Hey guys,
I'm not sure if anyone has dealt with this before. Given that my game room is in the basement, the two open walls are concrete. It limits my means of hanging stuff up as tape doesn't stick in the least and I tried some putty-like stuff that refused to bond at all. That stronger white double sided tape has begun to give out as well.
Nails and such really aren't an option, so I'm running out of ideas. I'm open to suggestions here, if there are any.
