Casting slabs should be finished

• A. The same as the floor slab.
• B. With a broom finish.
• C. Polished finish.
• D. Stamped finish.

Answer: (A)

In tilt‑up construction, the surface that contacts the casting bed becomes part of the wall as the panel is tilted into place, so the base of the wall will sit against the floor with a visible joint. Finishing the casting slab the same as the floor slab ensures a uniform texture, color, and surface quality at the floor–wall interface. This reduces visible differences after erection, improves bonding for any coatings or caulking at the joint, and minimizes the need for patching. If the bed is finished differently from the floor, a seam or texture mismatch can stand out once the wall is in place, which is why matching finishes is the best practice.
