Today I painted my first large scale acrylic pour. It got me thinking. There are plenty of people out there explaining their recipe, their brands, their procedure, but nobody really breaks down the sheer volume of paint you need for a given size painting.
I thought it’d be helpful if I did that here. This isn’t guaranteed to work for you. It’ll certainly depend on how messy you are, how much paint you waste in run off.
Today I painted a tree ring pour on a 36” x 48” canvas. For research purposes, I had looked up a video by an acrylic pour artist who titled her video with the exact dimensions I had planned to work with. I knew I’d be able to get a better gauge of how much paint to mix up based on how much they used. They did one large tree ring pour using three, what looked like, eight ounce cups. It covered the canvas pretty well except they didn’t coat the canvas with wet paint well enough to begin with. The pour didn’t flow well, developing snags and divots.
If you’re reading this nitty gritty information, you most likely know that for a tree-ring pour or flip-cup, or even a swipe, you coat the canvas with some color of wet paint, and paint into that surface. It relieves the surface tension and allows your color combination to flow and spread evenly and predictably. So, when I was all set up and ready to paint, I took the time to mix up double the amount of white, I thought I could possibly need. Well, I used every drop!!! I used 1.5 quarts of white!
So, it is a good idea, especially if you are doing a bigger piece, to have a good idea of how much paint you are going to need.
Substrate Size White Cup
8”x10” or 12”x12” 8 oz 1 oz (little medicine cup)
18”x24” or 24”x24” 16 oz 4-8 oz
24”x48” or 36”x48” 1.5 Qt 16 oz
Again, these are just suggestions. I am not a painter who produces a lot of run off, so if you do, you probably want to make even more.
As far as my recipe and brands, the details are in another post. But for quick review, I use GOLDEN Artist Colors exclusively and do not use silicone. I use GAC 800, another GOLDEN product, one of their mediums. I also add Flood brand Floetrol, an additive that adds flow and leveling to house paints. My proportions are 3x GAC 800 – 2x Floetrol – 1x Golden Acrylic Paint.
I hope this was helpful. Let me know in the comments if you have further questions or to request more info on a specific topic.
