Abstract
A stair tread overlay and a riser overlay made from solid wood for fitting over a conventional, exposed wooden stair having a generally rounded nose like those found in most residential general construction staircases and prefabricated staircases. The tread overlay and riser overlay cover the exterior surface of a conventional wooden stair from stringer to stringer to hide a construction grade stair tread and riser below that are made from a composite material or unsalvageable hardwood to present an attractive, solid wood surface that is finishable.
