Designed specifically for interior painting projects, the smart painter system allows you to finish up faster, safer and easier. The spatter shield prevents messy paint spatters and the medium nap roller cover provides a smooth even finish. Roller cover is compatible with water or oil-based paints. The Twist-lok® extension pole allows you to reach up to paint walls and ceilings or down to paint walls or floors, without bending! Spatter shield with single-handed operation allows you to quickly rotate shield to correct angle as you paint. Translucent shield allows you to see your roller cover and makes loading paint and painting much easier. Detachable roller frame can be used with the 2 to 4 ft extension pole or by hand. Twist-lok extension pole can also be used with other standard threaded tools such as edgers, corner painters and more.
