Reveal strip edges should be attached to the slab using what method?

• A. Caulked with silicon or latex caulk to produce a clean, crisp edge and bond breaker after caulking.
• B. Nailed with wood staples
• C. Welded to slab with metal
• D. Pinned with epoxy only

Answer: (A)

In tilt-up detailing, the reveal strip is meant to create a sharp, clean edge and to keep the wall panel and slab from bonding rigidly together. Attaching the reveal strip with caulk—the sealant being silicone or latex—provides the needed combination of grip and flexibility. The caulk secures the strip to the slab while remaining flexible enough to accommodate movement from temperature changes and concrete shrinkage. That flexibility prevents cracks and spalling at the edge and yields a crisp, uniform reveal after finishing.

Using rigid methods like nails, welding, or epoxy pins would create a fixed connection that can transfer movement and stress, risking cracks or delamination at the edge and a less precise finish. The caulked approach intentionally introduces a bond breaker at the interface, so the reveal stays visually clean while the slab and wall can move independently.
