Purdy’s most popular brushes highly recommended for both interior and exterior painting projects and with all paints. The stiffness of the brushes makes them ideal for outdoor projects with different temperatures and humidity. A blend of Satin-Edge Nylon (Tynex) and Orel polyester are used and our special tipping and flagging process simulates the ragged ends of natural bristle, so the brush holds more paint and releases it without brush marks. Each XL brush has a unique hand-chiseled formulation for maximum paint lift and smooth “no drag” application.
