When you’re spending the money to have your driveway or parking lot professionally paved, you don’t want the asphalt to deteriorate any sooner than necessary. Sealcoat the surface to protect your walking and driving areas from wear and tear.
Have you noticed cracks or holes forming in your asphalt driveway or parking lot, thanks to years of car and foot traffic? Or are you laying down new pavement and want to make it last as long as possible? Professional pavers employ a process known as sealcoating to lengthen the life of an asphalt surface. Sealcoating will not only make your driveway or parking lot more durable but will also help it maintain its clean, smooth look in the face of repeated use. Contact a paving contractor in your area to discuss whether sealcoating is right for your new or existing asphalt surface.
How It Works
As tough as it is, asphalt can be damaged by sun exposure, excessive rain, ice, and temperature changes. Years of gasoline and oil drippings from cars can also cause surface deterioration. Not only will deteriorating asphalt fade from a crisp black to an ugly gray, but it can also become rough and crack open-and water accumulating in pavement cracks or holes can lead to further damage. Sealcoating a pavement area approximately 60 days after the initial asphalt application will protect it from weather and car fluid damage in the years ahead, lengthening the overall life of your paving. Driveway sealer is composed of a coal-tar emulsion, sometimes fortified with rubber or silica sand for increased durability. A paving contractor will apply sealer either by brush or by spraying it over the area; the method may depend upon the size of the area to be sealed, or upon the individual contractor’s preference.
Repair and Resealing
If you want to seal a driveway or parking lot that is several years old and has already begun to deteriorate, the paving contractor must first repair the damaged asphalt. This may involve filling any holes or cracks in the pavement, as well as smoothing out rough areas. It’s also a good idea to clean up any oil stains before applying sealcoating, as once they’re sealed in, those stains are permanent. In general, you should apply a new coat of driveway sealer every two to three years. Resealing and minor repairs will almost always be less expensive than having to completely replace the pavement.
Having a sealed driveway or parking lot surface has benefits far beyond the money saved on re-paving. For starters, the smooth, sealed finish will be easier to clean than cracked, stained asphalt, enabling you to keep your property looking its best. Even more importantly, sealed pavement is safer to walk and drive on. Large cracks and holes can pose a tripping hazard for individuals of all ages. Meanwhile, brittle, deteriorating asphalt can form potholes, which can prove hazardous to drivers. Properly maintaining your driveway or parking lot area by sealcoating the asphalt will protect both your investment and the individuals who use the space.
