Yea it will probably blush which looks like cloudy finish. Could possible dry away but you may need to do another coat.
How long does sealer need to dry before the rain? If it is expected that rain will fall within 24 hours after application, do not apply. Instead, for at least 12 hours, keep newly sealed asphalt dry.
It typically takes about two days for the sealer to dry, but if rain comes before that, the sealer will be washed away. It's best to wait at least 72 hours after application of the sealant before allowing any rain.
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.
One downside that might surprise you is just how scorching hot the seal coating will make your driveway during the summer months. A sealing job will give your driveway a dark color that will absorb sunlight, so definitely keep your shoes on when walking anywhere near it if the temperature is high.
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.
Asphalt driveways should be sealed once every two to three years, while concrete driveways require sealant every four to five years. Concrete often goes unsealed due to a mistaken belief that it doesn't require a sealer. Not sealing concrete can shorten the driveway's lifespan as water seeps into the concrete.
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.
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.
For silicone sealants, the curing process typically takes between 24 hours to 48 hours under optimal conditions. The difference between dry time and curing time is important to note for several reasons.
Driveway sealer will dry like paint from the top down. It may feel dry on the surface but may still be wet underneath. You can walk on the driveway as soon as it feels dry to the touch, usually just a few hours in sunny areas. Allow additional time for shady areas at all times.
This sealant dries immediately after installation. Thompson's water seal does not dry when the coat is still vulnerable and gets wet. To avoid that from happening, when you're done applying it, make sure there is no rain coming and try to avoid spilling liquids on it.
Here's a general timeline: 3-4 hours: If conditions are ideal (warm, sunny, and dry), it's usually safe to walk on a sealcoated driveway after 3-4 hours. 24-48 hours: To be extra cautious, it's best to wait 24-48 hours before driving on a newly sealed driveway to ensure the sealer has had enough time to dry and cure.
Sealants can make the surface look smoother and darker. Depending on the type of sealant you choose, it can also create more of a “wet look” with a semi-gloss or high-gloss finish. Certain types of driveway paint can even provide a fresh wash of color.
Many of these compounds are water-resistant, so the rain won't do much to help wash them away. This transfer can happen in a couple of different ways. If you maneuver sharply on your driveway or stop very suddenly, you're likely to leave a mark.
A driveway sealcoat typically must dry for at least 4-8 hours, depending on the product and conditions. Given the impact water can have on sealants, it's advisable to stay off the driveway until a contractor can rectify the issue.
Bad asphalt is characterized by visible defects such as cracks, potholes, depressions, and raveling. It may also appear uneven and have poor drainage, causing water to pool on the surface. Oxidized asphalt will look gray and brittle.
Steps for Seal Coating Your Home Driveway
One bucket of sealer will cover 760 square feet with one coat or 380 square feet with two coats. If your driveway is more porous or rough, you will need two coats for maximum protection.
Curing Time: While the sealcoat may feel dry after a few hours, it takes longer to fully cure. The curing process typically takes one to three days, depending on factors such as weather conditions and humidity levels. It's essential to allow sufficient curing time before subjecting the surface to vehicle traffic.
Five gallons of sealcoat will cover approximately 400 to 500 square feet, depending on the condition and porosity of the surface. Keep in mind that you typically want to do two coatings to ensure even coverage, especially when spraying.
It won't stretch with the crack and will simply break, doing your parking lot no good and wasting money. So, no, you should not use sealcoating to fill cracks in your lot and a reputable contractor will not apply it over cracks.
While it's recommended that the overall temperature be above 50 degrees Fahrenheit before sealcoating can begin, the best weather for this process is in the range of 75 to 90 degrees Fahrenheit.
