Buying Guide of Best marble sealer

Nobody likes a dirty home. It gets more disgusting when your beautiful marble floor is covered with a musky layer of dirt. This is where the marble sealer comes to your rescue. To select the best marble sealer in the market, we will need to consider some factors. These factors include:

Penetration of the solution

When selecting a sealant based on its penetrating power, we come across two types. The topical sealer is the penetrating solution that makes a tough barrier between the floor and the greasy dirt layer. This keeps the floor shining as new.

On the other hand, the penetrating sealants penetrate the surface and make a micro bond with its particles. This allows for easy removal of oils and stains. Thus, it leaves the floor glossy. Here, note that topical sealants are used for matte floors while penetrating ones for glossy marble surfaces.

Ease of use

Before selecting a sealant, we prefer that you read the instructions first. It is because not all products have the same way of application. Some are spray-on while some need to be set for 10-20 minutes, depending on the wet floor. But this depends completely on your choice. If you have enough time to clean the surface, you can use anything you want to.

Curing times

To seal the product, sometimes you might need to wait for a long time. The time required for the sealant to work its magic and be ready to use is called curing time. This is necessary when you need to apply multiple coats on the floor. Some products may take less curing time, while some may require 24-72 hours, at least. As we said, you can pick the one you think is right for you.

Product coverage

Depending on the size of the floor and strength of the sealant, the product may come in a bottle of a gallon that covers up to 100 to 4000square feet. We recommend that you should avoid using a spray bottle because it will not have enough product coverage to cover the entire floor.

It is better to use a product that doesn’t need so much fuss. In this case, you can also use a sealant that requires an extra applicator to cover the full surface. This applicator could include a soft pad or cloth.


Warranty is very important before selecting any product. Since the sealant is something that could last a lifetime, select something that has a very appealing warranty. However, before you conclude, make sure that you have enough information about the quality of the product.

You may get some that have 25 years of warranty but are prone to wear and tear over time. It is better to avoid those at all costs. If a sealant gives you 5 years of warranty with the best quality, then pick that one without wasting time.

How to properly seal marble?

If you’ve installed a marble countertop in your house, you need to be careful about its proper maintenance. You’ve to reseal them after a certain time to reinforce their ability to protect against stains.

Sealing: You can understand this by a water test. Pour a few drops of water on various spots of the surface. If they bead in place, you don’t need to apply sealant. But if the water seeps into the surface, then it’s time to apply this process to them.

Cleaning: Spray the cleaner on the counter and dry it with a soft cloth to prevent the stains from interfering in the sealing process.

Applying Sealant: Spray a generous coat of natural-stone sealant so that it completely covers the surface. If the area is large, work in sections.

Buff away the excessive amount with a clean, dry cloth. Apply a buffing motion so that you can see the sealant get absorbed. If it seeps into the marble, apply another coat. Don’t let it completely dry on the surface. If it still stays after 10 minutes, wipe it with a soft cloth.
