Quartz Countertops: Sealing and Maintenance

Quartz countertops have become increasingly popular in recent years due to their durability, beauty, and low maintenance requirements. One common question that homeowners often ask is whether quartz countertops need to be sealed. The answer is no. Unlike natural stone countertops such as granite or marble, quartz countertops are engineered and do not require sealing.

The Benefits of Quartz Countertops

Quartz countertops are made from a blend of natural quartz stone and resin, which gives them their strength and durability. The resin acts as a sealant, making the countertop non-porous and resistant to stains and bacteria. This means that liquids and spills will not penetrate the surface of the countertop, making it easy to clean and maintain.

Heat and Scratch Resistance

Another advantage of quartz countertops is their high resistance to heat and scratching. This makes them an ideal choice for busy kitchen environments where pots, pans, and knives are constantly in use. Unlike natural stone countertops, quartz countertops do not require regular sealing to protect them from potential damage.

Proper Care and Maintenance

While quartz countertops do not need to be sealed, it is important to note that proper care should still be taken to maintain their appearance. Regular cleaning with mild soap and water is usually sufficient to keep the countertop looking its best. Avoid using abrasive cleaners or scouring pads, as these can dull the surface of the quartz. Additionally, it is recommended to use cutting boards and trivets to prevent any potential scratches or damage.

Frequently asked questions about sealing quartz countertops

Q: How often should quartz countertops be sealed?

A: Quartz countertops do not require regular sealing. However, if you choose to seal them, it is generally recommended to reseal every 1-2 years or as needed based on the condition of the countertops.

Q: Can I use any sealer on quartz countertops?

A: No, it is important to use a sealer specifically formulated for quartz countertops. Using the wrong sealer can result in ineffective sealing or damage to the surface.

Q: Can I seal my quartz countertops myself, or should I hire a professional?

A: Sealing quartz countertops can be a DIY project if you follow the proper steps and use the right products. However, if you are unsure or prefer professional assistance, it is recommended to hire a reputable stone fabricator or installer who has experience with sealing quartz surfaces.


In conclusion, quartz countertops do not need to be sealed due to their non-porous nature and resistance to stains and bacteria. The resin used in manufacturing the countertop acts as a sealant, eliminating the need for homeowners to apply additional sealers. However, regular cleaning and proper care should still be practiced to ensure the longevity and beauty of the quartz kitchen countertop.
