While most people believe seal coating is the best way to preserve asphalt paved surfaces, others don’t. They are bent on the fact that sealants create layers of build-up that may result in cracking and water damage.
These two arguable points lead to the question: “Is seal coating necessary, and if it is, is it worth it?”
What is seal coating?
Seal coating refers to applying a thin liquid layer over a paved surface. This layer helps prevent quick wearing out by preventing direct contact with:
- Rain and snow
- UV rays
- Car fluids such as antifreeze, oil, or gas
The magic of seal coating is real. It essentially prolongs the life of asphalt paving by several years.
Note that it doesn’t cure existing issues like cracks, but it prevents such damages from happening in the first place.
Seal coating also protects against fading which means the appearance of your asphalt pavement can be maintained over the years.
Residential sealing applications include driveway seal coating and sidewalks seal coating as well as the pavements.
If you’re considering seal coating, be sure to seek consultation from an expert. They will help you decide if your paved surfaces are in good shape to take in a sealant and which sealant is most appropriate.
To avoid excessive buildup which may cause cracking and unnecessary damage, asphalt sealing should not be done frequently. For regions experiencing an extreme freeze or thaw cycles, sealing should be done at least every 2-3years.
So, is it worth it?
With the many benefits sealing offers, it is generally a recommended maintenance routine for asphalt pavement. The only drawback is cost-wise which can be a little over the top.
