ABSTRACT:
A finishing cap for concrete formwork is described herein for providing smooth finished concrete joints and corners while reducing the time, labor, expense, and expertise required to make such a joint. The finishing cap provides two non-parallel edges forming an angle, wherein the concrete formwork is fitted into the angle so provided. The angle between the edges of the finishing cap is provided so as to be somewhat smaller than the final desired angle of the finished concrete joint. A pinching action is created between the edges of the finishing cap and the formwork, and this pinching action prevents stones and concrete from entering the joint and roughing up the final finished joint. After the concrete is poured, smoothed and set, the finishing cap may be easily removed and a smooth finished corner is produced. The invention is described in relation to concrete formwork for stairs and walls.
