The Best Plastering Machine: Our Picks
Guide: Questions you should ask yourself before buying a plastering machine
With the help of a plastering machine, it is possible to cover large areas evenly with plaster and thus work quickly and efficiently.
The following section tells you everything you need to know before buying a plastering machine.
What is a plastering machine?
The moistened material is filled into a container located on the plastering machine. A valve connected to a compressor, for example, shoots the material out so that it sticks to the wall.
This makes it possible to cover relatively evenly large areas with building material quickly and efficiently. Plastering machines are therefore real time savers for extensive construction work and thus help to reduce costs.
For commercial use, there are professional machines that are able to work more efficiently and are designed for frequent use.
Here, it makes perfect sense for a construction company to make an investment in a plastering machine, as it quickly pays for itself through the time savings.
Compressor for the plastering machine
Usually, this requires a compressor that is able to compress the air and thus build up compressed air.
In principle, cleaning machines are usually sold without a compressor, since a compressor is usually already available, especially in the factory. Thus, there may already be a device that can be reused for another purpose.
Obi and Bauhaus, for example, offer the possibility of renting a compressor.
For private users, however, it makes little sense to buy an expensive compressor, as the price for this can easily run into several hundred euros. Some companies therefore offer the possibility of renting compressors for a certain period of time.
For the private user, this is often the cheaper way, unless the compressor is to be used for a longer period of time and/or for other purposes.
What are the alternatives to a plastering machine?
The disadvantage, however, is that the method with the spatula takes considerably more time than with a plastering machine. It is specially designed to cover large areas with a building substance such as mortar.
For smaller building jobs, you can use the spatula and do not necessarily need to buy another machine. For larger construction projects, however, we recommend using a plastering machine.
Decision: What types of plastering machines are there and which is the right one for you?
Besides the usual plastering machines that work with a compressor, there are also plastering machines that work with manual operation. This means that there are two different types of plastering machines:
- Hand-operated plastering machines
- Plastering machines with a compressor
In the following chapters, we will introduce you to the two variants so that you can find a plastering machine that is suitable for you.
What distinguishes a hand-operated plastering machine and what are the advantages and disadvantages?
As already mentioned above, there are hand-operated plastering machines. This means that a crank is attached to the container, which distributes the material on the surface when operated.
Similar to the other variant, it is thus possible to distribute the mass evenly on the surface. The big advantage, however, is that a compressor can be dispensed with.
So there is no need to rent or buy a compressor, the plastering machine is sufficient to do the job.
What distinguishes a plastering machine with a compressor and what are the advantages and disadvantages?
The most common type of plastering machine is the one with a compressor.
As described above, the compressor is connected to the plastering machine and the building material is ejected with the compressed air, which can be regulated via a valve.
It is therefore possible to spray the building material evenly over a large area. The compressor ensures that the work can be done quickly and efficiently.
Buying criteria: Use these factors to compare and evaluate plastering machines
In the following, we will show you which aspects you can use to decide on your ideal plastering machine.
The criteria you can use to compare plastering machines are as follows:
- Purpose of the plastering machine
- Material of the container
- Capacity of the tank
- Weight of the plastering machine
- Number of spray holes
In the following paragraphs, we will explain what is important in the individual criteria.
Purpose of the plastering machine
Before buying a plastering machine, it is important to know the purpose for which the manufacturer designed the plastering machine and which types of building materials can be applied with the plastering machine.
As already described above, all plastering machines work in a similar way, but the manufacturers can give you the certainty that the plastering machine is also suitable for your purpose.
Material of the tank
The choice of the material of the container is crucial if the building material cannot be removed on site. Normally, the container can be rinsed out so that no residues stick and contaminate the container in the long term.
Depending on the building material, cleaning can be easy to almost impossible.
However, if this is not possible, building material residues stick to the container and have to be scraped off laboriously. In principle, there are two different versions, one with a plastic container or with a metal or stainless steel container.
|Metal or stainless steel container||Robust||Heavier than a plastic container|
|Plastic container||More flexible than stainless steel||Will be damaged more quickly than a metal container|
The most common type of plastering machines are those with a stainless steel container. Stainless steel has the advantage that it is considered very robust and also has the property of not rusting. It is therefore ideal as a container for building materials.
