Stained concrete floors are beautiful! But many DIY’ers, including myself, have wondered can wood stain be used on concrete?
Here’s what I discovered:
Wood stain can be used to stain concrete. However, wood stain will be like painting the concrete where it just sticks to the surface (which over time can scrape off). Acid stain, by comparison, leeches into the concrete and becomes part of the concrete.
But there’s a lot more to know about concrete staining and how wood stain works on it.
Originally used mostly in stores, stained concrete floors came into fashion for homes in the late 1990s. We love the look of the swirled colors, the durability, and the ease of keeping them clean.
So in today’s post, we’ll be exploring some of the top questions about concrete staining. We’ll look at questions around sealers, stain rollers, and concrete curing. But specifically, we’ll answer the question “can wood stain be used on concrete?”

How do you use a stain roller on concrete?
Use a stain roller and a long extended pole to apply stain to concrete. Because stain is thinner than paint, don’t apply too much stain to the roller or it will drip excessively on the concrete. Roll in one direction only, and make sure to avoid overlapping lines.
For solid color concrete stain (the finished result will look more like you painted it), a roller works just fine.
You’ll want to start with a clean, washed, and dry surface.
As we get into below, you also want to wait at least 30 days if the concrete is new and was just poured. But if your concrete is prepped, clean, and ready to go, simply roll the stain on using long strokes of equal pressure.
Also, make sure the air temp is not too cold or too hot; between 50-90 degrees. 2 coats may be required for the best look.
All that being said if you are using an acid-based stain and/or a transparent or semi-transparent, I would recommend using a backpack sprayer rather than a paint roller.
It will go on smoother and easier and be less likely to show any lines.
The Field King Professional Backpack Sprayer rates 4.5 stars on Amazon with well over 500 reviews. Just click the link to see the current Amazon price.
It comes with free shipping too and is an Amazon’s Choice product, so you know this is the best of the best. I wouldn’t apply concrete stain (and I have) with anything else!
Cleaning concrete floors is one of the best parts about having this type of floor.
Make sure and check out one of my top posts that shows you just how easy is it is to Clean Stained Concrete Floors with Vinegar. My post walks you through the simple and easy process. What really surprised me was how little vinegar you need for a great shine!
How long must concrete cure before staining?
Wait at least 1 month after the concrete was poured before applying stain. Concrete needs to cure completely before staining or sealing, and the curing process allows the excess water in the concrete to evaporate.
If you don’t allow it to evaporate, then any stains or sealers won’t soak into the concrete and may end up flaking off.
However, some brands recommend up to 60 days, so always read the instructions (admittedly hard for some of us guys).
With most acid stains, concrete paints or sealers,
That being said, temperature, humidity, and how stiff the concrete was mixed all factor in too.
So to really be completely safe, I would wait 45 days. After all, what are another 15 days to ensure you end up with really beautiful stained concrete floors?

Can you stain over sealed concrete?
You can stain over sealed concrete. But, you can’t just apply the stain on top of the sealed concrete. If you do, the stain will likely flake off. So first remove the sealer on the floor and stain, or apply a thin layer of acrylic polymer-modified concrete on top of the floors and then apply new stain 24 hours later.
After all, an acid stain is designed to soak into the concrete, not just lay on top of it like a coat of paint.
Thus, if you have sealed floors and don’t treat them, the stain will just sit on the surface and be vulnerable to foot traffic and furniture.
So to apply a stain on sealed concrete, you really have 2 options to ensure it looks good:
- Remove the sealer and apply the stain
- Apply a thin layer (1/8″ thick) of acrylic polymer-modified concrete on top of the concrete and apply the stain to that (after at least 24 hours)
Instructions for both methods are below.

