According to HUD lead-covered standards, what is the minimum thickness of floor covering allowed?

• A. Minimal 1/4 inch plywood
• B. Minimal 1/2 inch plywood
• C. Minimal 3/4 inch plywood
• D. Minimal 1 inch plywood

Answer: (B)

When lead-based paint may be present, the floor system needs a sturdy, stable base for the new finish so that wear doesn’t expose or spread lead-containing materials. A minimum thickness of the floor covering’s substrate helps keep the underlying lead-painted surface protected from abrasion and dust generation, making future inspections and potential abatement easier. The standard calls for at least 1/2 inch thick plywood (or an equivalent underlayment) as the base for the new floor covering. Using thinner material, like 1/4 inch, would be less durable and more prone to flex, crack, or wear, increasing the risk of disturbing lead paint. A thickness of 3/4 inch or 1 inch isn’t required by these HUD guidelines and would add unnecessary cost, though they can be used if desired for other reasons. So the practical minimum you’d use under HUD rules is 1/2 inch.
