For kitchen marble surfaces and family homes, a non-toxic sealer with little to no VOCs (Volatile Organic Compounds) will be safe to keep and eat food around the countertop. No VOCs will also make it child friendly. The sealant should be NSF/ANSI 51-2012 compliant.

We would not want harmful substances making their way into your food or harming your family.

A marble sealer should not dull or wear down the natural look of your marble tile. A marble sealer with high-quality ingredients should be the priority when looking for a sealer if you care a lot about your marble presentation. There are premium marble tile sealers that can even enhance your marble color and add a polished finish.

Will not flake or peel

A sealer application should not start flaking or peeling off down the track.  Buying low budget marble sealers may be a culprit, when it comes to flaking and peeling. Avoiding flaking is crucial. Removing marble flaking is another task to attend to and may require professional attention.

Premium sealers

It is easy to find a bargain with cheaper and generic sealants. Investing in a heavy-duty marble tile sealer will typically have a high strength formula, of sealer protection against damage.

Strength of sealer

It is essential to check whether your marble surface has already been applied with a sealer coverage in the past or if it’s still unsealed.

Suppose you’re not sure if an application already exists or not confident about the strength of sealant left on the marble. You can try a water-absorption test to diagnose the power of the marble sealer needed.

You could check which type of sealer has been applied if the surface is already polished. It is worth checking the previous tenants’ or landlords’ chosen kind of sealer when determining whether a lower grade or higher concentrate of sealer is needed. 

Resistant to substances

All types of sealers react differently to various substances. You should think about which substances your surface is more susceptible to damage. A kitchen would be exposed to frozen foods, wine, and citrus fruits. While an outdoors marble surface is faced by daily UV rays. Finding a marble tile sealer that suits your needs should be on your list. 

Non-slip finish

The coverage of a sealer should leave the surface with a non-slip finish. This is important for marble flooring and marble showers. A slip could be fatal. A good marble sealer should absorb into the marble evenly and shouldn’t leave excessive coverage. 

Protection from acid etching

Acid etching is different from a typical stain. Corrosive damage may happen from acidic substances such as wine, coffee, and citrus fruits. Acid etching burns the surface layer and exposes the raw marble, creating a lighter and duller marble surface. A burn may also create permanent damage to your marble.

A polished surface is more susceptible to acid etching damage than a honed surface. So if acid etching is a typical occurrence, it should be something to look for in a marble tile sealer.


A marble surface typically requires a touch-up application of sealant every couple of years or months. So, it might be worthwhile to buy a marble sealant that will last longer. There are premium sealers on the market that can last up to 25 years.

How to perform a water absorption test on marble.

To check if a marble surface already has a marble sealer application. A water absorption test can be performed to diagnose the need for a sealer and its strength. It’s easy to do in a matter of minutes. 

  1. Pour a few drops of water on the marble surface.
  2. Let the water sit on the marble for a few minutes.
  3. Assess the water’s absorption rate and behavior.
  4. If water has beaded up, a sealer application has been applied previously.
  5. If water has been absorbed, the stone will need to be treated with a sealer.
  6. If the marble creates any discoloration or becomes darker, it should be resealed.

Bath products do not damage marble as terribly as other liquids so that sealing wouldn’t be necessary for non-white marble types.

Efflorescence is when salt migrates to a porous material such as marble. The salt builds up and leaves a white coating. Any initial sign of efflorescence should be treated as soon as possible.


Using a special marble cleaner, you should deep clean the surface with a clean cloth, removing stains, liquids, and stains. 


After deep cleaning, you should completely dry the surface.


Depending on the sealer, some sealers may require special techniques, while some are usable out of the box. For best results, follow your chosen sealers’ steps.

It is suggested that you properly ventilate the sealed area for a few days after applying sealant.  Most people won’t react to the fumes.

Polished marble is less porous compared to high porous honed surfaces. Honed marble typically has a matte and low gloss finish compared to a shiny polished surface. Honed marble is generally installed in less visited areas of a household. Polished surfaces may be found in kitchens and flooring. Honed surfaces typically should be sealed to prevent damage.
