Why Gilsonite Sealer is the Ultimate Pavement Solution

Unveiling the superior performance of Gilsonite Sealer, the ultimate pavement solution to safeguard and prolong the life of your surfaces. With its unique composition and remarkable properties, this sealer offers unparalleled protection against the harshest conditions, making it the go-to choice for pavement preservation and maintenance.

Gilsonite sealer stands out in the realm of pavement preservation due to its unparalleled durability and protective qualities. Derived from natural asphalt, this material brings the robustness of gilsonite, a naturally occurring, resinous hydrocarbon, to the forefront of pavement maintenance. When applied to asphalt, it penetrates the surface, filling in the microscopic gaps and cracks, thereby fortifying the pavement from within. This process not only enhances the asphalt’s resistance to wear and tear but also significantly improves its resilience against water damage, UV rays, and chemical spills. The sealer acts as a barrier, shielding the pavement from the elements, while also imparting a rich, dark color that rejuvenates the appearance of the asphalt. Furthermore, its eco-friendly nature ensures that you are making a sustainable choice, aligning with the growing global emphasis on environmentally responsible construction practices.

Optimizing Pavement Lifespan with Gilsonite Sealer

Embracing gilsonite sealer for asphalt maintenance translates to an investment in longevity and performance. Its applications span various types of pavement projects, from residential driveways to commercial parking lots and even airport runways. The versatility of this sealer lies in its ability to adapt to different asphalt conditions, providing a tailored solution that addresses the specific needs of each project. By forming a robust, protective layer on the asphalt surface, it drastically reduces the need for frequent repairs and resurfacing, leading to significant cost savings in the long run. Furthermore, its ease of application ensures that the maintenance process is straightforward, minimizing downtime and disruption. By choosing gilsonite sealer, you are opting for a solution that not only safeguards your pavement but also enhances its aesthetic appeal, contributing to the overall value and functionality of your property.

The Science of Gilsonite

Gilsonite is a naturally occurring hydrocarbon resin derived from the Uinta Formation in Utah, USA. It is a black, shiny, and brittle solid that is soluble in various organic solvents. Gilsonite is also known as uintaite, asphaltum, or natural bitumen. This unique material possesses excellent waterproofing and binding properties, making it an ideal component in the production of gilsonite-based sealers.

Gilsonite Sealer Formulation

A gilsonite sealer is formulated by blending gilsonite with a compatible carrier solvent, such as mineral spirits, to create a fluid product. This blend is then combined with various additives, including surfactants, stabilizers, and pigments, to enhance its performance and ease of application. The result is a versatile, long-lasting sealer that provides excellent protection and durability for asphalt surfaces.

Benefits of Using Gilsonite Sealer

Enhanced Durability

Gilsonite sealers offer superior durability compared to traditional coal tar or asphalt emulsion sealers. They create a tough, flexible, and chemical-resistant barrier that protects against water penetration, oxidation, and damage from ultraviolet rays. This improved durability can significantly extend the lifespan of your pavement, reducing the need for costly repairs and replacements.


Gilsonite is a natural, non-toxic material, making gilsonite sealers an eco-friendly option for pavement maintenance. Unlike coal tar sealers, which contain polycyclic aromatic hydrocarbons (PAHs), gilsonite sealers are free of these harmful compounds. This environmentally responsible choice not only benefits the planet but also contributes to a healthier environment for humans and wildlife.

Easy Application

Gilsonite sealers can be applied using standard pavement maintenance equipment, such as spray systems or squeegees. Their fast-drying properties and low viscosity ensure a smooth, even application, resulting in a professional-looking finish. Moreover, gilsonite sealers are less prone to tracking or sticking, making them easier to work with than other sealing products.

Improved Aesthetics

Asphalt surfaces treated with gilsonite sealer exhibit a deep, rich black color that enhances the overall appearance of the pavement. This attractive finish not only improves curb appeal but also helps to restore the original look of aged or faded asphalt.

Choosing the Right Gilsonite Sealer

When selecting a gilsonite sealer for your pavement project, consider the following factors:

Performance Requirements

Different gilsonite sealers offer varying levels of performance, depending on their formulation. Consider the specific needs of your pavement, such as resistance to weathering, chemicals, or heavy traffic, to determine the most suitable product.


Ensure the gilsonite sealer you choose is compatible with your existing asphalt surface. Some sealers may not adhere well to certain types of asphalt or may cause compatibility issues with previously applied coatings.

Application Conditions

Consider the environmental and application conditions, such as temperature and humidity, when selecting a gilsonite sealer. Some products may require specific conditions for optimal performance, while others may be more versatile and suitable for a broader range of situations.

Cost and Coverage

Evaluate the cost and coverage rate of different gilsonite sealers to determine the most cost-effective solution for your project. While some products may have a lower upfront cost, they may require more frequent applications or provide less coverage, leading to higher long-term expenses.

Regulatory Compliance

Ensure that the gilsonite sealer you choose complies with local and federal regulations, especially concerning environmental and safety requirements. Some regions may have specific restrictions on the use of certain sealing products, so it is essential to verify that your chosen sealer meets these guidelines.

Application Tips for Gilsonite Sealer

To achieve the best results when applying gilsonite sealer, follow these tips:

Surface Preparation

Proper surface preparation is crucial for the successful application of gilsonite sealer. Clean the asphalt surface thoroughly, removing dirt, debris, oil stains, and any loose or damaged material. Repair any cracks or potholes, and ensure the surface is dry before applying the sealer.

Mixing and Storage

Ensure the gilsonite sealer is well-mixed before application, as the components may separate during storage. Follow the manufacturer’s recommendations for mixing and storage to maintain the product’s integrity and performance.

Weather Conditions

Choose a day with optimal weather conditions for applying the gilsonite sealer. Ideally, the temperature should be above 50°F (10°C), and there should be no rain in the forecast for at least 24 hours after application. High humidity and extremely hot temperatures may affect the sealer’s performance and drying time.

Application Technique

Apply the gilsonite sealer using the appropriate technique and equipment, such as a squeegee or spray system. Follow the manufacturer’s guidelines for application rates and methods to ensure proper coverage and optimal performance.

Curing Time

Allow adequate curing time for the gilsonite sealer to dry and harden before allowing traffic on the pavement. The recommended curing time may vary depending on the specific product and environmental conditions, so consult the manufacturer’s instructions for the best results.


Regular maintenance, such as sweeping and cleaning, can help prolong the life of your gilsonite-sealed pavement. Periodic reapplication of the sealer, typically every 3-5 years, can also help maintain its protective and aesthetic properties.


Gilsonite sealer is a durable and eco-friendly solution for protecting and preserving asphalt surfaces. Its unique properties offer numerous benefits, including enhanced durability, easy application, and improved aesthetics. By understanding the science behind gilsonite sealer, selecting the right product for your needs, and following best practices for application, you can ensure a long-lasting and high-performing pavement.
