The Sealcoating Process: A Step-by-Step Guide

Thinking about giving your asphalt driveway or parking lot a fresh, protective sealcoat? Understanding the process can help you decide whether to tackle it yourself (DIY) or hire a professional. Here’s a breakdown of the typical steps involved in sealcoating:


Preparation (DIY or Professional)

  1. Clear the Area: Remove all vehicles and furniture from the surface to be sealed.
  2. Edge Trimming: A power edger or shovel can be used to create a clean edge between the pavement and surrounding areas like lawns or flowerbeds.
  3. Cleaning is Crucial: Dirt, oil, and loose debris can prevent proper adhesion of the sealant. Use a broom, leaf blower, and possibly a degreaser for oil stains (consult a professional for proper application) to ensure a clean surface.
  4. Crack Repair (Optional for DIY, Recommended for Professionals): Cracks wider than ¼ inch should be addressed to prevent water infiltration and further damage. Professionals use specialized crack fillers that flex with temperature changes and provide long-lasting repair.

Sealcoating Application (Professional Recommended)

  1. Choosing the Right Sealer: Professional contractors can assess your pavement condition and recommend the most appropriate sealer type and application method.
  2. Weather Matters: Sealcoating is best done on dry days with moderate temperatures (avoid very hot or cold days). Professionals monitor weather conditions to ensure optimal results.
  3. Application: For a uniform, high-quality application, professionals use spray equipment that ensures even coverage and minimizes the risk of missed spots or excessive pooling.
  4. Squeegee and Edges: Hand squeegees ensure a smooth finish along edges and tight spots, while professionals take extra care to create clean lines and a polished look.
  5. Curing Time: Allow the sealcoat to cure completely according to the manufacturer’s instructions. Professionals will advise on appropriate timeframe for using the sealed surface.

DIY vs. Professional Sealcoating

While a DIY approach might seem cost-effective initially, here are some advantages of hiring a professional sealcoating company:

  • Expertise and Experience: Professionals possess the knowledge and experience to assess your pavement condition, recommend the right materials, and apply the sealant flawlessly.
  • Proper Equipment: They have access to specialized equipment for cleaning, crack repair, and application, ensuring a high-quality, long-lasting sealcoat.
  • Safety Considerations: Handling hot sealcoat and maneuvering heavy equipment can pose safety risks. Professionals prioritize safety measures and are trained for proper handling.
  • Time Efficiency: Professionals can complete the job efficiently, minimizing disruption to your daily routine.
  • Warranty and Insurance: Many professional contractors offer warranties on their work and carry liability insurance, providing peace of mind.
