When it comes to applying a granite sealer on kitchen countertops, you need one that is food-safe and non-toxic. Fortunately, the Granite Gold Sealer is one of the best options on the market. 

The spray comes in a water-based solution that is easy to use and very convenient for regular applications. Spray it directly on the granite surface and wipe it off using a lint-free, soft cloth. Repeat the steps a couple of more times for the best results. 

Every ingredient in this granite sealer is non-toxic and non-acidic, so you don't need to worry about abrasive chemicals damaging the surface. Furthermore, the formula is pH balanced and efficiently forms a protective barrier. This protects the beautiful natural stone from stains, marks, scratches, and soil build-up.

Remember to allow the formula to cure for 24 hours after applying it. We also recommend waiting for at least 20 minutes between applications for the best results.

What Could've Been Better?

Our only gripe with this product was its long curing time. You need to wait for at least 24 hours for it to cure completely, during which time it is best to avoid using the countertop. This may be inconvenient for some users who need to use their kitchen countertops or other granite surfaces during the curing period. 



Pros

  • Easy-to-use spray bottle formula
  • pH balanced
  • Forms a protective barrier on granite surfaces
  • Affordable




Cons

In our opinion, the most attractive feature of this granite sealer is its promise of longevity. Sealing granite countertops and other surfaces can seem like a chore after a point in time, especially when it requires frequent resealing. 

With Miracle Sealants, we could sit back and relax for up to 2 years without worrying about when to reseal the surface. Not just that, if applied correctly, this can be effective for up to 20 years. Of course, we don't recommend waiting that long, just to be on the safe side. 

Moving on, we loved how easy it was to apply this product. Just pour it out on a safe, clean surface and apply it to your granite countertop. Allow it to cure for at least 3 to 5 hours before using the surface again. 

The formula has a unique UV protection feature that protects your granite surface from most weather elements.

What Could've Been Better?

Overall, this liquid granite sealer is an excellent purchase. That said, it can be slightly challenging to pour out from the container, especially since it does not come with an in-built sprayer. You need to be careful while pouring out its contents, or there is a risk of spillage and unnecessary wastage. 



Pros

  • Fast-drying solution
  • Does not leave white streaks
  • Adds gloss and shine
  • Long-lasting formula




Cons

  • Pouring out the contents can be tricky



Type: Penetrating | Coverage: Up to 1,000 sq. ft. | Suitable Surfaces: Granite, Marble, Slate, Limestone, Travertine | Application Method: Spray, Sponge, Roller | VOC Content: Low | Non-Toxic: Yes

Do you like your granite countertops to look clean and shiny all year round? Of course, doing this regularly requires time, effort, and investment. What if we told you there was a product that was easy to use, would clean and add shine to granite, and lasts for almost a year? 

It may sound too good to be true. However, we extensively tested the Rock Doctor Granite Sealer on various granite surfaces before reaching our conclusion. In our opinion, this is one of the best granite sealers on the market. 

Its ease of use makes it an ideal product for most. Furthermore, it comes in a handy spray bottle that covers an area of 100 square feet. All you need to do is spray it on your granite surface, let it sit for a few minutes, and wipe it off. 

The best part is, it not only cleans and protects but also adds a natural shine to the stone surface.

What Could've Been Better?

All said and done; this product is relatively short-lived. You will need to reapply the sealer at least once every six months or once a year. Although this isn't a deal-breaker, you need to keep it in mind when considering this product. 



Pros

  • Adds shine and gloss
  • Safe to use on kitchen countertops
  • Easy to use spray form
  • Provides a natural barrier




Cons

  • A short-lived formula that needs to be reapplied frequently

Moreover, this formula works efficiently to clean and seal any granite surface. You can use it daily to clean and maintain the surface or reapply the sealer once every few months when required. 

We recommend opting for the 1-quart bottle size as it is the most convenient one to use. One bottle will cover up to 300 square feet, so you don't need to worry about running out of formula.

What Could've Been Better?

The only minor drawback we noticed with this product was its relatively long curing time. As such, it took about eight hours to cure completely, which can be annoying for some users. However, you can apply the sealer at night and allow it to cure without disturbing the surface, enabling you to use it the following day. 



Pros

  • Convenient spray bottle formula
  • Environment-safe ingredients
  • 2-in-1 solution

Why Did We Like It?

Moving on to our next item, we have the Aqua Mix Sealer's Choice Gold. This granite sealer typically comes in a large bottle which is ideal for sealing and preparing large surface areas. You can use this product for sealing large granite countertops, floors, and other granite surfaces. 

Overall, the formula will cover almost 375 square feet and works ideally as a pre-grouting sealer. That said, pouring out the formula can be a messy affair since there is no spraying mechanism included. It is best to gently pour out the formula on a large surface and use a mop or cloth to spread it. 

One of the best things about the sealer is that it does not contain any ingredients that will provide a sheen or gloss to the granite surface. This is especially important when you want to pour the mixture on a floor, as slippery floors can be hazardous.

What Could've Been Better?

Unless you plan on using this formula on a smaller surface area, pouring it out should not be much of a problem. Since it does not come with a sprayer, nor does it feature a spout, pouring the formula can be slightly tricky. 



