Quick answer: How to prep for acrylic painting comes down to a few steps: cover your work area, set out two water jars and paper towels, and prepare your surface: most pre-primed canvases are ready to use, while raw wood, paper or cardboard usually need a coat or two of acrylic gesso. Squeeze small amounts of paint onto a palette (a stay-wet palette keeps it usable longer), dampen your brushes, plan your composition with a light sketch, and keep a spray bottle handy so paint does not dry too fast.
A painting session often goes wrong before the first stroke. Paint dries on the palette while you hunt for a brush, the canvas soaks up color unevenly, or the table ends up covered in stains. Ten minutes of preparation prevents most of that.
This guide explains how to prep for acrylic painting in four parts: the workspace, the surface, the palette and brushes, and the plan for the painting itself. It also includes a quick checklist, kid-specific setup tips and fixes for common prep mistakes. If you are preparing a painting space for children, our guide to the best acrylic paint sets for kids can help you choose suitable paints first.
Part 1: Prepare Your Workspace
Choose the spot
Good light comes first. Daylight from a window to one side, or a daylight-balanced lamp, shows colors more accurately than warm household bulbs. Place your surface so your painting hand does not cast a shadow on it.
Protect surfaces
- Cover tables with a plastic tablecloth, drop cloth, newspaper or a silicone mat.
- Put a mat or old sheet on the floor under easels.
- Wear an apron or old clothes; dried acrylic is very difficult to remove from fabric.
- Keep wet wipes or a damp cloth nearby for quick cleanup of drips.
Arrange your tools
Set up on the side of your painting hand: palette closest, then water jars, then brushes and paper towels. Everything should be reachable without stretching across the painting.
Ventilation and safety
Acrylics are water-based and low-odor, but ventilation is still sensible, especially with mediums, sprays or varnishes. Avoid eating and drinking near the palette, and wash hands after painting. Read labels; some artist pigments carry caution labels.
Part 2: Prepare Your Painting Surface
How you prep a surface depends on what it is. The goal is a surface that is clean, stable and appropriately absorbent so paint adheres well and colors stay vibrant.
| Surface | Usually pre-primed? | Prep steps |
|---|---|---|
| Stretched canvas (store-bought) | Usually yes | Ready to use; optionally add one coat of gesso for a smoother or less absorbent surface |
| Canvas panel or board | Usually yes | Ready to use; check for warping |
| Acrylic or canvas paper pad | Yes | Tape edges to a board to reduce curling |
| Raw wood panel | No | Sand lightly, wipe dust, seal or prime with acrylic gesso (two or more thin coats) |
| Heavy paper or watercolor paper | No | Can paint directly; a gesso coat reduces absorbency and buckling |
| Cardboard or MDF | No | Seal both sides with gesso or medium to reduce warping |
| Rocks, wood crafts, terracotta | No | Clean, dry, then prime; seal finished work for durability |
How to apply gesso
- Stir the gesso rather than shaking, to avoid bubbles.
- Thin the first coat slightly with a little water if the manufacturer allows, so it penetrates the surface.
- Apply with a wide flat brush in one direction.
- Let it dry according to the label, often under an hour for thin coats.
- Apply a second coat in the perpendicular direction for even coverage.
- Sand lightly between coats with fine sandpaper if you want a very smooth finish.
Tone the surface (optional)
Many painters cover a bright white surface with a thin, mid-value wash before starting. Common choices are burnt sienna, yellow ochre or a neutral gray, thinned with water or medium. A toned ground makes values easier to judge and removes the intimidation of a blank white canvas.
Tape the edges
Painter’s tape around a paper or panel creates a clean border and holds paper flat. Remove tape slowly at a low angle once the paint is dry to the touch.
Part 3: Prepare Your Palette and Brushes
Choose a palette
- Plastic palette: inexpensive; dried acrylic peels off once dry.
- Glass or ceramic plate: easy to scrape and clean.
- Disposable palette paper: convenient for quick cleanup.
- Stay-wet palette: a damp sponge or paper under a membrane keeps acrylics workable for much longer.
Make a simple stay-wet palette
- Take a shallow airtight container.
- Lay a damp paper towel or thin sponge in the bottom.
- Place a sheet of baking parchment on top.
- Squeeze paint onto the parchment; moisture rises through it and slows drying.
- Close the lid between sessions to keep paint usable longer.
Lay out your paint
Squeeze small amounts, about the size of a pea or coin, and add more as needed. Arrange colors in a consistent order every time, for example white on one end, then yellows, reds, blues and earths. Leave a large open area in the middle for mixing.
Prepare brushes
- Dip brushes in clean water and blot them before use, so paint does not dry in the bristles near the ferrule as quickly.
- Have at least one large brush for blocking in, one medium and one small.
- Keep a brush rest or flat surface so wet brushes do not roll into paint.
- Do not leave brushes standing on their bristles in water for long, which can bend them.
Set up water jars
Use two jars: one for rinsing off paint and one with clean water for thinning and wetting. Change water when it becomes cloudy to avoid muddy colors.
Part 4: Prepare Your Painting Plan
Choose a reference or idea
Have your reference photo, still life or idea ready before you begin. Painting is easier when you are not deciding everything at once.
Make a thumbnail sketch
Draw a small sketch, a few inches across, showing the main shapes and darkest and lightest areas. This takes a few minutes and reveals composition problems early.
Transfer the sketch
Draw lightly on the surface with a pencil, watercolor pencil or thinned paint. Avoid heavy graphite on light areas; it can smudge into the paint.
