303® Fabric Guard

303® Fabric Guard is a professional-grade spray-on protector designed to restore and maintain water repellency in outdoor fabrics. Engineered for use on both synthetic and natural fibers, it safely repels water and protects against both water-based and oil-based stains—without altering the color, feel, flammability, or breathability of the material.

• Restores lost water repellency to factory levels
• Safe for use on outdoor synthetic and natural fabrics
• Protects against water-based and oil-based stains
• Maintains original fabric color, feel, breathability, and flammability
• Recommended by Sunbrella®, a leading outdoor fabric manufacturer
• Covers 40–75 sq. ft. per application (coverage varies by fabric and application method)

Typical Applications

• Convertible tops (prevents seam wicking)
• Outdoor rugs
• Patio furniture covers and cushions
• Umbrellas

Usage Directions

1. Apply to clean, dry fabric above 70°F (21°C) for best results. Application in full sun will speed up drying and curing.
2. Spray evenly, overlapping areas to ensure complete coverage.
3. Keep product and treated fabric away from heat, sparks, open flames, and do not smoke during application. Both liquid and spray are flammable until fully dry.
4. Allow to cure for 12–24 hours, depending on temperature. Protect from rain or dew until fully cured.
5. Test water repellency after curing. Reapply as needed based on exposure to sun and weather.
6. Note: Reduced coverage if applied with roller or brush.

Example Use Cases

• Patio Cushion: Untreated cushions absorb water and stain easily. Treated with 303® Fabric Guard, water and soil repel from the fabric, extending cushion life.
• Umbrella: Untreated umbrellas stain from rain and outdoor elements. Treated with 303® Fabric Guard, water and soil are repelled, keeping the fabric cleaner and protected.
