When you are looking at creative wall painting ideas to refresh the look of your living room, it's not easy to decide on a specific look. That's why a minimalist geometric wall is an excellent choice as it can easily blend into the décor without overpowering the room. The DIY accent wall feature that I will show you how to paint is easy to do. The stylish triangle painting is sure to elevate the style of your home.

Step 1: Prepare the wall for the geometric wall painting

Firstly, you need to decide on which wall to paint in your living room. I chose the background wall of my indoor snake plant to transform it into a focal feature. Once you zero in on the spot for the DIY geometric wall art, move out the furniture from the area to protect them against paint splashes.

Step 2: Mask the wall footer with tape

To protect the wall footer and to ensure that you have a neat finish for your triangle painting project, stick washi or masking tape over it. If you are trying a DIY painting project for the first time, it's advisable to cover the floor as well.

Step 3: Cover plug points, switches and other surfaces

If there are any other surfaces such as plug points or switches that you don't want to paint, cover them as well with washi tape, cutting as close to the border as possible with an X-Acto knife.

Step 4: Mark the size of the triangle painting

Measure and mark the size of the geometric wall painting. I measured 80 cms at the bottom of each side of the wall as I wanted both sides of the triangle to be of the same size. Apply washi tape along the marked line at the foot of the wall.

Step 5: Create the triangle shape of the DIY accent wall

You might need the help of someone for this stage as you need to paste washi tape from the edge of the bottom to the mark at the top. Ensure that the tape is stretched in a straight line. Repeat the other side, so that the washi tape creates the border for the triangle shape in the corner of the living room.

Step 6: Prepare the paint mix

Shake the can of paint, and then, open it and mix well before you start painting to ensure that the pigment is evenly distributed. Otherwise, the colour might appear patchy once it is dry.

Step 7: Fill a tray with paint

It’s best to use a paint tray for pouring your paint, but if you don’t have one, you can use a baking tray or a similar shaped one. A tip – cover the tray with aluminium foil or plastic wrap so that you won’t need to struggle with trying to wash the paint off the tray once you finish.

Step 8: Start painting your geometric wall feature

Dip a roller in the tray of paint and start filling in the area between the triangle marked with the washi tape. For the narrow sections such as the apex of the triangle, you can use a thin brush to fill in the gaps. Apply a couple of coats until you are satisfied with the effect. Try not to paint on rainy days as the wall might not absorb the paint, resulting in an uneven finish.

Step 9: Allow the paint to dry

Ideally, it would be best if you left the paint to dry overnight, before removing the washi tape and examining the result of your geometric wall painting. A tip for getting rid of the paint smell in the room – leave a window open, if possible. Alternatively, you can place a dish with baking soda near the painted wall as it will absorb the smell.

Step 10: Enjoy your new DIY accent wall

Here’s how my wall looks after the triangle painting. I chose light pink to match the grey walls. For ideas of colours and combinations or even other patterns you can use, you will find many easy paint designs for walls on Pinterest. Give this project a try, and have fun with it!
