.... 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!

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

Many years I experimented with junk sails made from polytarp, the blue

"contact" cement is also called "rubber" cement

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