If you have newly installed quartzite in your bathroom and kitchen countertops, you may have several questions popping into your head. Is it worth installing quartzite countertops in the kitchen?

Or What are its unique characteristics? People often confuse quartzite with quartz, but it is another natural stone formed by the metamorphism of sandstone at 1300 to 1600 degrees Fahrenheit.

So, does quartzite need to be sealed? To ensure its maintenance, it is necessary to seal quartzite just like other natural stones.

However, what challenges can you face in cleaning and sealing it? We will share all the details in this article.

How to Know Your Quartzite Need to Be Sealed

The sand collected from dunes gathers to form sandstone which is then passed through extreme temperatures to turn into quartzite. The stone has a similar appearance to marble but has better durability and more perfection for interior design. Tiny pores on its surface require it to be properly sealed because liquids can seep to cause discoloration and bacterial growth.

All About Quartzite Countertops

  • Run A Test

You can see signs of the need to seal quartzite when dark areas appear in different places. One way to test it is by adding hot water and leaving it for 15 to 20 minutes. Wipe water after a certain period and see if there are dark spots; apply a sealant.

Some homeowners have complained that sealing quartzite is a challenging task. The issue arises when quartzite is treated as quartz, considering its physical appearance. Still, quartz is nonporous and doesn’t need to be sealed, while quartzite requires proper sealing.

You must look at the sink if you wonder when to reseal quartzite. If the surrounding areas of the sink are turned dark, the old sealant has lost its strength. It would be best to reseal all countertops as soon as you notice a color change.

Is Quartzite Different From Quartz

Is Quartzite Different From Quartz? This question seems like a puzzle to most people who consider quartzite and quartz similar. But in actuality, these two are completely different in their composition, maintenance, appearance, and sturdiness.

  • Quartzite comprises 90-99% of quartz content, making it a 100% natural stone bonded by silica. In contrast, quartz is processed or molded in varying forms to remain 90-94% natural. The other percentage is due to polymers and pigments.
  • Quartz forms under pressure and through several man-made experiments modifying colors and patterns. It can turn from orange to deep pink while passing through different phases. In contrast, quartzite usually has a gray or white color which changes into pink or red after iron oxidation.
  • The surface of quartzite contains numerous microscopic pores, while quartz has a non-porous surface,
  • The strength and scratch-resistant ability of quartzite are higher than quartz, and the surface doesn’t etch due to accidental falls.
  • Quartzite is also comparably more heat-resistant than quartz, and keeping hot pans on counters won’t leave scars.

An unsealed quartzite countertop will get stains and lose its originality over time. To seal it properly, follow these simple steps:

  • Get a good-quality and long-lasting sealant suitable for quartzite. The whole process will require only half to a complete hour.
  • Before applying sealant, make sure the counters are clean and dry.
  • Apply one layer and leave it for many hours to dry completely.
  • Apply a second coat if needed and leave again overnight.

What Is The Best Sealer For Quartzite 

The most recommended sealers for quartzite are obtained from acrylics, polyurethane, or natural wax. These are the most popular sealers due to their magical results and ease of application. Whichever sealer you choose, read the instructions on the back and follow them accordingly.

You can use penetrating seals composed of silicone and liquid-repellent components that are best for filling pores. Test it again to check if the surface is sealed properly. Impregnating nano sealers are ideal for quartzite countertops.

How Often Does Quartzite Need to Be Sealed

Many suggest resealing countertops after one year, but you should seal them whenever necessary. Making a timeline to seal stone only at a specified period is unnecessary. However, the stone usually requires sealing every 1 to 5 years. Factors such as color, quality, porosity, and sealant decide the period. You can estimate the right time for the application by running a water test.

The frequency can vary depending on the usage and condition of countertops.

What Are The Safe Ways to Clean Quartzite Countertops

You do not only need to seal quartzite, but proper cleaning is also essential to make it last forever.

  • Always use a mild or safe cleaner for cleaning to avoid damage to the sealant or stone. Hot water or soap is completely safe and effective for cleaning.
  • Another great way to clean it is by applying the paste of baking soda and water. Let the paste sit over the stained or dirty areas and wipe it with a clean cloth.

Do not use harsh or strong chemicals for cleaning because they can damage the surface to deeper layers. Here are some cleaning agents you should always avoid using on quartzite countertops

  • Citrus liquids
  • Acidic cleaners
  • Vinegar
  • Bleach
  • Lemon
  • Grout, bath, or glass cleaners
  • Hydrogen Peroxide.

Applying these solutions will dull the color and also speed up wearing out.

  • Regularly clean them or after every use to ensure no dirt is left on the counters.
  • Whenever you notice dull colors, polish the surface.
  • Use a soft cloth to remove leftovers or spills gently.
