Professional Grade DIY Garage Floor Epoxy That Gives You Time to Work
One Stop Epoxy DIY Garage Floor Epoxy is a true two component, water based amine adduct epoxy made for homeowners, painters, and handymen who want a serious garage floor coating without moving into the faster application pace of a 100% solids contractor system. Each kit produces one full gallon of mixed coating, covers up to 200 square feet per coat, and provides a 1 to 2 hour pot life at 77 degrees Fahrenheit. The coating is self priming on properly prepared bare concrete and compatible existing coatings, comes in Light Gray or Tan, and can be installed as a solid color floor or finished with decorative vinyl flakes and a compatible urethane topcoat. Two coats are recommended over bare concrete for the most consistent color, sheen, and finished film build.
Quick answer: This is the middle ground between a convenience first retail coating and a higher build 100% solids professional system. It gives DIY installers published coverage, a manageable pot life, manufacturer approved preparation options, and direct technical support from people who work with epoxy floors every day.

Compare the Numbers, Not the Box
Garage floor products sold through retail stores vary widely. Some are one component coatings, some are two component epoxies, and others use different resin chemistry. The fairest way to compare any DIY garage floor kit is to look past the front of the package and check the coating type, solids by volume, coverage per coat, dry film thickness, pot life, surface preparation requirements, and available technical support.
| What to Compare |
One Stop Epoxy DIY Coating |
Why It Matters |
| Coating chemistry |
Two component water based amine adduct epoxy |
Part A and Part B chemically crosslink to form the cured coating. |
| Solids by volume |
55.32% plus or minus 2% |
Solids by volume helps show how much wet coating remains after water leaves during cure. |
| Published film build |
5.3 mils wet and approximately 3 mils dry per coat |
Two properly applied coats build approximately 6 mils of total dry film. |
| Kit size and coverage |
1 mixed gallon, up to 200 square feet per coat |
Honest per coat coverage makes it easier to calculate the full project before ordering. |
| Pot life |
Approximately 1 to 2 hours at 77 degrees Fahrenheit |
A longer application window gives a DIY installer time to cut in, roll, and add optional flakes. |
| Technical support |
Direct support from experienced epoxy installers |
You can ask about preparation, quantities, flakes, topcoats, and application before starting. |
Why We Are Proud of This DIY Epoxy
This product does not rely on an unprovable claim that it is a certain number of times stronger than every garage floor coating sold in a home improvement store. Its value is in the published numbers and the way the product is designed to be used. You receive separate Part A and Part B containers, one full gallon of mixed material, a published dry film thickness, clear preparation requirements, and enough pot life for a careful installer to work at a controlled pace.
It also gives customers room to choose how far they want to take the floor. Use the coating by itself for a clean solid color garage floor, add a light decorative flake broadcast, or finish the final coat with vinyl flakes and a compatible water based urethane for additional scratch resistance, wear resistance, and easier cleaning.
Important product position: This is our most approachable garage floor epoxy for serious DIY installers. Customers who want the higher film build of a 100% solids system should review our 100% Solids Epoxy Resin or complete Epoxy Flooring Systems.

How Much DIY Garage Floor Epoxy Do You Need?
One mixed gallon covers up to 200 square feet per coat. Two coats are recommended over bare concrete. Calculate each coat separately and order complete kits for both coats. Do not divide one kit between two coats. Roller covers, brushes, mixing containers, and normal application loss retain material, so splitting a kit will not provide dependable coverage. Porous, rough, or uneven concrete may also use more material.
| Measured Floor Area |
Kits for Two Coats on Bare Concrete |
| Up to 200 square feet |
2 kits |
| 201 to 400 square feet |
4 kits |
| 401 to 600 square feet |
6 kits |
Quantity formula for bare concrete: Allow one complete kit for each coat for every 200 square feet, or portion of 200 square feet. For example, a floor measuring 201 to 400 square feet requires two full kits for the first coat and two full kits for the second coat. Do not assume that every one car or two car garage is the same size. Measure the actual concrete floor before ordering.
Choose the Garage Floor You Want to Build
Solid Color DIY Garage Floor
Apply the coating in Light Gray or Tan without flakes for a clean semi gloss floor. Two coats are recommended over bare concrete. This is the simplest system and requires the fewest materials.
