Your granite or marble countertops have been sealed before completing your job. However, some stones may need additional applications in the future. Every stone differs in porosity. If your countertop becomes darker when wet, it is time to seal. Resealing is a simple process and will not take much time at all. You can find a penetrating, natural stone sealer at your local hardware store or talk to our sales team about the products we offer. Spray on the sealer and let the countertop absorb the sealer. Wipe off the excess and enjoy your newly sealed countertops!
