It’s super easy and fun to make. I really trusted and let my hand do the work. I didn’t plan the shapes I just went with the flow and even though now I would have done a few things differently, I loved the shapes that came out!

This craft was inspired by my sweet friend Lauren from the thinking closet. She always inspired me to make cute and fun things. This is another one of them.

I used my favorite colors {ahem, my new favorite colors LOL}. I got obsessed with turquoise but I still have a deep love for my pink. I added a silver color and a bit of purple to make it pop.

I LOVE the result and who knew I even end up using the colors on my Theme design haha.

How to Make these cute geometric painted cork coasters

Let’s do it!

Supplies:

  • Plain cork coasters – round or square coasters work
  • Acrylic paint in different colors {and metallic paint if you want}
  • Masking tape or painters tape
  • Paint brushes
  • Water-resistant clear acrylic paint sealer spray or shellac finish & sealer

Tools:

  • Scissors.

Instructions:

Firstly make sure to clean your coasters. Free them from grease and dust.

With the masking tape, make random shapes. Cut the masking tape in different widths so it’s all uneven. I made them like this:

Next, start painting. I didn’t have turquoise color, so I made it. The picture makes it look more bluish, but believe me, it’s turquoise LOL.

I painted different spots with different sizes with each color getting this:

Now, Let it dry for a couple of hours – although these paints dry really fast, it’s even better to wait 24 hours just to be safe.

Then seal it. Spray or apply the waterproof craft sealant before removing the tape. Remember that the cork is absorbent and you wanted to leave some of that absorbent surface exposed to help soak up any liquid on a sweating glass.

Here comes the fun part. When dry, peel off the masking tape to reveal the result!

Always, always read the instructions on your can for specifics. I have found that these sealants take time to cure completely, so it’s recommended to wait at least 2 weeks to put hot drinks on the coasters to avoid the tacky sensation.

Lastly, repeat the process with all your coasters just change the pattern and create amazing designs.

That’s it!

I made all 4 of these in less than an hour and I couldn’t be happier.

Tadaaaaa!!!! LOVE it. I might do new ones but with thinner lines of masking tape so there are more painted areas. But I still love the result.

I’m planning on making some more and trying different shapes!

We can always use different materials too, like wood, and plastic. Anything can be useful with a little imagination!

Crafting Tips

– Embrace your inner doodler and let the pen lead the way. Grab a fine-tip marker or a gel pen and start doodling anything that comes to mind – squiggles, flowers, unicorns, or even aliens. It’s a guaranteed way to add whimsy to your coasters.

– Instead of a brush, you can also try using a sponge to apply your paint. This will give your coasters a fun, textured look and make them stand out.

– It’s easy to focus on the top of your coasters, but don’t forget about the sides! A pop of color or a fun pattern on the edges can really make your coasters stand out.

– Consider adding a personal message or a fun design that represents you or the person you’re giving the coasters to. It’ll make them extra special and unique!

Frequently Asked Questions

What type of cork coasters should I use for acrylic painting?

Preferably opt for thick, absorbent coasters made of natural cork. They’re perfect for soaking up those vibrant acrylic colors and ensuring a smooth painting experience.

Do I need to seal my painted cork coasters?

It’s highly recommended! Acrylic paint can be prone to scratching or fading over time, so applying a clear sealant like varnish or polyurethane will protect your masterpiece and keep it looking fresh. I recommend applying the waterproof craft sealant before removing the tape

What brushes should I use for acrylic painting on cork?

You have plenty of options! Soft-bristle brushes work well for smooth strokes, while stiffer bristles can add texture. Also, foam brushes work wonderfully. Experiment with different sizes and shapes to achieve the desired effect.

How long should I let the paint dry before applying a sealant?

Patience is key! Acrylic paint typically dries within a couple of hours, but to be safe, give it a full 24 hours to ensure it’s completely dry before applying any sealant. Good things come to those who wait!

How do I clean my painted coasters?

You can wipe them clean with a damp cloth, but avoid soaking them in water or putting them in the dishwasher.
