What are some of the main benefits of sealcoating?

Sealcoating asphalt provides several benefits:

Protection from Elements: Sealcoating acts as a barrier against the damaging effects of UV rays, water, oil, and other chemicals. This helps prevent cracks, potholes, and other forms of deterioration.

Extended Lifespan: By protecting the asphalt from oxidation and water penetration, sealcoating can extend the life of the pavement significantly. Regular maintenance, including sealcoating, can double or even triple the lifespan of asphalt surfaces.

Cost Savings: Sealcoating is a relatively inexpensive maintenance procedure compared to repairing or replacing damaged asphalt. Investing in sealcoating can help prevent costly repairs down the line.

Enhanced Appearance: Sealcoating gives asphalt a fresh, black appearance, enhancing the overall aesthetics of the pavement. This can be particularly important for businesses or properties where appearance matters. 

Reduced Maintenance: Sealcoating makes asphalt easier to clean and maintain. It provides a smoother surface, reducing the accumulation of debris and making sweeping and snow removal more efficient. 

Prevention of Oxidation: Asphalt naturally oxidizes over time, causing it to become brittle and prone to cracking. Sealcoating helps prevent this oxidation, preserving the flexibility and integrity of the pavement. 

      Overall, sealcoating is an important part of asphalt maintenance that helps protect your investment, prolong the life of your pavement, and maintain its appearance and functionality.

      Frequently Asked Questions About Sealcoating

      Why are two thin coats of sealcoating better than one thick coat?

      Enhanced Protection: Two thin coats of sealant provide better defense for your surface. Similar to the way paint benefits from multiple thin layers, sealant behaves more effectively when applied thinly. As sealers dry and cure primarily through water evaporation, thin coats lose moisture faster than thick ones. Thick coats tend to retain water, remaining soft for longer periods, which can lead to tracking and premature wear.  

      Traffic Considerations: 

      • For low-traffic areas like residential driveways, one coat may suffice. 
      • In moderate-traffic parking lots, two coats are recommended, with an additional third coat for entrances and exits. 
      • Heavy-traffic zones such as travel lanes require two coats, plus a third for added durability. 

      Scuffing: Some scuffing is typical, particularly within the first month, even with additives. Hot days, especially above 90°F, exacerbate scuffing. To minimize this, avoid sharp turns on newly coated surfaces. 

      Surface Preparation: Properly preparing the surface is crucial. Thoroughly clean the pavement to prevent adhesion issues caused by dirt, oil, gas, or grease. Remember, labor costs for mobilization, cleaning, and surface prep remain consistent regardless of applying one or two coats. 

      Why apply two coats when one looks adequate?

      While appearance matters, the primary goal of sealcoating is to protect and preserve asphalt. A single coat may offer only half the protection and wear out in less than half the time. Using only one coat may necessitate more frequent sealcoating. 

      Why did the sealcoating fail or peel?

      Peeling occurs when sealcoating fails to bond to oil spots, contaminants like dirt or grease, or oxidized pavements. Before applying sealcoating, ensure thorough cleaning of the pavement surface. Treat oil spots with primer and oxidized surfaces with specialty primer, a thin sealer coat, or tack coat. Other causes of failure include freezing temperatures during curing, tree sap deposits, or applying sealcoating over a hard base. 

      What causes white streaks in sealcoating?

      White streaks may indicate issues with the base, such as limestone coming up through cracks with water. 

      Why does sealcoating dry gray?

      Gray drying results from sealcoating under suboptimal conditions like shade, cool temperatures, or high humidity. This is usually temporary and can be resolved with specialty additives or exposure to sunlight. Persistent gray drying may require consultation with the manufacturer. 

      Why does sealcoating wear out faster in traffic lanes, entrances, and exits?

      Higher traffic leads to smoother aggregates in these areas, reducing adhesion. Specialty primers can enhance bonding by penetrating polished aggregates. 

      How soon can I sealcoat a newly laid asphalt pavement?

      Wait 4-6 weeks, allowing light oils to oxidize. Perform a Water Break Free Test: if water sheets out without oily rings or beading, the pavement is ready. 

      What type of striping paints should be used, and when can the lot be striped?

      Prefer water-based traffic striping paints. Wait at least 24 hours after the final sealcoating coat before striping. 

      What is a mix design?

      A mix design is a formulation of sealcoating concentrate with recommended water, sand, and additives. These are provided by manufacturers based on traffic, pavement condition, and age. 

      How much water can I use?

      Follow manufacturers’ recommendations, typically 25-30 gallons per 100 gallons of sealcoating. Higher percentages are advised for designs with additives or more sand. 

      Why should we use sand?

      Sand adds traction and provides a uniform textured appearance to the surface, reducing glare.
