Best Granite Sealers 

To help you find the right sealer for your granite surface, here is the list of the 6 best granite sealers.

1. TriNova Granite Sealer – Best Overall

If you are looking for a sealer that not only tightly seals the granite surface but also forms a protective film over it, the TriNova Granite Sealer is worth considering. What’s more, it seals and protects not just granite but also marble, slate, limestone, quartz, and soapstone.

The TriNova Sealant is the one-stop solution for sealing many surfaces. It comes in an 18-oz bottle for quick application. Use it on kitchen countertops, bathroom tiles, or floor tiles for effective sealing.

All you have to do is spray it on the surface and wait for a minute before wiping it dry with a microfiber cloth. Leave it on for an hour or so, and you’re good to go. It’s that simple!

Now, we will move on to its working mechanism. The sealer uses a mixture of polymers that enter the stone’s surface, providing a barrier that doesn’t let stains seep. As a result, stains do not become permanent. Not just that, the sealer also adds gloss to the surface and improves its natural look.

Besides, if you’ve wasted hours trying to remove the dregs that develop between the bathroom tiles to no avail – you’ve got a solution in the form of this sealant.

The only downside of this product is that it needs to be re-applied frequently. Although it works very well for eliminating stains from countertops, it is not as useful for watermarks and doesn’t repel water as well as we expect it to.

Volume: 18 Fl Oz | Scent: Unscented | Form: Spray | Special Feature: Biodegradable | Coverage: 75 sq ft/bot

2. Miracle 511QT6 Granite Sealer – Best Coverage

If slippery surfaces have you watching your steps at all times, then the 511QT6 Sealer from Miracle Sealants will come to the rescue. The product has a wide application and can work on stucco, travertine, marble, slate, granite, and even ceramic tiles.

Not just inside the house, it also works outside on the driveways and patios.

The 511 Impregnator from Miracle Sealants can cover an area of 1,000 sq ft per quart, making it a cost-efficient purchase. Besides, it covers numerous surfaces, from ceramic tiles to terrazzo.

Therefore, you no longer have to worry about buying different sealants for separate surfaces in the house. The versatility of the product allows it to work on countertops and bathroom tiles and even facilitates exterior application.

Yes, you read that right! No separate sealants for house exteriors! The 511 sealant is excellent for the stones and tiles in the courtyard and driveway.

Additionally, the product seals dense pores and removes moisture from the surfaces, giving them a glossy look and creating a protective shield. The shield doesn’t let water seep through, and the surface remains free of stains.

Finally, we particularly liked how it hardens the surface without altering the original look.

You’ve to be quick while applying this granite sealer. Remember to rub it thoroughly for 3 to 5 minutes after application. If you let the product dry on the surface, it leaves behind a grey cast that makes the surface look dull. So, be alert!

Volume: 32 Fl Oz | Scent: Strong Odor | Form: Liquid | Special Feature: Impregnator Sealer | Coverage: 1000 sq ft/qt

3. Granite GG0036 Gold Sealers – Best Budget Friendly

Founded in the 1950s, Granite Gold is a family-owned company with a history of producing unrivaled stone maintenance products. The GG0036 Sealer is no exception and is useful for stone, ceramic, and granite surfaces.

It is non-toxic and contains no ammonia – making it the ideal product for kitchen countertops.

If you’re apprehensive about applying chemical sealants in food preparation areas, you’re in for a surprise. The Granite GG0036 Gold Sealer is a non-acidic product that is 100% free of any toxic chemicals.

It is a water-based solution in a spray bottle and can be directly sprayed onto the surface. It can protect the kitchen worktop from coffee, wine, and oil stains, which are very difficult to remove, by creating a preventive barrier.

Not just granite, the sealant protects natural stone surfaces against stubborn stains, marks, and unwanted build-up.

Furthermore, it is not corrosive to natural stone and doesn’t take away its natural shine. Unlike some other chemical sealants with a strong odor, the Granite Gold Sealer has a mild citrus odor that is not just pleasant but also safe.

Also, it is not expensive at all, so if you were under that impression, we’re glad to have proved you wrong.

One minor gripe we had with this product was the number of applications it requires. Usually, you will need anywhere between 2 to 3 applications at 20-minute intervals to ensure perfect sealing.

Additionally, it needs to be left for one whole day before you can polish it. So, it tests your patience, but the results are fantastic.

