Finding the best pouring medium for acrylic pouring can feel like an expensive guessing game when you’re just starting out — I know because that’s exactly how it started for me.
When I was new to paint pouring, the price of pouring medium gave me a little sticker shock. I knew straight water wasn’t going to cut it on its own — I needed something that would help the paint flow without breaking it down. So, being the crafty type, I started researching how to make my own. What I landed on is still my go-to recipe today: Floetrol, Elmer’s Glue-All, and water. Simple, affordable, and it works.
That said, I’ve genuinely come to love how many good options are out there now too. Australian Floetrol and Amsterdam pouring medium are fantastic for cell effects. DecoArt and FolkArt are my picks for puddle pours and tree rings. Liquitex is what I reach for on Dutch pours. There’s a real medium out there for whatever effect you’re going for — you don’t have to stick with just one.
If you’ve ever poured two batches of paint that looked identical in the cup and watched them do completely different things on the canvas, the medium is usually why. Pouring medium isn’t just a nice-to-have — it’s the difference between a pour that flows the way you want and one that fights you the whole way.
Here’s what actually works, what each one is good for, and how to pick the right one for what you’re making.
What Does a Pouring Medium Actually Do?
A pouring medium is a liquid additive that turns thick acrylic paint into something that flows smoothly across a canvas. Without one, you’re stuck fighting paint that’s too thick to move the way fluid art needs it to.
A good medium does four things: keeps your paint flowing smoothly instead of streaking, helps it dry evenly across the canvas without cracking, keeps colors vibrant instead of dulling as they dry, and gives you the cells and lacing patterns that make a pour look intentional instead of accidental. Skip it, or use a bad one, and you’ll usually see the opposite: streaking, surface cracks, dull color, and drying that looks uneven no matter how carefully you poured.
The Most Common Pouring Mediums (and What They’re Actually Like)
Floetrol
Floetrol is the budget-friendly option most people start with — it’s a hardware store product, not an art supply, and it’s genuinely good at creating cells and lacing. The tradeoff is some batch-to-batch variability, so don’t be surprised if two bottles behave slightly differently.
Liquitex (and Other Professional Pouring Mediums)
This is the industry standard for a reason. Liquitex, Golden, and DecoArt all fall into this category — consistent coverage, colors that stay vibrant as they dry, and fewer surface cracks than the budget options. It costs more, and it tends to produce fewer large cells than Floetrol, but if you’re building pieces to sell or gift, this is the safer bet.
Glue-Based Medium (Elmer’s Glue-All)
Mixing roughly 60% glue to 40% water gives you a workable, genuinely inexpensive pouring medium — good for practice pours, kids’ projects, or just learning the ropes without spending much. My own go-to recipe builds on this: Floetrol, Glue-All, and water together, which smooths out some of that duller finish while keeping the cost down. It’s still what I reach for today. The plain glue-and-water version has real tradeoffs, though — it tends to dry duller, has a higher chance of yellowing over time, and cracks more easily than a purpose-made medium. Great for learning, not something I’d use on a piece meant to sell.
Gloss Medium
Worth knowing this one isn’t technically a pouring medium on its own — it’s something you add to boost shine on a gallery-wrap canvas or finished piece. A little goes a long way; too much and your mix gets noticeably thicker.
Quick Comparison
| Medium | Best For | Watch Out For |
|---|---|---|
| Floetrol | Cells, lacing, budget-friendly experimenting | Batch variability |
| Liquitex / Golden / DecoArt | Selling or gifting, consistent results | Higher cost, fewer large cells |
| Glue-Based (Elmer’s) | Practice pours, kids’ projects | Duller finish, yellowing, cracking |
| Gloss Medium | Extra shine on finished pieces | Thickens the mix if overused |
How to Choose the Right Medium for Your Project
| Project Type | Recommended Medium |
|---|---|
| Beginner practice tiles | Glue-based, or a small batch of professional medium |
| Gifts and keepsakes | Professional pouring medium |
| Artwork you plan to sell | High-quality professional medium only |
| Large canvases | A medium with strong leveling properties, like Liquitex |
| Extra-shiny finish | Pouring medium plus a gloss boost |
A better medium usually means fewer “mystery mistakes.” If your pours keep turning out streaky or dull for no clear reason, it’s worth asking whether the medium is the actual problem before assuming it’s your technique.
Matching Medium to Technique
Beyond budget versus professional, some mediums genuinely pair better with certain pouring techniques. If cells are the whole point, Australian Floetrol and Amsterdam pouring medium are both excellent choices. For puddle pours and tree rings, DecoArt and FolkArt tend to give the results I want. For Dutch pours specifically, Liquitex is my go-to. None of this is a hard rule — but if you’ve been using one medium for everything and getting mixed results, it might be less about your technique and more about matching the medium to what you’re actually trying to create.
Additives Worth Knowing About
Beyond the medium itself, a few additives change what your pour can do:
Silicone oil creates cells — a few drops per cup is usually plenty, and more isn’t always better.
Isopropyl alcohol creates the lacing, web-like patterns you’ll see in a lot of advanced pours.
Dish soap gives you a subtler cell effect than silicone oil, and it’s already sitting in most people’s kitchens.
A heat gun or torch (used briefly, from a safe distance) helps pop bubbles and can enhance cell formation after your pour is down.
Water thins your mix for softer blending, but use it sparingly — too much and you lose the color vibrancy the medium was giving you in the first place.
Tips for Mixing Success
A few things that make a real difference: mix your paint and medium completely so you don’t get streaking, aim for a consistency close to warm honey, keep water additions to no more than about 30% of your total mix, test your flow on the side of the cup before committing to the canvas, and write down what you used so you can repeat (or fix) it next time.
Frequently Asked Questions
What’s the difference between a pouring medium and just adding water to my paint?
Water thins paint, but it also dilutes the color and weakens the paint’s structure — that’s part of why watered-down paint tends to crack. A pouring medium thins the paint while keeping the pigment intact and the surface durable.
Can I mix different pouring mediums together?
You can, but it’s worth testing on a small batch first. Different mediums have different drying times and consistencies, and mixing them can give you unpredictable results — sometimes good, sometimes not. My own go-to recipe is actually a mix of two (Floetrol and Glue-All), so it can absolutely work when you find the right combination.
Do I need silicone oil to get cells, or will a pouring medium do that on its own?
Some mediums, like Floetrol, create cells on their own. Silicone oil gives you more control and typically bigger, more defined cells if that’s the look you’re going for.
Is a more expensive medium always the better choice?
Not always — it depends on the project. A budget medium is genuinely fine for practice and learning. For anything you plan to sell or give as a gift, the consistency and durability of a professional medium is usually worth the extra cost.
