we buy a pair of the 8 lb weight . in we workout room , we set the weight on a ledge that be paint . we have two other set of neoprene weight that we buy from target a couple year back and have no problem do this . these weight stick to the paint and pull it right off the ledge . so we put a mat under they . next ... they stick to the wall when they get too close . luckily we have more paint to touch everything up .
