How much does epoxy cost per gallon?
Floor-coating epoxy runs about $30 to $150 per gallon depending on type: water-based is the cheapest, 100% solids costs the most, and polyurea or polyaspartic topcoats run about $150 per gallon. Enter your quantity and price below to see the budget with waste.
| Epoxy type | Angi (2026) | HomeGuide (2026) |
|---|---|---|
| Water-based | $30 – $50 | $40 – $100 |
| Solvent-based | $40 – $55 | $50 – $100 |
| 100% solids | $45 – $150 | $70 – $150 |
| Polyurea / polyaspartic | About $150 (This Old House 2026) | — |
Per gallon of floor coating material. Tabletop, casting, and art resin kits are priced per mixed gallon on the product listing.
Pricing a garage or basement floor?
Installed floor prices include prep and labor, which usually cost more than the material.

Avoid adding the same allowance twice
If the incoming quantity is already the recommended purchase amount from another calculator, set the waste buffer here to zero. For example, 5.35 gal at an illustrative $62 per mixed gallon is $331.70 of resin. A 2 gal mixed-yield kit means three kits and 6 gal purchased; compare that actual kit purchase with the continuous-volume material estimate. Tax, delivery, tools and labor are separate unless included in your price input.
What this calculator covers
- Translates planned quantity into a budget range you can actually compare against suppliers.
- Useful for quoting, procurement planning, and sanity-checking expensive pours before you order.
- Works best after the geometry is already solved on the right scenario page.
- Keeps waste factor, price normalization, and kit-size thinking in one place.
How to measure or set the inputs
- Start with the quantity you realistically expect to order, not the bare raw geometric minimum.
- Normalize your supplier price to a clear unit before comparing options.
- Use the unit converter first if one supplier lists liters and another lists gallons.
- Increase the waste setting if the project has irregular geometry, seepage risk, or overfill-and-sand steps.
Common mistakes that cost money
- Budgeting from raw volume instead of the buffered order quantity you will actually buy.
- Comparing resin prices without first converting them to the same unit basis.
- Ignoring how waste and overage can change the budget on high-volume pours.
Project checklist before you buy
- Confirm the mold or surface is sealed before mixing resin.
- Measure depth twice at the deepest point of the project.
- Add extra material for waste, seepage, and edge soak-in.
- Confirm the resin type matches the intended pour depth.
- Prepare cups, stir sticks, gloves, and a level work surface.
FAQ
Questions people ask before buying epoxy
Should I cost from the calculator output or from the product kit size I will actually buy?
The most practical answer is the kit size you will actually buy, because that is the real procurement decision.
Why does the budget change so much when the waste factor changes?
Because resin is a high-cost input. On larger pours, even a modest change in waste or safety margin can move the total cost much more than people expect.
Should I use this page before or after the geometry calculators?
After. This page is strongest when the quantity side is already believable and you are trying to convert that plan into a budget range.
