Questions, comments and opinions

The flow rate seems low. It's strange. There are compressors with a 50-liter tank that have an intake flow rate of 270l/min. This one has 187l/min.?

So, for a compressor to work without issues in a hobby setting (meaning if you are plastering your own house at a relaxed pace), you need a minimum intake flow rate of 250 l/min, a pressure of 8-9 bar (never exceed 9 bar), and an air tank of at least 50 liters.
Ideally, it should have 2 pistons instead of just one. For 2-piston engines, the flow rate is double (400l/min) and the engine manages to fill the tank much faster and sometimes take a break.

If you work in a professional setting, meaning with a team (one at the concrete mixer, another loading, another using the straight edge), you need a compressor with a 100-liter tank, the rest of the parameters remain the same (flow rate, pressure, etc.).

If you already have a smaller compressor and do not wish to invest in a more powerful one, you can use the Tenka machine with only 2 nozzles. You block the rest of the nozzles; some blocking caps are included in the package. With 2 nozzles, the machine loads up to 2 cm of plaster thickness in a single second if you hold it in position. So it is quite fast even with 2 nozzles. The excess pressure will be released from under the gun trigger.

I plastered the exterior myself with TENKA in 3 days, less than 20 hours of work combined; I was the one applying the plaster (it requires some forearm strength), 1 person leveling with the straight edge, and 2 people at the concrete mixer and carrying. This was on the second day when we worked full time from morning until afternoon; on the first and third days, we worked in 3 people for about 4-5 hours each. You have to move fast because the plastering goes quickly; you can't get the job done with lazy or incompetent people. The sand must be okay, with no other impurities in the material, soil, stones, or hardened concrete, because you'll waste more time unclogging the pump than plastering. The pump must be disassembled and cleaned at every meal break because material gets inside, and if it hardens, it's much harder to clean.

I will look into it and let you know as soon as I have an answer.

They are currently in testing. I cannot give you an exact date.

Yes. It's on the list. (Olari village, Olari commune ) a colleague will call you.

If all the nozzles are running, what compressor is needed? Thank you.

It works with 3 nozzles but with short breaks. If you work with 2 nozzles, it runs continuously without problems. You can find an example with a similar compressor at another client here

I'm passing this on to my colleagues. It will be resolved immediately.

You must have the warranty certificate, invoice, and instructions. If anything is missing, let me know and we will send it via email immediately.
In case of a malfunction, my colleagues will find you in the database without asking for any document, invoice, or certificate. If the extended warranty is written on the invoice, that is enough. The clauses are identical to those in the warranty certificate, except that the validity is extended through the invoice.

The warranty was not included in the package. I received the pump and a set of spare consumables and accessories. But it seems the extra warranty was not included. I will post a photo of the invoice. If you can, please send the warranty to the email address cocoirimie@yahoo.com thank you

Thank you. It's been resolved. I received the warranty by email.!

Do you ship to the Republic of Moldova?

Now shipping throughout Europe.

It comes with a high-flow gun, a universal "male" quick coupler, and overpressure protection. (for example, if you work with a single nozzle, the excess pressure will be released from under the gun's trigger ... it has a valve there) the one on the site is an older model. It is no longer in stock.

Thank you for the reply... I just placed the order.. I'll keep you updated .. maybe I'll also make a video after the compressor arrives as well .!!

It works very well. You have customer videos on the website.

Sure. Call me 0723323910

We already have the spray gun from you. However, we would like to somehow enlarge its hopper because perlite plaster is very light and gets used up extremely quickly. Can a hopper be made with different dimensions?

You should have placed the order as well, not just left it in the cart. That's what happened to me too.

1. Lockable nozzles (caps included in the package)
2. 3-year warranty + fast service (from one day to the next)
3. Can be used for spatter coats, can work with MP plaster (with a single nozzle)
4. Ceilings can be plastered easily due to the upward-angled nozzles.
5.The nozzle threads are metallic and not plastic.
6.The hopper support handle is cast (solid). In 5 years, not a single broken handle has ever returned for warranty or service.

