Is rustoleum paint waterproof

Rust-Oleum paint is designed to be water-resistant, but its waterproof capabilities can vary depending on the specific product and the surface it’s applied to. Many Rust-Oleum paints provide a protective barrier against moisture, making them suitable for outdoor use and areas prone to humidity. However, for complete waterproofing, it's essential to follow the manufacturer's guidelines and consider using a sealant or topcoat for additional protection in high-moisture environments.
