Seal Coating

Asphalt Seal Coating Protection from Seattle's Trusted Paving Company

Asphalt sealer is a water-based surface treatment used to protect an existing asphalt surface. It can be applied by hand or with a spray unit.

Asphalt sealer service is advisable 6-12 months after it has been paved. Sealcoating too soon, however, may cause damage to your new driveway. Because blacktop is naturally porous, water can seep into and through the paving. This not only causes deterioration, but also results in ridges and upheaval due to frost and freezing.


Asphalt sealer service is a quick and inexpensive way to protect your driveway and enhance the appearance of your property. Having your driveway sealed takes only a few hours and the commercial sealer used Armor Seal A-100 can provide years of protection from spills, oxidation, and the damaging weather. Additionally, asphalt sealcoating restores that rich black appearance to your driveway. This is usually the first part of your property a visitor or potential customer will see. Asphalt is also softened and broken up by gasoline, lube oil, grease, road salts and antifreeze drips from cars. Sealer protects blacktop with a coating that is impervious to these harmful elements. Unprotected driveways remain porous, dry out, become rough, and lose their life rapidly. With proper care, your new driveway will give you many years of service.

To help maintain your asphalt and protect it against the need for costly repairs, sealcoating can help improve the appearance of your asphalt driveway, parking lot, private drive or other paved surface appearance while also bolstering its level of protection from water damage, cracking or oil and gas stains.

Thinking About Applying the Sealcoating Yourself?

You could, but it is a very labor-intensive project and very messy. Seal coat is very thick and sticky and can burn if it contacts your skin. It is recommended that the initial application be done by hand. Then, if practical, every application thereafter can apply with a spray unit.


After pricing out the materials needed and considering the risk of getting seal coat everywhere, most clients feel it is well worth it to 'have it done right’. Choosing an experienced driveway sealing company is key as sealcoating at the wrong time can cause more damage than it prevents.

We recommend sealcoating your asphalt surface every 1-3 years depending on the seasonal weather. When applied properly, sealing benefits the pavement in many ways. First, it renews the dark appearance of faded asphalt, making it look, feel and wear like new. It also protects the pavement from water penetration, gas and oil spills and the ultraviolet rays of the sun, all of which can rapidly deteriorate an asphalt surface and make it less appealing and shortening the life of the product.
