What Marble Sealer Is

Marble sealer, also known as a marble impregnator is a waxy substance that’s applied to marble in order to keep from staining or yellowing. It’s an extra barrier of protection for your marble investment. Marble sealer consists of a combination of oils and waxes that is designed to penetrate deep into the pores in the stone. It fills the pores with an oily barrier, which is what helps protect your marble from staining. When water hits this shiny surface, it beads up and repels rather than soaking into the stone itself. Therefore, you don’t have to worry about murky residue or discoloration once it dries.

The oil mixes together with fine particles in order to make a glossy coating on top of your marble. This means that you will get a durable finish once it’s applied properly. However, you need to know how long marble sealer takes to dry in order for it be effective at sealing.

Why Use Marble Sealer

marble-countersThere are multiple reasons why you should consider using a marble sealer:

  1. The sealers will help prevent spills from seeping into the pores of the stone and
  2. They keep dirt particles from leaching out onto your flooring surface. Both these problems can eventually lead to chipping if not addressed
  3. Sealer will improve the look of your marble  floor by filling in stone pores and leveling out discoloration
  4. In the case of unsealed marble, a sealer can be used to smooth over any scratches.

How to Use Marble Sealer


Prepare the marble: you need to dry the surface of the marble with a towel and remove any grease on it. Then, dampen the sponge with water, wipe it on the surface carefully. Rub your fingers or roller to make sure that there is no dust left behind.


Apply plenty of sealant into the sponge then rub it onto your marbles gently until they are shiny and glossed up again. Make sure that you work in even strokes on each section of your stone in order for a smooth finish. The whole process only takes 15 to 30 minutes. You can use cotton swabs or toothpicks to help you apply sealants on every corner of your floors if necessary. After applying the sealer you can let it dry for several hours or overnight. Then, you are ready to put things back in place and enjoy your sparkling marble.

Common Mistakes When Applying Marble Sealer

When people first use marble sealer to protect their countertops, they often have difficulty getting the results they were hoping for. This is usually because of a few common mistakes that are made along the way. Let’s take a look at these:

Improper Prep Work

Marble Sealer will not be able to bond properly if the surface it is being applied on has not been properly prepared beforehand. In order for sealant or polish to stick to any surface, there has to be something that can actually bond with the product. A dirty and dull countertop is simply not going to provide this necessary base for your marble polisher to adhere too effectively.

Improper Applying

white-marble-kitchenAnother mistake that was made often is applying too thin of a coat. The application must be very even so as not to have areas where the polish will not adequately cover and therefore, areas will appear dull in appearance. Thick coats are also another reason for marble sealer failure because when they dry it leaves behind an oily residue which makes the surface much more prone to scratching and scuffing than if you had used just one very thin and even layer.

Using Improper Polishes or Tools

There are some specific types of polishes that should only be used on certain types of countertops. For instance: Oil-based products like soap should never be used on painted concrete.

Frequently Asked Questions

How can you tell if marble is sealed?

The basic rule of thumb is if the finish appears uniform and there are no chips or cracks, it has been sealed. However, in order to be 100% sure, you can do a quick test on the surface to see how likely it is that your marble countertop could get damaged by water. Take a piece of newspaper (make sure no ink from the paper was used on your stone – never use an ink pen on marble!) and pour some water onto the top. If it soaks in quickly without leaving any potential for staining then you know it’s been sealed well!

Does sealing marble change the color?

The common misconception about sealing marble is that it will change its color. While the sealer itself may impart a slight color to the stone, the process should not permanently alter its optical properties.

How often do you need to seal marble?

The frequency with which you need to seal marble will depend on the type of sealant you use, the amount of traffic the surface sees, and how porous the marble is. In general, most people will need to reseal their marble every 1-3 years. However, if you have a high-traffic area or a very porous marble, you may need to reseal it more often. Consult the instructions that came with your sealant for more specific information.

How long does it take for marble sealer to dry?

Drying times can vary depending on the sealer and the type of surface you’re sealing, but most products will require six to twelve hours of dry time. Some products may even require a full day to dry completely.

Do you seal marble before or after grouting?

There is a lot of debate over when to seal marble. Some people say you should always seal it before grouting, others say you should wait until the grout has set. The truth is that it depends on the particular circumstances. In general, though, it is best to seal the marble before grouting in order to avoid staining from the grout.


Getting the best marble sealer can be tricky if you do not know the right things to consider. If you choose to get any of the above products, you are likely to get excellent results. These are the best marble sealers you will find in the market, and they boast of long-lasting effects. Irrespective, when getting your marble sealer, ensure you adequately read the features.
