A-Joint® Ready Flex is the ready-to-use grout for ceramic tiles and narrow joints from 3 mm. Thanks to the fine sand grain and lasting flexibility, no cracks occur.

  • Light beige patio tiles with a border of greenery and purple shrubs in the garden

    For ceramic tiles and sensitive surfaces

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

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

    No cracking with large tiles

    Shifting sub-bases, temperature fluctuations and large-format tiles put traditional joints under pressure. A-Joint® Ready Flex powered by ECCO remains flexible after curing, preventing cracks—even with large ceramic tiles on terraces, foot and cycle paths, or in gardens. 

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

    Ready-made 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, making installation possible in light rain or damp weather. This gives contractors and installers more flexibility in scheduling.
