best tape or glue

hey guys just looking for some good products like double sided tape/glue/caulk to hang white black mylar im in a 10x12x8 room and im trying to make it air tight trying to avoid staples but will use if necessary maybe squirt silicon over them any ideas would help thanks guys!

Go to home depot. Look for gorilla tape gorilla glue and industrial strength velcro. You can buy it by the 25 foot roll for the velcro. I used mostly velcro squares all across the ceiling and walls to hang mine. Then went back with gorilla tape around all the edges to seal it. Could also use a staple gun.

See my journal for how i hung my panda film tarp doorway.
