Waterproof sprays are protective coatings designed to repel water from various surfaces, such as fabric, leather, and shoes. These sprays create a barrier that prevents moisture from penetrating the material, helping to keep items dry and prolong their lifespan. They are commonly used for outdoor gear, clothing, and footwear. Most waterproof sprays contain silicone or fluoropolymer compounds that enhance water resistance. To use them effectively, surfaces should be clean and dry before application. After spraying, it's essential to allow the product to cure for a specified time to achieve optimal protection against water damage.
