Sealcoating is the process of applying a sealant product over pavement. If you have an asphalt driveway, it is susceptible to damage from frequent sun exposure, heavy equipment and vehicles, and cracks from many different sources. In order to prevent this damage, you need to coat it by using the sealcoating technique. Here are some tips for sealing your driveway and expanding its life span.

Keep Safety in Mind

Before you start working on your driveway, make sure you are keeping your safety and other people's safety in mind. Wear protective gear and gloves, and warn family members not to come out to the area you are working with. Some sealants can have strong fumes, and you don't want children or pets coming near you. If you are also sealing a roadway that is used by others, make sure to set out signs so they can avoid the path of sealant.

Clean the Driveway

Your asphalt driveway should be clean of dirt, dust and debris before you start to seal it. Get out a push broom to get rid of as much dirt and debris as you can. Next, use a pressure washer to get rid of the rest of the dirt and rinse the driveway off. If there are oil or grease stains from parked vehicles, you can use a stiff brush and soapy water to scrub them away. Once you are done scrubbing the driveway, rinse it again with your pressure washer and let it dry.

Fill in Cracks and Holes

If you find cracks or holes in your driveway, it is best to fill these in before applying the sealcoating. Your local hardware store will sell a variety of crack-filling products that are appropriate for asphalt surfaces. The easiest ones to use come in a squeeze bottle, as they make it easy to control where the filler goes. You simply squeeze the product into the holes and cracks and let it dry. If the crack is too large for a liquid filler, you will need asphalt repair caulk to fill it in. Make sure before filling the cracks, you remove any debris, leaves or dirt inside.

Apply the Sealant

The easiest sealant to go with is one that is already prepared for you, though you can also get your own additives. The additives will change the texture of the finished product and how well the sealant works. For example, sand as an additive gives your driveway a rougher texture, but can also protect it from cracks. Other additives will provide additional benefits like having a darker color, better resistance to oil and grease, a longer life span for the driveway, or quicker dry time.

Apply the sealant according to the instructions on the package. The best sealcoating uses at least two coats in order to penetrate the aggregates for a deep coating. Make sure you leave your signs out to prevent people from driving on the driveway before it has dried and cured. For professional help, contact a company like Statesville Sealing & Striping.
