    Usage Directions: Use only on newly, cleaned, dry fabrics. For best results, treat fabrics in warm weather, of at least 70 degrees or warmer. In a well-ventilated area, spray 303 Fabric Guard on fabric until damp, overlapping in a crisscross pattern. Do not saturate. Let dry for 6-12 hours in a clean, dry environment before using or storing. Treated material must be protected from rain/dew until completely cured. If these steps are performed correctly, the material will be water repellent at this point. 303 Fabric Guard will need reapplication depending on fabric exposure to sunlight and weather conditions; pour water on fabric to determine need to retreat fabric. Coverage: 75-100 square feet (7-9.3 m²) per 16 fl. ounce (473 ml) on lightweight fabrics; 40-75 square feet (3.7-7 m²) on heavier fabrics depending on material and application method.
