So what is the truth about stone impregnating sealers? Do you really need them? What do they do? More importantly what don’t they do?
In the last 10-15 years, there has been a rise in the use of impregnators (sealers) for use on natural stone. What also occurred during this time is that more and more people have been able to afford marble and other natural stone in their homes instead of ceramic or laminate. Unfortunately, although the stone often looks great, it is not always the best type of stone for a kitchen or a bath, and thus gets stained and scratched.
So what can a sealer do to prevent this problem? Natural stone is porous. When you spill white wine or spaghetti sauce on a white countertop it is going to absorb somewhat. If you have applied a sealer, it will not absorb thus saving your countertop from staining.
It is important to mention, however, that sealers will NOT prevent scratches or etch marks caused by some type of caustic substance. Lemon juices, some personal hygiene items, and household cleaners can often mar the surface of marble or stone. Sealers will NOT prevent this from happening. You must try to immediately wipe up the spilled product and make sure you use a pH neutral cleaner specifically formulated for natural stone.
