What you actually need when you're about to start an acrylic painting

Most people overcomplicate this. You need a surface, paint, brushes, water, and somewhere to work. The rest is decision fatigue. I spent years building a proper checklist for acrylic painting that cuts through the noise because I kept watching beginners waste hours on the wrong supplies or show up to a session and realize they forgot the medium they needed.

The Checklist For Acrylic Painting Ultimate

Surface Cotton rag canvas is my preference for anything serious. Acid-free is non-negotiable. Stretch your own canvas or buy pre-primed. I once showed up to a group session with one stretched panel and realized too late it was unstretched — had to skip mixing mediums and paint straight to a scrap board instead. That took about twenty minutes out of my afternoon. Don't skip checking the prime coat before you bring materials home. Gesso needs at least two thin coats. Sand lightly between. Rough tooth helps paint grip. Smooth surfaces peel later if you're applying wet layers thick enough.

Paints Student-grade works for sketches and studies. Artist-grade pigments are what hold up over time and layer without cracking. I switched entirely to artist-grade for everything past a quick thumbnail after a few paintings started delaminating on cheap tubes. You don't need every color. A limited palette of cadmium red, cadmium yellow, ultramarine blue, titanium white, and a touch of phthalo blue gets you most mixes. Keep a couple warm and cool transparents like alizarin crimson and viridian if you plan color work.

Brushes Synthetic filaments handle acrylic's fast dry time better than natural hair. Natural bristles soak up water and sag under thicker paint. Flat, filbert, and round in small, medium, and large sizes cover 90% of what you do. Cheap brushes shed. Spend money where it counts and replace the ones that won't hold a point. Mediums & Additives

Gloss medium extends paint and slows drying without weakening the film. Matte medium reduces sheen and dries slightly faster. Gel medium adds body for impasto without breaking the binder ratio. I learned this the hard way when I thinned with just water for months and ended up with a chalky finish that flaked at the edges on a landscape I'd worked on for three weeks. Water & Cleaning Two containers. One for rinsing, one for clean water. I've never trusted the one-bowl method. Dirty water ruins brush control within minutes and makes colors muddy without you noticing until you step back.

Palette knives beat washing brushes mid-session when you're switching from dark to light. Scrap clean, reload. Saves three minutes per color change and keeps your palette organized. Protection & Workspace Acrylic cracks into everything. Nitrile gloves, an old shirt, and a drop cloth or newspaper. The smell isn't terrible since acrylic is water-based, but if you use solvent-based varnishes or mediums later, ventilation matters.

Work in a space where the painting won't get bumped. Dry time is short, but the film stays tacky longer than people think. A drafty room speeds things up but can cause uneven drying and crinkle marks if you aren't careful. Support Tools Easel, palette, rag or paper towels, jar lid for water, palette knife, references. Those are the basics. A spray bottle for keeping workable time matters more than most beginners expect. Mist the palette and the painting surface lightly if you need an extra ten to fifteen minutes on a layer.

Sealing & Storage Wait at least 48 hours before varnishing. Breathability matters. Use a removable varnish so you can redo the finish later without stripping the paint. Isopropyl alcohol or a dedicated acrylic cleaner works for cleaning brushes if you forgot soap nearby. Common Pitfalls to Watch For

Adding too much water weakens the acrylic binder. The paint might look fine wet, then turn cloudy and crack as it cures. Follow the 60% rule: no more than 60% water to paint by volume unless you're using a medium specifically designed for thinning. Dry-to-dry layering takes patience. Acrylic dries fast, which means you can't rework a mistake once it sets. If you need corrections, keep the top layer wet or sand it back after it cures. I lost a whole underpainting once because I tried to glaze over a dry layer without letting it fully cross-link. Took four layers to cover the bloom. Oil and acrylic don't mix reliably in the long term. If you ever want to paint over acrylic with oil, seal the acrylic first. Otherwise you'll get adhesion failure within a year or two.

Quick Reference Summary Surface: primed, acid-free, two-coat gesso with light sanding. Paints: artist-grade for final work, limited palette is enough. Brushes: synthetic flats, filberts, rounds in three sizes. Mediums: gloss, matte, gel for different effects. Water: two jars. Workspace: protected, ventilated, stable. Varnish: after 48 hours minimum with removable finish. This checklist is what I use and what I'd hand to someone who asked me to walk them through the process from start to finish. It covers the essentials without filling pages with filler. If you want a downloadable version formatted for the studio, I keep mine on a single sheet I reprint when it gets worn out.
