What is Seal Coating and Why Does It Matter?

Seal coating applies a protective liquid layer over existing asphalt. This barrier shields the pavement from harmful UV rays, oxidation, water infiltration, oil spills, gasoline, and harsh Iowa weather. Without protection, asphalt dries out, becomes brittle, and develops cracks much faster.

Increases your asphalt’s lifespan by 3 to 5 years.

Improves curb appeal with a clean, fresh black finish.

Reduces repair costs by preventing damage progression.

Improves surface texture and decreases loose debris.
