I need to mount this IKEA magnetic knife rack onto a marble wall. Drilling is not an option.As you can see in the photos, the back of the holder is recessed. I tried using double-sided tape, but the gap is too wide. Layering the tape just caused it to peel off under the weight. Since I'll be attaching it directly to marble, what are my best options to fill that gap and get a strong, secure hold without drilling?
