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. 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!
