8 Best Granite Sealer Of 2022 – Reviews & Buying Guides

8 Best Granite Sealer Of 2022 – Reviews & Buying Guides

Granite is more than just a beautiful stone with different textures and colors. This beautiful stone is also heat-resistant and scratch-resistant. Maintaining granite countertops is essential, however. You should seal granite regularly to keep it looking pristine.

While you may think you can wipe any spills from your countertop, granite is porous. As spills accumulate over time, they can damage the stone. Granite countertops can be easily sealed if you wish. A granite sealer will not only protect your countertop, but some will also polish, clean, and sanitize it. If you compare it to the cost of replacing your counters, it’s a simple solution.

By comparing all 8 granite sealers in our review, you won’t have to compare each one painstakingly yourself. According to our comparison table, the protection duration of the products varies. Those sealers that can polish and clean that we previously mentioned will also be obvious.

Our comprehensive granite countertop buyer’s guide makes granite countertop maintenance easy as well. The discussion of granite types and sealants did not end there. You also learned what to keep in mind when sealing your granite surfaces. If you’re interested in visiting that section, click here for our review.

1. Black Diamond Stoneworks Granite Sealer

You can feel confident that the process will be straightforward with the Black Diamond Stoneworks Granite Sealer. A simple spray bottle comes with this product. Using a spray bottle makes applying the granite sealer convenient and fast.

After applying this product, a hard finish will be left behind. These are designed to resist scratches and scuffs. In addition, they are non-corrosive and non-toxic.

You can also make granite surfaces particularly easy to clean by doing this. The newly installed surface is hard enough to be easily cleaned with a damp cloth. Ultimately, this will save you a lot of time and trouble.

The granite sealer doesn’t have an issue with this. The water-based formulation does not contain harsh chemicals. There is a lemon scent infused into this high-quality granite sealer.

This granite sealant can therefore be used on kitchen counters as well as bathroom surfaces. Because the formula penetrates deeply into the granite, it provides greater resistance to stains. No matter how frequently the surface gets wet, the water will be held back.

After drying, the product has a slightly cloudy appearance. Consequently, it may damage surfaces such as granite countertops. If necessary, you can change your plan after four months to another option.

You may also like:

  • Spray bottle for convenience.
  • Surfaces safe for food.
  • Not toxic or corrosive.
  • Only lasts a few months.
  • Dryes a little cloudy.

2. Granite Gold Water-Based Sealing

Although many granite sealers are effective, they often contain harsh chemicals. In addition to having an unpleasant smell, these cleaners are not recommended for use on food preparation surfaces. When you choose Granite Gold Sealer Spray, you don’t have to worry about this.

Despite its non-toxic, non-acidic, and biodegradable nature. This means it can be applied to any surface. Bathrooms, kitchens, and just about anywhere else can all benefit from this product.

When used, this water-based product will not emit unpleasant odors. This formula contains no acids, so you won’t suffer from discoloration. You can use this product on most types of stone surfaces.

Among granite sealers, this is probably the easiest to use. Simply mist the product onto the desired area and let it dry. The second coat can be applied 20 minutes after the first one has dried. When fully dried, this product forms a hard surface that inhibits water from penetrating the granite.

Nevertheless, all of this convenience comes at the cost of convenience. Granite Gold Sealer Spray will only last you about a year. It is also possible that you will have to apply several coats of sealer in order to fully protect granite.

  • Dryes within twenty minutes.
  • Contains no toxic odors.
  • Durable and hard finish.
  • Has a one-year shelf life.

3. HMK S234 Stone Impregnating Sealer for Granite

HMK Stone Impregnating Sealer for Granite
HMK Stone Impregnating Sealer for Granite

Again, this is a solvent-based sealer for granite. Solvents penetrate further than water or oils, so this sealer penetrates much further. This results in a thicker finish that is more resistant to damage.

