Mapei Keraflex Maxi S1 Grey Standard Set Flexible Tile Adhesive 20kg

Take full control of your tiling project with Mapei Keraflex Maxi S1, a high-performance, standard-setting adhesive for professionals and discerning DIYers who demand a perfect finish. Unlike rapid-set adhesives, Keraflex Maxi S1 gives you an extended pot life of up to 8 hours, eliminating the stress of a ticking clock. This makes it the perfect choice for tiling large floor areas, setting out complex patterns, or meticulously positioning heavy, large-format tiles.
Its two standout features are its incredible thixotropic consistency and its thick-bed capability. The "no vertical slip" formula means even the largest and heaviest porcelain and natural stone tiles hold firm on the wall instantly, allowing you to work from the top down with confidence. A true problem-solver, it can be applied in a bed depth of up to 15mm, allowing you to tile directly onto uneven walls and floors without the need for a separate levelling compound, saving you time and money.
As an S1-rated flexible adhesive, it is the ideal choice for tiling onto timber substrates and over underfloor heating systems, providing a bond that can withstand minor movements and temperature changes
