Liquitex Basics vs Heavy Body 24 Set: A Procurement Manager's FAQ on Cost, Safety, and Brush Cleaning

I run purchasing for a small art college—about 20 studio classrooms and 450 students. I've managed a $60,000 annual art supply budget for seven years, and I've tracked every order in our procurement spreadsheet. When I first started buying acrylics, I assumed the lowest cost per set was the only number that mattered. In fall 2023, after one classroom switched to Liquitex Heavy Body, the paint usage per student dropped noticeably—even though the tubes cost more upfront. That changed how I evaluate every acrylic order.

Here are the questions our instructors and retail buyers ask most often.

Is the Liquitex Basics Acrylic Starter Box worth buying for a class or a store?

Short answer: yes, but treat it as a trial kit, not the main inventory. The Liquitex Basics Acrylic Starter Box is a low-cost way for a beginner to test the brand and the medium. I want to say it's around $22–$32 depending on the retailer, but don't quote me—prices move. What matters is that it gives a small set of colors in a compact box, which works for weekend workshops and outreach programs. Once a painter moves to larger canvases, the Basics line has a lower pigment load than Liquitex Heavy Body, so students use more paint per square foot. That eats into a supply budget fast. If you're a retailer, keep a few starter boxes near the register, but pair them with the 24-set option for serious painters.

What's the real difference between Liquitex Basics and the Liquitex Heavy Body Acrylic Set of 24?

Let me talk about this like a procurement nerd, because that's what I am. The Liquitex Heavy Body Acrylic Set of 24 costs more upfront—roughly $180 to $220 in January 2025 for 24 22ml tubes—but the paint is significantly more concentrated. In our studio tests, students using Heavy Body often skip the second coat, so the cost per finished canvas can actually be lower than with Basics. The 24-color range covers the core palette our painting teachers expect: Titanium White, Carbon Black, Phthalo Blue, Quinacridone Magenta, and similar pigments. The heavier viscosity also works for palette knife and impasto techniques. One thing I've learned: don't try to match a Pantone brand color with a tube of acrylic. Pantone is a printing ink system; pigment index numbers on the tube are what help you mix consistently. For a serious color-theory semester, I'd order Heavy Body. For a kids' art camp, the starter box is enough.

How to clean acrylic paint brushes without blowing your brush budget

Here's the lesson I learned the hard way: don't let brushes sit in water. In my first year, I made the rookie mistake of filling jars with water and thinking that was 'soaking.' It wasn't. The paint dried around the ferrule, the bristles splayed out, and our brush replacement requests tripled. The process that actually works: rinse the brush in lukewarm water right after painting, work in a mild soap, press the paint out from ferrule to tip, rinse, reshape, and lay the brush flat to dry. Never leave it standing bristle-up—water gets into the ferrule. And don't use hot water; it sets acrylic. If the paint is already dry, isopropyl alcohol can help, but that's last-resort territory. We posted this routine on every studio sink and our brush spend dropped by about 25%.

Are Liquitex paints safe for classrooms? What does 'cadmium-free' mean?

Safety is an area where I've learned to read the fine print. Cadmium is a heavy metal, and some traditional paint colors were made with cadmium pigments. Liquitex has been expanding its cadmium-free line, so many colors use alternative pigments and avoid that heavy-metal concern. That's good for K-12 classrooms. But 'cadmium-free' doesn't automatically mean 'non-toxic.' You still need to check the label for the AP Seal and ASTM D4236 compliance, and your school or district may require the current Safety Data Sheet before any paint enters a classroom. Honestly, I'm not sure what's in every color on my list—that's exactly why I ask for SDS. A purchase order in our system can't go through without one.

How much Liquitex paint do you actually need? And what is a crcl calculator for?

This is where I geek out. When teachers ask for 'enough paint,' I stop thinking in tubes and think in square inches. For a rectangular canvas, multiply length by width. For a round canvas, use a circle calculator. Omni Calculator has a free one—the crcl calculator if you use that search abbreviation—where you enter the radius and get the area. A 24-inch round canvas, for example, is about 452 square inches. At a wet film thickness of 2 mils, you need roughly 15 ml of paint to cover it once. That's most of one 22ml tube. Heavy body paint doesn't spread as far as a thinned paint, and a textured surface will eat more, so treat this as a planning estimate, not gospel. I've used this formula in our budget spreadsheet and it's saved us from over-ordering more than once.

What hidden costs do people miss when comparing Liquitex acrylic sets?

The biggest one is packaging and storage. The Heavy Body 24 set comes in a sturdy box that protects the tubes and stacks well on a shelf. The Basics starter box is smaller and easy to lose, especially in a shared classroom. Another hidden cost is color mixing. A student with only five colors will try to mix Sap Green, fail, and ask for more tubes. A larger set reduces those one-off orders. Also check the cost per ml before judging a deal. A $25 starter box with six 22ml tubes is around $0.19/ml. A $200 Heavy Body 24 set is about $0.38/ml. But because Heavy Body covers better, the cost per finished painting is often lower. There's no single perfect choice; it depends on whether you prioritize cash outlay or long-term cost per use.

Should schools and retailers buy Liquitex in bulk?

It depends on your storage and your student population. For a retailer, open-stock tubes are usually more profitable than sets because painters return to replace one color—usually Titanium White. For a school, sets are easier to issue to a class and keep the color range consistent. When I order for our campus, I always get quotes from three suppliers and factor in shipping weight. Once I almost ordered a pallet of paint because the unit price was lower, then realized freight made it more expensive than buying from a local distributor. The lesson: compare delivered cost, not list price. If you have the space, a 24-set is a solid starting point. If you're short on space, order individual tubes in the colors that run out fastest.
