Which drywall thickness is specified for HUD lead-covered walls?

• A. Minimal 3/8 inch drywall
• B. Minimal 1/2 inch drywall
• C. Minimal 1/4 inch drywall
• D. Minimal 5/8 inch drywall

Answer: (A)

When walls are being covered to encapsulate lead paint, the drywall thickness is chosen to give a durable, finish-ready surface without unnecessary bulk. The minimal thickness specified for HUD lead-covered walls is 3/8 inch because it provides a sturdy substrate that can be securely fastened, taped, and finished without adding excessive weight or cost. Thicker drywall isn’t required for this purpose and can add unnecessary weight and cost, while thinner options may not hold fasteners well or hold up to finishing without cracks. So, 3/8 inch strikes the right balance for reliably encapsulating lead paint while keeping rehab work practical.
