Care & Maintenance

Do my granite counters need to be sealed? Some people say yes and some say no.

It depends. If this was the late 1990s the answer would have been an emphatic yes, but things have changed, stone processing processes have improved. While no one "makes" natural stone, they do run it through a series of processes to convert it from a rock, to a slab, to a counter or tile. When the granite is cut into slabs today, most of it is now being "resinated", whereby a polyester resin is vacuumed through the stone. The resin fills the natural pores present in every stone. This is done to improve the slabs transportability. If not done, many of the unusual colored stones, would not survive the shipping process, cracking and shattering enroute. The resination imparts improved flexibility to the slab. As a side-effect, but filling the pores, resination effectively seals the stone. Today, most granite is being resinated and therefore does not need to be sealed. If your counters are older than 5-years and you do not KNOW that they have been resinated, you will want to have them sealed every other year. Sealing is fairly inexpensive, and is certainly MUCH less expensive than the time, cost and annoyance of having to have a stain removed.
