Quick answer: Here is how to use Floetrol with acrylic paint: strain the Floetrol, then mix it with acrylic paint at about 1 part paint to 1 part Floetrol for heavy or craft paints, or about 1 part paint to 2 parts Floetrol for already-fluid paints. Add water a few drops at a time until the mix flows off a stir stick like warm honey, let it rest 10–15 minutes to release bubbles, then pour. Floetrol dries milky but clears, and finished pours generally need a few days to dry and longer to cure before varnishing.
Floetrol is a paint conditioner originally designed to help house paint level out and reduce brush marks. Acrylic pour painters adopted it because it thins paint while keeping colors from muddying together too fast, and it is far cheaper than most artist pouring mediums. It is not magic, though. Using too much, skipping the straining step or rushing the cure causes most of the problems people blame on the product.
This guide explains how to use Floetrol with acrylic paint for pouring, the ratios that work for different paint types, how to get cells, how to dry and seal the finished piece and how Floetrol compares with other pouring mediums.

Can Floetrol Be Used With Acrylic Paint?
Yes. Floetrol is a water-based conditioner, and it mixes readily with acrylic craft paint, student acrylics and artist acrylics. It does three helpful things in a pour:
- Improves flow without the weakening effect of thinning with lots of water.
- Extends open time, giving the paint longer to move and settle before it skins over.
- Helps colors stay distinct, so pours are less likely to blend into mud.
There is one honest caveat. Floetrol is designed for house paint, not artist materials, and it is not marketed as an archival artist medium. Many pour artists use it successfully, but if long-term archival quality is your top priority, an acrylic pouring medium from an artist-paint maker is the more conservative choice.
What You Need
- Floetrol
- Acrylic paints in your chosen palette
- Disposable cups, stir sticks and a measuring cup or graduated cups
- A fine mesh strainer or paint strainer bag
- Distilled or tap water in a squeeze bottle
- Silicone oil or a dimethicone-based product (optional, for cells)
- Primed canvas, panel or wood surface, raised on cups so paint can drip off
- Plastic sheeting, gloves and a level work surface
- A kitchen torch or heat gun (optional, for bubbles and cells)
How to Use Floetrol With Acrylic Paint: Step by Step
- Strain the Floetrol. It often contains small rubbery clumps. Pour it through a fine strainer into a clean container once, and you will avoid lumps in your pour.
- Measure the paint. Pour each color into its own cup. Note the paint type, because heavy and fluid paints need different ratios.
- Add Floetrol. Start at 1:1 paint to Floetrol for craft and heavy body paints, or 1:2 for fluid paints.
- Stir slowly and thoroughly. Scrape the cup’s sides and bottom for about a minute. Fast stirring adds bubbles.
- Adjust with water. Add water a few drops at a time until the mix runs off the stick in a smooth stream that mounds briefly on the surface before leveling. “Warm honey” is the usual description.
- Add silicone (optional). For cells, add 1–3 drops of silicone oil per 4 ounces of mixed paint and stir only two or three times.
- Rest the paint. Let mixed cups sit for 10–15 minutes so trapped air rises out.
- Pour. Use your chosen technique: flip cup, puddle, swipe, tree ring or dirty pour.
- Tilt to cover. Tilt the surface gently so paint flows to and over the edges.
- Torch lightly (optional). Pass a torch quickly over the surface to pop bubbles and encourage cells. Keep it moving; holding it in place scorches paint.
- Dry level and covered. Leave the piece on a level surface, covered loosely to keep off dust, away from drafts.
Floetrol ratio chart
| Paint type | Paint : Floetrol | Water | Notes |
|---|---|---|---|
| Craft acrylic (bottle) | 1 : 1 | Small amount as needed | Most common starting point |
| Heavy body tube | 1 : 1 to 1 : 1.5 | More water usually needed | Pre-mix paint with a little water first |
| Soft body / fluid | 1 : 1.5 to 1 : 2 | Little or none | Already thin; add Floetrol for flow and open time |
| Metallic or fluorescent | 1 : 1 | As needed | Test first; some lose a little intensity |
| White base color | 1 : 1 | Slightly thicker than other colors | A thicker white often helps cells form |
Ratios are starting points. Paints from different brands vary in thickness, so consistency matters more than exact numbers.
How to Make Acrylic Paint Flow Smoothly
Smooth flow is about matching consistencies. When every color in a pour has roughly the same thickness, they move together and cells form evenly. If one color is much thinner, it rushes over the others and can sink beneath them.
- Use the drip test. Lift your stir stick; the paint should flow in a continuous ribbon without breaking into drops immediately.
- Check each cup against the others before pouring. Adjust thicker cups with water a few drops at a time.
- Avoid more than about 25–30 percent water in the final mix. Too much water weakens the binder and leads to cracking.
- Keep paint at room temperature. Cold paint is thicker and behaves unpredictably.
Getting Cells With Floetrol
Cells are the circular patterns pour artists chase. They form when colors with different densities and surface tensions push through one another. Floetrol helps on its own, especially when combined with a heavier base color.
- Silicone oil: the most common cell booster. Use sparingly: too much creates tiny, crowded cells and oily residue.
- Density differences: pigments vary in weight. Titanium white is relatively dense and tends to sink, letting lighter colors rise through it.
- Heat: a quick torch pass lowers surface tension and pulls silicone to the surface, opening cells.
- Swipe technique: dragging a thin layer of white across colored paint with a damp paper towel often reveals cells.
