Key takeaways
- Indiana licenses plumbers and no other construction contractors; cities and counties license the rest, and Indianapolis requires a general contractor license with a $10,000 bond.
- Indiana caps floor coatings at 250 grams of VOC per liter statewide, and the rule covers the people who apply coatings as well as those who sell them.
- Home improvement contracts over $150 must be in writing, with the price, the work and materials, the start and finish dates and your signature.
- An LLC costs $95 to file online, plus a business entity report every two years for $31 online.
- Owners with no employees file a $20 workers' comp exemption certificate every year; general contractors ask for a copy before they hire you.
- Normal daily highs stay below 50°F from November through March in Fort Wayne and South Bend, and from December through February in Indianapolis and Evansville.
Indiana leaves most of a coating contractor’s paperwork to its cities. The state licenses plumbers and no other construction contractors, so the license that matters is local, starting with Indianapolis, which licenses general contractors. Two state rules still reach every job: a cap on the solvent content of floor coatings, and a written-contract requirement on home improvement work over $150. The other constraint is the winter, which takes unheated garages off the schedule for three to five months depending on where you work.
Do you need a license for epoxy floors in Indiana?
Not from the state. Plumbers are the only construction contractors Indiana licenses. Licensing everyone else, including general, flooring and coating contractors, is left to cities and counties, so the rules change from one city or county to the next. Before you quote in a new place, ask its building department whether it licenses or registers contractors and whether the job needs a permit.
Indianapolis: a general contractor license
Indianapolis licenses contractors through its Department of Business and Neighborhood Services, for work in the consolidated city: all of Marion County except Lawrence, Beech Grove, Speedway and Southport. The city code requires anyone doing “any construction” work there to be a listed contractor, so if you coat floors in Indianapolis, plan on the general contractor license and confirm your scope with the licensing office. What it takes:
- A $10,000 surety bond naming the city or an unknown third party as obligee.
- General liability insurance of at least $500,000 per occurrence, with the city named as an additional insured.
- Workers’ comp for anyone you employ in Marion County. Owners of sole proprietorships, partnerships and LLCs without employees can sign the waiver on the application or file the state exemption certificate instead.
- The fee: $124 for a new license applied for in 2026, because the fee is prorated over the two-year term, and $247 to renew. Every license expires on December 31 of an even-numbered year, and new licensees attend an orientation class within 60 days.
Home improvement contracts over $150 go in writing
Indiana law requires home improvement contracts over $150 to be in writing, which covers every garage floor you’ll sell. The state’s checklist for homeowners asks for the price, the payment schedule, a detailed description of the work and materials (including colors and brand names), estimated start and completion dates, your name and address, a contact for problems, and your signature. The attorney general also tells homeowners never to pay more than a third up front. That’s advice, not law, but Indiana customers hear it, so build your deposit around it. Epoxy flooring contract covers the rest of a good contract.
Indiana’s VOC limit on floor coatings
Indiana has its own limits on the solvent content of architectural and industrial maintenance coatings, and they apply statewide to anyone who sells or applies those coatings.
- Floor coatings: 250 grams of VOC per liter. The national limit is 400 g/L, so a product that meets the national rule can still be over the limit on an Indiana job.
- Industrial maintenance coatings: 340 g/L, for products labeled for industrial or professional use only.
- No thinning past the limit on the job, and containers stay closed when you’re not using them.
- Containers of one liter or less are exempt, so the rule bites on the kits, not the touch-up cans.
A 100% solids epoxy and a high-solids polyaspartic are far under 250 g/L. Solvent-based sealers and some urethane topcoats are where to look; check the VOC figure on the data sheet before you stock a product.
Setting up the business: LLC, entity report and workers’ comp
Forming an LLC costs $95 online through INBiz ($75 for the filing plus a $20 online access fee) or $100 on paper. Every two years, the LLC files a business entity report: $31 online or $50 on paper.
Workers’ comp is required for every Indiana employer, bought from a private insurer. Owners in the construction trades who don’t carry it on themselves prove their status with a certificate of exemption: a $20 application through the Department of Revenue ($5) and the Worker’s Compensation Board ($15), paid by money order or certified check. It isn’t valid until the Board stamps it, takes effect seven business days later and lasts one year. General contractors ask for a copy, because the certificate holds them harmless if you’re hurt on their job.
