By the end of this post, you’ll be feeling very confident about how to seal butcher block!
Let’s get into it.
Butcher Block Polycrylic or Oil
If you didn’t know that you needed to seal butcher block, now you do. 🙂
However, a quick Google search on sealing butcher block may make things more confusing than simple.
Polycrylic? Polyurethane? Tung oil? Mineral oil? There are plenty of options, but what is the best sealer for butcher block? The answer is: it’s really up to personal preference. BUT I do highly recommend one over the others.
Why I recommend Polycrylic
Once you’ve stained that beautiful piece of wood your desired color, Polycrylic will make sure it stays as beautiful as day 1!
Polycrylic creates a water-resistant barrier around your butcher block. There’s no risk of staining with spills or anything else. There is no penetrating this stuff, so there’s zero worry in that department.
You also only need to seal once (2-3 coats) with Polycrylic. After that? You’re done. For a very long time before ever thinking about having to retouch!
The process of applying Polycrylic is super easy, in fact, I’ll take you through step-by-step how to seal butcher block with Polycrylic at the end of this post. That way you can feel extremely confident doing it yourself!
Need a butcher block to seal?
I’ve used the Hardwood Reflections butcher block from Home Depot for both my DIY kitchen table and DIY home office desk. Let me just say the results are incredible. Like sometimes I just sit and stare at them lol. They’re that pretty!
It comes in different sizes for all of your project needs, as well as different types of wood. Birch is what I’ve used and will continue to use for my future projects.
It comes pre-sanded which is easier for staining (if you choose to stain your butcher block), and it’s just so simple to work with. 10 out of 10, highly recommend!
Is Polycrylic actually polyurethane?
The short answer: No!
There’s a big debate about whether or not Polycrylic is the same as polyurethane. So I reached out to the source themselves to settle it: Minwax!
Minwax plainly stated that Polycrylic is not considered a polyurethane. So there you have it!
Polycrylic is in a league of its own. It’s a water-based protective top coat that contains urethane (yes the other half of poly-urethane). But it’s acrylic based – hence Poly-crylic. So it has similar protective qualities as polyurethane.
I call it the DIYers polyurethane, although it’s not a polyurethane. Just because it essentially does the same thing and it’s seriously SO easy to work with.
So is Polycrylic the same as polyurethane? It has been officially stated that it’s not.
While there are similarities between Polycrylic and polyurethane, it’s important for the DIYer to know the difference, and where to use each product.
Polycrylic
- Polycrylic is the name of a water-based top coat product created by Minwax.
- Best when used to seal indoor projects or low-traffic areas to protect surfaces against damage. Indoor use only.
- Eco-friendly, has lower VOCs (so less toxic vapors), and for the DIYer, it dries very quickly.
- Provides you with a crystal clear protective finish. If you want your wood, stained or not, to retain as much of its natural color as possible, use Polycrylic!
- While it’s durable, it’s not as durable as oil-based polyurethane. Polycrylic and water-based polyurethane are both prone to scratching because they’re both water-based. But oil-based polyurethane will be ever-so-stronger.
- According to Minwax, Polycrylic is non-flammable.
Polyurethane
- Polyurethane can come in oil-based or water-based finishes.
- Best used for sealing outdoor surfaces that are exposed to the elements or high-traffic areas. It’s also very common to finish real hardwood floors with oil-based polyurethane because of its durability.
- Higher VOCs when compared to Polycrylic and takes longer to dry.
- Water-based polyurethane is more prone to scratching, similar to Polycrylic, because of its hard clear coat.
- Oil-based polyurethane is more prone to denting because the final result is a tad softer than water-based – but it’s better against scratches, moisture, and heat.
- Oil-based polyurethane gives wood a slight amber-ish, yellow-ish hue.
- Oil-based polyurethane is also flammable, while water-based is not. This mostly applies to the wet product and fumes, but I would still exercise caution in both wet and dried states for both types of polyurethane.
Can you seal butcher block with polyurethane? Absolutely! You’ll have to weigh the advantages and disadvantages of polyurethane and Polycrylic.
But this post is all about how to seal butcher block with Polycrylic. 🙂
My personal thoughts on it: I will still pick Polycrylic over water-based or oil-based polyurethane for sealing butcher block, or any other project. Why? Because it’s a lot easier to work with, it’s less harmful for you, and while it’s not as durable as polyurethane, it’s pretty dang durable!
Is Polycrylic food safe for butcher block?
The short answer: Yes!
You’ve probably seen some buzz when searching around whether Polycrylic and polyurethane, are food-grade and safe in your kitchen.
Yes, Polycrylic is essentially a thin coat of plastic between your wood butcher block surface and you. But here’s the comforting bit.
The FDA approves polyurethane (which would include Polycrylic in this instance) in its cured state as safe for contact with food. Just remember, cured does not mean dry. Once dry, it’s still going through a chemical process for up to 30 days to become cured.
At the end of this curing process, Polycrylic and polyurethane are considered non-toxic and safe to come in contact with food. So there’s really no specific “food grade polyurethane for butcher block”. Cured Polycrylic and polyurethane are safe for contact with food!
