Why Sealcoating Is a Cost-Effective Solution for Paved Areas

Sealcoating keeps damaging water from penetrating paved surfaces, extends its life, and improves surface traction. It also adds curb appeal to a home’s driveway or business parking lot.Sealcoating

Asphalt seal coat is made from refined coal tar or other petrochemicals. It dries rapidly, but releasing all water from the lower layers takes time and requires the right conditions to achieve optimum performance. To learn more, visit

In order for asphalt sealcoating to be effective, the ground and air temperatures must be in a specific range. In addition, the pavement must be free of moisture to allow the sealant to bond with the surface. Taking these factors into consideration, it’s crucial to understand the weather conditions that impact sealcoating so you can schedule your parking lot maintenance services accordingly.

Most manufacturers recommend applying their products when the ground and air temperature are around 70 degrees, with a low humidity level. These ideal conditions will ensure that the applied sealant dries quickly and effectively. However, if the pavement is excessively hot, it can bake the sealant and affect its durability and adhesion. In these cases, it’s recommended to wait until the temperatures cool down and apply the sealant in the early morning or evening hours.

Another factor that can affect the quality of the finished product is the humidity level. Humidity can interfere with the evaporation process, resulting in an extended curing time and a less-than-ideal outcome. To avoid this, the paving contractor should schedule sealcoating when the air is dry and the humidity level is below 60%.

It’s critical for paving contractors to monitor the weather forecast before performing asphalt sealcoating to ensure that conditions are suitable. If a sudden storm is predicted, it’s best to delay the project until the skies clear up. Sealant that is applied during wet weather will wash away, leaving the surface unprotected and potentially jeopardizing the lifespan of the pavement.

Wet weather also increases the reopening time for your parking lot, inconveniencing customers and employees. Therefore, it’s important to choose a reliable sealcoating company that is experienced in working with these conditions and can provide the same high-quality results despite the challenges they may face.


Sealcoating helps preserve asphalt pavement and adds a rich, dark color that improves curb appeal. It also provides an extra layer of protection against the elements, especially heat and cold, water, oil, and chemicals. It can extend the life of a parking lot or driveway up to three times as long as proper maintenance is implemented.

To ensure that the sealer bonds properly with the asphalt surface, it is important to prepare the area before a sealing project is started. It is recommended that the area be swept and cleaned prior to application of the sealer. This will remove any dirt, loose pebbles, or debris that could prevent the sealer from adhering to the asphalt surface. Additionally, it is recommended to wash the area and remove any grease or oils from the surface.

This will allow the new layer of sealer to bind better with the asphalt surface, providing an additional layer of protection. Any vehicles or other items that are left on the asphalt should be removed as well, to avoid any mishaps during the application process. The area that will be sealed should be closed off to vehicular and pedestrian traffic for 24 hours prior to and during the application of the seal coat. Sprinkler systems should be turned off as well, to avoid contaminating the area with water.

The professional pavement contractor will utilize a variety of cleaning equipment, including blowers and rotary brooms to ensure the area is free from any dirt or debris. They will also use a hot rubberized crack filling product to treat any existing linear cracks in the asphalt surface.

Once the area has been properly prepared, the pavement contractor will set up a large tent to contain the area they are working on. The barrels of sealer will be staged on the surface in a way that will give each area equal coverage. Generally, two applications will be needed to achieve an even coating of the sealer.

The temperature and weather conditions must be perfect for successful sealcoating. The temperatures must be above 50 degrees and there must be no chance of rain for 24 hours before and during the application of the seal coat.


The asphalt used to build roadways, parking lots and driveways deteriorates quickly when not properly maintained. Sealcoating protects pavement against UV rays, heavy rain and the damage caused by vehicles. The slick coating also slows down the melting of snow and ice, making driving conditions much safer.

The process of sealcoating is intensive and must be performed under the right conditions. For starters, the pavement must be clean and dry. If the surface has oil spots, they must be treated with a special primer and allowed to dry completely before proceeding. All traffic must be blocked off of the area, and signs must be posted warning pedestrians to avoid the work area. All sprinkler systems must be turned off for the duration of the project as well.

During the application process, workers spread the sealer on the pavement with a spray application or a squeegee. It is important to use a high quality material, as low-quality sealants will only provide limited protection for the pavement. A squeegee is preferred as it allows the worker to cover larger areas more efficiently than a sprayer, which can require multiple passes over the same area. In addition, a squeegee will leave behind a smoother surface with less chance of flaking or bubbling.

A sealcoat is a blend of liquid asphalt binder, sand and other fillers, additives and water. The liquid asphalt binders are made from either refined coal tar or bitumen and help to keep the other materials together. The sand provides texture and bulk, while the other fillers and additives add durability. The water satisfies the “water demand” of the mixture and helps to make it fluid enough for easy application.

Coal tar sealants are considered toxic and have been known to cause cancer and other health issues. They can also cause a number of environmental problems, such as polluting waterways and leaching into groundwater and soils. Because of this, many states have banned the use of coal tar sealants. Other types of sealants are available, including polyurethane and petroleum-based products.

The most common type of sealcoating is based on refined coal tar. This has been found to be the most effective at maintaining the integrity of asphalt pavements and preventing cracks. Using this product regularly can extend the life of a blacktop surface by up to 20 years, saving the property owner money on costly repairs and maintenance.


Sealcoating can be a cost-effective solution for many different pavement areas such as commercial parking lots, walkways, patios, and driveways. The process involves applying a liquid mixture that contains bituminous or acrylic-based liquids, water silica sand, polymer additives, and fillers. It can protect a paved surface from damage caused by oil, fuel and chemical spills, as well as provide flexibility to resist the pressure of vehicular traffic.

The mixture must be thoroughly mixed and allowed to dry before it’s ready for use. The ideal weather conditions for a successful project include sunny and dry conditions. If rain is expected within 24 hours, our professionals will postpone the project until the area is drier.

Humidity is another factor that determines how long the sealcoating takes to cure. It’s important that the ambient air is able to absorb and accommodate the released water from the sealcoat film. This will help the coating to dry more quickly. Humidity levels above 90% will slow down the drying time of a sealcoat.

Drying allows the sealcoat to harden and adhere to the underlying pavement surface. It also prevents moisture from seeping beneath the sealcoat and degrading it. This is an essential process to protect the underlying asphalt from further damage and premature failure.

Our professional team is highly aware of the ideal weather and environmental conditions that must be present in order for a thorough curing process to take place. We make every effort to comply with these standards, recognizing that deviations from them can result in poor performance and premature failure of the coating.

If the weather is not perfect for a sealcoating project, our professionals will let you know and recommend a better day to complete the project. We will only apply the material when it is safe to do so, and we will ensure that the paved surface is clean. If the paving surface is covered with dirt, debris, or snow, it will not be able to bond properly. It’s also necessary to block off the area to prevent people or vehicles from navigating over the fresh coat of sealcoat.
