Features of machine plaster wall

In this article we'll discuss one of the most modern methods of applying the finishing layer - machine plastering walls.

It is produced with the help of special equipment - plants for machine plastering.

In comparison with the cost of manual labor plasterer, finishing by machine greatly reduces the cost of the cost of the building decoration.

Machine plaster

on the market are reliable devices for machine method - PFT, Putzmeister and Kaleta.Depending on the manufacturer and a set of machine functions by weight can be 100 kg to 280 kg.

most heavy machinery, in addition to the finishing plaster, designed to create a self-leveling floors, masonry mortar, adhesive plaster.

feeding distance ranges from 10 to 50 meters.Performance

unit depending on the type of pump and a mixture of 2 to 20 liters (60 gallons per professional multifunction machines).

hopper lets you fall asleep at one time from 30 to 75 kg of material.If you want your car to finish building the walls, you'll notice that it runs with the right types of mixes you.

In case requires a broad range of applications, pay attention to the multi-function device with a higher price.

apparatus consists of the hopper for filling the dry mixture of the compressor which feeds the compressed air through, a mixer for mixing with the water hose and the working gun.

Selection of the dry mixture depends on whether it is external or internal plastering work.For facade suitable mixture on a cement-sandy basis.

For interior walls in rooms where there is no moisture, apply a plaster base.

In both cases, the manufacturer added curatives and additives, which are responsible for the uniformity of the dried stucco and provide cracks.

Choosing mixture, make sure that it is suitable for application by machine.

Temperature, allowing work on machine plastering, +10 degrees.Not allowed in the room drafts and strong winds for the exterior.

The higher the humidity, the greater the time required for complete drying.

Before you start plastering machine-read instructional videos.Note how the composition is applied.

The video shows that the worker puts the solution from the corner plastering range is chosen such that there was no need to move with the included gun.

Further work with plastered surfaces are manufactured similarly to the processing technology for manual wall plaster - leveling and smoothing.

Before the first start-up read the instructions to the machine, take a few test application, changing the speed and power supply solution, pay attention to the time required to mix before serving, and the time during which the solution can be stored in the tank when the machine is operating.

Procedure

When machine plastering should adhere to the following procedure.

Prepare the device is as follows - the device connects to the network and the water supply.

If you do not have access to central water supply, the pump can be connected to any water containers.In the process of the plaster is important to monitor the availability of water in the tank.

undesirable to use process water not suitable for drinking from wells - the presence of salts in a significant amount in water can react with the additives contained in the mixture that will weaken the plastic mixture for the walls or other negative effects.

Surface preparation is done in a standard way - the remnants are removed construction debris, cleans nodules.

When should render over different mating surfaces of the walls (for example, a wall of bricks joined with the wall of drywall), the connection points are reinforced with a fine mesh construction unit 1x1 cm.

This will prevent cracking plaster at the junction of dissimilar materials.If the walls are exposed metal elements, they must be treated anticorrosive composition.

After that, with surfaces blown off construction dust, this is especially important if you will be pre-primed.

If the instructions to mix plaster otherwise stated, the walls of cinder blocks, concrete blocks, brick or any other building material having abrasive surface fit, you must be primed and allow the primer to dry completely.Now the wall is ready.Application

working solution to the surface of the walls is made from a distance of 20-30 cm from the surface.

Work gun should hold so that solution flow occurred exactly perpendicular.Before the plaster is applied to the main surface, fill all corners and joints.

layer thickness is regulated by the speed of movement of the gun along the surface.The mixture is applied downward such that the upper layer covers the bottom of the solution.

When the plaster is applied to one lane, you can proceed to the next, thus necessarily do all overlap.

Cropping surplus made after the plaster is completely frozen, with a tool called a rule.It

or trowel applied firmly to the surface and pressure is held down.To see whether the plaster hardened enough, you can in the following way - attach the tool to the wall and try to trim the solution.

If the rule does not extend beyond the viscous mass and after cropping is an even layer, then the plaster is ready for cropping.Permissible deviation from a perfectly flat surface 1-2 mm 1.5-2 meter length of the wall.

Plastering of walls by machine will be flat after 30-40 minutes after the plastering strip, moisten the wall of a small amount of water and will generate grout.

advantages of machine plaster

Machine plaster has several advantages compared with manual, namely:

• Speed ​​plastering.When the plaster is carried out manually, the solution is prepared in small amounts, it is spent on mixing time.The station mixes solutions automatically.Speed ​​plaster walls with the station 4-5 times greater than using manual labor;
• saving materials.The average cost of dry mix when applied manually is 16 kg / m².The estimated production of 1 sq.m.method for machine - 13 kg / sq m.When plastering, such as a private home, in hardware, you can achieve savings of 300 kg of plaster and more;
• High quality adhesion to the wall is ensured by applying a mixture of a high pressure, which can not be achieved with manual method;
• Minimizing labor costs.The laborious and time-consuming mixing process is carried out automatically.Also there is no manual transfer of the prepared solution to the wall where the plaster is made.

As we discussed in the article and in the video, the quality and speed of work on plastering the walls by machine is much higher than the manual method.

station pays off during a significant amount of work (depending on the station - from 700 to 1200 m).

station acquisition also warranted if you are planning to lease it or provide services finishing machine.

In much smaller quantities or one-time work on your site, you can buy a used station, or take it for rent.
