How to protect your asphalt parking lot from harsh sun?

protect your asphalt parking lot

As the winter comes to an end and spring approaches, days will become sunnier and nights become warmer. With every day passing, the sun becomes harsher and affects ground surfaces such as parking lots. The sun’s harmful UVA and UVB rays damage the parking lot materials, especially asphalt in the same way as they do to your skin. Asphalt is an excellent material for parking lots, but without proper maintenance and care, it won’t withstand the harsh sunlight. It can start cracking and disintegrating due to the sun exposure, excessive use, uneven installation, or combination of all these factors. The best way to protect asphalt parking lots is by applying a new seal every two years. Seal coating the parking lots and other asphalt surfaces are one of the common asphalt services that pavement companies get requests for.

In this article, we will talk about some of the best sealants to protect your asphalt parking lot this summer.


Coal Tar Emulsion

Coal tar emulsion is the number one choice for seal coating asphalt surfaces. It is the most durable coating option and provides the most protection against sun’s UV rays and water. One of the major disadvantages of coal tar emulsion is the color. It naturally has a gray color, not as dark black as asphalt. So, if you coat your asphalt lot with coal tar emulsion, the natural black color will be replaced with the gray tint. And as this emulsion will wear-off, it will leave behind an uneven-looking asphalt surface.


Microsurfacing is a protective seal coat which extends the life of the pavement. It is a thin, tough layer of asphalt emulsion blended with finely crushed stone for traction. The process uses polymers and residual content as well as better quality aggregate to enhance the efficiency of your parking lot as well as create an appealing surface.


Tire Rubber Modified Surface Seal (TRMSS) protects and extends your pavement’s life by restoring essential surface oils that get depleted over time. This seal coating even secures loose aggregates and prevents the asphalt surface from damage-causing elements such as oxidation, harsh weather, harmful UV rays, and continuous traffic. This seal is easy to apply, and a single coat process eliminates the need for multiple applications. All these factors make TRMSS an excellent protection for asphalt parking lots.

Acrylic Polymer Sealant

Using acrylic for seal coating asphalt is the most expensive choice. It is durable, UV resistant, weather resistant, and classified as environmentally friendly. It is available in different colors, which makes it a popular choice for customized parking lots.

While it may be tempting to seal coat on your own, seal coating requires expensive equipment, products, and experience mastering the task. It is better to opt for professional asphalt services.

Apart from coating the parking lots with these sealants, you must consider scheduling a professional inspection annually. Through the inspection process, the paving contractors can identify problems and fix small imperfections before they become serious potholes and cracks. Schedule your professional inspection today if your parking lot needs attention.
