What Are the Proper Curing Conditions for Sealcoating?

To stay looking their best and withstand Mother Nature, asphalt driveways and parking lots should be sealcoated every few years. This professionally-applied sealant blocks out the elements and prolongs the surface’s lifespan for years to come. This post will cover the factors behind sealcoating curing and how the curing process can affect sealcoating performance in Santa Rosa, CA:

  • Temperature: The sealer shouldn’t be applied unless the pavement temperature is at least 50 degrees and the air temperature is 50 degrees and rising. If the temperature is too low, the asphalt particles won’t soften and form a continuous film over the entire surface. Unfortunately, we run into other problems if the temperature is too high. If the sealer is applied on hot summer days without first cooling the pavement down, the sealer can “bake” onto the asphalt without first forming a protective film.
  • Humidity: Sealcoating applied on very humid days will take longer to cure because the air doesn’t have very much room to absorb the moisture coming from the sealant. Though professionals can work in humid conditions, they need to be mindful and allow longer drying times between layers of sealcoating.
  • Wind velocity: Professionals don’t take the wind into consideration when it comes to drying and curing times for sealcoating. That said, it’s a fact that a slight breeze does help the sealer dry faster.

What happens if sealcoating doesn’t cure properly?

We wouldn’t spend so much time focusing on the ins and outs of sealcoating curing in Santa Rosa, CA if it didn’t have serious consequences. Here’s what can go wrong if the curing process doesn’t go according to plan:

  • Poor performance: The sealer should obviously cover the entire surface to most effectively defend against the elements. If the sealer is applied when it’s too hot or too cold, or if it’s not given enough time to dry, there won’t be adequate coverage. Moisture will get down into the asphalt and basically render the sealcoating useless.
  • Premature failure: Sealcoating is designed to last three years or so before it needs to be reapplied. If the right steps aren’t taken during the sealcoating process, the sealer will stop working before it’s supposed to. This means you’ll need to pay to have it sealcoated again sooner than expected!

What else goes into quality sealcoating?

The weather is obviously important, but it’s not the only thing that determines whether or not a sealcoating job will be a success. The points below also affect the outcome:

  • The right mix: For best results, the sealcoating mix should be uniform in consistency, smooth and free of foreign objects. Our trained professionals know all the right components to put in the mix to ensure it defends your asphalt against anything Mother Nature throws its way.
  • Proper application: The sealcoating process takes a lot of practice and skill to get down pat. It should never be rushed, as this negatively impacts sealcoating curing in Santa Rosa, CA. Always hire a professional to sealcoat your asphalt instead of trying to do it yourself.