Plan the order
A common sequence is background first, then large shapes, then mid-ground, then details and highlights last. Planning the order helps you work with acrylic’s drying time.
Prep Your Paint Consistency and Mediums
Acrylic paint comes in several body types, and knowing which you have helps you prepare the right extras.
| Paint type | Consistency | Prep tip |
|---|---|---|
| Heavy body | Thick, holds brush marks | Have a palette knife ready for mixing; add a little medium for smoother strokes |
| Soft body | Creamy, levels slightly | Ready to use; good all-round choice for beginners |
| Fluid | Pourable | Good for glazing and detail; protect the area from drips |
| Craft acrylic | Varies, often thinner | May need more coats; good for practice and crafts |
Mediums to keep within reach
- Matte or gloss medium: thins paint for glazes without losing adhesion the way excess water can.
- Retarder or slow-drying medium: extends working time for blending.
- Gel medium: thickens paint for texture and impasto.
- Spray bottle of water: the simplest way to keep paint workable.
You do not need all of these to start. Water plus a spray bottle covers most beginner needs; add mediums as your techniques develop.
Warm Up Before the Main Painting
A short warm-up is part of prep too. Spend five minutes on a scrap sheet loading the brush, making a few strokes and mixing two or three colors you plan to use. This checks paint consistency, reveals any brush that has stiffened and settles your hand before you touch the real surface.
Acrylic Painting Prep Checklist
| Task | Done? |
|---|---|
| Table and floor covered | ☐ |
| Apron or old clothes on | ☐ |
| Good light set up | ☐ |
| Surface primed and dry (or confirmed pre-primed) | ☐ |
| Edges taped if needed | ☐ |
| Palette set, paint laid out in order | ☐ |
| Two water jars filled | ☐ |
| Brushes dampened and ready | ☐ |

| Reference and thumbnail sketch ready | ☐ |
How Long Does Prep Take?
| Prep task | Approximate time | Can be done in advance? |
|---|---|---|
| Covering surfaces and setting up tools | 5 minutes | Yes, if you have a dedicated space |
| Priming a raw surface (two coats) | 1–2 hours including drying | Yes, prime several at once |
| Toning the surface | 5 minutes plus drying | Yes |
| Laying out the palette | 3–5 minutes | Partly, with a stay-wet palette |

Batching the slow tasks, especially priming and toning, on a separate day means each painting session starts almost immediately.
Prepping for Acrylic Painting With Kids
Children’s painting sessions go more smoothly when prep is done before they sit down.
- Pre-squeeze paint into small cups or a muffin tin so kids do not empty tubes.
- Use washable surfaces and cover chairs as well as tables.
- Give each child their own water cup, preferably weighted or wide-based to prevent spills.
- Set out fewer colors: primaries plus white encourage mixing and reduce mess.
- Use sturdy surfaces like canvas panels or thick card, which stand up to enthusiastic brushing.
- Check paint labels for the AP non-toxic seal and supervise younger children closely.
- Plan cleanup: a bucket of soapy water for brushes and a towel for hands.
Choosing the right paints is part of good prep for children. For sets with non-toxic labels and manageable color ranges, see our list of acrylic paint kits suited to kids.
Common Prep Mistakes and Fixes
| Mistake | What happens | Fix |
|---|---|---|
| Skipping primer on raw wood or cardboard | Paint soaks in, colors look dull, surface may warp | Prime with acrylic gesso before painting |
| Squeezing too much paint | Paint dries and goes to waste | Start small, refill as needed |
| One water jar only | Muddy colors | Use separate rinse and clean water jars |
| Dry brushes | Paint dries in the bristles faster | Dampen and blot before painting |
| No plan | Overworked, muddy painting | Make a quick thumbnail sketch |
| Painting under warm yellow light | Colors look different in daylight | Use daylight or daylight-balanced bulbs |
| Heavy pencil lines | Graphite smears into light colors | Sketch lightly or with thinned paint |
Prep for Different Kinds of Acrylic Projects
- Canvas painting: follow the full sequence above, with a toned ground if you like.
- Rock and craft painting: clean and dry the object, prime it, and plan to seal the finished piece.
- Acrylic pouring: level the surface, raise it on cups to let paint drip off, and cover a wider area than usual.
- Outdoor painting: pack a stay-wet palette, extra water and clips to hold paper against wind.
After-Session Prep for Next Time
Good prep for the next session starts at the end of this one.
- Close the stay-wet palette or cover leftover paint with plastic wrap.
- Wash brushes thoroughly with mild soap, reshape and dry them.
- Empty and rinse water jars.
- Prime a few surfaces in advance so they are ready when inspiration strikes.
- Note which colors are running low.
FAQs
Do I need to prime a canvas before acrylic painting?
Most store-bought canvases are already primed and ready to use. Raw canvas, wood, cardboard and other unprimed surfaces should usually be primed with acrylic gesso.
Should I wet the canvas before painting with acrylics?
Not usually. A lightly misted surface can help with soft blending, but a soaked surface can dilute paint and affect adhesion.
How long should gesso dry before painting?
Thin coats often feel dry within an hour, but drying times vary with thickness and humidity. Follow the manufacturer’s label and wait longer for thick coats.
How do I keep acrylic paint from drying on the palette?
Use a stay-wet palette, put out small amounts, and mist the paint with water occasionally.
What is the best surface for beginners?
Canvas panels and acrylic paper pads are affordable, ready to use and good for practice.
How do I prepare a painting area for kids?
Cover all surfaces, pre-portion paint, give each child their own water cup and smock, and choose non-toxic, AP-labeled paints.
