How to Install an Aluminum Backsplash

Measure the dimensions of the area you wish to cover with the aluminum backsplash and have a piece of 1/4-inch plywood cut to those dimensions.

Line the wall where you plan to install the backsplash with the piece of plywood. Apply wood glue to the back of the plywood and press into the place on the wall then secure it in place with nails from a nail gun.

Remove your aluminum backsplash panels from the package and lay them on a flat surface. If any of the edges are distorted, tap them lightly with a hard rubber mallet.

Determine how many panels you will need to cover the desired area by dividing the length of the area by the width of a single panel. This will give you an idea whether you will need to cut the panels on each end or not. If it turns out that you do need to trim one or more of the panels, draw a straight line on the back of the panel with a felt-tip pen and cut along the line with tin snips.

Apply a layer of latex-based tile or panel adhesive to the first 12 inches or so of the plywood. While it is still moist, place your first panel into position, aligning the edges of the panel with those of the plywood.

Press the panel into the adhesive, allowing it to spread and fill in any embossed areas. When the adhesive hardens, it will help to protect the panels against dents. Hold the panel in place for two minutes, or longer if the instructions included with the adhesive recommend it.

Place the next panel so that it overlaps the edge of the first by 3/8 of an inch. To prevent moisture from seeping through the space between the overlapped edges, apply a thin bead of clear silicone sealant before placing the second tile then wipe away the excess after the panel is in position.

Spread more of the adhesive as needed and place the remainder of the panels by following the same procedure. All panels should overlap by 3/8 of an inch -- this includes the top edges if you have to use more than one row of panels.

Apply a bead of silicone sealant all the way around the edges of the finished backsplash to prevent moisture from getting in behind the panels. Wipe away any excess sealant.
