Quartz countertops are an increasingly popular choice for modern kitchens, thanks to their durability, aesthetics, and low maintenance. However, there is some debate around whether new quartz countertops need to be sealed. Here is a detailed look at the pros and cons of sealing a new quartz countertop to help you decide if it is the right choice for your kitchen.
What is a Quartz Countertop?
Quartz countertops, also known as engineered stone countertops, are made from crushed quartz combined with resins and pigments. The quartz makes up over 90% of the material, making it an extremely hardy and resilient surface.
Some key features of quartz countertops:
- Extremely durable – resistant to scratches, stains, heat, and cracks
- Available in a wide range of colors and patterns
- Non-porous so does not need to be sealed for sanitation
- Low maintenance compared to other natural stone countertops
- Does not need to be sealed initially like granite or marble
Should You Seal a New Quartz Countertop?
When a quartz countertop is newly installed, the main question homeowners have is whether it needs to be sealed right away. Here are the key considerations:
Pros of Sealing:
- Provides an extra layer of protection from stains and etching.
- May make the countertop slightly easier to clean and keep free of residue.
- Could potentially extend the lifespan and maintain the look of the countertop.
Cons of Sealing:
- Quartz already comes pre-sealed from the factory, so extra sealing is often unnecessary.
- Sealants cannot penetrate quartz like natural stone and mostly provide surface-level protection.
- Re-application would be required over time.
- Risk of sealant interacting poorly with the chemicals used in the quartz manufacturing.
Expert Opinions on Sealing Quartz
Most experts agree that sealing new quartz countertops is usually unnecessary:
- Quartz manufacturers indicate that their products are pre-sealed and do not require additional treatment.
- Installers recommend avoiding sealants as they may damage the engineered quartz surface.
- Consumer reports found sealants provided minimal benefits and were not worth the cost.
However, some homeowners may opt to seal their quartz counters for extra protection and peace of mind. Always test sealants first and consult your countertop provider.
When to Consider Sealing a Quartz Countertop
While sealing new quartz may not be helpful, there are some cases when a sealant could be applied:
- If you notice etching, staining or damage appearing on the countertop surface over time. A sealant may help protect vulnerable areas.
- For quartz in high traffic kitchens that require enhanced stain resistance. Re-apply sealant every 1-2 years.
- On lightly colored quartz that shows residue easily, a sealant can make cleaning easier.
- For homeowners that want an added layer of protection for peace of mind.
How to Seal a Quartz Countertop

- Consult your countertop provider to see if they recommend a compatible sealant.
- Select a non-toxic, food-safe sealant specifically designed for quartz.
- Clean the countertop thoroughly before application.
- Apply the sealant evenly according to product directions.
- Allow proper drying time before using the countertop.
- Re-apply sealant every 1-2 years based on usage.
Maintaining Quartz Countertops
To keep your quartz counters looking like new with or without a sealant:
- Use trivets and coasters under hot pots and pans to prevent burns.
- Clean up spills quickly to prevent stains.
- Use a gentle cleaner and soft cloth for routine cleaning.
