First start with faux brick panels from the hardware store. I used 4'x8' sheets.
Next measure the length and height that each panel will need to be cut to.
Now, mark the panels to correct size to be cut and cut them with the saw of your choice. I used a jig saw and a table saw to make the cuts.
Cutting the panels to size is a little like a game of Tetris. You may have to waste cut a few rose so that they line up when the are hung end to end (side by side.)
I found it easiest to lay the panels flat on the ground in a line as I cut them to make sure they lined up exactly.
Next, you need to take the panels in and mark where notches may need to be cut in order for the panels to fit under the cabinets.
I just used the table saw to cut back and forth to make a notch in the panels.
This next tip is super helpful for cutting the holes for the outlets! Take a tube of toothpaste and squirt a little on the corners of each outlet. Then slide your panels into place. Then remove the again and the toothpaste will have transferred to the back of the panel showing where you need to cut the hole for the outlet. To get the exact size of the cut needed trace the outlet cover and then cut your hole slightly smaller.
To cut the hole for the outlet first drill pilot holes in the panel and then use a jig saw to cut along the outline that your drew with the outlet cover.
Now, your ready to set your panels in place. First, put construction adhesive on the back of the panels and then press them into place. Use a nail gun or panel nails to attach the panels into place.
Don't worry if you have gaps or spaces between the panels. It will be covered up in the faux finishing process.
The first step of the faux finish is to sporadically paint some of the bricks white.
Then go in and paint some of them a taupe/tan color.
Paint a few a light gray and a few dark gray.
Before the paint is completely dry use a wet rag to rub and blend the paint on each brick.
Then, take the drywall spackle and trowel in very thinly all over the brick.
Lastly, take the grout and using your fingers fill in all the lines where the mortar would be present and any gaps in the panels. I tried several other ways to apply it, but just using my fingers seemed to be the easiest.
To wrap up, caulk around all edges and replace any outlet covers.