Safety in Indiana is enforced by the state. Indiana runs its own OSHA plan, which covers private employers, including the silica rules that apply when you grind concrete. A shroud and a HEPA dust extractor belong in the starting kit; see dust extractors and silica rules.
Cold winters, humid late summers: installing in Indiana
A typical high-solids floor epoxy needs air, slab and material at 50°F or warmer, relative humidity no higher than 85%, and a slab at least 5°F warmer than the dew point. Here’s what Indiana’s cities give you:
| City | Normal January high | Normal January low | Normal highs below 50°F | Average morning humidity, Aug–Sept |
|---|---|---|---|---|
| Indianapolis | 36.1°F | 20.9°F | December–February | 86% |
| Fort Wayne | 32.6°F | 18.4°F | November–March | 87% |
| South Bend | 31.2°F | 17.0°F | November–March | 86% |
| Evansville | 41.7°F | 25.5°F | December–February | 88–89% |
Morning readings are taken at 7 a.m. Eastern time, and at 6 a.m. in Evansville, which is on Central time.
- Plan the season by region. Unheated garages are realistic from about April through October across the state. Fort Wayne and South Bend lose November and March as well as midwinter.
- Cold slows the cure. A typical floor epoxy takes foot traffic after 48 hours at 50°F instead of 24 at 77°F, needs 24 hours before the next coat instead of 8, and fully cures in 10 days instead of 7. Quote the longer times for April and October jobs.
- Winter work needs heat or a cold-rated product. A heated garage can be coated if the slab itself is warm enough, not just the air. Some polyaspartics are rated down to a 40°F surface, though they work best between 60°F and 90°F.
- Late-summer mornings are wet. Average morning humidity reaches 86–89% in August and September. At 75°F and 85% humidity, the dew point is about 70°F, so the slab has to be as warm as the air before you open a kit. Coat later in the morning, and read the slab, not the forecast.
Where the work is in Indiana
Indiana had 6,973,333 residents on July 1, 2025, the 17th-largest state, and added 38,579 people that year, including a net 12,197 who moved in from other states. Most of the growth is around Indianapolis: the Indianapolis–Carmel–Greenwood metro reached 2,205,695 people after adding 22,271 in a year, 1.0%, one of the 20 largest gains among US metros. Fort Wayne (466,258) grew more slowly, and South Bend–Mishawaka held flat.
Two corners of the state belong to bigger metros next door. Lake and Porter counties are part of metro Chicago, and the southeast corner is part of metro Cincinnati and Louisville, which is worth knowing when you choose a supplier or a class.
Where to take an epoxy class in and near Indiana
One supplier class comes to Indiana; the rest are a short drive away:
| Class | Where | Length | Price | Price per day |
|---|---|---|---|---|
| ResinForce | Indianapolis (no new date yet) and Cincinnati, OH | 2 days | $500 ($400 each for 2+) | $250 |
| Epoxy Depot Intro to Epoxy | Joliet (Chicago), IL | 3 days | $750 | $250 |
| The Concrete Protector | Lima, OH | 2 days | $499 deposit, returned as store credit | — |
| Deco-Crete Supply intro | Columbus, OH | 2 days | $849.99 | about $425 ($849.99 ÷ 2) |
ResinForce’s travelling class held its last Indianapolis session in September; its next date nearby is Cincinnati in November, and it works through prep, metallic, flake, quartz and grind-and-seal systems. From northwest Indiana, Epoxy Depot’s three-day intro outside Chicago is closest. From Fort Wayne, Lima is about the same drive as Indianapolis, and its deposit comes back as store credit, so the class is free for you and a guest if you buy its products.
Epoxy Business School classes in Indiana
Epoxy Business School hasn’t scheduled an Indiana class yet. Classes open state by state with partner trainers who install floors for a living, in the states where enough people ask for them. Before the two days on the slab, students complete The Epoxy Playbook: recorded installation training, with full installs you can replay, plus the business side of pricing, quoting and selling. It’s required before the hands-on class.
If you’re in Indiana, leave your number below and we’ll text you when a class is set. If you’ll also work in Illinois, Ohio, Michigan or Kentucky, each sets its own rules; see license requirements by state.
