I cannot find 1/2" corkboard around here and had to put 2 layers of 1/4" on a wall above my desk. The wall is painted and textured I used 2 sided carpet tape and the 2nd layer was staggered from the 1st. After 2 days, the whole thing came unstuck from the wall but the 2 layers of cork were still stuck together. What is out there that I can use to adhere the corkboard to the wall yet if I decide to take it off years from now I won't have to tear off the drywall?
