If you have ever opened a bottle of Liquitex and thought it looked like cement, or watched your color dull to chalk after drying, you already know that picking the best mediums for acrylic pouring is the single biggest decision behind every pour. I have spent the last three months running dirty pours, Dutch pours, and tree rings through 10 different mediums to find out which ones actually deliver what the label promises.
A pouring medium is a liquid additive mixed with acrylic paint to improve flow, prevent cracking, and keep colors vibrant without weakening the binder the way plain water does. In this guide, I will walk you through the top 10 mediums I tested, the ratios that worked for each paint type, and the mistakes I made so you do not have to repeat them. Whether you are pouring your first canvas this weekend or selling finished pieces and need archival quality, this list has something for you.
By the end, you will know which medium is right for your technique, your budget, and your finish goals. Let us get into it.

1. Flood Floetrol 1 Gallon – The Versatile Industry Workhorse
Flood Floetrol 1 Gal Latex Paint Additive & Conditioner
1 gallon jug
Improves paint flow
Soap & water cleanup
Cell creator with silicone
Pros
- Improves paint flow and self-leveling on walls and canvas
- Eliminates brush and roller marks for clean pours
- Reduces tip clogging in sprayers
- Functions as a paint pouring medium for fluid art
- Easy soap and water cleanup
Cons
- May require experimentation with ratios for spray applications
- Gallon size is more than casual users need
Flood Floetrol is the medium I keep coming back to, and not just because it is the highest rated pouring additive in this entire lineup at over 21,000 reviews. I ran Floetrol through a Dutch pour, a dirty pour, and a tree ring on three different canvases, and the consistency held every single time. The paint glides across the canvas instead of fighting you, and colors stay true without going chalky.
What I appreciate most is the flexibility. You can use it for house painting one weekend and fluid art the next, and it does both jobs well. Reviewers on Reddit consistently call it the go-to for cell effects when paired with a few drops of treadmill silicone oil. The 128 fluid ounce jug also means I am not running to the store mid-project.
The gallon size is the trade-off, though. If you are a casual pourer doing one canvas a month, this is overkill. But for anyone running a small studio, teaching a class, or pouring larger pieces, the volume is a real advantage. I found that 1 part Floetrol to 1 part paint gave me the best flow for puddle pours without losing pigment strength.
How Floetrol performs on different surfaces
I tested Floetrol on stretched canvas, wood panels, and ceramic tiles. On canvas and wood, the self-leveling was excellent with no bare spots. On ceramic tile, the paint needed slightly more medium to flow correctly because the sealed surface resisted absorption. For outdoor projects, reviewers note that adding a top coat is essential since Floetrol alone is not waterproof.
When Floetrol is not the right pick
Skip Floetrol if you want a true gloss finish out of the bottle. It dries mostly clear but not mirror-shiny, and adding silicone for cells can leave a slightly waxy feel. For pure gallery-style gloss, look at Liquitex or Pebeo instead.
2. Liquitex Professional Pouring Medium – The Gold Standard
Liquitex Professional Effects Medium, 32-oz, Gloss Pouring Medium
32oz bottle
High resin solids
Gloss finish
Self-leveling
Pros
- High resin solids produce even puddles and flowing sheets
- Dries to a high gloss wet-look finish without cracking
- Does not reduce paint opacity or pigment vibrancy
- Self-leveling for clean finished pours
- Lowers viscosity of heavier body paints
Cons
- Does not produce cells without added silicone or oil
- Can be messy and difficult to clean off skin
- Drying time is long at around 72 hours
Liquitex Pouring Medium is what every other medium gets compared to, and for good reason. I poured three canvases using Liquitex mixed with Soft Body acrylic at the brand’s recommended ratio of about 1 part paint to 5 parts medium, and the result was the cleanest, glossiest pour I have ever pulled off. No chalkiness, no color shift, just a wet-look finish that looks gallery-ready the moment it dries.
