Liquitex FAQ: Gel Medium, Freestyle Brush Set, and Is Acrylic Paint Toxic?

I'm a procurement manager for a 46-person educational art supply company. For the past six or seven years—maybe six, I'd have to check my start date—I've managed our paint and brush budget, which runs around $45,000 a year. I've documented every order in our procurement system. Here are the questions I actually answer about Liquitex for our school and retail clients.

Is Acrylic Paint Toxic?

Short answer: not if you use it the way it's meant to be used. But you can't treat every color the same. Most Liquitex colors carry the AP Seal from ACMI, which means they're safe for adult art use when used as intended. That's not the same as saying 'food safe' or 'skin safe for everyone.' Some pigments contain cobalt, manganese, or other metals that need a bit more care.

Per FTC guidelines (ftc.gov), safety and environmental claims have to be truthful and substantiated. That's why I look for the AP Seal, check the pigment code, and pay attention when a label says to avoid skin contact. Liquitex's professional lines are cadmium-free, which removes one of the old health worries, but the universal rule still applies: don't swallow paint, don't paint your face with it, and wash your hands afterward.

Does Liquitex Acrylic Gel Medium Actually Do Anything?

Gel medium is essentially acrylic binder without pigment. You can mix it into paint to change the body, use it as a collage adhesive, slow drying time, or build texture. From the outside, it looks like a trick to make expensive paint go further. The reality is more useful: it changes how the paint behaves on the surface.

For schools, the cost question is fair. A jar of Liquitex gel medium costs more than a generic student-grade medium. But I've seen the generic stuff cloud colors or change the finish, and I've seen finished pieces crack when someone thinned the medium with too much water. That creates a redo—and redo is the most expensive thing in an art room.

Are Liquitex Freestyle Brush Sets Worth It?

If you're buying for a high school class or a community studio, yes. I've compared the Liquitex Freestyle brush set against the cheap synthetic packs we used to order. The cheap brushes shed bristles in the first few washes. The ferrules loosen, and students spend more time picking hair out of paint than painting.

Freestyle brushes are still synthetic, which is right for acrylics, and they hold their shape reasonably well over a semester. You don't need the biggest set either. The smaller set with a flat, round, and detail brush covers most classroom projects. Test one, track how long it lasts, and compare that with the cheap option. If it lasts twice as long, the higher unit price is actually the value buy.

Do I Need a Sticker Printer for the Art Room?

This question sounds unrelated to Liquitex, but stick with me. A thermal sticker printer—one of those little label printers—has saved us from buying duplicate supplies. We label every gel medium jar, gesso bucket, and paint bottle with the date it was opened and the classroom that owns it.

In 2024, we pulled eleven half-used jars of the same gesso out of one school's storage. Nobody knew what was already open, so they kept ordering more. A sticker printer is around $100, and replacement labels are cheap. If you manage more than one classroom, it pays for itself in the first month.

Wait, Should I Get a Scrap Gold Calculator?

The only reason I mention this is that someone once asked me whether an art department should buy one to fund supplies. A scrap gold calculator helps you figure out the melt value of jewelry or metal scraps. If your program has a jewelry or metalwork component, and people donate old gold, then sure—it helps you price donations fairly. A teacher in our district used one to identify a box of old findings worth around $220, which was enough to buy two cases of Liquitex heavy body paint.

But if you're not handling scrap gold, pass. The better calculator for paint purchasing is something you can build yourself: total cost per usable hour. That's how I compare options. A $6 brush that fails in two weeks is more expensive than a $14 brush that lasts a semester. A scrap gold calculator tells you what metal is worth. It doesn't tell you what art supplies are worth to your teaching.

Why Does Liquitex Cost More Than Discount Acrylic?

Because you're paying for consistency and pigment load. In my first year of purchasing, I made the classic rookie mistake: I chose the cheapest acrylics because the budget was tight. We saved about $300 on that order and spent more later when students' work faded, peeled, or didn't mix the same way. I can't prove every problem was the paint, but I stopped making that call.

Liquitex professional paints aren't the cheapest, and I'm not saying everyone needs professional grade. There's a practical middle ground: use student-grade Liquitex for practice, professional grade for final work, and gel medium to extend it. That balance gets you quality without blowing the budget.

What's the Smartest Way to Budget Acrylic Supplies?

Don't compare unit prices. Compare cost per project or per student. I want to say we budget around $2,500 per classroom per semester for paint-related supplies, but don't quote me on that—it varies a lot by school and curriculum. The method matters more than the number.

Start with a full supply list, add 10% for waste, and include shipping. USPS lists First-Class Mail letters at $0.73 and large envelopes at $1.50 as of January 2025 (usps.com). A set of brushes or a couple of medium bottles can easily push you into a larger mail class, and that cost can quietly wreck a well-priced order. Verify current rates before you finalize a budget.

From the outside, procurement looks like picking the lowest quote. It isn't. It's about predicting which product will make it to the classroom and stay useful long enough to justify the invoice. That's the only calculation I run on every Liquitex order.
