Essential Watercolor Painting Supplies
Everything you need to start painting with watercolors — paint, paper, brushes, palette, water setup, and the small essentials.
Watercolor paint (24–36 colors)
An artist-grade 24 or 36-colour tube or pan set is the foundation. 12 ml tubes last 50+ small paintings per colour, and pans last even longer. Chalkola's 36-colour tube set at $29.95 covers paint + palette + brushes in one purchase, and the 48-pan professional set at $37.95 delivers XL semi-moist pans with 8 metallics and 6 fluorescents.
See our choosing guide for full details on student vs artist vs professional grade, pan vs tube, and colour count recommendations.
Why can't I use regular paper for watercolor?
Regular printer paper (~20 lb) buckles, tears, and can't hold water. Watercolor paper (140 lb / 300 gsm minimum) is made thick and sized to absorb and hold water without falling apart. Paper is the one non-negotiable supply — bad paper ruins good paint.
- Cold-pressed — medium texture, versatile. Most beginners use cold-pressed.
- Hot-pressed — smooth texture, best for botanical illustration and detail.
- Rough — pronounced texture, best for loose landscapes.
- 100% cotton (Arches, Saunders, Fabriano) is archival but expensive. Cellulose blends are cheaper and fine for practice.
Buy a student watercolor pad ($10–20) for practice. Upgrade to 100% cotton sheets when you're painting pieces worth keeping.
How many brushes do I really need?
Three is enough: a small (size 4) round for detail, a medium (size 8) round for general work, and a large (size 12) round for washes. Optional fourth: a mop brush (size 12–20) for huge sky washes. Most painters add a flat wash brush later.
Hair type: Squirrel hair holds the most water (premium). Sable is traditional, springy, expensive. Synthetic (taklon) is cheap and works fine for beginners — get these first. Budget $15–25 for a good starter set of three.
Palette or mixing tray
Options:
- Plastic palette with wells ($5–10) — squeeze tube colors into wells, mix in the flat center. Most common.
- Ceramic palette ($15–25) — doesn't stain, professional feel, more expensive.
- Portable palette tin for pan sets — included with the paint.
Two water jars + paper towels
Use two jars: one for rinsing brushes (will get muddy), one for clean water to dilute paint. Change them when they get too dirty — mud in your water = mud in your painting.
Paper towels or a lint-free cloth for blotting brushes — essential for water control. Many painters keep a small spray bottle nearby to mist paper or reactivate a drying wash.
Optional extras
- Masking fluid ($10) — rubber latex that preserves white paper areas. Peel off at the end to reveal untouched paper.
- Watercolor ground — a gesso-like primer that lets you paint watercolor on wood, canvas, or other non-paper surfaces.
- Salt — kitchen salt sprinkled on wet paint creates textured blooms (for sand, snow, galaxy effects).
- Spray bottle — keeps paper damp for longer, controls wet-on-wet work.
- Masking tape — creates clean edges around your painting.

Frequently asked questions
Why can't I use regular paper for watercolor?
Regular printer paper (~20 lb) buckles, tears, and can't hold water. Watercolor paper (140 lb / 300 gsm) is made thick and sized so it absorbs and holds water without falling apart. This is the one non-negotiable supply — bad paper will ruin even good paint.
How many brushes do I really need?
Three: a small (size 4) round for detail, a medium (size 8) round for general work, and a large (size 12) round for washes. Most intermediate painters add a mop brush and a flat wash brush later. Budget $15–25 for a good starter set of three.
Do I need 100% cotton watercolor paper?
Not to start. Cellulose student paper ($10–20/pad) is fine for practice. Upgrade to 100% cotton ($30–60/pad) when you're painting pieces you want to last — cotton takes water beautifully and has better archival stability than wood-pulp paper.
Can I use synthetic brushes for watercolor?
Yes — synthetic brushes (taklon, nylon) are a perfect beginner choice. Cheaper than sable, springy, easy to maintain. Upgrade to natural hair (squirrel, sable) once you're serious about wash control and want the maximum water-holding capacity.
What's masking fluid and do I need it?
Masking fluid is liquid latex you paint on paper to preserve white areas. When dry, you paint over it; at the end, you rub off the mask to reveal untouched paper. Useful for tricky highlights (star-speckled skies, water sparkle, fine branches) but not essential for beginners.
Can I paint watercolor on canvas?
Not directly — paint beads up on primed canvas. You need watercolor ground first, a gesso-like primer that gives canvas a paper-like texture. Once the ground dries, watercolor behaves normally. Traditional watercolor paper remains the preferred surface for most painters.
