Asphalt Sealcoat

A worker uses a broom to apply a dark layer of sealcoat.Asphalt sealer adds a protective layer to your project to keep it firm, attractive, and functional for years to come. Things like ultraviolet radiation, oil, ice, rain, and even salt can all present problems for your asphalt, but a well applied sealcoat can prevent all of this by creating a strong barrier.

Though coal tar was the original pavement sealer, it presents several problems because  of its flammability and high toxicity. Since the 1980’s, developers have preferred asphalt emulsion sealcoat,  a more modern, non toxic approach that improves on the aesthetics of the asphalt, typically having a deep black matte finish. Unlike coal tar, asphalt sealcoat isn’t flammable, is environmentally friendly and–because its chemical makeup is more similar to your asphalt–bonds to the material efficiently. A good bond allows the seal to expand and contract with the asphalt as temperatures rise and fall. That elasticity also helps the coat last longer.

Sealcoating is also much cheaper than being forced to replace asphalt. If you apply a good sealcoat you’ll keep your asphalt safe from chemical spills and the elements while also making it easier to clean and maintain. We offer only the highest quality sealants and are more than happy to provide you with advice on your project. Please contact us with any questions you may have about the product or the application process.

To get you started, here are a few tips for applying a nice sealcoat to your asphalt:

  1. Make sure that you clear traffic in the area for about 24-48 hours so that the sealer can set.
  2. These projects are best suited for summer months because the temperature outside must be at least 60°F within a day of applying the sealcoat.
  3. Do not apply sealcoat if it has rained or will rain within 48 hours.
  4. If you are in an area that has a thick morning dew, try to be finished applying by 3pm to prevent any runoff because of the moisture.
  5. It is better to apply two thin coats instead of just a thick one. Two thin coats allow for even drying and a more attractive finish.
  6. Don’t apply sealcoat to a driveway with a slope of more than 20°, otherwise the sealant will not go on smooth and even.
  7. Finally, if you’ve recently made repairs to your asphalt, those repairs need at least six months to cure before you can apply a sealcoat.
