Quality Stone caulking is a textured caulking made to look like grout that is available for all styles and colors of Quality Stone. It is used to cover the heads of screws during the install of Quality Stone. Screws are usually ran through the tongue of each panel but at the top row, the tongue must be cut off and face fastened.
The caulking is used to hide those screws. Quality Stone caulking is also used during the install of ledge and edge trims and to provide a finished, grout-looking appearance to any part of the install.
