Seal Coating FAQs: The 6 Most Often Asked Questions

Seal Coating FAQs: The 6 Most Often Asked Questions

1. Why sealcoat pavement driveways and parking lots?

Asphalt is made up of stones and fine sands; asphalt cement acts as the glue to hold them together, further providing the pavement with the rich, black color. Unfortunately, over time, the binder begins to oxidize from exposure to the sun, rain, snow, and other elements, thereby causing the pavement to fade to gray, and crack from vehicle traffic. Additionally, exposure to motor oil leaks, landscaping, and household chemicals degrades the pavement.

Appling seal coating creates a barrier protecting the asphalt from the harmful sun’s UV rays, rain, snow, and harmful chemicals.

2. How long does seal coating last?

Seal coating can last up to three years if your pavement is in great shape, however, older asphalt may need to be resealed annually.

3. How long does it take to dry?

Depending on the humidity exposure to the sun and temperatures. In most cases, you can walk on your pavement within 4 to 8 hours and open it to auto traffic within 24 to 48 hours after seal coating.

4. What causes the most wear and tear to a seal coated asphalt surface?

In the Pennsylvania/New Jersey area, we experience extreme weather conditions; freezing temperatures, snow and the effects snowplowing can have on your pavement, sand, salt, rain/water run-off and the summer heat. All of which can all wreak havoc on asphalt.

5. Can seal coating protect large cracks or little spider cracks in the pavement?

No. Seal coating won’t seal cracks, nor will it smooth out rough asphalt surfaces. Learn more about Crack Sealing and Repairs.

6. When is the best time of year to sealcoat?

Sealcoating must be performed when the temperature is about 50 degrees overnight. This means that the best time to sealcoat is between the months of April and October.
