VIKROMTent Seam Tape 65 Ft Lenght 0.8 Inch Wide Waterproof - White Tape Tent Repair Waterproof Seam Sealer

I needed to repair a friend’s snow pants that popped open at the seam in the back crotch.This tape worked perfectly for me :)I ripped out the lining seam larger than the outside seam that had pulled out. I sewed the outside seam and used a mini craft iron set at 2 of 4 and pressed the seam to the side using a silk transparent press cloth to protect the fabric on the seamline and the surrounding fabric :)This sealing tape wraps on the spool with the adhesive face down. I used a sleeve tailors ham since I was repairing the curved back crotch seam on a pair of snow pants. I used the silk press cloth. It is large so it protects all the fabric and is transparent, so I could see what I was doing.I centered the tape on the seamline and covered it with the silk press cloth.I counted 1,000 - 2,000 through 10,000 while applying pressure with the iron. I did one side then the other around the curve for each step.I set the timer on my phone for 3 minutes for not moving the fabric and allowing it to cool each section before moving to the next section. I double checked that the tape now looked almost transparent with no edges coming blisters Then I sewed the lining back together and was done :)

After 20 yrs my Kelty ZEN tent fly began to leak along some seams. Ordered this tape and the instructions say to apply with an iron. Kelty responded to my inquiry whether it was safe to apply with an iron with a pretty emphatic “no.” They said send the fly back to us and we’ll “see if we can help.” No time for all of that at the height of the season because who knows how long that’ll take, when I’ll get back, and at what cost? So, I have a commercial heat gun from when I was in the contacting biz. This tape is very thin but sticky so I just rolled it out along the seam and directed heat from the heat gun to the tape then pressed it into place without having to apply an iron directly to the fly fabric. The tape is really sticky when warmed up. I suppose you could even apply it with a household hair dryer. So far, so good. The tape is holding well. I did this by myself with one hand on the gun and the other rolling out the tape. If you actually had two people, one working the heat gun and the other applying the tape, this would be a super simple repair.

This is the worst product I have ever bought from Amazon, and that is saying a lot. The description states that it is suitable for clothing, and will not peel off during washing. It is not, and it did. When it was applied with heat it truned shiny, transparent, and stiff, like cellophane tape. After washing the garment, the tape is balled up and has removed parts of the lining, ruining the jacket.Edit: The company could not have been more responsive. They reached out to me offering a refund, and apologized for the incident. Based on their response, I will buy from them again.

Good product

Make no mistake, this stuff is tricky to use. You have to be really careful not to use too high of a heat setting, and to get it lined up exactly where you want it before you hit it with the iron. It's also a bit confusing which side of the role to use. I used heat setting 2 on my iron (your iron may be different), rolled the tape from over the top of the roll onto the seam of the rain jacket I was fixing. Then to get it to adhere I just touched it briefly with the iron all the way along the seam/seam take. If I tried to set the iron on the seam tape and "slide" it from one end to the other, it would pull it back up and cause it to bunch up. Don't try to do that. Just pick up the iron and touch it back down repeatedly until you've got it all adhered to the seam. That worked for me. I tried to iron it on through a towel, but it was not getting enough heat. Again, too much heat and you'll wreck your jacket. Although it took some time and careful application, I got the results I was after.

Low quality isnt perfect to seal

It was easy to apply to my old nylon kayak skirt seams. It seems to stick well.

It took me a little bit to get the temperature right but after that was dialed in I was able to reseal my old rain fly in a couple of hours. It would have been faster with a larger flat surface to work on. Putting cardboard under the fly really helped in the end.
