What should never be sanded dry due to health risks?

  1. New drywall coatings

  2. Old drywall coatings that may contain asbestos

  3. Joint compound

  4. Painted drywall surfaces

The correct answer is: Old drywall coatings that may contain asbestos

Sanding old drywall coatings that may contain asbestos poses significant health risks. When asbestos fibers are disturbed during the sanding process, they can become airborne and be inhaled, leading to serious respiratory diseases such as asbestosis and mesothelioma. Asbestos was commonly used in building materials until the late 20th century, and the dust generated from sanding these materials is extremely hazardous. In contrast, while new drywall coatings, joint compound, and painted drywall surfaces may produce dust, they typically do not carry the same level of health risks associated with asbestos. Therefore, taking precautions when dealing with potential asbestos-containing materials is crucial, and dry sanding such surfaces is strongly discouraged to prevent exposure to harmful asbestos fibers.
