How should the edges of a reveal strip be attached to the slab?

• A. Caulked with silicon or latex caulk to produce a clean, crisp edge and thoroughly coated with bond breaker after caulking.
• B. Nailed with wood or metal fasteners
• C. Welded to the slab with epoxy
• D. Left unsealed with no treatment

Answer: (A)

The edges of a reveal strip should be sealed with caulk to produce a clean, crisp edge and to keep the joint protected from moisture and debris. After caulking, applying bond breaker on the contact surfaces ensures the strip does not bond to the concrete, allowing for independent movement and making it easier to maintain or replace the edge over time. Rigid methods like nailing or welding would create unwanted attachment and transfer stresses, while leaving the edge unsealed would result in a dull edge and exposed joint. Using caulk with a bond breaker gives a precise, durable edge that stays clean and flexible as the structure moves.
