Cleaning & Sealing Natural Stone


Caring for thin stone is very simple. Since thin stone is completely natural, it's tough and will not peel or chip in most climates. No treatments are required because the colors will not fade or change in the sun. The only recommended steps are periodic inspection and cleaning. During inspection, look for rare cracks or signs of damage, much like what you would do to your windows or existing siding. Cleaning this stone can be done with a low setting on a power washer or by brush. Minor dirt can even be hosed off. It is imperative to not use any type of acid especially muriatic.


Protecting natural stone veneer from moisture, sunlight, and stains is accomplished through the application of a stone sealer. Sealing stone adds a protective layer to your stone, while making cleanup and maintenance much easier. Stone that is installed outside or that will be exposed to moisture, sunlight, or possible stains should be sealed. This sealing helps prevent stains from rain, dirt, or food spills. It also reduces the effects of the sun on the colors of the stone.

Water-based sealers are the most popular since they penetrate the stone more, are easier to apply, and clean up with soap and water. They are usually applied by brush or sprayer, depending upon the surroundings. The surface should be clean and loose chips should be removed. Most sealers will change the appearance of the stone by giving it a darker, wet look. Be sure to test your sealer on some extra stones or an inconspicuous area and allow it to dry before treating the entire surface. Below you can see our Sequoia product with a wet look sealer applied.
