Had my lads do a spraying job this morning which was a spray on W, pral only job. It was a favour for a mate. Any it was a gable end about 7m wide and 5m to gutter then the Apex. Because most of it was covered by next doors and only the south facing apex exposed he wanted us spraying from the bottom up. Ok with that.
My lad had just got onto the apex and they had to stop because the air pipe on the gun was becoming blocked as it seems to do every other spray.it was solid so he swapped guns. Then nothing! He apparently then gave up and started to clean out the pipe but it wasnt the pipe the r&s was blocked. So he scooped out the powder and there was quite a lot of moist pral in the mixing zone.
This was a 15m pipe at 6.5m high at speed 10 and 210 water setting. The material appeared to be wet. No idea what the back pressure was.
So my question is do you think it was anything to do with working up rather than down and why does that sodding air pipe keep clogging up so often. Hardy ever got that problem with the 3 phrase.
