Hi, I want to paint the floorboards in our bedroom and need to know if I need to sand them first, or if I can just wash and paint onto the floorboards without sanding? Should I also prime them first? Does anyone have any recommendations for paint - am thinking of using a Farrow and Ball floor paint, but not sure what colour, an off white or maybe pale grey? Just so you know our style, the house is an old Victorian and we have lots of Farrow and Ball already. Am loving the look on the farrow and ball home page here Thanks
