Asphalt is very susceptible to damage from the elements and cars that drive over it. Sealcoating provides an extra layer of protection to prolong the life of a pavement surface. The coating also fills in cracks and helps the underlying material last longer. The protective coating shields the paved area from UV rays and other harmful chemicals that degrade asphalt over time. The resulting protection reduces the risk of damage from heavy traffic and improves the aesthetic appearance of a parking lot or driveway.

The sealing process involves applying a thin layer of asphalt over the existing pavement surface. The coating is mixed with sand and fine particles to create a textured finish that helps seal the paved surface. It is then sprayed onto the surface by hand or spraying equipment. The contractor may use coal tar or an acrylic polymer mix to create the sealant. Coal tar is more effective than water-based acrylics. However, it contains volatile organic compounds, which are harmful to the environment and may contribute to contaminating soil and water. Water-based acrylics do not contain volatile organic compounds and are safer for the environment.

Sealcoating protects the underlying asphalt from damage caused by weather, oil spills, motor fuel leaks and other chemicals that can break down its structure. It also replaces fine particles that are lost from the asphalt surface due to oxidation, ensuring that the binder remains flexible and strong enough to support vehicular pressure. Without this protection, the deteriorated asphalt will lose its structural integrity and develop into unsightly potholes.

In addition to preventing potholes, sealcoating preserves the condition of an asphalt pavement, which saves money in the long run by reducing the need for costly repairs. In addition, the protective coating enhances the appearance of a parking lot or driveway and increases safety for pedestrians, motorists and cyclists.

The application of sealcoating requires a good level of personal protective equipment (PPE). Workers should wear coveralls, face masks and safety glasses when working with the spraying machinery. They should also be aware of the risk of exposure to toxic fumes and particulates released during the spraying process.


In addition to making the asphalt look brand new, sealcoating also fills small cracks and prevents water penetration. This can help the pavement last much longer. However, you should be aware that the lifespan of a sealcoating job depends on a variety of factors. Some of these include the climate conditions, amount of traffic, and even the time of year. A good seal coating contractor will be able to tell you how long the job should last before it needs to be repeated.

Another factor that can affect the longevity of a sealcoating job is the type of binder used in the mix. The binder is the liquid component that binds all the other ingredients together and ensures proper consistency. It can be made from a variety of materials, including refined coal tar, petroleum, asphalt refinishing oil, and polymer resins. However, it’s important to choose a high-quality product for best results.

To extend the lifespan of a sealcoating, property owners should keep it clean and do regular maintenance. Proper cleaning and sweeping can remove dirt, oil, and other material that can erode the surface. They should also repair potholes and cracks promptly to prevent water from penetrating the base layers. It is also important to avoid using chemicals on the paved area.

Sealcoating is a great way to protect your asphalt surface, but it does not last forever. It is recommended that you get it resealed every 3-5 years. The cost of the service is minimal compared to the amount of money you can save by preventing costly repairs.

The process of applying a seal coat requires certain equipment and tools. For example, you will need a hot pour crack fill machine, brooms, blowers, and a spray system. These will allow you to perform the work faster and more efficiently. It is also important to have adequate personal protective equipment (PPE) for the job. This includes gloves, a face mask, and safety glasses.

The climate must be warm and dry for the job to be successful. If rain is forecast within 24 hours, workers should postpone the project until the weather clears up. Moreover, vehicles should not be driven on the pavement for at least 24 hours after application.


Sealcoating gives asphalt pavement a rich black, shiny appearance and provides an attractive curb appeal for visitors and tenants of your commercial facility. Aside from its aesthetic benefits, it also helps protect the underlying asphalt from oxidation, which is the leading cause of damage to the pavement. It is a proactive measure that minimizes the need for costly repairs and extends the life of your blacktop parking lot.

Before the application of any seal coat, it is important to ensure that the paved surface is clean and dry. Moisture can hinder the adherence of the asphalt coating, so it is essential to thoroughly wash the surface to remove any dirt, debris, or residual substances that may prevent proper adhesion. After washing, it is a good idea to repair any pre-existing cracks, potholes, or other structural defects in the paving material.

Aside from the aesthetics, a fresh coat of sealant can help improve the efficiency of your paving material. It will make the paved surface easier to clean and more durable, and it will also allow for quick maintenance work. As a result, it is recommended to apply a new layer of seal coat every three to five years to maintain the maximum lifespan of your parking lot.

The materials used in a sealcoat mixture typically include bituminous coal-based liquids, water, polymer additives, silica sand and other exclusive fillers. The exact formulation varies by manufacturer, but most contain ingredients that are not classified as toxic or harmful to humans and animals. However, some ingredients do contain a small amount of polycyclic aromatic hydrocarbons, which are known to be carcinogenic to animals.

The most obvious benefit of sealcoating is its ability to enhance the aesthetics of your asphalt pavement. The smooth black application looks great, and it can complement other elements of your property, such as the landscaping and the color of your buildings. This is especially important for commercial facilities, where the paved area is often the first impression made by visitors or customers. It can give a great first impression for your business, and it will also increase the overall value of your commercial property.


Sealcoating is a great way to extend the lifespan of your blacktop. It prevents oxidation, stops weather damage and beautifies the pavement. It is an important part of your asphalt maintenance routine and can save you money on repairs. However, it is not a substitute for filling cracks and repairing damaged areas.

The cost of sealcoating varies according to the size and condition of the pavement, the amount of material required and the application method. The most popular technique is spray application, which uses a gas-powered compressor or large industrial pump. It can also be applied by hand using a brush and squeegee. It’s best to consult a professional about the right application method for your property.

A good sealcoating company will clean the surface before applying the sealant and will repair any cracks or crevices. They will also check for any moisture problems that may require a drainage system installation. It is important to do these steps before applying the sealcoat, so that your asphalt lasts as long as possible.

Sealcoating’s cost can vary from $2 to $4 per square foot. The price will increase if the paved area is heavily used and requires multiple coats of sealer. Some companies offer discounts for larger projects. It’s also worth comparing prices from different companies.

Some companies use a coal-tar product, which has been shown to cause pollution. Studies suggest that it contributes to polycyclic aromatic hydrocarbons in waterways and creek beds. It is also known to be toxic to plants and animals, especially when ingested by birds or small mammals.

If you decide to do the work yourself, it is important to choose a high-quality product and follow the manufacturer’s instructions. Avoid cheap products that might not hold up to the elements. Also, make sure to purchase the appropriate tools and supplies. In addition, you’ll need to know how to use them properly to prevent damaging the paving. Otherwise, you’ll need to pay for a full-scale project again.

DIYing can save you money, but it’s not a good idea for people with limited experience. If you don’t know how to do it correctly, you’ll risk ruining your clothes and causing skin irritation. It is also not worth the hassle of re-doing the job as a result of trial and error.
