Asphalt Sealcoating | Straight Edge Asphalt | Burien, WA

What is Sealcoating?

Sealcoating is a mixture of emulsified asphalt, water, mineral fillers, and various other mixtures. Sealcoats are applied directly to the surface of an asphalt pavement. It can be applied by rubber squeegee, broom, or mechanical spray.

Unprotected asphalt surfaces are vulnerable to the destructive effects of water, oxygen, chemicals, salts, gasoline & oil spillage. These elements weaken, destroy & soften the asphalt binder. The pavement ages, looses flexibility and will crack prematurely creating the need for patching & major repairs. Seal-coating stands between the pavement and the elements while it seals in the strength & reliance of the pavement.

Sealcoat seal’s the top of the asphalt, preventing water from penetrating the surface of the pavement and protecting the top layer of asphalt from oxidation and wear caused by exposure to the sun and air. Sealcoat also beautifies the pavement by providing a smooth, black, beautiful even surface ideal for painting lines and sweeping.

The dark charcoal black color of sealcoat improves the appearance of new & old asphalt pavements. Unprotected asphalt surfaces gradually lose their rich black color due to oxidation & weathering. In time, the pavement will begin to look rough, dull & gray. Rough spots, patches, oil spots, small cracks & surface depressions seem to disappear. The pavement looks cleaner because rainfall washes dirt & debris from the smooth, non-porous surface. Traffic lines become more visible.
