CARE GUIDE:

Apply Sealant :

Natural-stone sealant can be sprayed right on the countertop and wiped to ensure it penetrates the surface through the pores. Spray the sealant in 3-foot sections and work it in before it dries. Make sure to use a lint-free cloth and apply a buffing motion that lets you see the sealant being absorbed.

If the surface where you poured the water shows any discoloration or darkness compared to the rest of the counter, then it's time to reseal the countertops. Most stone experts recommend sealing your  countertops every 3-6 months.
