The best epoxy flooring choice per square foot depends on the coating’s stated coverage, the concrete’s condition, and the finish you need. ArmorPoxy is best for a complete 300-square-foot DIY garage kit; Simiron is better for projects that need a high-build self-leveling coating; and Rust-Oleum is suited to a one-car garage. Gorilla lists coverage up to 550 square feet, while Everflow is an industrial-grade option without a stated coverage figure in the product details.
| Product | Stated Coverage | Best For |
|---|---|---|
| ArmorPoxy 17-Piece Kit | 300 sq. ft. | Complete DIY garage kit |
| Simiron 1100SL | 200–350 sq. ft. per 3 gallons | Self-leveling, high-build coating |
| Rust-Oleum EpoxyShield | One-car kit; exact area not specified | Sound concrete garage floors |
| Everflow MPC Clear Epoxy | Not stated | Commercial or industrial applications |
| Gorilla Garage Floor Kit | Up to 550 sq. ft. | Larger garage floors |
ArmorPoxy 300-Square-Foot Garage Kit
Best for: Homeowners who want a kit with application accessories and decorative flakes for a garage or workshop. ArmorPoxy specifies coverage for 300 square feet and describes the coating as 100% solids epoxy.
The 17-piece kit includes etching solution, decorative flake mix, a non-slip additive, a roller, and a squeegee. The manufacturer also describes a three-layer system intended to resist chemicals and hot-tire pickup, with a textured finish for traction.
Limitation: The stated coverage is 300 square feet, so measure the floor before choosing it. A larger floor may require more material.
Simiron 1100SL Self-Leveling Epoxy
Best for: Buyers who need a high-build, self-leveling coating and want a stated coverage range. Simiron lists 200 to 350 square feet per three-gallon kit, depending on concrete porosity and desired coating thickness.
This two-component, 100% solids coating is mixed at a 2:1 base-to-activator ratio, then poured and spread. Product details describe it for residential, industrial, and commercial floors, as well as countertops. The coating is solvent-free and is described as having adhesion, abrasion, impact, and chemical resistance.
Limitation: Coverage varies substantially with porosity and thickness. The instructions also say to pour out the mixed product rather than leave excess in the bucket.
Rust-Oleum EpoxyShield One-Car Kit
Best for: Owners of a one-car garage with concrete in good, sound condition who want a gloss finish with decorative chips. This is a water-based, two-part epoxy coating, and the kit includes coating, chips, and concrete etch.
Its listed use times make it easier to plan access after application: light foot traffic is listed at 12 to 16 hours, normal use at 24 to 48 hours, and vehicle traffic at three days.
Limitation: The product is specified for concrete in good, sound condition. The supplied details identify it as a one-car kit but do not provide an exact square-foot coverage figure, so check the package details against your measured area.
Everflow MPC Clear Epoxy Floor Kit
Best for: Buyers considering a clear, high-build epoxy for residential, commercial, or industrial spaces. Everflow describes its coating as self-leveling and industrial grade, with resistance to wear, acids, and yellowing over time.
The three-gallon kit is presented as a durable coating option for varied settings. Its clear finish may suit a project where the coating itself, rather than a gray color, is preferred.
Limitation: The supplied product details do not state square-foot coverage. Confirm the manufacturer’s coverage information and required coat thickness before estimating material needs.
Gorilla Epoxy Kit With Up To 550-Square-Foot Coverage
Best for: Buyers covering a larger garage floor who want one coat and a high-gloss finish. Gorilla lists coverage up to 550 square feet and describes the kit as a two-part, 100% solids epoxy with two gallons of material.
The product is described as resistant to chemicals, abrasion, salt, oil, gas, and hot-tire peel-up. Its listed uses include garages, basements, and workshops. The product details also characterize the finish as low-VOC and crack- and peel-resistant.
Limitation: Coverage is listed as “up to” 550 square feet, not a guaranteed amount for every floor. Confirm the area and application requirements before relying on maximum coverage.
Buying Guide: How To Compare Epoxy Flooring Per Square Foot
How do you estimate the material needed?
Measure the floor’s length and width in feet, then multiply them to get square footage. Compare that number with the product’s stated coverage. For an irregular floor, divide it into rectangles, calculate each area, and add them together. Treat “up to” coverage as a maximum, not a promise.
Coverage can depend on concrete porosity and the thickness you want. Simiron explicitly gives a 200-to-350-square-foot range per three gallons for those reasons. Products without a stated coverage figure should not be compared by kit size alone.
What should you check about the concrete?
Check the product’s surface requirements before purchasing. Rust-Oleum specifies concrete in good, sound condition. ArmorPoxy includes etching solution, while Rust-Oleum includes concrete etch. Follow the product instructions for preparation; coating coverage does not tell you whether a floor is suitable or ready.
Which finish and performance details matter?
Choose based on the intended space and the features stated for the coating. Decorative flakes are included with ArmorPoxy and Rust-Oleum. Simiron and Everflow are described as self-leveling, while Gorilla emphasizes a high-gloss finish and chemical and abrasion resistance. For areas that may get wet, compare traction-related details: ArmorPoxy lists a non-slip additive and textured finish.
How should cure time affect your choice?
Plan around the period when the floor must remain unused. Rust-Oleum lists separate wait times for foot traffic, normal use, and vehicles. The supplied details for the other products do not provide comparable cure-time figures, so check their instructions before scheduling a project.
Frequently Asked Questions
How much epoxy flooring do I need per square foot?
Divide the floor’s measured square footage by the product’s stated coverage per kit. Use the product’s coverage range and application instructions rather than assuming all epoxy kits cover the same area.
Why does epoxy coverage vary?
Concrete porosity and desired coating thickness can change how much material a floor needs. Simiron specifically identifies both as factors affecting its coverage range.
Can one garage kit cover any garage?
No. Kits have different stated coverage, and garage sizes vary. Compare your measured floor area with the specific kit’s coverage before buying.
When can a coated garage floor be used for vehicles?
Follow the product’s cure instructions. Rust-Oleum lists three days before vehicle traffic; the provided details for the other kits do not specify an equivalent time.
Does a higher listed coverage mean a lower cost per square foot?
Not by itself. Coverage is only one comparison point. Also consider the coating type, included preparation materials, finish, stated performance features, and whether the product’s coverage suits your floor conditions.
