Asphalt driveways are beautiful and will last long when properly maintained. However, asphalt surfaces are prone to damage caused by exposure to snow, rain, UV rays, oxidation (the greying and loss of its deep black color), and constant pressure from vehicles driving over it. This begs the question of whether or not it is a good idea to sealcoat your asphalt driveway, and when would be the best time to do so.
Here are some common indicators that you need to seal your driveway:
Just like our skin, asphalt tends to age due to constant exposure to natural elements, and has a tendency to crack and flake when it gets to too dried out. It becomes brittle and weak, and will eventually break if not seal coated on time. Grass, roots, and water runoff (from sprinklers and hoses) are also culprits in speeding up the decay of your driveways. Sealcoating your asphalt driveway will not only help extend its lifespan, it will also prevent further damage.
Before actually applying sealcoat, you will need to clean the asphalt surface thoroughly. Here are some steps to guide you on how to prep your asphalt driveway before sealcoating.
Freshly laid asphalt should not be sealed right away. Ideally, an asphalt surface needs to be cured (allowed to dry and set) for at least 6 months before sealing. The ideal interval per sealing would be 2-3 years.
Sealcoating should be scheduled during fair weather months – without any forecasted rain for at least 48 hours. Temperature should be at least 15°C or higher, but not more than 32°C. If the asphalt is too hot, the sealant will most likely melt and not cling properly to the surface of your driveway. This can result in an uneven finish.
Most sealers on the market need approximately 24-48 hours to cure before you can use your driveway again. However, Action Seal’s sealers only need 3-4 hours to dry if applied during ideal weather conditions. This means, you get to use your driveway sooner!
On a long-term basis, sealcoating is beneficial not only to your property but to your pocket as well.
To answer the question of whether or not to seal your asphalt driveway: the benefits far outweigh the disadvantages, if there are any at all.
So, if a friend or colleague asks you the same question… tell them, yes, sealcoating your driveway is the best decision you can make to improve the appearance and prolong the life span of your driveway.
