We propose to consider professional tools and devices that are still rare in the post-Soviet space, which make it possible to simplify painting work. In this article, we’ll talk about putty machines, mechanical application systems, and construction stilts..
Painting work is one of the most time consuming and “dirty” jobs. Unfortunately, they do not lend themselves well to mechanization, and it is not always possible for helpers to be allowed into even the most, at first glance, simple operations. The skill of a specialist here is determined by persistent motor skills. But foreign colleagues still managed to optimize the surface finish. For this, special tools and devices were developed, the price of which “bites”, however, they pay off with interest if you do painting work professionally.
We will talk about stations for applying putties, but note that many of these machines are quite versatile and capable of interacting with several types of building compounds. They can:
- apply waterproofing and fire retardants;
- pour thin screeds and floor leveling materials, etc..

In this case, the “additional abilities” of the station in different models are presented in their own way. There are no devices that do everything equally well.
The main task of the spraying equipment, which is positioned by the manufacturer as a filler, is to help the painter with viscous and heavy mixtures.
The filling machines are based on airless spray technology. There is no usual compressor here, and the mixtures are pumped using a pump. The material is fed to the gun under high pressure, and spraying is carried out due to a sharp drop in pressure in the nozzle area. Airless technology allows working with heavy and coarse-grained mixtures (grain with a diameter of up to 4-5 mm) with a high degree of transfer (low material loss).
Note that the pump drive can be of several types:
- gasoline (ICE)
Electric puttying machines are the lightest and most compact, they are most often used in civil engineering.
What are the advantages of such units for painters? Let’s name only the key.
- The productivity of painting work is increased by about three times (profitability in plastering operations, on facades, etc. – even more).
- No helpers needed.
- With standard ceiling heights (the rods allow reaching up to 3 meters or more from the floor), work can be performed without the use of scaffolds and scaffolding.
- There is no significant overspending of putties from the fall of the mass on the floor, as in manual application.
- Personnel fatigue is reduced significantly.
- The quality of work increases.

When choosing an apparatus for puttying, you need to figure out in advance: what materials will be the main ones, on which objects the machines will be used, whether you plan to develop. To give preference to a specific model, you have to understand the technical and operational characteristics.
Do not pay attention to the pressure and speed of movement of some nodes. Here the main indicator is liters per minute, it just determines the capabilities of the station and relates it to a specific class. Apparatuses for 3-4 l / min are considered average for one operator. There are powerful stations that allow you to connect several pistols at once. Sometimes the device is designed for one pistol with a large nozzle, but it makes it possible to connect two if the nozzles are of a smaller diameter.
The change in performance can be carried out in several steps or in a smooth way. Obviously, the larger the range of adjustments, and the more accurate they are, the more versatile the machine will be..
Some models with their electronics control pressure parameters and automatically control the motor. For manufacturers, the rule of good form is the use of a display, which displays all useful information (pressure, flow rate, performance).
The operating voltage of a plastering machine usually depends on the power of the motor. Naturally, the best-selling units are 220 V units, which can be powered from a regular household outlet. More powerful stations are connected to three phases. But there are also universal plastering machines “220/380”.
More power always means more flexibility. For example, to work at a sufficient distance from the station or with more viscous mixtures. The average figure can be considered 1.5-2 kW.
The range is important on large objects and especially on facades. Here it is not always possible to focus on the length of the high pressure hoses that come with the kit. The main thing is passport data. Please note that the working distance in height is always an order of magnitude less than horizontally.
The material with which the putty station works
Some materials for a particular machine are suitable immediately, while others need to be upgraded: use larger hoses, connect a compressor, change the gun. It is very important what fraction of the grain can be sprayed by the installation, what formulations by the type of binding agent are applicable. Some putty machines only work with ready-made putties, produced in buckets or in plastic bags. And other systems have a hopper, after connecting to the water supply, they themselves knead dry building mixtures and continuously supply the finished mass.

