A paint roller is a paint application tool used for painting large flat surfaces rapidly and efficiently. The paint roller typically consists of two parts: a roller frame and a roller cover. The roller cover snaps onto the frame and absorbs the paint and transfers it to the painted surface. Accessories with paint rollers include end caps (to hold the roller cover in place) and splatter guards. Paint roller poles attach to frames and allow users to reach areas otherwise unreachable and reduce the amount of ladder work needed on a job. Power rollers are electrically powered paint applicators that are designed to continually send paint to the roller cover helping to avoid bending and stretching to re-apply paint to a roller. Many of these products are sold in sets and combination kits.
