FLEX ADHESIVE MORTAR KWF 61
Murexin KWF 61 is a high-performance flexible white adhesive for laying natural stone, tiles and large formats indoors and outdoors.
Its formulation allows for an application thickness of 3 to 20 mm, particularly useful for natural stones with variations in thickness or substrates with slight irregularities.
KWF 61 is particularly suitable for:
- travertine and light natural stones,
- large formats,
- natural stone paving,
- laying over old tiles,
- and underfloor heating.
Its white colour is particularly suitable for light or sensitive natural stones, while maintaining excellent adhesion and very good flexibility.
This adhesive also offers very good application comfort thanks to its formulation that significantly reduces dust emissions during mixing.
KWF 61 is a particularly reliable solution for technical installations requiring more flexibility, correction thickness, and application comfort than traditional adhesives.
