A brief guide to post-sealing surface protection
Anyone who's ever used a Dry-Treat sealer, such as STAIN-PROOF Original™, knows you're dealing with a reliable and highly effective product. As far we're concerned, if you haven't sealed your stone with one of Dry-Treat's line of impregnating, breathable sealers, your stone doesn't have proper surface protection in place.
But there's a tendency among those not as versed in natural stone to view sealing it as the one and only thing they need to do to keep it protected. Not so, unfortunately – taking care of your stone is a full-time job, and there's only so much a sealer can do. You'll continue to have to take good care of your surface in a number of ways.
Wipe up spills
There's a misconception that, because impregnating sealers prevent water and other substances penetrating the stone, they are completely impervious to penetration. But because these sealers are breathable – or maintain open pores to allow moisture underneath the stone to escape – spills can still get into the surface if given enough time.
To combat this, remove any and all spills as soon as you see them, rather than relying on your sealer to keep them at bay. The Marble Institute of America recommends blotting the area with a paper towel rather than wiping, and subsequently flushing the area with mild soap, before rinsing and drying with a soft cloth. You can also use Hanafinn Oxy-Klenza™ if you want to be sure.
Keep the area spotless
Sealers may prevent oil and water from getting in and sealing your stone, but your stone is not suddenly invincible. It can still be physically damaged by various items, leaving scratches and other unsightly marks.
Be sure to vacuum and sweep your surface regularly to keep it free of any scratching particles, and make use of mats and rugs, making sure their underside is made of a slip resistant surface. Be careful, too, with wheels on furniture and other items, which can also damage your stone.
Be careful with acidic substances
Stone and acid simply do not mix. If an acidic substance like lemon juice, wine or vinegar gets on your stone, it won't take long before it causes acid etching on it – and it won't matter if you've sealed it or not.
This is particularly likely on calcareous stones, metamorphic rocks mainly composed of calcite. Because calcite reacts with acid, all it takes is physical contact between the two to lead to fireworks. If you can, try and keep acids away from these kinds of stones, or at the very least wipe up spills as quickly as possible.
