Today we take a look at whether it’s necessary to seal stone. While it is true that granite countertops are very durable, you still have to maintain them, and take care of them periodically, by cleaning, and also sealing them.
Since stone surfaces are quite porous, they will absorb liquids over time, which, if not taken care of, over time will result in discoloring and staining. Although there are many commercial grade products available on the market that may bring stone back to its original luster, taking simple precautions and regular maintenance can save a lot of trouble and cost.
We seal all marble, quartz, and granite countertops during fabrication. This impregnating substance penetrates the stone clogging most of its pores making it quite impervious to alcohol, juices, soft drinks, cosmetics, cleaners, coffee, food, and even oils. Over time, depending on how heavily the tops are used, this sealer may wear off. Therefore, we recommend that the stone be sealed at least once every 6 months for marble, and at least once a year for granite and quartz. If the countertops are heavily used, then it is recommended that the sealing happens twice a year.
