Quartz countertops are popular choices for kitchens and bathrooms due to their durability, aesthetic appeal, and low maintenance. Unlike natural stone, quartz is non-porous, so it does not require sealing to prevent stains from being absorbed. However, some homeowners still prefer to seal their quartz counters for added protection and peace of mind. Here is a detailed look at the pros and cons of sealing quartz countertops to help you decide if it is right for your home.
What is Quartz?
Quartz countertops, sometimes called engineered stone, are made from ground quartz crystals combined with resins and pigments. The resins bind the quartz particles together to form a hard, non-porous surface.
- Quartz is one of the hardest minerals, making countertops very durable and scratch-resistant.
- Quartz counters are stain-resistant since the material is non-porous.
- The resins allow quartz to be molded into different colors and patterns.
- Quartz requires less maintenance than natural stone.
Should You Seal a Quartz Countertop?
Since quartz is non-porous, sealing is not required to prevent stains. Liquids and oils will bead up and sit on the surface rather than soak in. However, some homeowners choose to seal their quartz counters for extra protection.
Pros of Sealing Quartz:
- Adds a layer of protection from stains and etching.
- Makes the countertop more stain resistant.
- Gives the surface a glossy, fresh look after sealing.
- Sealer fills in micro-scratches and reduces their appearance.
- Easier to clean up spills before they dry.
Cons of Sealing:
- Countertop is already highly stain-resistant without sealer.
- Adds an unnecessary expense if sealing frequently.
- Too much sealer could give the surface an uneven, sticky feel.
- Reapplication is required every 1-2 years for continued protection.
- Sealers can react with cleaning products like bleach.
How to Seal a Quartz Countertop
If you opt to seal your quartz, use a sealer specifically designed for engineered stone. Look for water-based acrylic sealers. Avoid solvent-based sealers as they can damage the resin in the quartz.
Follow the product directions closely and test in an inconspicuous area first. Here are some general tips:
- Clean the countertop thoroughly before sealing.
- Apply sealer evenly with a clean cloth or foam applicator.
- Allow the recommended drying time before use.
- Reapply sealer every 1-2 years for optimal results.
Avoid using waxes, oils, or soaps on the countertop surface as they can prevent proper sealer adhesion. Harsh chemicals like bleach should also be avoided as they can break down sealers over time.
Maintaining a Quartz Countertop
Basic maintenance is required whether you seal your quartz or not. Follow these care tips:
- For everyday cleaning, use a mild soap and water.
- Rinse thoroughly after cleaning to prevent residue buildup.
- Blot spills quickly to prevent staining.
- Avoid abrasive cleaners or scouring pads.
- Use a cutting board to protect the surface.
- Don’t place hot pans directly on the quartz.
Is Sealing Quartz Countertops Worth it?
Sealing quartz provides an added layer of protection, but comes with drawbacks like cost and maintenance. Ultimately, the decision depends on your preferences. If peace of mind is important, then sealing may be worthwhile. But sealing is not essential to enjoy the benefits of quartz counters. Proper cleaning and care is the best way to keep quartz looking beautiful for years. Consult with your countertop provider to see if they recommend sealing your particular quartz material.
