Why Crack Filling Matters

Cracks in asphalt are more than just an eyesore — they allow water to seep beneath the surface, which can lead to potholes, erosion, and costly repairs. Filling these cracks promptly prevents moisture infiltration and protects the base materials. Companies like Capital Parking Lot Line Painting emphasize crack filling as an essential step in any parking lot maintenance plan.

Factors Affecting the Best Time for Crack Filling

Several environmental and seasonal factors impact when you should fill asphalt cracks. These include temperature, moisture levels, and weather stability.

Temperature Considerations

Asphalt needs to be warm and dry for crack filling products to adhere properly. Ideal temperatures are generally between 10°C and 25°C (50°F to 77°F). In Greater Sudbury, this means the best window is typically late spring through early fall.

Moisture and Weather Stability

Dry conditions are critical. Filling cracks during or right after rain can trap moisture underneath the sealant, leading to poor adhesion and early failure. Calm weather without sudden temperature drops also ensures the filler cures properly.

Recommended Seasons for Crack Filling in Greater Sudbury

Given Sudbury’s climate, here’s a breakdown of the seasons and their suitability for asphalt crack filling:

• Spring: Late spring (May and June) is excellent once the frost has melted and the ground is dry.
• Summer: Summer offers warm, dry conditions perfect for crack filling, but it’s important to avoid rainy days.
• Fall: Early fall can still be suitable, but as temperatures drop, it becomes less ideal.
• Winter: Not recommended due to freezing temperatures and snow.
• Winter Thaw Periods: Even during brief warm spells, moisture and cold ground can cause issues.

Steps to Proper Crack Filling

Whether you’re hiring a professional or tackling the job yourself, these steps ensure a successful crack repair:

• Clean the cracks: Remove debris, vegetation, and moisture.
• Dry the area: Ensure the cracks are completely dry before filling.
• Apply the crack filler: Use a high-quality, flexible sealant suitable for asphalt.
• Smooth the surface: Level the filler flush with the surrounding pavement.
• Cure time: Allow proper drying time before opening the area to traffic.

Common Mistakes to Avoid When Filling Asphalt Cracks

• Filling cracks during cold or wet weather.
• Skipping the cleaning step, leaving debris inside cracks.
• Using low-quality or inappropriate filler materials.
• Not allowing sufficient curing time before traffic exposure.
• Ignoring small cracks until they worsen.
