Poster paint is the bright, opaque, matte paint most of us remember from school: thick enough to cover poster board in one coat, easy to mix, and in kids’ versions washable from skin and most clothing. In the US it is usually sold as washable tempera or “classic” kids’ paint. The best poster paints for kids give strong, even coverage for posters, signs and school projects, come in bottles large enough for big sheets, and carry clear non-toxic labeling.
This guide compares five poster and tempera paints on Amazon, from AP-certified classroom tempera in 8 oz bottles to a 42-color kit with brushes and a bucket, a bulk 8-color pack, Crayola’s washable project paint and a toddler-friendly finger paint set. It also covers how to paint a poster that looks sharp, which surfaces work best and how to stop poster paint from cracking.
Quick answer: For most families and classrooms, Colorations Washable Tempera is the best poster paint for kids: six 8 oz bottles of opaque color that the listing says will not chip, flake or crack when dry, AP-certified non-toxic, paraben-free and free of common allergens such as latex, gluten and nuts. For more colors plus tools, the TMOL 42-color washable tempera kit includes brushes, palettes and a foldable bucket. On a budget, the Cra-Z-Art 8-color bulk pack gives you 4 oz bottles of the essential colors, including white and black.

How to Paint a Poster That Looks Sharp
- Plan in pencil. Lightly sketch the layout and lettering on the poster board.
- Paint the background first with a large flat brush or a sponge roller.
- Let it dry completely before adding anything on top.
- Paint large shapes next, then smaller details.
- Letter last with a medium round brush, or outline letters in marker and fill with paint.
- Keep paint layers thin; thick tempera can crack as it dries.
- Dry flat so paint does not run.
Best Surfaces for Poster Paint
| Surface | Result | Tip |
|---|---|---|
| Poster board | Bright, flat color | The classic choice; paint on the matte side |
| Heavy paper or cardstock | Good coverage | Tape edges to limit curling |
| Cardboard | Great for signs and models | Prime brown cardboard with white for brighter colors |
| Papier-mâché | Opaque coverage | Let papier-mâché dry fully first |
| Plastic or glossy surfaces | Poor; may flake | Use acrylic instead |
Mixing Colors With Poster Paint
Poster paint is one of the best ways for kids to learn color mixing because it is opaque and dries close to its wet color. A simple mixing lesson needs only red, yellow, blue, white and black:
- Secondary colors: red + yellow = orange, yellow + blue = green, blue + red = purple.
- Tints: add a little color to white (not the other way round) to make pastels.
- Shades: add a tiny amount of black, or the color’s opposite, to darken.
- Browns: mix all three primaries, or orange with a little blue.
- Skin tones: start with white plus a little orange or yellow ochre-style mix, then adjust with red and brown.
Mix in cups, muffin tins or on paper plates, and keep a “mixing brush” separate from painting brushes so the main colors stay clean.
Lettering Tips for Posters
- Draw a light pencil baseline and cap line so letters stay the same height.
- Sketch letters in pencil first and check spacing from across the room.
- Choose a color with strong contrast against the background, such as dark on light.
- Paint the letter outlines with a small round brush, then fill with a slightly larger brush.
- For crisp edges, outline dry letters with a black or white paint marker.
Classroom and Group Setup
For groups, pour poster paint into small lidded cups or muffin tins shared between two to four children, with one brush per color. Put the large bottles out of reach so refills go through an adult. Lay posters on tables covered with kraft paper, and set up a drying line or rack before the activity starts. Washable tempera makes group cleanup manageable: sponge tables, collect brushes in a soapy bucket, and send smocks home or into the wash.
School Projects and Science Fair Boards
Poster paint shines on project boards, maps, timelines and model backgrounds. Paint large color areas on the board before gluing on printed text and photos, since glue does not stick well to wet paint and paint does not cover printed paper neatly. Keep paint layers thin on trifold boards so they can still fold without cracking, and let everything dry overnight before transporting the project to school.
Kid Projects That Suit Poster Paint
Poster paint is perfect for bold, simple images like our easy ladybug painting and easy dinosaur painting. For rocks, which handle and weather more, acrylic lasts longer, as in our painted rock critters tutorial.
Cleaning Up Poster Paint
Washable tempera is designed to make cleanup easy, but timing still matters. Rinse brushes in water as soon as the session ends, then wash them with a little soap and reshape the bristles. Wipe tables with a damp sponge while paint is still soft; dried tempera usually lifts with warm water but may need a little scrubbing on porous surfaces. For clothing, rinse the back of the fabric under cool water to push paint out, then launder as normal. Avoid hot water on fresh stains, which can set some pigments. Check any carpet or upholstery spill quickly with a damp cloth, blotting rather than rubbing.
How Long Does Poster Paint Last?
Sealed bottles of tempera keep well for a long time at room temperature. Once opened, keep caps clean and tightly closed so the paint does not thicken. Tempera is water-based and can occasionally spoil if contaminated with dirty water or brushes, which shows up as an unusual sour smell; discard paint if that happens. Pouring out only what you need, rather than dipping brushes straight into bottles, is the best way to keep paint fresh.
Buying Guide: How to Choose Poster Paint for Kids
Opacity
Good poster paint covers in one coat; cheaper paint may need two.
Washability
Choose washable formulas for younger kids and classrooms.
Safety labels
Look for the AP seal or ASTM D4236, and check allergen information if needed.
Bottle size
Large posters and classrooms need 4 to 8 oz bottles.
White and black
Sets that include them allow kids to mix tints and shades.
Matte finish
Poster paint is prized for its flat, glare-free look, which photographs well for school displays and reads clearly from a distance. If a paint is described as glossy, expect a slight shine; that is fine for decorations but less ideal for presentation boards under bright lights.
Crack resistance
Paints described as not chipping or cracking hold up better on finished posters.
Common Mistakes to Avoid
- Painting thick layers. Tempera can crack.
- Rolling posters while wet. Let them dry flat first.
- Using poster paint on plastic. It flakes.
- Leaving caps open. Tempera thickens and can spoil.
- Skipping a pencil plan. Lettering ends up crowded.
- Mixing colors in the bottle. Mix in a cup or palette.
