Asphalt sealcoating is a crucial maintenance service that protects and extends the life of your asphalt driveway, parking lot, or roadway. If you’ve noticed your asphalt starting to look dull, cracked, or worn out, sealcoating might be just what you need to restore its appearance and durability. But what exactly is asphalt sealcoating, and why is it so important? We at Andersen Asphalt & Striping would like to break it down.
What is Asphalt Sealcoating?
Asphalt sealcoating is the process of applying a protective liquid coating over the surface of asphalt pavement. This coating is typically made from a mixture of refined coal tar or asphalt emulsions combined with additives like sand and polymers to improve durability and flexibility. Once applied, it forms a black, protective layer that seals the asphalt surface from external damage. This layer acts as a barrier, shielding the pavement from the harmful effects of sunlight, water, oils, chemicals, and other contaminants. Sealcoating also helps fill small cracks and imperfections on the surface, preventing them from becoming larger problems.
Why is Asphalt Sealcoating Important?
1) Protects Against UV Damage. Asphalt is made from bitumen, a petroleum product that naturally deteriorates when exposed to the sun’s ultraviolet (UV) rays. Over time, this UV exposure causes the asphalt to dry out, lose flexibility, and crack. Sealcoating blocks UV rays, preserving the asphalt’s natural oils and keeping it strong and pliable.
2) Prevents Water Penetration. Water is one of the biggest enemies of asphalt. When water seeps into cracks, it can cause the base layers to weaken, leading to potholes and major structural damage. Sealcoating acts as a waterproof barrier, preventing water from penetrating and damaging the pavement beneath.
3) Resists Oil & Chemical Spills. Vehicles often leak oil, gasoline, and other chemicals that can break down asphalt and accelerate its deterioration. Sealcoating protects your pavement from these harsh substances, reducing the risk of damage and costly repairs.
4) Improves Appearance. Over time, asphalt surfaces fade and look worn out due to sun exposure and daily wear. Sealcoating restores the deep black color, giving your driveway or parking lot a fresh, new look. This not only boosts curb appeal but can also increase property value.
5) Extends Pavement Life. Regular sealcoating significantly extends the lifespan of asphalt pavement. By protecting the surface and preventing damage, it reduces the need for frequent repairs or premature replacement. This means saving money in the long run.
6) Cost-Effective Maintenance. Sealcoating is an affordable way to maintain your asphalt. The cost of sealcoating is minimal compared to the expense of repairing or replacing damaged asphalt. Investing in sealcoating every few years is a smart way to keep your pavement in top shape.
When Should You Sealcoat Asphalt?
Most experts recommend sealcoating every 2 to 3 years, depending on the amount of traffic, weather conditions, and the current state of the pavement. Applying sealcoat too early or too late can reduce its effectiveness, so proper timing is key.
