Rock painting ideas for the Kindness Rock Project

Rock painting is big these days – and I totally get it. You’ve got one of nature’s smallest canvases upon which to decorate, and endless combinations of paint, markers, and embellishments. If you paint a rock you don’t like, you can easily move onto the next.

Not only that, but rocks are great fun for adults AND make great kids crafts. Rock crafts are easy, and there are endless ways to decorate your stone surface. Plus if you’ve seen the various designs, they’re such cute things to paint. For all these reasons, I love them!

Then we haven’t even gotten to the part where you can distribute painted rock art around your neighborhood and put a big smile on someone’s face (have you heard of the Kindness Rocks Project?)

If you haven’t heard of them, kindness rocks are a viral trend! Maybe you’ve seen painted rock art lying around in a random public location – that’s quite possibly a kindness rock.

It started with the Kindness Rocks Project and their mission of “one message at just the right moment can change someone’s entire day, outlook, life.” I happen to completely get behind this mission.

The Kindness Rock Project is the thing that got me started painting rocks in the first place – and now I’m hooked. I’ve painted so many rocks that I have a lot of ideas (and tips!) for you.

Simple Rock Painting

Before we dive into the rock painting, let me answer a few commonly asked questions for you. These are important to know before you start, and will give you a general idea of what to expect.

How do you prepare rocks for painting?

All you need is a mild soap, water, and a colander (and really the colander is even optional but just makes it easier). Place the rocks in the colander, turn the water on and rinse.

Rub each rock with a bit of mild soap to remove dirt, then rinse again. You can leave in the colander to let dry or place them out on a towel on your counter. If you’re really desperate to get started, you can even use a hair dryer.

Will acrylic paint work on rocks?

Absolutely! Acrylic paint is going to be your best friend for rock painting. You’ll want to use something that is rated for the outdoors or multi-surface.

What is the best paint to use on rocks?

Funny you should ask! My favorite paint to use for rocks is FolkArt Multisurface. Plaid also carries a FolkArt Outdoor paint and an Apple Barrel Multisurface paint that I love.

I find that the FolkArt Multisurface has my favorite colors, but all three lines are perfect. The Apple Barrel is great for kids’ rocks because it’s inexpensive yet durable.

How do you seal painted rocks?

I love this question – with Mod Podge, of course! Outdoor Mod Podge is my favorite for this purpose, and then a spray sealer. I find that extra durability of using both together makes the rocks extra tough – and the colors last a lot longer.

How to Paint Rocks

Let’s get to the instructions! First you’re going to need rock painting supplies, and I’ve listed those for you below.

Gather These Supplies

  • Rocks – the more flat and smooth, the better
  • Mod Podge Outdoor
  • FolkArt Multi-Surface Paint
  • Markers to embellish the surface of your rocks – I recommend Pebeo Vitrea markers or oil based Sharpies (you can use acrylic paint too)
  • Paintbrushes (and a detail brush for writing)
  • Brush-on or spray clear sealer

Step One: Wash all dirt off of your rocks if you found them outside. Michaels sells flat river rocks which makes it easy since flat rocks can be REALLY hard to find!

Step Two: Decide whether you are going to paint the rocks or write directly on them. If you are painting, move to step three. If you are writing directly on the rocks, prep the rocks with the brush-on or spray clear sealer.

You won’t want to use the Mod Podge Outdoor to prep because it doesn’t take markers very well. Your oil based Sharpies especially can get their tips ruined very easily without this prep step!

Step Three: Place your paint in a palette and get painting on your rocks! I found that most rocks only needed a few coats of the paint.

Painting stones in shades of blue and turquoise

Paint one side, let dry, then flip over and paint the other side. Once you are done painting, let everything dry.

Step Four: If you didn’t do the sealing from Step Two before since you were painting, now’s time. Trust me.

Adding details to a rock with a paint pen

Step Five. Embellish your rocks with sayings, designs, or whatever you like. I made those aqua dots with the end of a paintbrush!

Step Six: Once your rocks are dry, coat them with Outdoor Mod Podge! Give several coats and let dry.

Remember to be considerate when leaving your rocks places. Don’t leave them at private residences or businesses without asking, and National Parks/National Forests are off-limits due to their “Leave no Trace” policies. There are plenty of other places to leave your fabulous rocks to be found!

Hi Amy, Can I decoupage flower napkins, paper pictures such as pumpkins, spiders, etc on painted rocks then seal them?


Tuesday 3rd of October 2023

Hi Debby! Yes you can! Here's paper:

Rocks are way cooler without paint. I can't stand finding rocks that people have painted. It's like finding or installing real hardwood floors in your home and then painting over them. Why don't you get creative and carve your message/designs into the rocks then sand them to bring out their natural beauty?


Wednesday 2nd of August 2023

Hi Dustin! I see your point! Dremel it up :)

I'm a professional rock artist and admin of kindness rock groups mod podge is not a sealer it will melt off the rocks. Spray seal.

@Amy, I’ve used it as well and never had any problems. Maybe humidity affects it sometimes. I love all your works. Really is inspiring. I live at the beach. I think now that summer is upon us I’ll start leaving some painted rocks along the shell line so when kids come upon them they’ll be excited. Keep up your good work.

@Susan, professional rock artist? Wow, first time I’ve heard of that. I like learning new things!


Sunday 2nd of October 2022

Hi Susan! I've used the outdoor on many rocks and never had it melt off!


Friday 29th of July 2022

I just started rock painting. After reading several Pinterest articles & looking at you tube views I decided to use Uni Posca paint pen to write my signature on the back of my rock. I had Modge Podge dishwasher safe gloss on hand and thought it would be a good sealer, but the black ink ran immediately. Thank goodness it was easily repaired. I am glad I didn't try sealing my artwork with it. I will try the spray sealer next time. Thank you for your easy rock painting ideas!


Wednesday 31st of August 2022

Hi Ginga! That is odd. Did you use it right away or did you let the Posca paint pen dry first?


Tuesday 29th of June 2021

I would caution on using Modge Podge Outdoor. It is not waterproof! I tried this and when it rained my rocks were a mess. I just use a spray sealer.
