But that’s not the only reason for putting it on our list of toppers. Along with being food-safe, this stone sealer has the ability to protect the granite surface from anything like oil stains, water, and coffee stains.

Even if you’ve mistakenly dropped your favorite wine over it, there’s no way of getting a stain there.

By the way, its drying time has added an extra star. Just wipe it after spraying, and within just 20 minutes, you’ll have one of the most protected countertops right before your eyes.

Now it’s time for the wow factor. You might’ve imagined about sealer that is non-acidic, non-toxic, toxic, odor-free, and biodegradable.

Just because from the beginning you only see the word ‘granite’ again and again doesn’t mean it can’t go with the other granite surfaces.

Granite Countertop Sealer Buying Guide

If you have been thinking lately that none of the best granite sealers differs from the other, then sorry to say that you’re on the wrong track.

Not all of them can deliver equal performance or protection. You’ll have to deal with the hazard ‘variation’ again.

But this time, that ain’t going to be that much difficult. That’s because we’re about to tell you how you’ll find the best sealer for granite countertops in no time.

All you need to do is check out certain factors for the best results. Let’s get started, then.

Countertop Protection

If you list the reasons for using a granite countertop sealer, we bet this one will be on the top.

There’re lots of enemies on your countertop waiting to make it stain. So to save it from all of them, make sure the product has a powerful anti-stain formula.


You might love to see a lot of things on your countertop. But we don’t think a layer of toxic chemicals is on that list.

So, it would be best if you made sure the one you’re bringing in doesn’t have a pile of harsh chemicals that can cause you health issues. Moreover, they’re not good for the environment as well.

Food Safe

Every product that you get for your kitchen has to be Food safe. The same goes for granite countertops sealers as well. So, before you make the purchase, check if it’s food safe.

Ease of Application

The more accessible, the better — that’s the rule if you want something for direct application. It’s no different for granite countertops sealer too.

So, if you don’t want much of a hazard on that part, go for something that has fewer steps on the application for best results. And for some extra ease, pick one with a spray bottle.

Number of Coats

If the sealer has to be applied with too many coats, then be sure that is going to eat up a ton of your time.

Plus, it won’t be cost-effective as well. That’s because if you use it so many times, it won’t last as long as the single-coat one. So, try to pick a sealer that works with a single coat.

Preserves Natural Beauty

Who doesn’t love to keep things natural and new? We know you do too. This is why while grabbing a product to seal your countertop, you’ll have to prioritize its capacity to keep the natural beauty intact.

Otherwise, you might get a sealer but lose the visual appeal.

The Odor

Imagine every time you enter your kitchen; your nose tries to shrink in because of your granite sealer. If you don’t want that for real, do two things.

First, pick a sealer with low/no odor or a pleasant scent. Two, ensure proper ventilation while using it.

Time for Drying

How long can you keep yourself away from the kitchen? Because if you’re laying your hands on a sealer that takes 24 hours to dry, then forget about entering the place any sooner.

So to pass this hazard, pick a product that requires not more than a couple of hours to dry up.

Frequently Asked Questions (FAQs)

Question #1. What is the best sealer to use on a granite countertop?

Answer: As almost all the granite countertops sealers claim that they’re better than everyone else, it’s tough to find out who’s telling the truth. But performance speaks for itself. Depending on the type of performance you’re looking for, the best will vary for you accordingly.

We’ve reviewed the finest products in the market above, from where you can grab the heavy-duty granite countertop sealer without effort. They all are meant to deliver excellent protection and preserve the natural look of your countertop. So, picking any of them surely won’t be a regrettable decision.

Question #2. Should I seal my granite countertops?

Answer: Granite countertops can stain and face many issues with time, so sealing them is the best option here. Let us explain why you need to do this. At first, you want the granite surface to look good as new. So, sealing will save it from fading away on its appearance.

The second reason is that it’ll save the granite surface all the stains from water, spills, or acids. This way, you’ll not only remain headache-free but also will have the guarantee of having an entire countertop for a long time. But make sure that you’re renewing the sealing after a particular time.

Question #3. Can you permanently seal the granite?

Answer: Yes, it’s possible to seal the granite permanently, but it’s a hectic process. On top of that, you might need some expert help over there as well. So, you’ll have to lose some bucks there too.

On the other hand, using granite countertops sealers makes it so easy that you can do it all by yourself. And you won’t have to do that too frequently as well. So, this way, you can save yourself from both hassles and costs.

Question #4. How often are you supposed to seal granite countertops?

Answer: No sealers for granite countertops can save the granite surface forever. So, you need to renew them after a certain period. But you can’t predict the resealing time based on any specific duration. Some users think it’s better to seal every 6-12 months, but that’s not the case.

To be sure whether resealing is required, you better go for the water test. In this test, drop some water on the granite surface and see for 30 minutes if it’s penetrating the granite. You’ll see it getting darkened if the water goes in. If you see that happening, go for resealing.

Question #5. How do I clean my granite countertop and prepare it to apply the sealer?

Answer: The cleaning process of the countertop ain’t that hard, as it’s pretty much the same as regular cleaning. Take a clean cloth first. Make sure it’s a lint-free one because when using the sealer over the granite surface, you don’t want any lint to get stuck.

Now take the cleaning spray and spray it all over the countertop. Then wipe it thoroughly. Make sure there’s no dirt on the granite surface. Now let it dry, and once it’s dried up, it’ll be ready to apply the sealer.

Question #6. What happens if you don’t seal the granite?

Answer: Natural stones are usually quite sturdy and made for the long run. But that doesn’t mean they don’t need any maintenance and that maintenance part includes the sealing.

The first thing that’ll happen if you don’t seal the granite is that you’ll have to deal with the stains from different liquids. As kitchen countertops often come in touch with liquids like water, coffee, or juice, the granite surface is more likely to get stained.

Secondly, it’ll lose its natural look gradually. As everything fades away with time, so do granite countertops, especially when you don’t take care of them.

Question #7. How do you permanently seal granite countertops?

Answer: At first, clean the granite properly. Use the right cleaner and lint-free cloth to clean it thoroughly. Now let it dry. Once you’re done, wear gloves and ventilate the kitchen or bathroom. Now pick the seal and start applying it to the granite surface. Make sure it’s reaching all over the granite/stone surface properly.

Wait till the stone is absorbing the cleaner and sealer completely. Now, if the granite surface requires a second coat, go for it, and once you’re finished, wipe it properly. Don’t touch or put anything on the countertop for 48 hours.

Question #8. What is the best product to seal granite countertops?

Answer: Our recommendation is StoneTech BulletProof Sealer

Question #9. Is there a permanent sealer for granite?

Answer: The answer is yes. You can use a permanent bond sealant.

Final Words

If you take care, things sustain more than you expect them to. Like everything else, it’s the same for granite countertops as well.
