How To Choose Right Concrete Sealer For Countertops?

How To Choose Right Concrete Sealer For Countertops?

Maybe you’ve been expecting a name so far to call it the best concrete countertop sealer. But the truth is, it’s only you who can choose which one is going to be that for you. For that, all you need to do is make sure you’re checking out the following things.


When you want to do nothing but keep your countertop good as new for the longest period of time, make sure you’re choosing the one with deeper penetration ability. They basically create a barrier so sturdy that it becomes next to impossible to wear or peel any sooner.

The only drawback they come with is the price as they’re kind of expensive. But quality doesn’t always come at a cheaper price, right?

Yup, there’s a cheaper alternative too and it’s the film-forming one that we’re talking about. Though they’re good with creating a nice protective layer but require frequent reapplication. So, if you’re more into improving the look, then this is what you need to go for.


What is the size of a regular concrete countertop? Around 30 to 40 sq. ft., right? So, when you’re about to grab a sealer, make sure that the one you’re choosing is capable of covering your desired area even if you’ve got a bigger countertop than regular.

As you might need two or more coats in order to give it a more durable layer, its quantity has to be up to that mark. Otherwise, you might have to go for a repurchasing.


Who doesn’t love to make their countertop look good? Maybe you do too. If so, then pick a sealer that can give the surface your desired look. But keep one thing in mind not all the sealers will enhance the look of your countertop, mostly the penetrating one.


What can be the worst outcome of having trapped moisture in your countertop right after sealing it? Any idea? Well, it can get cracked. Yup, you’ve heard it right. So, rather than replacing the entire countertop, we think choosing a breathable sealer will be a much more affordable option.


No matter how hard you try, you won’t be able to find any sealer that doesn’t contain a certain level of harmful chemicals. But when it comes to countertop sealers, you surely pick one up that you call the ‘least’ harmful.

But for that you’ll have to make sure that it’s totally food-safe and doesn’t contain any VOC or toxins. Another good option for you to be on the safe side is grabbing something that is made of natural elements mostly.

Ease of Application

We don’t know if you’re a DIYer or not. But if you are then we say bring a sealer home that won’t make you break a ton of sweat while being applied. The prime benefit of that is you won’t have to shed any bucks for hiring a professional anymore.

Benefits Of Using Sealer in Concrete Countertop

Benefits Of Using Sealer in Concrete Countertop

When was the last time you’ve bought something with zero benefits? Well, even if you have we don’t think you’re planning to repeat anything like that again, at least not for something like the countertop sealer. Don’t worry; investing in a sealer for your concrete countertop ain’t any waste and that’s because –

Saving From Mold And Mildew

If you start a competition on absorbing moisture, don’t get surprised if your concrete countertop comes first. After all, as a porous material, it has an amazing absorbing capacity.

But when you’re leaving it unprotected or without a seal, it’ll gradually start looking dump after sucking tons of water. And guess what will come up next? Yes, attacks of mold and mildew. On top of that, the surface will lose its actual appealing color too. But putting a seal on it takes out all these chances at once.

Maximizing Durability

Do you know what a sealer gets rid of in the first place? Yes, the gradual deterioration. But when it comes to concrete countertops this goes on a different speed as it’s something that you’re using almost daily.

So, when you put armor on it, what we call the sealer, it’ll ensure protection against all those regular hazards that can trigger damage on it. The list includes liquids, soap scum, salt, vinegar, cracks, stains, scratches, etc.

Color Enhancement

What do you think about hitting two birds with one stone? Well, that’s what will happen when you’ll use a sealer on your concrete countertop. Along with the above-mentioned benefits, it enhances the color and beautifies the surface to a certain extent, especially when you’ve got a countertop with a darker color.

How to Seal and Polish your concrete countertops

Top 5 Concrete Countertop Sealer Brands On The Market

At the end of the day, from pins to planes, no matter whatever a person buys, loves getting it from a renowned brand. Like that, the sealer industry has some giants too under the tag of ‘Top Brands’. So, here’s the top 5 brands that are simply ruling the world of countertop sealers.

1. Black Diamond Stoneworks

‘Starting from zero’ is probably a perfectly suited term for the Black Diamond. It’s tough to swallow that a brand that started with only five products now has expanded the number up to 30.

They’re mainly focused on sealing and cleaning products. And what to say about the product quality of this California-based? Their commitment to quality has simply done it all.


In the crowd of harmful chemicals, CLARK’S has somehow managed to keep it all-natural. So, when you’ll be looking for a brand that promotes natural ingredients more than anything, CLARK’S is a name you’ll find hard to avoid.

But they haven’t limited themselves with countertop care alone but have also expanded their wings in other different ways too including cast iron care, cutting board care, etc.

3. Miracle Sealants

If you want to learn how to roam with stars of success on your shoulder for more than three decades, then we’d say do it from Miracle Sealants. No matter what you need whether it’s for protection, cleaning, restoring, or enhancing your countertop, it can bring everything you can ask for.

4. Foundation Armor

When it comes to quality sealers, the one name you can never keep out of the topper’s list is Foundation Armor. Putting the quality first alone can’t take you ahead in the race and Foundation Armor knows that really well.

So, they’ve added some new feathers to the wings like delivering honest information, suggesting the best products along with providing industrial-grade products.

Frequently Asked Questions

What kind of damage a countertop sealer can prevent?

There are a ton of things that can lead you to a pretty messed up countertop and choosing the right countertop sealer is your only chance. By applying it you can keep your countertop away from problems like liquid, red wine, vinegar, salt, and of course, dirt.

What is the number of coats that are enough to seal a countertop properly?

Usually, two coats just work fine to create a protective layer on your countertop, but that totally depends on the absorbing capacity and nature of its surface. If it seems that two won’t work at its best, we say you go for the third one to be more sure.

How frequently the countertop requires resealing?

The duration is entirely dependent on the type of sealer. If you’ve chosen film-forming one, then you can relax for at least 5 years as you won’t have to give it a retouch. But the penetrating one can surprisingly extend the period up to 20 years.

Are all the sealers food safe?

Most of them are. But to be sure about that, read the labels properly and look if any toxic ingredients are mentioned there or not.

How to understand if the countertop needs resealing or not?

If you see any worn seal, dullness, or scratches, go for the resealing. But the easiest way to be sure about that is to see if the fallen water on it is not being beads anymore.

Final Words

If you’re going to ask us to make a list of the most important parts of the kitchen, then count it with closed eyes that the countertop will be on that list for sure. But the more useful it is, the more important it gets to protect it.

And what can do it better than the best concrete countertop sealer? After a ton of discussions on almost everything related to it, we believe you’re on the edge of getting your perfect sealer. Or let us guess! You’ve already got it, didn’t you?
