Use adhesive to secure the metal panels to the backsplash area. Be sure to use an adhesive that will adhere to the metal panels and to the wall surface where the panels are to be mounted. Use just enough cone head nails to secure the panels to the wall while the adhesive sets up. Do not remove the nails. Follow the adhesive manufacturer’s instructions for proper application. If desired, you may place additional cone head nails for a preferred visual effect.