The medium is thicker than most out of the bottle, which is the most common Reddit complaint. Beginners often use it straight and end up with cement. The trick is to thin slightly with water (no more than 10 to 15 percent) or mix with a thinner medium like Floetrol. Once you dial in the ratio, the flow is exceptional.
I noticed the 72-hour cure time is real. If you try to varnish or move the canvas too early, fingerprints and dents appear. Plan your pours around a 3-day window before sealing.
Liquitex vs Floetrol for cells
Liquitex will not give you natural cells. You will need to add silicone oil, alcohol ink, or torch the surface with a heat gun to create that marbled effect. If you want cells without additives, Floetrol or DecoArt are better starting points. Liquitex is the choice when the finish quality matters more than the cell pattern.
Best paint pairing for Liquitex
Soft Body acrylics work beautifully with Liquitex because the viscosities match. Heavy Body paint works too but requires more medium to flow. Craft acrylics like Apple Barrel can be used, but expect slightly less vibrancy because of the lower pigment load in student-grade paints.
3. U.S. Art Supply Gloss Pouring Medium – Best Bang for Buck
U.S. Art Supply Professional Gloss Pouring Medium 32oz (Quart)
32oz quart bottle
Non-toxic ASTM D4236
Gloss finish
Pre-mixed
Pros
- Creates a glossy high-shine finish on poured pieces
- Improves flow and prevents cracking or fading of colors
- Non-toxic and ASTM D4236 compliant
- Does not alter paint color or adhesion
- Excellent value for large 32 oz bottle
Cons
- Some users report gloss fades as the paint dries
- Flow can be thicker than expected without additional mixing
U.S. Art Supply’s Pouring Masters formula surprised me. For a quart bottle, the flow rivals Liquitex at a noticeably lower price point, and it carries the ASTM D4236 non-toxic certification that matters if kids or pets are around. I ran a side-by-side dirty pour with Liquitex, and honestly the difference in finish was hard to spot at normal viewing distance.
The brand claims the gloss does not fade as it dries, which I tested over a 10-day window. There was a slight dulling after day 7 on one piece, but adding a thin gloss topcoat fixed it. For most hobbyists, that trade-off is worth the savings.
The 32-ounce bottle is the sweet spot for solo artists. It is large enough to finish multiple canvases but small enough to store without taking over a shelf.
Mixing ratios I used
I found that 2 parts medium to 1 part paint gave a beautiful Dutch pour with good flow and color retention. For tree rings, dropping to 1:1 produced cleaner rings without flooding. The medium mixes smoothly with both heavy body and fluid acrylics.
Who should skip this one
If you need true archival quality for high-end sales or commission work, Liquitex or Pebeo are safer bets. U.S. Art Supply is built for hobby and learning pours, and it does that job at an excellent price.
4. Mont Marte Premium Acrylic Flow Medium – Starter Friendly
MONT MARTE Premium Acrylic Flow Medium 250ml
250ml bottle
2 hour cure
Non-toxic
Gloss finish
Pros
- Thins and dilutes acrylic paints without affecting color intensity
- Improves flow for fluid art and pouring
- Increases translucency while keeping vibrancy
- Versatile across interior and exterior applications
- Quick 2-hour full cure time
Cons
- Smaller 250 ml size may run out quickly for prolific users
- Not waterproof once dry
Mont Marte’s Premium Acrylic Flow Medium is the bottle I would hand to a beginner. The viscosity is forgiving, the 2-hour full cure means you can finish a pour in an afternoon, and the non-toxic formula is safe for classrooms. I gave a bottle to my niece for her first pour, and the result looked better than my third attempt.
The medium thins paint without the chalky dulling that some cheaper mediums cause. I tested it with Apple Barrel craft paint, and the color stayed punchy. The 2-hour cure time is genuinely fast, which makes it ideal for kids’ projects or anyone impatient.
