Waterproof Spray

Waterproof spray is a coating that seals out moisture. Sprays often are made with a silicone or fluoropolymer base, both of which are effective waterproofing ingredients that generally won't stain or leave a permanent unpleasant scent. Sprays are often used to waterproof clothing for outdoor use; camping equipment, such as sleeping bags; and outdoor furniture. It may also help fabrics repel stains from spilled food or drink. Carpets and furniture, for example, are commonly treated with waterproof spray to keep them from absorbing liquids that may stain them.

Silicone spray is most commonly used to protect indoor and outdoor fabrics. It is relatively harmless, typically has no odor, and is generally easy to apply. Silicone is highly resistant to water; in addition to treating fabric, this spray also may be used to waterproof brick patios, concrete pathways and wood decks. Aresol sprays are typically used for clothing and furniture applications since they help keep fabrics dry, though multiple applications may be required for the best protection from water. Experts generally recommend letting items dry for up to 72 hours after the spray is applied to ensure that it has set completely.
