Don’t Let Your Asphalt Investment Crumble: Why Sealcoating is Your Pavement’s Best Defense
Your asphalt pavement represents a significant investment in your property, whether it’s a residential driveway or commercial parking lot. Yet many property owners overlook one of the most cost-effective ways to protect this investment: sealcoating. Understanding when and why your pavement needs this protective treatment can save you thousands of dollars in premature repairs and extend your pavement’s lifespan dramatically.
What is Asphalt 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. Think of it as sunscreen for your pavement. Sealcoating is the application of a protective layer to asphalt surfaces to keep out water, chemicals, and other harmful things that damage the surface over time and shorten its lifespan.
Asphalt pavement, to keep in simple terms, is primarily rock and/or stone and gravel, along with a binder. The rock, or aggregate, is held together with this binder also known as asphalt cement. Maintaining this binder is essential in prolonging the deterioration of asphalt surfaces.
Why Your Pavement Needs Sealcoating Protection
UV Ray Protection
Asphalt pavement reacts poorly to UV rays. When constantly exposed, its binder — the glue that holds the sand and stone in place — quickly deteriorates. The sun’s rays cause a natural process called oxidization, which can dry out the bitumen in your asphalt pavement, making it brittle and prone to cracks and damage. By applying sealcoating, you can effectively slow down oxidization and keep your asphalt looking new and resilient.
Water Damage Prevention
Cracks in your asphalt provide an entryway for water, which can result in further damage, especially during freezing temperatures when the water expands. Sealcoating fills in these cracks and forms a protective barrier, preventing water from entering and causing additional harm to your parking lot. This is particularly important in regions like Pennsylvania, where 30-50 freeze-thaw cycles each winter can wreak havoc on unprotected pavement.
Chemical Resistance
Asphalt and gasoline share similar chemical properties, making fuel spillages a potential hazard for your asphalt pavement. Sealcoating creates a protective layer that prevents gasoline from binding with the asphalt surface, shielding your parking lot from softened and weakened areas caused by fuel spills.
When Should You Apply Sealcoating?
Asphalt driveways benefit from sealcoating six months to a year after the asphalt is applied. New asphalt surfaces should not be sealed any earlier than six months. Sealcoating offers protection for up to three years if your driveway is in good condition and free from large cracks or other damage.
By sealcoating every two or three years your asphalt is protected. However, timing is crucial for proper application. Temperatures must be a minimum of 50 degrees and rising for a period of not less than 24 hours. Do not apply when temperatures are forecasted to get below the 50 degree mark.
The Financial Benefits of Sealcoating
A regularly scheduled sealcoating program will more than double the life of the asphalt, saving you significant dollars down the line. Instead of having to pay thousands of dollars for new pavement, it is more cost effective to spend only pennies on the dollar per square foot to maintain.
Sealcoating extends the lifespan of your asphalt pavement, ultimately saving you time and money. By investing in regular sealcoating every few years, you can avoid expensive repairs and enjoy a durable, attractive parking lot for many decades to come.
What Sealcoating Cannot Do
It’s important to understand that sealing isn’t the solution for cracks or potholes. It’s not meant for repair but for prevention. What sealcoating doesn’t do is fix pavement defects or even restore the flexibility to your pavement. Sealcoating works best on surfaces that are still in good condition. It is a maintenance step rather than a general repair.
Professional Application Matters
While DIY sealcoating products exist, professional application ensures optimal protection and appearance. Prior to application the surface must be completely clean and dry using sweeping methods and/or blowers. If the surface is not clean and dry, then poor adhesion will result. Professional contractors have the equipment and expertise to properly prepare surfaces and apply sealcoating evenly.

Conclusion
Sealcoating is one of the most cost-effective investments you can make in your asphalt pavement. Sealcoating protects and prolongs the life expectancy of asphalt pavement by filling surface damage and providing a protective layer to keep out damaging UV rays, vehicle fluids, and water. By understanding when and why to apply this protective treatment, you can maximize your pavement investment and avoid costly premature replacement.
Don’t wait until damage becomes extensive. Once you have visible damage on your asphalt surface, it’s often too late to sealcoat. Schedule regular sealcoating maintenance every 2-3 years to keep your pavement looking great and performing reliably for decades to come.
