The Stegmeier 9CF112 Capstone Tie Wire Form with Tile Strip White is a foam cantilever form with a capstone silhouette that attaches to the tile on gunite pools. It is secured with double face tape and tie wires. Set up time is minimal, usually completed on the morning of the pour, and the forms may be removed early while the concrete is still wet enough to “slick finish” with a foam profile edging tool. Note: during installation, tie wires are positioned approximately 14″ apart and are designed to sever below the surface of the concrete.
