Quick answer: To use liquid watercolor, shake the bottle, put a few drops into a palette well and dilute with water to the strength you want: a drop or two per teaspoon for light washes, or straight from the bottle for intense color. Paint on watercolor paper with soft brushes, droppers or sprayers, working wet-in-wet for blooms or wet-on-dry for control. Because the color is concentrated and can stain, start pale and build up in layers.
Liquid watercolor arrives as a bottle of intensely colored fluid rather than a tube or pan. It mixes instantly, flows beautifully and can be dropped, sprayed or brushed. It also behaves a little differently from tube paint, which can surprise painters used to traditional formats. Knowing how to use liquid watercolor well means understanding its strength, its staining tendency and the techniques it does best.
This guide covers what liquid watercolor is, how to dilute it, the tools and papers that suit it, step-by-step techniques and how it compares with tube and pan watercolor. Brushes make a big difference with such fluid paint; our guide to Liquitex watercolor brushes looks at synthetic options that handle fluid color well.
What Liquid Watercolor Is
Liquid watercolor is pigment or dye suspended in water with a binder, ready to use without rewetting. Products in this category vary:
- Pigment-based liquid watercolors behave much like diluted tube watercolor and can be more lightfast.
- Dye-based liquid watercolors are extremely vibrant and transparent but often less lightfast, so they may fade with prolonged light exposure.
- Classroom liquid watercolors are formulated for children’s art, with an emphasis on washability and bright color.
Check the label. If longevity matters, choose a product that lists lightfastness ratings or pigment information.

| Lightfastness | Varies widely; dye-based often lower | Generally good in artist grades | Generally good in artist grades |
| Best for | Illustration, washes, pours, spray effects | All-round painting | Sketching and travel |
Supplies for Liquid Watercolor
- Paper: 140 lb (300 gsm) watercolor paper handles heavy, wet application without buckling as much. Cold-press is versatile; hot-press shows color brilliance and suits illustration.
- Brushes: soft rounds and flats with good water capacity. Synthetic brushes are easy to clean after staining colors.
- Palette: a white ceramic or plastic palette with wells, so you can see true color strength.
- Droppers or pipettes: for precise color placement and mixing.
- Spray bottle: for misting paper or creating spray effects.
- Masking tape: to tape paper down and reduce buckling.
- Paper towels: for blotting and lifting.
How to Use Liquid Watercolor Step by Step
- Prepare the paper. Tape watercolor paper to a board on all four sides. For heavy washes, you can stretch the paper first by soaking and taping it.
- Shake the bottle. Pigment-based liquids can settle. Shake gently before opening.
- Dispense a small amount. Use the dropper or pour a few drops into a palette well. A little goes a long way.
- Dilute to strength. Add water a few drops at a time. Test on scrap paper to check the value.
- Plan light to dark. Like all watercolor, liquid watercolor is transparent. Reserve whites by leaving paper bare or masking it.
- Apply the first wash. Paint large areas with a big brush, working quickly while the paint flows.
- Let it dry. Wait until the paper is dry, then layer more color for depth.
- Add details. Use stronger, less diluted color and a smaller brush for final details.
Dilution Guide
| Desired effect | Approximate dilution |
|---|---|
| Pale tint for skies and backgrounds | 1 drop per 1–2 teaspoons water |
| Medium wash | 3–5 drops per teaspoon water |
| Rich color | Equal parts paint and water |
| Maximum intensity | Undiluted |
Concentrations vary between brands, so treat these as starting points and adjust after testing.
Liquid Watercolor Techniques
Wet-in-wet
Wet the paper evenly with clean water, then touch the brush or dropper loaded with color to the surface. The color spreads and blooms. Liquid watercolor is particularly vivid in this technique because it disperses quickly.
Wet-on-dry
Paint onto dry paper for crisp edges and controlled shapes. This works well for illustration and line-and-wash.
Dropper painting
Drop concentrated color directly onto wet paper. Tilt the board to guide runs and create organic blends.
Spray and splatter
Fill a fine-mist spray bottle with diluted liquid watercolor and spray over stencils or leaves for silhouettes, or flick a loaded brush for splatter textures.
Salt texture
Sprinkle coarse salt into a wet wash. As the paint dries, salt absorbs pigment and creates starburst patterns. Brush off the salt once dry.
Glazing
Layer thin, transparent washes over dry layers to shift color and deepen shadows. Allow each layer to dry thoroughly.
Dry brush
Use a nearly dry brush with concentrated color for texture. Liquid watercolor’s intensity makes dry-brush marks strong even with very little paint.
Using Liquid Watercolor With Other Media
- Ink: combine with waterproof ink line work for illustration.
- Colored pencil: add details over dried washes.
- Acrylic mediums: some artists mix liquid watercolor into acrylic mediums for glazes or pours. Results vary by product.
- Resist techniques: wax crayons, oil pastels or masking fluid resist liquid watercolor washes.
How to Use Liquitex Gloss Medium With Watercolor Effects
Gloss medium is an acrylic polymer medium, not a watercolor medium. However, some mixed-media painters use acrylic gloss medium to seal a finished watercolor or to create a glazing layer over it. If you do this, test first: brushing a wet medium over watercolor can reactivate and smear the paint. A light spray fixative or a quick, single pass with a soft brush reduces the risk.
Common Mistakes With Liquid Watercolor
- Using too much undiluted paint. Colors can become garish and stain the paper permanently. Start diluted.
- Using thin paper. Lightweight paper buckles and pills under heavy washes.
- Not testing staining. Some liquid watercolors stain strongly, making lifting or correcting difficult.
- Ignoring lightfastness. Dye-based liquids can fade in sunlight; keep finished work out of direct sun or scan it.
