Thread Content

For repairing the bonding surface of rubber, fabric, fiberglass, polyurethane or other elastic substrates, you can use a low-speed sand disc grinder (24-50 precision sand disc) or a grinding steel brush (25 mm long, 100 mm in diameter) with an electric drill with a speed of less than 1800 rpm. Do not leave any bright spots or unsanded areas on the surface of the substrate as this will affect the repair bonding effect of the product. Use a clean, dry brush with detergent or other suitable cleaning agent to clean the sanded area. At the same time, the best bonding effect can be achieved by using adhesive together. After the adhesive solvent evaporates, it can be sprayed or poured. The area of ​​the repair material should always be larger than the actual repair area. The rapid repair glue can be completely cured within 2 hours at 21°C. At this time, the repair area can be polished. It is recommended to use a grinding wheel with an accuracy of 36 or 50.