The one here does not enhance the natural appearance of the stone. The gloss doesn’t even add that much to the surface. Those who are drawn to the natural look of unpolished stone may enjoy this product. The material is also vapor-permeable, which is ideal. This sealer provides an easy way to get rid of the moisture trapped in the stone.

Although it’s safe for floors, it’s also tough enough for food prep surfaces. A little credit goes to the manufacturer for striking a balance between two extremes. In addition, I like this sealer’s requirement for only two coats. While some granites are more absorbent, many of them can be applied in two coats. That could be because of the product’s thick and goopy consistency.

I do see some problems as well, however. The stone won’t be slick or shiny, so some people may not like the price. A surface must be clean and dry to allow the sealer to adhere. The label says the surface shouldn’t have been in contact with liquid for at least 24 hours. The drying time for this one is from 2-4 hours, and the curing time is about 48 hours. Though it may be somewhat inconvenient, the results are definitely worth the wait.

  • Permeable to vapour.
  • Food preparation surfaces safe.
  • Most paints only need two coats.
  • Cleans and dries the surface thoroughly.

4. Miracle Sealants 511QT6 511 Impregnator Sealer

We’ll examine one of the best granite sealants. Miracle Sealant’s 511QT6 511 Impregnator Penetrating Sealer (QT6) guarantees twenty years of protection for granite. The product penetrates deeply into stone surfaces so water and other liquids cannot accumulate.

Both indoors and outdoors are suitable for this model. The granite it covers is up to a thousand feet long. Moreover, the formula is non-toxic, so it can be used on surfaces such as granite countertops for food preparation.

You may also like:

A barrier is created once the product is dry. This material is water- and oil-resistant. We are so confident that it will last that we offer a twenty-year warranty.

You can also use this product on a variety of other surfaces in addition to granite. Some of those include natural stone, ceramic tiles, and slate. Using the product for grout applications may not be as effective, so extra care is needed.

This product has a somewhat strong smell when first opened. The smell dissipates quite quickly, but it may not be pleasant at first. In case of indoor use, the room should be well ventilated.

It’s important to take extra precautions when applying this product. The result would likely be discoloration or smudging if applied incorrectly. Still, your coverage is twenty years, so make sure you choose wisely.

  • Ideal for food prep areas.
  • Water and oil resistant.
  • User-friendly.
  • Initial smell is strong.

5. Rock Doctor Granite Sealer

In addition to granite, grout, and other natural stones, Rock Doctor 35106 Granite Sealer is exceptionally effective. It comes in an easy-to-use spray can that allows for even application. This product has more to offer, though. Here’s what you need to know!

When it comes to grout and granite sealers, you can find them here if you are seeking them. Using the Rock Doctor 35106 Granite Sealer, the grout will be effectively protected from moisture, stains, and mold growth.

Natural stone, granite, and other rocky surfaces can be treated with one bottle, making it very economical. It also protects countertop and stone surfaces from corrosion and prevents them from deteriorating in quality. They prevent moisture and grime from accumulating, resulting in a surface that looks fresh over time.

The sealer is also simple to operate. Simply remove the cap and spray the cleaner onto the surface to be cleaned. Let the surface dry for 30 minutes, then remove the residue.

I have used this product for quite some time and am quite happy with its performance. Nevertheless, there is a minor flaw. Black granite surfaces cannot be cleaned effectively with this product, and it does not remove water stains.

  • Grout is cleaned of mold.
  • Spray can for easy use.
  • Worked on several surfaces.
  • Black granite is less effective.

6. Tenax Granite Sealer

It’s important to consider the process if you’ve never used a granite sealer before. You don’t want to ruin your beautiful granite countertop by making a mess. When you use the Tenax Granite Sealer, this problem won’t arise.

Simply dab some granite sealer on a cloth and wipe it off. Your choice of cloth can include an old t-shirt. Allow the product to absorb into your granite surface. The formula is so powerful that it should last a lifetime. The sealer will be the last one you need to use.

