Shake the bottle vigorously. Holding the bottle 6 to 8 inches away from the surface, spray in an even crisscross pattern. Two to four applications may be required. Allow 1 hour to cure between applications. Waterproofing improves and lasts longer with multiple applications. After final application, rinse out the sprayer by pumping hot water through it to avoid clogging.
Water Shield waterproofs most fabrics and suede. It can be used on smooth leather as an extra protection, however, apply only after Obenauf's leather preservative. Test in a hidden area if color change is a concern.
