In some cases, a residential driveway will only need one coat of sealant. However, if the asphalt sealcoating has never been sealed before, it may take a second coat to give it the rich, deep finish that most homeowners prefer. A second coat may also be indicated if there is some “unraveling” of the asphalt.
Ideally, you should sealcoat once every 2 or 3 years. Make it once every 2 years if your driveway gets a lot of traffic and is constantly exposed to chemicals, snow or oils. Video: How often to seal a driveway? You need to also seal your driveway after every repair.
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.
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.
Sealcoating not only extends the life of your asphalt pavement, but it's also an effective way to save money. Unprotected asphalt leads to cracks and potholes which will cost you more in repairs.
The Drawbacks of Seal Coating
There are some drawbacks to sealcoating, however. 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.
He added that sealing a driveway could yield unwanted consequences: Oil from the bitumen (the black glue that holds the asphalt together) will be tracked into the home, or the sealant could wear away unevenly, making the surface look as if it's peeling.
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.
Industry standards recommend that you wait one year or go through one winter before you seal coat a new driveway. How often should I seal coat my driveway? Industry standards recommend every two years; allowing the sealer to wear away before you reseal the driveway.
Yes. Every driveway should be sealed with a high-performing sealer. A sealer will protect your driveway from the following: Abrasions.
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.
Driveway sealing can protect your investment. The bottom line is that sealcoating and proper maintenance for your driveway can prevent small cracks from turning into big ones and keep water from seeping into the base material.
Rain and Sealcoating
Sealcoat material will not properly adhere to the asphalt pavement if it is wet. Asphalt must be 100% dry in order to apply the material. Sealcoating application and drying do not pair well with rainy or even misty conditions. Rain prevents the coating from drying.
You can apply sealer at any time of day as long as the pavement temperature does not fall past 40 degrees at night. You can even apply the sealcoat during the nighttime. Many people choose to start their sealcoat project around 10 AM as the sun's temperatures begin to rise, and the humidity is not too oppressive.
There Are Cracks or Holes in the Surface
Another sign that your driveway needs to be sealed is cracks or holes in the surface. These can be caused by several things, such as tree roots, weather damage, or normal wear and tear. If you notice any cracks or holes, it's important to have them repaired as soon as possible.
Extends pavement life.
The combined impact of all these things that sealcoating does to a pavement is that it extends pavement life. A well-constructed asphalt pavement can last well beyond 15 years when properly maintained. And sealcoating is an essential part of that maintenance process.
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.
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.
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.
How long do I have to stay off the driveway after it is completed? Upon completion, we recommend to keep vehicles off for a minimum of 48 – 72 hours. You may walk on the driveway after 24 hours.
Although latex acrylic sealers are one of the most expensive options, they're one of the best asphalt driveway sealer options because they're durable, stain resistant, and non-toxic. They can last 5 to 10 years and are UV-resistant to stand up against hotter climates.
The tar-like substance is actually an emulsion of water and liquid asphalt which penetrates and seals small cracks in the existing pavement. The “gravel” is actually aggregate that sticks to the emulsion and, after rolling and sweeping, provides a skid-resistant surface to improve safety.
