# Quartzite Sealing Toronto | Quartzite Countertops Toronto URL: https://quartzitecountertopstoronto.ca/quartzite-sealing/ Services | 22 Years of Quartzite Fabrication Experience # Quartzite Sealing in Toronto, ON | 18-Month Impregnating Seal, Factory Seal & Colour-Deepening Last updated: October 6, 2026 Quartzite Countertops Toronto [/ →](/) handles quartzite sealing for kitchens, condos and commercial builds in Toronto and the GTA. Quartzite is a metamorphic sandstone at 7 Mohs and acid-resistant, so it will not etch, but its tiny natural pores can still take in oil, coffee and wine without a good seal. We apply Dry-Treat Stain-Proof, a breathable impregnating sealer, in your home, the same sealer every piece from our Park Industries CNC and Flow Mach 500 shop leaves with, whether the slab came from Stone Tile, Ciot, Marsala or elsewhere. We have sealed stone across the GTA for 22 years. A sealing visit runs $350-$950 and protects for about 18 months. We seal Taj Mahal, Cristallo, Mont Blanc, Sea Pearl, Super White and every other quartzite, whoever installed it. Every visit is done by WSIB-covered staff with $5M CGL, NSI-compliant products and our 2-year workmanship warranty on installs, across Toronto, Mississauga, Vaughan, Markham and the rest of the GTA. - 22Y GTA - NSI Accredited - Park Industries CNC - Flow Mach 500 - $5M CGL + WSIB - 2-Yr Warranty Book Free In-Home Consultation & Samples [/contact/ →](/contact/) See Sealing Pricing ($350-$950) [#pricing →](#pricing) ![Technician applying impregnating sealer to a Taj Mahal quartzite counter](https://placehold.co/1920x800/8a6a24/ffffff?text=Technician+applying+impregnating+sealer+with+a+microfibre+pad+to+a+Taj+Mahal+quartzite+kitchen+counter+in+a+Toronto+home) From $350 22 Years GTA Expertise Park Ind.

It is a metamorphic sandstone around 7 on the Mohs scale, it handles heat past 300C and it does not etch from lemon or wine. But it is still natural stone with microscopic pores. Leave olive oil, coffee or red wine sitting on an unsealed counter and some of it can soak in and leave a shadow. A good seal fixes that. We use Dry-Treat Stain-Proof, a fluoropolymer impregnating sealer that soaks into the stone and creates a breathable barrier below the surface. It is hydrophobic and oleophobic, which means water and oil both bead up instead of soaking in, and it does not change how the stone looks or feels. ## Types of Sealing We Offer ### 18-Month Impregnating Seal Our standard reseal visit. Deep clean, Dry-Treat Stain-Proof application, buff and test. Good for about 18 months. ### Factory Seal Every piece fabricated in our Vaughan shop gets sealed before it leaves, then again on install day. ### Topical Seal A surface coating we use only on specific outdoor or commercial surfaces where a sacrificial film makes sense. We do not use topical sealers on indoor kitchen quartzite. ### Colour-Deepening Seal An impregnating sealer with an enhancer that makes stone look richer and darker. Popular on leathered grey, Fantasy Brown and charcoal quartzite. We always test a small area first. ![Water beading on sealed quartzite after a reseal visit](https://placehold.co/800x500/8a6a24/ffffff?text=Close+up+of+round+water+droplets+beading+on+a+freshly+sealed+cream+quartzite+kitchen+counter+near+a+stainless+steel+faucet) ## 5 Signs Your Quartzite Needs Resealing (18-Month Cycle Explained) ### 1\. Water Darkens the Stone The classic test. Drops near the sink should bead. If the stone goes dark under them within ten minutes, the seal is worn. ### 2\. Oil Leaves a Shadow A drip of cooking oil that leaves a faint darker patch after wiping means oil is getting in. ### 3\. The Sink Edge Looks Duller The area around the sink gets the most water and scrubbing, so it wears first. ### 4\. It Has Been 18 Months Even if everything looks fine, 18 months is the right time to test and likely reseal, especially on leathered or honed finishes. ### 5\. You Have Been Using Harsh Cleaners Bleach, vinegar and degreasers do not etch quartzite but they do break down sealer faster. If those have been in use, reseal sooner. > **The 18-month cycle** > > Month 0: factory seal plus on-site seal. Month 12: quick water-drop test near the sink. Month 18: reseal. Repeat. Busy kitchens and leathered finishes may move the reseal to month 12-15. ## How Much Does Quartzite Sealing Cost in Toronto?

