How it's used
Used primarily as an adjective to describe objects that resist water penetration, though it can also function as a verb meaning to apply a waterproof coating. It is common to see it paired with specific ratings or levels of protection, especially for electronics or outdoor gear. Unlike some formal terms, it is the standard way to express this concept in both casual and professional settings.
Examples
This bag is waterproof, no need to worry about it getting wet.
Is the watch you bought waterproof or not?

Common mistake
Do not confuse this with 浸水, which refers to something being submerged or waterlogged. Using 防水 to describe a person who is currently underwater or soaked is incorrect.
