Introduction: Quartz and Sealing – Clearing Up the Confusion
If you’re eyeing quartz for your next countertop, you’ve probably heard it’s a low-maintenance dream—no scrubbing, no fuss, just wipe and go. But then comes the question, “Does quartz need to be sealed?” With natural stones like granite requiring yearly sealing to stay stain-free, it’s natural to wonder if quartz has the same catch. After all, who wants to add another chore to the list when picking a countertop that’s supposed to make life easier?
At The Countertop Store, located at 14844 Ingram Rd, North Little Rock, AR 72117, we’ve helped countless homeowners navigate quartz’s perks and pitfalls. In this 2025 guide, we’re diving deep into whether quartz needs sealing—exploring its makeup, maintenance, and how it stacks up against other materials. Let’s cut through the noise and get you the answers you need to decide if quartz is your countertop match!
Quartz 101: What Makes It Different?
Before we tackle sealing, let’s understand what quartz is and why it’s special.
Quartz Defined
Quartz countertops—often called engineered stone—are made from 90-94% crushed natural quartz (one of Earth’s hardest minerals) mixed with 6-10% resins, pigments, and binders. Brands like Silestone, Caesarstone, and Cambria craft these slabs into stunning, durable surfaces that mimic granite or marble.
Why Sealing Comes Up
Natural stones like granite or marble are porous—tiny holes let liquids seep in, so sealing fills those gaps to block stains and water damage. Quartz’s engineering changes the game—but does it eliminate sealing entirely? Your intent is clear: you want a countertop that skips the hassle. Let’s find out if quartz delivers.
The Big Answer: Does Quartz Need to Be Sealed?
Spoiler alert: No, quartz does not need to be sealed. Here’s why:
Non-Porous Perfection
- The resin in quartz fills every microscopic gap during manufacturing—unlike granite’s natural pores, quartz is 100% non-porous. Liquids like wine, oil, or coffee can’t penetrate, so sealing isn’t needed to protect it.
Manufacturer’s Promise
- Top brands back this up—Silestone offers a 25-year warranty, Caesarstone a lifetime one, and Cambria a limited lifetime guarantee. None mention sealing because it’s built to resist stains and water straight from the factory.
Real-World Proof
- Spill red wine and leave it overnight? On quartz, it wipes off with soap and water—no staining, no panic. Granite without sealing? That’s a permanent mark unless you’ve got a pro fix ($200-$500).
Why It’s a Win
- No sealing means no yearly chore—no $10-$20 DIY sealant or $50-$100 pro job. Quartz saves time and cash—perfect if low maintenance is your goal.
Why Quartz Skips Sealing: The Science Behind It
Let’s dig into what makes quartz a no-seal star—and where it might still trip up.
Resin’s Role
- That 6-10% resin isn’t just glue—it’s a sealant baked into the slab. It binds quartz particles, creating a waterproof, stain-proof shield. Granite’s natural pores need external sealant; quartz’s are pre-filled.
Durability Bonus
- Hardness: Mohs 7—quartz crystals resist scratches, keeping the surface intact.
- Stain Resistance: Non-porous means no absorption—spills sit on top, not inside.
- Bacteria Resistance: No pores, no germs—ideal for kitchens.
The Catch
- Resin isn’t perfect—heat above 300°F can damage it (more on that later). But for sealing? It’s a non-issue—quartz’s structure handles liquids without help.
Testing It Out
- Manufacturers run “porosity tests”—quartz scores zero absorption. Granite? 0.2-1% without sealing—small but enough to stain. Quartz laughs at spills.
Quartz vs. Other Countertops: Sealing Showdown
Does quartz’s no-seal status make it king? Let’s compare:
Granite
- Sealing: Yes—yearly ($50-$100).
- Why: Porous (0.2-1% absorption)—stains set without sealant.
- Effort: 30 minutes DIY or $100 pro—miss it, and lifespan drops (20-30 years vs. 50-100).
- Vs. Quartz: Quartz wins—zero upkeep vs. granite’s chore.
Marble
- Sealing: Yes—every 6-12 months ($50-$100).
- Why: Super porous—stains and etches (acids like lemon juice)—needs constant care.
- Effort: More frequent than granite—lifespan shrinks (20-50 years) if neglected.
- Vs. Quartz: Quartz dominates—no sealing, no etching stress.
Butcher Block
- Sealing: Yes—oiling every 6-12 months ($10-$20).
- Why: Wood soaks water—warps or rots without oil.
- Effort: 15-30 minutes monthly—plus sanding for scratches.
- Vs. Quartz: Quartz is effortless—butcher block’s a labor of love.
Stainless Steel
- Sealing: No—non-porous metal.
- Why: Naturally waterproof—stains don’t stick.
- Effort: Wipe with polish ($5-$10)—scratches show but don’t penetrate.
- Vs. Quartz: Tie—both skip sealing, quartz prettier for most.
Verdict
- Quartz and stainless steel lead—no sealing, minimal fuss. Granite, marble, and butcher block lag—extra steps cut into “easy” vibes.

Quartz Maintenance: What You Do (and Don’t) Need
No sealing doesn’t mean zero care—here’s quartz’s reality:
Daily Cleaning
- What: Damp cloth, mild soap—30 seconds tops.
- Why: Non-porous—spills don’t sink in, just wipe off.
- Cost: $1-$2/month—soap’s all you need.
Tough Spots
- What: Non-abrasive sponge—coffee rings or grease vanish.
- Why: Stain resistance—nothing sets unless you ignore it for weeks.
- Cost: $2-$5—sponge lasts months.
No-No’s
- Heat: Trivets ($5-$20)—hot pans above 300°F burn resin ($200-$500 fix).
- Harsh Chemicals: Skip bleach or oven cleaner—dulls finish over time.
- Heavy Impact: Dropped pots chip edges—$200-$500 repair.
Long-Term Care
- What: Nothing—30-50 years without sealing or polishing.
- Why: Built to last—resin keeps it sealed forever.
Real-World Ease
- Spill ketchup and forget it for a day? Quartz doesn’t care—granite’s crying for sealant.
