Both rough and refined, board-formed concrete plays an important role in architecturally significant buildings and residential interiors. It can warm up stark modern interiors and provide a cool contrast to warm woods. Made by pouring wet concrete in a temporary board frame, or mold, the concrete that is revealed when the framing is removed is as varied as the types of boards used—knotty and rough, or smooth like plywood sheets. Another variable in the finished look is the size of the gaps between boards, widely spaced boards create a rough raised effect; tightly spaced boards create a smoother look.