Tip: wherever you want to buy a plastering machine from (China, Italy, Romania), keep 3 essential things in mind.

1.It should have lockable nozzles so you can work with a maximum of 3 nozzles and be able to apply the spatter coat (spritz) with one nozzle. With 4 nozzles, you need a serious compressor. Note: spatter coat does not mean cement milk or that watery mixture applied with a trowel on the wall. Spatter coat means mortar sprayed like a grain of rice (it should scratch if you touch it with your palm). This creates maximum adhesion with the thick plaster. And a bonus secret: the spatter coat should not be allowed to dry completely, but partially. Load the plaster over the spatter coat while it is still semi-wet so that the contact bond is both mechanical and chemical.

2. The handle that holds the weight of the mortar hopper should be vertical (meaning upright and not horizontal). If it is horizontal, all the effort is discharged into the shoulders, neck, and back. If it is vertical, it only strains the biceps (arm muscle) and the neck is relaxed. After a day of plastering, this detail matters. Take a dumbbell or a bottle of wine and lift it with your fist horizontal and then vertical. You will perfectly understand what I am saying.

3. Warranty, service, and consultancy should be fast. For example, we resolve service issues via courier in 24-48 hours because we know what it means to block work on the construction site. If a nozzle gets clogged on the site, for example, you don't sit around filling out emails and online forms, but you call the phone number written on the machine and in 3 minutes a colleague explains how to unclog it. It's a minor detail, but believe me, it matters in practice.

The model with 5 universally lockable nozzles (walls + ceilings) is the newest and most updated in stock. You can use 1, 2, or 3 nozzles for walls or 1, 2 nozzles for the ceiling. The minimum compressor tested for this device must have at least 50 liters (tank), 8-9 bar, 270 l/min. intake flow. Look for the 2-piston model because it has a flow rate of 400 l/min. The nozzles are optimized, the gun has an increased flow rate and overpressure protection.
The ones with 3 nozzles will be discontinued soon.

Hi, what model do you have?

The one with 5 nozzles. Which is currently on sale on the front page.

Thank you for the feedback

What compressor are you using with it?

I have replied to Ms. Ruxandra below. Sincerely,

Works without any problems. Example here
. To avoid overloading the compressor, you can work with 2 nozzles. Caps are included.

You need 360 liters of air per minute to be able to use it, and if the air pressure is low, it will not spray on the wall.

works well with 270 l/min.

Works flawlessly.

Male quick coupler or hose tail with clamp. At the customer's choice.

With this model, (the one with 5 nozzles) and a compressor of at least 50 liters, you can work continuously. You can find videos from our customers on the website. Example here

Coming soon.. it's in testing.

It works very well with a 50-liter compressor. It has enough pressure to fill gaps of 5-7 cm in the first layer. See videos from our customers on the site. Here are a few videos here:

We recommend working with classic/manual/traditional material: cement + sand, but the machine works quite well with MP75 as well. We have posted many videos from our customers across the country on the website. Example: here

It works, but using machine-applied plaster is not recommended. It's sticky and you'll struggle with it. A lot of it falls on the floor. mp75 is for hose transport and not for traditional plastering. You have videos on the site from our customers who have tested mp75. Example: here

answer below. regards

Yes, but only with a single nozzle (blocking caps are included in the package) and it must be smoothed with a trowel afterwards without fail .. advice: Generally, the plaster is applied very easily directly with a trowel. Don't complicate things with compressors and plastering machines if you only have plastering to do.

I have replied to Ms. Ruxandra below. Sincerely,

Yes, the device can be successfully used by beginners. We have many women who have plastered their walls themselves. See the section: -videos from our customers-

There are hundreds of plaster recipes (with clay, with gypsum, with cement, etc.). The simplest test to see if the device works well with your desired plaster is the following:

Take the respective mortar with a trowel and turn the trowel 90 degrees. All the mortar must fall off the trowel. If it stays stuck to the trowel, it means that the plastering machine won't be able to throw it completely onto the wall either, and there will be waste.

