Ready-to-use jointing mortar for ceramic tiles and narrow joints

A-Joint® Ready Flex is a vacuum-packed, ready-to-use jointing mortar for pavements.

Thanks to the fine sand grains and excellent slurry properties, the mortar is perfect for narrow joints from 3 mm.

The jointing mortar is resistant to both frost and de-icing salt. Cracks are avoided thanks to the permanent flexibility after curing. This also makes the product ideal for jointing large tiles on terraces and pathways.
