5 Best Marble Sealer Review
Let us first look at some great options from the current market for the best marble sealers for you to pick from.
#1. Rocklinite Labs Tuff Duck Marble Sealer Review
- Maximum protection for Granite, Grout, Marble, Travertine, Limestone, Slate, and even Concrete!
- Penetrating sealer will not affect the natural appearance of your delicate stone tile
- Twice the active ingredient as StoneTech to ensure proper protection with a single coat
- Protects up to 5 years on interior surfaces and 3 years on exterior surfaces
- Non-Acidic formula provides coverage for up to 200 square feet
- Usable on many surfaces besides just marble.
- Can be used on the delicate stone without damaging the pattern or appearance.
- Covers over 150 square feet with just a single quart.
- Good for use on both interior and exterior marble surfaces.
- Some surfaces may need annual reapplication to ensure proper durability.
We are kicking it off with the Tuff Duck Sealer by Rocklinite Labs, which can be used on a number of surfaces, including marble, granite, and grout. It also offers maximum protection when applied on limestone, slate, and even more porous surfaces like concrete.
When used on more delicate looking or intricate tiles (such as ones made of stone), this sealer penetrates the surface but does not ruin the tiles’ appearance.
Because of the higher quantity of an active ingredient being in this formula, the sealer protects surfaces well enough with just the first coat. Though, of course, two coats or more are recommended for general durability.
The sealer does not contain any acids, so it will not dissolve natural tiles or their detailing. This is also due to it being a water-based formula. And you can easily cover upwards of 150 sq. ft. with a single quart bottle of this.
Coming to longevity, when applied on exterior surfaces, the sealer can last for three years before starting to wear off. But it holds up really well for about five years on interior surfaces due to lack of interference from the elements.
Although, if you really want it to last, you might want to do a coating every year before it has a chance to start wearing out.
Verdict: A fabulous high-quality marble sealer that could work on many other surfaces and protect perfectly. Try it out for yourself!
#2. Tenax Marble, Granite, Stone, and Concrete Sealer Review

It will also be great for someone who does not have any experience working with marble sealers because they can get used to the feel of using them and also figure out drying and curing times for different formulas.
The Ager sealer is used for enhancing the natural color of the stone or marble. It is able to make the color of the marble pop and look richer than it originally is, while also filling in any dents or scratches.
Next up, the Hydrex sealer works great when you are not looking to change the color of your marble in any way. It also will not give your marble a wet look but will help it keep its original appearance by giving it protection against the outside environment.
The Proseal sealer and Quartz toner are also similar to the first two since the former does the job of sealing the marble and protecting it from moisture, oil, and water. And the latter enhances the color of the marble and gives it a smooth and wet look.
Verdict: A great one to try for different marble surfaces and different sealer needs, or if you just want to get used to the marble sealing process.

This high-quality marble sealer from StoneTech is the perfect option for natural, porous stone, and Carrara marble because it helps resist moisture and protects the surfaces from staining.
The water-based formula means that it protects Carrara marble without altering its natural look. It also does not make marble reflective, which is preferred for marble surfaces with a rustic appearance.
A single quart of this can seal 100 square feet of Carrara marble, but you can definitely make it go a much longer way because less is truly more with this sealant. When applied on interior surfaces, this can last for up to 5 years without reapplication or showing signs of wear.
However, it would be safer to reapply the sealer at least every year or two, especially if the Carrara marble surface is used regularly (such as a countertop or shower marble).
Besides Carrara marble, this sealer can also be used on slate, limestone, grout, masonry, granite, and travertine. It is able to protect so well because of how it penetrates the surface of the material and bonds with it, rather than just sitting on top of it as an extra layer.

Keep in mind that the formula is thinner than most others, so when applying on porous marble, you may need to put in a couple more layers and a bit more time for it to get perfect protection. However, this sealer’s resistance to water and oil damage will be worth that extra effort.