Pros

  • Long-lasting formula
  • Ideal for large surface areas
  • Versatile
  • Safe to use for kitchen countertops as well as floors




Cons

What Could've Been Better?

While the formula offers excellent cleaning and polishing capabilities, it is best used as a sealer. Apply the formula directly on your granite surfaces and allow it to sit for a couple of minutes. Wipe it off gently using a clean, soft cloth. Repeat this once every six months for the best results. 

Although this large jug was made to seal extensive granite surfaces, you can use it on smaller surfaces like kitchen countertops as well. Purchase the high-quality trigger that enables you to spray the formula directly on countertops and other surfaces. Apply the same process and wipe it off gently after a few minutes.

What Could've Been Better?

Our only gripe with this item was its heavy fumes and odors. As such, it is best to properly ventilate your rooms when using the sealer. Moreover, ensure that you keep all your doors and windows open, as well as turn on the fans. The odor should dissipate naturally within a few hours.

Buying Guide For The Best Granite Sealer

With that, we have finally reached the end of our comprehensive list of recommendations. Hopefully, you have already found the right product for your needs. However, if you haven't decided yet, no worries. 

In this section, we will discuss some of the most important things to consider when purchasing the right granite sealer for your home. So, let us begin!

Sealer Form

Although we have primarily added liquid sealers to our list, you will find several other forms in the market. These vary from aerosol sealers to wax and other polishing compounds. 

As such, applying liquid and aerosol sealers is an easier option. Wax and polishing compounds typically require some elbow grease, so we do not recommend this if you have back or shoulder problems. 

Moreover, liquid sealers penetrate the natural stone surfaces much more efficiently, making them a better option for most users. You can also consider aerosol cans if convenience and fast coverage are of importance.

Longevity

You may have realized that different granite sealers come with varying longevity options. While some sealers guarantee to last for at least a year or more, others may require reapplication more often. 

There is no right or wrong answer to how often you should seal granite surfaces. Surfaces that are used frequently may require more frequent application of sealers than others. However, keep in mind that sealing a granite surface requires a bit of effort, which you should be prepared for. 

It is vital to remove all items from the granite surface before you begin. Furthermore, you should only seal the surface after having thoroughly cleaned it. In this case, it may be easier to opt for a 2-in-1 granite cleaner and sealer if you want to make the job slightly more manageable.

Curing Time

Any granite sealer requires a certain amount of time to cure before you can use the surface again. While most products require a couple of hours, you may come across certain sealers that need to be left undisturbed overnight or even for 24 hours. 

If you aren't in a hurry to use the surface, you may consider opting for heavy-duty granite sealers, which require more time to cure. However, if you need to use the granite surface and cannot afford to leave it undisturbed overnight, it is best to opt for formulas that cure within a couple of hours.

Glossy Vs. Matte

Several granite sealers in the market promise to add shine and gloss to the surface after curing. Theoretically, glossy granite is much more aesthetically pleasing and appealing than matte surfaces. 

That said, it is not always the safest option for all surfaces. For example, opting for glossy granite floors may not be safe, especially if you have children, pets, or elderly people using the floors. The slippery surface may cause accidents and injuries which could have easily been avoided. 

Depending on your needs and tastes, it is imperative to check the finish of a granite sealer before purchasing it. Sealers that add sheen can be ideal for kitchen countertops and other smaller surfaces, but not for bathrooms, tiles, and floors.

Granite Sealers FAQ's

  • Why should I use a granite sealer?

    Granite is a porous material that can easily absorb liquids and stains. Using a granite sealer helps to create a protective barrier on the surface, making it resistant to stains and easier to clean.

  • How often should I apply a granite sealer?

    The frequency of applying a granite sealer depends on various factors such as the quality of the sealer used, the level of usage, and the porosity of the granite. Generally, it is recommended to reapply the sealer every 1 to 3 years for optimal protection.

  • How do I apply a granite sealer?

    The application process may vary depending on the specific sealer, so it’s important to follow the manufacturer’s instructions. In general, you’ll need to clean the granite surface, apply the sealer evenly with a brush or cloth, let it penetrate for the recommended time, and then wipe off any excess sealer.

  • Can I use any sealer on my granite countertops?

    It is recommended to use a sealer specifically formulated for granite or natural stone surfaces. These sealers are designed to penetrate the pores of the granite and provide effective protection without damaging the stone.

  • Will a granite sealer make my countertop shine?

    Some granite sealers may enhance the natural shine of the stone, while others provide a more matte or natural finish. It’s important to choose a sealer that matches your desired aesthetic preference.

  • Can a granite sealer prevent all stains?

    While a granite sealer provides a protective barrier, it may not be able to prevent all types of stains. It is still important to clean up spills promptly and avoid using harsh or acidic cleaners on the surface to maintain its longevity.

  • Can I use a granite sealer on other types of natural stone?

    Some granite sealers can also be used on other types of natural stone surfaces such as marble, travertine, and limestone. However, it’s essential to check the sealer’s instructions and suitability for the specific stone before application.
