When shopping for countertops, quartz stands out as a sleek, low-maintenance option. It looks like natural stone but doesn’t need the same level of care. That might leave you wondering—do quartz countertops need to be sealed like granite or marble? If you’re looking for answers before installing or cleaning your quartz surface, you’re in the right place.
This guide breaks it all down in simple terms. You’ll learn if sealing quartz is necessary, what happens if you do seal it, and how to care for it the right way.
Do You Have to Seal Quartz?
No, quartz countertops don’t require sealing. While natural stone countertops like granite and marble are porous and need sealant to block out stains, quartz is different.
Quartz is non-porous due to its manufacturing process. It’s made with a mix of natural quartz, resins, and pigments. That mix creates a naturally resistant surface that repels spills and bacteria. Unlike granite or marble, quartz doesn’t absorb liquids, so sealing it isn’t just unnecessary—it can actually cause problems.
What Makes Quartz Different From Natural Stone?
Quartz countertops aren’t cut from a single slab of stone. Instead, they’re engineered using around 90–95% crushed natural quartz, a small amount of resin to bind it, and added color and design elements. That combo gives quartz the look of natural stone countertops without the porous nature that needs extra sealing or care.
| Material | Porous? | Needs Sealing? | Maintenance Level |
| Granite and Marble | Yes | Yes – typically every 1-2 years | Moderate to High |
| Quartz | No | No – has built-in protection | Low |
When Might Sealing Quartz Be Considered?
In rare situations, sealing quartz may come up. But that usually means there’s a problem. Here’s when you might think about it:
- You’re dealing with older quartz countertops that have surface damage
- The quartz is low-quality or not sealed properly during manufacturing
- There’s heavy daily use that wears down the finish over time
Still, even in these cases, using sealant on a quartz surface isn’t the go-to solution. Most of the time, a good cleaning routine will do the trick.
Why Shouldn’t You Seal Quartz?
Quartz comes with what you could call a permanent seal built in. There’s no need to add more. Trying to seal quartz can actually backfire. Since the surface doesn’t absorb sealant, it just sits on top, leaving behind a sticky or hazy residue.
You might also see streaks or blotches if the sealant dries unevenly. On top of that, some manufacturers won’t cover damage caused by sealing products, so using one could void your warranty.
How to Take Care of Quartz Countertops
| Care Task | What to Do |
| Daily Cleaning | – Use a soft cloth or sponge with warm water and mild dish soap
– Wipe up messes quickly to avoid buildup – Avoid letting water sit too long, especially near seams |
| What to Avoid | – Harsh chemicals like bleach, oven cleaner, or ammonia
– Abrasive scrubbers or steel wool – High heat—always use trivets for hot pots and pans |
| Handling Spills | – Clean spills right away, even though quartz is non-porous
– Quick cleanup helps keep the surface smooth and the finish strong |
Can You Use the Same Care Routine for All Countertop Materials?
Do quartz countertops need the same care as other materials? Not exactly. Each type of surface has different needs:
- Marble countertops need regular sealing and can stain easily.
- Granite and marble are more sensitive to acidic spills like lemon juice or vinegar.
- Quartz surfaces are stronger against stains but can still get damaged by extreme heat or the wrong cleaners.
So while you might clean your other countertops one way, quartz has its own simple routine—no sealing required.
Sealing Quartz the Right Way
Sealing quartz isn’t part of normal upkeep. Thanks to the way it’s made, quartz doesn’t absorb spills the way natural stone does. Unless the surface is damaged or very old, applying a sealant can do more harm than good. Instead, focus on safe cleaning products and good habits to keep your quartz countertops looking like new.
