One Flex

What is One Flex?

One-flex is a high tech single-component, high-performance, polymer-modified thin-set mortar for interior and exterior installations of tile. This mortar has a high content of unique dry polymer, resulting in excellent adhesion to the substrate and tile. Formulated with low-dust technology, one-flex reduces dust by 90% during pouring and mixing, resulting in a cleaner environment. Advanced, high-performance adhesive, with an excellent adherence and flexibility, suitable for the most difficult installations, like high traffic floors, radiant heating floors or façades. Its performance and ease of application make it the ideal solution for the most demanding professionals. Specially recommended for laying rectified tiles.
