CONSMAC PLASTER MACHINE P70RD 

Plaster spraying allows a plasterer to skim a drywall more than five times faster than using a hand float to apply it. Although classic gypsum-based plaster can be sprayed if it is "spray grade," most plaster sprayers prefer the organic-based pre-mixed plaster packaged in a plastic bag because the plaster spraying machine does not need to be cleaned out after the job is finished, providing that plaster is kept moist. The pre-mixed plaster also has the advantage that any surplus can be recycled, almost eliminating waste, and plasterers do not need to haul water and mix the plaster from powder. A drywall skimmed with pre-mixed plaster can be painted in less than 24 hours, depending on the ambient temperature and humidity.

Worm-drive pump

These sprayers have a worm-drive pump like Utiform Quattro or Master that pumps the plaster up to a spray gun that has a large nozzle, usually 4 to 8 mm, that extrudes the plaster into a chamber on the end of the gun. In this chamber, compressed air is introduced to blast the plaster into a spray. Worm-drive pumps have a rubber stator which is not compatible with solvent-based materials.
