Sealcoating is the best way to protect and beautify asphalt surfaces. Sealcoating extends the life of asphalt by protecting it from the damaging effects of water, sun, salt, fuel, and oil. Deal Asphalt uses a sealer made from a coal tar emulsion that is not soluble in oil or gas.

You should sealcoat new asphalt as soon as it begins to turn gray or 90 days after installation, at the latest. After the first sealcoating (Driveway or Parking Lot), asphalt should be re-sealcoated every three to four years depending on condition. Without sealcoating aging asphalt will crack and break down more quickly. Water penetration and oxidation erode the stone base beneath the asphalt and produce potholes—sometimes big, dangerous ones



What happens to asphalt?

Standard asphalt is very susceptible to natural and man made elements.

Natural Elements are

  • Sun
  • Wind
  • Rain, Snow and
  • Ice

These elements cause oxidation to the pavement, drying out the asphalt.

Man Made Elements are

  • Fuel
  • Oil
  • Antifreeze
  • Salts

These elements break down the oils and cohesive properties in the asphalt.

As new asphalt age's small open cracks are formed between the asphalt, from oxidation and rain. These small cracks permit water, salt, fuel, oil, and ultraviolet rays to penetrate into the base leading to greater damage, unless repaired properly. Water is said to be the most damaging agent to asphalt. This leads to larger cracks, eventually collapsing into the eroded voids, causing potholes. Alligator cracks and potholes should be cut with a saw, and replace before sealing


Benefits of Seal Coating

  • Protects your investment. Extends the life of your asphalt, saving you money in the long run. Sealcoating beautifies and enhances your driveway or parking lot, giving it a dark black color to the pavement making it look and wear like new. A dark black parking lot offers a positive image of how clean a company, or residential home is.


  • Sealcoating slows down oxidation and water penetration. Blocks out natural elements such as, sun, wind, rain, snow, and ice.


  • Sealcoating resist harmful man made element spills such as fuel, antifreeze, oil, and salt. Our sealer is made from a coal tar emulsion that isn’t soluble in oil or gas.


  • Sealcoating fills small voids in asphalt reducing exposure to oxygen and water and extending pavement life

How often should you seal coat asphalt?

You should begin sealcoating your new asphalt as soon as it begins to turn grey or 90 days after installation. If you have already sealcoated your asphalt in the past, it is recommended to re-apply sealer every 3 to 4 years depending on the wear of the previous applications.
