Until now, I haven’t used any silicone additives in my acrylic pour paintings, so they’ve had more of a marbled look (which I love) and only have small cells, if any. Cells are one of the trademarks of acrylic pour paintings, and they add some seriously cool texture and variation (which I also love). In the video below, I’ll give you a step-by-step tutorial on how to use silicone oil plus isopropyl alcohol to create cells in your pour paintings.
My silicone oil is a treadmill belt lubricant that’s popular for using in acrylic pouring. It’s not too expensive, and it’s 100% silicone, which is what you want for pour paintings because additional ingredients can affect your results. This could be a good thing, but it could also be a not so good thing. I’ve seen people use everything from coconut oil to WD-4o (be sure to use the silicone-based WD-40) to create cells, so you’ve got a lot of options.
I used 4 drops of silicone oil per paint color (I didn’t used silicone oil in the white paint), and at first the cells were very subtle. But after I gave the painting a few spritzes of 91% isopropyl alcohol, the cells grew almost instantly. From there, I tipped the canvas panel around a little bit more to make the cells a bit larger, and the tilting also caused the cells to reshape themselves into more organic shapes, which I loved.
I’m really happy with this first attempt at creating cells, and I have so many more things that I want to try, like changing the amount of silicone oil that I use, adding the oil to all of the paints, seeing what happens if I don’t spray the painting with alcohol, etc. Acrylic pouring really does offer endless possibilities, and it’s always exciting to see how the next painting will flow!

Supplies Used in This Project
The following supply list contains affiliate links. I make a small commission if you purchase through these links, and I really appreciate it if you do!
Husky Plastic Sheeting (or a large garbage bag / old newspapers / a bunch of plastic grocery bags / a painter’s dropcloth)
Foil Cookie Tray (to catch most of the excess paint as it runs off the edges of the painting – I purchased a set of 2 for $1.00 at the dollar store)
Vinyl Gloves (if you don’t want to be cleaning acrylic paint from under your fingernails for days, then use gloves – I buy mine by the box at Walmart in the cleaning supplies aisle)
Acrylic Craft Paints (in the video, I used Martha Stewart Wedding Cake & Beach Glass and Ceramcoat Black craft paints)
Pouring Medium (I make mine with a 1:1 ratio of Elmer’s Glue All and water)
Squeeze Bottle (I put the glue and water into this and shake it up until they’re well mixed. The squeeze bottles are a really easy way to dispense your pouring medium, and you can just put the cap back on when you’re not using so it doesn’t dry out)
Food Service Portion Cups (to hold the paint / pouring medium mixture – you can use any small plastic cups for this, or you can save yogurt containers or even plastic cat food containers and use those)
Wood Craft Sticks (to stir the paint / pouring medium mixture – I picked up a package of 100 for $1.00 at the dollar store, and once the paint is completely dry on them, you can reuse them)
Art Alternatives 8×10 Canvas Panels (if you want to hang your paintings on the wall, you should use a regular canvas, but I like these panels and buy them by the dozen from Amazon)
Plastic Shot Glasses (to raise the canvas off of the work surface so the paint can flow off the edges after you pour – I bought a package of 24 plastic shot glasses for $1.00 at the dollar store, but you can use food service containers, plastic yogurt containers, cat food containers, or even a small box under the canvas)
91% Isopropyl Rubbing Alcohol in a spritzer bottle to pop bubbles in the paint. You can spray this into the paint cups before pouring, spritz it onto the canvas after pouring, or both. Alcohol also helps to open up the cells in paintings when you’re using silicone oil.
Spot On 100% Silicone Treadmill Belt Lubricant to create cells in acrylic pour paintings. Combine with Isopropyl Alcohol for more pronounced cells.
Happy pouring!
Hello!
I am always looking forward to the mail magazine.
VOL.27 // MAY 18, 2018 and after The mail magazine has not arrived, but has not been issued and transmitted?
Hi, Yukari, and thank you! I’ve actually been having some health issues over the past few months and haven’t been able to send out The Yay List newsletter, but I’m hoping to be able to start sending it out again soon. I appreciate you checking in about it.
Comment: muito bonito seu trabalho
Thank you for answering my alcohol questions. I can’t wait to get home to pour.
Happy pouring, Jennifer!
Curious question, I use a different type of silicone but want to try using alcohol as well, do you think that will affect its results? I use moneysworth best quality liquid silicone
Silicone is good for cells but if you want to top coat with epoxy there is a problem. Epoxy won’t stick to silicone. If you wanted more cells you should have torched before the alcohol. Torching after will set your work on fire. BE CAREFUL !!! 🙂🙂🙂🙂
I received paint that says ready to pour. Does that mean I have to add medium to it if they sent me a bottle of that and a bottle of silica? I just don’t understand what to do with that
Great post – thanks for sharing these tips!
Do the alcohol have to be 91%, too made the cells?
It seems most of the YouTube videos on Pour Painting the artist floods the canvass with a white medium before the colors are added, but I am not clear on exactly what that is. I think I’ve heard the term ‘PILLOW’, and some product from Sherman Williams mentioned. Can you tell me what that might be?
Do your panels ever get warped or do they stay flat or do you prep them first
Question….do you add the alcohol to just acrylic paint? Or do you mix paint with pouring medium and then add alcohol? So add to just the paint, or paint and medium?
For whatever reason, when I add the isopropyl alcohol to my paint mixtures, it ends up getting thicker and gooey.
Loved the simple DIY pouring medium tip. Have that around the house already. I want to try a pour. I wont use silicone on my first try. But would you still recommend 91% ISO spray to remove bubbles?
I’ve researched and found that if you spray a paper towel with regular window cleaner(non ammonia) and wipe the painting (once dried for several days, it removes the silicone which rose to the surface. I got my cleaner from Walmart.
I set away for acrylic pore pants. It says it’s ready to pour so I don’t have to add medium or silicone to it. And is that correct? Why would they send me a bottle of the medium in a bottle of the silicone don’t understand what to do with it
