What does a fungus-proof coating do?

• A. Seal
• B. Waterproof
• C. Protect metal
• D. Encapsulate

Answer: (D)

A fungus-proof coating works by creating a barrier that isolates the surface from the environment, preventing fungi from contacting the material. Encapsulation achieves this by fully surrounding and enclosing the surface with the coating, forming a continuous protective layer that spores, moisture, and nutrients cannot penetrate. This complete enclosure is why encapsulation is the best answer: it describes a coating that entirely separates the substrate from the surroundings, stopping fungal growth at the source. In contrast, simply sealing may leave seams or irregularities exposed; waterproofing targets moisture passage but doesn't guarantee exclusion of spores or nutrients; a general goal to “protect metal” doesn’t specify preventing fungal growth.
