Use a chalk line to make a grid to guide you to an even layout of your tiles.
Apply construction adhesive to the back of the tiles according to the manufacturer's specifications. Install the first row of tiles then move on to the next, overlapping the panels; be sure the tiles overlap away from the main viewing area. Use full tiles for most of the backsplash to limit the number of cuts you will have to make.
Use the tin snips to make any necessary cuts to the tile. Be sure to wear heavy-duty gloves while cutting since the tile edges will be very sharp. Be careful when applying tiles around outlets to ensure that none of the metal comes in contact with the wires. Better yet, turn off the electricity to those outlets to prevent accidental shocks
The panels can be painted or left unfinished in bright tin depending on your preference. If you choose to paint them, use a bonding primer that will adhere to metal, then finish them with an oil-based paint. If left unpainted, coat the tiles with a clear lacquer or polyurethane. When applying polyurethane, use a lamb's wool applicator to finish the tiles.
