What is a Quartz Countertop?
Quartz countertops, also known as engineered stone, are made from ground natural quartz crystals blended with polymer resins and pigments. The quartz provides strength and durability, while the resins bind the material together.
Some key features of quartz counters:
- Extremely hard and scratch-resistant surface
- Non-porous – resists staining from spills
- Available in a wide range of colors and patterns
- Low maintenance compared to natural stone
- Resists heat and scorching better than solid surface counters
Do You Need to Seal a Quartz Countertop?
You do not need to seal a quartz countertop when it is installed or on a regular basis. Quartz is non-porous, so liquids do not penetrate the surface.
However, sealing can provide some benefits:
- Adds a protective barrier against stains from spills
- Helps fill in micro-scratches and polish the surface
- Keeps the counter looking clean and vibrant
- Makes cleaning and maintenance easier
So sealing is optional but can help enhance the look and lifespan of your quartz counters.
How Often Should You Seal a Quartz Countertop?
For new quartz counters, you can apply an initial seal during installation or shortly after. This gives an added layer of protection right away.
After the initial seal, reapply sealant every 1-2 years depending on use and condition. Counters used heavily in a kitchen may need more frequent sealing than bath or laundry room counters.
Signs it’s time to reseal:
- Counter appears stained or dull
- Liquids take longer to bead up on the surface
- Food stains are harder to remove
Using sealant regularly will keep the countertop looking its best.
What is the Best Sealant for a Quartz Countertop?
Look for a stone/quartz sealant made specifically for engineered stone. General granite or stone sealers may not bond as effectively.
Some top options include:
- Miracle Sealants 511 Impregnator – Provides stain protection, water-repellency and resistance to etching.
- Tenax Hydrex – Water-based impregnating sealer, excellent reviews from users.
- GranQuartz Seal & Shine – Designed for both natural and engineered stone.
Avoid flimsy spray sealers. Opt for a penetrating sealer that soak into the pores and provide long-lasting protection.
How to Seal a Quartz Countertop
Sealing quartz counters is a simple process:
1. Clean the Counter
Use a stone cleaner or mild dish soap and water to clean the counter. Rinse thoroughly and let dry completely. Remove any residues that could block sealer absorption.
2. Apply the Sealant
Pour a small amount directly onto the counter and spread evenly with a lint-free cloth or foam applicator. Cover the entire surface.
3. Allow Sealant to Soak In
Let it sit for 5-15 minutes so it can fully absorb. Don’t let it pool or dry on the surface. Wipe away any excess.
4. Buff Off Residue
Use a fresh dry cloth to remove any remaining sealer until the counter has an even sheen.
5. Allow to Cure
Leave the quartz untouched for at least 2-3 hours. Some sealers take 24 hours to fully cure. Avoid water contact during this time.
Reapply sealant once a year or as needed to maintain protection. Proper sealing keeps quartz counters looking like new!
FAQs About Sealing Quartz Countertops
Should quartz counters be sealed before using?
Yes, it’s ideal to seal them right after installation for immediate stain protection. But you can also seal them anytime later.
Does sealing quartz change the look?
Sealant gives a subtle enhanced sheen but does not alter the color or finish. It makes the counters look refreshed.
Can you seal just part of a quartz countertop?
Sealant should be applied evenly across the entire surface for the best coverage. Don’t try sealing only sections.
How long does quartz sealer last?
With light use, sealant can last 1-2 years. Heavy-use surfaces may need to be resealed after 6-12 months.
What happens if quartz is not sealed?
Unsealed quartz is still stain resistant, but may be more prone to damage and abrasion over time. Sealing is recommended for optimal longevity.
Conclusion
Although quartz countertops do not require sealing, applying a penetrating stone sealer provides extra protection and enhances the look of your counters. For best results, use a sealant made specifically for engineered stone and reapply every 1-2 years. Regular sealing keeps quartz counters looking flawless and easier to clean over the years. With proper care, your beautiful quartz counters can stay looking new for decades.
