I have a three storey Georgian town house to re plaster, 3m ceiling hieghts and large stairwell, it's all 9" brickwork and was previously done in lime of course, it's been priced for harwall but I think CPI might be a better option, there is a fair depth to go on walls in places, you know the craic, scratch float and skim. Will CPI go through ritmo OK and will it pump 30m through a G4? Any advice appreciated.
