DIY Abstract Painting with a Putty Knife

The one rule that I love most about DIY abstract painting, especially when I teach/lead a workshop on it, is that there really aren’t a lot of rules.

It isn’t about having to draw the perfect line, or make it look exactly like a tree… It’s about painting what you feel, and what you see, and if you like it or not.  The scariest part of abstract painting is having to get over is putting that first stroke of paint on the canvas. My DIY abstract painting tutorial today is more about giving you the direction, and guideline, and how to use an abstract painting technique that involves layering paint. We are also going to have fun using an unconventional painting tool too, so pull out your drywall putty knife, and get ready to paint!

I’m using a wood framed board canvas, but this technique could apply to a regular canvas as well. For this project, you’ll need:

A large flat brush, a 3″ drywall putty knife, paper towel, canvas, palette or plastic plate

Supplies to paint DIY Abstract Art Jennifer Rizzo

DecoArt Premium Acrylic paint in Titanium White,Warm Grey, Carbon Black, Burnt Umber and Cadmium Yellow Hue,  Extreme Sheen in 24K Gold, and Creme Wax in Deep Brown ( if you are going to stain the frame.) Find supplies on this idea list here.

This project would also be a good way to use this kind of paint and if you want to add a frame in an inexpensive way to your canvas, you can see how to do that here.

Start by painting a layer of Titanium White on your canvas. This will ensure a smooth glide for your future paint layers. This is a good idea to do even if you buy a pre-gessoed canvas.

Add abstract strokes of acrylic paint as a base layer.

After your canvas is coated and dried, paint short brush strokes of black, burnt umber, gray and yellow, covering the canvas. This is probably going to look pretty bad. It’s ok, it’s just a base layer. We are going to cover most of it up, I promise, so don’t panic.

After your base layer is up, use a large brush to make  downward strokes towards the middle. Turn the canvas over when you want to do the bottom edge. You want your strokes to be slightly patchy, so the colors underneath peek through  a little.

Once you have the coverage you like with the white paint on your DIY abstract painting, next use the warm gray and your large brush to paint a line straight across the middle of the painting. Use short downward strokes, moving across the canvas horizontally.

Mix some black paint in with the Warm Gray paint, and brush on some sections of a darker gray over the lighter gray. When I painted on my gray line, I made one side  wider than the other. That was just a design choice. You can keep it the same size if you want all of the way across.

Here’s where you get to play with your drywall putty knife.

Pick up some white paint on the edge, and with a downward motion, apply it to the canvas, stopping at the gray line.

You should get a really patchy , organic kind of pattern, and that’s just what we are going for! It’s that look for incompleteness that makes this painting of this DIY abstract painting!  Flip the canvas upside down to work from the other edge.

Add a gold stripe by stippling on paint Jennifer Rizzo

Once your white is applied, take a brush and stipple some gold on over the middle of the gray, using a light, pouncing motion, moving across the canvas.

Once your stippling is done, use the putty knife again to apply the gold paint in a random way across the line, right in the middle.

It almost goes on in a blobby way, and I like that. Once you have your paint on, and you like what you see, let dry. Less is more when adding paint.

Stain your wood with a creme wax

I wanted to give the frame a natural feel, with a little color, so I used Americana Decor Creme Wax. It let the natural wood come through, and gave it a rich finish that paint wouldn’t do.

After applying it with a brush, I used a paper towel to remove the excess and let dry.

Once the painting is dry, just put a sawtooth hanger on the back to hang, and enjoy your artwork! When I staged the picture, I couldn’t decide which lamp to use, so I pulled three different lamps from around my house to see which one I liked best.

I tried a wood lamp first, but I felt it was a little tall, and I couldn’t really see the painting.

Then, I tried a slightly smaller white lamp, but it still felt tall.

I finally decided on this small black lamp from the kitchen, I felt it showed the painting off the best, and was the right scale.  I hope you enjoy diving into DIY abstract painting! Let me know if you try it, I would love to see your painting!

  1. Hmmm, wish I could see this in action; your painting tutorials really lend themselves to video… maybe a YouTube channel that you could link here? (Would that be easier to share / document? 🙂
    Must be time for you to teach another online class – just sayin’…(since you have all that extra time and all lol).

  2. Girl, this is awesome. I am better at lainting walls, than canvas, but I seriously think I could do this!! I’m going to try it, ifnits horrible, I’m paying you to do one for me

  3. Love this! Would you mind telling me what the pretty font is please? eg You should get a really patchy etc
    Many thanks
