What is a water repellent

Answer 1

A water repellent is a substance that repels water, causing it to bead up and roll off a surface instead of soaking into it. Water repellents are commonly used on clothing, footwear, and outdoor gear to make them more resistant to water and moisture. They can be applied as a spray or coating to surfaces such as fabrics, leather, wood, and metal to provide protection against water damage and staining.
