In its natural form, granite is already strong, durable, and attractive. However, despite having a low permeability, granite that has not been sealed properly can embed germs and moisture, which are variables that do not bode well on food preparation surfaces. It is important to properly clean and maintain granite countertops.
Frequency of Sealing and Why It’s Important
Because granite is a natural stone and is generally penetrable within its porous surface, sealants are an easy and effective way to protect granite countertops. Some people seal their granite countertops once every six months to a year, though stone can never be oversealed. The best way to tell when you need to seal your stone is to test it. As there are varying guidelines, it is important to pay attention to the condition of your granite. One test for determining whether or not your countertops need sealant is to add several drops of water on top of the granite, in several locations. Let it sit for 30 minutes. If the water has penetrated the surface within and has darkened the granite, it is time to reseal. Other indicators include dull places on otherwise glossy countertops. Paying attention to the duration between the first couple of reseals can help you set a schedule for future maintenance.
How to Seal Granite Countertops
Sealing granite countertops is a relatively quick and simple process with the right preparation and research. Make sure to give yourself about 24 hours of curing time once the sealant has been applied. If you want to do a second coat, adjust your downtime accordingly. You will need gloves, proper ventilation, and plenty of dry clean cloths. Choose a reputable, high-quality granite sealant product such as Granite Gold Sealer®.
Take this opportunity to deep clean your granite using a high-quality specially formulated stone cleaner. When the countertop is thoroughly cleaned and dried, apply the sealant liberally in a 3-foot section. Immediately wipe the sealer into the stone with a dry, lint-free cloth, as leaving it to dry can cause hazing. Use a circular motion when wiping to avoid using excess sealant. Repeat the process 2-3 times for maximum protection. When the product has been adequately applied, leave it for 24 hours before finalizing the process with another cleaning.
