Summertime is the ideal time for adding your driveway sealer yet doing this isn’t always possible. There can be times you need asphalt sealer; now, and doing so, you are constantly monitoring the weather.
The dry time of asphalt sealer varies depending on the weather. This is why applying asphalt sealer in the summer is ideal. Asphalt sealer dries quickly but applying it in the summer allows it to cure correctly with natural warmth and sunlight: summer’s heat, low humidity, and strong sun speed up drying.
If you get a substantial amount of rain on driveway sealer, it can ruin all your efforts. While alight rain or a splash from lawn sprinklers can mark the surface, you’ll find rain-washed sealer leaves an uneven or non-existent coat. (Learn How To Turn On Sprinkler System)
In our guide, you can learn more about applying your driveway sealer hours before any rain to avoid issues.
By the end, you’ll know how and when to seal a driveway yearly to avoid unsightly hairline cracks or other issues that can appear on your concrete driveways.
How Long Should I Let My Driveway After It Is Sealed?
After a good job of sealing your driveway, worrying if it’s going to rain doesn’t do you much good.
Drying times of asphalt sealers will vary between brands, although all of them can mark if you step on the seal coat unless you are sure the best blacktop sealer is 100% dry.
The usual drying times are from 4 to 8 hours in the best sealing weather, which is warm and can help speed up the curing time.
On average, a driveway sealer will require at least 6 hours of drying time on the asphalt surface after you apply driveway sealer and rain arrives. You can, however, find a quick-dry sealer that curates in about an hour, yet most often, these are sold in bulk to commercial enterprises rather than to seal driveway at home.
You may think the coating is dry following the usual drying times, yet you need an average of 7 hours before walking across your driveway, and it takes 24 hours before you can drive onto your driveway. (Find the Best Waterproof Sealant Paint)
You may ask, as many do, what happens with rain 12 hours after sealing driveway? It is here that your environment makes a significant difference.
If the temperature is over 50°F (10°C), 12 hours of drying time is sufficient to make the driveway sealant waterproof. The sealant may take up to 24 hours to fully cure, but 12 hours is usually sufficient.
If rain falls after that time period, you may notice a minor loss of gloss in some areas of your driveway. This indicates that some of your sealers were washed away by the water.
If your driveway appears “patchy,” it signifies that some sealers were washed away by rain. As a result, when the weather is nice, reseal that area, or perhaps the entire driveway. Don’t be alarmed if your sealer is shining all over. Your driveway is entirely secure!
If you apply your driveway sealer, rain forecast delivers mild rain after 12 hours; you should be safe unless there are wide areas of missing or weakened sealer.
When Can Driveway Sealer Get Wet?
What many homeowners often overlook when using a paving sealer, driveway use isn’t one of them; it is the application of a second coat. A good explanation, yes, rain can wash your sealer away, so fresh asphalt needs the first coat applied early enough for you to apply the second, or you could seal wet concrete and ruin the job.
- They apply most driveway sealers in two coats.
- Let your first coat of sealer dry for at least 8 hours before applying the second coat.
- Wait 24–48 hours after the second coat before driving on sealer on your asphalt driveway for the complete curing process.
The driveway sealant will be impervious to rain in the vast majority of cases 12 hours after application. After 12 hours, the sealer will have enough to withstand rain if you apply it in good conditions.
Wet surfaces can create streaks, as well as extend drying times, and yes, rain can wash your fresh seal coat off the side of your driveway.
When sealing the driveway, you are safe; rain will then runoff once the surface turns a flat black color. Once the surface turns a flat black color, rain will not affect concrete driveways. If light rain hits close to the final curing time, you may get away with it if you first seal your driveway in sunny clear skies and the air temperature is warm enough to evaporate the rain from the freshly sealed driveway.

Here are the various sealers you can find and the drying times associated with them. You can get additives that can allow us to speed up the curing of wet concrete, yet the times here are without them.
Penetrating Concrete Sealer
On the market are penetrating concrete sealers such as siloxanes, siliconates, and silanes, which penetrate concrete driveways to produce a moisture-proof barrier. The surface of a penetrating concrete sealer may cure in approximately 30 minutes, but the sealer works for another 72 hours beneath the surface.
Silicate concrete sealers dry in 30 minutes, but they work underneath for 90 days. Because this is a solvent-based sealer, it dries faster than water-based sealers.
Acrylic Concrete Sealer
Speaking of water-based sealers, these are great for interiors and exteriors. The drying process takes between four and 12 hours on the surface. You can walk on them after a few hours, but they take 48 hours to harden.
Stamped Concrete Sealer
Stamped concrete sealant flourishes in specific weather conditions, and it can’t be applied until the concrete has completely dried and cured. It takes 3-5 days for stamped concrete to cure completely. If anyone says don’t get it wet, you’ll find a correct explanation; yes, rain in the first 36 hours can ruin the seal coat of your driveway sealer.
What Happens If It Rains After Sealing Concrete?
As the sealer dries, it can become cloudy, which is undesirable instead of a shiny appearance. If it rains, yes, rain can wash the sealer away, and it is only safe after 24 hours. You can, however, use additives that can allow us to speed up the curing process.
Preparing the driveway for sealing can take a full day, although your driveway sealing project for your driveway sealer application phase may only a few hours per coat for a standard driveway.
Most driveway sealer manufacturers recommend two applications with an eight-hour drying time between coats, so this project will take all weekend, even if you use additives that can allow us to speed up the curing times. You’ll find the best sealing weather starts in the morning hours, and the driveway surface temperature is getting warmer. Seal your driveway now, and you should get the first coat done and dried so rain will not affect the new asphalt and blacktop sealer coating.
Here is a quick project step-by-step guide to carrying out asphalt installation projects.
Step 1: Cleaning and Priming
Use the soap nozzle on your power washer or garden hose applicator to apply the driveway cleaner. You need to get rid of loose dirt and oil spills before applying sealer.
Step 2: Rinse with a Strong Stream
Wash away soap and grime residue with a 40-degree power washer nozzle. Rewash the driveway with clear water and let your driveway completely dry before sealing.
Step 3: Pretreat Oil Stains
Pour treatment on any oil stains and brush into the pores. Let the primer dry fully before applying the driveway sealer.
Step 4: Asphalt Repair and Crack Filling
Step 5: Stir
Start at the top of the pail and slowly descend the mixing paddle into the contents at the bottom. To blend the water and particles into a smooth consistency, rotate the mixing paddle up and down.
Step 6: Cut in the Edges
Dip your brush into the sealer and apply a liberal coating to all four edges of the driveway.
Step 7: Stage the Pails
Estimate the coverage of each pail and place each pail along the driveway. Driveway sealer can splash onto your garage door and sidewalk as you pour it and is often impossible to remove.
Step 8: Pour onto the Driveway
Begin at the driveway’s top left or right edge and pour the sealer in an upside-down U-shape.
Step 9: Spread the Sealer
Begin at one leg of the upside-down ‘U’ and distribute the puddle across the driveway and down the opposite leg evenly. Let it dry overnight.
Apply sealer again the next day. Wait 48 hours before driving on the sealer.
What is the best weather and temperature?
The greatest time to seal an asphalt driveway is in the morning hours, when the temperature is between 75 and 90 degrees Fahrenheit, with sunny clear skies and hours before any rain. When the driveway surface temperature and air temperature are both at least 65° F and rising, sealers can still be applied.
During the curing process, the temperature should not fall below 60° F inside the minimum drying time after you seal a driveway.
