Designed for both vertical and horizontal applications, it is ideal for repairing concrete floors, screeds, concrete steps, ramps, coves and patching around pipework, doors and window frames. Thanks to ARDEX ARDURAPID Technology, the mortar sets in approximately 15 minutes and receives floor finishes after just 90 minutes, regardless of thickness.