The downside is the 250ml size. Anyone doing more than a few small canvases a month will burn through it. I went through nearly a full bottle on a single 16×20 inch canvas with a Dutch pour.
Best beginner ratios with Mont Marte
Start at 3 parts medium to 1 part paint for your first few pours. If the paint still looks thick, add a teaspoon of water at a time until it drips like warm honey. Mont Marte accepts a bit more water than premium mediums without breaking down.
Limitations to know
The cured pour is not waterproof, so outdoor pieces need a protective top coat. The 250ml size also means you will pay more per fluid ounce than the quart options, but the trade-off is a smaller bottle that does not go bad before you finish it.
5. Owatrol Easy Flow – Dual-Purpose Conditioner
OWATROL Easy Flow Paint, Water-Based Acrylic Paint Conditioner, 34 Oz
34oz (1L) can
Water-based
Gloss finish
Multi-surface
Pros
- Eliminates brush and roller marks for a clean finish
- Versatile for both house painting and acrylic pouring art
- Improves flow and prevents crazing in pours
- Creates flexible water-resistant masterpieces when dry
- Reduces wear and clogging in paint sprayers
Cons
- May require experimentation to find the right ratio
Owatrol Easy Flow is the medium I recommend to anyone who also paints walls, fences, or trim. It is genuinely a dual-use product: stretch your latex paint on the house, then use the same can for your next pour. I tested it on a 12×12 canvas with a tree ring pour, and the flexibility of the dried film was noticeably better than Floetrol alone.
The water-resistant finish is the standout feature. Most pouring mediums stay slightly soft or need a top coat for outdoor work, but Owatrol dries to a flexible film that handles light moisture without clouding. That makes it a smart pick for garden signs or covered patio pieces.
Mixing sweet spot
I had to run three test pours to dial in the right ratio. At 1:1 paint to medium, the flow was too thick. At 2:1 medium to paint, the cells vanished but coverage was perfect. Final sweet spot was 1.5 parts medium to 1 part paint for tree rings and 2:1 for Dutch pours.
When to pick Owatrol over Floetrol
Pick Owatrol if you want one medium that handles both wall paint and canvas pours. Pick Floetrol if your pour work is heavier than your house painting. The performance is close, but the versatility leans in Owatrol’s favor for the dual-use crowd.
6. Apple Barrel Pouring Medium – Affordable Satin Look
Apple Barrel Pouring Medium, 44840E Acrylic, 16 oz, 16 Fl Oz
16oz bottle
Satin finish
Non-toxic
Multi-surface
Pros
- Affordable entry-level pouring medium
- Easy soap and water cleanup
- Dries to a subtle satin finish suitable for various surfaces
- Works with multiple pouring techniques including dirty pours
- Non-toxic formula
Cons
- Satin finish may not appeal to those wanting a high-gloss look
- Not waterproof once dry
Apple Barrel Pouring Medium is the budget pick I keep recommending to first-timers. The satin finish is a refreshing change from the high-gloss look everyone defaults to, and the 16-ounce bottle is a sensible size for someone still figuring out ratios. I paired it with Apple Barrel matte craft paint, and the result looked intentional rather than cheap.
Cleanup is genuinely easy. Soap and water, no harsh solvents, no stained hands. That alone makes it worth keeping on the shelf.
The finish is the trade-off. If you love that wet-look high gloss, satin will disappoint. If you prefer a softer, gallery-style matte-sheen, satin is perfect.
Best techniques for Apple Barrel medium
Dirty pours and flip cups shine with this medium. The viscosity holds color boundaries longer than gloss mediums, so you get cleaner separation in cup pours. Dutch pours work but require more blowing since the satin finish does not flow as freely as gloss.
Color combinations to try
Pairing Apple Barrel’s plum, turquoise, and mustard yellow with this medium produces a vintage-feel satin pour that photographs beautifully. The satin finish cuts down on glare, which makes it ideal for pieces that will be photographed or hung in bright rooms.
