Because trampolines are often kept outside uncovered, exposure to the elements can result in a damaged mat. A mat that has been battered by the weather may become weak and susceptible to rips and tears. You can repair a tear in a trampoline mat as long as it is less than 2.5 cm (1 inch) wide.
Inspect the surface of the jumping mat to find all areas that might need to be repaired. If the tears are more than 2.5 cm (1 inch) wide or there are many tears, replace the entire mat. Before taking the jumping mat off the frame, mark the tears with a piece of duct tape.
Remove the trampoline jumping mat from the frame by removing the springs from their frame holes. Be careful doing this, as the springs are tight and may not come out easily. To speed up this process, get friends or family members to help.
Lay the mat flat on the ground and make sure the tape marking the tear is still in place. Measure the tear so you can cut the proper size of mat repair fabric. The repair material should be cut to double the size of the tear.
Cut two pieces of the same size, as you will "sandwich" the tear with repair material, with one piece on each side of the torn mat.
Sew the repair material to the torn mat with a sewing machine or other sewing machine that can handle thick nylon thread.
Load the nylon thread on the sewing machine as you would regular thread. Pin the repair material to each side of the jumping mat around the tear to hold the repair material in place while sewing. Sew around the edges of the repair material; to ensure a firm hold, sew around the edges twice and across the middle of the tear.
Place the mat back on the springs and frame. Test the stability by jumping on the trampoline a few times before allowing children or adults to jump on it.
Fold the mat to make it easier to carry it to where it will be repaired.
To keep damage to the jumping mat at a minimum, invest in a trampoline cover to prolong the life of the mat.
If the repairs do not work or the repair material comes loose from its stitching, it might be wise to take the jumping mat to a professional to have it repaired.
Once a tear is found, make sure no one jumps on the trampoline. Doing so could result in injury or worsen the tear.
