protect the asphalt.
