When Is the Right Time of Year to Fill Cracks in Asphalt?

Maintaining your asphalt surfaces is crucial for ensuring safety and prolonging their lifespan. One important aspect of this maintenance is filling cracks, which can prevent further deterioration and save you from costly repairs down the line. But when is the right time of year to tackle this task? In this blog post, we'll explore the optimal conditions for crack filling and provide tips from the experts at Capital Parking Lot Line Painting.

Asphalt crack filling

The Ideal Temperature Range

The temperature plays a significant role in determining the best time for asphalt crack filling. Most professionals, including the team at Capital Parking Lot Line Painting in London, recommend tackling this task when the ambient temperature is between 50°F (10°C) and 80°F (27°C). Within this range, the asphalt is warm enough for the crack filler to adhere properly, but not too hot that it dries out or becomes difficult to work with.

Why Temperature Matters

  • Colder temperatures can cause the crack filler to harden prematurely, leading to poor adhesion and potential cracking or crumbling.
  • Excessively hot temperatures can cause the filler to dry out too quickly, resulting in shrinkage and compromising the seal.
  • The ideal temperature range ensures that the filler remains pliable and bonds effectively with the asphalt surface.

The Best Seasons for Crack Filling

Based on the temperature guidelines, the spring and fall seasons typically offer the most favorable conditions for asphalt crack filling in London and many other regions of Ontario. During these transitional periods, the weather is generally mild, with temperatures falling within the recommended range.

However, it's essential to monitor the forecast and avoid scheduling crack filling during periods of heavy rain or extreme temperature fluctuations. Moisture can interfere with the curing process, while sudden temperature changes can compromise the integrity of the filler.

"At Capital Parking Lot Line Painting, we always recommend scheduling your asphalt crack filling during the spring or fall months," says John Smith, the company's lead technician. "These seasons offer the most consistent and ideal temperatures for ensuring a proper cure and long-lasting results."

Preparing for Crack Filling

Regardless of the time of year, proper preparation is essential for successful asphalt crack filling. Here are some key steps to follow:

  1. Clean the cracks thoroughly, removing any debris, vegetation, or loose material.
  2. Ensure the surface is dry and free from moisture.
  3. Apply a tack coat or primer if recommended by the manufacturer.
  4. Follow the instructions for applying the crack filler carefully, ensuring proper coverage and depth.
  5. Allow sufficient curing time before reopening the area to traffic.
