A baseboard (also called skirting board, skirting, mopboard, floor molding, or base molding) is a usually wooden board covering the lowest part of an interior wall. Its purpose is to cover the joint between the wall surface and the floor. It covers the uneven edge of flooring next to the wall; protects the wall from kicks, abrasion, and furniture; and can serve as a decorative molding.
At its simplest, baseboard consists of a simple plank nailed, screwed or glued to the wall; however, particularly in older houses, it can be made up of a number of moldings for decoration.
Wooden baseboard can be available in untreated, lacquered or pre-painted versions. Pre-painted baseboards can be made from a single piece or finger jointed wood, often softwoods, while hardwoods are either lacquered, or raw.