7. Artecho Pouring Effects Medium – Beginner Safe
Artecho Pouring Effects Medium 8oz / 236ml
8oz bottle
Translucent visual bottle
Non-toxic EN 71-3
Gloss
Pros
- Translucent visual bottle lets users see remaining medium
- Reduces viscosity and enhances paint flow
- Can double as a protective glossy finish
- Non-toxic and conforms to ASTM D-4236 and EN 71-3
- Suitable for beginners and professionals
Cons
- Smaller 8 oz size may not suit large projects
- Not waterproof once cured
Artecho’s Pouring Effects Medium is the small bottle with the thoughtful design. The translucent bottle lets you see exactly how much medium is left, which sounds minor until you have grabbed for what you thought was a full bottle only to find half an ounce inside. Beyond the clever packaging, the medium itself flows smoothly and doubles as a glossy topcoat once your pour has cured.
The EN 71-3 certification is the European toy safety standard, which makes this one of the safest picks for kids’ art projects. I felt comfortable letting my 9-year-old niece use it without worrying about skin contact.
When 8 ounces is the right size
If you pour small canvases (8×8 or 11×14), experiment with new color combinations, or run kids’ art sessions, 8 ounces is plenty. For larger work or studio production, step up to a quart or gallon option.
Doubling as a topcoat
After your pour has fully dried (give it 48 hours), brush a thin layer of Artecho medium over the surface for a glossy protective coat. It is not as durable as a dedicated varnish, but it does extend the life of the pour without buying another product.
8. Nicpro Pouring Medium – Built-In Pump for Big Studios
Nicpro Pouring Medium for Acrylic Paint 69oz/2040ml, Acrylic Paint Thinner
69oz (2040ml) jug
Built-in pump
Non-toxic
Multi-surface
Pros
- Jumbo 69 oz bottle with built-in pump reduces refills and mess
- Anti-fade and crack-resistant formula
- Translucent visual bottle for monitoring supply
- Non-toxic and ASTM D4236 and EN71 compliant
- Works on multiple surfaces including canvas stone wood leather and metal
Cons
- Some users report a strong odor
- Larger bottle may be excessive for solo hobbyists
Nicpro’s 69-ounce jug with built-in pump is the answer for anyone running a classroom, workshop, or production studio. The pump dispenses medium cleanly without dripping, which sounds like a small thing until you have spilled Floetrol across a studio table at 11 PM. I used it across a 4-canvas session without refilling once.
The anti-fade formula held up well in my outdoor test. I left one finished pour on a covered porch for 6 weeks, and the color stayed close to the indoor reference piece.
Why the pump matters
Pouring medium is thin and prone to spilling. The pump lets you dispense exactly 1 ounce, 2 ounces, or whatever you need without pouring from a heavy jug. For classroom teachers especially, this cuts down on waste and cleanup time dramatically.
Odor consideration
A small number of reviewers noted a noticeable smell when first opening the jug. In my testing, the odor faded within an hour of opening and was undetectable once mixed with paint. If you are sensitive to smells, decant into a smaller bottle and let it breathe before use.
9. Pebeo Pouring Medium Studio Acrylic – Premium Clarity
Pebeo Pouring Medium Studio Acrylic, 500ml, Transparent
500ml bottle
Non-yellowing
Gloss finish
Transparent
Pros
- Transparent and non-yellowing formula
- Does not interfere with paint color
- Can double as a top coat when used alone
- Gloss finish suitable for fluid art
- Water-based acrylic for easier cleanup
Cons
- Long full cure time of about 8 days
Pebeo’s Studio Acrylic Pouring Medium is the premium choice when color clarity matters most. The transparent, non-yellowing formula preserves paint color exactly as mixed, with no shift from wet to dry. I tested it with a high-chroma magenta, and the dried pour matched the wet pour within a hair’s breadth. That kind of fidelity is rare in mid-tier mediums.
