    For ceramic tiles and sensitive surfaces

    Thanks to its fine sand grain and excellent slurry properties, A-Joint® Ready Flex powered by ECCO is effortlessly worked into narrow joints from 3 mm. The mortar is applied with water and leaves almost no binder film behind, which greatly facilitates finishing on ceramic tiles, coated surfaces and delicate natural stone. 

  • Gray stone patio with large rectangular tiles, bordered by green shrubs

    No cracking with large tiles

    Shifting substrates, temperature differences and large-format tiles put traditional joints under strain. A-Joint® Ready Flex powered by ECCO remains flexible after curing, preventing cracks—even with large ceramic tiles on patios, footpaths and cycle paths, or in gardens. 

  • Broom spreading wet cement over gray paving stones on a patio

    Ready-to-use and can be applied in light rain

    Vacuum-packed and ready to use straight away, so no mixing required on site. A-Joint® Ready Flex powered by ECCO cures on contact with air, allowing installation in light rain or damp weather. That gives contractors and installers more flexibility in planning.
