Garage floor “epoxy” covers a wide range of products. Some are true two-part epoxies, some are one-part acrylic-epoxy paints, and some are hybrid chemistries sold next to epoxy on the same shelf. They differ a lot in how thick they go on, how long they take to cure, and how well they stand up to hot tires and road salt.
We didn’t test these products ourselves. This guide compares popular DIY options using the numbers the manufacturers publish (coverage, solids content, cure times and recoat windows) so you can choose based on your floor, your budget and how long you can keep the car out of the garage.

How we chose
We looked for products that are:
- Widely sold at Home Depot, Lowe’s and Amazon, so DIYers can actually buy them.
- Backed by a published technical data sheet (TDS) or instruction sheet with coverage and cure data.
- Made for residential garage floors, not industrial systems that need special equipment.
We left out products whose coverage or cure claims we couldn’t check against a manufacturer document.
1. Rust-Oleum RockSolid Polycuramine Garage Floor Kit — best overall DIY kit
Strictly speaking, RockSolid isn’t a pure epoxy. Rust-Oleum’s TDS describes the resin as a “proprietary blend of epoxy, urethane and polyurea” at 96% solids by volume with VOC under 1 g/L. High solids matter because most of what you roll on stays on the floor instead of evaporating, so you get a thicker film per coat.
Key specs (Rust-Oleum TDS RSD-10 and product page):
- Coverage: each pouch covers up to 200–250 sq ft. The 2.5-car kit (two pouches) covers up to 450–500 sq ft.
- Pot life: 45 minutes to 1 hour.
- Foot traffic in 8–10 hours, vehicle traffic in 24–36 hours.
- Application temperature: 40–90°F per Rust-Oleum’s product page. Home Depot’s listing gives 55°F as the optimal minimum.
- One-coat system with a 7-day recoat window without sanding.
- Kit includes burst pouch, foam roller, decorative chips and concrete etch.
Things to know: Mixed product cleans up with mineral spirits, not water. The short pot life means you should have a helper and a plan before you burst the pouch. “20x stronger than epoxy” is Rust-Oleum’s marketing claim and we haven’t verified it independently. It is also one of the more expensive DIY kits: Home Depot listed the 2.5-car kit at roughly $300–$330 when we checked.

2. Rust-Oleum EpoxyShield Garage Floor Kit — best budget two-part epoxy
EpoxyShield is the kit a lot of DIYers start with. It’s a two-component, water-based epoxy packed in a burst pouch (92.5 fl oz base plus 27.5 fl oz activator), and the kit also includes concrete etch and decorative chips.
Key specs (Rust-Oleum TDS ESH-39 and instruction sheet):
- Coverage: about 250 sq ft of smooth, bare concrete per 1-car kit. Rust-Oleum says to expect 125–200 sq ft on rough or porous concrete.
- Solids: 52.6–52.8% by volume. Recommended dry film is 3.0–3.5 mils per coat.
- Pot life: roughly 1–2 hours depending on temperature.
- Light foot traffic in 12–16 hours, normal foot traffic in 24–48 hours, full cure and vehicle traffic in 3 days.
- VOC under 50 g/L. Soap-and-water cleanup.
Things to know: Rust-Oleum states it is not intended for floors with moisture problems or for unsound existing coatings. With about half the solids of RockSolid, the film is thinner, so careful surface prep matters even more. A tint-base version can be tinted to 27 colors.

3. Seal-Krete Epoxy-Seal Pro — two-part alternative
Seal-Krete (a Rust-Oleum family brand) makes Epoxy-Seal Pro, a premium 2-part water-based epoxy available in clear and gray and tintable to 16 colors.
Key specs (Seal-Krete TDS):
- Coverage: up to 250 sq ft of smooth, bare concrete (an average 1-car garage). About 125–200 sq ft on broom-finished or porous concrete.
- Designed as a one-coat system. If a second coat is needed, apply it within 24 hours.
- Foot traffic in 24 hours, vehicle traffic in 72 hours.
- Apply when air, surface and material are between 50°F and 95°F, with relative humidity at or below 80%.
- Concrete must have cured at least 30 days. Concrete etch is included.
Things to know: Like EpoxyShield, it isn’t designed for slabs where moisture reaches the underside of the coating.

