Basement floors often suffer from being dull, drab, and neglected. However, with a little effort and the right materials, you can transform your concrete basement floor into a durable, attractive surface. Epoxy paint kits are perfect for this job, providing a tough, long-lasting finish that is resistant to stains, chemicals, and wear.
Here’s a comprehensive guide to help you paint your concrete basement floors using an epoxy paint kit.

Our Unfinished Basement Makeover
When we moved into our home two years ago, our unfinished basement was kinda creepy and we mainly used it for storage.
While in quarantine in 2020, we realized that our kids needed a dedicated space to run around and play with their toys. We created a makeshift playroom in the unfinished basement and it worked out great!
This year, I really wanted to give our unfinished basement a more finished look and began planning a budget-friendly basement makeover.
When going through our flooring options, I decided to use Rust-Oleum’s Epoxyshield Garage Floor Coating kit instead of carpeting because of its durability and clean finish.
With two kids and three dogs, I wanted low-maintenance floors where we didn’t have to work about spills or accidents.
The drab concrete floor went from looking like this:

When painting surfaces, like a concrete floor, it is important to use the right type of paint. An epoxy paint is much more durable than your standard interior latex paint.

- Rust-Oleum Epoxyshield Garage Floor Coating Kit – $200 per kit, I used 6 (gifted)
- Anti-Skid Additive – $15 per bag, (I used 6) (gifted)
- Rust-Oleum Cleaner & Degreaser $22 (gifted)
- Scrub Brush – $8
- 5 gallon Bucket – $0 (owned)
- Watering Can – $0 (owned)
- Squeegee – $30
- 3/8 inch nap Roller Sleeve – $5

- Wet / Dry Vacuum– $0 (owned)
- Paint tray – $0 (owned)
- Paint Mixer– $0 (owned)
- Paintbrush– $0 (owned)
Step 1 | Measure the Room
Measure the size of the concrete surface to determine how much paint and the number of kits to purchase. My basement was roughly 1,500 square feet, so I purchased 7 kits and used 6.
Choose Your Paint Color
You can find the Epoxyshield Garage Floor Coating kit at your local Home Depot. The Epoxyshield Garage Floor Coating kit is 5x more durable than one part epoxy on interior concrete floors. If garage floor paint is strong enough to withstand a car driving on the surface, I know it will be strong enough to withstand high-traffic areas in our basement!
This particular paint kit offers various colors to choose from and must be mixed by the paint department at the store.
From their color options, I chose the paint color, New Concrete, for our floors because it is a light, neutral color that will go nicely with all of our furniture.
If you want to order the product directly to your house or curbside pick-up, Rust-Oleum offers a premixed option, EpoxyShield Garage Floor Coating Kit in Gray Gloss, Dark Gray, or Tan. They come in 2.5 car kits so you won’t need to order as many kits.
**I accidentally forgot this step and used an entire untinted kit before noticing that it was not the correct color. I don’t think it registered right away because I chose such a light tint. I took it all back to Home Depot and the nice woman at the paint desk let me know that I essentially painted a can of glue on the floors!
Each kit includes one base gallon (Part B), one quart of the activator (Part A), a mixing stick, a bag of concrete etch, and decorative chips.
Step 2 | Clean the Concrete Basement Floors
First, I began removing all items from the entire floor and thoroughly sweeping the surface with a broom and shop vacuum.
Clean & Degrease the Concrete Floors
Next, I used the Rust-Oleum Cleaner and Degreaser solution to remove as much dirt and concrete stains as possible before applying the new paint.
I followed the instructions on the bottle and mixed the solution with water in a large bucket.
Working in sections, I poured the cleaning solution onto the concrete. I used a deck scrub brush to clean the surface to remove as much dirt as possible.
Sometimes a section of the concrete would begin to dry up before I removed the dirty water, so I would pour clean water over those sections.
Squeegee and Vacuum Dirty Water
Next, I used a floor squeegee to pool the dirty water together and vacuum up the dirty water.
Cleaning the concrete basement floors took a full day to complete because of the size of the basement (1,500 SF) and the process of carrying the shop vac upstairs and dumping out the water. For the best results, it is important to have a clean floor to ensure paint adhesion.
Step 3 | Etch the Concrete Flooring (Optional)
Disclaimer: Etching the basement floor adds durability and increases adhesion, but this step is not required. If you are using his product on your garage floors, etching is an important step for durability with cars driving on it.
Mix the bag of concrete etch provided in the kit with 2 gallons of water in a watering can until it is dissolved.
Using a hose, pre-wet the floors and evenly distribute the etching solution over the bare concrete floor. Vigorously scrub the floors with the bristle brush to loosen dust and dirt.
Once you have finished scrubbing, use the floor squeegee to pool the solution together and remove it with a shop vac.
Step 4 | Rinse the Concrete Floor & Dry
Rinse the floor with water one more time to remove any remaining etch solution.
Use the squeegee and vacuum to remove the water from the floor. Once the floor is dry, rub your fingers over the ground.
If dust or powder comes off, repeat scrubbing and rinsing until the floor is clean. Turn on a few fans and allow the floors to dry for 24 hours.
Step 5 | Mix Part A & Part B Together
To activate the epoxy floor paint, mix the two cans in the kit together to begin the chemical reaction.
I poured Part A, the activator, into the gallon can of Part B, the base. The two cans should be mixed thoroughly for 3 minutes.
I tried the stir stick with the first kit, but it wasn’t mixing well. I quickly upgraded to the paddle paint mixer attachment for my drill.
For an additional cost (not in the kit), I added Rust-Oleum Anti-Skid Additive to the epoxy mix. This helps to prevent slipping when the floor inevitably gets wet.
When the epoxy floor paint is mixed, it has been activated and should be applied within the set time frame indicated in the instructions. Luckily, this particular paint kit has a low odor, however, I recommend you open windows for ventilation if it is possible in your basement.
Step 6 | Apply Basement Floor Paint
When you are ready to begin, choose the furthest corner of the room and work your way toward the exit.
Working in 4×4 sections, use a synthetic paintbrush to first trim the edges of the basement with the epoxy paint.
Use a ⅜ inch nap and 9” paint roller frame to apply the floor paint in the 4×4 section.
Continue brushing the edges and rolling the paint until you complete the concrete basement floors.
I skipped the step where you sprinkle decorative chips on the wet paint. The chips are included in the kit and provide a textured finish. The solid color on the concrete floors has a smooth finish, which I prefer.
This product only requires one coat of paint, however, you may be able to see dark blemishes with the lighter tints.
Before painting our floors, I filled a few hairline cracks. First, I removed any debris from the cracks using a wire brush. Next, I used a putty knife to fill the cracks with dark gray concrete filler.
You can see where I filled in the cracks with a single coat of epoxy paint.
I applied a second coat of paint to this area and the darker spots went away!
There were a few small spots on the floor that would not take the epoxy paint. I must not have removed all of the gunk from the floors.
Once the first coat of paint dried, I fixed these spots by painting a second coat on the areas where the concrete was showing.
It was an easy fix and they blend seamlessly into the concrete floors!
After my touch-ups, I allowed the painted concrete floor 24 hours to dry and then put the basement back together!

