Otter Wax is an excellent way to waterproof untreated fabrics such as hemp. Rubbing the bar back and forth creates the perfect amount of heat to loosen wax and spread evenly into the top layer of fabric. Works best with natural fabrics, but can also be used on blends when natural fabrics are in the majority. - Thoroughly clean and dry item before application - Rub into fabric to create friction - Smooth out with fingers to create uniform seal - Allow item to cure in a warm, dry place for at least 24 hours - Reapply as often as necessary
