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.

The frequency for sealing marble countertops depends on several factors, including the quality and color of the stone, the type of sealant used, and the amount of traffic the surface receives. Marble has a porous surface that requires sealing to maintain its shine and resist scratches. As a general rule, you should seal countertops at least once a year. However, for heavily used surfaces, like those in a busy kitchen or family bathroom, you may need to reseal them every three to six months. Conversely, countertops in a rarely used guest bathroom might only need resealing every few years.

Quartzite is more expensive than granite, largely because of its rarity. Granite is naturally more common. A granite slab generally costs $40 to $60 per square foot (excluding super-rare types), while quartzite slabs cost anywhere from $50 to $150 per square foot. 

With both materials, it’s usually more affordable to purchase stones that are readily available in your location. You may need to import other stones, which come at a higher cost.

The short answer is yes. A stone-safe, pH-neutral cleaner and a soft cloth are all you need to clean and maintain terrazzo. Harsh cleaners aren’t necessary. You can also apply stone polish every few months to refresh your terrazzo.  

It’s recommended that you clean your terrazzo countertops daily to remove dust before it begins to build up. Dust and other debris can cause small scratches over time. If you spill something, be sure to clean it up immediately before stains set in.
