Why Sealcoat My Driveway or Parking Lot?

For many first-time homeowners, Sealcoating can be a bit of a mystery. What is sealcoating? Can I do this myself? How long does a Sealcoat last? Does sealcoating work? These are all very common questions, and we have the answers! Let’s take a look at these frequently asked questions and learn the importance of sealcoating your asphalt.

1. What is sealcoating? Sealcoating, or pavement sealing, is the process of applying a protective coating to asphalt-based pavements to provide a layer of protection from the elements: water, oils, and U.V. damage. There are several types of sealers to choose from out there. We only use Sealmaster products, specifically PMM Ultra Sealcoat. Our mix contains around 48-52% hard materials containing an asphalt, sand, water and polymer mix. In cases of cold weather jobs at the end of the season, we switch to a heavier Coaltar mix. 
   

2. What is the difference between Water-based and Oil-based sealers? We use the water-based sealer and will never use an oil-based product. Oil can appear more appealing at first glance due to the “wet” aesthetic and the cheaper cost, however it will leave you with a long term problem and a walking hazard. Oil-based products leave a shiny coat that is appealing at first, but at the first winter temperature, you will see it turn gray, peel away, and turn into a skating rink once frost or rain hits its surface. Our water-based mix has sand and acrylic hardeners to avoid this problem altogether.
   

3. Does sealcoating work? How long does a sealcoat last? Sealcoating not only lengthens the life of your asphalt, but it’s also a great way to gain curb appeal and give your home a quick and effective facelift. We recommend doing a residential sealcoat every 3-4 years, depending on maintenance. Sealcoating can add over 20 years to your asphalt.
   

4. Can I sealcoat my driveway myself? While there certainly are sealers for purchase from your local hardware store, we don’t recommend them. Most store-bought products are heavily mixed with latex and oftentimes are applied incorrectly, causing harm to the integrity of your driveway. By the time you factor in your labor hours, the clothes that will be stained and ruined, the cost of the product, and the frustration that can come with the job, you often end up spending more than if you let a professional help with this project. Latex-based sealers are rolled or brushed on, leaving unsightly patterns when dry. They also can be applied too thick, which, like paint, will cause the material to split open and crack, which leaves what we refer to as “surface cracks” or “check cracks”. To prevent this, we spray on our sealer, overlapping layers to ensure a smooth and even finish.
