Asphalt Ingredients

What chemicals are in driveway sealer?

Often, one of the first things that people see as they arrive at a building. They play a large part in the aesthetic appeal, and even larger part of the functional use, of a location. Driveway sealers contribute to overall safety — driveways with cracks or holes may pose a hazard to vehicles and pedestrians alike. To this end, many owners choose to protect their asphalt or concrete driveways with sealers. Sealers help protect driveways from forming cracks by protecting the base materials from wear due to exposure to light, temperature variations, and chemicals from automobiles. In turn, this protects the aesthetic appeal and safety of a driveway.

The question is, what is driveway sealer made of that it can accomplish this level of protection?

What is seal coat made of?

Of all the types of sealants listed above, the two most popular are coal tar and asphalt emulsion sealers. While other types of sealants may provide different benefits, these two types are the most cost-effective for larger-scale asphalt driveway projects. While there is some debate as to which is objectively better, professionals agree that these two types of sealers are very different. But what contributes to these differences? For some insight, here is a summary of driveway sealer ingredients for each type and how those ingredients affect the sealer's results.

Why driveway sealer is necessary

One of the biggest questions consumers ask when first looking into driveway sealers is why it's so heavily recommended. Longevity and economics are the answer. While not required by any means, driveway sealer is strongly recommended for a driveway as a protective and aesthetic measure. Just a few of the benefits of driveway sealer include:

  • Prevent cracks: In the United States, almost all driveways are made of concrete or asphalt, both of which are porous materials. Throughout the year, water from rain and snow seep into the asphalt or concrete, expanding and contracting with temperature changes. This constant cycle of expansion and contraction causes cracks over time, which are both aesthetically unpleasant and unsafe for cars and pedestrians. Sealants close off the pores of the driveway's base material, preventing water from getting in, therefore preventing cracks from forming.
  • Minimizes corrosion: Environmental conditions and exposure to chemicals
    associated with automobiles can cause erosion over time, eating away at the concrete, asphalt, brick, orother materials in a driveway. Combine this with frequent pedestrian and automobile traffic, and this corrosion can lead to cracks, breakage, or worn areas on the driveway. Sealants protect driveways from the elements and from chemical seepage, effectively reducing corrosion over time.
  • Keeps it clean: Dirt and oil spills are a common sight on most driveways, taking away from the appearance of a driveway. Sealants prevent oil spills from staining a
    driveway surface, making it easier to clean the surface of your driveway with a quick sweep or rinse from a hose.

The importance of driveway sealer

All of these benefits can help make a driveway look significantly better, increasing the value of the property as a whole. Driveway sealers are relatively inexpensive and can significantly reduce the need for further driveway repair over time, hence making driveway sealers are a very good investment. New coats are applied ever two or three years, starting after your initial asphalt driveway was applied that will keep your driveway in great shape.
