How to do Your First Acrylic Pour on Rocks

I fell in love with rock painting through a couple of different kindness rock groups that I found online. I participated in that for about one year and then I happened to be on the internet one day when I saw a video on acrylic pouring. I was mesmerized by this technique and wondered if I could use this method on my work?  I decided that I was up for a challenge and that I would give it a try, on rocks!

Why not, I reasoned with myself and thought, what do I have to lose? So, I searched and watched any YouTube video or article I could find on acrylic pouring using other mediums; However, there really wasn’t much information available on the subject of acrylic pouring on rocks.

Eventually, after a lot of research and trial and error, I found a way to take advantage of acrylic pouring on rocks using my own style. 

I have been experimenting with acrylic pour techniques for just over two years now. I am loving every minute of it!

To prepare rocks for acrylic pour:

  • Dry brush the rocks to remove excess dirt and debris.                                     
  • Wash the rock(s) in dawn dish soap and a small amount of bleach, I use bleach to help destroy any bacteria or foreign matter on the rock.                                                                                                                
  • Rinse well, let dry on wire rack for at least 24 hours.
  • Apply two coats of Gesso for good paint adhesion. Let that dry for 24 hours. 
  • After the rocks are gesso’d and dry, it’s important to handle them with gloved hands only. This helps to prevent oil or dirt from your hands transferring to the rocks.                   




Let’s pour rocks!

First, I set up my pouring area. I like to use plastic table cloths from the dollar store, aluminum foil lids for buffet pans and pizza savers to hold my rocks for drying.

I choose the colors for the rock based on the image I am going to put on it. I will use anywhere from three to seven colors for the pour. I like to use white or pastel colors for my buffer paints (the colors that go between the different paint layers)  

Once all of this is completed, I will am ready to mix the paint.   


On a side note, to complement your Acrylic Pours, I highly recommend using a Cricut Machine (my personal favourite is the Explore Air 2 machine) to design and print yourself beautiful crafts on all sort of supports. Check it out here!  Now back to paint mixing.


Floetrol is my medium of choice. The amount needed for different paints varies from rock to rock. An easy rule of thumb, is mix the Floetrol and paint until the mixture is the thickness of heavy cream.

Double check the mix by loading a stir stick with paint then tip so the paint can “flow” off the stick. If it is the consistency of a glob the paint is too thick and if it is runny it is you will need to thicken it up by adding more paint.                                       

Some, heavy pigmented paints like artist’s grade paints will need considerably more medium. I have a mixture of 90% water and 10% Floetrol  I use to help mix the heavy bodied paints, adding a little bit of this mixture before adding Floetrol helps with blending the paint. This mix will help to prevent breaking down the polymer binders of the paint, which can cause the paint to lose its color.

When I pour, I hold the rock with one hand and pour over the entire rock.  Pouring this way gives the rock a more completed and even look. Place the rock on the upside-down pizza savers to dry for at least 24 hours or longer depending on the paint that was used in the process.     








Thanks for taking time to pour rock with me!

  1. This is so so so so good! I have an idea for a pour and your rock pouring is showing me it will be possible! So freaking pumped now. Thanks for this inspo!

    1. Cathy Llewelyn

      Thanks for commenting! Would love to see what you have been inspired to do!

  2. These are lovely and I am excited to give it a try but wondered what you do with the underside of the rock. Do you cover it with a material of some sort or do you paint that also?

    1. Cathy Llewelyn

      Hi Jen, the back of the rock is poured at the same time as the front. That process gives the rock a completely finished appearance.

  3. If you placed a canvas under your rock you might also create a regular painting with the overflow…just a thought

      Hi Marilyn, excellent suggestion. I will definitely give that a try. Thank you

    These are wonderful! Thank you for posting! Do you add a protective finish after the rocks are cured or are they good to go just as they are?

    Thanks in advance.

  5. What brand of paints do you use? There is so much paint wasted and practice may be costly. Do you have some paints mixed w water and floetrol and some paints w just floetrol? Do you use one drop at a time for the right texture?

    Looking forward to getting home from vacation & start a rock pour. I’ve been painting rocks since 2016. I also create pavers & paint them.

  7. You do realize that taking rocks from a beach is against the law? And subject to fines?
    Rocks serve a purpose – to cut down erosion. So next time you see a beach flooding…think of all the people gathering rocks for their pour.
    Come on people, use your head. There’s a reason why local governments buy and lay down beach rock,

    1. @Chris – you realize you can BUY rocks at Home Depot, Lowe’s, Walmart garden center, Michaels (for smaller quantities)?


      @ chris she doesn’t say get rocks at beach. she may not even be within a hundred miles of an ocean. rocks can be found in a few other places. I have seen them myself.

  8. I thought there was a video? I would have loved to see how you actually did it and how you avoided the “touch marks”. Thanks!

  9. Thanks, I have done some rock pouring, but didn’t do the bottoms. Where do you find the pizza savers?

  10. I have been wondering how to do this, as I have been trying (without much success) to do pain pouring on canvases. That’s so much but I can’t seem to save this. Do you have a UTUBE channel. Beautiful by the way thanks for sharing x
