I have lots of plastering job (internal and external), does my Mayco ST30 or Putzmeister TK40 works as a plaster pump?? Can they handle plaster? (Like as Schwing SP88 or Putz TOMMY GUN A3) thanks

If you can pump concrete, plaster should be a breeze.

I've never have personally did it but, I watched it done. Use a 1.5" hose, duct tape a air hose to it. Use a small gunite tip. Rig up your mixer to dump unto your pump. I watched a stucco crew do a hotel over heavy metal lathe, must have been 100,000 square feet. They gave it all three coats in a few days. Just one guy spraying it on and a few troweling. They were using one of those worm type pumps. But i'm sure any pump would do. If its slow enough.

that's exactly i think it works, I’ve never shotctrete but i assume if i fix air hose into 1,5 inch plus adjust pump so it could pump on slower speed it going to work. Why it shouldn’t??? all i have now is concrete pumps if any of you knows what i'll need more (nozzle, air compressor........???) please let me know, plus also if you have any suggestions, questions, competent persons addresses..... thanks all in advance
