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.
If you’re considering purchasing a plaster sprayer, then you’ll no doubt be wanting to know whether it’s worth the investment. What’s involved and how much time will it save are the questions that every professional plasterer wants to know the answers to, below are the plaster sprayer types for reference.
Four main types of plaster sprayers:
Pneumatic Sprayer (hopper sprayer gun DP-CH100)
Most common and simple to use. These sprayers have a hopper which holds the material which is connected to an air compressor. The air moves through the bottom of the hopper forcing the plaster out via the outputs on the wall. These tools generally are very simple to use, it only requires an air compressor and an air hose, and easy to clean and cheap price.
DP-CH100 can be used for applying plaster, small scale shotcrete, papercrete, earthen mixes and more. It can be used for plastering a stucco house, traditional plastering of stucco’s such as one coat or three coat stucco, GFRC, stamped concrete you can also use it for a stucco fence and also helps in building organic sculptures.
Item No.: DP-CH100
Recommended air compressor pressure: 6-8bar
Recommended Air compressor capacity: more than 600L/min air output, motor power 4-5.5kw
Carton box package.
N.W. 2.5kgs Measurement: 83*31*29cm
Spraying distance to the wall: 30cm
Max. spraying volume: 25L/min
Screw pump (DP-T3 DP-T7 DP-N1)
These sprayers have a screw pump like DP-T3 DP-T7 DP-N1 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.
DP-T3 DP-T7 DP-N1 Plaster Sprayer With Screw Pump is a new, compact texture spraying equipment unit equipped with Stainless steel hopper, for all textured plasters, cement plaster, putty, gypsum etc with a grain size up to 3 mm, fillers and EIFS adhesives.

Peristaltic pump (DP-TX450)
There are a few plaster sprayers that have a peristaltic pump which also requires compressed air to produce a spray. These types of plaster sprayer can also spray textured coatings with particle sizes up to about 3mm diameter, providing that they are not solvent based.
DP-TX450 is specially designed Peristaltic Pump for spraying texture, and also for all textured plasters, cement plaster, putty, gypsum etc with a grain size up to 3 mm, fillers and EIFS adhesives, etc.

Piston pump (DP-6337iB)
Newer types of plaster sprayer have a piston pump, which has sufficient pressure to spray smooth (untextured) plaster without compressed air. Full airless sprayer piston pumps are sometimes used to spray smooth plaster, although they are not ideal as the flow rate is too low for volume projects; however, they can be used to spray solvent-based plasters, like DP-6337iB professional electric piston pump with 2500W brushless motor and low position suction valve long piston rod powerful for high viscosity paints materials painting.

With spray gun(1pc tip guard + 2pcs tip #531/#541), 3/8”NPSM*15m hose, 1/4”NPSM*1m whip hose.
The role of the pump is to drive the plaster into the hose in order to deliver a constant stream of plaster. Many professionals prefer to have an additional mixing machine on hand to ensure a constant flow of plaster to enable continual production.
When the plaster has been sprayed on the wall or ceiling, it is laid off with a wide spatula, typically 40 cm wide. This can be mounted on a pole for finishing the ceiling.
