The UV rays will attack this thin coating, and it will begin to harden and fail. If you don't take off your shoes when you come into your home, you'll track the asphalt indoors, discoloring vinyl flooring and carpets. Once the sealer starts to wear off, your driveway starts to look bad.
Is asphalt sealcoating necessary? Yes, it is a necessity as you need to protect your valuable asset. If you want your driveway to last, sealcoating is the way to go. Unprotected asphalt leads to cracks and potholes that can severely damage your foundation.
The Drawbacks of Seal Coating
One is that it can be messy and difficult to apply evenly. It's also important to note that sealants will not repair significant damage to your driveway; they will only protect it from further damage. If your driveway is damaged, you'll need to have it repaired before sealcoating it.
When sealcoating is used as part of a preventative maintenance program, it can extend the life of your driveway by up to 20 years on average.
How often do I need to reseal my asphalt driveway? We recommend that you have your asphalt driveway resealed every 2-3 years at maximum. Waiting any longer could result in faster deterioration of your pavement. And doing it too often (i.e. annually) could result in chipping and flaking.
While we still recommend those with cracks developing try to get their asphalt seal coated before it gets too cold, spring is really the best time for seal coating. It means your driveways and parking lots look great for the entire year, and warm spring weather is the perfect temperature for a well-set coat.
Sealcoating is not designed to be an asphalt crack filler, it is made for sealing the surface and protecting it from the elements such as UV light, salts and oils. It is not flexible enough to fill a crack without re-cracking and it does not have adhesion quality's that Asphalt Crack Filler has.
Yes. Every driveway should be sealed with a high-performing sealer. A sealer will protect your driveway from the following: Abrasions.
Seal coating allows for a smoother, crack-free driveway, and because smoother pavements extend pavement life by as much as 10% to 25%, you won't have to worry about replacement or repairs for a much longer period of time.
Rain and Sealcoating
Sealcoating application and drying do not pair well with rainy or even misty conditions. Rain prevents the coating from drying. Depending on how heavily the rain falls, it could also wash away the sealcoating from the surface before it has had enough time to dry.
When applied under ideal conditions, you can walk on a sealcoated pavement three hours after application. But if you want to drive on it, then you have to wait a minimum of 12 hours for it to dry and cure.
Jetcoat 10-year
10 years, however, is a long, long time and it's how long you'll have in between coats if you get Jetcoat's 10-year sealant. This long-last sealant is designed to last, with a patented formula that'll cover your driveway for 10 years.
1. APPLYING TOO MUCH SEALER OR THE WRONG KIND OF SEALER. While slathering seal coat over asphalt in a thick layer can be tempting, a “more is better” approach is detrimental to the pavement beneath. Too much sealer can lead to premature cracking, which will shorten the lifespan of your driveway.
Rain can wash away all of the hard work that you put into your driveway. The sealer will be washed away by the rain if you don't wait long enough for it to dry.
Sealcoating protects and prolongs the life expectancy of asphalt pavement by filling surface damage and providing a protective layer to keep out damaging UV rays, vehicle fluids, and water. The low cost of regular sealcoating can save you money in the long run.
Driveway sealer won't bond properly to asphalt if any dirt is present. A power washer and leaf blower are recommended for cleaning your asphalt surface effectively. If there are oil spots on your driveway, wash these areas with an asphalt degreaser the day before applying driveway seal coating.
Sand and gravel provide better traction on sidewalks and asphalt that may freeze during cold weather. Unlike deicing products, they do not melt the ice, but allow you to walk safely on the surface. The grains of sand and small stones prevent falls and a simple cleaning in the spring will be enough.
Sometimes sealcoating isn't the answer. Shallow cracks and constant patching may signal it's time to resurface your driveway. Driveway resurfacing is when you replace the top layer of asphalt with a fresh layer. Driveway resurfacing helps extend the life of your driveway for another eight to 15 years.
Sealcoating will protect against fading, and can even improve the appearance of your asphalt. It will restore the lustrous appearance of the asphalt, even if some natural fading has occurred. It will also fill all of minor surface flaws, giving the pavement a smooth and even appearance.
You'll get the best results if you take the time to repair cracks in the surface of the driveway before applying a final coat of sealant. For cracks less than 1/2 inch, use a bottle of crack filler.
Filling Cracks
As we noted above, filling in cracks costs between $1 and $3 per linear foot. However, a professional will charge a minimum service fee to diagnose and repair asphalt driveways. And so, you'll pay an average of $100 to $400 for crack repair on your whole driveway, depending on the severity.
During initial application, the asphalt should still be at least 220 to 290-degrees Fahrenheit. If the asphalt dips below approximately 185-degrees Fahrenheit before compaction is complete, its consistency stiffens up too much to finish the job properly.
Applying two coats of any sealer will dry and create a better finish much better than one thick coat. These sealers are water based, and they cure and form a film primarily during the evaporation of water from the coating. A thin coat will evaporate much faster and create a single uniform layer.
Seal coating should not be done when temperatures are below 55 degrees Fahrenheit or above 90 degrees Fahrenheit. And you should never seal your driveway in either extreme cold or extreme heat because it will cause the material that has been applied to break down quickly.
