Trim

Trim is normally applied where walls meet floors and often underneath treads to hide the reveal where the tread and riser meet. Trimming a starting step is a special challenge as the last riser above the lower floor is rounded. Flexible, plastic trim is available for this purpose, however wooden mouldings are still used and are either cut from a single piece of rounded wood, or bent with laminations.
