Engineered quartz is an artificial, nonporous material made from a mix of mined ground quartz, polymer resins, and pigments, making it a lower-maintenance option. In contrast, quartzite is a natural stone composed of sandstone, which makes it highly resistant to heat but often requires sealing and more careful upkeep. You should clean both types of stone with non-abrasive cleaners that have a low or neutral pH, avoiding acidic cleaners like vinegar, as well as wire brushes and scouring pads.

The frequency for sealing granite countertops depends on several factors, including the type of sealant used, the color of the granite, and how heavily the countertops are used. As a general guideline, resealing is often recommended every 12 to 18 months, but some sources suggest it could be as often as every few months or at least once a year.

The type of sealant is a major factor: water-based sealants may need reapplication every six months to a year, while more durable solvent-based sealants can last for five to 10 years. Additionally, factors like heavy kitchen traffic, frequent use of acidic cleaners, and lighter granite colors may require more frequent sealing to prevent staining.

To determine if your countertops need resealing, you can perform a simple water test. Place a few drops of water or a wet paper towel on an inconspicuous area of the granite. After 10 to 15 minutes, check the spot. If the water has beaded up, the seal is still intact. If the water has been absorbed and darkened the stone, it's time to apply a new coat of sealant. You can choose to seal the granite yourself or hire a professional to ensure it's done correctly.

A water-based, low- or no-VOC sealer is typically a good choice for marble countertops. Choose a sealant that is certified safe for contact with food when applying to kitchen countertops. For high-traffic areas, look for formulas that have heat-resistant and acid-resistant features. While there are economical and convenient spray-on sealers, they don’t coat the surface as effectively as the ones you apply with a pad or brush. 

Your morning mug of coffee won’t instantly damage your quartz countertop, but it’s still wise to play it safe. While quartz can handle brief heat, repeated exposure can wear down its finish over time. Using a coaster adds a simple layer of protection and helps keep your surface looking fresh.
