Why Sealcoating Is Essential for Pavement Longevity
When it comes to preserving the life and beauty of your asphalt pavement, Sealcoating is the superhero in Dominion Paving & Sealing’s toolkit. Sealcoating acts as a long-term investment in your pavement’s durability. By forming a protective layer over asphalt, it prevents premature cracking, raveling, and surface erosion caused by environmental factors like sun, rain, and chemicals. Regular sealcoating can extend the life of asphalt by several years, saving time and money on costly repairs. Let’s dive into what makes sealcoating a vital step in pavement maintenance:
The Purpose of Sealcoating
Sealcoating serves as a robust shield for existing, sound asphalt pavement. It stands guard against a multitude of potential damages, including moisture penetration, surface water damage, UV rays’ oxidation, winter’s freeze/thaw cycle, and harmful chemical spills. It acts as a barrier, preventing surface raveling and check cracking.
Materials and Equipment Matter
Our sealcoating products include a specially formulated rubberized, asphalt resin base coating. This impervious sealer deflects the harmful effects of gasoline, oils, and aliphatic solvents that can wreak havoc on asphalt surfaces. The inclusion of mineral aggregate ensures durability, providing a clean and dry silica sand-free surface. Additionally, our asphalt paving contractors use top-of-the-line equipment to apply these products to ensure a consistent and high-quality finish to your pavement.
Sealcoating comes in different formulations depending on the type of asphalt and traffic demands. Common types include coal-tar emulsion, asphalt-based emulsion, and polymer-modified coatings. Each has its advantages – some resist oil and gasoline better, while others provide superior flexibility and UV protection. Choosing the right product ensures optimal protection for your pavement.
Surface Preparation
Proper preparation is crucial for the sealcoat to bond effectively. Start by repairing any cracks or potholes, clean the surface of debris, and ensure it is completely dry. This step prevents issues like peeling or uneven coverage, and ensures that the protective layer adheres uniformly for maximum effectiveness. Before applying the protective seal, we ensure meticulous surface preparation. All vegetation is removed, and surfaces are cleaned thoroughly to eliminate foreign debris like dirt, silt, gravel, and leaves. Oil spots are treated with an acrylic oil spot primer to enhance sealer adhesion and prevent bleeding.
Application
Our skilled team applies two coats of asphalt resin emulsion, meeting stringent material specifications. The protective coating is applied at a total minimum rate of 0.17 gallons per square yard, ensuring comprehensive coverage. We conduct the application in dry weather, with atmospheric temperatures above 50⁰F and anticipation of remaining so for 48 hours after application.
Drying and Exclusion Period
Adequate drying time is allowed between the two coats to ensure a tack-free surface. After the second application, we exclude all traffic for a minimum of 24 hours, allowing the coating to dry thoroughly. This exclusion period guarantees optimal protection and longevity.
Tips for Applying Sealcoat Correctly
Use the recommended coverage: Apply the proper amount of sealcoat per square yard to ensure even protection.
Allow each coat to dry: Let the first coat dry completely before applying the second to prevent tackiness and uneven surfaces.
Avoid bad weather: Do not apply sealcoat in cold, wet, or damp conditions, as this can reduce adhesion and durability.
Use proper tools and equipment: Employ professional-grade tools to achieve a smooth, uniform finish.
Follow best practices: Adhering to these tips ensures a strong, long-lasting protective layer on your asphalt.
