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.
The benefits of using a plaster sprayer are multiple. In this article we look at what one is and why you might want to use one.
The main benefits of using this type of machine is speed. Using a plaster sprayer enables a plasterer to skim a wall up to 5 times faster than using a hand float would. The type of plaster that is preferred by users is the pre-mixed organic-based plaster that is available in a plastic bag. Some of our machines are designed with a built-in mixer to which you can add your own materials.
The benefit of using pre-mixed plaster is that it is not necessary to clean out the machine after the completion of the job, just as long as the plaster is kept moist. Using this type of plaster also allows for any surplus to be used, therefore preventing waste. It also means that it’s not necessary for the plasterer to mix the plaster and haul the necessary water to do so. It’s also possible for the plaster sprayer to use gypsum-based plaster just as long as it’s the ‘spray grade’ version.
A major benefits of using the plaster sprayer is speed. For example, quite often the plaster can dry rapidly enough for the wall to be painted within 24 hours of application. Of course, the success of this will depend upon the level of humidity and the ambient temperature.
There are 4 main types of plaster sprayer namely:
Pneumatic sprayer – this is the most common type of machine and it has a hopper to hold the plaster that is connected to an air compressor. They are low cost and very basic.
Worm-drive pump – a pump sends the plaster into a large-nozzled spray gun. Compressed air then blasts the plaster to spray the wall.
Peristaltic pump – this type of plaster sprayer uses a peristaltic pump which works by adding the plaster to a tube that is then squeezed by rollers. It also uses compressed air to create the spray.
Piston pump – the most modern and advanced type of plaster sprayer uses a piston pump to spray smooth plaster without the use of compressed air.
Some plaster sprayer machines are designed with an internal mixer. They use advanced technology to not only mix the plaster powder and water together for you but to ensure that it’s of consistent consistency and will therefore eliminate the fluctuations of thick-thin that no professional plasterer wants to contend with. They are also built to be easily cleaned so that the components such as the pump and the mixing shaft stay in good working order for far a longer lifespan.
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.
In our game, time is money, after all and the plaster sprayer provides a major speed advantage to the professional. This speed and the ease of plaster application is outstanding with these modern machines. They are able to ‘cut in’ around any features such as timbers and also the ceiling line.
Plasterers are usually pleasantly surprised that hauling plaster up to the top of scaffolding is no longer necessary with the right machine. Jobs that used to take up to 15 crew members working by hand, can now be performed by just 5 people or so.
