Create a Brighter Future

CoolSeal is the only cool pavement sealcoat on the market that offers a fully green alternative to polymer-based coats. Our ultra-high-performance sealcoat is designed to reflect the sun and lower asphalt surface temperatures by  10-20 F  to mitigate heat warming effects and enhance the comfort and well-being of communities.

The Unconvential Power of CoolSeal

CoolSeal asphalt sealcoat, introduced by GuardTop® in the winter of 2016 for the LA Street Services Bureau, revolutionizes urban paving with its ability to combat urban heat warming and stands out from traditional options. Unlike conventional pavements that absorb and radiate heat, CoolSeal reflects sunlight, significantly reducing surface temperatures and lasting twice as long as standard coatings. This durability and effectiveness have established it as a market leader in cool pavement technology, aiding in the fight against climate change. To date, CoolSeal has been applied across hundreds of lane miles in 22 states and 6 countries, demonstrating its commitment to sustainability, community comfort, and health, with proven results.

Put to the Test

Proven to Outperform

CoolSeal distinguishes itself not only through its outstanding performance, significantly reducing street temperatures, but also by its exceptional durability and resource-saving qualities. Demonstrating unparalleled resilience, streets treated with CoolSeal exhibit minimal wear even after several years, outlasting traditional materials. This longevity means fewer applications over time, conserving resources and offering a more sustainable choice for communities.

Reflect, Protect and Preserve

How It Works

Reflective Formula

Coolseal's unique formula, which is made with recycled materials and free of harmful chemicals, is designed to convert solar heat / harmful UV rays into other forms of light, interrupting  heat absorption.

Temperature Reduction

This reflection of sunlight directly reduces the surface temperature of the pavement, often by 10-20 degrees Fahrenheit under certain conditions, making it cooler to the touch and the surrounding area more comfortable.

Urban Warming and Heat Island Mitigation

By lowering pavement temperatures, CoolSeal contributes to reducing ambient temperatures and the urban heat island effect, which is the temperature disparity between urban areas and their rural surroundings.


CoolSeal leverages eco-friendly materials to cut waste and toxic emissions, enhancing community life by cooling the pavements, which extends their life, reduces upkeep costs, and fosters more sustainable urban infrastructure.

Find answers to commonly asked questions about CoolSeal's innovative asphalt sealcoat.

How does CoolSeal by GuardTop work?

It is a water-based asphalt treatment that is applied on top of the existing asphalt pavement. It's made with asphalt, water, an emulsifying agent (soap), mineral fillers, polymers, and recycled materials. It contains no harmful chemicals and is compatible with traditional asphalt.

Does cool pavement look different than traditional asphalt?

Yes, the cool pavement coating is a lighter grayish concrete color. When applied, the material dries to a matte finish. Despite being lighter in color, cool pavement does not result in glare. It also meets or exceeds skid-safety requirements.

How is cool pavement applied?

Cool pavement can be sprayed or applied with a squeegee, just like traditional surface treatments applied to city streets.

What are the benefits of using CoolSeal by GuardTop?

CoolSeal is a high-performance, water-based, asphalt emulsion sealcoat designed to achieve lower surface temperatures through its lighter color and reflectivity. CoolSeal meets Environmental Protection Agency (EPA) and LEED requirements of 33 percent reflectivity and can last longer than conventional sealcoats.

How effective is CoolSeal in reducing heat in urban areas?

CoolSeal reflects 30% more sunlight and lowers surface temperatures by 10-16℉, compared to uncoated asphalt. It can lower surface temperatures by up to 20℉ as compared to black-coat asphalt. It also lowers subsurface temperatures by nearly 5℉, resulting in long-lasting surfaces that reduce maintenance needs and save on costs.

What are the safety benefits of CoolSeal?

Lower surface temperatures can benefit children and animals who are outside on warm days, as well as help vulnerable populations without air conditioning stay cooler on hot summer days. In addition, our sealcoat dries to a light gray matte finish, reducing glare and increasing visibility at night. Finally, asphalt that is kept in good repair by a strong sealcoat like CoolSeal can reduce accidents.

Why are two coats usually applied?

A two-coat application is used to ensure high-quality results. When two coats are applied, any cracks or gaps remaining from the first coat are filled in. The second coat also helps to increase the lifespan of the product and save money.

How does CoolSeal contribute to environmental sustainability?

CoolSeal is manufactured with recycled materials and doesn’t use fossil fuels like tar coal or bitumen. It’s been proven to lower surface temperatures by an average of 12 degrees Fahrenheit during peak afternoon heat, as compared to traditional products. This cooling effect not only creates more comfortable environments, it can help decrease energy demand, which is associated with lower associated air pollution and greenhouse gas emissions. Additionally, when applied correctly, CoolSeal lasts twice as long as conventional sealcoats and increases the longevity of asphalt, thus reducing the cycle of asphalt replacement and waste.

How does CoolSeal differ from traditional asphalt sealcoats?

Conventional polymer-based asphalt sealcoats are created from a blend of coal tar or bitumen, sand, and other fine particles. These dark surfaces absorb heat and energy, causing high surface temperatures and urban heat island effects.
