Why Plaster Art Canvas Projects Are So Popular
Plaster art canvas projects are having a real moment right now — and it’s not just a passing trend. From Instagram reels to Pinterest boards, these textured beauties are popping up everywhere. And honestly? I totally get the hype.
Plaster art manages to hit that sweet spot between minimalism and luxury. It looks high-end and custom, but the actual process is approachable and even relaxing. Unlike some DIYs that leave you frustrated (or with a “Pinterest fail” meme moment), this one feels almost therapeutic.
And the best part? The end result always looks good. Even if your strokes aren’t perfect or your canvas isn’t flawless, the texture has this way of hiding imperfections and turning them into character.

How I Stumbled Into Plaster Art (and Fell in Love With It)
I’ll be honest: I’m not usually the type to do a ton of research before starting a DIY project. I’m more of a “see it on Instagram, get inspired, and figure it out along the way” kind of person. Which, let’s be real, means not all of my DIYs turn out the way I imagine.
But plaster art? This one was pure chef’s kiss.
It started when I came across a reel of someone spreading plaster across a canvas with a putty knife. Something about the motion looked so soothing, and the finished piece looked like it belonged in a gallery. I thought: Okay, I have to try this.
We didn’t even know where we’d hang the finished canvases, but I didn’t care. I just knew I wanted to try. So off we went to Habitat for Humanity to hunt for materials. Habitat is always my go-to for renovation supplies and DIY treasures, and this time it didn’t disappoint — we scored two massive canvases in frames for just $25. Honestly, they were hideous in their original state, but I could see the potential.
And that’s when the fun began.
What You Need to Create DIY Plaster Artwork
One of the things I love about this project is how budget-friendly it is. You don’t need fancy art supplies. In fact, most of what you need can be found at the hardware store or second-hand.
Here’s what we used:
Frames/canvas (thrifted from Habitat for $25)
Sandpaper
Spray paint (we went with gold for the frames)
Optional: white paint to base coat the canvas
Plaster/drywall mud (aka joint compound)
Putty knives in different sizes
Optional: grooved tools for patterns
Optional: cardboard, a tarp or table covering if your DIYing inside
Spray sealant
Since this wasn’t our first reno project, we already had most of these on hand. The only things we actually had to buy were spray paint (we’d just run out) and a pack of putty knives in different sizes.
Pro Tip: Thrift stores are your best friend for this kind of project. Big canvases at art stores can run you $60+ each, but second-hand you’ll often find them for a fraction of the price. Plus, the old frames add character.
Step-by-Step Guide to Making Your Own Plaster Art Canvas
This is a DIY project you could definitely complete in a day, we spread ours out over 2 days only because it was the holidays and we were busy with family events. Here's what we did.
Step 1: Prepping the Frame and Canvas
We started by separating the canvases from their frames. Gray (my partner in crime for projects like this) gave the frames a quick sand before spray-painting them gold. I love how metallic frames instantly elevate the look of art pieces — they just scream expensive.
Meanwhile, I gave the canvases a quick coat of white paint. Honestly, you could probably skip this step if you’re starting with a blank canvas, but since ours already had colour and texture on them, I wanted a clean slate.
Step 2: The First Plaster Layer
I’ll admit: I was nervous before I started applying the plaster. My inner perfectionist was whispering: What if it looks terrible? But plaster art is surprisingly forgiving. You have so much time before it sets, so if you mess up, you just scrape it off and start again.
I started by spreading a thin coat over the entire canvas, just to get everything covered. Since the canvases were old and a bit saggy in spots, the plaster didn’t go on perfectly even. But that’s where the different putty knives came in handy. Smaller knives helped me work around the quirks of the canvas.
Step 3: Playing With Texture
This was the fun part. I didn’t really have a design in mind, so I took a quick break to scroll Etsy for inspiration. (Side note: some of those plaster art canvases are so pricey — I felt extra motivated to DIY at that point.)
In the end, Gray and I decided to experiment. He tried slapping the plaster with a knife to create raised textures, while I did sweeping motions for a limewash effect. We even pulled out a grooved tool to add some lines. The result was perfectly imperfect — the two canvases didn’t match exactly, but the textures tied them together.
