Additional information




Hey’di Barrier Mortar should be applied to a damp substrate. When using with the K11 system apply a 25 mm fillet into all vertical and horizontal joints. It should be applied onto the first coat of Hey’di K11 before it has cured. This will typically be around 1 hour application of the Hey’di K11, and care should be taken not to damage the underlying coating. Hey’di Barrier Mortar can also be used as a general repair compound for patch filling of masonry wall and floors.
