We all know that repairing things is really cool, but where does one start? With teamed up with Snowdonia Gear Repair to bring you a series of quick repairs you can do yourself. Keep reading for a step by step guide to heat patching a tear in a bike bag.

When to heat patch a bike bag:

The tear is shorter than your thumb
Minimal fabric is missing
The bag is too tricky to sew

You Will Need:

Neoprene heat patch, or tenacious tape
Scissors
Heat source (iron, hair dryer, or heat gun)
Parchment paper
Seam grip

Step 1:

Choose your tape. We prefer neoprene heat tape for its durability and waterproofing.

Step 2:

Cut your patch. Make sure it’s big enough to cover the tear with at least a centimetre extra on each side. Round the corners with scissors.

Step 3:

Smooth the torn area to the best of your ability. If it won’t sit flat or has a rigid structure, consider using a tailor’s ham or stuffing it with spare cotton clothes.

Step 4:

Set up the patch where you want it to sit, then spread a piece of parchment paper over the area.

Step 5:

Apply heat to the patch for 5-10 seconds on a low temperature. Press the patch into the fabric. You want it firmly stuck to the bag with corners and edges sitting flat. Take care not to melt any surrounding plastic features on the bag. Incrementally increase heat if the patch isn’t adhering.

Step 6:

Cool to room temperature.

Step 7:

Squeeze a thin line of seam grip around the edge of the patch. Use a small brush or a toothpick to smooth the seam grip over the edge of the patch and surrounding fabric.

Step 8:

Allow to dry for the time indicated on seam grip packaging.

Step 9:

Pat yourself of the back. You’ve just repaired your bag!
