First, measure the length and height of the wall to establish the main dimensions. Then, sketch a few design ideas on graph paper and decide the pattern you want for your accent wall.
Use a software like Sketch-Up to create a final design mock-up of the wall.
By inputting the main dimensions into the software, we were able to have the computer calculate the measurements for each individual board. Then we cut them using a miter saw.
Start by installing the first board (base piece) at the bottom of the wall, just above the existing trim in the room.
Next, install the main diagonal, which is the longest board and serves as a guide for the rest of the accent wall installation.
Continue installing the remaining boards on your wall according to your design plan.
Fill all of the nail holes with wood putty. Then caulk the gaps between the wood pieces and the wall.
Once the caulking and wood putty has dried, the entire wall can be painted. Be sure to wipe all of the dust from the wall before you start painting.
