What You Need to Know About Sealcoating for Long-Lasting Pavement

1. Twin State Paving - Expert Paving Service in NH & VT What You Need to Know About Sealcoating for Long-Lasting Pavement When it comes to preserving your pavement and maximizing its lifespan, sealcoating is one of the most effective and affordable solutions available. Whether you're a homeowner with a driveway or a business managing a commercial parking lot, routine asphalt sealing protects your investment, improves aesthetics, and significantly reduces long-term repair costs. At Twin State Paving, one of the leading Paving Contractors Upper Valley NH , we specialize in high-quality sealcoating and pavement maintenance services designed to keep your surfaces looking and performing their best. What Is Sealcoating? Sealcoating is the process of applying a liquid protective coating over asphalt pavement. This sealant forms a barrier that shields the surface from harmful elements such as water, UV rays, oil spills, and harsh chemicals. Without this protection, asphalt can quickly become brittle, cracked, and faded due to oxidation and weather exposure. By regularly sealcoating, you extend the life of your asphalt and maintain a smooth, dark, attractive finish that enhances both safety and curb appeal. The Science Behind Sealcoating Asphalt is made of a combination of aggregate (stone, sand, and gravel) and a binder, usually bitumen. Over time, the binder begins to break down when exposed to oxygen and sunlight—a

This weakens the pavement and causes it to become brittle, making it more susceptible to cracking and other forms of damage. Sealcoating acts as a shield against this natural degradation. It slows oxidation, repels water, and helps your pavement retain its elasticity and strength. Additionally, it protects against surface erosion from traffic and environmental wear. Key Benefits of Sealcoating 1. Extends Pavement Life Sealcoating can extend the life of your pavement by up to 30%. When applied properly, it helps preserve the structural integrity of the asphalt and prevents small issues from becoming big problems. 2. Enhances Aesthetic Appeal A freshly sealed surface has a rich black finish that improves the overall look of your property. Whether you own a home, a retail business, or an apartment complex, curb appeal matters—and sealcoating delivers. 3. Protects Against the Elements Sunlight, water, snow, and ice are major culprits in asphalt deterioration. Sealcoating offers a protective layer that resists penetration from these elements, particularly during harsh New England winters. 4. Minimizes Repair Costs Addressing cracks and potholes after they form can be costly. Sealcoating prevents this damage in the first place, making it a smart, budget-friendly investment in long-term pavement maintenance. 5. Improves Safety Sealcoating smooths out the surface, which can reduce trip hazards and improve vehicle traction. Clear striping on a dark surface also enhances visibility in parking lots. How Often Should You Sealcoat? In general, you should sealcoat your asphalt every 2 to 3 years, depending on usage and climate conditions.

Twin State Paving - Expert Paving Service in NH & VT ● Residential Driveways: Every 3 years is typical if the surface experiences moderate vehicle traffic. ● Commercial Parking Lots: Due to heavier use, these surfaces may benefit from sealcoating every 2 years. It’s also crucial not to over-seal, as too many layers can lead to surface cracking and flaking. An experienced contractor like Twin State Paving, among the top asphalt companies New Hampshire , can evaluate your pavement and recommend the right schedule. When Is the Best Time to Sealcoat? Sealcoating requires warm, dry weather for proper curing. In the Northeast, the ideal sealcoating season runs from late spring to early fall, when temperatures consistently stay above 50°F and rain is minimal. Preparing Your Pavement for Sealcoating Before applying a sealcoat, the surface must be thoroughly cleaned and prepped: ● Debris Removal: Sweep or blow off leaves, dirt, and gravel. ● Crack Filling: Fill any existing cracks to prevent moisture intrusion. ● Oil Spot Treatment: Clean and prime areas with oil stains so the sealant adheres properly. At Twin State Paving, recognized among trusted paving contractors in Upper Valley NH, we ensure your surface is fully prepped for long-lasting results. Types of Sealcoating Materials There are several types of sealcoating products available, each with its own advantages: ● Coal Tar Emulsion: Highly durable and resistant to chemicals and weathering. ● Asphalt Emulsion: More environmentally friendly and low-odor, but slightly less resistant to oil and gas. ● Acrylic Sealer: Often used for specialty applications, offering bright color options and high durability.
