Seal Coating – What is it, and Why is it Important?

Seal coating is a protective layer that preserves your asphalt surfaces from damage. It’s a barrier that protects it from water, oil, and ultraviolet rays.  A seal coat is a thin layer of liquid applied to the asphalt. It is made from asphalt cement or coal tar pitch, water, and additives. The additives ensure that the seal coat adheres to the asphalt.

How is Seal Coating Applied?

The all-important seal coating application is quick and easy.

• The surface is cleaned: Dirt, debris, and oil are removed to ensure proper seal coat adhesion.
• Crack and hole repair: The surface must be smooth for even seal coat application.
• Seal coat application: The seal coat is applied evenly with a brush, squeegee, or spray.
• Drying: The seal coat must dry for 24 to 48 hours. No traffic can use the surface until it dries.

Why is Seal Coating Important?

Seal Coating protects your asphalt, extends its lifespan, and improves its appearance.

Protection Against the Elements

Seal coating prevents surface damage caused by the elements. It prevents water from seeping into cracks. In colder temperatures, this water can freeze and expand causing substantial damage to the underlying structure.

Like water, the sun’s UV rays can break asphalt down over time. The seal coat shields the asphalt surface from UV rays. It also stops spilled oil and gas from softening and damaging the asphalt.

Extending Asphalt Lifespan

Seal coat protection extends the asphalt lifespan by several years preventing environmental damage and degradation. Regular seal coat saves money over time, reducing the need for repairs and delays replacement by maintaining the surface condition.

Improved Appearance

Seal coat gives asphalt a fresh black look, making driveways, parking lots and roads look better. Sealed surfaces also provide a better walking and driving experience. It is easier to keep a smooth surface clean and well-tended. Seal-coated surfaces are safer because they are well-maintained and free of potholes and cracks.

Seal Out the Elements and Make Your Asphalt Last

Seal coat protects asphalt surfaces against water, UV rays, and chemicals, ensuring it looks good for years. An investment in seal coat can save substantial amounts in repairs and early replacement so it is well worth the cost and small inconvenience of a regular seal coat application.
