We have tried: We repaired a tear in the nylon fabric with a self-adhesive patch. The patch sticks perfectly to this material (it is important to carefully follow the instructions for applying the patch). We soaked the repaired fabric in water and washed it gently at 30°C, the patch holds after washing. It is suitable for repairing tears and small holes in tents, backpacks, sleeping bags, etc.
User manual: Vinyl material is great for repairing cracks and holes, it is easy to use. 1 - clean the area to be repaired and make sure it is dry. 2 - cut the required size from the patch. 3 - place the patch over the hole / crack and press it firmly. 4 - wait 30 min. until it sticks properly.
