FLEXIBLE GREY ADHESIVE MORTAR KGF 65
Murexin KGF 65 is a reinforced adhesive designed for installing natural stone, tiles, and porcelain stoneware both indoors and outdoors.
Thanks to its flexible and fiber-reinforced formulation, it offers excellent adhesion and very good deformation capacity, particularly suitable for substrates subject to thermal variations or slight movements.
KGF 65 is particularly suitable for:
- natural stone and tiles,
- travertine and outdoor paving,
- large formats,
- installation over old tiles,
- and heated floors.
Its consistency also allows it to better absorb small irregularities in the substrate while ensuring good adhesive transfer under the elements.
This adhesive is designed for more technical configurations where a standard adhesive reaches its limits: large formats, thermal constraints, renovation, or more demanding substrates.