TapeTech mechanical puttying tools
TapeTech has become an innovator in its business and an undisputed leader. The puttying tools of this brand are integrated into a system and complement each other. They are intended for the mechanization of painting work, primarily focused on finishing surfaces sheathed with plasterboard or gypsum fiber.
These devices do not allow to completely exclude some operations, as a rule, when puttingtying, you will need to apply all the same 3 layers, and dry each one. But time and effort can be saved, therefore, you can earn more. Some work is so simplified that it can be entrusted to an assistant. It is important that all tools either have a longitudinal configuration or lengthen, therefore it is possible to work without a scaffold in rooms with a ceiling height of up to 3 meters.
“Bazooka” is a hit of the company. It is a device in the form of a rather thick aluminum tube (hence the name). It is intended for filling joints of sheet sheathing. The main feature of this tool is that in one pass along the working area, a filler substrate is simultaneously applied, and the paper connecting tape is rolled / pressed / cut. Interestingly, the device can be used for sealing not only vertical wall joints, but also for horizontal work and on the ceiling. And you can also reinforce corners with “Bazooka”.
To finish the planes, the designers have come up with nozzle boxes that allow you to apply a thin-layer strip of putty in one motion. The design of the device is quite simple: a ready-made or previously prepared putty is loaded into the box, when it passes through the slot, it is applied to the base and immediately picked up with a spatula blade. Material feeding is carried out due to the fact that the operator presses on the rollers during the passage. Depending on the purpose, the width of the box is selected: to cover the tape in the seams, use a nozzle with a width of 175 mm, for the next leveling and finishing layers, take boxes of 250-300 mm.
Sealing of self-tapping screws recessed on the plane of drywall is done with another nozzle. If each groove is usually coated, then here a box-shaped nozzle 50 or 75 mm wide is carried out along the entire line of fasteners, the putty remains only on the caps.
To roll the tape at the inner corners, the developers suggest using a special roller. This nozzle will press the paper into the putty during wiring and form an even cut of the corner.
A corner finisher is used to simultaneously remove excess weight and apply a second layer. It is installed on the articulated handle and after the roller is guided along the inner corner. Outside corners for finishing are processed with ordinary spatulas or box nozzles. Finishing the corners is done with an applicator in tandem with a finisher. They can work together with the MadRunner device, which contains a certain amount of putty and a gas spring feeds it into the nozzle..
A TapeTech mechanical filler system would be incomplete without a filler pump, nozzle holder handles (860 to 2500 mm), and an assortment of adapters and adapters. A metal case is offered as a separate item.
Note that there are other manufacturers of similar tools. In view of the exoticism, the estimated cost of technically complex “bazookas” in Russia can reach up to 100,000 rubles (abroad they cost about 1000-1200 USD), other accessories, of course, are much cheaper.
These devices have long been used in the West. With their help, builders manage to minimize work on scaffolds and stepladders. They have proven themselves especially well if you need to move a lot, for example, when wrapping sheets of gypsum board on the ceiling, when laying communications, when puttingtying high walls and ceilings. The work of a painter generally involves a constant change of workplace so that the layers can dry out..
These products are truly high-tech. Only high-quality materials are used here (mainly: aluminum, magnesium and steel), the design is thought out to the smallest detail. There are always convenient anchorages for the lower leg, the supporting frame is supplemented with springs or pneumatics for stability, the height is adjustable at intervals of 50 mm, the foot plate is adjusted to different sizes, fixation is carried out with straps or Velcro. The support heel is rubberized, it can be movable and also with springs. It can be of a complex shape, voluminous or even divided into two parts (it is believed that this increases stability).
There are 3 main standard sizes of stilts for the average builder, they differ in height:
- 38-60 cm
- 46-76 cm
- 61-102 cm
As you can see, there is a decent margin for height adjustment so that the working area is always at arm’s length. Each of these sizes is recommended to be selected for rooms with a ceiling height of 2.6 to 3.2 meters..
Another point that is important when choosing is the permissible weight of the user. It is clear that you cannot overload the devices.
To make working with stilts convenient, it is recommended to have a table at the facility where the tool will be laid out, and ready-made mixtures will be located. This is not so important if you use different holders for painting nozzles – reaching the container on the floor is not a problem. Interestingly, some countries require that a team working on stilts have at least one person “on foot”.
Finisher stilts of the “quality China” type (up to 60 cm) cost about 6,000-7,000 rubles a couple. But for similar samples from Europe or the USA, they ask us up to 20,000 rubles.
Mechanization of painting work is gradually taking place on domestic construction sites. Due to the still high prices, professional tools, stations and accessories are purchased only by large firms. On large volumes, they significantly increase the profitability of finishing work and easily replenish their expenses. It is only a matter of time before these innovations become cheaper and appear in ordinary “teams”.
