Driveway Sealcoating questions, answered by experts

It is not recommended to seal brand-new or uncured asphalt immediately after installation. You should wait at least three months to allow the asphalt time to cure. Applying a seal coat too soon can trap the asphalt's oils and chemicals, preventing it from fully hardening. This can lead to a weaker surface that is more vulnerable to damage. After the initial three-month curing period, applying a seal coat can extend the asphalt's life by protecting it from water, UV rays, and other damaging elements.

The costs range from $0.15 to $0.50 per square foot, depending on the asphalt condition, sealant type, and labor.

A properly applied asphalt driveway sealer, or sealcoat, should last between one and five years. The industry standard is to reseal every two to three years for optimal protection. If you live in a climate with extreme weather, such as heavy rainfall or freezing temperatures, you may need to reseal your driveway more frequently, around every two years. Signs that your driveway needs a new coat of sealant include the appearance of small cracks or uneven drying after rain.

Though they may look similar, tar and bitumen come from different sources. Bitumen is a petroleum product—extracted during crude oil refining—and is mostly made up of hydrocarbons. Tar comes from burning down organic materials like coal or wood. Bitumen is strictly oil-based, while tar is a mix of compounds from natural sources. Both are used as binders in paving; however, bitumen is the standard for today’s asphalt. Tar use has mostly faded out of road construction.

Sealant comes in 5-gallon buckets that can cover up to 400 square feet. Measure your driveway to get the exact square footage, and remember to factor in enough sealant for two coats.
