Three choices set the number
Before any line item, three decisions decide most of your total. Everything else is detail around them.
Rent, used, or new grinding equipment
The widest swing on the page. A rented grinder and vacuum turns your biggest cash purchase into a per job cost. Buying new is the largest single thing most shops spend money on in year one. Used sits in between, and it is where most working shops actually started.
Whether you already own a truck
If a good vehicle is already in your driveway, you removed one of the two largest lines before you bought anything. If not, it is probably the largest.
How much operating cash you hold back
Almost every startup list ignores this. Which is exactly why it decides whether month four happens. It gets its own section below.
Anybody quoting you a tidy startup figure has silently picked all three for you. They almost certainly did not pick what you would. Make them yourself in the startup cost calculator.
What each category actually buys you
Grinding and surface prep
Planetary grinder, dust extractor, diamond tooling, hand grinder and edger, crack chase tools. This is the expensive end, and the last place to save money, because nearly every coating failure traces back to prep. Tooling is a consumable. Buy a spare set before your first job, not after it.
Mixing and application
Low speed mixer and paddles, squeegees, rollers, spike shoes, broadcast gear, moisture meter. Cheap next to the prep equipment and easy to underbuy. One set of hand tools for a two person day costs you a day.
Safety and compliance
Respirators and fit testing, a written silica exposure program, PPE, first aid. Small numbers with big consequences. The written program matters as much as the masks. Silica rules apply to anyone grinding concrete, and "we wear masks" is not a compliance plan.
Truck and trailer
If you are financing, budget the down payment here. The monthly payment belongs in your operating reserve instead. Racking and organization inside the trailer is not a luxury. A trailer you cannot find anything in costs you hours every week, and hours are your biggest cost.
Opening materials
Enough resin, topcoat and flake to run your first jobs without an emergency order, plus patch and consumables. Buying material job by job is how a new shop ends up paying rush freight on thin margins.
Business setup
Entity registration, licensing, general liability, workers compensation if you have employees, and an accountant to set the books up. Boring and unavoidable, and underbudgeted because none of it shows up on a job site. Get the chart of accounts right in month one and job costing works later. Get it wrong and you will be rebuilding your history.
Marketing
Website, branding, vehicle wrap, yard signs, sample boards, and an opening ad budget. The line new shops cut first and regret fastest. A fully loaded trailer with an empty calendar is the most expensive mistake available.
The line that is not on anyone’s list
Operating cash. Not equipment. Not insurance. Cash.
The problem is completely predictable. You coat a floor on the 3rd and invoice it. The homeowner pays on the 24th. A builder pays on day 45. Meanwhile your helper is paid on the 15th, insurance drafts on the 1st, the truck payment does not care, and you are buying material for the next job before you got paid for the last one.
That gap is normal and survivable, if it is funded. Unfunded, it is the most common way a new coating business with plenty of work on the board goes under. Busy and broke has nothing to do with whether your prices are right. It is a cash timing problem, and you solve it before you open or not at all.
The test. Add up everything that leaves your account in a month whether or not you coat a single floor. Loan payments, insurance, phone, software, fuel, and what you live on. Multiply by three.
If that number is not in your startup budget, you have not budgeted to start a business. You have budgeted to buy equipment.
Where new shops overspend
- A bigger truck than the work needs. The most common first year purchase people regret. It is visible, it feels like progress, and it loses value while the calendar is still thin.
- A shot blaster or sprayer rig in month one. Both are justified by a schedule you do not have yet. Buy capacity when the calendar proves you need it.
- Every color of flake made. Carry the colors you sell. Inventory you are not turning is cash sitting on a shelf.
- New where used does the same job. Trailer, racking, hand tools, mixing gear. A dented trailer coats exactly as well.
- Software that does not fit the trade. Generic field service tools handle a calendar well and leave materials and job margin to a spreadsheet. So you pay for software and still do the work by hand.
And the other side of it. Where new shops underspend, every time: dust extraction, insurance, marketing, and cash.
What the number means in floors
A startup total is an abstraction until you turn it into jobs. Jobs are the only unit that means anything on a job site.
Take your total. Divide by your net profit per job, which is what is left after material, crew and overhead, not the invoice total. Now you have the number of floors it takes to earn back what it cost to open. Divide that by jobs per month for a timeline.
Two honest caveats. It ignores your ongoing spending while you earn it back, so treat it as a floor and not a forecast. And it depends on your net profit per job being a real number instead of a hopeful one. Which means it depends on pricing properly from the first quote. The startup calculator runs this at the bottom.
One line on the list costs nothing

Common questions
What does it cost to start an epoxy floor business?
Three choices decide most of it. Whether you rent, buy used or buy new grinding equipment. Whether you already own a truck. How much cash you hold back. Those three move the figure more than every other line put together, which is why a single national number is not useful. Make each choice yourself in the startup cost calculator.
What is the biggest startup expense?
Usually the grinder and dust extraction, or the vehicle if you do not already have one. Those two dominate the equipment budget. But the biggest expense people fail to plan for is operating cash. That is the money covering payroll, insurance and material between finishing a floor and getting paid for it.
Can I start an epoxy business with no money?
Not with none, but with far less than most lists suggest. Rent your grinding equipment. Sub for an established shop while you build a customer base. Buy material job by job on deposits. Use a vehicle you already own. What you cannot skip is insurance, and enough cash to cover the gap between doing the work and getting paid.
Should I buy or rent a concrete grinder?
Rent until the machine would have paid for itself, then buy. Renting turns a big cash purchase into a per job cost while your close rate is still unknown, which is the right trade in year one. The costs are real though. It eats margin on every floor, your schedule depends on what is available, and you cannot match tooling to the slabs in your market.
How long before a coating business pays back its startup cost?
Divide your total startup cost by your net profit per job. Net profit is what is left after material, crew and overhead, not the invoice total. That gives you a number of floors. Divide by jobs per month for a rough timeline. Treat it as a floor and not a forecast, because you keep spending while you earn it back.
Why there are no dollar figures in this guide. Equipment, insurance, licensing and vehicle costs vary too much by brand, condition, state and the week you buy. A published number would not be worth anything, and a confident wrong figure is worse than none.
The calculator uses clearly labeled placeholders you replace with real quotes you have been given. Nothing here is legal, tax or financial advice.
