Do granite countertops really need sealed?

As discussed in a previous post, natural stone countertops are porous. This means that with all the microscopic holes your natural stone countertops and tile can absorb liquids and other materials if it isn’t properly protected. Some stones are more porous than others and when acidic liquids get absorbed by an unprotected countertop this can weaken and dissolve the stone resulting in fractures or breaks.
In the world of countertops, marble is the most porous followed by granite and the least porous is quartzite. That being said, they are still porous enough to be in need of protection. How do you protect them? Tune in for the next post or give us a call.
