Which option correctly identifies materials used for filling sawjoints?

• A. Gypsum, premolded fillers, silicone
• B. Epoxy resin, asphalt, foam
• C. Cementitious grout, epoxy, silicone
• D. Wood shims, caulk, silicone

Answer: (A)

Saw joints must be filled with materials that provide a stable backing, allow for movement, and keep water out. The best fit uses a premolded filler to establish the correct joint shape and width, a gypsum filler as a backing to create a flush, manageable surface behind the seal, and a silicone sealant to close the joint with long‑lasting, flexible sealing. This combination ensures the joint can accommodate movement without cracking the seal, while providing a durable, weatherproof finish.

Other options don’t fit as well because they either lack the proper backing and flexible seal capacity or rely on materials that are too rigid or inappropriate for typical tilt‑up joints.
