Seal your stone to resist stains

Sealing: Most natural stones should be sealed with a high quality penetrating sealer. Some granites do not require sealing as the stone is so dense nothing penetrates, not even the sealer. The greater majority do require sealing. Most contaminants that damage your stone are water or oil soluble. Premium quality impregnators that reject both oil and water should be used. By applying this type of sealer, you will have more time to blot up spills before they penetrate your stone’s surface.

A point to appreciate also is that once your stone is sealed, this does not mean it is impenetrable. If a liquid sits on your stone long enough, it can eventually penetrate. This is especially so with very porous stone like Limestone. So wipe up spills immediately. Sealing basically buys you time, so make sure you seal your stone.

Never assume your contractor or installer has sealed your stone. Always ask if it has been sealed and with what type of sealer.

Please also note that although your stone may be sealed, sealing does not prevent etching. Etching is often confused with staining. ie: you spill red wine on your polished or honed unsealed limestone. The wine penetrates leaving an ugly red mark inside the stone. That’s a stain. Etching occurs when you spill red wine on your sealed limestone, you wipe it up, there’s no red mark but there is a whitish blotch left behind and you can see exactly where the wine spilled. That’s an etch mark. This mark can only be removed by a qualified stone care specialist.
