When it comes to maintaining curb appeal for your property, asphalt is a top priority. After all, having an attractive driveway or parking lot is essential for making a good impression. Whether you’re trying to attract customers or make your property look nice, seal coating and patching are the two most common ways of restoring damaged asphalt.

You should contact a professional asphalt paving contractor before choosing either of the asphalt maintenance processes. This ensures you’re fully aware of your options.

To give you a better idea, let’s discuss the critical differences between the two methods so you can decide which suits your needs.

What Is Asphalt Seal coating?

Asphalt seal coating applies a thin layer of liquid asphalt over an existing driveway. This protects the asphalt from water damage, sun exposure, and other elements that can accelerate its deterioration. The seal coat helps to prevent further cracking and potholes on the road’s surface. To apply this process, you’ll need to use specialized equipment like a squeegee or broom and a thinner mixture of asphalt emulsion.

What’s the most appropriate time of the year to schedule a seal coating project? Here’s the answer.

What Is Asphalt Patching?

Asphalt patching involves repairing damaged areas by filling them with new asphalt material. It involves more preparation than seal coating. The holes must be filled, edges must be leveled off, and the entire area must be thoroughly cleaned before any repairs are made. Additionally, you’ll need tools such as a chisel, rake, hammer, and shovel to help shape the asphalt.

How Do They Differ?

The scope of work is the main difference between asphalt seal coating and patching. Asphalt seal coating works to coat and protect the entire surface while patching only repairs damaged areas. Seal coating also prevents oxidation, which causes asphalt surfaces to turn gray and deteriorate over time.

Moreover, seal coating also helps improve the appearance of asphalt surfaces. Sealants come in various colors and finishes, such as matte or glossy, allowing you to customize your asphalt’s aesthetic.

Things To Consider Before Choosing Either One

Budget

Budget is a significant factor before choosing between asphalt seal coating and patching. Seal coating is more expensive than patching but provides long-term protection for your pavement.

Surface condition

Another thing to consider is the condition of the surface. Asphalt patching will be the better option if it’s heavily cracked or damaged in certain areas, as seal coating may not provide complete coverage. Assess your pavement condition before deciding which asphalt maintenance solution is best for you.

Age of the pavement

The pavement’s age should also be considered, as asphalt seal coating is only suitable for newer asphalt surfaces. If your asphalt surface is aged and degraded, you should opt for asphalt patching instead.

Equipment involved

Asphalt seal coating requires specialized equipment, such as a squeegee or sprayer, to apply the material evenly on the surface. On the other hand, asphalt patching uses an infrared heat machine to soften existing asphalt so that new material can be added to fill any cracks or holes.

An asphalt paving contractor can help you determine your surface’s best asphalt maintenance method and provide the necessary equipment to complete the job.

Benefits And Drawbacks of Each Method

Asphalt seal coating is beneficial because it helps protect the surface from damage caused by UV rays and water seepage, increases visibility at night, and improves traction. The downside is that asphalt seal coat material can be slippery when wet and should not be applied in areas with high foot traffic or vehicles.

Asphalt patching repairs any damaged areas quickly and effectively. However, this method requires more intensive labor, making it costlier than asphalt seal coating. It also requires more specialized knowledge to identify and repair any underlying issues correctly.

What Are the Costs Associated with Each Process?

The cost for seal coating an asphalt surface can vary significantly based on the size of the project and additional services such as a crack filling or line striping that may be needed. Generally, it will cost between $0.50 – $3.00 per square foot and could go up to $5 per square foot for larger projects.

Asphalt patching is typically more expensive than seal coating because of the extra time and materials required. It usually costs around $2-$5 per square foot to patch small areas, while it could cost up to $10 per square foot if you have a large area that needs to be patched.

Factors that can influence costs

Influential factors include the size of the project, the material used, and any additional services needed, such as crack filling or line striping. It is essential to evaluate all factors before deciding which maintenance method best suits your needs.

Reasons To Choose a Professional Asphalt Paving Contractor.

Experience

Asphalt paving contractors consist of years of experience in this field. They can advise you on the best decision for your project.

Quality services

A professional asphalt paving contractor will provide quality services and ensure the job is done correctly. Additionally, they use high-quality materials that can last for years.

Warranty

Working with a professional contractor allows you to benefit from their warranty in case of any issues or damages. This is important so you don’t have to pay for additional repairs if something goes wrong during the project.

Conclusion

Asphalt seal coating and patching are effective methods for maintenance projects. However, evaluating the project size, budget, and other influential factors is essential before deciding what best suits your needs. If in doubt, seek advice from a reputable asphalt paving contractor who can recommend the best solution and ensure the job is done correctly.
