Asphalt driveway seal coating

Key Benefits

  • Protects a major investment
  • Extends pavement life
  • Adds value through good appearance
  • Helps the sun melt winter snow & ice
  • Addition of sand grit to sealer can aid traction

Asphalt driveway sealing in the northern US is best performed during late spring, summer, and early fall. Taking advantage of a couple dry days, with no rain in the forecast, will help ensure a successful project. Early fall is often preferred since temperatures are a bit cooler, slowing down drying time a bit, and making the application a little easier to apply.


We suggest completing your sealing project before the advent of cold weather -- an average cut-off date of September 30 in Pennsylvania is usually a good average. Leaf drop can be an annoyance and slow your sealing work, so it is best to complete your asphalt sealing project before any significant leaf drop from trees begins.

Brushing on a top quality blacktop sealer will improve the appearance of your driveway and help protect it against oily vehicle drips and the elements. Asphalt sealers that aren't too glossy (like the one shown below) provide better traction, but multiple coats of sealer over the years will eventually make any blacktop driveway more slippery since it is so much smoother. To aid traction, fine sand can be added to your mix, or applied over top of the sealer while it is still wet. One commercial product that is often used is a fine-textured black grit called "Black Beauty" which comes as a bagged product.