This problem usually occurs with machine-applied plasters that contain additives and plasticizers to make them more pasty so they flow through the hose more easily. That's why they are also stickier. But if your plaster passes the trowel test, the plastering machine should also throw it perfectly.
You can find the test I'm telling you about in this video at minute 1.55.

It works with any type of plaster (both classic and mechanized), but it works best with classic plaster: multibat + sand (note: coarse sand, not fine) or with plaster made from scratch according to the sand+cement+lime recipe. You have here a video with this mortar example.

As the most affordable price option that also does a good job, I recommend: the Einhell model (German) 2 pistons, 50-liter tank, 10 bar, 400 liters suction capacity, 270 liters delivery rate, low consumption, quiet. example here

It depends on how many nozzles you use.
Since many customers ask about this, I asked my colleagues from the technical department for a clear table with the compressor tests. The table can be found here

Thank you! Could you also recommend a type of hose? I would need one of about 10 m; should it have a specific diameter?

8mm internal diameter. You can use a simple gas hose. It costs about 3 lei per linear meter and withstands 25 bar. Get at least 15 m to stay at a distance from the compressor. After a day of work, the compressor noise can be stressful.

Sorry for the delay. I saw that you have already ordered. The 5-nozzle model fully includes the 3-nozzle one, but it has 2 additional nozzles pointed towards the ceiling to make the work easier. All nozzles can be blocked (you have the blocking caps included in the package). The warranty is the same for both models: 3 years.

We will soon make a video with resistance tests through which we will demonstrate how tough that plastic is.

What compressor do you use?

What brand is the machine? Thank you.

There are different prices. It was a promotional price. There will be a promotion again in a few days. Both are very good.
The model with 5 lockable nozzles includes the 3-nozzle one in its design, as it is built on the same chassis, but the pneumatic manifold has been updated with 2 more nozzles angled towards the ceiling. It is very possible that the 3-nozzle one will be discontinued for this reason. The 5-nozzle one is practically universal. All nozzles can be locked/unscrewed/cleaned. (you have instructions with images)
The warranty is 3 years for both models, so the choice is purely subjective.

You're right. I wasn't paying attention to the price.

Is cement or gypsum plaster better? Thank you.

It works with both types, but we recommend cement plaster. More durable, more porous, the wall breathes easier through it, moisture resistant, and... of course... cheaper. Cement vs gypsum forum

The spray gun with 3 lockable nozzles: link pistol

The most commonly used and cost-effective mortar: link mortar

Cheap compressor (hobby) but tested by us on the 3-nozzle model: link compressor
Use sand with a grain size as large as possible: 0.3 - 0.4 mm
Other mortar recipes can be found in the instructions in the package. Good luck with your work and God bless.

The models with 5 nozzles also have 3 nozzles for the wall and 2 for the ceiling. But not 4 ...

We'll put it under warranty. Call me at 0723.323.910

Imagine filling a jar with walnuts and then adding rice. The rice will fill the gaps between the walnuts. It's the same with mortar. The cement completes the sand mass. If you use sand as fine as cement, it will result in a sticky "paste" that you won't even be able to work with a trowel. Follow the instructions on the Multibat bag (washed sand 0.3 - 0.5).

needs coarse sand

Only compressed air passes through the nozzles. The air, in turn, pushes the material through other much larger orifices (approx. 2cm diameter). Work with sand as coarse as possible (0.3 - 0.5). The nozzles do not wear out, but they can be lost as they are very small, or the thread can be damaged if they are over-tightened.

It works, but work at a relaxed pace with breaks every 5-6 cups. It is best to cover 2 nozzles and work with just one. The 24 l compressor is below the requirements of the plastering machine.

It doesn't work. It's weak with 2 nozzles. It works well with one nozzle.

If 55 square meters can be done in an hour. Each square meter has an average thickness of 2 cm. It results that in one hour 55 x 0.02 = 1,1 cubic meters of plaster can be done. (Approx. 8 concrete mixers). Generally, yield is calculated as covered surface area and not as mortar consumption.
