I bought the tape to above the skirting board to attach a cable duct with approximately 6mm footprint on the wall in his study. Holes I did not want to drill and, of course, the adhesive surface of the bar itself did not on the rough ground. At some points I had to help out while selectively with some superglue, but that was foreseeable and unproblematic due to the subsurface. Overall, a clean and uncomplicated solution that has withstood subsequent purification attacks with a vacuum cleaner!
