I started by painting the wall and the baseboard with the color intended for the whole wall.
Geometric Accent Wall
Give your wall some dramatic character with this easy to-do accent wall!
Using a stud finder, we marked where all the studs in the wall were using blue painter's tape.
We used 1"x2" furring strips. We measured the length of the wall where we wanted to place the first piece of wood. I recommend doing your longest lines first. Cut both ends of the wood at a 45 degree angle for the first board. Attach to the wall using a brad nailer/nail gun. Try to nail the wood in line with where you marked the studs in the wall. This will ensure the boards are nice and secure to the wall.
Continue to measure where you want to place the next board. Determine which end(s) will need a 45 degree cut. There is no science behind where you put your boards. It is totally up to you and what you think will look nice.
It is very important that you use a carpenter's triangle when you are lining up the boards to attach them to the wall.
If you use the triangle each time, you will ensure that there is a true right angle where each board meets another board and you should only have to do 45 degree angle or perfectly straight cuts.
Once all your boards are installed, paint all the boards to match your wall. I used a brush to paint mine and did two coats.
