We use a premium stone sealant, which can last between 3-5 years, depending on variables. We thoroughly apply the sealer and let it soak in and settle, followed by buffing off any excess product, leaving your surface clean and protected.
We also seal granite countertops with a similar product. It’s especially important to get a good base coat of sealer in your new granite, after which you can purchase a product for normal use which will clean and seal simultaneously.
