Hopper bucket for applying plaster with a compressor

Plastering large wall areas effectively can be greatly enhanced by utilizing a hopper bucket with a compressor. This is an incredible tool for both professional plasterers and do-it-yourselfers. Plaster can be applied swiftly and evenly with the hopper bucket, which saves time and effort over more labor-intensive techniques.

The ease of use and efficiency of a hopper bucket are what make it so beautiful. Plaster is sprayed onto walls using compressed air in a bucket that is connected to a compressor, providing a uniform and smooth finish. This technique guarantees a more even application across the surface while also expediting the process.

Understanding how to use a hopper bucket effectively can greatly enhance your plastering results, regardless of whether you’re working on a large-scale construction project or a home renovation. It is a useful tool that improves the efficiency and caliber of your work, so it is a must-have for your plastering toolbox.

What is it

A plastering tool called a hopper bucket (also known as a plastering shovel) uses air pressure to spray plaster onto walls. For automated application of gypsum mortar or cement-sand when leveling walls, as well as for decorative finishing with acrylic plasters or "liquid wallpaper," a pneumatic bucket is utilized.

A pneumatic bucket functions similarly to a cartridge gun in theory, but it is different in terms of design, productivity, and the quantity and size of its nozzles.

The diagram displays the bucket’s device:

The basic idea is to either scoop the plaster mortar out of the container or apply it to the bucket (hopper). A handle is attached to a compressor hose. When the trigger is pulled, compressed air enters the hopper, travels through it, and shoots out through the plaster and nozzles, spraying the mixture onto the wall.

Advantages:

• High speed of finishing works. One person can plaster about 60 m2 per hour, which is 3-4 times faster than manual application of plaster.
• Suitable for any mixtures (cement-sand, gypsum, clay, lime, glass fiber-
  concrete, waterproofing, liquid wallpaper, etc.). Permissible particle size in the solution is up to 10 mm.
• Due to the high impact force of the solution on the surface, the adhesion of the applied material and the strength of the coating increase.

Drawbacks:

• The weight of the equipment with a metal bucket filled with plaster is about 10 kg.
• Splashes from the sprayed solution fall on the floor and clothes. Manual plastering is “cleaner”.

Plastering walls is a labor-intensive and time-consuming task that is revolutionized by using a hopper bucket with a compressor. It becomes a fluid and efficient process. With the speed and uniformity of this tool, plaster is sprayed on large areas in a fraction of the time it would take by hand. It allows you to achieve a professional finish with less effort, which is a game-changer for both professional plasterers and do-it-yourselfers. This technique improves the quality and efficiency of your plastering work by making the application of plaster less intimidating and more precise, whether you’re working on a small home project or a larger construction site.

Types of plastering shovels

Two kinds of pneumatic buckets exist, depending on the use:

• Wall. Designed for plastering walls and corners (looks like as in the photo above). Sometimes it has an additional handle on the bunker for convenience.
• Ceiling. Designed for applying plaster to the ceiling and near-ceiling areas. Specifically for this purpose, the angle of the hopper relative to the handle, as well as the nozzles in the hopper, has been changed. The extended handle allows you to raise the hopper bucket higher without using ladders and supports. All this allows you to comfortably work in a vertical position, without fear of the mixture falling out of the hopper.

Connection kit

Now let’s see what more is required in order to connect and use the plaster shovel.

An internal threaded geka adapter is fastened to the tool’s handle. The hose is filled with another coupling that has a nipple and clamped shut. It is very easy to connect two couplings; all you need to do is combine them and turn them half a turn. The other end of the hose is similarly attached to the compressor.

Select a rubber hose with an internal diameter between 16 and 18 mm. Up to 350 liters per minute of air supply cannot be provided by a smaller section. In order to withstand the pressure of the supplied air and maintain its mobility in the cold (without stiffening), the hose needs to be reinforced with threads. Observe the marking and select "VG" for water/gas.

Compressor air Selection must be made in accordance with the bucket’s hopper specifications, such as the necessary air supply (l/min) and pressure (atm). In turn, the quantity and dimensions of the feed holes affect air consumption. For instance, a hopper bucket with four 20 mm nozzles can be used with a compressor that has a 350 l/min capacity and an 8 bar operating pressure.

Additionally, be mindful of the receiver’s volume at the compressor. For continuous operation, the receiver (compressed air storage tank) guarantees a constant air supply and outlet pressure. The compressor is turned on less frequently the higher the volume.

How to do it yourself: drawings and dimensions

Because the hopper bucket operates on a fairly simple principle, artisans create their own pneumatic plastering tools. When making a pneumatic bucket for an existing small compressor or for a one-time small amount of work, this makes sense.

The blow-off pneumatic gun and small parts will cost money, but you can make the tank with materials you already have at home, such as plastic canisters, tin, or stainless steel.

Let’s look at a few possibilities for a do-it-yourself plaster shovel.

From tin

1. Making a tank. On a sheet of cardboard, draw out the dimensions, then transfer the scan to a metal sheet and cut out. The edges can be fastened with welding, rivets or bolts. Holes with a diameter of 18 mm are drilled under the nozzle with a crown.

For your article on applying plaster with a hopper bucket and compressor, the following conclusion is suggested:

Plastering is much simpler and goes more quickly when done with a hopper bucket and compressor, especially on larger surfaces. This tool helps both novices and seasoned pros achieve a smooth finish by providing consistent and even results. Process automation lowers effort requirements and enables more productive work.

A hopper bucket can help achieve quality plastering with less hassle if used properly and with some practice. Whether you’re remodeling or starting a new project, this technique is a terrific way to save time and make your walls look better. Knowing how to operate this equipment properly will make a big difference in your plastering abilities.

Your projects will perform better as you get more accustomed to using the hopper bucket and compressor. This technique is a great addition to any plasterer’s toolbox because it makes wall and ceiling transformations swift and elegant. Thus, why not give it a shot on your upcoming project and see the results for yourself?