How to Make Fluorescent Paint Work in a Floetrol Pour
Fluorescent acrylics are popular in pours because the cells glow under black light. A few adjustments help:
- Prime the surface white. Fluorescent pigments are transparent and need a bright ground.
- Avoid using black or dark earth colors in the same pour if you want maximum glow; they dull fluorescents where colors mingle.
- Mix fluorescents with Floetrol at the same ratio as other colors, and test a small cup first.
- Check the dried piece under a UV-A light before varnishing.
Drying, Curing and Sealing
Floetrol extends open time, so pours dry more slowly than plain acrylic.
- Touch-dry: often 24–72 hours, depending on thickness and humidity.
- Fully cured: thick pours can take several weeks to cure through the layer.
- Milky patches: Floetrol dries cloudy at first and clears as it dries. Wait before judging the result.
- Varnishing: wait until the piece is fully cured, then remove silicone residue by wiping gently with a mild dish soap and water solution or a little cornstarch. Apply a gloss varnish or resin.
How to Make Acrylic Paint Flexible
Pour paintings on canvas can crack if the paint layer is thick and brittle. To keep the film flexible:
- Do not overdilute with water.
- Add a portion of acrylic pouring medium or a flexible acrylic medium alongside Floetrol for more binder.
- Avoid very thick puddles in one spot, which shrink unevenly as they dry.
- Dry in a stable room temperature, away from fans and heaters.
Floetrol vs Other Pouring Mediums
| Medium | Cost | Finish | Archival intent | Notes |
|---|---|---|---|---|
| Floetrol | Low | Satin; dries clear after milky stage | Not marketed as archival | Strain first; good for cells |
| Artist acrylic pouring medium | Medium to high | Gloss or satin | Designed for artists | Adds binder; very smooth |
| PVA glue mixes | Low | Variable | Not archival | Can yellow or stay tacky |
| Water only | Free | Variable | Weakens film | Risk of cracking and muddy colors |
Flashe paint vs acrylic in pours
Flashe, a vinyl-based matte paint, is not commonly used for pouring and behaves differently from acrylic with additives. If you want to experiment, test it in a small pour first rather than assuming Floetrol ratios carry over.
Troubleshooting Floetrol Pours
- Cracks or crazing: too much water, too thick a layer or rapid drying. Reduce water and dry away from heat.
- Muddy colors: paint too thin or too much tilting. Thicken slightly and tilt less.
- Lumps on the surface: unstrained Floetrol. Strain every new bottle.
- Craters or fish-eyes: too much silicone. Use fewer drops and stir less.
- Paint sliding off edges and leaving bare spots: mix too thin, or not enough paint for the canvas size.
- Dull color after drying: normal acrylic darkening plus Floetrol dilution; a gloss varnish restores depth.
Choosing Colors and Pour Techniques for Floetrol
Ratios get the paint flowing; color planning decides whether the finished pour looks deliberate or muddy.
- Limit the palette. Three to five colors, including a white or neutral, usually give clearer results than eight colors fighting each other.
- Avoid complementary colors touching heavily if you want clean color. Blue and orange mixed in a pour can turn brownish where they blend.
- Use a strong contrast color. White, black or metallic between brighter colors helps cells and lacing stand out.
- Consider transparency. Transparent colors create depth when layered; opaque colors give crisp edges.
Common pour techniques with Floetrol
- Flip cup: layer colors in a cup, flip it onto the canvas, lift and tilt. Reliable for cells.
- Puddle pour: pour puddles of color on top of each other, then tilt outward for organic rings.
- Swipe: pour colors in stripes, lay a thin coat of white or a contrasting color along one edge and drag it lightly across.
- Tree ring: pour from a layered cup in a slow, small circular motion to build concentric rings.
- Dirty pour: combine all colors in one cup without mixing, then pour, giving unpredictable patterns.
Each technique benefits from consistent paint thickness across all cups. If one technique keeps failing, check consistency first before changing the ratio.
Surface Prep for Floetrol Pours
The surface you pour onto affects how the paint settles. Primed stretched canvas is the most common, but wood panels, tiles and coasters work too. Seal raw wood first so it does not absorb the paint unevenly. Check that the surface is level with a small spirit level before pouring, because even a slight slope makes thick pours slide and pool toward one edge as they dry. Tape the back of canvases to make cleanup of drips easier.
FAQs
What is the best ratio of Floetrol to acrylic paint?
Start at 1:1 for craft and heavy paints and 1:2 paint to Floetrol for fluid paints, then adjust with water until the mix flows like warm honey.
Do I need to add water if I use Floetrol?
Usually a little, especially with thicker paints. Add it a few drops at a time and keep water below about a quarter to a third of the mix.
Why is my Floetrol pour cloudy?
Floetrol dries milky and becomes clear as moisture leaves. Give the pour more time before judging, and dry in moderate humidity.
Can I use Floetrol without silicone?
Yes. Floetrol can produce cells on its own, especially with a heavier white and some heat. Silicone just makes cells more frequent.
How long should a Floetrol pour dry before varnishing?
Wait until the piece is fully cured. Thin pours may be ready in days, while thick pours can take several weeks. Clean off silicone residue before varnishing.
Is Floetrol safe to use indoors?
It is water-based, but you should still follow the label: ventilate the room, wear gloves and keep it away from food and children.
Final Thoughts
Floetrol is an affordable, effective way to turn acrylic paint into a smooth pouring consistency, provided you strain it, match consistencies, go easy on water and silicone, and give the piece plenty of time to cure. Once your ratios are dialed in, color choice becomes the fun part.
