Seam tape is just what its name describes. It’s a layer of tape technically, a polyurethane film that is placed under the seams to block any water that enters the needle holes from making its way into your tent. The tape acts like dam.Seam taping can only be done at the factory because it requires a special machine, and each type of fabric demands an exact temperature for application. Tent factories are typically certified to apply seam tape.You might be familiar with the seam tape on your waterproof jacket. In tents, the method is similar, but the way it’s integrated is different.

Some tents, such as select tents from MSR, come seam sealed from the manufacturer.Seam sealing is also something you might do as your tent ages and start to you notice leaks. If the rest of your tent is still in good order, seam sealing is great way maintain it instead of buying a new tent.You might do it if your new tent didn’t come taped or sealed and you want the extra measure of defense before you head out in particularly foul weather.But on lightweight tent fabrics, this is less so the case. On thinner tent fabrics, the tape simply degrades faster.

It works great early on, but over time with exposure to moisture, heat and humidity, the tape can start to breakdown and flake off. This can take several years if you take great care of your tent, or it can happen relatively quickly if you don’t. Storing your tent damp is the worst culprit. waterproof coatings and tape formulations. But as tent fabrics have gotten lighter, we found that even the best seam tape didn’t meet our standards for long-term performance. For 10 years, we’ve been researching a solution to this seam tape challenge on lightweight tents.

We’re excited Sealing Tape to expand our new Xtreme Shield waterproof coating which brings with it, precision-stitched, factory-sealed seams. This seam construction is far more durable than traditional taped seams, and can be maintained over time so that you can ensure your seams stay watertight for the life of your tent.The easy answer is, if it leaks, yes. Seam sealing will create a waterproof barrier and extend the longevity of your tent. If your seams came taped from the factory, this might be tricky to do as any residual tape can disrupt the application.
