Glue for tarps?

[nopeda]

Hi,

I want to glue some tarp sections together and bought HH-66 and tried it out but it didn't stick at all. Then found out it works on vinyl but the tarps I'm using are polyethylene or polypropylene I don't know which. They are green on one side and brown on the other got at a hardware store and HH-66 doesn't work on that stuff. Can anyone suggest a type of glue that will work on it?

Thank you for any help!

I've never tried to join two sections of this kind of tarp, but perhaps sewing and then sealing with a Seam Grip product would be worth experimenting with? And / or using something like Gorilla Tape? Not sure if it would work or not. I might just go for a new larger tarp so I didn't have to worry about it. The only thing I've joined in this manner were two sections of a polycro / window insulation film groundsheet, which I was able to join with packing tape...seemed to form a permanent bond on that (wouldn't try that kind of a tape in your situation, however).

@Aaron Zagrodnick  Gorilla & Duct tape does work, but it is a temporary fix, and each time you retape it, previous residue left over has to be removed, so it is a pain in the arsh.  I used this method during a snowstorm in upstate NY at my families' off the grid log cabin so that I could lower the ceiling of the cabin by 10 feet, so that I wouldn't need as much wood, and could heat the cabin faster, as it was Cold  with a capital C.

primer Permabond POP with cyanoacrylate adhesives to bond polyethylene

SuperTAC 500 to bond polypropylene 

Other people have vouched for these, but I personally have not ever glued tarps together, only glued Mylar solar blankets over them for heat retention. 

I have connected two tarps using the gromets and paracord, and I have used Duct tape between two tarps to prevent the rain from creeping in, but if you want this to be permanent, Duct tape is not a long-term solution, and the more times you retape it, there will be leftover residue from previous tape, which will be a pain to remove.

The only real solution would be as Aaron had suggested, and sewing the two together, and using a sealing it with a seem product like Aaron initially suggested.

It may help if we knew exactly what you are using this for, to make a better determination for your resolve.
