How to Create a Rainbow Canvas in Acrylics with Masking Tape

Use This Simple Technique to Paint Inside the Lines

Every evening it seems these days, I’m looking forward to getting my work done then learning some more painting. I promise you — I will get back to software blogging sometime after summer 😂.

In this article, I’ll share with you how I painted a rainbow canvas in acrylics with the help of masking tape.

Materials

  • Acrylic paints (or spray paints)
  • Board (Winsor & Newton 10" x 8")
  • Masking tape
  • Palette knife
  • An old newspaper
  • Satin spray varnish (optional — for an excellent finish)

Laying the Foundations

Place the board on paper (ideally an old newspaper if you can find one) and place six marks evenly spaced marks on one side of the board and six marks on the other side.

Then, use masking tape to connect both sides, as shown below. We want to place the tape inside only the even columns 2, 4, and 6. This allows us to paint freely inside the odd columns 1,3 and 5, helping us keep the paint inside the lines.

Apply the red acrylic paint in the first column using a palette knife. Be generous with the amount of color you use to give texture and depth to your project.

Now skip a column and paint yellow in the third column.

And in the fifth column, apply the blue paint.

You now need to be patient and wait for the paint to dry.

Next, you’ll need to apply the masking tape in the odd-numbered columns and paint orange, green, and purple colors in the even-numbered columns:

Once it looks dry, carefully peel back and dispose of the masking tape.

Hopefully, you end up with something pretty like this?

After the paint dries, you can always apply more color very easily to areas where the canvas grain shows too much.
