How can we produce a rope finish on tilt-up panels?
An effective way is to plan for the rope finish to be on the down side of the panels. Low quality, inexpensive plywood is placed on the casting slab. A retarder is then sprayed onto the plywood in the area to be textured. Parallel lengths of rope are secured to the plywood. In this operation the rope is stretched and pinned at each end and at 10-inch intervals using pins fired from a compressed air gun. After the panel has been cast and lifted, the plywood and rope are stripped away. The panels are lightly sandblasted and, if desired, color-stained. In this procedure there is no need for chipping or bushhammering the vertical rows of concrete between the rope depressions.
