The fixing process itself is very simple as long as you can keep the nameplate in place and level until the adhesive holds (check the instructions for curing times) Choose a good brand of adhesive and be sure that it is suitable for exterior use.
Clean the back of your nameplate and the wall to remove dust and allow it to dry before trying to fix it.