See all service prices on quartzite cost Toronto [/quartzite-cost/ →](/quartzite-cost/) . ## Impregnating vs Topical Sealers | | Impregnating (what we use) | Topical | | --- | --- | --- | | Where it sits | Below the surface | On top as a film | | Changes look | No (unless colour-deepening) | Adds shine | | Breathable | Yes | No | | Durability | About 18 months | Scratches and peels | | Best for | Indoor quartzite | Some outdoor uses | ## Sealing Stone We Didn’t Install We reseal any quartzite in the GTA, along with granite and marble. If we test your “quartzite” and find it is actually marble or dolomite, we will tell you, since those need sealing every six months and still etch. Our quartzite vs marble [/quartzite-vs-marble/ →](/quartzite-vs-marble/) page explains the difference. ## Between Visits Clean with a pH-neutral stone cleaner, wipe oil and coffee promptly and run the water-drop test once a year. Our quartzite maintenance and care [/quartzite-maintenance-care/ →](/quartzite-maintenance-care/) page covers daily routines. If you see dull spots, chips or stains that will not lift, book quartzite polishing and restoration [/quartzite-polishing-restoration/ →](/quartzite-polishing-restoration/) and we can often do both on one visit. Straight Talk ## What Actually Stops Toronto Homeowners From Booking Sealing In our opinion, these four questions decide most bookings. Here are the straight answers. ### "Is $350-$950 worth it when I could seal it myself?" In our opinion, sealing yourself is fine and we will show you how. Our visit is worth it when you want it done right in one go: we deep clean, test, apply, cure, buff and water-test before and after. Most clients book us every second cycle and do the in-between themselves. ### "Quartz never needs sealing. Doesn't that make quartz easier?" It does, by about one hour every 18 months. For that hour, quartzite gives you heat resistance past 300C and no UV yellowing. Most homeowners think that is an easy trade. ### "Does sealing stop chips?" No. Sealing protects against stains, not impact. Chips are about edge profile and cutting quality. If you have a chip, we can repair it on the same visit. ### "If quartzite doesn't etch, why seal at all?" Etching and staining are different. Quartzite does not etch, but oil, coffee and wine can soak into unsealed pores. A Dry-Treat Stain-Proof seal keeps them on the surface where you can wipe them.

Precision Workflow ## How Our Sealing Process Works, 5 Steps 1. 1 ### Step 1: Water-Drop Test & Stone Check We start with a water-drop test at the sink, range and island to see where the old seal has worn. We also confirm the stone is quartzite, not marble or dolomite, since that changes the plan. 2. 2 ### Step 2: Deep Clean & Dry We degrease the surface with a pH-neutral stone cleaner, lift any surface stains and let the stone dry fully. Sealer only works on clean, dry stone. 3. 3 ### Step 3: Impregnating Sealer Application Some services wipe on a cheap topical spray that sits on top and peels. We apply Dry-Treat Stain-Proof, a fluoropolymer impregnating sealer that soaks in and forms a breathable sub-surface barrier. 4. 4 ### Step 4: Cure, Buff & Inspection by Marco's Team Marco Delvecchio trained our sealing techs to buff off every trace of excess so there is no haze. We check the surface under raking light before the second coat where needed. 5. 5 ### Step 5: After Test & Reminder We repeat the water-drop test so you can see the stone repel water, then schedule your next 18-month reminder.

Martin Q. from OakvilleWhole-house reseal, $890 Got Questions? ## Sealing FAQ ### How much does quartzite sealing cost in Toronto? A sealing visit runs $350-$950 in CAD and protects for about 18 months. A single vanity or small kitchen sits at the low end. A large kitchen with an island and full-height backsplash, or a whole-house visit with vanities, sits at the high end. Leathered and honed finishes take more sealer. The price includes a deep clean, the impregnating sealer, buffing and before-and-after water-drop tests. ### How often does quartzite need sealing? Every 18 months with an impregnating sealer like Dry-Treat Stain-Proof. Heavy-use areas near the sink and range, and leathered finishes, may need it a little sooner. ### How do I know when it is time to reseal? Do a water-drop test. Put a few drops near the sink, wait ten minutes and wipe. If the stone darkens under the drops, reseal. ### What is the difference between impregnating and topical sealers? An impregnating sealer soaks into the stone and protects below the surface without changing the look. A topical sealer sits on top as a film; it can look shiny at first, then scratch and peel. We use impregnating sealers on quartzite. ### What is a factory seal? The seal applied in our shop after fabrication, before the stone leaves. Every piece we fabricate gets one, plus a second coat on site. ### What is a colour-deepening seal? An impregnating sealer with an enhancer that makes the stone look richer, a bit like the stone when it is wet. Popular on leathered and honed greys and browns. ### How long before I can use the counter after sealing? Light use after about an hour, full use and wet cleaning after 24 hours. ### Do you seal stone you didn't install? Yes. We seal any quartzite, granite or marble in the GTA. If we think the stone is mislabelled, we will tell you. ### Can I seal it myself? Yes. Clean, let it dry, apply a quality impregnating sealer, wait the stated time and buff off every bit of excess. We are happy to show you. ### Is the sealer food safe? Once cured, the impregnating sealers we use are safe for food prep surfaces.
