How many coats of sealer ? That’s one of the biggest questions we get asked on a regular basis . We thought we would explore the idea a little deeper and hopefully offer you some insight into what we recommend and what most manufacturers suggest.
There are many factors that come into play when deciding how many coats of sealer you should apply to your asphalt parking lot or driveway. Is it new asphalt? Has it ever been sealed before? High traffic area? So lets dig in.
If you have a new asphalt driveway we here at ClearChoice Sealing & Striping recommend that you wait 6-9 months before applying any type of sealer. This will allow the asphalt time to cure. If it is new asphalt that is properly cured a 2 coat application will give you the most bang for your buck . We also recommend a 2 coat application for any parking lot that has a high traffic load.
Why 2 coats you ask? Well if you look at your parking lot you will see that it is rough consisting of as we call it hills and valleys. So when the first coat is applied it will settle into the valleys leaving a thinner coat of sealer on the tops of the hills. These “hills” begin to wear immediately with traffic. As your tires drive across those hills and polish the sealer thus causing premature wear. Once you add the second coat you start to even out the surface and provide a “wear ” coat that will allow the sealer to wear at a more even rate. 1 coat applications usually need re-coating in 2-3 yrs and a 2 coat process can last 5 years or longer.
Most residential drives only see light traffic and once they have the first 2 coat application you can then begin to applying 1 coat of sealer every 3-5 years. I hope this has answered some of those questions. Don’t forget to check us out at www.sealcoatpaducah.com or on Facebook at ClearChoice Sealing & Striping or Instagram at Sealcoatkid.
