Quartz countertops are among the most popular choices for both kitchens and bathrooms due to their durability, modern aesthetics, and low-maintenance appeal. But a question often asked by homeowners and renovators alike is: Do you have to seal quartz countertops? The short answer is no—but there’s a lot more to understand about why sealing isn’t required and how to properly maintain your quartz surfaces.
In this comprehensive guide, we’ll explore everything you need to know about sealing quartz, its composition, advantages, maintenance tips, and how it compares to natural stone alternatives.
What Are Quartz Countertops?
Quartz countertops are a type of engineered stone countertops, made by combining approximately 90–95% ground natural quartz with resins, polymers, and pigments. This manufacturing process results in a non-porous, highly durable surface that mimics the appearance of natural stone without the need for regular sealing.

Why Sealing Quartz Countertops Isn’t Necessary
Non-Porous by Nature
Unlike granite or marble countertops, quartz does not have microscopic pores that absorb moisture or stains. The resin binders fill any natural voids in the quartz, creating a smooth, non-porous surface. This means:
- No need for periodic sealing.
- Better resistance to bacteria, mold, and mildew.
- Easier daily maintenance.

The Exceptions: When You Might Consider Sealing
While factory-produced quartz slabs for countertops are non-porous, some lower-quality or DIY quartz surfaces might have imperfections or exposed edges where sealing could be considered. In rare cases, poorly maintained quartz can also benefit from a protective coating—not a traditional sealant, but more of a temporary surface enhancer.
