Quartz countertops are an increasingly popular choice for kitchen and bathroom remodels due to their durability, low maintenance, and stylish appearance. Unlike natural stone countertops, quartz is an engineered stone made from ground quartz crystals combined with resins and pigments. This results in a very hard, non-porous material that stands up well to heavy daily use. But despite its resilience, some homeowners wonder if quartz countertops need to be resealed over time. Here is a detailed look at whether quartz countertops need to be resealed and how to care for them properly.
What is Resealing for Countertops?
Resealing is the process of applying a protective sealant to the surface of natural stone countertops like granite, marble, and soapstone. These types of stone are porous, meaning they absorb liquids. Sealing fills the microscopic pits and cracks in the stone to help prevent stains from sinking in and provides water repellency.
Resealing is needed periodically because sealants evaporate over time. Without a protective top layer, stone countertops would be prone to damage from spills and regular use. The reapplication timeframe varies based on the type and quality of the sealer used, but resealing is typically recommended every 1-5 years for most stone countertops.
Do Quartz Countertops Need to Be Resealed?
Unlike natural stone, quartz countertops are non-porous, so liquids don’t penetrate the surface. Resins bind the ground quartz particles together to form a dense, impervious material. This means quartz does not require sealing or resealing to prevent stains. The color and polish will remain intact for the lifetime of the countertop with proper care and maintenance.
The lack of need for resealing is one of the advantages of quartz over natural stone. Homeowners can enjoy the beauty of quartz without the hassle and expense of reapplying sealant every few years. Quartz manufacturers tout this as one of the major benefits of engineered stone countertops.
Caring for Quartz Countertops
Although quartz does not need resealing, it does require proper cleaning and care to keep it looking beautiful. Here are some tips for maintaining quartz countertops:
- Clean frequently with a mild soap and water. Rinse well and dry with a soft cloth.
- Avoid abrasive cleaners and pads which can dull the surface.
- Blot up spills immediately before they have a chance to stain.
- Regularly apply a quartz countertop cleaner and polish to enhance shine.
- Avoid exposing quartz to excessive heat or prolonged contact with harsh chemicals.
- Use a cutting board instead of cutting directly on the counter.
With routine cleaning and care, quartz countertops will keep their like-new appearance for many years. Taking quick action with spills can prevent etching and marks. Following the manufacturer’s recommendations will help prevent damage.
Signs It May Be Time to Refinish Quartz
Though quartz does not require sealing, it may eventually need minor refinishing if the surface develops etching or abrasions over many years of use. Signs it may be time for refinishing include:
- Visible scratches, marks, or dull spots from cutting or abrasive cleaners
- Etching from prolonged exposure to chemicals like lemon juice or cleaners
- Loss of glossy shine even after routine cleaning
- Noticeable stains that cleaning cannot remove
Refresher kits are available to professionally resurface and polish worn or damaged quartz countertops. This process smooths imperfections, restores gloss, and prepares the surface for a protective wax coating. Refinishing provides a less expensive alternative to replacing older quartz counters.
Can You Seal Quartz Countertops?
While sealing is not required, it is possible to apply a quartz sealer or wax as an option to enhance stain protection and create a glossy finish. The sealer fills in micro-scratches and forms a protective barrier. Waxes and sealers may need to be reapplied every 3-6 months for best results.
Be sure to use a sealer specifically designed for quartz rather than a traditional stone sealer. Check with the manufacturer to ensure compatibility and reapplication requirements. Improper sealing could lead to a cloudy, streaky appearance. With proper sealing, quartz can maintain its polish and minimize everyday wear and tear.
FAQs About Resealing Quartz Countertops
Does quartz need to be sealed when installed?
Sealing is not necessary upon installation. New quartz counters come pre-sealed from the factory. Extra sealing does not provide added protection.
How can you tell if old quartz counters need resealing?
Since quartz does not require sealing, it does not need periodic resealing over time. Refinishing may eventually be needed for surface damage.
What kind of sealer is best for quartz?
Look for quartz-specific sealers, not traditional stone sealers. Consult manufacturer recommendations. Common options are silicone or acrylic-based sealers.
How often should you seal quartz counters?
Do not seal quartz countertops on a regular maintenance schedule. Optional sealing for added shine would need reapplied every 3-6 months at most.
Does it help to seal quartz after cleaning with chemicals?
Sealing is not necessary after chemical exposure. Simply rinse the counters well after cleaning and avoid harsh chemicals to prevent etching.
Is it bad to seal quartz too frequently?
Over-sealing quartz can lead to a cloudy, streaky appearance. Use a sealer sparingly if desired and no more than every 3-6 months unless directed otherwise.
Conclusion
Resealing quartz countertops is not necessary like it is for natural stone surfaces. The non-porous resin composition means liquids do not penetrate quartz counters. Proper cleaning is the primary maintenance required to keep quartz looking its best. Optional sealers can provide added shine and scratch protection but do not need frequent reapplication. With routine care, quartz countertops will maintain their durability and beauty for many years without needing to be resealed.
