Quartz countertops are an increasingly popular choice for kitchen and bathroom remodeling projects thanks to their durability, aesthetics, and low maintenance. However, some homeowners wonder if they need to reseal quartz counters periodically like other natural stone surfaces. Here is a detailed look at whether quartz countertops need resealing.
What is Quartz?
Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with resin, pigments, and other compounds. The result is a man-made material that is much harder and less porous than natural stone.
Key traits of quartz:
- Extremely durable and scratch-resistant surface
- Non-porous so resists staining
- Available in wide range of colors and patterns
- Does not require ongoing sealing
Quartz offers the aesthetics of natural stone with maximum durability and easy care, making it an ideal choice for busy kitchens.
Do You Need to Seal Quartz Countertops?
The short answer is no. Unlike granite, marble, and other natural stone countertops, quartz does not require sealing.
Here’s why:
- The resin binders mixed with the ground quartz fill in any natural pits and cracks that could absorb liquids.
- The non-porous surface repels moisture.
- Stains have a difficult time penetrating the dense material.
Reputable quartz manufacturers will pre-seal the slabs during production. They also polish the surface to a smooth, consistent finish that further prevents absorbing.
So quartz counters are impervious right out of the box. The sealed surface will last for the lifetime of the countertop with proper care.
Pros of Not Resealing Quartz
The fact that quartz never needs resealing provides several advantages:
- Saves time and effort. No need for periodic reapplication of sealants.
- Lower maintenance. Counters stay looking like new with simple cleaning.
- Cost savings. No expenses for sealants and application tools.
- Consistent appearance. Sealing can slightly darken some natural stones.
Quartz’s non-porousness gives it excellent stain resistance and durability without on-going sealing requirements.
How to Care for Quartz Countertops
While quartz does not need sealing, proper cleaning and care is recommended to keep counters looking their best:
- For everyday cleaning, use mild soap and water.
- Blot spills quickly to prevent any staining.
- Avoid abrasive cleaners and scouring pads that may dull the finish.
- Use a gentle granite cleaner to remove stuck-on dirt.
- Disinfect periodically with diluted bleach.
- Rinse thoroughly after cleaning.
Avoid exposing quartz to strong chemicals like paint removers, oven cleaners, etc. Read this guide for more quartz care tips from the experts.
Signs Your Quartz Countertops Need Resealing
Since quartz does not need sealing when properly maintained, there are not really any signs that resealing is required.
However, if stains start absorbing rather than sitting on the surface, it could indicate wear to the original factory seal, especially in heavy use areas. Possible signs of this include:
- Noticeable darkening of the quartz at certain spots
- Spills and stains becoming harder to remove
- Increased surface etching and pitting over time
In such cases, resealing may help improve stain resistance. Consult a countertop professional to assess whether your quartz counters could benefit from an added sealant.
Can You Apply a Top-Up Sealant to Quartz?
While quartz manufacturers state their products never need sealing, some homeowners wish to apply an optional top-up sealant for extra surface protection and easier cleaning – especially for heavily used kitchen counters.
The key is using a sealant specifically formulated for quartz rather than products intended for natural stone:
- Quartz sealants contain smaller molecules that penetrate well.
- Look for water-based formulas without solvents.
- Select non-toxic, food-safe products.
Follow application directions carefully. Put on multiple thin layers allowing proper drying time between coats.
A high-quality quartz sealant can provide extra protection without altering the look. But for most homeowners, the factory seal is adequate for the lifetime of their counters with simple care and maintenance.
Quartz Countertop Sealing FAQs
Should I seal my new quartz counters before use?
No, pre-sealing is not necessary. Manufacturers seal quartz properly before installation.
How often does quartz need sealing?
Never. Quartz is non-porous and the factory seal lasts a lifetime.
What is the best sealer for quartz countertops?
Look for sealers specifically designed for quartz rather than stone. Popular options include Tenax Hydrex and Miracle Sealants 511 Porous Plus.
Can I use a granite sealer on quartz?
No, granite sealers can discolor quartz. Always use a quartz-specific sealer.
Conclusion
Unlike natural stone surfaces, quartz counters do not require routine sealing thanks to their non-porous composition. The durable, factory-applied seal protects from stains and moisture. Avoid abrasive cleaners that could damage the surface. With simple care, quartz countertops will stay looking new for many years without needing resealing. An optional reapplication of quartz-specific sealant can offer added protection for heavy-use areas if desired.
