MasterTile FLX 23 - Flexible tile adhesive for all ceramic tiles, porcelain mosaic and fully vitrified tiles

How does MasterTile FLX 23 work?

MasterTile FLX 23 is a polymer modified pre-bagged single component cementitious tile adhesive requiring only the addition of water and mixing to make it ready for use. MasterTile FLX 23 has been carefully formulated to attain optimum non-sag properties, adjustability and open time of the applied product. The use of specialist polymers ensures that adequate adhesion is guaranteed even in difficult conditions such as under water. Once applied and cured MasterTile FLX 23 is resistant to service temperatures ranging from -30°C to +80°C.

MasterTile FLX 23 meets the classification requirements C2TE of EN 12004.
