9 Inch Acrylic Paint Roller Covers

Paint roller covers are wide cylindrical fabric-covered tubes that are attached to a roller frame. They apply paint by rolling against a wall or ceiling in even layers. To be most effective, roller covers should be rolled in paint trays to absorb paint before being applied to the flat surface they are covering. Standard roller covers are over 4 in. long, but can be as large as 18 in. Roller covers are tubes topped with an absorbent material that slips over the paint roller frame. They are often made of synthetic fabrics (woven or knitted), such as polyester or foam, as well as natural fibers like mohair or lamb's wool. Covers come in a range of nap sizes. The thicker the nap pile, the more paint it holds.
