Many years I experimented with junk sails made from polytarp, the blue
stuff, and contact cement worked fine.

Hi all!

Is there a glue that will work on polyethylene tarp material? Often
I'd like to make patches to secure rips so that they don't get larger,
but no glue I've tried seems to "melt" the tarp material to
form a good bond.

Is there a glue that will work?

thanks!

Hi Jacques!

Contact cement - good idea. I'll give it a try.

thanks

"contact" cement is also called "rubber" cement

people who make polytarp sails also bond by heating with a hot iron.
never tried it myself.

NO, contact cement is NOT rubber cement. Contact adhesive is contact
adhesive.

.... and will pull apart with very little stress. Polyethylene is notorious
for having a surface that nothing will stick to. You can heat weld it, but
it's beyond most non-commercial applications. It takes specific heat,
pressure and dwell times, done either by bar sealers or "doughboy"
continuous band sealers. You can try any glue you want, but I can tell you
from years in R&D in the plastics industry, there is nothing that will work
well with PE. Best bet are those tapes mentioned earlier, used on both
sides. Duct tape will for for a few weeks, but weather and UV will tear it
up pretty fast. Really... those blue poly tarps cost what... $5-15? Replace
it if it's gone!

I can't remember the brand name. That happened in Haiti 25 years ago and I
used some german contact cement that I had on the boat.
It worked relatively well but I remember that we had to press the glue line
down under a 2x4 then hit with a hammer . . . all fine sailmaking skills . .
