Get a Comfy Grip
Putting paint on the wall is easy, but the repetition can leave you feeling achy. Prevent the pain by changing your grip or the way you move.
Roller: Roll up at a slight angle before coming straight down.
Brush: Pinch the base of the brush with your index finger and thumb along the bottom of the ferrule.
Extension pole: Space your hands about 18 inches apart. For ceilings, roll the area in front of you, rather than directly above or behind, to avoid back strain. For walls, bow down and stretch up from the waist.
