A dual-adhesive double-sided adhesive tape, having a first double-sided tape that includes a first adhesive on each side of a first support and a second double-sided tape that has a second adhesive on each side of a second support. The first double-sided tape is attached to the release layer of the second double-sided tape. This dual-adhesive double-sided adhesive tape can be simply made by joining the first double-sided tape to a release layer of the second double-sided tape. The dual-adhesive double-sided adhesive tape of the present invention is suited for use in a method of mounting an article on a working surface. The article is provided with the dual-adhesive tape with the release liner of the first tape being removed so that the article can be temporarily mounted to determine the correct location before mounting the article by the second tape.