You need only apply one coat of sealer to granite to protect it. That’s why it’s a time- and cost-effective solution. Moreover, it dries so fast. For 24 hours, you may not be able to experience water resistance. In the bathroom, granite surfaces might be an issue if you apply the product there. Due to the initial strong odor, you will also need to make sure that you ventilate the area well.

  • Dryes completely invisible.
  • Requires only one coat.
  • Improved moisture resistance.
  • Effectiveness lasts for 24 hours.

With this granite sealer, you will get good value at a great price. For those who want to save money when doing a large or medium project, this sealer offers several advantages. Let me begin by mentioning that this sealer is one of the least expensive on the list.

Granite sealer offers excellent coverage, so as long as you are careful, one quart should last you a long time. The results of sloppy application techniques can lead to some sealer waste, but it is easily avoided.

Another really cool feature is that you only have to apply the sealer once. As opposed to most stone sealers, this one is easy to apply and forget about. Other sealers require that you mark your calendar to remind you to reapply. Probably you do not need to take on another obligation, especially one that is completely optional.

Using a scrap piece of cloth is said to be the easiest way to apply this granite sealer. If you don’t have a scrap of fabric to use, you can use a stained T-shirt. As a result of its rapid drying time, the process is much easier. Your surface is ready to buff and polish within ten minutes.

In addition to fast-drying, you can do large surfaces (like floors) in little time with this formula. Despite the fact that this granite sealer dries quickly, its water-repellent properties will not manifest for 24 hours.

The most detrimental aspects of this sealer are its harsh and toxic properties. The sealer has a strong odor, which requires that you wear some kind of respiratory protection when you use it indoors. This sealer is also causing concern regarding its safety on kitchen countertops.

Due to their harsh properties, granite sealers are classified as hazardous materials, which may lead to trouble when ordered by mail. While shipping costs may vary depending on where you live, shipping costs are typically higher everywhere.

  • Coverage is excellent.
  • Cheaper than most others.
  • Quickly dries.
  • Limitations in shipping.

8. TriNova Granite Sealer

If you want to preserve granite surfaces, simply sealing them isn’t enough. As well as protecting your granite now, you need to protect it in the future. Keeping your granite surfaces clean will help to ensure their durability.

We were able to successfully meet the challenge with TriNova Granite Sealer & Protector. The spray bottle dispensing this product makes it easy to use. You can direct the product precisely where you need to seal and protect, thanks to its unique design.

Granite pores allow the product to penetrate deeply into the surface. This ensures that the joints will be completely sealed. It also forms a layer that prevents water and oil from penetrating the granite.

Although the spray bottle is the most convenient way to apply the product, you can also use a damp cloth. Adding the protective layer to your product will produce a high shine. The protective layer is non-stick once it dries, ensuring your granite will be easy to keep clean.

You will be able to achieve a clear surface by buffering after applying granite sealer. However, you will discover that this is a very simple and quick process. With this product, a fully protective surface is created that will help extend granite’s life.

  • Grout-safe.
  • Provides protection.
  • Surfaces for food preparation.
  • Buffering is needed after application.

Buying Guide: Best Granite Sealer

There are different granite sealers, so don’t assume they’re all alike. Variations can occur in the strength, active ingredients, and even quantity of the product. Choosing the right granite sealer involves considering several factors.

The Number of Coats

A longer process will ensue if you need to apply for more coats. A number of coats will elevate the cost of the product as well. Products that work with just one coat are quicker and more cost-effective.

Ease of Use

Your product choice must be easy to apply and as quick as possible. Products that can be sprayed are ideal. Using these products is as simple as spraying them onto the desired product and letting them work.


It is important to avoid breathing in toxic chemicals while applying granite sealer. There are a number of organic and water-based products available today. The formulas are chemical-free, so your lungs and the environment are safe.


