Marathon™ is Purdy’s most durable roller cover for maintained performance over time. Formulated with an exclusive blend of nylon and polyester fabric, Marathon™ lasts longer, paints further, and provides a smoother finish with less lint. Marathon™ is perfect for large projects as it can take wear and tear while providing consistent coverage and great final appearance. This roller cover series also has superb paint pick-up and release properties for increased productivity with less trips back and forth to the bucket. Use with either oil-base or water-base paints, and for interior or exterior applications.
