This Pack of 2 ProDec Concave Foam Roller Sleeves is specially designed for achieving an exceptionally smooth, uniform finish on fine surfaces. Each sleeve measures 4 inches (100mm) and features a concave (or dip) profile in the centre, which is engineered to release paint evenly and help prevent paint build-up at the edges. Constructed from high-density foam, these rollers are ideal for applying gloss paints, varnishes, primers, and solvent-based coatings to flat areas like furniture, doors, and cabinets. The foam material minimizes texture and air bubbles, providing a mirror-like finish.
