I want to put a cork bulletin board outside my store but it's a cement wall and I do not want to ruin the cement wall.
I tapped some nails in. But I don't recommend it. It took a long time and you'll probably get charged for the damage it does to the paint. I found some sticky, puffy stuff from Duct Tape. It's double sided and it's waaaay sticky. For my heavier stuff I just doubled/tripled up and it hung right up. This is what I did for my full length mirror. Also they make those clear plastic holder things. I'm sorry, I'm not sure what they're called. But they have sticky on one side and you stick that to the wall and then there is a hook on the other side. They work great too and are cheap!
go buy a tap con kit. It consists of a drill bit for the concrete, concrete screws and a driver. It should only cost a few dollars. drill pilot holes in the cork, drill the concrete and fasten it with the blue screws made for concrete, you may want to paint the screw heads to blend afterward.
You could try the self-adhesive hooks from 3M, but not sure how well they will stick to cement.
Use construction adhesive such as PL400 or Liquid Nails. If you ever need to take the board down, use acetone to soften the glue and and use a putty knife to peel the glue off, any remaining glue can be wiped off with a rag and acetone.
The problem your going to have is making it secure without damaging the wall. The construction adhesive ideas will work but if you take it down the wall will be covered with glue and cork. Very hard to remove. Rambo has a less destructive idea, though I think I would put a wooden frame around the cork and screw the wood to the wall. IF you had to take it down all you would need to do is fill in the screw holes. Is there anything wooden above the board location where you could hang the board from on chain? That would be the best approach if so. If you need help with it....call me. I'll be right over. LOL
