Just like Minnesotans have to get used to the temperature fluctuations throughout the year, the asphalt has to adjust too. Rain, UV rays, chemicals, and temperature will all negatively impact pavement over time—especially due to the extreme freeze/thaw effect of the North. A natural cause, seasonal change results in damage as the asphalt expands and contracts, which eventually causes cracks or potholes; then, when water gets in, it starts to deteriorate even more. To help pavement last longer, it’s always beneficial to finish the job with a sealcoat.
While it’s a great way to protect your investment, a sealcoat also helps improve a home or business’ curb appeal. When a paving job has been finished with a sealcoating, it adds a shiny and attractive coat of protection. That slight shine helps reflect some of the UV rays so that it doesn’t have quite as damaging an effect as it would on untreated asphalt. Plus, it adds a beautification element to the pavement that helps it look smooth and well-maintained.
All-in-all, sealcoating is a great way to invest in your long-term paving budget and property maintenance.
To keep up with the elements, a pavement’s sealcoat should be redone every 2-3 years. It works best in the fall since the temperatures are more moderate and there’s not as many sudden fluctuations to worry about. It’s a cost-effective preventative maintenance that we always recommend.
