Impregnating Sealer

All natural stone is porous, some more than others. Depending on the porosity of the stone and where it is located, sealing the stone may be recommended. An invisible sealer will fill the pores to inhibit potentially staining liquids from being absorbed into the stone.

Enhancing Sealer

Color enhancing sealer is designed to bring out the color in certain natural stones while offering excellent protection. If you like the color of your slate, travertine, flagstone, etc. when it gets wet, then enhancing sealer may be the option for you.
