With an initial bond time of around 15 minutes, storey height panels of masonry can be achieved in one lift and structurally loaded within 102 hours.
Celfix is supplied by H+H, dry in 25kg bags and should be added to water (approximately 4.5 litres per bag). Applied with either a scoop or sledge to maintain a consistent joint thickness of 2mm, it remains workable within the bucket for several hours.
When working in winter conditions, it is possible to lay Celfix Mortar in temperatures of 0oC and rising.
Approximate yield per 25kg bag - 2mm joints
