When To Seal New Asphalt Driveway

Seal coating your asphalt driveway is important to maintaining its appearance and longevity. Asphalt is a mixture of sand, bitumen, and stone, making it fairly porous. Once your new asphalt driveway has cured (usually 30-90 days after asphalt installation), it should be sealed. Seal coating helps and protects the driveway from the elements and keeps it looking great for years.

Sealing a new asphalt driveway within the first year is generally recommended. It will help to protect the surface from weather damage and wear and tear. If you are in a location with extreme winters, it is especially important to seal your driveway before the cold weather hits.


Benefits of Sealcoating Asphalt Surface

Sealcoating your asphalt driveway has many benefits, including:


Sun’s UV rays Protection

Asphalt is made up of petroleum products, and UV light can cause these materials to break down and become brittle. Seal coating helps protect your asphalt driveway from the sun’s ultraviolet rays, which can cause fading and discoloration.


Protection Against Water Damage

Seal coating creates a barrier against water, which can penetrate the asphalt and cause cracks and potholes. Water may accumulate on the surface of the pavement due to improper drainage. Asphalt is porous; water can seep into the material and cause it to expand, crack, and crumble. If water cannot drain away from the asphalt, it will sit on the surface and eventually cause damage.


Prevention of Harmful Chemical Stains

Oil and gas spills can damage the asphalt driveway and the environment. The oil and gas can penetrate the asphalt and cause cracks and potholes, leading to more permanent damage. If you have an oil or gas spill on your driveway, you should immediately contact a professional to clean it up. Seal coating will also help to prevent oil and other stains from penetrating the asphalt and causing permanent damage. 


Creates a More Inviting Curb Appeal

Seal coating also enhances the curb appeal of an asphalt driveway for residential and commercial properties by giving it a fresh, new look.


Increased Life of Your Driveway

Seal coating can prolong the lifespan of your asphalt driveway by protecting it from the elements. The coating helps to protect the driveway from the sun’s UV rays, water damage, stains, and other wear and tear.


Best Time to Seal a New Driveway

Most experts recommend waiting 30-90 days after installation before seal coating a fresh asphalt driveway. It allows the driveway to cure and harden fully, so the sealer can properly adhere. If you seal too soon, the sealer may not bond correctly and could peel or chip away.


How to Seal an Asphalt Driveway

Seal coating is a fairly simple process that homeowners or professionals can do. First, any cracks or potholes should be repaired, and then the entire surface should be cleaned with a power washer or other cleaner specifically formulated for asphalt driveways. Once the driveway is dry, the sealer can be applied with a brush, roller, or sprayer.

Two coats are usually recommended, and the second coat should be applied perpendicular to the first.


When Should You Do It Yourself, and When Should You Hire a Professional

You can seal your driveway if you feel confident in your ability. Sealing is easy, but it is important to do it correctly.

First, you have to clean the surface of your driveway thoroughly. Then you will need to apply a primer, followed by two coats of sealant. The best time to do this is in the late spring or early summer when the weather is warm and dry. 

Seal coating an asphalt driveway is a fairly straightforward process that many homeowners can do. But let us remind you that it can cause more damage and expenses if not done properly. It’s better to leave the seal coating to professional paving contractors. DIY kits are available for around $100, but hiring a professional for this job is generally best.

However, if you’re unsure of your ability to do a good job or don’t have the time, you may want to hire a professional. 


Expert Recommendation and Conclusion

In conclusion, sealing an asphalt driveway is a sound investment. Sealing an asphalt driveway is important to protect the surface from weather damage and wear and tear. Generally, it’s advised to seal a fresh asphalt driveway within the first year.

Most experts recommend regular maintenance, sealing an old asphalt driveway every two to three years. However, some driveways may need to be sealed more frequently if they are subject to a lot of wear and tear.