With that being said, I would NOT, and I repeat AVOID, chopping food with a knife directly on a surface that has been sealed with Polycrylic or polyurethane.
Why? Because while food touching cured Polycrylic and polyurethane is safe, if you’re chopping directly on top of the butcher block then of course you’re risking getting particles in your food.
Now I don’t know many people that chop food directly on their countertops, but the SUPER simple fix for this is, you guessed it, use a cutting board!
But that goes with anything. I mean think about chopping on really any surface, you’re going to deal with the same thing, it’s not just sealed butcher block.
So while you may see plenty online about Polycrylic and polyurethane being toxic or not food safe when coming in contact with food, it’s simply not true.
As long as you allow Polycrylic to cure for 30 days after applying, and you’re not chopping directly on it, you shouldn’t have any worries.
I did the research for you!
For further reassurance, I use Polycrylic to seal all of my DIY projects involving stain and wood. I’ve had plenty of experience with sealing, and I truly care about ensuring what I’m doing is safe for my family and me.
I wouldn’t do it if I didn’t fully trust the safety of the product and I’ve done LOTS of research on the subject.
In fact, I sealed my own DIY butcher block kitchen table several years ago with Polycrylic and I’m so happy that I did.
Whether it’s butcher block countertops, a butcher block desk, or a butcher block table, I HIGHLY recommend using Polycrylic to seal butcher block.
Drying time vs. Curing time: when can I use my newly sealed butcher block?
When using Minwax Polycrylic, you’re ready to use your sealed butcher block after 24 hours of applying your last coat…with caution! What do I mean by “…with caution”? Don’t let that freak you out! Let me explain to alleviate any anxiety.
After 24 hours, your top coat will be completely dry to the touch. However, it still needs to go through the curing process, which takes 30 days.
What does curing mean? Curing is the molecular process that Polycrylic and polyurethane undergo when exposed to oxygen, which allows it to bind and be as strong as it will ever be. As I just mentioned, this process does take 30 days. Bet you didn’t think you’d have a little science lesson today haha.
That doesn’t mean you can’t use your butcher block for 30 days, that just means you have to be a little more gentle than you typically would when using a countertop. During this period of time, while all of the fun science is happening in the background, your sealed surface is a little more prone to scratching before it’s completely cured.
Essentially, just be attentive to how you are using your sealed butcher block.
Place down, pick up, no scooting – those are your instructions for the next 30 days. 😉
For kitchen countertops, maybe opt for a silicone heat-resistant mat. This might be a nice-to-have long-term since Polycrylic is not heat-resistant like some stone countertops. For desks, you could use a desk mat.
After 30 days, you’re in the clear to drop the “caution” and use your butcher block how you typically would use any other surface.
How do you permanently seal a butcher block?
You may also be asking yourself, how often do you have to seal butcher block?
Well, I’m here to tell you that’s another advantage of Polycrylic – it permanently seals! And better yet, you only have to seal it one time (2-3 coats) and it’s good for a very long time. Of course, the caveat there is if you ever get any scratches, you may want to touch up your surface.
If you use tung oil or mineral oil to seal your butcher block, it’s a different story.
Tung oil will need at least 6-7 coats, if not more over time for touch-ups. This type of sealer requires a lot of patience as it penetrates very slowly, taking at least a couple of days with each coat to completely dry. It’s also pretty expensive considering you will need a good amount of it, and likely won’t be a one-time buy.
Mineral oil needs to be applied almost once a month, or in other words, a lot more than the other types of sealers! That means removing the items from your countertop, table, or desk month after month just to seal. I don’t know about you, but I don’t have time for that!
To help explain the difference even further, the oil sealers soak into the wood for protection, whereas the Polycrylic adds an extremely thin layer of protection on top of the surface.
Polycrylic Advantages and Disadvantages
Let’s take a look at the advantages and disadvantages of using Polycrylic as a sealer for your butcher block.
There truly aren’t that many disadvantages, unless you’re completely set on using your butcher block countertop as one large chopping block.
Polycrylic Advantages
- Fast drying (2 hours)
- Food safe once cured (30 days after applying)
- Semi-permanent – just one time (2-3 coats) and you’re good! Semi-permanent, because you can always sand it down.
- Creates a water-resistant seal around your stained butcher block – making it spill-proof. While it will protect your wood from water damage, Minwax still does not consider the product waterproof. But when they say it’s not waterproof, they’re talking about outdoor application exposed to rainy days kind of waterproof.
- Less time-consuming process
- Easy to apply
- According to Minwax, non-flammable
Polycrylic Disadvantages
- Cannot use your countertop for chopping
- Polyurethanes can yellow over time depending on the product, but that’s more just a general statement for polyurethane – Polycrylic doesn’t really have this issue as it’s a water-based clear coat
- Some say Polycrylic can have a slightly unnatural sheen, but I’ll let you decide!
Tung Oil Advantages and Disadvantages
Now that we’ve covered the good and the bad of Polycrylic, let’s take a look at the advantages and disadvantages of using tung oil!
Tung Oil Advantages
- Completely non-toxic options for directly chopping on a countertop – not all tung oils are food grade, so be sure to do your research!
