Which materials are preferable to combat mold growth?

• A. Wood and plaster
• B. Metal and gypsum wall board
• C. Plastic and fiberglass
• D. Concrete and paint

Answer: (B)

The most suitable materials to combat mold growth are metal and gypsum wall board. Metal is inherently resistant to mold, as it does not absorb moisture, which is a primary factor in mold proliferation. Gypsum wall board, particularly when treated or wrapped with moisture-resistant coatings, can offer better protection against dampness than untreated alternatives. Using metal and gypsum in construction helps to create an environment that is less conducive to mold growth. This combination is beneficial not just for structural integrity, but also for maintaining healthier indoor air quality. In contrast, while the other materials listed may have their applications, they tend to be more susceptible to mold. For example, wood and plaster can retain moisture, making them more vulnerable, while plastic and fiberglass can harbor mold if not maintained properly. Concrete and paint can also support mold growth if the paint is not specifically treated to resist moisture. Thus, metal and gypsum wall board emerge as the strongest candidates for mold prevention in building materials.
