Cf uses a glue that is normally used to hold cars and airplanes together - it's an entirely different material. Sewing it would actually weaken it (think of it as sewing milk bags vs gluing them).Originally Posted by fallkniven

While that is true to an extent, the strongest tie outs are bonded and sewn. If you are really averse to sewing you could tape grosgrain onto each side of the tarp and then bond a cuben patch on both sides. I would use a pressure roller to put sufficient pressure on the bonded areas. This type of tie out would most likely be strong enough to avoid sewing.

I'm glad you linked to Sgt. Rock's guide. I hadn't seen it before, and he does a great job of explaining this bonding process in detail. It happens to be the same one I use.
You can glue the tieouts, but you need to make them strong enough. Using the same thickness cuben as the tarp. I had to use several layers to hold a 2" dowel to the tarp edge. Then I poked a hole in the tarp just inside the dowel so I could fasten the guy line to the dowel. I could have used a heavier grade of cuben, but I didn't have any. I have also sewn grosgrain loops to stronger cuben reinforcement patches, then glued them to the tarp and finally glued a slightly larger cuben patch over that.
As Sgt. Rock notes in the video, you let the primer dry before you use the VHB tape over it, so no problem with working quickly.
Absolutely! I have never seen a VHB bond fail. This is not ordinary tape. In fact, it's not even "tape" in the sense that you're probably thinking of - just a thin layer of adhesive between two kraft paper backing strips. (This also makes it much lighter than conventional tapes.)
Thanks! That's really helpful - I completely forgot about the part where he said to let it dry, it's a really long video.
How about that. You can tape a tarp together. Is it pretty straight forward?
Yup, but not cheap.
You can see my latest cuben tarp in this thread. The video in the first post is pretty long, but if you jump to the follow-up video in post 24 you'll see how easy it is to modify a cuben tarp.
ah cool. I'll have to watch that this weekend. I did notice that cuben fiber is quitte pricey, but you could probably make a gigantic tarp if you wanted with that stuff being so light and compressible.
Excellent.
