3 Questions To Ask When Choosing An Asphalt Sealer

Driveway seal coating isn't anyone's favorite activity, but it's a necessary maintenance step to keep your asphalt looking good and lasting for as long as possible. Ignoring this critical task can allow water and UV rays to damage your pavement, reducing its life span and leaving it looking ragged. Waiting too long between seal coating applications can also increase the likelihood of damage that will require repairs. 

However, not all asphalt sealers are the same. The best sealing product for your specific needs will depend on your driveway, climate, maintenance plans, and more. While you should always discuss your options with your seal coating contractor, these three questions will help you narrow down your choices.

1. What Are Your Local Regulations?

Oil- and water-based sealers are two standard options for driveway seal coating. Both choices suspend asphalt and other materials in a fluid, with one using oil and the other using water. While oil-based sealers have several advantages, they can also produce adverse environmental impacts, including a strong and lingering odor from off-gassing.

Some states, cities, and counties restrict oil-based sealers, so your first step should be to check your local regulations. Coal tar is another sealer product that some areas have chosen to ban. Some retailers may also no longer sell these products, even in areas where they are still legal, so you may have difficulty finding a contractor that can use them.

2. How Often Will You Reseal?

Asphalt sealers have varying life spans, and the type you choose should depend, at least in part, on how often you plan to reseal your driveway. If you plan to reseal your driveway every few years, you can use a standard asphalt emulsion or coal tar sealer. These products degrade relatively quickly but will help beautify and protect your driveway as long as you reapply them when necessary.

Acrylic sealers are a pricier but much longer-lasting option. Although acrylic won't wear away as fast as other sealers, it may not suit all budgets. If you're planning on taking this approach, discuss the increased life span with your contractor to determine if the long-term savings from fewer resealing jobs are worth it to you.

3. What's Your Driveway's Condition?

Some sealers are better suited for filling cracks and other minor imperfections. For example, you typically need a sealer that contains sand to fill small holes and cracks adequately. You will have more options if your driveway is in relatively good condition, but you may need to choose a dedicated sealer or filler product to deal with a driveway in poor shape.

While most sealers will restore, beautify, and protect, it's crucial to remember that there are substantial differences between these products. Always discuss your options with an experienced paving contractor so you can choose a sealer that will suit your budget and requirements.
