Sealcoating is a liquid layer applied to asphalt pavement. It blocks harmful UV rays and prevents oil, water, and gas from eating away at the pavement. Contractors often clean the surface first and then fill deep holes. The liquid sealer is spread over the asphalt by using a sprayer.
It is recommended to seal your asphalt every 2-3 years to keep it in great shape. The process should also be done on a dry day when the temperature is at least 13 degrees Celsius.
In today’s article, we’ll discuss different benefits of seal coating. Let’s get started.
It Enhances the Appearance of a Driveway
Due to constant foot traffic and other loads, the pavement gets damaged over time. This signficanlty compromises its appearance.
Sealcoating prevents cracks from forming in the first place. And if they do appear, it stops them from getting worse. Harmful UV rays will be blocked, and the cold won’t affect the asphalt. A new coat of sealcoating will also make the surface blacker and smoother. Installing it every 2-3 years will ensure that those severe blemishes never make your driveway unappealing.
It Controls the Water Damage
When the liquid layer of sealcoating is applied to asphalt, it seals the porous surface by acting like a raincoat. Since asphalt is sponge-like, the sealcoating fills the tiny holes so the water runs off. But if the water leaks through the top, it would soften the dirt beneath the asphalt. The seal will also stop this hidden erosion.
The sealcoating also stops the freeze-thaw cycle. The trapped water, when it freezes in winter, expands like ice cubes in a tray. This expansion causes small cracks to grow into big potholes. The seal stops this cycle by keeping water out.
It Stops Chemicals from Damaging Asphalt
The asphalt contains a glue-like binder made from crude oil. Chemicals like gasoline and motor oil break down this glue over time. When the glue dissolves, the rock loosens. As a result, it creates cracks on the surface.
Sealcoating fills the tiny holes in the asphalt, so chemicals sit on top rather than soaking in. Similarly, the sealants also keep the asphalt’s natural oils inside. It keeps the pavement flexible so it never cracks under pressure.
Most modern sealers are made with acrylics or coal tar, hard materials that naturally resist chemicals from cars.
It Saves You Money
The benefits we’ve mentioned above directly impact how much you’d save. For example, new pavement can cost $3,000 to $15,000 depending upon the size. By just spending a small amount on sealcoating every 2-3 years, you can delay a full repaving job for decades. It also fills the small cracks so water doesn’t get in, preventing the major potholes from forming in the first place.
You also won’t have to spend money on cleaning/washing stains, as the coating will do it on its own.
Final Thoughts
It’s important to choose a reliable, certified contractor who can properly coat your home or business without giving you any headaches. This is how you protect your investment and peace of mind.
