What is Seam Sealing Tape?

Engineering & Manufacturing Specialists since 1973

While advances in fabric technology has produced water repellent and waterproof fabrics that can be used for Tents, Jackets and so much more, there is still vulnerabilities in the stitch holes that are created when seams are sewn into fabrics.

Whether this is the seam join between a jacket sleeve and jackets main body panels or two panels of a camping tent, it still creates an entry point that water can penetrate.

To prevent water from entering, seam sealing tape can be applied to seal up these vulnerable stitch holes and make the fabric seam waterproof.

So what is seam sealing tape?

Seam Sealing Tape is simply an adhesive tape that is used on seams of clothing and other manufacturered products to prevent humidity and water penetration whilst adding strength to the products seam joint.

There are three main types of seam sealing tapes used in manufacturing and garments.

Single Layer Seam Sealing Tapes

Single layer seam sealing tapes are only activated by heat to weld onto PU coated fabrics.

2 Layer Seam Sealing Tapes

A 2 layer seam sealing tape is commonly used to prevent water penetration over stitch seams and is commonly found in the likes of Waterproof jackets.

3 Layer Seam Sealing Tapes

Similar to 2 layer seam sealing tapes but with a thicker and more heavy duty design that makes them ideal for use in more demanding environements such as military application, medical wear, the automotive industry (for the likes of car seat seam sealing and dashboards), dry and wet suits and PPE Clothing.

A tent with leaky seams is no fun, especially amid that afternoon downpour. But a tent’s seams are also its most vulnerable zone to rogue and insistent water.

To prevent infiltration, tent manufacturers have three options: seam taping, seam sealing, and creating a strong seam construction itself.

Since you’re reading this, you’re probably curious about difference between these solutions. And, whether one is better than the others. Let’s dive in.

Seam taping—what is it?

MSR Blog Seam Taping vs Seam Sealing Tent Care 101

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.

On new tents, if done well, the tape is hard to see, so you might not even know it’s there.

Seam sealing, on the other hand, is like applying a layer of glue—or sealant—across the seams.

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.

When painted on, the sealant seeps into the stitching holes, creating a waterproof barrier.

Is factory seam taping good enough?

First, let’s ask: Have you ever experienced a tent with flaking seams? If so, you’re not alone. Seam tape works really well in some applications and less so in others.

On heavier-weight tent fabrics—about 68 Denier and above—seam taping is an excellent solution. That’s because the tape adheres to these fabrics well, holding tight for long-term protection.

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. And once the tape goes, your seams are defenseless. Sometimes seam-sealing offers a remedy, but oftentimes the residual tape interferes and causes a headache.

At MSR, we’ve always used the highest quality fabrics, 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. Now in 2019, we’re excited 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.

Should I seam seal my 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.

If your seams are stitched and factory-sealed, as in the case of MSR’s Hubba series, but over time wear has exposed areas to leaks, seam sealing is much easier to do.

Do you seam seal inside or outside of the tent?

Apply the sealant to the underside/inside (or shiny side) of the fabric.

Best tent seam sealers?

We’re gearheads and have tested the array of seam sealants out there. Gear Aid’s remain the best. For the most bomber one, go with Seam Grip +WP. You can apply this once and be set for many years—we’ve heard decades. It does require a little effort and a longer dry time than others.

For the easiest application that still provides long-lasting performance, use the Seam Grip +FC Fast Cure Sealant.

Often, just sealing up the sections where you’ve noticed drops, is sufficient.

Like any piece of high-performance equipment, your tent requires some care (use these tips). But, a little TLC can go a long way toward maintaining its quality.

Now, enough tech talk… We think this technology can—and should be—in tents!

Seam Tape How-To

This tip is meant as a short tutorial on seam tape and how to apply it in your sewing projects. Seam tape is one method to stop water from coming through the seam and needle holes made when sewing coated waterproof fabrics, such as Gore-tex, Finlayson Action, Ultrex etc. Seam taping is not necessary on water-resistant and fleece materials, as water will come through the fabric before the seams. Of course, if not interested in 100% waterproofness then tape can be left away, but then you might as well use a more breathable, water-resistant fabric! Cheaper and less sweaty. Tape comes typically in widths of 20-25 mm, but is sometimes available even in 50 mm widths. A heat activated adhesive is on one side, and a waterproof membrane on the other. Seam tape for three-layer materials is special as it also has a fabric layer to protect the tape and reduce friction. The adhesive layer is also thicker so it fills the more porous inner surface of 3-layer fabrics when attached. When possible, it is best to use tape from the same manufacturer of the fabric being used. This usually gives the best result.

The easiest way to include seam tape in your project is to apply it each time you finish a seam. Trying to apply tape after your project is finished is very difficult. Now we will walk through some basic instructions for tape. Straight seams are easy, curved seams more difficult. Be prepared to spend some time here.

    Instructions
  • You will need a basic clothes iron, a table or preferably ironing board, and some baking paper. Using the baking paper between the tape and iron avoids getting sticky glue on your good iron! Baking paper may not be needed for 3L tape. About 80 deg centigrade is enough for 2L seam tape, and around 125 deg for 3L. This is setting 1-2 on many home irons, but experiment to get it right. Be careful not to melt your fabric.
  • First cut any excess seam allowance so that there is more area for the tape to stick to. Cut a piece of tape a bit longer than the seam.
  • One side of the tape has a layer of adhesive, this side is placed against the seam.
  • Place the tape centered on the seam, adhesive side down. Starting from one end, place the baking paper over the tape and heat with the iron for a few seconds, then lift. You should be able to see that the glue is melted and the tape is in place. Otherwise you should try heating longer or with a higher heat setting. Move along the tape, not sliding the iron but lifting between sections. After the whole seam is done, go over it again to be sure it is secure. You may need to iron each side of the seam separately.
  • Curved seams are more difficult. Usually making small cuts in the edges of the tape will help around curved.
  • Once tape is applied, don't try to pull it off, you may damage the fabric's coating. Over time seam tape may start to leave from a seam, this can be fixed by re-heating the seam - but usually correctly applied tape is very durable. After letting cool completely, check your tape again make sure you have good adhesion.
