It's best to seal your driveway in the fall or the spring because the temperatures tend to be more moderate. In order to put seal coating on, the outside temperatures need to be above 50 degrees Fahrenheit. In addition, the weather needs to be free of heavy rain for 24 hours.
The best time to sealcoat your driveway is during summer when the temperature is above 50 degrees Fahrenheit. It's not advisable to seal coat in the winter as the colder season will negatively affect the performance of the sealer. The sealer may not bond with the asphalt or will not cure correctly.
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.
Rule of thumb: When it's dipping below 55 degrees F at night it's just not the right time to seal your driveway UNLESS you use our NEW Latexite Therma Seal Driveway Sealer which can be applied in temps as low as 40 degrees F.
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.
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.
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.
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 the changing leaves are still on the trees in early fall, it's ideal weather for seal coating your driveway. Plus, sealing in fall gives you the best chance of protection from harsh winter weather.
Make sure there's no forecast for rain for at least three days. You want the driveway to remain dry for at least one day before and one day after applying each layer of sealant. Opt for late spring, summer, or early fall to do this project.
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.
The Best Weather for Sealcoating is Warm and Dry
If there is any rain in the forecast for the day of the scheduled sealcoating, it should be delayed until the forecast shows no rain. The best weather for sealcoating is relatively arid conditions combined with a temperature between 50 and 85 degrees Fahrenheit.
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.
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 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.
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.
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.
Many driveway concrete sealers also waterproof concrete driveway surfaces, helping to prevent efflorescence and spalling from the sun's ultraviolet rays. Quality driveway sealing products will help keep your driveway strong, durable and looking good.
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.
Sealcoating Your Parking Lot or Driveway
Asphalt sealer takes at least seven days to fully cure. There is no need to hurry if it is not necessary. If possible, do not use your freshly coated driveway for a full 72 hours (about 3 days) just to be on the safe side.
While the advantages outweigh the negatives, there are some disadvantages that you should keep in mind before sealing your concrete driveway. Sealant can make the surface slippery. Sealants tend to dry down with a glossy or semi-glossy sheen that can be quite slick, especially when wet.
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.
