PURDY PAINT ROLLER COVERS – Purdy Marathon roller covers are our most durable and productive knitted cover, made with a blend of nylon and polyester. When production matters, knit fabric holds more paint and covers more area, leaving some stipple. FOR LATEX & OIL-BASED PAINTS – For best results, use with latex and oil-based paints and primers in flat, eggshell and satin sheens. Handcrafted in the USA, this high-quality Purdy roller paint cover is ideal for drywall, concrete, masonry and decks. EXTREMELY DURABLE - Designed to hold more paint so you can paint farther per dip, this paint applicator is best for semi-smooth to semi-rough surfaces. No matter the project, there is a Purdy paint brush for exceptional results. KEEP ON ROLLING - Purdy roller covers feature durable polypropylene cores that are resistant to all paints, stains and solvents, extending their life. Ultra-durable roller cover cores eliminate bending, allowing even contact with the wall. PURDY – From the first Purdy brush built in 1925 to the wide range of painting supplies and products we make today, one thing has stayed true – our dedication to craft and quality. And it's still at the heart of every tool we make.