- Contaminating the bottle. Never dip a dirty brush into the bottle. Always dispense into a palette.
Storage and Cleanup
- Close bottles tightly to prevent evaporation and spills.
- Store away from heat and sunlight.
- Rinse brushes thoroughly with water after use; mild soap helps remove staining colors.
- Clean palettes promptly, as some dyes can stain plastic.
Watercolor Brushes vs Acrylic Brushes for Liquid Watercolor
Watercolor brushes hold more water and release it smoothly, which suits the fluid nature of liquid watercolor. Acrylic brushes are stiffer and hold less, making them better for controlled strokes or texture. For washes, a soft watercolor brush is the better choice.
Step-by-Step Project: A Glowing Sunset Sky
A sunset sky is a perfect first project because it plays to liquid watercolor’s strengths: intense color and smooth blending.
Colors
- A warm yellow
- An orange or red-orange
- A magenta or crimson
- A deep blue or violet
Steps
- Tape and wet. Tape a sheet of 140 lb cold-press paper to a board. Wet the sky area evenly with clean water until it has a soft sheen, not puddles.
- Lay the yellow band. Brush diluted yellow across the lower third of the sky, near the horizon.
- Add orange above. While the paper is still wet, brush orange just above the yellow, letting the edges overlap and blend.
- Add magenta. Continue upward with magenta, blending into the orange.
- Finish with blue or violet. At the top, add the deep color. Avoid brushing it directly into the yellow, which can turn green or muddy.
- Tilt the board. Tip the board slightly so colors flow gently into each other.
- Dry flat. Let the sky dry completely flat.
- Add a silhouette. Once dry, paint a landscape silhouette, such as trees or hills, with a dark mix of blue and magenta used nearly undiluted.
Mixing Colors With Liquid Watercolor
Because liquid watercolor is so concentrated, mixing behaves a little differently from tube paint.
- Mix in the palette, not on paper, when accuracy matters. Drops blend instantly in a well, so you can judge the mix before painting.
- Add the stronger color in tiny amounts. A single drop of a dark color can overpower a light one.
- Use a limited palette. A warm and cool version of each primary can mix a wide range of hues and keeps mixtures cleaner.
- Watch for mud. Complementary colors, such as orange and blue, neutralize each other. That is useful for shadows but can dull a painting if overused.
Paper Behavior With Very Wet Media
Liquid watercolor is often applied wetter than tube paint, so paper choice and preparation matter.
| Paper | Behavior | Recommendation |
|---|---|---|
| 90 lb (190 gsm) | Buckles significantly when soaked | Use for small studies or stretch first |
| 140 lb (300 gsm) | Some buckling; flattens when taped | Good all-round choice |
| 300 lb (640 gsm) | Stays nearly flat | Ideal for heavy washes, no stretching needed |
| Mixed-media paper | Handles moderate washes | Fine for illustration and practice |
To stretch paper, soak it briefly in water, lay it on a board, and tape the edges with gummed paper tape. As it dries, it tightens and stays flatter during painting.
Liquid Watercolor Tips by Skill Level
Beginners
- Work with two or three colors at first to learn how strong each one is.
- Keep a scrap strip beside your painting and test every mix before it touches the main sheet.
- Practice flat and graded washes on small cards before starting full paintings.
Intermediate painters
- Combine dropper work with brushwork: drop color into wet areas, then refine shapes once dry.
- Use masking fluid to reserve highlights before laying intense washes.
- Explore glazing, layering transparent liquid colors to create depth without mud.
Advanced painters
- Use liquid watercolor alongside tube paint, reserving liquids for the most saturated accents.
- Experiment with airbrush or fine spray bottles for gradient backgrounds.
- Scan or photograph work done with dye-based liquids promptly, so you have a record before any fading.
Lightfastness: Protecting Finished Work
Because some liquid watercolors are dye-based, it is worth taking simple steps to protect finished pieces.
- Run a window test. Paint swatches of each color, cover half of each swatch with card, and tape the sheet in a sunny window for several weeks. Comparing the two halves shows which colors fade.
- Frame with UV-filtering glazing if work will hang in a bright room.
- Display away from direct sunlight regardless of the paint you use.
- Digitize originals intended for prints or portfolios soon after finishing.
Quick Setup Checklist
- Paper taped down on all four sides
- Bottles shaken and a few drops dispensed into a white palette
- Two water jars, one for rinsing and one clean
- Scrap strip of the same paper for testing strength
- Paper towels within reach for blotting and lifting
- Masking fluid applied and dry, if you are reserving highlights
FAQs
Do you need to dilute liquid watercolor?
Not always, but most painters dilute it because it is very concentrated. Undiluted color is useful for intense accents and small details.
Can you use liquid watercolor on canvas?
Not on standard primed canvas, which is not absorbent enough. Use watercolor paper or a canvas prepared with absorbent watercolor ground.
Is liquid watercolor permanent?
It depends on the formula. Pigment-based liquids are generally more lightfast; dye-based liquids are often vivid but can fade over time.
How do you use liquid watercolor for kids’ projects?
Dilute heavily, use thick paper, and try techniques like dropper painting, salt texture and spray art. Choose washable classroom formulas for easy cleanup.
Can liquid watercolor be reactivated?
Some liquid watercolors can be rewetted after drying, while others stain and stay put. Check the product and test on scrap paper.
Is Liquitex acrylic paint water based?
Yes, Liquitex acrylics are water-based while wet and clean up with water, but they dry into a permanent, water-resistant film unlike watercolor.
Final Thoughts
Liquid watercolor rewards a light touch: dilute generously, test strength, build from pale to dark and lean into its strengths for washes, drops and sprays. Pair it with soft, absorbent brushes and heavy paper for the best results.
