Sealing Quartz Countertops: The Benefits

Are you ready to make the big decision of choosing a custom countertop for your home? When selecting new countertops for your home, quartz has become increasingly popular this year, especially in American homes. It is a natural material known for its strength and durability. It is a versatile material and comes in a range of shades from white to very dark grey, almost entirely black. Small hexagonal prisms characterize quartz in the stone, which can also come in a variety of colors. These impurities help to bring depth and uniqueness to any counter. 

With one of the most attractive appearances and known for being long-lasting, it’s no wonder that most individuals are choosing to have quartz countertops installed in their homes. Some of the benefits included with quartz countertops are:

  • A much bigger range of many different colors.
  • Same durability as concrete or granite.
  • The finish has a unique depth.

When making the decision to seal your countertops, it’s important to look at the many benefits from the process. Regardless of other comments that say it might not be needed, quartz can be sealed by using the correct and proper sealers. Some of the benefits of sealing countertops include:

  • Avoid surface scratches and other visual imperfections.
  • Stain prevention.
  • Healthier environment.
  • Less time spent cleaning.
  • Maintained color.

When looking online, there are many websites that state that quartz is stain-resistant. However, because there are so many different manufacturing processes, the quality of your countertop surface can vary. Therefore there is an increased likelihood of liquid/debris getting into the pores of the material. So, depending on where you purchase your countertop, there is a chance that it will be prone to staining. 

To reduce the porosity of a countertop, different styles of manufacturing can be used. It’s essential to research what sort of manufacturing process was used to create your countertop, so you can decide to sell it if needed. 

There are plenty of harsh chemicals that can damage your countertop over time, especially if it isn’t sealed. Using an appropriate quartz sealer can help prevent damage from:

  • Abrasive solutions
  • Strong alkaline
  • Acid Cleaners
  • Free Radicals 
  • Oxidizers 

Suggested Quartz Sealers

If you do decide to seal, it’s important to do your research and find out the best product for you. Are you simply looking for product that is easy and convenient? Something that you only have to do once or month or every few weeks? Or are you looking for a daily cleaner that can also maintain protection against the elements? Below I will recommend some of the most well-known sealers on the web and how they can help protect quartz countertops. 

Supreme Surface Granite & Quartz, Cleaner, Polish and Sealer with ioSeal Protectants

With a 4 star rating on, the Supreme Surface Sealer works by forming a protective barrier over the surface, making it more resistant to stains and fingerprints. It improves the look of the quartz over time and makes it easier to remove stubborn stains in the future. The applicator is very easy to use, as it comes in a spray bottle and lasts for a long time on the surface. However, this product may be expensive compared to others on the market.



Lustro Italiano Ultra Premium Stone Sealer, 8-1/2-Ounce

This particular brand is water-based and protects against stains, spills, and dirt. It is safe to use on surfaces that may come into contact with food, and will not create a film over your natural stone countertop. 

This a premium product that offers up to 5 years of protection with just one application.

Granite Gold: Sealer Spray

This particular product is not only suitable for granite but is recommended for quartz as well. Listed on as the best product to use for quartz, it explains how it is non-toxic, non-acidic and doesn’t use any ammonia or phosphates. This particular brand comes in an easy to use spray bottle that is said to protect against water, oil, coffee, and wine. This is a great inexpensive option. However, it doesn’t last very long on the surface and needs to be reapplied often. 


Weiman: Quartz Countertop Cleaner and Polish

With one of the highest ratings on (4.5 stars), Weiman Countertop Cleaner and Polish is said to protect the resins in the quartz, promising to reduce the stones from fading or darkening, due to sunlight exposure. However, this product again does not seal for very long and must be applied regularly to ensure staining does not occur.

Dry-Treat: Premium Impregnator for Countertops

Dry-Treat is a company that has been creating sealants for over two decades. Their Premium Impregnator sealant is approved for use on quartz countertops and is designed to provide the smoothest finish. What separates this brand from other sealants is the fact that it is comprised of molecules that are significantly smaller than ones found in other sealants. These molecules can bond together more tightly, creating a stronger, more impermeable seal. It also means that they can comfortably rest in even the smallest crevasses in your quartz, providing protection from stains and more severe types of damage. 

Quick Benefits Recap of Sealing: 

  • Easier to clean and maintain during the day to day life.
  • Prevents scratches and grazes on the surface.
  • Prevents stains and fingerprints.
  • Less worry when cooking in the kitchen.
  • Most brands are non-toxic and safe to use in kitchen areas where food is present.
