Recommended by the manufacturers of Sunbrella to restore water repellency to your outdoor performance fabrics. Made in the USA, safe for all fabrics.
Instructions: Use only on clean, dry fabrics. Test for colorfastness. Spray 303 Fabric Guard onto fabric until evenly wet, overlapping areas in a criss-cross pattern, and let dry. Treated material must be protected from rain/dew until completely cured, 12-24 hours depending on temperature. If applied correctly, the fabric will be water-repellent after curing.
