Yes, it is generally recommended to seal granite countertops to protect them from potential stains and maintain their appearance over time. While granite is a durable and resilient natural stone, it is still porous to some extent. Sealing helps to create a protective barrier on the surface, reducing the likelihood of liquids and other substances penetrating the stone and causing stains.
Sealing frequency can vary depending on the specific type of granite and the sealant used, but as a general guideline, it's recommended to reseal granite countertops every 1 to 3 years. However, some sealants claim to provide longer-lasting protection, so always follow the manufacturer's instructions for your particular sealant product.
Keep in mind that some granites are more porous than others, so it's essential to be aware of your specific countertop's needs. If you're unsure about the sealing requirements for your granite countertops, it's best to consult the manufacturer's guidelines or seek advice from a professional stone installer or countertop supplier.
In addition to sealing, regular cleaning and proper maintenance will help prolong the life and beauty of your granite countertops. Clean up spills promptly, avoid using harsh or acidic cleaners, and use cutting boards and hot pads to protect the surface from scratches and heat damage. With proper care, your granite countertops can continue to be a beautiful and functional addition to your home.