There are some granite sealers that have a strong and somewhat acrid aroma. It is therefore important to ensure the area where you apply them is well-ventilated. Nevertheless, there are products available that are odorless and even have pleasant scents.

Food Safe

When installing granite countertops, it’s important to ensure that they are food-safe. The countertop will not leach chemicals when your food touches it.

You may also like:

Drying Time

Drying certain products may take up to 24 hours. If you plan to use your granite countertops later on in the day, this may affect them. A few products dry quickly and provide complete protection within a few hours.


One last consideration is how long the chosen product will protect your granite. You may need to reapply for some products every couple of months. There are other products that provide long-lasting protection.


It is important to consider the durability of a sealer when choosing one for granite. Granite sealers should be both water and oil-resistant, as well as suitable for use both internally and externally. Make sure whichever sealer you choose will be durable enough.


Granite stones are not all the same. Maintenance differs for different kinds of countertops based on the kind of stone you have. In our buyer’s guide, we explained how to distinguish granite based on color or grade. Particularly when it comes to sealing, it is important to understand the surface’s density and water-repellency.

Your stone can be tested quite easily. Pour some water and then wait for it to form into a dark area to see how long it takes. It is imperative to test the water before use if you do not want to waste time and products. For our top choice, we recommend the StoneTech BulletProof Sealer. This sealer is more expensive compared to most in this review, but its effectiveness cannot be denied. As well as protecting against stains, this sealer allows easy application with no irritating, harmful VOCs.

In addition, you can also use products like CTP and Supreme Surface to clean and polish. Both are made by the same company, and choosing one is a matter of personal preference. In addition, we recommend TriNova if you need a quick-apply product.

You shouldn’t be afraid of granite countertops in general. Several products require repeat applications every six months. Then you can unravel your newly-sealed granite top every time afterward, giving you a thrill.


Does sealer darken granite?

Sealers tend to darken the stone just slightly, but they shouldn’t make a noticeable difference. There is usually no discernible difference between the two. As long as a sample of unfinished stone is not placed side-by-side with the counter for comparison, little difference will be noticed.

When applying the sealer for the first time, you may notice that there is a change in tone, but there is no need to worry. The finish should lighten within 48 hours of drying and curing. Surfaces with texture will show the effect more strongly, while smooth surfaces will not.

Can sealer make granite look wet?

It’s true that some sealers can cause granite to appear wet. Their gloss is enhanced by adding a substance called a gloss enhancer. Reflecting light makes the stone’s surface shiny with a gloss enhancer. Brightening colors can also be achieved this way.

Sealers sometimes contain wetting agents as well. Wetting agents help spread out water evenly on surfaces. Wetting agents help the sealer create a damp appearance on granite when combined with gloss enhancers. The fact that not all sealants contain gloss enhancers or wetting agents is important to note.

How Long Does It Take To Seal Granite?

You need to seal granite for varying amounts of time depending on the product that you use. The cure time for some products can reach 72 hours, but for others, there is no wait time at all. You will also have to factor in the area you are covering, the type of product, and the tools you are using. Application times can range from 15 minutes to several hours, depending on various factors.

Can granite countertops be protected without sealing?

Sealants formulated to penetrate deeply into the stone surface offer the best protection for granite and other stone countertops. By making a surface that repels water, you are preventing liquids from reaching the stone. There is no way you will get the same level of protection unless you use another filler.

Is oil suitable for sealing granite?

Sealing granite with oil is not possible. People usually use oil for wood, but not stone. Besides dulling the look of granite, oil also promotes mold and mildew growth. Oil should be replaced with granite or stone sealers. Granite sealers are specially designed for sealing stones.

Before sealing granite, what do you use to clean it?

Before sealing your granite countertops, clean them thoroughly with a granite cleaner. If you are going to apply sealer, make sure the surface has been thoroughly cleaned 24 hours before you apply it. Avoid using harsh chemical cleaners or acidic cleaners like lemon, vinegar, or bleach.
