Waterproofing spray is a protective coating designed to repel water from various surfaces. It is commonly used on materials like fabric, leather, and outdoor gear to prevent moisture damage. The spray creates a barrier that helps keep items dry, making it ideal for shoes, jackets, and tents. Applying waterproofing spray is usually simple; users just need to clean the surface, spray an even layer, and allow it to dry. Many products are available, each with specific instructions and drying times. Regular reapplication may be necessary to maintain effectiveness, especially after exposure to heavy rain or washing.
