GA REVIVEX SUEDE + FABRIC WATER REPELLENT is a spray treatment for footwear with leather and textile uppers. The product does not discolour leather and maintains the original matt appearance of nubuck and suede. However, it should be used more frequently than creams and gels, at least once every week of shoe use and always when drying wet shoes. The product is environmentally friendly, containing no PFAS fluorocarbons. Instructions. After a light spraying, wait until the liquid has soaked into the material to be treated (leather, fabric) and then repeat the spraying once more. Working the liquid into the leather by hand helps speed up the process. The footwear is ready for use after the spray has dried, which takes several hours. It is best to treat the shoes in the evening and allow the spray to soak in and dry overnight.
