How to Get Tar Off a Cement Driveway

Save

Tar is used on a cement driveway to act as a sealer and to fill in cracks in the concrete. Because of wear and tear from cars and the weather, a driveway takes quite a beating. At times you will remove old tar in order to refurbish or repair your driveway. Removing tar is not easy. In addition to being sticky, the tar will penetrate into the surface of the cement because concrete is porous. Try some simple solutions for removing tar before buying expensive tar-removing products or calling in a professional.

Things You'll Need

  • Shovel
  • Screwdriver
  • Power washer
  • Sandblaster
  • Mineral spirits
  • Scrub brush
  • Paint thinner
  • Gasoline
  • Tar-removing product
  • Scrape off as much tar as you can with an old shovel or other flat-edged tool.

  • Remove as much tar as possible with a power washer.

  • Remove the tar by sandblasting your concrete driveway.
