Temporary repairs to gear

When fabric is under tension, the force is spread across all the threads. A tear interrupts those threads. The force now has to go around the tear, and at its end it concentrates on just a few threads. Those threads are overloaded and break next – that is how a tear travels. It happens to tarps in the wind and to backpack fabric under load.

A good temporary fix takes that tension off the ends of the tear. Tape applied over a large area and well beyond the ends spreads the force onto intact fabric. A seam that runs a little past the end does the same. On straps, a long overlap joined with many stitches or several wraps of cord helps.

Tape itself also has a weak point: its corners. A sharp corner is where tape starts to peel, because the force acts on a small area there. Rounded corners therefore hold much longer. On tarps and jackets it is best to tape both sides so the fabric is sandwiched in between.

Tape only sticks well to clean, dry surfaces. Wipe the spot, dry it with a cloth or let it dry briefly. Tape sticks poorly in the cold; warm it first in a jacket pocket or against your body. Then press it on firmly and rub your fingers over the whole area so the adhesive makes contact everywhere.

With a torn strap, let the ends overlap generously and sew them together with strong stitches. Without a sewing kit, wrap the overlap tightly with cord and knot it, or join it with two cable ties. With a broken zip, safety pins close the open sections; a loop of cord replaces a snapped zip pull.

A loose shoe sole is tied on with tape or cord wrapped around the whole shoe. Make sure no knots or thick bulges press on your foot. Then walk on slowly – and have the shoe repaired or replaced soon. Check every temporary fix at every break and touch it up before it fails.

Temporary fixes make sense on tents, tarps, jackets, backpacks, bags and shoes – everything that keeps you dry, warm and mobile but does not secure your life. Here a quick repair is often the difference between an uncomfortable night and a dangerously wet one.

Safety-critical parts are not patched: stoves, gas hoses, cartridges, batteries, power cables, climbing and safety gear, and medical aids. With these parts, a failure can cause a fire, poisoning, an electric shock or a fall. The right approach is: retire the part and carry on without it, or turn back.

A temporary fix also never stays permanent. After the trip the gear goes to a professional, gets sewn properly or is replaced. Adhesive residue cannot always be removed cleanly, by the way – that is the price of quick help.

The biggest hazard when repairing on the move is usually the knife. Always cut away from your body, keep your other hand out of the cutting line and fold or stow the knife immediately after the cut. When you are cold and tired, cuts happen especially easily.

When sewing thick materials such as webbing, a thimble or a piece of leather protects your finger from the needle. And with cable ties: never put them around body parts.

Also think about what happens if a fix fails. A patched shoe gives less grip on wet rock, a taped tarp can rip open again in a storm. Plan for these weaknesses: walk more slowly, adjust the route, and turn back earlier if in doubt.

Survival manuals have described for decades how to maintain gear with materials you carry. Modern gear has become lighter and more delicate, but the principle has stayed the same: with a few basic materials most damage can be bridged until the next workshop.

A common misconception is that tape fixes “everything”. It is an excellent tool for surfaces, but weak in wet, cold and under constant pull. For straps and seams, sewing is often the better choice, and cord for loose parts. If you know all three methods, you can pick the right one for each kind of damage.
