Fortunately, there are many types of heatproof countertops. Granite, quartzite, concrete, and stainless steel are all fiery contenders. These surfaces work best in busy kitchens where hot pots, pans, and baking sheets are part of the daily routine. Plus, their durability means you get a long-lasting work surface that won’t flinch at a bit of heat or heavy use. However, many stone and concrete counters require a sealer, which is typically not heatproof.

Resurfacing countertops is relatively easy—especially for a pro. During this process, a countertop contractor will sand down or remove the existing countertop surface, make repairs, and then add a new surface or special coating. In certain instances, like if you use a laminate countertop coating system, it’s an attainable DIY for beginners.

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.

When installing an undermount kitchen sink in a granite countertop, use 100% silicone to secure the basin. If you’re worried your sink is too heavy, speak with a countertop professional about how to adhere the sink to the countertop without worrying about issues down the road. Sagging undermount sinks can be a common plumbing problem if they’re not properly adhered, so always make sure you’re using a high-quality material.
