There is currently no penetrating sealer that can stop etching on calcite based stones.
On Absolute Black granite etching causes gray rings and spots on the surface. A topical sealer is not recommended
for natural stone because it blocks the pores of the natural stone then can't breathe and the top coating can scratch easy.
So what happens to natural stone that can't breathe? Moisture gets trapped and can cause a chemical and mineralogical
change within the stone. This action of decay in natural stone may take form of pitting, spalling, flaking and oxidation.
You want your natural stone to breathe or it will disintegrate.
