Without proactive maintenance, boat covers, RV awnings, pop-up camper tenting, cushions, upholstery and patio umbrellas can lose their vibrancy and impermeable qualities. Iosso Water Repellent is the easy way to protect outdoor fabrics against UV rays, dirt, grime, mold, mildew, oil, bird droppings and insect sap.

Iosso Water Repellent is invisible protection for Sunbrella and other technical acrylics, canvas, vinyl and leather. It isn't solvent-based and has no silicone, so fabrics maintain their vivid colors without darkening. They retain all their original breathability, flexibility and feel, without any residue.

Unlike some products, one-step Iosso Water Repellent is simple to use. It's sprayed directly onto clean, dry fabric and left to dry for 24 hours before exposing the material to water.

A 32 oz. spray bottle of Iosso Water Repellent covers approximately 37 sq. ft. and retails for $21.49; a one-gallon container treats up to 150 sq. ft. and costs $47.50. For large projects, Water Repellent is offered in a concentrated formula that's easily mixed with water.
