Purdy’s most popular roller covers use with all paints and exterior stains, especially where a smooth, lint free finish is desired. White Dove series features a high density woven cover, made of Dralon, a derivative of nylon, which enables the paint to flow freely into and out of the cover for easy rolling and a high quality finish. White Dove covers feature thousands of miniature flagged filaments so paint leaves from thousands of tiny surfaces for a smooth, virtually perfect finish. The high density acrylic fiber is also capable of carrying large quantity of paint, leading to improved efficiency and productivity. 1-1/2 inch length outWound with a perfect spiral seam, a Purdy exclusive, for smooth rolling with no swerving or fishtailingIndustry's most lint free roller coverClean, lint-free cover is double-cleaned to eliminate any possible fiber sheddingExcellent with all paints1/4" pile height, smooth surfaces for oil and latex enamelsAll paint finishesPolypropylene core