- Provides a natural shine – lets the stain do the talking
- No yellowing over time
- Easy to apply
Tung Oil Disadvantages
- Multiple coats (6-7) with additional for upkeep over time
- Slow penetration – up to 5 days to completely dry with each coat
- Susceptible to damage from water
Something Polycrylic and tung oil also both have in common is that they do NOT smell good. So crack those windows open, get that mask on, and get the fans going!
How to clean a surface sealed with Polycrylic?
Whether it’s a butcher block kitchen table, or butcher block countertops, you’re going to need to clean your sealed surfaces after use.
The good news is that you can use a simple all-purpose cleaner spray to clean a surface sealed with Polycrylic.
My go-to that I’ve been using on my butcher block kitchen table for years is the Method All-Purpose cleaner. I especially love the Pink Grapefruit scent!
What is the best product for sealing butcher block?
Minwax Polycrylic Water-Based sealer is hands down the best way to seal butcher block! Get it in Clear Satin.
I know a lot of people ask “Can I use Minwax Polycrylic on butcher block?” And the answer is, that’s the ONLY thing I recommend.
As I said, I have used Polycrylic to seal all of my staining and wood projects, and I have never used anything different.
Remember how I said there’s a product that won’t yellow over time? Well, this is it! Minwax Polycrylic is one of the best, if not THE best, top coats you can use for non-yellowing because it is water-based and it dries as a crystal clear coat. Only oil-based polyurethanes will yellow.
For even more reassurance, I have a piece in my home that I sealed with Minwax Polycrylic water-based sealer 10 years ago, and guess what? No yellowing!
Polycrylic is available in the following sheens: Clear Satin, Clear Semi-Gloss, and Clear Gloss. But like I mentioned earlier, the glossier the finish, the more apparent any future scratches might be.
I find that Clear Satin is pretty close to a matte finish, but you will catch the slightest shine depending on the lighting and angle (as seen in the pics). This is perfect for my liking, but everyone has their own taste! ☺️
How to seal butcher block with Polycrylic (step-by-step guide)
Now the moment you’ve been waiting for, a step-by-step guide on how to seal butcher block with Polycrylic! The best part is, it’s EXTREMELY easy and you’ll be done in no time.
It’ll only take you about 10-15 minutes to actually do the work, between putting the Polycrylic on and sanding it once dried. The majority of the time is just waiting for the thing to dry!
First and foremost, don’t shake Polycrylic, or polyurethane in general! Mix it with a stirring stick.
And at this point, I am assuming you have already gone through the staining process. You MUST stain before sealing (if you are choosing to stain your butcher block). So if you haven’t done that yet, I’ll be here waiting. 🙂 Essentially, once the Polycrylic is on, staining cannot happen.

And here’s an extremely important fact about those rags you used for staining. You MUST safely dispose of staining rags as they are highly flammable.
Read this article, How to Safely Dispose of Staining/Rags Materials by Handmade Home Co.
Materials Needed
- Minwax Polycrylic Water-Based Sealer (Clear Satin)
- Sponge Brush
- 220-Grit Sandpaper
- Microfiber Cloth or Paper Towels
- N95 Particle Masks (it’s about to get stinky!)
To get started, we will need 3 coats. Oh, and now might be a good time to open those windows for the smell!
1. The First Coat of Polycrylic
Using a new sponge brush, begin to brush on the Polycrylic. Be sure to go with the grain of the wood so that it blends nicely with the butcher block.
Just get a thin layer on there, no need to go crazy with it! Enough to cover the surface.
With Minwax Polycrylic, it is a fast-drying top coat so you should be good to sand after 2 hours.
If you’re making a DIY butcher block desk or DIY butcher block kitchen table like I have, you’ll want to ensure that you flip the piece over and do the other side once dry. But for countertops, lucky for you, you’ll only have to do the top and sides of the butcher block.
2. LIGHTLY Sand!
Once your first coat is dry, take your 220-grit sandpaper and LIGHTLY sand going with the grain of the wood. I repeat, LIGHTLY start sanding the entire surface of your butcher block. You should just barely be applying pressure with the sandpaper.
The main goal of why we are sanding is so we can get the first coat to a point where it’s rid of all small bumps and any other imperfections. Do this over the entire surface not just the visible imperfections, so it evens out the entire piece.
Take a damp microfiber towel, and wipe down the entire surface to get rid of particles before the second coat of Polycrylic. The dampness will make it easier for particles to stick to your cloth so you can completely remove them from the surface.
3. Additional Coats of Polycrylic
Each coat of Polycrylic will be the same exact thing as the first coat. Apply Polycrylic, let it dry, then sand it. I recommend at least 2-3 coats of Polycrylic to ensure your piece is nice and protected.
When you get to the last coat of Polycrylic, you will NOT be sanding once dried.
With this being said, for your last coat, be sure to brush on the Polycrylic with nice even strokes since what you see is what you’ll get!
Again, just enough Polycrylic to cover the surface of your butcher block, and be sure to go with the grain of the wood. Don’t cake it on there. 😜
