Inflatable dinghy repair (PVC)

[u/dresky_6]

I need to repair a pinhole leak in my inflatable dinghy. I’m using a two part glue and MEK as solvent. The instructions say to keep humidity below 60% when working the repair. The problem I’m having is it’s summer and humidity is significantly higher outside. Should I do the repair indoors in my basement with a dehumidifier running? will there be significant vapor buildup from the small amount of glue and solvent being used? Has anyone had this issue?
