But limestone sealants MUST allow oxygen to penetrate the sealant barrier so that the stone can breathe, while providing maximum coverage to the nooks and crannies in the porous surface.

Without oxygen, limestone will begin to deteriorate quickly. We make two types of sealant that are appropriate for finnicky limestone. One of our favorite limestone sealers is TSSPRO 200. It’s ideal as a lueder’s limestone sealer, providing deep penetration and unparalleled protection to the porous stone. TSSPRO 700CS is our best limestone sealer for ultimate protection, especially if you’re concerned about water penetration, mold growth, mildew stains, or fire damage. That’s right, it’s waterproof and fireproof! While it works well on lueders, it’s also recommended for Austin stone (a.k.a. Austin limestone).
