Our Picks: Best One Part Epoxy Floor Paint reviews
1. KILZ 1-Part Epoxy: A Versatile Pick for Residential Concrete
KILZ is the most broadly specified option in this group. Its one-part epoxy acrylic formula is intended for properly prepared porous concrete, masonry, stone, and brick. The paint is slate gray with a satin finish, and the product is listed for interior and exterior horizontal surfaces.
Its stated uses include garage floors, basements, porches, driveways, and pool decks. The water-based formula can be applied with a roller or brush and cleaned up with soap and water. KILZ lists coverage of 300–400 square feet per gallon on smooth surfaces and 200–300 square feet on rough ones, so estimate using the lower range if your concrete is textured.
The product description says the coating resists hot tire pickup, scuffing, cracking, peeling, and fading. That makes it a practical choice for many residential areas with regular foot or vehicle use, though it is not intended for every concrete condition. KILZ says it is not for vertical surfaces, areas exposed to hydrostatic pressure, or forklift traffic, and specifies residential use.
Compared with the SHENGWEI options, KILZ provides more detail about suitable surfaces, finish, coverage by surface texture, and limitations. Its main trade-off is that the coverage estimate varies with the condition of the concrete, so one gallon may not cover as much on a rough floor.
Pros:
- Listed for both indoor and outdoor horizontal concrete surfaces
- Coverage guidance is provided for smooth and rough surfaces
- Water-based formula cleans up with soap and water
- Slate-gray satin finish and stated resistance to several common forms of wear
Cons:
- Not intended for vertical surfaces, hydrostatic pressure, or forklift traffic
- Coverage can drop on rough concrete
Verdict: Choose KILZ if you want a one-part coating with clearly described residential uses and coverage guidance for different concrete textures.
2. SHENGWEI 3-Gallon Epoxy Paint: A Larger Package for Broad Floors
This SHENGWEI option is a dark-gray, one-part, water-based floor coating sold in a 3-gallon package. Its listing gives a total coverage figure of 360 square feet. Because that estimate is tied to the package, compare it with your measured floor area and check the product instructions for coverage details before buying.
The ready-to-use formula does not require mixing Part A and Part B; the description says to stir and apply it with a roller or brush. It is listed for garages, workshops, basements, and other concrete surfaces. The maker describes it as low odor and fast drying, with soap-and-water cleanup.
The product description also says the coating is intended to help protect against foot traffic, moisture, oil stains, and common household chemicals. That may make it worth considering for everyday-use spaces, but the listing provides less surface-specific guidance than KILZ. If your floor has unusual moisture conditions or heavy equipment use, verify suitability with the manufacturer before proceeding.
The 3-gallon package is the main point of difference from the other choices. It may be convenient when the listed coverage fits your project, while the 1-gallon SHENGWEI package is sized for a smaller area. Do not assume the 3-gallon option covers more than the listed 360 square feet; use the product’s stated figure when planning.
Pros:
- Ready-to-use, single-component formula
- Listed for garages, workshops, basements, and other concrete surfaces
- Dark-gray color is described as helping conceal dirt, tire marks, and minor imperfections
- Soap-and-water cleanup is listed
Cons:
- The listed coverage is 360 square feet for the 3-gallon package, so check your area carefully
- The product description gives less detail about surface-specific limitations than KILZ
Verdict: Consider the 3-gallon SHENGWEI option if its stated coverage suits your floor and you want a ready-to-use coating for a garage, workshop, or basement.
3. SHENGWEI 1-Gallon Epoxy Paint: A Smaller Package for Compact Areas
This one-gallon SHENGWEI coating shares the dark-gray color and ready-to-use, water-based formula of the larger package. The listing says one gallon covers up to 120 square feet. That makes it easier to match to a compact floor than a larger package, though “up to” coverage should be treated as an estimate rather than a guarantee for every surface.
As with the 3-gallon version, the formula does not require combining two parts. The product description says to stir it and apply it with a roller or brush. It is listed for concrete floors in garages, workshops, basements, and other residential or commercial spaces, and is described as low odor, fast drying, and easy to clean up with soap and water.
The listed coating is intended to help protect against everyday foot traffic, moisture, oil stains, and common household chemicals. The description does not give the same detailed coverage ranges for smooth and rough concrete that KILZ provides, so measure your floor and check the label for application instructions and any surface restrictions.
Compared with the 3-gallon SHENGWEI option, the one-gallon version has a smaller stated coverage area and may be a more suitable package size for a limited project. Compared with KILZ, it has less information about indoor and outdoor applications and specific exclusions. That difference matters if your floor has demanding conditions.
