Rinse completely and hang to dry or tumble dry before use. Wear gloves to protect your hands. Spread the clean rug on a surface that is free of dirt or debris. Wet the rug first with plain water if it is still not damp from cleaning. It is very important to use a new sponge or one that is dedicated only to this purpose.
Old sponges retain detergent residue that can spoil the waterproofing.
Apply the diluted solution with the sponge, working well into the fabric. Pay particular attention to all seams and the middle area of the back. Turn the rug over and treat the other side. When the rug is completely covered, apply a second coat to the middle area of the back on both sides. Do not use the sponge for any other purpose.
