How To Make Your Asphalt Seal Coat Last Longer

Posted on

Seal coating is an important step in asphalt maintenance. It's what seals the pavement and prevents water, salt, and other elements from causing damage to the asphalt surface.

A well-done seal coat job can last for a few — but if you want it to last even longer, there are a few extra steps you can take. Read on to learn more.

Regular Maintenance

The most important thing you can do is regularly maintain your asphalt surface. This includes regularly sweeping or vacuuming debris such as leaves, dirt, and sand. The coating also needs to be free of any dirt or other contaminants that can reduce its effectiveness.

You should also inspect the area for any cracks or holes that need to be filled in with patching compounds or other asphalt repair materials. Smaller cracks usually begin to deteriorate over time and can allow moisture to get in, which can lead to further damage.

Additionally, make sure to clean any oil spots immediately with a degreaser or detergent solution made specifically for asphalt surfaces. All these steps will help protect your seal coat and ensure it lasts longer.


Sealants are a great way to protect your seal coat from wear and tear caused by weather exposure, ultraviolet rays, and vehicle traffic. They create a barrier against water and other elements that can damage the asphalt.

Re-sealing should be done every few years, depending on the pavement conditions and how frequently it is used. This can help to extend the life of your seal coat and keep it looking great without needing to be replaced.

Various types of sealants are available on the market today, ranging from acrylics and epoxies to polyurethanes and silicones — all of which have different levels of durability and longevity when it comes to protecting your seal coat.

For example, a polyurethane sealant is more resilient to water infiltration and chemical exposure than an epoxy-based sealant, but it is also more vulnerable to wear and tear. You can choose the right one for your project's goals depending on your budget needs.

Expertise Matters

It's always best practice to consult a professional before beginning any major project like this one. They can give you advice on what type of material is best suited for your particular project. They can also guide you on proper installation techniques so that everything is done correctly the first time around. This ensures that your new asphalt seal coat will last for years with minimal effort required from you.

In some cases, an expert may even be able to recommend a sealant specifically designed for your type of pavement. This would further ensure the longevity and effectiveness of the seal coat. For more information on asphalt sealcoating services, contact a professional near you.