Decorative Flake Garage Floor
Add vinyl flakes to the final epoxy coat for added color and texture. A compatible clear topcoat is recommended for better cleanability and additional wear resistance.
Epoxy, Flakes, and Urethane Topcoat
Finish a decorative flake floor with One Stop WB Urethane in gloss or satin. The urethane adds scratch resistance, wear resistance, and easier maintenance. A heavy or full flake broadcast must be sealed with a compatible clear topcoat.
When This DIY Epoxy Is Not the Right Product
This coating is intended for interior concrete floors. It is not recommended for driveways, uncovered patios, exterior walkways, immersion service, corrosive chemical environments, areas exposed to intense heat, below grade substrates, or concrete with unresolved moisture problems. Prolonged direct sunlight can cause epoxy to fade, chalk, or yellow.
For commercial floor builds, full broadcast systems, metallic floors, higher film build, or projects that require a primer, moisture vapor barrier, 100% solids body coat, and high performance topcoat, shop our complete Epoxy Flooring Systems.
Frequently Asked Questions
Is this real epoxy or epoxy paint?
It is a true two component, water based amine adduct epoxy. Part A and Part B chemically crosslink during cure. It is easier to roll and clean up than a 100% solids coating, but it is not a one component floor paint.
Is this better than every big box garage floor kit?
Big box garage floor products use different chemistries and specifications, so we do not make a blanket claim that every product is the same or that this coating is a certain number of times stronger. We recommend comparing published solids by volume, dry film build, coverage per coat, pot life, preparation requirements, cure schedule, and technical support. This product publishes those numbers so you know what you are buying.
What does 55% solids by volume mean?
Solids by volume indicates how much of the wet coating remains as cured film after water leaves during the drying and curing process. This product is 55.32% solids by volume, plus or minus 2%, and produces approximately 3 mils of dry film per properly applied coat.
Is one coat enough on bare concrete?
Two coats are recommended on bare concrete for the best color and gloss uniformity. The second coat also brings the total dry film build to approximately 6 mils when both coats are applied at the listed thickness.
Do I need to grind the garage floor?
Not always. This product allows manufacturer approved acid etching for suitable bare concrete. Sealed, contaminated, damaged, or previously coated floors may require a different preparation method, and previously painted floors must not be acid etched. Review the complete preparation requirements on the product page before starting.
Can this epoxy go over an existing painted floor?
Potentially, when the existing coating is compatible and remains firmly bonded. Loose, peeling, or failing coatings must be removed rather than covered. Review the complete painted floor preparation requirements on the product page before ordering or starting the project.
How many epoxy kits do I need?
Each kit makes one mixed gallon and covers up to 200 square feet per coat. Multiply the floor size by the number of coats, divide by 200, and round up. A 400 square foot bare concrete garage normally requires four kits for the recommended two coat application.
Can I add decorative flakes?
Yes. Decorative vinyl flakes can be added to the final epoxy coat for color and texture. Shop our vinyl flake colors to choose a blend.
Do I need a clear topcoat?
A clear topcoat is optional over a solid color floor or light decorative flake application, but it adds scratch resistance, wear resistance, and easier cleaning. A heavy or full flake broadcast must be sealed with a compatible clear topcoat. One Stop WB Urethane is available in gloss and satin.
Can I use this DIY garage floor epoxy outdoors?
No. This coating is for interior use only. Exterior sunlight can cause epoxy to fade, chalk, or yellow.
Where can I find the complete preparation and installation instructions?
The complete surface preparation, mixing, induction, application, recoat, cure, and safety instructions are provided on the DIY Garage Floor Epoxy product page and in the current TDS and SDS sheets. Review those instructions before beginning the project.
What is the difference between this product and 100% solids epoxy?
This DIY coating is water based, approximately 55% solids by volume, and offers a longer pot life and soap and water clean up before cure. A 100% solids epoxy retains nearly all of its wet film thickness and is used when a higher build professional system is required. The DIY coating is the more approachable choice for a careful homeowner, painter, or handyman. The 100% solids lineup is intended for installers ready to manage a thicker material and a more demanding system build.
