Paint Roller Cover 18" L 1/2" Nap Knit-Fabric Super/Fab Yellow, Wooster R240-18 Achieve smooth, even coverage on large surfaces with the Wooster R240-18 Super/Fab 18-inch Paint Roller Cover ? a high-capacity knit fabric roller designed for professional-grade results on interior and exterior projects. Featuring a 1/2-inch (0.5625") nap, this golden yellow cover is ideal for use with flat and satin paints, stains, and waterproofing coatings, delivering consistent texture and excellent release without streaks or patchiness. The roller?s proprietary golden yellow knit fabric is engineered for maximum paint capacity and controlled release, reducing the need for frequent reloading and minimizing roller marks. It resists matting during use, maintaining its structure and performance even under extended rolling sessions. While not shed-resistant, it provides a smooth finish when used with proper technique and quality paint. Built with a green double-thick polypropylene core, this roller cover resists water, solvents, and cracking?ensuring dimensional stability and durability through multiple uses and cleanups. The large core fits securely on standard 18-inch roller frames, including Wooster BR036-18, BR045-18, BR047-18, and works seamlessly with the BR412-21 paint tray for efficient workflow. Made from microfiber and knit fabric, the cover is suitable for both water-based and oil-based coatings, making it a versatile choice for walls, ceilings, concrete block, stucco, and other semi-rough surfaces. Its 18-inch length speeds up coverage on wide areas such as garages, barns, fences, and commercial walls. Weighing just 0.340 lb and packaged in a protective bag, this single roller cover is easy to store and transport. Two endcaps are included to protect the roller during storage and prevent paint from drying on the core ends.
