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.

There are several countertop options available to fit your lifestyle and needs. 

• Granite countertops are durable and come in a variety of colors.

• Soapstone countertops are prone to scratches and best in smaller kitchens.

• Marble countertops are less durable than granite but a good option for busy kitchens.

• Slate countertops are stain-resistant, making them easy to clean.

• Limestone countertops must be sealed often to prevent scratches.

• Acrylic countertops cost less than granite while still providing durability.

• Laminate countertops are the most affordable but chip and fade faster.

• Wood countertops need monthly sealing to maintain.

New countertops can last for anywhere between 15 and 50 years, with the exact lifespan depending on the material:

• Quartz: 50 to 100 years

• Marble: 50 to 100 years

• Granite: 50 to 100 years

• Laminate: 15 to 20 years

• Concrete: 20 to 30 years

• Tile: 40 to 100 years

Keep in mind some materials are more likely to stain and chip than others, which is an important factor to consider when it comes to the longevity of your countertops. Some materials also need special cleaning and maintenance, like tile countertops, which need grout cleaning, and concrete countertops, which need resealing.

The resin should be periodically sealed to help prevent it from wearing down or becoming porous. Very sharp or very hot objects can damage the resin surface, and there’s no way to fully repair it if that happens, so we recommend treating the counters well.
