Epoxy flooring starter kit: what to buy first, in three budgets

A realistic epoxy flooring starter kit costs about $872–1,248 if you rent the floor grinder and dust extractor, about $2,772–3,648 if you also own the extractor, and about $16,405–19,166 if you buy everything, including a 22-inch dual-disc grinder and a trailer. The arithmetic is below, line by line. Materials, insurance and training come on top.

Below are the three budgets, what suppliers’ “starter kits” actually contain, how to judge one, and what to add as the work grows. The full equipment list, stage by stage, is in epoxy flooring equipment; to total your own setup including insurance and training, use the startup cost calculator.

Budget 1: rent first

You own what you use on every job and rent the expensive prep machines job by job.

This is the budget for your first jobs: the least cash at risk while you learn which work you’ll get. Rental shops usually bill diamond tooling separately; see the concrete grinder rental guide.

A first month on Budget 1

Say you book three garage jobs in your first month, each under 1,000 sq ft:

Tooling and materials come on top, and both belong in each job’s price, not in your startup budget.

Budget 2: buy the basics

Same owned kit, plus your own extractor, so you only rent the grinder.

The extractor comes first because, rented by the week, it pays back fastest: $1,900–2,400 ÷ $225 a week is about 8–11 weeks of rental. The rent vs buy guide works through the payback for each machine.

Size it to your tools before you buy. Under OSHA’s silica rules, a hand grinder’s dust collector needs at least 25 cfm of airflow per inch of wheel, so 7 × 25 = 175 cfm for the 7-inch edge grinder in this kit, and a floor grinder needs the airflow its maker recommends. Compact DE 110-class units are rated around 124 cfm; DE 120-class units, around 241 cfm, clear 175. If one extractor will serve your edge grinder too, price the larger class: $872 + $3,400 = $4,272 to $1,248 + $3,900 = $5,148 owned. Dust extractors and OSHA’s silica rules covers the filter requirements.

Budget 3: the full kit

Everything owned, for a business grinding most weeks.

Owning adds running costs: tools and equipment insurance for flooring installers runs about $41 a month (median), and a trailer needs a vehicle that can tow it.

Not in any of the budgets

• Materials. About $1–5 per sq ft of an installed epoxy floor; usually bought per job, or billed to the customer up front.
• Insurance. General liability for flooring installers runs about $77 a month (median).
• More insurance as you grow. Commercial auto runs about $208 a month and workers’ compensation about $144 a month (medians for flooring installers) once you put a vehicle to work for the business or hire help.
• Training, LLC fees and marketing. Covered in how to start an epoxy flooring business.
• Small items. Mixing buckets, tape, plastic, chip brushes, gloves, coveralls, a thermometer and hygrometer, a laser measure.

What suppliers’ “starter kits” contain

“Starter kit” means three different things depending on who’s selling. Examples from coating supply houses, at 2026 prices, not endorsements:

Application tool kits

• One Stop Epoxy full-flake tool kit, up to 400 sq ft, $279.99: two 18-inch rollers, a 1/8-inch notched squeegee, a heavy-duty roller frame, a cage mixer, a flat squeegee, spiked shoes, two 9-inch rollers and a frame, two chip brushes, a scraper and a painter’s pole.
• One Stop Epoxy metallic tool kit, 0–300 sq ft, $169.99: a 1/8-inch notched squeegee, two 18-inch rollers, a trowel for metallic effects, a roller frame, a cage mixer, spiked shoes, two 9-inch rollers and chip brushes.
• Epoxy Plus installation tool kit, $199.95: three 18-inch 3/8-inch roller covers, a roller frame, a 4-inch roller frame and three covers, an 18-inch flat squeegee, a mixing paddle and two pairs of spiked shoes.

Material kits

Full-flake floor kits are sized by area. One Stop Epoxy’s run $899 for up to 400 sq ft and $1,299 for 401–600 sq ft, each with a 100%-solids self-leveling epoxy base, full-broadcast vinyl flake and a polyaspartic clear topcoat; primer, moisture barrier, crack repair, anti-slip additive and tool kits are add-ons. That’s $899 ÷ 400 = $2.25 per sq ft on a full 400 sq ft floor. The supplies guide covers buying materials by the system instead.

Grinder and vacuum packages

• XPS Concrete Genie surface prep package, $11,999: a Concrete Genie floor grinder ($7,995 on its own), a Tromb 400L dust vacuum ($3,399), a microfiber squeegee kit, a Mohs hardness kit, 16- and 30-grit medium-bond trapezoid segments and PCD wheels. XPS sells it as a starter package.
• One Stop Epoxy Grizzly surface prep package, $12,995: a grinder, a vacuum and three sets of nine diamonds in soft, medium and hard bonds; in-store pickup, with shipping extra.

For comparison, the grinder, one tooling set and an extractor priced separately above add up to $8,488 + $195 + $1,900 = $10,583 to $8,488 + $530 + $3,900 = $12,918. The packages bundle different machines, so compare specifications, not just totals.

How to judge a kit

• Does it fit the system you'll install? Flake, metallic and polyaspartic jobs use different squeegees and rollers.
• Is it sized for your floors? Kits are labeled by square footage; one kit per job, or reusable tools?
• Grinder specs. Width, weight, voltage and amperage, and the tooling attachment it takes.
• Extractor specs. Airflow and filter rating, against OSHA's silica requirements; see dust extractors and OSHA's silica rules.
• Tooling. Which bonds and grits, and are they right for your local concrete?
• What's missing. Moisture tests, PPE, buckets, tape and solvent are rarely included.
• Support. Who services the machine, and how fast can you get parts?

Skip home-center garage kits for customer work. Do-it-yourself epoxy paints are often water-based, and some are light-duty latex paint with a little epoxy resin added: not the 100%-solids systems with data sheets your warranty will rest on.

What to add later

• Your own floor grinder, once you grind most weeks; the rent-vs-buy calculator shows when.
• A second tooling set in a different bond, and PCDs if you remove old coatings.
• A trailer when rental pickups start costing you jobs.
• A planetary grinder or shot blaster only when you’re bidding floors that need them.
• Extra spiked shoes, squeegees and roller frames as the crew grows.
