The Smear Shield Eliminates Tape: A specially designed shield prevents paint from getting on the trim or ceiling. Your moldings and ceilings will remain perfectly paint-free. Paint an entire room or more before having to clean the paint off the edger shield. Brush-like Precision - A small brush then picks up the paint left behind by the roller and moves it precisely to the very edge of the wall. This brush provides a clean, precise cut line. You don't need to load the brush with paint. Reduces the number of painters needed for a job by 50% or more and pays for itself in labor savings from the first day on the job. Ensures that even painters with little or no experience can paint straight, even edges without paint getting on the trim. The model is designed to mount on any standard paint pole, allowing you to paint the top of the wall against the ceiling without having to constantly climb up and down a ladder. Ideal for painting above stairwells, cathedrals and vaulted ceilings, and for any user who prefers to minimize the time spent painting on a ladder.
