We used the Dustless Blaster to remove rock hard dried mortar from a mortar mixer
with surprising efficiency.The Dustless Blaster was many times faster
than a needle scaler for this job.because of botuolini machine BL-08200  
with 8litres per minutes water flow and 2000bar/29000psi pressure. 

So ,removing dried mortar is not so difficlult for you anymore.
