In the stone industry, topical sealers
and impregnators (also known as penetrating sealers) are often confused.
Topical sealers lie on the surface of the stone and provide protection against scratches and etching, but it does so by being a superficial layer and does not allow the natural stone to breathe. Also, topical sealers can alter the appearance of the stone, and require frequent stripping and reapplication.
On the other hand, impregnators are designed to pe*****te the surface and repel water, oil, and dirt from entering the stone. Impregnators can be either
water-based or solvent-base, and rides the resin into the natural stone as a liquid form. When the water or solvent evaporates out of the stone, the resin begins to cure into a solid form in the pores of the stone. But over time, the resin loses its strength and bonding to the stone and eventually evaporates away.
In the end, sealers don't provide absolute protection, but they do extend the amount of time you have to clean up a spill before a stain develops. If a liquid is left on the natural stone long enough, it will eventually
pe*****te and stain the stone.