The other variant is that of a plastic container. In contrast to the stainless steel container, this is less robust, but at the same time more flexible, so that semi-dry leftovers can be removed well and safely.
Capacity of the container
A sufficiently large container is needed so that the work can be done quickly, efficiently and, ideally, without constant interruptions.
This means that there are no stops between loading and applying, but that everything can be applied in as few passes as possible. This may or may not be the case, depending on your intended use.
It should also be borne in mind that the material in the container has an additional effect on the weight and is quite noticeable during longer work.
A good compromise should therefore be found between reloading the fettling machine and carrying comfort.
Weight of the fettling machine
Since you will probably want to hold the plastering machine securely in your hands for a longer period of time and spray the surface as evenly as possible, you should pay attention to the weight of the plastering machine.
The average weight of a plastering machine should be around 2.5 kg. In addition to the weight of the plastering machine, there is also the building material that is filled into the container. See the section "Capacity of the container".
Number of spray holes
In addition to the above criteria, you may also be interested in the number of spray holes. Roughly speaking, it tells you how evenly the mass can be distributed. The more spray holes there are, the more evenly the applied area will be.
The question here is whether you want to do precision work or cover a large area quickly.
Depending on the intended use, one or the other variant may be more suitable for you. A single spray hole, for example, is perfect for joints.
Some plastering machines even offer the option of closing the holes, for example by attaching screws to plug the holes.
This provides the necessary flexibility and ensures that the plastering machine can be used for several purposes.
Compatibility with the compressor
Since most plastering machines require a compressor, it is important to check the specifications. Does the compressor provide the required air pressure? Are the connections compatible or are special attachments needed?
The air pressure is specified in bar or pascal, for example. 1 bar corresponds to 100,000 pascals and a little less than 6 ATM (physical atmosphere). These values indicate how compressed the air in the container is. In the case of a plastering machine, approx. 5 to 6 bar should be sufficient.
To calculate the amount of air, multiply the air pressure by the volume of the container. For example, a 50 litre container at a pressure of 5 bar will have stored about 250 litres.
For example, if the machine has an air consumption of 50 litres/min, the machine could be used for 5 minutes.
However, the air pressure will decrease linearly, so most machines give a range of possible bars. To come back to our calculation, let's assume that the machine would need an air pressure between 4 bar to 6 bar according to the manufacturer.
That means we cannot drop below 200 litres of air in the tank (4 bar x 50 litres = 200). So the machine could effectively run for one minute with an air consumption of 50 litres/min.
Depending on the size of the compressor, you may have to make stops during the work to allow the pressure to build up again.
As a rule, however, this should play a minor role, as the compressor is often rented and the right model can simply be selected there.
In particular, most DIY stores offer a free consultation to convince you of what they have to offer. If in doubt, you should take advantage of this offer.
Facts worth knowing about the topic of plastering machines
How does a plastering machine work?
As already described above, a plastering machine is a relatively simple device. A container is installed on a rod that holds the building material ready for spraying.
The air pressure is directed through the rod and can be regulated with a lever. The air pressure presses the material outwards and a spraying effect occurs.
All that remains is to point the plastering machine at the area to be applied and press the lever. The building material is applied almost automatically.
The rental offer of compressors for plastering machines
Only very few private users are likely to own a compressor that is suitable for a plastering machine.
Some companies therefore offer the hire or rental of such machines. Common DIY store chains, such as Obi or Bauhaus, also offer such services.
You can expect to pay about 30 euros here if you rent it for a day. Some DIY chains also offer a weekend rate, which is even cheaper than several individual days together.
If a DIY store is not an option for you, you can also search Google to find other local providers who offer such a service. In any case, we recommend that you check out different offers to find the best deal for you.
The most important parameters for assessing compressors include: The compressor power, the air pressure built up, the size of the unit and the type of connection. The following section gives you a rough overview of these parameters:
- Compressor capacity: For example, the value 150l/min means that a volume of 150 litres can be dispensed within one minute.
- Air pressure: Roughly speaking, the air pressure indicates how compressed the air is or how close the air molecules are to each other.
- Size of the unit: If you rent or borrow the compressor, you will usually have to transport it.
- Type of connection: Since the compressor is connected to the plastering machine, the connections of the hose and the compressor must match.
Please note that other factors also play a role, such as whether the compressor is oil-free or lubricated. We therefore strongly recommend that you consult a suitable guide before buying.
