Marble Sealer Facts You Should Know Before You Shop

Over time, some liquids cause staining and damage to the marble. Sealers work by stopping these liquids from soaking into the marble.

  • Marble Sealers Are Impregnator Sealers. Marble sealers are a mixture of solvent (usually water-based) and resin. The solvent seeps into the marble pores, and the resin clogs the pores, sealing them after the solvent evaporates.
  • Marble Sealers Need Time. When you pour sealer on unsealed marble, it is absorbed very quickly. It will take a few cycles of applying the sealer, waiting for the recommended drying time, and then applying more sealer before you achieve the maximum sealing effect.
  • Marble Sealers Help Prevent Stains. Since the sealer has blocked the marble’s pores, there is little room for liquids to get in and stain it.
  • Marble Sealers Will Not Stop Etching. Sealed marble is not impervious to either scratching or etching. Etching marks on marble are caused by acidic substances such as orange juice and lime juice.

What Should I Be Looking for in a Marble Sealer?

The best marble sealer brands go beyond simply sealing the pores of your marble surfaces. Here’s how to tell if you have a sure winner!

  • Low to No VOCs. Volatile organic compounds (VOCs) are released from many different sources and can lower indoor air quality. Seek out marble sealers that have low to no VOCs and are more environmentally friendly.
  • Certified Safe. Marble countertops grace many food preparation areas. For this reason, your choice of marble sealer must meet the requirements of regulatory bodies and be certified safe for use.
  • A Solid Warranty. Top-quality marble sealers will normally offer a warranty of 10 years or more. The manufacturer may, however, require that you use an authorized installer. Otherwise, the warranty may be shorter or void.
  • Resistant. A good marble sealer should not stain your marble. It should, however, be adhesion-tested, acid resistant, and heat-resistant.

What is a Marble Sealer?

A marble sealer is a product used to protect marble surfaces from staining and other damage. It is typically applied to the surface in a thin layer and then left to dry.

Once dry, the sealer forms a barrier on the surface of the marble that helps to resist dirt, spills, and other potential sources of damage. Sealers can be applied to indoor and outdoor marble surfaces and are typically available in water-based or solvent-based formulas.

Why Use Marble Sealer?

Marble is a natural stone material that is highly prized for its beauty and elegance. Marble floors and countertops can add a luxurious look to any home. However, marble is also very porous, which means it can easily stain.

A good sealer will help to protect your marble surfaces from stains and other damage.

There are many different types of marble sealers on the market, so choosing the right one is important. Some sealers are designed for indoor use, while others are better suited for outdoor use. You will also need to decide whether you want a water-based or solvent-based sealer.

Water-Based Sealers

Water-based sealers are simpler to apply and will not yellow or discolor marble as some solvent-based sealers might. Water-based sealers, on the other hand, may not endure as long as solvent-based sealers.

Solvent-Based Sealers

Solvent-based sealers penetrate the marble more deeply, which means they can provide longer-lasting protection. However, they can be more difficult to apply and may yellow or darken the marble.

When choosing a sealer, always read the manufacturer’s instructions carefully. This will help you choose the right product for your needs and avoid damaging your marble surfaces.

How To Apply Marble Sealer?

Marble sealer can be applied in several ways, depending on the type of surface you are working with. For example, if you’re sealing a countertop made from cultured marble, you’ll want to use a different method than if you’re sealing natural marble tile floors.

In general, however, the process is similar regardless of the type of surface you’re working with.

To seal marble countertops, you’ll need to start by cleaning the surface with mild detergent. Once the surface is clean, apply the sealer with a soft cloth or sponge. Work in small sections, and wipe away any excess sealer that might pool on the surface.

To seal marble tile floors, you’ll need to sweep or vacuum the floor first to remove any dirt or debris. Once the floor is clean, you can use a mop or sponge to apply the sealer. Work in small sections, and wipe away any excess sealer that might pool on the surface.

Let the sealer dry for the amount of time recommended by the manufacturer. Once it’s dry, you can then apply a second coat if necessary. Again, work in small sections and wipe away any excess sealer.

Once the sealer is completely dry, you can put furniture back in place and enjoy your newly sealed surfaces!

10 Mistakes When Applying Marble Sealer

When it comes to marble, the process of sealing it is often seen as a necessary evil. Many people don’t enjoy doing it, but they understand that it’s important to keep their marble looking its best.

However, even if you don’t enjoy the process, it’s still important to do it correctly. Otherwise, you could make serious mistakes that will damage your marble.

Here are 10 of the most common mistakes people make when sealing their marble:

1. Not Cleaning First

This is probably the number one mistake people make when sealing their marble. You can’t just slap a sealer on top of dirty marble and expect it to do its job properly. The dirt and grime will interfere with the sealer’s ability to bond with the marble, which means it won’t be as effective.

Before you can even think about sealing your marble, you need to give it a good cleaning. This will ensure that the sealer has a clean surface to bond with.

2. Using the Wrong Sealer

Different types of sealers are available on the market, and not all are created equal. Some are better suited for certain types of marble than others. If you use the wrong type of sealer, it may not work as well, or it could even damage your marble.

Do your research to ensure you’re using the right type of sealer for your particular marble.

