newish house ( less than 30 years old) has dadoo rail half way up the walls - front door opens in to hall way, up the stairs to upstairs hallway/landing. When we moved in we repainted in haste (young children, lack of time) and I painted over the dadoo rail in the same colour as the walls (think pale, magnolia type colour), now needs re doing, I have more time, and could paint the walls one colour and the dadoo rail in white. Also, is Farrow and Ball paint worth it??
