A pouring medium for acrylic paint turns thick color into a fluid that flows across a canvas, levels smoothly and dries without the chalky weakness you get from thinning with water alone. The best pouring medium keeps colors separate long enough to form cells and lacing, dries without crazing, and gives the finish you want, whether that is wet-look gloss or a softer satin.
Pouring uses a lot of medium, so value and container size matter more here than with most art supplies. This guide ranks professional gloss media, bulk pump bottles, the popular Floetrol additive, and an inexpensive craft option, and explains which pouring styles each one suits.
Quick answer: Liquitex Professional Pouring Medium (32 oz, gloss) is the best pouring medium for acrylic paint when you want a high-gloss, wet-look finish from a professional brand; its high resin solids help pours level into even, flowing color. For volume at a lower tier, U.S. Art Supply’s 64 oz Gloss Pouring Medium and Shuttle Art’s 1,000 ml pump bottle are strong choices. Floetrol is the economical additive many pourers use for cells, best combined with an acrylic medium.

How We Chose
These picks are based on the Amazon listing details and specifications for each product as checked in October 2026, how well each medium’s finish, formulation and volume fit acrylic pouring, and how widely each is reviewed by Amazon buyers. We have not run pour tests; claims such as “prevents cracking” are the makers’ and are labeled that way.
- Formulation: acrylic polymer media first; additives second.
- Finish: gloss for depth, satin for softer pieces.
- Volume and dispensing: pumps and large bottles for regular pourers.
- Mixing guidance: clear ratios help beginners.
- Crazing and cracking: what each maker says about it.
Pouring Medium vs Floetrol vs Water
Acrylic pouring medium is binder: acrylic polymer that thins paint while adding film strength and gloss. It is the safest base for pours you plan to keep.
Floetrol is a latex paint conditioner designed for house painting. Its listing calls it a go-to additive for fluid art that creates cells and improves consistency. Many pourers mix it with paint, often together with an acrylic medium or glue-based mix, because it encourages cells and is cheap in gallon form. It is not an artist-grade medium, so use it thoughtfully on pieces you want to last.
Water thins paint but dilutes the binder. A little is fine for adjusting consistency; lots of water leads to weak, dull or cracked pours.

Popular Pouring Techniques and the Medium They Need
Dirty pour and flip cup
Layer colors in one cup, then pour or flip the cup onto the canvas. These techniques benefit from a medium that keeps colors from blending into mud, which most listings here address. Consistent viscosity across colors is the key.
Swipe
Pour colors, then drag a contrasting color across with a damp paper towel or palette knife to reveal cells. Medium that stays fluid for a little while helps.
Dutch pour
Colors are blown across the canvas with air from a straw or hair dryer on a cool setting. Thinner mixes and a smooth, leveling medium give elegant lacing.
Puddle or tree ring pour
Paint is poured in a controlled stream to make concentric rings. A medium with good leveling and high resin solids, such as Liquitex, keeps rings crisp.
A Simple Pouring Setup
Cover your table with plastic sheeting and set a large tray or box lid underneath the canvas to catch runoff. Raise the canvas on four cups so paint can drip off the edges freely. Use a spirit level or a phone level app to make sure the surface is flat; even a slight tilt sends paint drifting to one side as it dries.
Mix each color in its own cup with medium, using a craft stick, and bring them all to the same consistency. Keep gloves, paper towels and a palette knife within reach for edges and corrections. After pouring, leave the piece flat in a dust-free room, covered loosely with a box if needed, and resist the urge to move it until it is dry to the touch. Save leftover runoff paint in a cup; it can become a background color for the next pour.
Buying Guide: How to Choose a Pouring Medium for Acrylic Paint
Prefer acrylic polymer media for finished work
Polymer media add binder and help the dried pour stay strong and flexible. Additives such as Floetrol are useful but best paired with a medium.
Choose your finish
Gloss deepens color and gives a wet look. Satin is softer. You can always change the final sheen with varnish.
Match volume to how often you pour
Pouring consumes medium fast. A 16 to 32 oz bottle suits occasional pourers; half gallons and gallons suit regular pourers and teachers.
Look for clear mixing guidance
Ratios like Shuttle Art’s 1:1 make it easier to get repeatable results.
Think about dispensing
Pumps and squeeze bottles speed up mixing and reduce mess.
Consider crazing risk
Thick pours, drafts and fast drying cause crazing. Choose a medium that addresses it and dry pieces slowly on a level surface.

Common Mistakes to Avoid
- Thinning with lots of water instead of medium.
- Mixing colors to different consistencies.
- Pouring on an unlevel surface.
- Using a heat gun too close or too long, which can scorch or craze paint.
- Varnishing before thick pours have cured.
- Leaving silicone residue on the surface before varnishing.
FAQs
What is the best pouring medium for acrylic paint?
Liquitex Professional Pouring Medium is a strong choice for glossy, professional results. U.S. Art Supply and Shuttle Art offer good value in larger sizes.
Can I use Floetrol as a pouring medium?
Many pourers use Floetrol for cells, often mixed with an acrylic medium. It is a house-paint additive rather than an artist medium.
What ratio of pouring medium to paint should I use?
It depends on paint body and product. Shuttle Art suggests 1:1. Heavier paints need more medium. Aim for a consistency like warm honey.
Why are my acrylic pours cracking?
Common causes include thick layers drying too fast, too much water, drafts or heat. A good medium and slow, level drying reduce cracking.
Do I need to varnish an acrylic pour?
Gloss media dry shiny, but varnish adds UV and dust protection and evens sheen. Clean the surface first if you used silicone.
Can I use pouring medium on wood?
Yes. Many listings mention wood, canvas and other surfaces. Prime or seal raw wood first for best adhesion.
Final Recommendation
Choose Liquitex Professional Pouring Medium for glossy, professional pours. For value, U.S. Art Supply’s half gallon or Shuttle Art’s pump bottle are excellent, and Nicpro or Handy Art make sense for classes and studios. Use Floetrol for budget cells alongside a medium, and Apple Barrel for satin practice pours while you learn.
