Fitting parts to a vertical surface without mechanical fixings

How do you fit parts to a vertical surface without the need for mechanical fixings or an extra pair of hands?

Easy you laminate it to an adhesive layer, only in this case the adhesive had to allow adjustments to the piece and not delaminate under extreme conditions. We achieved this by using a combination of adhesives to either side of a substrate, creating a high tack on one side and a low tack on the other, simple when you know how.
