How Sealcoating Helps Extend the Life of Asphalt

Sealcoating is one of the most cost-effective ways to extend the life of asphalt. It protects paved surfaces from damage caused by oil, water, chemicals, and the sun’s harsh UV rays.


Before beginning the project, professional contractors will assess your parking lot or driveway for signs of deterioration, including cracks, potholes, and oil stains. Then, they’ll clear and block off the area to be seal-coated.

Asphalt is a very durable, but it can still be damaged over time by weather and other environmental factors. Sealcoating protects your asphalt from these issues and helps extend its lifespan.

The process involves applying a coat of liquid asphalt to the surface of your driveway or parking lot. The sealant forms a protective layer that shields the pavement from harmful chemicals, ultraviolet sun rays, and moisture. It also fills in small cracks and chips, preventing them from getting bigger over time.

If you are a homeowner or business owner with an asphalt driveway, then sealcoating is an important investment. Without this service, your paved driveway will start to degrade over time and will look faded, worn out, and even crumbly. Sealcoating will prevent this from happening and will give your driveway a fresh, like-new appearance.

In addition to protecting the surface of your asphalt, seal coating makes it much easier for you to maintain your driveway. The smoother surface of a sealed driveway is easier to wash and will be less likely to hold onto debris such as sand, dirt, and leaves. It is also a safer surface for walking and driving on, as the sealant contains additives that help reduce slippage.

One of the main reasons for asphalt deterioration is water seepage through cracks and chips in the pavement. If the cracks aren’t filled, they can become larger over time and may cause further damage to your asphalt. Sealcoating stops this from happening by filling in the small cracks and forming a barrier between the water and your asphalt.

In order for your sealant to adhere properly, it must be applied to a clean surface. Before sealing your driveway, hire a professional asphalt contractor to sweep away debris and power-wash any oil spills or other contaminants. Then, the contractors will mix the sealant in a large tank and use a sprayer to apply it evenly over your entire asphalt driveway or parking lot.

Keeps It Looking Great

Asphalt looks a lot better when it’s sealcoated, so you get a much nicer curb appeal. A freshly-sealed blacktop is smooth, glossy and blacker, and it’s a big improvement over the gray, worn, patchy and stained look that happens after years of exposure to harsh weather, automotive fluids and UV rays.

It also increases the skid resistance of your driveway, so you don’t have to worry about your car sliding as you drive on it. Having your asphalt driveway or parking lot regularly sealcoated saves money in the long run compared to having it repaired every time it gets damaged or worn.

In addition, when your pavement is sealcoated, it prevents water penetration that damages the surface. This damage comes about during cycles of freezing and thawing, and it starts at small defects in the surface that eventually eat away at the asphalt and cause cracks. Sealcoating closes these small openings and protects the pavement from further damage, stopping the cycle before it has a chance to become worse.

When you sealcoate your pavement, it becomes easier to clean. The sealer helps keep stains from setting in, and it’s easier to wash off spills and grime than if the pavement were untreated. The shinier your asphalt is, the more attractive it looks, so you get the benefit of boosting your home’s curb appeal as well.

Sealcoating is a simple process that has a huge impact on your asphalt driveway or parking lot, so it’s worth the investment. By preventing further damage and keeping the surface looking great, you can save yourself thousands of dollars in costly repairs down the road.

Prevents Water Damage

Asphalt is tough and durable, but without the proper protection it can become damaged from a variety of sources. This includes water damage that is the root cause of potholes and other types of pavement damage. Sealcoating prevents water from seeping into cracks and fissures in the pavement surface. This prevents the cracks from getting bigger and helps the asphalt stay flexible to resist pressure.

It also prevents the penetration of oil and other chemical substances that could damage the surface. By protecting your paved surfaces, you can avoid costly repair bills that may otherwise lead to the need for full replacement.

Sealcoating is typically comprised of a blend of a liquid asphalt binder such as bitumen or coal tar, sand, and other fine particles. Depending on the brand of sealcoating that is chosen, there are other ingredients added that serve specific purposes such as drying quickly, altering sand suspension, adding resistance to salts and chemicals, improving flexibility, or providing UV protection.

Properly applying a seal coat to your pavement is the best way to protect it. However, it is important to keep in mind that your pavement should be in good condition before sealcoating can be applied. It is not meant to fill in cracks or repair existing damage. If you have any cracks, dry patches, or faded areas in your pavement, those should be repaired before applying the seal coat.

A professional company that specializes in pavement maintenance, repair and sealcoating should be used for the application of the seal coating. They will have the equipment and know how to properly apply a seal coat to your pavement that will last for several years. They will take into consideration the climate conditions that are best for the application of the sealcoat as well as the amount of traffic and use that your driveway or parking lot gets.

It is a good idea to get your driveway or parking lot seal coated at least once every few years. The cost of sealcoating is relatively cheap and compared to the costs associated with repairing or replacing your pavement, it is well worth the investment.

Prevents Frozen Roadways

A paved surface that isn’t seal coated can be damaged by the sun, freezing weather and other factors. It can crack and deteriorate quickly, especially in the winter, when water seeps into small cracks and freezes. The freeze-thaw cycle is what leads to potholes and other forms of pavement damage. Seal coating prevents this by filling in surface voids, protecting asphalt from water and the sun’s harsh UV rays.

If you don’t want to deal with the hassle and expense of repairing or replacing your driveway or parking lot, then it is time to call in the experts for a protective seal coat. Seal coating not only extends the life of your asphalt driveway or parking lot, but also makes it look better and increases its value. Whether you plan on selling your home or just enjoy the convenience of a smooth, attractive and long-lasting driveway, it is well worth the investment in the end.

The asphalt used in driveways and parking lots is made from rocks, stones and gravel that are held together by a binder, typically petroleum-based, called asphalt cement. The job of asphalt sealing is to put a protective layer over the asphalt cement that keeps it from breaking down due to elements like rain, water and UV rays, as well as oil and gasoline.

It is best to sealcoat a driveway in the spring or fall. This is because the temperature needs to be above 50 degrees Fahrenheit and the weather must be free of heavy rain for 24 hours after the seal coating process has been completed. This allows the seal coat to dry and harden before cars are allowed on the new asphalt.

Seal coating should be done regularly to maintain the benefits it provides. The cost to do so is relatively low when compared to the expense of repairing or replacing a damaged driveway or parking lot. It is the best and least expensive way to protect your asphalt investment and keep it looking great for years to come.

The tar used in the seal coating process is an emulsion of water, silica sand and other additives. This mixture is spread over the asphalt surface using a rubber squeegee or spray.
