What is Sealcoat?
Sealcoat is a thin layer of liquid asphalt
Covered by a thin layer of aggregate
That is rolled and pressed in place
With loose surface aggregate swept up after 24 - 48 hours
and cures into a tight, dark surface
Why Seal Coat ?
All Asphalt Oxidizes and Deteriorates
With time, weather and changes in temperature
Asphalt dries and cracks
Pavement rapidly degrades after cracking starts, and then water
infiltrates
If left untreated, all asphalt streets eventually pothole
Early treatment is cost effective
$1 for preventative treatment here
Prevents spending $10 - $15 to fix this