Removing sealer from a sealed concrete floor
This is not a fun job, just FYI.
To remove sealer from a concrete floor you can either grind it off by renting a floor sander from Home Depot or you can use a solvent-based stripper to remove it.
Solvent-based strippers (typically Methylene-chloride based) work quickly but as you would imagine they can be hazardous to breathe and dangerous if it gets on your skin, eyes, etc.
Thus make sure you have good ventilation and consider using a respirator.
Once it’s been applied, you’ll be left with a goo mixture on your concrete which must be completely removed.
Use a long-handled floor scraper and scrape the mixture up and dispose into an appropriate container and always follow your state’s regulations on disposal.
Then use hot water and liquid soap to thoroughly clean the floor.
Rinse thoroughly and allow to dry completely before proceeding.

- Use a floor sander with 60 grit sanding screen over the entire floor. Grind for about 15 minutes using smooth constant slow movement for a room about 15’x15′.
- Rinse the floor with a gentle floor cleaner and allow to dry.
- Lay down a heavy coat of acrylic primer, using a long-handled paint roller.
- Wait at least 10 hours before proceeding with the next step.
- Add a 2nd, thinner coat of the primer.
- Allow it to dry to the touch.
- Apply the polymer-modified concrete overlay, such as Akona® Polymer-Modified Concrete Resurfacer, at 1/8″ thick. Apply using a trowel or long-handled squeegee.
- Wait at least 24 hours before proceeding with the next step.
- Apply the acid stain using a backpack sprayer. Follow the steps provided by the stain manufacturer, but typically you would allow it to dry for 3-4 hours before applying additional coats as desired.
- Once you have applied all the coats of stain you wish to apply, we need to neutralize the acid.
- We do this easily by simply mixing TSP and water and mopping it on and scrubbing it in.
- Then rinse with water only enough times to completely remove any residue. Use a wet/dry vac to suck up all the extra water.
- Allow your new stained concrete to dry for at least 24 hours. Then you can sealer using a water, acrylic or solvent-based sealer and wax if desired.

How much does it cost to stain concrete floors yourself?
The cost to stain a concrete floor yourself is going to start at about $500, including stain, sealer, backpack sprayer, and rental of a floor sander. The size of the room(s) and the condition of the current floor or subfloor can impact that amount significantly though.
If you’re seriously considering staining your concrete floors yourself, you will definitely want to check out my Step-by-Step Concrete Staining Guide of exactly how I did it (including all my mistakes you’ll want to avoid. Just click to read it on my site.
I show you every step of the process and cover all the questions and challenges you’ll likely have.
That being said, which you could easily spend between $2,000-$5,000 hiring a professional, I spent under $500 staining my own concrete floors (a dining room and kitchen).
Looks like someone was murdered here! The builders got sloppy with the wood stain. I’m leaving the concrete slab exposed, because this will be the floor of my studio. I’ll clean up those stains with a solvent. pic.twitter.com/usKVLaucJ5

What is the difference between wood stain and concrete stain?
Wood stain is essentially like thin paint and will coat a concrete floor, sticking to its surface. Acid-based concrete stain, by comparison, chemically reacts to the concrete, and soaks in, becoming a permanent part of the concrete. Non-acid-based concrete stains are also more like paint.
So we know wood stain can be used on concrete.
That being said, I would personally not use wood stain.
While it’s true that places like Home Depot and Lowe’s don’t typically carry acid-based concrete stain, unless you live in the backwoods, most likely there is at least 1 store in your town that deals in professional acid stain products.
Alternately you can also order acid stain on the internet.
The reason I say no to “can wood stain be used on concrete” is that it’s coating the concrete more than becoming part of it.
Concrete is porous and the wood stain may soak in to a degree, but acid stain actually has a chemical reaction with the concrete that helps ensure a smoother and deeper bond between the stain and the floor.
If you absolutely have to use wood stain, just be prepared for it to flake off easily and to reapply it regularly.
Did I cover all your questions about can wood stain be used on concrete?
Today we took a fairly quick look into some of the top questions around concrete staining.
We answered questions that many DIYers have on sealed concrete, new concrete and application techniques.
But specifically, we answered the question “can wood stain be used on concrete?”
And yes, we technically you can stain concrete with wood stain, I would recommend against that.
