The repellency effect has faded away or decreased – what do I need to do ?
After several washings, the repellency effect on textiles can decrease. In this case the textiles can be sealed again. Sometimes remains of washing agents can adhere to the textiles, which interrupts repellency. When the textiles have been treated with a strong washing powder, the repellence ability disappears, but the fibre protection remains. Through washing again with clear water and drying afterwards, the repellency ability will be re-produced. Before applying a sealant, wash the textiles only with water to remove any washing agents remains. The repellency ability can decrease through contaminants. In this case simply clean the surface with a mild cleaner and wash thoroughly. The repellency ability will then be re-produced. If the repellency ability cannot be re-produced, it can be a sign of a damaged surface.
