Portland sealcoating specifications are dictated by two local realities most national vendors ignore. First, climate: Wet Pacific winters with long saturation windows — paving season effectively April to October. Second, subgrade: Willamette Valley silt-loam with seasonal high groundwater — drainage is the lot-life driver. Sealcoat requires 50°F+ and 24-hour dry cure window. Typical performance in Portland: Adds 5-7 years to pavement life when applied on a 2-3 year cycle.
