How do you Paint a Geometric Pattern on a Wall?

Geometric wall painting adds depth and texture to any space and not difficult to paint. All you need is some props, some fantasy, lots of time, and some patience. Let’s look at the steps of painting a geometric pattern on a wall to make your boy’s room stylish and vibrant. Watch this video to get general idea of how geometric pattern is created on the wall.

What you will need

  • Strong sticky paint tape
  • Scissors
  • Paintbrush
  • Paint dish
  • Paint roller
  • Sharpie Painter Pen
  • Needed Paint
  • Pencil for pattern drawing
  • Gloves and mask for your protection

1. Apply a Base Color

The base color will allow you to create a stripe and separate two colors in your geometric design. More often base color is white, but you can go with any light shade of grey. You can also completely ignore base color if you want two colors of geometric design to touch each other. If you choose to apply a base color, which I think looks way pretty, make sure it is completely dry before moving on to the next step.

2. Draw a Sketch on the Wall

Before you start sketching your idea on the wall, you need to transfer your ideas on paper. Once you are settled on a geometric design for the wall, make special stencils on the wall or start taping the wall in desired shapes.

3. Protect Floor

Cover the floor with a paint protection cover or clear plastic cover as a floor barrier. This will protect against paint spills and scratches.

4. Paint your Geometric Design

With the tape firmly in place, start painting your shapes. To avoid mistakes in applying paint, color code each shape before you start painting. If you want your base color to show up once you take the tape off, you can paint all of your shapes at the same time. But if you want two shapes to meet, you need to allow each shape to dry completely and move the tape to the next shape before painting the next design.

5. Apply second Coat

To make the drawing more clear, apply a second coat. Once the paint dries carefully remove the tap and complete the unfinished line with a small brush.

Now that you have general ideas of how geometric wall painting is done, let’s look at some of the trendy geometric design to paint the wall of your boy’s room.

  1. Indeed gone are the days when boys do not care about the colors on the walls in their rooms. Now they want something that is trendy or reflects their best character or something full of life, passion, energy depending on their interest and. Personally I’m still particularly about the paintings on my wall and that why I’ll always go with the Scandinavian style Mountain Effect or the Geometric Square Wall.

    1. Thank you for the comment! I agree, my 8 years old was asking for it for a long time and finally we were able to do that last year when we were stuck at home due to pandemic. But it was fun painting wall in his room with geometric pattern. We went with blue and grey random triangles.
