Under ideal conditions, typically we recommend waiting 4-12 hours, and until the first coat is fully dry and cured all the way through the film. In optimal conditions, if the driveway is sealed early in the morning and the entire driveway is in full sun and is fully dry, you may apply a second coat the same day.
It's safe to walk on right away, but it's best if you don't drive on it for at least 48 hours. There is a two- to three-day drying period for new asphalt surfaces, such as driveways or parking lots. After that, you won't have to worry about harming your new pavement while using it for walking or driving.
Upon completion, we recommend to keep vehicles off for a minimum of 48 – 72 hours. You may walk on the driveway after 24 hours.
How many coats of sealer should be applied? Low Traffic such as a typical home driveway, 1 coat is sufficient. Moderate Traffic on a parking lot, 2 coats with a third coat on the entrance and exits. Heavy Traffic 2 coats with a third coat on all travel lanes and roadways.
Even though the sealcoat is applied in what appears to be a very thin film, what happens many times in extreme heat, is that the heated pavement surface will dry the sealer so fast, that it cannot penetrate, fill the pores of the pavement, and adhere properly.
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.
It can take at least 24 hours for the driveway sealant to cure completely but if you give it 4 hours to dry it should be able to resist the rain and any possible damage that could occur.
For summer application, with full sunlight exposure (that means no shaded areas and in the high heat of the day) you should be able to WALK on the asphalt within 2-4 hours. You can typically drive on sealed asphalt after 24 hours. However, we recommend giving it 48 hours, if possible, to be sure.
Wet or dry? A hot, dry driveway above 95° F will dry to fast; the result can be a very uneven finish. We recommend cleaning the surface first using a driveway cleaner, which also serves to cool off the surface. Make sure there is no puddled water on the driveway before sealing.
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.
The best temperature range for applying sealcoat is between 55 and 90 degrees Fahrenheit. Ideal temperatures are those that start around 70 degrees Fahrenheit in the morning and increase throughout the afternoon.
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.
Sealing concrete yearly can lead to more hairline cracks, so if you have a concrete driveway, you should consider resealing it every five years. In addition, sealing an asphalt driveway too soon may trap oils within the asphalt, resulting in a driveway that is too soft or flexible.
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.
The Substrate Isn't Properly Prepared.
If the surface isn't clean and debris-free, the sealant won't stick properly and will eventually peel off.
The first coat of the first time the asphalt is sealed – a squeegee is very effective in getting sealer in all the nooks and crannies of unsealed asphalt – after that coat, sealer ought to be spray applied for maximum coverage and thickness.
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.
Wait five hours after the sealcoat is dry to the touch on a sunny day, then lower a shoe-covered foot onto the edge of the driveway. Remove your foot immediately if the sealcoat feels spongy or tacky. Step fully onto the driveway if your first foot does not affect the sealcoat.
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.
But if you want to drive on it, then you have to wait a minimum of 12 hours for it to dry and cure. If it's overcast or if rain is in the forecast, then the drying and curing process will definitely take much longer. For optimum results, we recommend that you use your driveway 48 to 72 hours after sealcoat was applied.
Once cured, a sealcoat should be applied promptly to protect asphalt from sunlight, extreme temperatures and other preliminary threats. After the initial seal, asphalt should be resealed once every three to five 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.
Sealers, particularly solvent-based sealers, will darken concrete. If unevenly applied, it will create light areas where there is less sealer, and darker areas where there's more. If applied by sprayer, it may appear like “stripes”.
