Spray plaster

[mbldecs]

Hi. I'm matt, I'm a qualified decorator.  I'm looking at going into spray plastering. I have a graco g max 7900 hd petrol airless paint sprayer which I've been using for the last couple of years to spray paint.  Anyone know whether I can spray plaster with it and what maximum hose length I can use. Or, which machine would be ideal. Any advice would be helpful.

I’ve several spray render pumps 

and one that sprays projection plaster 

Backing and finish together 

Which is handy on office block stairs 

But not worth getting out for less than a 150 m2 per day Base and finish 

Rifina do a sprayer for finish but the amount of work masking  up makes it not worth it and you would still need a couple of spreads to finish it for you
