Believe it or not, stones are actually very porous and easily absorb water. Stones such as limestone and sandstone are often included in the construction of homes and buildings. They are used for the exterior veneer of the house and even walkways. Yet because of their very porous nature, the soft stones are also subject to weathering (wind/rain/saltwater) quicker than other substrates.

Salts and deicing chemicals (used in winter areas) will further hasten the degradation of stone walkways. Our Trojan Masonry and Trojan Ultra Sealers will densify and increase the longevity of the stone as well as waterproof the surface permanently.

The below pictures were taken by Dunlap Construction of Duvall, WA who used our Trojan Ultra Masonry Sealer.
"These pictures are taken about four years after a single application. The home is situated about 100 feet off saltwater where the wind blows salt onto the stone walls with virtually no sign of wear. The material is Wilkeson Sandstone cut to my specs and then tumbled. There is approximately 160 tons of stone veneer"- Steve Dunlap