Step 4: Drying & Sealing
We left the canvases to dry for about 36 hours. Ideally, you’d leave them flat for the full 48, but we had family coming over for Christmas dinner and needed our island back, so they spent some time lying on our bed before standing upright.
Once fully dry, Gray sealed everything with a clear coat to prevent future cracks. Even though a couple of small cracks did appear, they actually add to the charm.
My Trial-and-Error Process (and Why You Shouldn’t Fear Mistakes)
Here’s the thing about plaster art: it’s not about perfection. The beauty comes from the layers, the depth, and the little quirks. I definitely had moments where my design didn’t look the way I pictured it. But instead of scrapping the whole project, I just added more plaster, smoothed things out, or changed direction.
One of my favourite parts of DIY is the freedom to experiment without pressure. Unlike painting a wall (where one mistake means hours of fixing), plaster art invites you to play. It’s forgiving, flexible, and honestly fun.
Tips for Getting the Perfect Texture on Your Plaster Art
Don’t overthink it. Go with the flow and let your hand movements create the design.
Use a mix of tools. Big knives for sweeping strokes, small ones for details.
Layer it on thicker than you think — about ¼ inch works best.
If you don’t like it, scrape it off or add more plaster. Easy fix!
Common Mistakes to Avoid with Drywall Art
There really isn't much that can go wrong with DIY plaster art (which is why it's a great beginner project), but there are a few things that will extend the life of your artwork and they are
Moving your canvas upright too soon. (Patience is key!)
Applying plaster too thin or too thick.
Skipping the sealant.
Cost Breakdown: How Affordable Is DIY Plaster Artwork?
Of all of the DIY projects we've done this is definitely one of the more affordable ones because you really don't need to buy special tools, most of the tools and materials required are things that you likely have around your house already, especially if this isn't your first DIY project.
This is a breakdown of what we spent:
Item | Cost |
Frames (Habitat) | $25 |
Sandpaper | $2 |
Spray paint | $23 |
Plaster compound | $15 |
Varnish spray | $21 |
Putty knives | $5 |
Total: $70
But here’s the kicker: we had tons of materials leftover, so future projects will cost way less. And honestly, the finished canvases look like they belong in a designer catalog.
Styling Ideas for Your Finished Plaster Art Canvas
When we hung our canvases in the master bedroom, I couldn’t stop smiling. They totally transformed the space.
Some styling ideas for your own pieces:
Place them side by side above a bed or sofa.
Use smaller canvases to create a gallery wall.
Add subtle paint accents for a pop of colour.
Lean them against the wall on a console table for a casual vibe.
FAQs About Plaster Art Canvas Projects
Is plaster art durable?
Yes! Once sealed, your plaster art canvas will hold up well and resist cracking.
Can I add colour to my plaster artwork?
Absolutely. You can mix in paint with the plaster before applying or paint over the plaster once dry.
Do I need special tools for texture?
Nope. Putty knives work great. Grooved tools can add variety, but they’re optional. You could even use items from around your house like butter knives, sponges, paint brushes, etc.
How long does DIY plaster artwork take?
Hands-on time is just a couple of hours, but you’ll need 24–48 hours for drying. I also spent about an hour (once I started) looking up photos for inspiration on different textures and patterns to try on the canvas. This is a project you could start and finish in a day.
Where can I find affordable canvases?
Thrift stores, Habitat for Humanity, Facebook Marketplace and even old artwork you no longer want are perfect for this project. Occassionally, craft stores will put their blank canvases on sale as well which make them more addorable.
Final Thoughts on Plaster Art Canvas
This plaster art canvas project was one of my favorite DIYs yet. It was affordable, relaxing, and left me with pieces that genuinely feel like high-end artwork.
Would I do it again? In a heartbeat. In fact, I’m already dreaming up my next round — maybe adding some paint accents or experimenting with different shapes and textures.
If you’ve been on the fence about trying plaster art, let this be your sign: grab a canvas, some drywall mud, and a putty knife. I promise, you’ll be amazed at what you create.