4. BEHR Premium Concrete & Garage Self-Priming 1-Part Epoxy (No. 900) — easiest to apply
A one-part “epoxy” is a ready-to-use, epoxy-modified water-based floor paint with nothing to mix and no pot life to race. Behr says No. 900 resists hot-tire pickup, automotive fluids and household chemicals, and it can be used indoors or outdoors.
Key specs (Behr product page):
- Coverage: 300–400 sq ft/gal on rough concrete, 400–500 on smooth.
- Dry to touch in 1 hour, recoat in 4–6 hours. Behr says not to apply more than 2 coats.
- Apply between 50°F and 90°F. Satin finish. GREENGUARD Gold certified.
- Not for vertical surfaces, areas with hydrostatic pressure, or forklift/industrial use.
Things to know: One-part products build a much thinner film than two-part kits. They suit lighter-duty floors, or buyers who care most about easy application. Behr also notes that coated floors can be slippery when wet and sells an anti-slip additive (No. 970).

5. Seal-Krete Epoxy-Seal (1-part) — interior/exterior option
Seal-Krete’s original Epoxy-Seal is a water-based acrylic-epoxy blend for garages, driveways, pool decks and patios.
Key specs (Seal-Krete label/TDS via Lowe’s):
- Coverage: 300–500 sq ft per gallon. Apply two thin coats, 4–6 hours apart, perpendicular to each other.
- Apply at 55–90°F. Concrete must be at least 30 days old and etched.
- Vehicle traffic: 5 days at 90°F, 7 days at 77°F, 10 days at 55°F.
- Seal-Krete reports ASTM D-4541 adhesion of 570 psi with 100% concrete failure on smooth, etched concrete. That is the manufacturer’s own test result.
Things to know: Plan on a long wait before you can park on it, especially in cool weather. It’s only rated for use over previous one-part water-based coatings.

Buying guide: what actually matters
1. One-part vs. two-part vs. hybrid
- One-part (epoxy-modified paint): easiest to apply, thinnest film, lowest cost. Fine for light use.
- Two-part water-based epoxy: a chemical cure gives better hardness and chemical resistance. You have to work within a pot life.
- High-solids / hybrid (polycuramine, polyaspartic): a thicker build and faster return to service. They cost more and the working window is shorter. See our epoxy vs. polyaspartic comparison.
2. Solids by volume
Solids are what’s left after the coating cures. Compare the two Rust-Oleum products: at the same wet thickness, a 96%-solids coating leaves far more film than a 53%-solids coating. Look for “solids by volume” on the TDS.
3. Coverage on your concrete
Manufacturers usually quote coverage for smooth, bare concrete. Broom-finished or porous slabs can cut it by 20–50% (EpoxyShield goes from 250 to 125–200 sq ft). Measure your floor and use our epoxy calculator, then add a margin.
4. Return-to-service time
How long can you live without the garage? Return-to-service ranges from 24 hours (RockSolid) to 3 days (two-part water-based) to as long as 10 days for one-part products in cool weather.
5. Moisture and prep
Every product above requires clean, sound, profiled concrete, and most fail on slabs with moisture coming up from below. Do a plastic-sheet moisture test first. Our step-by-step guide covers it.
FAQ
How many kits do I need for a 2-car garage? A typical 2-car garage is about 400–480 sq ft. At ~250 sq ft per 1-car EpoxyShield kit on smooth concrete you’d need two kits, and three if the concrete is rough. One RockSolid 2.5-car kit is rated for up to 450–500 sq ft.
Is garage floor epoxy UV-stable? Standard epoxies tend to amber in sunlight. If your garage door is often open, consider a UV-stable topcoat such as polyaspartic or polyurethane.
Can I put epoxy over old paint? Usually not over unsound or glossy coatings. Each manufacturer above lists specific limits, so check the TDS.
