Cirrus X roller covers feature a European polyamide yarn fabric that's soft, resilient, easy to load and holds a lot of paint. They are designed with extra capacity and durability to help tackle rough and even extra-rough surfaces-making them great for applying base coats and finish coats as well as, back rolling textured surfaces such as stucco or brick. Use these covers with all flat, eggshell and satin paints to achieve fast and complete coverage.
