did a spray mate but limped to the finish really.....things started off well but we were spraying a bit dry so i expleted off the scaff to the lab to lower the pressure on the mortar pressure gauge to closer 20 bars as we had 20m of pipe on and much to my bemusement it felt the gear just wasn't getting any wetter. In fact it was getting dryer, the daft apeth was only lowering the water to lower the back pressure!! Bear in mind the physics of this was all explained before powder touched water as with the arrival of our new flagship machine, a certain upping of the game was necessary by all members of staff and we were gonna take it to 'the next level'. Suddenly realising the error of his ways, panicked and cranked the water up and in so doing managed to bridge the hopper and from then on we were doomed, doomed I tell you as we didn't know what was happening. All in all a complete disaster.
After explaining this circus of events to les the error of our ways or sheer incompetence if you like became clear. sorry mate i'am new, what machine do you have?? iam going to ptf tommorw to have a look at there machine's ;D