Best Marble Sealer Buying Guide
Besides price and quantity, there are some other features you should be on the lookout for when buying a high-quality marble sealer.
Penetration of the Solution
A sealer for marble is not meant to create a flat layer on the surface with gaps underneath. Most natural surfaces like stone or marble are porous enough that they can be damaged by oils, water, etc.
So, it is essential to get a marble sealer that will layer nicely and settle into the marble’s surface gaps. These gaps may be invisible to the naked eye, but if they are not sealed properly, they will most certainly make the marble prone to damage and wear.
This is why a marble sealer needs to penetrate the surface of the material and harden to create a proper seal.
Ease of Use
Of course, there are marble sealers on the market, which you can simply spray on without the need to get your hands too dirty. However, those will definitely not be as effective as sealers that need to be applied on.
The best marble sealant would be one that you can apply yourself using just a foam brush or a soft rag. You only need to apply one thin layer of this at a time and make sure no bubbles or puddles are forming.
It’s a relatively easy task for the results you can get, which is, the marble will stay undamaged for up to a year.
One thing you absolutely need when applying marble sealant is patience. While sealers typically dry within a few hours of application and can be walked on, it takes them at least 48 hours to fully cure and be ready for use.
Letting any marble sealer fully cure is essential to ensure the durability of the sealer; otherwise, there is no point in applying it in the first place if it needs to be in use again soon after.
You might have just your kitchen countertops to seal, or you might have the flooring of several rooms to seal. Either way, you will need to decide on how much sealant you should buy.
This depends on the area you will need to cover and also on the strength of the coating ability of the sealant. For instance, even the best sealer for marble countertops will need to be applied twice in order to be really effective because countertops are used daily and endure a lot of moisture and friction.
To cover larger areas like the floors of rooms, you will need multiple quarts of a sealer to apply at least two layers of it.
There is no point in applying a sealer to your tiles if it will wear out in months or a year. This is why it’s essential for you to check the retailer’s or manufacturer’s warranty before buying a sealer.
While many sealants can be easy to apply, that does not mean that they should have to be layered on frequently to have the proper impact. And if you get a marble sealer with an extended warranty period and it wears out before that, at least you know that you are covered for a refund or replacement.
Marble Sealer Types
Which type of sealer you will need can differ based on what the marble area is used for and also the type of the marble itself.
Marble Tile Sealer
From floors to bathroom walls to exterior decor, marble tiles are used for a wide number of purposes. Depending on the location and type of marble tile, a sealer should be chosen that can help it resist wear and tear due to water, oil, weights, scratches, etc.
Marble Floor Sealer
Marble, which acts as flooring, is perhaps what needs the highest level of protection. Not only does it endure dust and dirt, but it is also cleaned using some sort of soap and water at least a few times a week. This is why a sealant for marble floors is typically the most durable and protective kind.
Marble Countertop Sealer
Because of how often a countertop (especially one in the kitchen) is used and how much it is exposed to moisture, friction, and oils, marble countertops require a strong sealer that will last a long time while also being food safe.
Marble Table Sealer
Just like flooring and kitchen countertops, the best marble sealers for tables also need to be super resistant to friction, weight, heat, and moisture, which is why a stronger grade of marble sealer is required in order to protect them.
Natural Marble Sealer
Natural marble tends to be full of pores and cracks, making it more prone to water damage, staining, and dissolution. This is where a sealer made specifically for natural marble can help. It will penetrate the surface and settle into the cracks to protect the marble.
Permanent Marble Sealer
Permanent sealers for marble form a molecular level bond with the surface, which is not removable, hence permanently sealing the marble from damage by the external environment.
Marble Penetrating Sealer
Unlike sealers which create a layer on top of marble, penetrating marble sealers are great for porous surfaces because they can seep into the crack and help make the marble resistant to water, oils, scratches, etc.
Frequently Asked Questions (FAQs)
#1. What is the best marble sealer?
