Sealcoating Is a Low-Cost Maintenance Option

Sealcoating is a low-cost maintenance option that can extend the life of asphalt paving. It can also protect paved areas from damage caused by UV rays, rain and snow, and vehicle fluids.


Common signs that it’s time to reseal include gray spots on the pavement, fine cracks, and weeds. The process of resealing is typically completed in two coats for consistent coverage. To learn more, visit

Sealcoating can add a sleek, attractive appearance to asphalt pavement and can dramatically increase curb appeal. This can help a home or business stand out from the competition, which may increase the value of the property. However, it is important to understand the costs associated with this process before making a decision.

The cost of sealcoating can vary depending on the type of pavement, its condition and the size of the area to be sealed. For example, a small driveway will cost less than a larger parking lot. In addition, the cost of sealcoating can increase if the surface is in poor condition or has cracks and voids that need to be filled.

A well-maintained driveway or parking lot can last longer than an unpaved surface, saving the owner money and time. Moreover, sealcoating prevents weather damage and extends the life of the asphalt. As a result, it can save up to 50% in repair bills and maintenance fees over the life of the pavement.

While the benefits of Sealcoating are substantial, the process can have negative environmental impacts if not properly performed. For example, the application of coal tar-based sealcoats releases volatile organic compounds into the air, affecting air quality. Moreover, loose particles of this material can be carried by rainwater or runoff into soils, stormwater catch basins, and lakes. This can affect the aquatic ecosystems of these areas and pose a health risk for humans and wildlife.

In order to ensure that the environmental impact of Sealcoating is minimal, professional contractors should follow strict best practices. First, they should ensure that any cracks and voids are filled before applying the sealcoat. Then, the surface should be swept clean to remove any dirt or debris that may have accumulated. Finally, the weather conditions must be ideal for the application of the sealcoat. It should not be too hot or cold, and the humidity must be low. If rain is forecast within 24 hours, workers should postpone the project until it is drier.

Another way to reduce the environmental impact of Sealcoating is by using low-VOC or zero-VOC products. This will help reduce air pollution and protect human health. Additionally, contractors should have absorbent boom material on hand to mitigate any wash-offs that may occur during or shortly after the application of the sealcoat.


Sealcoating is a black, viscous liquid that many asphalt parking lots, driveways and playgrounds across North America use to protect the underlying pavement, and to give it a fresh, new look. It also helps fill in small cracks and voids. However, coal tar emulsion sealcoat is a source of polycyclic aromatic hydrocarbon (PAH) contamination in urban and suburban areas, and is a significant concern for human health and aquatic life.

Fortunately, advances in technology have made it possible for contractors to produce low-VOC or zero-VOC processes that are significantly less harmful to the environment. This means that sealcoating can be done in an environmentally responsible manner, without sacrificing quality or effectiveness.

It is important to remember that Sealcoating is a toxic chemical process, and the workers who perform it must be aware of this. This is because the chemicals used in sealcoating are often carcinogenic, meaning that they can cause cancer and other serious diseases when inhaled or ingested. This is why it’s critical that the right safety measures are in place to ensure that workers are protected.

The best way to protect yourself and your workers is to follow the instructions provided by the manufacturer of the specific sealant being used. This will help ensure that the sealant is mixed properly and is applied in the proper conditions. It is also recommended to wear personal protective equipment when working with sealcoating, including rubber gloves and masks.

Another important consideration when deciding to seal your property is the weather. It is vital that the pavement be dry for a minimum of 48 hours after sealcoating to allow it to fully cure. It is also a good idea to shut off lawn sprinklers during this time.

Finally, it is essential to choose a company with a reputation for quality work. This will ensure that your sealcoat job is done correctly, and it will last for a long time. In addition, it is a good idea to get quotes from multiple companies to compare prices and services. You should also make sure that the company you choose is licensed and insured.


A fresh coat of sealcoating can improve the look and feel of a commercial parking lot, and it can also reduce damage caused by heavy vehicles. It can be applied to asphalt, concrete and gravel lots. However, it’s important to choose the right type of sealcoating for your needs. Whether you want a durable coating or a more decorative option, it’s important to find a professional sealcoat company that can deliver results.

Aside from enhancing your parking lot’s appearance, sealcoating is also safe for people who work on the surface. During application, workers need to wear a full set of personal protective equipment including long-sleeved shirts and pants, impervious gloves, safety goggles and a hard hat. It’s also a good idea to keep a first-aid kit on hand in case of any accidents.

Preparation for sealing can take up to a day and it’s essential that the asphalt is clean before the application of sealcoat. Oil, dirt, and other debris can cause the resulting sealcoat to flake or deteriorate. Effective cleaning methods include using a gas blower, degreaser and scrub brush.

It’s also important to make sure that the sand used for the project is of the correct size to produce the desired traction and texture. Too large particles will interfere with the curing process and cause premature wear and shedding. Too small will result in a sloppy finish and may not produce the desired traction.

The use of coal tar-based sealcoats can have adverse environmental effects. In fact, it has been shown that ingesting soil and dust contaminated with the residue can be toxic to fish and other aquatic organisms. Many states have banned the use of coal tar sealants due to this risk. However, asphalt-based sealants contain less PAHs and are safer for human skin contact than refined tar-based sealcoats.

If you’re a property owner or manager, consider hiring a professional sealcoat company to apply a high quality, lasting coating to your asphalt pavement. The results will be worth the extra cost, especially if you have customers who regularly visit your business. A smooth driving experience will make for a more positive customer experience and increase their satisfaction with your service.


Sealcoating is a quick and easy way to protect your asphalt driveway or parking lot from damage caused by UV rays, rain, snow, oil and gasoline. Unlike crack fillers, which treat existing problems, seal coating prevents them from occurring in the first place. It also extends the life of your paved surface and makes it look better.

To get the best results from your Sealcoating project, it’s important to take the time to prepare the area before applying the material. This includes blowing or sweeping the pavement to remove loose debris and dirt. It is also necessary to power wash the surface to remove any oil, chemicals or other contaminants that may interfere with the bonding process. It’s also a good idea to treat any oil stains before sealing the area. This will help ensure that the new seal coat will adhere properly and last longer.

Once the seal coat is applied, it takes a few hours to dry and cure. During this time, it’s important to keep the area clear of cars and other vehicles. This will help the asphalt dry faster and prevent vehicle tires from tracking or damaging the sealcoat. It’s also a good idea not to walk on the sealcoat until it is completely dry. If you do, the sealcoat will scuff and will look gray instead of the normal charcoal black color.

Choosing the right day to perform a Sealcoating project can also impact how long it takes for the asphalt to dry. The temperature, humidity and precipitation will all affect how well the sealcoat adheres to the pavement and how quickly it dries and cures.

It’s a good idea to check the weather forecast for the day that you want to apply the sealcoat and to schedule the project for a sunny day with no rain in the forecast. If it does rain on the day that you are planning to apply the sealcoat, you should wait until the next day to complete the project.

While it may seem like the Sealcoating job will take a lot of time, it is actually much quicker than most people expect. The prepping and cleaning processes can take up to a full day, but the actual application of the sealcoat only takes a few hours per area.
