It hasnt worked on anything I tried it on. The big pieces will not even hold light cork to my wall. Everything falls down. I had a picture that fell and broke the frame. DO NOT BUY. I have two boxes and they are going in the trash. How can they advertize such a product. Did they even test it? I had a 12X12 cork board and used UGLU on all four corners they had all fell down by the next day. I tried again with new pieces and using the larger pieces and it still was a mess. DO not belief these people.