Volume: 24 Fl Oz | Scent: Travertine | Form: Spray | Special Feature: Water-based sealer | Coverage: 100 sq ft/bot

4. Black Diamond Stoneworks Granite Sealer  

Now that we’re halfway through our list, here is another excellent product for your consideration. The Granite Plus from Black Diamond Stoneworks uniquely combines granite sealer and cleaner. It comes in a variety of sizes – from one quart to a gallon.

So, you can pick a size as per your requirements.

If you thought an effective granite sealer was going to cost a fortune, think again. The Granite Plus Sealer from Black Diamond Stoneworks is affordable and provides superior surface protection.

It works smoothly on travertine, marble, limestone, and granite by sealing and cleaning them meticulously. As a result, the kitchen top will always be free of oil, coffee, wine, and food stains.

The smell is not overbearing, and the sealant is free of toxic chemicals, making it safe for food surfaces.

Besides, it has anti-corrosive properties, and you can use it without worrying about the elegant stone surfaces in the house being corroded. It not only protects the surface but also lends an attractive shine to it.

Also, if you need a solution for everyday kitchen cleaning, this one is it. Just a few sprays and the kitchen will be spick and span in no time.

We were slightly disappointed with the sealing abilities of this product. Although it is an excellent cleaner and leaves a polished surface, it does not adequately seal the porous surface, thus exposing it to stains and grime build-up.

Volume: 32 Fl Oz | Scent: Mild Chemical Odor | Form: Spray | Special Feature: Hypoallergenic / Acid Free | Coverage: 120 sq ft

5. Rock Doctor 35106 Granite Sealer

The 35106 water-based granite sealer from Rock Doctor works extraordinarily well on grout, granite, and other natural stones. It comes in a convenient, user-friendly spray can that makes even application possible.

However, there is more to this product. Keep reading to know all the deets!

If you’re looking for an effective grout and granite sealer, you’ve come to the right place. The Rock Doctor 35106 Granite Sealer seeps deep and works with the grout, thereby safeguarding it against moisture, stains, and unwanted mold buildup.

Moving on, one bottle will suffice for 100 sq. ft. of natural stone, granite, and other surfaces, making it a cost-effective solution.

Besides, it builds a protective layer over the countertops and stone surfaces and doesn’t let them deteriorate in quality. As a result, they always keep the moisture and grime accumulation at bay, and the surface looks fresh over the years.

Furthermore, the sealer is very easy to use. Just remove the cap and spray it onto the surface that needs to be cleaned. Remove excess residue and give it 30 minutes to dry off, and the surface will be ready for use.

For best results, re-apply the sealer every six months.

We’ve had this product for a considerable length of time now and are quite pleased with its efficacy. However, it has a minor flaw. It doesn’t work effectively on black granite surfaces and doesn’t remove water stains and discoloration.

Volume: 1.25 lbs | Scent: Mild Chemical Odor | Form: Liquid | Special Feature: Granite Sealer-Aerosol | Coverage: 100 sq ft/can

6. Aqua Mix Sealer’s Choice Gold Granite Sealer

If tough-to-remove stains on expensive granite have you worried, this water-based formula will provide the ultimate solution for all your woes. It can clean large surfaces with no hassle and is a favorite among buyers for its ability to be used both indoors and outdoors.

The Aqua Mix Granite Sealer is a perfect protectant for stone, grout, granite, and tile surfaces. It removes stains and etches and lends durability without compromising the natural sheen of the surface.

In addition to that, it has a low VOC and is specially designed for areas of food preparation and serving. Besides, it claims to last up to 15 years and is resistant to mold and mildew.

Not just kitchen areas, if you are looking for a good sealer for around the swimming pool, this one should be your definitive pick. It works on low-porosity surfaces and penetrates optimally, thus sealing them and providing sufficient stain protection.

Additionally, it also makes them slip-resistant.

Moving on, it works on unglazed tiles, natural stone surfaces, concrete, brick, and grout – making it a versatile sealant for both exterior and interior surfaces.

Lastly, the sealer doesn’t tamper with the surface’s natural finish.

We noticed a white film forming on the surface. Usually, this happens when the product is not wiped immediately and dries on the surface. However, it can always be scrubbed using a nylon pad and chemical scrub.

Also, even though the sealer is quite adequate, it doesn’t come in a spray bottle and can be difficult and messier to pour.

Buying Guide For The Best Granite Sealer


When it comes to choosing the best granite sealer, there are several factors to consider. Granite is a popular choice for countertops and other surfaces due to its durability and beauty, but it does require proper maintenance to keep it looking its best.

