An asphalt surface generally lasts 25 years give or take, but your pavement life is only guaranteed if you take proper care of it. Exposure to harsh weather elements is one of the major causes of the deterioration of your surface.
Do you want your driveway to develop cracks and potholes? Imagine how it would affect your property value and curb appeal. And what if the damage done to your asphalt results in an accident or damages your car?
Seal coating protects your asphalt surface against damage done from exposure to U.V. rays from harsh sunlight and moisture from rain, snow, and ice. The moisture that seeps into the pavement affects the material’s bindings, and the freezing and thawing cycle does additional damage.
Also, seal coating protects against damage done from deicers, cleaning chemicals, and oil spills. A seal coat is painted over the surface, which forms a protective layer over the asphalt, allows the material to breathe but doesn’t let in any water or debris.
An asphalt surface typically requires a fresh seal coat every two to three years and its first coat after paving within the first 2 to 3 months. The process is easy and quick if the weather conditions are perfect. Have a look at the steps below.
Step 1: Check The Weather
Seal coating requires a constant temperature of no less than 50°F and zero moisture. The surface should not receive any rain, fog, or snow 24 hours before, and at least 48 hours after seal coating.
The environment needs to be hot and dry for proper curing and seal coating. Sunlight helps speed up the process, so if your asphalt surface is not covered, avoid cloudy days and try to maximize the sunlight by planning your work schedule around it.
Step 2: Cleaning and Stain Removal
Give your driveway a thorough cleaning. There should be no dust, debris, snow, or organic matter on the asphalt. Also, remove any oil or stains that might have seeped into the surface by treating it using the correct methods.
If you are washing your surface, make sure it has had ample time to dry before starting the process.
Step 3: Crack and Damage Repair
Do all crack filling, pothole repair, or asphalt patching before sealing the surface. If there are minuscule hairline cracks, they will automatically be filled with the seal. However, you need to do a more extensive repair because if you do them later on, your surface would need a new seal coat.
Step 4: Application and Curing
Spread the seal coating material over the asphalt surface in a thin layer and let it cure. Once the first coat has dried and the weather conditions remain unchanged, you can apply the second coat and leave that to cure. The curing of the seal coat is critical to the formation of a smooth and durable layer.
Step 5: Letting It Air
Don’t immediately open the driveway for foot or car traffic. Give your seal coat from up to a few hours to a day to air before you start using it. Immediate use would damage the layer, rendering all your efforts useless.
