You might be in shock but as any other construction method, so does the plaster application. Plaster can be applied through intended spray machine. Plaster spraying allows you to give a finished look without the need of a hand float. The process of spraying plaster can be quicker than by hand but can give you the same, or even better quality of plaster finish.
Plaster spraying provides faster work with lesser workers involved, can be more consistent once mastered with the right equipment and mixture ratio and can cure faster than the traditional way of plaster application. Plaster spraying also has lesser chances of cracks due to faster curing which means lesser shrinkage.
Spray plaster can be of smooth finish for a sleek and neat look of the surfaces, textured and colored finish which gives your surface appealing depending on your aesthetic.
Spray plastering can be done in different types. It can be through a pneumatic sprayer which is the most common and easiest to use. It only requires an air pressure and air hose to do the job.
Next is, screw pump which the plaster is pump into the spray gun with a large nozzle where the plaster will pass through. These pump is not suitable for solvent-based materials as it has rubber stator.
Another would be peristaltic pump which has a peristaltic pump that requires a compressed air to produce a spray. This pump can be used for different type of plaster finish like textured coating providing that they are not solvent-based materials. Lastly is the piston pump.
The piston pump is used for smooth finish with sufficient pressure without the need of compressed air. The challenge with this equipment is it has lower volume. The good thing with this is that compared with the first two pumps, a piston pump can be used for solvent-based materials.
