Sealing granite countertops is generally recommended to help protect the stone and maintain its appearance over time. Granite is a natural stone that is porous to some degree, meaning it can absorb liquids and stains if not properly sealed.
Here are a few reasons why sealing granite countertops is advisable:
Stain resistance: Sealing creates a protective barrier on the surface of the granite, making it more resistant to staining. By sealing the pores of the stone, it reduces the chances of liquids, oils, and other substances penetrating the surface and causing permanent stains.
Moisture resistance: Granite is susceptible to absorbing moisture, which can lead to damage, discoloration, or even the growth of bacteria or mold. Sealing helps to minimize moisture absorption, protecting the stone from potential harm.
Enhancing longevity: Regularly sealing granite countertops can help extend their lifespan. By preventing stains and moisture damage, the sealed surface is better preserved, maintaining its original appearance for longer.
Ease of maintenance: Sealed granite countertops are generally easier to clean and maintain. The sealed surface makes it more resistant to dirt, grime, and spills, allowing for easier cleaning and reducing the likelihood of stains or discoloration.
It's important to note that not all granite countertops require the same level of sealing. The porosity of granite can vary depending on the specific type of stone and its finish. Some granite may be more resistant to staining and moisture absorption naturally, while others may require more frequent sealing.
To determine if your granite countertop needs sealing, you can perform a simple water test. Place a few drops of water on the surface and observe how it reacts. If the water beads up and remains on the surface, it indicates that the countertop is adequately sealed. However, if the water is absorbed into the stone and causes darkening, it suggests that the countertop requires resealing.
It's recommended to consult with the manufacturer or supplier of your granite countertop for specific sealing recommendations and to follow their guidelines for maintenance and resealing intervals.