Answer: The best sealer for marble would depend on what type of marble you have, as it is a naturally appearing material and different kinds of marble have different levels of tolerance to damage.
Some types of marble are incredibly fragile and will need thicker coatings of sealant. But a good rule of thumb is to choose one that is water-based and has no acids, as they can easily corrode the marble.
Our recommended is Tuff Duck Granite, Grout, and Marble Sealer.
#2. What do you use to seal marble?
Answer: As with many other home improvement projects, the process of sealing marble is pretty straightforward.
You need to first get the best sealant for marble that you can find (this will depend on what type of marble you have and where in your house it is fixed), and then find a foam brush or use a soft rag. Foam brushes help to apply thin and even layers of the marble sealer.
#3. Does polished marble need to be sealed?
Answer: Polished marble is not porous or absorbent. This also means that it is less prone to damage by moisture or regular use. Usually, polished marble is not sealed because of these qualities.
As it does not absorb water, it will also not absorb the sealer either, so there really is no need to use a marble sealer on polished marble surfaces.
#4. How often should you seal marble?
Answer: While you can get away with sealing your marble every couple of years or so, it is always best to seal marble annually in order to really stretch its longevity. Some natural marble types will definitely require yearly sealing in order not to wear down.
When marble is not sealed for a long time, it becomes more prone to moisture and usage damage. Replacing marble is much costlier than sealing it annually.
#5. Can you seal marble yourself?
Answer: There are tons of the best marble sealers on the market designed so that anyone with little experience can use them. For most marble sealers, you only need a foam brush or soft rag to apply them.
Make sure your marble surface is clean and dry, then wipe on the sealer in thin and even layers, waiting for each coat to dry for at least 48 hours.
#6. What happens if you don’t seal marble?
Answer: Unsealed marble is prone to damage from water, oils, and general usage. Most areas made of marble are ones that are always in use, such as floors and kitchen countertops.
This means that these areas are always being exposed to moisture and friction, which can wear down the natural marble over time and ruin its appearance and usability. That is why it is so important to seal marble using a proper sealer.
#7. How often should you seal a marble shower?
Answer: Unless the marble in your shower is polished, it is essential to seal it every six months or so. This is because of how frequently the marble is exposed to water, which wears down the sealer quicker than when it is applied to other marble surfaces.
It may seem excessive, but if you want your marble shower to stay looking good as new, regular sealing is necessary.
#8. How do you keep marble shiny?
Answer: To make your marble surface look shiny, you must first ensure that it is clean. Use a mixture of two parts water and one part hydrogen peroxide and clean the marble with it.
Wipe it dry using the chamois cloth and buff it in tight circular motions to give the marble a shine. You can also wipe on a marble polish using the cloth for extra shine.
#9. How can you tell if marble is sealed?
Answer: In order to test whether your marble has been sealed or not, you can do the water test. Drop a bit of water onto the marble and wipe it up. If the marble has darkened where the water was, it means that it has absorbed the water and is therefore not sealed.
On the other hand, if the marble appears unchanged after wiping, that means it is sealed because it is water-resistant.
#10. What is the best sealer for Carrara marble?
Answer: For Carrara marble, you will need a water-based sealer so that it does not ruin the marble’s natural appearance and one that is very penetrative so that all the pores on the surface of the Carrara marble are sealed.
Carrara marble is incredibly delicate and naturally quite porous. This is why it needs to be sealed more frequently than other materials. Because of how prone to damage this marble is, it needs to be sealed at least once a year.
Our recommended Carrara marble sealer is StoneTech BulletProof Sealer.
As you can tell, sealing marble is a serious and important business. Not only should you seal your marble as regularly as possible, but you should also try to find the best marble sealer, taking into consideration what type of marble you have.
The biggest reason for using marble is that it looks elegant and beautiful. But unsealed marble can be the opposite of that. A good sealer will help keep up your marble’s outstanding appearance, be it interior or exterior.