It also works as a topcoat, which is a nice bonus for artists who want one product for both purposes. I brushed it over a fully cured pour and got an even glossy finish without streaks.
The 8-day cure is real
Pebeo officially lists 8 days for full cure. In practice, I found the surface dry to the touch at 48 hours but still slightly soft until day 6. If you plan to varnish, frame, or ship a piece, give it the full 8 days to harden completely.
Best pairing with Pebeo
Pebeo’s own Studio Acrylic paints are designed to pair with this medium, but I had good results with Golden Fluid acrylics and Liquitex Soft Body. Craft acrylics worked but needed slightly more medium to flow correctly.
10. DecoArt Pouring Medium – Cell and Crack Resistant
DecoArt Pouring Medium, 64 Fl Oz (Pack of 1)
64oz can
Cell effect creator
Crack reducer
Made in USA
Pros
- Creates impressive cell effects in acrylic pours
- Flexible film prevents cracking and crazing
- Non-yellowing and water-based
- Made in the USA
- Good value in the large 64 oz size
Cons
- Long drying time around 30 hours
- Some users find it harder to mix to ideal consistency
DecoArt Pouring Medium is the cell-effect specialist in this lineup. Reviewers on Reddit consistently call out DecoArt for producing the cleanest natural cells without silicone additives, and my testing confirmed it. I ran a Dutch pour with three colors, and DecoArt gave me more visible cells than Floetrol or Liquitex at the same ratio.
The flexible film is the other standout. I left a finished piece in my garage through a 90-degree day, and the surface did not craze or crack. DecoArt’s crack-reducer formulation genuinely works.
The 30-hour dry time is slower than most, but the matte finish it produces has its own appeal for artists who prefer a less shiny look.
DecoArt mixing tips
The medium is thicker than expected out of the can, so beginners often struggle to hit the right consistency. Add a small amount of water (no more than 10 percent) and stir gently to avoid introducing bubbles. The consistency should coat the back of a spoon without dripping immediately.
Best pour styles for DecoArt
Puddle pours and tree rings are where DecoArt shines. The cells form naturally as the colors layer, and the matte finish makes the cell patterns stand out rather than getting lost in gloss reflections. Dutch pours also work, but expect to blow harder since the thicker medium resists airflow.
How to Choose the Best Medium for Acrylic Pouring?
Choosing the best mediums for acrylic pouring comes down to three things: your technique, your paint grade, and the finish you want. Before you buy, think about what you actually want to pour, not what looks good on a label.
What is a pouring medium and why use one
A pouring medium is a liquid additive you mix with acrylic paint to improve flow, slow drying, and create a flexible cured film that resists cracking. Without it, acrylic paint is too thick to pour evenly, and adding water alone dilutes the pigment and weakens the binder. That is why bare-water pours crack, dull, and flake within days.
Pouring medium vs water: why water alone fails
Water is tempting because it is free and you already have it on your brush. The problem is that water does not contain the acrylic polymer needed to bind pigment to canvas. Once the water evaporates, the paint film has nothing holding it together. Adding more than 30 percent water to any acrylic mixture is the most common mistake beginners make, and it shows up as cracking, peeling, and chalky colors within a week. A proper pouring medium replaces water while keeping the binder intact.
Match medium to pour technique
Different pour techniques need different flow rates. Dutch pours need a medium that flows freely under air pressure, so Liquitex, Floetrol, or U.S. Art Supply work well. Puddle pours and tree rings benefit from a slightly thicker medium that holds color boundaries, which is where DecoArt and Apple Barrel shine. Dirty pours and flip cups are forgiving with most mediums. Bloom and swipe techniques prefer gloss mediums that release cleanly under a torch or heat gun.
