The ProDec 9" Long Pile Roller Sleeve is designed for painting rough and textured surfaces where a shorter pile roller may struggle to reach into the surface. Its durable woven synthetic fabric has an 18mm pile that holds and releases plenty of paint, helping cover uneven areas with fewer trips back to the tray. It's particularly useful for applying emulsion and masonry paint to semi-rough and rough surfaces. The longer pile also makes this roller a good choice for jobs involving significant colour changes, where thorough paint coverage is important.
