Got a puncture in a Synmat Basic 7.5 and patched per instructions.
Testing showed the Patch was leaking directly over the hole.
Pulled the patch, cleaned with care, applied new patch and copious glue from a new tube of glue.
The mat was Completely deflated, and both ports left open.
Drying time was about 6 hours.
Testing shows the second patch is also leaking directly over the hole.
An email to Exped hasn't produced anything yet (it's sunday).
Insights?
Thanks.
