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 least porous countertop material is engineered quartz. Made from a blend of natural quartz and resins, it is non-porous and highly resistant to stains, scratches, and bacteria. This makes quartz countertops exceptionally low-maintenance and durable, ideal for kitchens and bathrooms where hygiene and easy upkeep are priorities. Other non-porous options include solid surface materials like Corian, which also offer excellent resistance to moisture and stains.

Yes, you can put hot pots on concrete countertops, but only if they’ve been properly sealed. While the concrete itself is heat-resistant, the sealant may not be, meaning heat may discolor the sealant, so use caution.

The average countertop square footage in a kitchen is 30 square feet, but that number varies widely depending on the size of the kitchen. Some smaller kitchens may only have one stretch of countertop or an L-shape. Larger kitchens can include an island or peninsula and more expansive countertops. When deciding what works best for your home, measure your kitchen countertop and make sure to include countertop cost calculations in your budget.
