Product Information
Safety Datasheet


ARDEX A 18 is a green powder with aggregates and specially formulated additives which, when mixed with water, produces a slurry ideal for bonding ARDEX Screed Cements.

The bonding slurry changes colour as it dries, indicating if it remains open to receive the ARDEX Screed Cement.


  •  Produces a slurry ideal for bonding ARDEX Screed Cements
  •  High adhesion strength maximises the bond between the screed and the substrate
  •  Colour change reduces the risk of the application of screeds into dry bonding slurries
  •  60 minute pot life
  •  15 minute open time
  •  For internal and external use


ARDEX A 18 is used for producing bonding slurries for application over concrete and cement/sand screeds. It is suitable for internal and external use, including swimming pools.

ARDEX A 18 can also be used for joining daywork joints when a new bay is laid against a set and hardened screed, including screeds with underfloor heating systems.
