Quartz countertops are an increasingly popular choice for kitchen and bathroom remodeling projects. Made from ground quartz crystals combined with resins and pigments, quartz offers an attractive, low-maintenance, and durable surface. However, quartz is not completely impervious and proper sealing is an important part of maintaining its beauty and function. This article will discuss the best sealants to use on quartz countertops.
Why Seal Quartz Countertops
There are a few key reasons to seal quartz countertops:
- Prevent stains: Quartz is non-porous, so it resists stains better than natural stone. However, it is still possible for spills, grease, and dirt to leave stains if left for prolonged time. A sealant provides an added layer of protection.
- Ease cleaning: Sealant fills in micro-pores and creates a smoother surface. This makes routine cleaning easier as grime has difficulty adhering.
- Retain shine: A sealant can enhance the glossy factory finish of quartz. It keeps the vibrant appearance longer.
- Avoid damage: Sealant forms a protective barrier against chemical etching from acidic foods and abrasion from sharp objects. It also reduces moisture penetration.
What to Look for in a Quartz Countertop Sealant
When selecting a sealant for quartz, consider these factors:
- Compatibility – Ensure it is designed for use on engineered stone like quartz.
- Penetrating formula – Will soak in rather than leave a surface film that can yellow over time.
- Non-toxic – Low odor and VOC-free. Many are food-safe once cured.
- Ease of application – Choose a product that goes on smoothly and buffs to an even shine.
- Durability – Long-lasting protection, often over a year with just one application.
- Enhance shine – Opt for a sealant that will enhance the glossy sheen.

How to Seal Quartz Countertops
Sealing quartz countertops is a relatively simple process, but proper preparation is crucial:
- Clean counters thoroughly with a pH-neutral cleaner to remove any dirt, residue, wax or oils. Rinse and let dry completely.
- Mask off any adjacent surfaces like walls, cabinets, and floors to avoid getting sealant where it’s not wanted.
- Apply sealant according to manufacturer instructions. Typically dispensed on a cloth and rubbed into the surface using circular motions. Allow to soak in for 5-10 minutes.
- Thoroughly buff off any excess sealant with a clean cloth to prevent residue.
- A second application may be recommended for optimal protection. Wait the suggested time before using the surface.
- Avoid water or cleaning for 24 hours to allow the sealer to fully cure.
Sealing is recommended every 1-2 years for quartz countertops in the kitchen. Promptly address any etched or damaged areas. With proper care, quartz countertops will remain beautiful and functional for years.
Frequently Asked Questions About Sealing Quartz Countertops
Should new quartz counters be sealed right away?
It is a good idea to seal brand new quartz counters during initial installation or shortly after. This helps extend the factory finish and prevents early staining or etching. Check with your fabricator, as some provide an initial sealing.
Is sealing absolutely necessary for quartz?
Sealing is highly recommended to prevent damage, stains, and bacteria growth. Unsealed quartz is more prone to etching and dulling over time. However, sealing is optional especially for low use areas.
How long does a quartz countertop sealant last?
On average, sealants last 1-2 years with normal use. Higher quality options like BulletProof can last 5-10 years with just one application. Duration depends on wear and whether the surface is prone to heavy use or abuse.
Can I use a granite sealant on quartz?
Generally it is best to use a sealant specifically formulated for engineered stone. However, certain premium granite/natural stone sealants also work well on quartz. Check if the product specifies it can be used on quartz.
Should I seal the quartz sink and quartz backsplash too?
Yes, it is recommended to use the same sealant on quartz sinks, integrated sink areas, and backsplashes. This provides complete protection and avoids having noticeably different surface appearances.
Conclusion
Sealing is an important maintenance step for any quartz countertop installation. The right sealant will help prevent stains and etching, simplify cleaning, retain shine, and extend the life of your counters. Be sure to use specialty products designed for engineered stone and apply according to manufacturer guidelines. With proper sealing, you can enjoy beautiful, worry-free quartz countertops for years to come. Regular sealing provides peace of mind against any damage or deterioration of your investment.
