5 Reasons Not to Use Duct Tape for Tarp Repairs… And What You Should Use Instead

Many people assume that duct tape is the perfect tool for tarp repairs, but unfortunately the results are often disappointing. Although duct tape is useful for a range of repair jobs, for tarp repairs it's much better to use tarp tape. This strong, cloth-backed tape can produce repairs that are durable and weather-resistant. Here are the five main problems with using duct tape to repair your tarp.

1. Duct Tape Repairs Aren't Durable

Although duct tape is waterproof, it doesn't stand up well to other extreme weather conditions. Unlike tarp tape, which is resistant to UV rays, duct tape's lifespan can be shortened by prolonged exposure to bright sunlight. Duct tape is also brittle when it gets very cold, which means the repair can break. These properties are problems for canvas cover repairs that need to last all year round.

2. Duct Tape Doesn't Stick as Well as Tarp Tape

Duct tape is designed to stick to hard surfaces, such as metal or plastic. Its ability to adhere to tarpaulin is limited, which means that you may find it peeling away from the canvas if you use it to repair your tarp. Tarp tape, on the other hand, contains an adhesive that is designed to provide a strong bond with canvas. Therefore, it's the best choice for canvas cover repairs.

3. Duct Tape is Vulnerable to Rot

Although duct tape is initially waterproof, as the adhesive begins to break down water can get into the repair and lead to rot. If you notice your repaired tarp starting to smell bad, it could be because you used the wrong kind of tape to carry out the repair.

4. Duct Tape Isn't as Flexible as Tarp Tape

Tarp tape is designed to be just as flexible as canvas, but duct tape doesn't offer the same mobility. If you try to fold a piece of tarp that has been repaired with duct tape, you may notice that the tape wrinkles or cracks, rather than stretches and bends with the material. These deformations of the tape can create weaknesses in the repair job, leading to the tarp losing its water resistance or even tearing again.

5. Some Repairs Need More Than Tape

For larger repair jobs, it's likely that neither duct tape or tarp tape alone will be enough. You may need to sew the edges of the fabric back together or patch the tear using a spare piece of canvas. These methods can produce a strong and reliable repair.