Mixing ratios by paint type
Heavy Body acrylics need more medium than Soft Body or Fluid acrylics because of their thicker consistency. A good starting ratio is 2 parts medium to 1 part Heavy Body paint, 1.5 parts medium to 1 part Soft Body, and 1:1 for Fluid acrylics. Craft acrylics like Apple Barrel or FolkArt typically need 2:1 medium to paint. Always add water last, in small amounts, and never exceed 30 percent water in the total mixture.
Common mistakes and how to fix them
The most common mistake is adding too much water, which causes cracking and dull colors. The second is skipping the torch or heat gun pass, which leaves bubbles trapped under the surface. The third is moving or tilting the canvas before the pour has set, which causes color muddying. The fourth is using cheap craft paint straight from the bottle without enough medium, which produces chalky, streaky pours. Fix any of these by adjusting ratios, torching gently after pouring, leaving the canvas flat for 24 hours, and always using enough medium to keep pigment strength intact.
Cost per fluid ounce: getting the best value
Floetrol is the cheapest per fluid ounce of any premium medium in this test, which is one reason it earned the Editor’s Choice slot. Pebeo and Liquitex sit at the premium end with higher per-ounce cost but better archival quality. For beginners still learning ratios, Apple Barrel and Mont Marte offer small bottles at lower total cost so you can experiment without wasting money. For studios and classrooms, Nicpro and DecoArt bulk sizes bring the per-ounce cost down significantly.
Frequently Asked Questions
What is the best medium for acrylic pouring?
Liquitex Professional Pouring Medium is widely considered the gold standard for finish quality, but Flood Floetrol is the best all-around value because it works for both pour art and house painting, produces reliable cells with silicone additives, and costs less per ounce. For beginners on a budget, U.S. Art Supply or Mont Marte offer solid results without the premium price tag.
What can I use instead of pouring medium for acrylic pouring?
You can use Flood Floetrol, Elmer’s Glue-All mixed with water at a 60/40 ratio, or a combination of PVA glue and water. None of these match archival quality, and glue-based DIY recipes can yellow over time, but they work for practice pours and learning ratios. For pieces you plan to sell or keep long-term, a proper pouring medium is worth the cost.
What is the difference between pouring medium and water?
Water dilutes acrylic paint but does not replace the acrylic polymer binder, which leads to cracking, dull colors, and flaking once the water evaporates. Pouring medium thins the paint while preserving binder strength, pigment vibrancy, and adhesion to the canvas. As a rule, never exceed 30 percent water in any pour mixture.
How much pouring medium do I mix with acrylic paint?
Start with 2 parts pouring medium to 1 part Heavy Body acrylic, 1.5 to 1 for Soft Body, and 1 to 1 for Fluid acrylics. Adjust until the paint flows like warm honey when lifted off a stir stick. Add water in teaspoon increments only if the medium alone is not flowing enough, and keep total water below 30 percent of the mixture.
Is Liquitex pouring medium the same as Floetrol?
No, they are different products. Liquitex is a professional acrylic pouring medium designed specifically for fluid art, with high resin solids that dry to a glossy finish. Floetrol is a latex paint additive originally made for house painters that also works as a pouring medium. Liquitex produces better finish quality, while Floetrol is cheaper per ounce and easier for cells when paired with silicone oil.
Final Verdict: Picking the Best Pouring Medium for 2026
After three months of testing 10 different mediums across Dutch pours, dirty pours, tree rings, and puddle pours, Flood Floetrol remains our top pick for the best medium for acrylic pouring. It earned the Editor’s Choice slot because it balances finish quality, versatility, and per-ounce cost better than anything else in this roundup. Liquitex is the runner-up for any artist whose priority is gallery-grade gloss finish. U.S. Art Supply is the best value for hobbyists who want quart-size bottles without the premium price.
Pick the medium that matches your technique and budget. Start with Floetrol if you are unsure, then branch out once you know whether you prefer gloss or satin, cells or smooth finishes. Every medium on this list works, but the right one for you is the one that fits how you actually pour.
