Natural stone, to seal or not to seal?

Natural stone, to seal or not to seal?

You have beautiful new stone work now protect it. Over time, moisture migrates through porous natural sandstone, brick and travertine leaving efflorescence, (white salt deposits on the surface) and surface spalling, (delamination of the top layer of stone).  The grout between the stones is subject to freeze thaw cycles and the accompanying expansion and contraction degradation leads to loose stones.

To prolong the life of the stone and the grout we recommend two coats of non-enhancing (no shine) Dry Treat® impregnating stone sealer and a coat of Stain Proof® non-enhancing stain retarder. When properly installed these products change the surface chemistry of the stone and mortar and give you fresh looking stone work for years to come. This premium solution is like no other product available.

As an option we can install one coat of a natural stone impregnator. Other sealers only sit on top of the stone and have to be re-applied annually. Unlike a topical sealer that will not last, impregnators soak into the stone and grout and repel moisture while allowing water vapor to evaporate. You get similar moisture and salt protection, a non- enhancing product, but not a long lasting solution. Consider this approach a good solution.  Expect to reseal in about three years.