Granite sealers provide an extra layer of protection against staining and discoloration, and can also enhance the natural beauty of the stone.

To ensure you choose the best granite sealer for your needs, it is important to understand the different types of sealers available, how long they last, and how they should be applied.

This guide will provide an overview of what to consider when choosing the best granite sealer for your countertops or other surfaces. 

Size


The size of the granite surface you are sealing is an important factor when selecting a granite sealer. If you are sealing a small surface, such as a countertop, you may want to opt for a penetrating sealer, which will provide a deeper level of protection.

Penetrating sealers can also be used on large surfaces, such as floors or walls, but the coverage will be less effective. For larger surfaces, an enhancing sealer may be a better option, as it provides better coverage and enhances the natural beauty of the stone.

Types


When selecting a granite sealer, it is important to understand the different types available and how they work. The three main types of granite sealers are penetrating, enhancing, and topical. 

  • Penetrating Sealers
    Penetrating sealers are designed to penetrate the surface of the granite, creating a barrier that prevents liquids and other substances from staining or discoloring the stone.

    Penetrating sealers are the most effective option for long-term protection, but they can be more difficult to apply than other types of sealers.
  • Enhancing Sealers
    Sealers are designed to enhance the natural beauty of granite by creating a glossy finish. These sealers are easy to apply, but they do not provide the same level of protection as penetrating sealers.
  • Topical Sealers
    Topical sealers are designed to create a barrier on the surface of the granite, preventing liquids and other substances from penetrating.
    These sealers are easy to apply, but they are not as durable as penetrating sealers and will need to be reapplied more frequently.

Duration


The duration of protection provided by a granite sealer is also an important factor to consider. Penetrating sealers typically provide the longest-lasting protection, while enhancing and topical sealers will need to be reapplied more frequently.

When selecting a sealer, be sure to read the manufacturer’s instructions to determine how often it should be applied.

Odor


When selecting a granite sealer, it is important to consider the odor that the sealer creates. Some sealers can produce an unpleasant odor when applied, which can be difficult to remove. Be sure to read the manufacturer’s instructions to ensure the sealer you choose is odor-free.

Application


The application process for a granite sealer can vary depending on the type of sealer you choose. Penetrating and enhancing sealers typically require more preparation, such as cleaning with a granite cleaner before applying the sealer.

Topical sealers are easier to apply, but may not be as effective as the other types of sealers.

Versatility


Another factor to consider when selecting a granite sealer is its versatility. Some sealers can be used on a variety of surfaces, including countertops, walls, and floors, while others are designed for use on specific types of surfaces.

Be sure to check the manufacturer’s instructions to ensure the sealer you choose is suitable for the surface you are sealing.

Quantity


The quantity of sealer you need is also an important factor to consider. Most granite sealers are sold in large quantities, such as gallons or quarts, and the amount you need will depend on the size of the area you are sealing.

Be sure to measure the area you are sealing before purchasing a sealer to ensure you purchase the right amount.

What are the benefits of sealing granite?

Sealing granite provides a layer of protection against staining and etching, as well as enhancing its durability and shine. It also makes cleaning granite countertops easier and helps to prevent bacteria and other contaminants from coming into contact with the surface. 

Is it possible to use granite sealer on other countertop materials?

Most granite sealers can be used on other types of natural stone, including marble, sandstone, soapstone, limestone, and travertine. However, don’t use granite sealer on wood, metal, tile, quartz, or laminate countertops.

Yes, granite sealer is considered safe for use. It is made up of non-toxic ingredients, and when applied properly, does not pose a health risk. 

What effect does granite sealer have on the lifespan of a countertop?

Granite sealer helps to extend the lifespan of granite countertops by protecting them from staining and etching. It also makes them easier to clean and helps to prevent bacteria and other contaminants from coming into contact with the surface. 

What are the pros and cons of using granite sealer?

The pros of using granite sealer include protection against staining and etching, enhanced durability and shine, easier cleaning, and protection against bacteria and other contaminants. The cons include the need to regularly reapply the sealer to maintain the protection. 

How frequently should granite be sealed?

Granite countertops should be sealed every 1-3 years, depending on the amount of use and exposure to liquids and other contaminants. 

What are Volatile Organic Compounds (VOCs) and how can I protect myself from them?

Volatile Organic Compounds (VOCs) are chemical compounds found in some liquid sealers, solvents, and paints. To protect yourself from exposure to VOCs, use sealers and paints that are low or zero VOC, wear protective clothing when applying sealers and paints, and ensure that the area is well-ventilated.
