How Can You Tell If You Should Sealcoat Your Asphalt Driveway This Spring?

If you're a homeowner with an asphalt driveway, you may have heard that sealcoating is an important chore that needs to be completed periodically in order to protect the driveway from rain and other forms of precipitation. If you've never sealcoated your driveway before, you may have a few things to learn about what sealcoating is, how you can tell when it's time to sealcoat, and other important details. This FAQ will teach you some of the things you need to know about sealcoating.

How can you tell if you should sealcoat your asphalt driveway this spring?

An asphalt driveway that needs to be sealcoated will turn a light gray color. When it rains, the water will soak into the asphalt instead of beading up on the surface and then rolling off. An asphalt driveway that needs to be resealed may also develop hair line cracks in the surface of the asphalt.

What does asphalt sealcoating do?

Sealcoating covers the asphalt in a water-resistant coating that prevents it from absorbing water. Since water can destabilize the base beneath the driveway and can also break apart the asphalt during freeze/thaw cycles, sealcoating helps extend the service life of the driveway.

Will sealcoating repair your driveway if it is damaged?

Sealcoating closes the pores of the driveway. It does not patch potholes or make other repairs to the surface of the asphalt. If your driveway has gouges and deep cracks in the surface of the asphalt, it will need to be repaired before it is sealcoated.

Can you sealcoat and repair your driveway as a DIY project?

A motivated DIYer can sealcoat and repair their own driveway. Driveway patch kits and crack sealers are available at home improvement centers and hardware stores. All holes must be patched and all cracks plugged before the sealcoating can take place. Follow all manufacturer's instructions when patching, repairing and sealing the driveway. Remember to note the recommended outdoor temperature indicated by the manufacturer, and do not attempt to repair or sealcoat the driveway when the temperature outside is too cold or hot. Check the weather forecast for spring showers before starting this project. Give yourself a rain-free day to patch the driveway, a rain-free day to sealcoat, and a couple days to allow the repairs and sealcoat to cure.

Don't forget that you can also have your driveway repaired and sealcoated by a professional asphalt repair company. Professional companies may have access to industrial-grade driveway repair and sealcoat. In addition, professional companies are adept at asphalt repair and sealcoating, and thus may be able to produce superior results.
