Why Asphalt Sealing Matters

Asphalt calculator surfaces degrade over time due to sun exposure, rain, oil spills, and traffic load. Applying a protective sealer:

• Extends pavement lifespan
• Prevents cracks and potholes
• Improves surface appearance
• Reduces long-term repair costs

Proper estimation ensures you don’t underbuy or overbuy materials.

How It Works

This estimation is based on a simple formula:

Sealer Required = Surface Area ÷ Coverage Rate

Typical coverage rate:

• 1 gallon covers 150 to 300 sq ft (depending on product quality and surface condition)
