The finger joint can also be valuable when creating baseboards, moulding or trim, and can be used in such things as floor boards, and door construction.
Prepainted baseboards can be made from a single piece or finger jointed wood, often softwoods, while hardwoods are either lacquered, or raw for staining and made from a single piece of wood. MDF (medium-density fiberboard) is a common material used for baseboard trim and molding .

Lap joints can be used to join wood, plastic, or metal. A lap joint can be used in woodworking for joining wood together. A lap joint may be a full lap or half lap.
