FAQ

What are Sealcoats?

Sealcoats generally consist of a mixture of emulsified asphalt, water, mineral fillers, and various other admixtures. Sealcoats are applied directly to the surface of an asphalt pavement. They can be applied by rubber squeegee, broom, or mechanical spray. Sealcoats serve to seal 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. Sealcoats also beautify the pavement by providing a smooth, black, even surface ideal for painting lines and sweeping. Sealcoats are designed for off highway use where there are low traffic speeds and tight turning radiuses such as parking lots, mobile home parks, schools, shoulders, etc. Sealcoats are different from slurry seals which use a much coarser aggregate filler and are designed for use on high speed areas with straight rolling traffic.

Why Use Seal Coat?

Sealcoating seals the asphalt pavement, preventing the oxidation and erosion of the top layer of asphalt. On older pavements sealcoating replaces fine particles lost from the asphalt surface due to oxidation. Sealcoating seals the small cracks that can turn into large cracks and prevents water from seeping down to the base material. Sealcoating helps protects the asphalt from the sun as well as the harmful effects of chemical spills such as oil and gasoline. Sealcoating provides an attractive black surface that is ideal for painting lines and other markers. Sealcoating leaves a smooth, clean surface ideal for sweeping, lowering cleaning costs. Sealcoating costs pennies a square foot compared to the dollars needed to repair or replace damaged asphalt.
