Do you have an asphalt driveway, parking lot, or other paved surfaces that need to be maintained? Then you need to make sure that you consistently seal

coating these surfaces. If you’re questioning whether seal coating is actually a necessary part of keeping your asphalt pavement in tip-top condition, we’ll give you a hint (YES, yes it is).

Here are 5 reasons you should consistently seal coating your driveway or parking lot:

1. Elongates Your Pavement’s Life

Seal coating provides a protective layer on top of your driveway or parking lot. It forms a shell that helps to protect it from nature’s destructive elements. Driveway sealer repels water, perhaps the single most harmful agent when it comes to deteriorating asphalt surfaces. This is especially important as we grow closer to winter months which bring cold temperatures, rain, and frost. This ultimately protects your pavement from damage, ensuring that it’ll last longer.

Seal coating also helps to protect your pavement from ultraviolet rays and other extreme weather conditions. When you seal your pavement, you have the assurance that it’ll be protected against the elements and last for many years to come.

2. Prevents High Repair Costs

As we said earlier, your unsealed parking lot or driveway will be directly exposed to the harshness of the elements, causing damage— such as cracks and potholes— in the long run. It’s more expensive to repair when the surface is damaged, and if the damage isn’t contained, you may even need an entirely new driveway or parking lot much sooner than expected.

Asphalt seal coating prevents this damage and the high repair costs that come with it, by creating a barrier to protect the asphalt from the elements.

3. Protects Against Freeze-Thaw Cycle

When a driveway or parking lot isn’t seal-coated, it’s vulnerable to the elements— especially of water damage. In the winter, this problem worsens when the water seeps into small cracks and freezes. Frozen water then expands, causing larger cracks and other kinds of damage. Seal coating assists in preventing this damage because it seals within the small cracks, helping to keep water out.

It also adds a protective layer on the surface that serves as a barrier between the asphalt and the elements. As a result, asphalt seal coating helps protect driveways and parking lots from the freeze-thaw cycle.

4. Blocks Drying Effects of the Sun

Believe it or not, the sun also has damaging effects on your driveway or parking lot— posing a threat year-round in addition to the summer months. In the same way that dermatologists recommend everyone wear sunscreen even in the winter, seal coating protects your asphalt surfaces from the sun all year long. By regularly applying a quality driveway sealer to your concrete you can prevent water, sunlight, and air from permeating your asphalt and prevent corrosion problems. 

The seal coating also acts as a shield against the ultraviolet rays of the sun, which can damage asphalt and reduce its stability, leading to cracks and other forms of damage. By protecting your asphalt with seal coating, you’re also protecting it from the drying effects of the sun.

5. Prevents Damage from Auto Fluids

Asphalt is a material made of petroleum, and when automotive fluids such as oil and gas drip onto the surface, it has the potential to dissolve into the asphalt. This chemical reaction softens the surface, eventually causing breakage and cracks. Generally speaking, you can count on oil and gas to inevitably drip onto your asphalt driveway or parking lot— this is unavoidable. While you are able to clean up the spills, it’s much easier to protect your asphalt pavement from this damage with a seal coating.

Seal coating is a liquid asphalt product that is applied on top of your asphalt surface. This product forms a protective barrier on the surface, which prevents the automotive fluids from seeping in and damaging the asphalt. In addition, seal coating also provides a protective layer against sun exposure and other weathering elements.