Pros:
- One-gallon package with coverage stated at up to 120 square feet
- Ready-to-use formula requires no Part A and Part B mixing
- Listed for garages, workshops, basements, and other concrete surfaces
- Water-based cleanup with soap and water
Cons:
- Coverage is limited compared with the larger package
- Listing provides limited detail about surface conditions and exclusions
Verdict: Pick the one-gallon SHENGWEI option for a smaller concrete floor when its stated coverage and application guidance match your project.
How to Choose One Part Epoxy Floor Paint
Match the coating to the floor and location
Check whether the product is intended for your type of surface and whether it can be used indoors, outdoors, or both. KILZ is listed for properly prepared porous concrete, masonry, stone, and brick, and for interior and exterior horizontal surfaces. SHENGWEI lists garages, workshops, basements, and other concrete surfaces. Follow the label if your floor is painted, sealed, unusually porous, or otherwise different from bare concrete.
Measure the floor and account for texture
Measure the length and width of the area, then multiply them to estimate square footage. Compare that number with the product’s coverage information. KILZ gives separate ranges for smooth and rough surfaces, while the SHENGWEI one-gallon listing says up to 120 square feet and its 3-gallon listing says 360 square feet. Rough or absorbent concrete may require more coating, so avoid planning around the most optimistic estimate alone.
Choose a package size that fits your project
The right package can help limit leftover paint, but a small shortfall can interrupt the job. The SHENGWEI options come in one- and three-gallon listings with different stated coverage. Compare those figures against your measured area and the label’s application guidance. KILZ is listed as a one-gallon product, with coverage that depends on surface texture.
Consider how the space is used
Think about foot traffic, vehicle use, spills, and equipment. KILZ describes resistance to hot tire pickup and several forms of wear, but excludes forklift traffic and areas exposed to hydrostatic pressure. SHENGWEI describes protection for everyday foot traffic, moisture, oil stains, and common household chemicals. These descriptions do not mean every coating suits every level of use, so check the full product instructions for your conditions.
Plan for surface preparation
Floor coatings depend on a suitable, properly prepared surface. Before painting, remove dirt and loose material, and follow the product label for cleaning, drying, and any other preparation steps. Pay attention to moisture and existing coatings; KILZ specifically excludes areas exposed to hydrostatic pressure. If you are unsure whether the floor is ready, resolve that question before applying paint rather than relying on the coating to hide a surface problem.
Check application and cleanup details
All three products are described as one-part coatings that can be applied with a roller or brush. KILZ and SHENGWEI are water-based, and their descriptions specify soap-and-water cleanup. SHENGWEI says to stir before use and describes the formula as low odor and fast drying. Consult the product label for application conditions, drying times, recoat guidance, and when the floor can return to service; those details are not fully provided in the product information here.
Frequently Asked Questions
What does “one part” mean for floor paint?
A one-part coating is supplied as a single ready-to-use formula rather than requiring you to combine separate Part A and Part B components. The SHENGWEI listings explicitly describe their formulas as ready to use. Always follow the product directions, including any stirring instructions.
Is one-part epoxy floor paint suitable for a garage?
The products here are listed for garage floors or garage concrete, but suitability depends on the floor and how the space is used. KILZ is described as resisting hot tire pickup, while excluding forklift traffic. Check the label for surface preparation and use limitations before painting.
How much paint should I buy?
Measure the floor and compare its square footage with the product’s stated coverage. For KILZ, use the lower coverage range if your concrete is rough. The SHENGWEI listings state 120 square feet for one gallon and 360 square feet for three gallons. Actual coverage can depend on the surface, so read the package directions before deciding how much to buy.
Can these products be applied with a roller?
Yes. Each product description lists roller application; brush application is also mentioned. Follow the product directions for the recommended tools and application method.
Can I use these coatings outdoors?
KILZ is explicitly listed for interior and exterior horizontal surfaces, including areas such as porches, driveways, and pool decks. The SHENGWEI descriptions focus on garages, workshops, basements, and other concrete surfaces but do not provide the same specific outdoor examples. Check the label if you plan to coat an exposed outdoor floor.
Can I use these products where moisture is coming through the concrete?
KILZ is specifically listed as unsuitable for areas exposed to hydrostatic pressure. The SHENGWEI descriptions do not provide enough detail to confirm suitability for that condition. Identify the source of moisture and check with the manufacturer before coating the floor.
Final Recommendation
KILZ is the strongest all-around choice in this comparison for shoppers who want clearly stated indoor and outdoor uses, coverage ranges by concrete texture, and specific limitations. Choose SHENGWEI’s three-gallon package when its stated coverage fits a larger project, or its one-gallon option for a smaller area. Whichever you select, verify the surface is suitable, prepare it as directed, and use the label’s coverage and application instructions to plan the job.
