A Brief About Rustoleum

Is Rustoleum Spray Paint Waterproof?Rustoleum started over a century ago in 1921 when the founder, Robert Fergusson, had to use fish oil to protect his ship from rust. He then went on to develop rust-preventive paints with the help of a chemist and this line of paints were the first of their kind.

It started with just 24 colors and today, Rustoleum is a global leader with multiple products to its name. From cleaners to coatings, primers, wood care, and enamel coating, you will find them all.

Is Rustoleum Spray Paint Waterproof?

Most of the Rustoleum spray paints are indeed waterproof. They form an impermeable barrier between the surface and the elements, creating a waterproof layer. These paints are made for both indoor and outdoor use and work wonders against water.

However, it is interesting to note that some paints may only be water resistant and not completely waterproof. This means that while they can withstand small amounts of water, heavy rain might wash them away. In this case, you will have to apply another layer of waterproofing paint. If you are using acrylic paint, for example, you must apply a sealer to make it waterproof.

Rustoleum spray paints that promise to be waterproof come with a whopping 15-year warranty. They also promise to protect against mildew and mold. 

One thing you should always remember is to let the paint dry and cure completely before any exposure to water. Wet paint is not resistant at all.
