What is the minimum drywall thickness specified for HUD lead-covered walls?

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

Answer: (C)

Covering lead-painted walls with a protective barrier hinges on using a practical and durable drywall thickness. The minimum specified for HUD lead-covered walls is 3/8 inch. This thickness provides a solid surface that can be properly fastened, taped, and finished with joint compound to create a sealed barrier against lead dust and debris. It’s thick enough to resist punctures and cracking during normal use, yet not so thick as to add unnecessary weight or cost. Smaller thicknesses would be more prone to damage and joints could fail, compromising the barrier. Thicker drywall isn’t required for this purpose and would add extra cost and weight without adding essential benefit for encapsulating lead hazards.
