FlexStone is a composite paneling product that is designed for use in wet-wall bathroom applications, but can also be used for any paneling application. FlexStone is comprised of multiple layers of engineered thermoplastic, a printed image, and a lightweight PVC backing, all bonded using high heat and pressure and a thermosetting bonding agent. The materials used in FlexStone have been UV stabilized and resist discoloration and staining. The image is protected by the substantial clear thermoplastic layers, which also provide an outer wear surface that is non-porous, thereby resisting bacteria, mold and mildew development.

FlexStone is well-suited for bathroom wet-wall applications, such as tub and shower walls, splashes, skirts, trims, shampoo and soap shelves, cubbies and more. Unlike tile grout and natural stone, FlexStone won’t mold or mildew and is easy to clean.

FlexStone is also an excellent choice for other projects, such as wall-cladding, wainscoting, window sills, etc. FlexStone has passed commercial fire testing and is suitable for commercial work as well. FlexStone will perform well in applications demanding light weight with a high-end look. In addition to residential and commercial bathrooms, FlexStone also finds uses in RV’s, manufactured homes, yachts, planes, lobbies and more.

Yes, FlexStone can be installed over existing tile. Remodel Trim Molding will be needed to allow for the extra thickness when installing over existing tile. Remodel Trim Molding is sold separately. If the existing tile has a glossy surface, be sure to rough it up with sand paper before installing FlexStone. This will result in better adhesion of FlexStone to the tile.

FlexStone can be installed over a variety of backer board substrates, including sheetrock, cement board, or even existing tile. Be sure to consult local building codes to determine the appropriate backer board.

Care and maintenance of your FlexStone surround is easy using common household cleaners. Clean with a soft sponge or cloth, and mild nonabrasive cleaners. Often, warm soapy water and a sponge will be adequate for regular maintenance. FlexStone has no grout lines to clean, and is nonporous, so sealing is never required.