This was a pretty physical DIY project and a lot of hard work, but totally worth it to get these results. While I wouldn’t say this was an easy job, I do think using a paint kit made this project easier than purchasing all of the materials separately.
With the kit, we didn’t have to apply a primer coat or concrete sealer which simplified the process. This made the epoxy floor paint kit the best choice for us.
By choosing a basement floor paint that can be used in a garage as well, I know they will be durable and withstand the wear and tear of our family.
I hope you found this DIY helpful and that it gives you the courage to try it yourself and update the look of your basement!

Common Questions When Painting Concrete Floors
How much did it cost to paint the basement floors?
Based on the paint product alone and for the size of my basement. (1,500 sq ft), the cost was around $1,300.
The remaining cost will vary based. on materials you already own, for example, I did not need to purchase a wet vac. Check out the source list above to see all of the materials needed and a link with their cost.
In full transparency, I partnered with Rust-Oleum for this DIY project, so the cost was minimal to purchase the remaining supplies (less than $100).
Does the basement floor paint smell bad or have fumes?
In my opinion, the fumes from the concrete paint were not bad at all. I had fans going and two open windows so it was not a super strong smell.
There is definitely an odor but it is not as strong as an oil-based primer, for example.
How have the painted basement floors held up?
It has been over three years since painting the concrete basement floors and they still look great! We are in the basement every day either working out or the kids running around and playing. There is a lot of activity on the floors and I haven’t noticed any wear and tear.

The cost will depend on the size of your basement and how many kits are needed. For my basement I estimated 1,500 SF (6 kits) and the cost of the paint materials was about $1,300.

Not bad at all. I had fans going and the two basement windows cracked so it was not a super strong smell. There is definitely an odor but it is not as strong as an oil-based primer, in my opinion.
