Step 1: Clean your marble floor with a solution of water and white vinegar.

This will remove any oil or dirt which may have become lodged in the pores of the stone, making it easier to clean in the future. In addition, this will make it easier for the sealant to penetrate.

Step 2: Apply a marble floor cleaner.

A marble floor cleaner contains limestone powder and helps to remove stains from the stone by penetrating its pores. It also removes any dirt or oil that is lodged in the pores of your marble floor. After you have wiped up most of it with a clean rag or paper towel, use another cloth to buff up the surface so there is no residue left behind. 

This will leave behind a beautiful luster similar to what you see when walking into an expensive spa or hotel bathroom. Knowing how to properly clean marble floors can save you time and money in future repairs as well as help your marble flooring maintain its original beauty.

Step 3: Apply a marble floor sealant.

Now that your marble floors are clean, you can apply a layer of sealant. When applying the sealant to the surface, make sure it is an even coat all over with no spots missed or thick puddles left behind. Make sure to allow at least 4 hours before allowing foot traffic on the surface so that any moisture will be absorbed into the stone as opposed to being trapped underneath. This will avoid damage and leave your floors looking beautiful for years to come.

Step 4: Wipe off any excess sealant.

After allowing the sealant to set for several hours, use a clean cloth or towel to wipe away any excess sealant. This will leave you with a nice thin layer of protection that will not make your floors slippery while still making sure they are protected from staining. 

It takes time to properly care for marble flooring and this is why it's important to do it every few months; but if done correctly, you can be confident that your floors will stay looking beautiful as long as possible.

What kind of marble is best to seal?

There are many different types of marble out there, and they all seal differently. For some, you can use a regular polyurethane aftercare sealant that will last 2–3 years before re-application, while other marbles require special types of sealing.

If your stone is not sealed then look under it to discover its makeup. If it is pure white with veining that looks like snaking rivers running through it, or a solid black slab; then go ahead and choose whichever method you prefer to seal your floors. But if your floor has blue/green veining throughout in addition to the white veins, or it has pink or red tones in it, then you will need to choose a sealant that is made for sealing marble with dark veining.

Sealing your marble floor: Qualities of good sealants

Many sealants on the market will seal your marble, but some are better than others.

These are the sealant qualities to consider:

  • It has to allow enough time for it to absorb into the stone so that it does not leave an oily residue that is noticeable or attracts dirt.
  • It shouldn't change the color of your marble flooring, and/or have any adverse reaction with it at all; otherwise, you risk having discoloration or even cracks form in your floors.
  • In addition, it should also be easy to apply with no mess nor should there be any leftover residue once you've finished applying it.

It's best to use a sealant that is easy to use, and which will last as long as it says it should. There are many different ways you can apply the sealant to your marble floors; with a rag or sponge, spray bottle, or even paintbrush.

What color marble should I choose?

When it comes to marble, there are many different colors out there. Some of the most expensive marbles in the world have a black base with white or yellow veining running throughout.

Most people choose light-colored stone flooring because they think it is easier to keep clean and beautiful looking. While this may be true for you at first, you should consider that if your marble has dark veins then cleaning will be more difficult than on lighter stones, and if it is polished correctly then it can look just as good as its counterparts.

If you want your floors to shine through, especially when lit by natural sunlight; go with a darker color like deep reds or even blues. The darker the color, the more reflective it is, so this will make it more vibrant and beautiful over time while also ensuring that you don't have any trouble shining it up.
