Spray product onto fabric until evenly wet, overlapping areas in a criss-cross pattern, and let dry. Do not oversaturate. Treated materials must be protected from rain/dew until completely cured. Cure Time: 12 - 24 hours dependent on temperature. If these steps are performed correctly, the material will be water repellent at this point. Re-application will be as needed, depending on fabric exposure to sunlight and weather conditions. To determine if fabric needs re-treatment, pour water on fabric. If water soaks into fabric, re-treatment is needed. Coverage: 40 - 75 square feet per 16 fluid ounces depending on material and application method.