3. Applying Too Much Sealer

When it comes to sealers, more is not necessarily better. If you apply too much sealer, it can cause problems. The excess sealer can pool on the surface of your marble and dry there, leaving a sticky residue.

It’s important to follow the instructions on your particular sealer so that you don’t apply too much.

4. Not Waiting Long Enough to Apply the Sealer

After you’ve cleaned your marble, you need to give it time to dry completely before you apply the sealer. If you don’t, the sealer may not adhere properly to the marble and could start peeling off.

5. Applying the Sealer in Direct Sunlight

The sun can cause problems when you’re trying to apply a sealer. The heat from the sun can cause the sealer to dry too quickly, making it difficult to apply evenly.

Apply the sealer in a cool, shady area, so you don’t have to worry about the sun interfering.

6. Not Letting the Sealer Dry Completely

After you’ve applied the sealer, you need to let it dry completely before you do anything else. If you don’t, it could affect the way the sealer works, and it could also cause problems with your marble.

7. Applying a Top Coat Too Soon

If you apply a top coat to your sealed marble, you must wait until the sealer has completely dried. If you don’t, the top coat could cause the sealer to come off your marble.

8. Not Polishing After Sealing

After your marble is sealed, you should always polish it to ensure the surface is smooth and even. If you don’t, the sealer could start peeling off in spots or make your marble look dull.

9. Not Resealing Regularly

Sealers don’t last forever, so you need to reapply them regularly. How often you need to reseal will depend on the type of sealer you’re using and how much traffic your marble gets.

10. Using the Wrong Cleaner

When cleaning your sealed marble, you need to be careful about the cleaner you use. Some cleaners can damage the sealer and cause it to come off.

Always read the labels on your cleaners to make sure they’re safe to use on sealed surfaces.

If you avoid these mistakes, you’ll be able to seal your marble and keep it looking its best properly.

Frequently Asked Questions

Should Marble be Sealed?

If you want to preserve the quality of your marble, the Natural Stone Institute recommends sealing marble with a quality sealer. Protect your investment by applying a marble sealer.

What Happens if You Don’t Seal Marble?

If you don’t seal your marble, you may encounter serious issues such as shifting tiles, cracks, and marble displacement. You will also have a higher probability of growing mold or mildew behind the tiles.

How Long Does Marble Sealer Last?

It depends on the stone and the finish. Some sealants require reapplying every year. Other sealants need to reapply every 3 to 5 years.

Does Marble Need Grout?

The purpose of grouting floors is to prevent any movement or separation between the stones. The durability and beauty of a well-laid floor depend on how expertly this has been done.

If you’re laying a marble floor, you don’t need grout if the layout is perfectly square. However, this isn’t recommended because you won’t have room to fix any problems in the grout joints.

Do You Seal Marble Before Or After Grouting?

This is a common question that we get asked all the time. The answer is that it depends on the type of marble that you have. If you have a softer type of marble, then it is best to seal it before grouting.

This will help to protect the marble from any damage that may occur during the grouting process. If you have a harder type of marble, then you can seal it after grouting. This will help to keep the marble looking its best for a longer period.

Are Marbles Soft Or Hard?

Marbles are often considered hard, but they can be quite soft. This is because marbles are made from various materials, including glass, stone, and even plastic.

The hardness of marble depends on its material composition and how it has been crafted. For instance, glass marbles are typically harder than those made from clay or stone.

However, some marbles made from softer materials can be just as hard as glass if polished to a high shine. Ultimately, the hardness of marble is relative and depends on its components.

How Long Does It Take For Marble Sealer To Dry?

It depends on the sealer, but most marble sealers will dry within 6-12 hours. However, it is always best to check the manufacturer’s instructions to be sure. Some sealers may require a longer drying time.

If unsure, it is always best to err on caution and give the sealer more time to dry.

How Often Do You Need To Seal Marble?

Marble is a natural stone that is used in a variety of applications, from countertops to flooring. While it is a durable material, it is also porous and can be stained if not properly sealed. Sealing marble will protect it from staining and make it easier to clean.

How often you need to seal your marble depends on a few factors, such as the type of marble, location, and how often it is used. For example, honed marble, which has a matte finish, will need to be sealed more often than polished marble.

A marble located in high-traffic areas or areas exposed to water or other liquids will also need to be sealed more frequently.

Generally, marble should be sealed at least once a year. However, if you have a honed marble countertop in your kitchen that sees a lot of use, you may need to seal it every few months. If you are unsure how often to seal your marble, consult a professional.

Does Marble Scratch Easily?

Yes, marble can scratch quite easily. However, there are ways to prevent or minimize scratching. For example, coasters and placemats can help protect your marble surfaces from scratches.

In addition, avoiding using harsh cleaning products or abrasive scrubbing pads can also help keep your marble looking new. If you find yourself with a scratch on your marble, there are a few ways to try removing it.

First, try rubbing the scratch with a soft cloth and warm water. If that doesn’t work, try the baking soda and a water paste. Another option is to use a pencil eraser to try and buff out the scratch.

If all else fails, you can always contact a professional marble restoration company to have the scratch removed. Taking a few simple precautions can help keep your marble looking new for years to come.


Marble is an amazing material that can be found in many different colors and patterns. It is porous, so liquids can seep into it if not sealed properly.
