Time monotonous wall design in the wall paper gone. Was replaced by the period when the surface finish has turned into a creative process that allows the same material to create a unique design of a room or building facade. A platform for the manifestation of aesthetic taste and artistic talent is decorative plaster. Different techniques of its application contribute to the formation of the individual interior. That includes a preparatory stage and what are the ways to design the walls and ceilings of decorative plaster there, consider the details. The proposed video will help to deepen the knowledge on the studied theme.

The variety of material ↑

Before describing methods of applying a finishing material, you must make a brief digression on the diversity of its species. There are several parameters on which conduct classification the plaster. Depending on the binder, plaster is:

Acrylic. Presented in the form of a mixture having the consistency of paste. This decorative plaster is extremely convenient for a variety of technologies for the structuring of the surface.
Mineral. As a basic component, acts as a cement. Cheap mixture is optimally suited for outdoor use and in rooms with high humidity. Powder before applying diluted with water in the specified proportions. From the point of view of environmental safety is the most harmless product.
Silicone plaster is based on synthetic resins. Its numerous advantages provide a wide range of applications in terms of the harmful effects of the ambient climate.
Silicate based product, liquid glass. The most reliable material for decorative finishing. Maximum durability and resistance to the negative factors are the reason for the high cost of the product.

The composition of the plaster affect its final appearance. On this basis, decorative plaster can be divided into the following types:

structural;
silk;
Venetian, etc..

Depending on what application technique of decorative plaster selected, the material is able to simulate a variety of surfaces ranging from stone or wood, ending with the Wallpaper. The presence of artistic skills allows you to create exclusive wall panels.

Preparatory activities ↑

Preparation of walls before applying the decorative finish is a prerequisite for producing high-quality coverage, regardless of the chosen technology. The process includes the steps are the same for all types of plaster and nuances that depend on the composition of the material. All the preparatory procedure that precedes the application of a decorative layer, includes the following steps:

Removing the old coating, the presence of detached layers of old plaster is eliminated.
All grease and oil stains are displayed with special tools.
Cracked, chipped carefully closed, protruding surface stray. To eliminate significant damage will need grout, minor flaws are handled putty.
After removing the dust and dirt we recommend applying a primer composition.

The Council! In conditions of high humidity it is better to use antiseptic to prevent mold.

Technology for executing surface decorative finishing material includes the preliminary application of a thin layer of plaster. Aim for a perfect surface is not necessary, in the future, all tiny flaws will be masked. After drying, following the rules of application technique, it is recommended to reprocess the wall of the primer composition of deep penetration. These measures greatly increase the adhesion of adjacent layers. The nuances of surface preparation and simple techniques of applying a finishing material is described in the following video:

Options for the design of structural surfaces plaster ↑

Designed for application of decorative finishing structural plaster opens up a wide scope for the manifestation of creative abilities even with minimal skills. There are many techniques of applying this material, which can be divided into several groups:

with the use of textured rollers or stencils;
the method of spraying;
the use of various scrap materials.

After reviewing several application techniques to choose the most suitable method will be easier.

Work with cushion ↑

From the material at hand should be directly decorative plaster as finishing coat applied wax based color and color. Basic tools – a spatula and a roller (textured or pile).

Technology of application of decorative plaster with the use of a roller having pile, is quite simple:

Work on the distribution of the solution begins only after full drying of the primer.
Plaster tintable in mass. Keep in mind that as it dries it darkens a shade roughly two shades. To avoid gaps, the primer also needs to be pre-tinting.
According to the prescribed technique, is the partial application of the solution on the surface, the thickness is 1-2 mm. with the rapid setting of the plaster, the area of treated surface shall not exceed 2 m^Two.
?It is important! Between the sections of the application form torn seams. This technology will make them virtually invisible.
The direction of movements on the distribution of the plaster pile roller depending on the texture you plan to after work.

The application of textured roller slightly changes the technique of applying finishing material:

First, the surface is fully executed with decorative plaster. The layer thickness varies between 1-2 mm.
Then the application of any of the picture using the textured roller.
All movements are produced in compliance with strict Parallels.

According to the proposed technique allowed the option, when the roller at the same time to apply a layer of plaster, and the pattern is formed. During the day the plaster dries, then move on to applying a protective coating. In this role, the wax, its application is carried out with a roller with medium pile. In conclusion, woollen cloth is carried out polishing of the surface.

The method of spraying ↑

Interesting is the end result when using the technique of spraying decorative material. This method is applicable both for external finishing works and decoration of the interior. Application technique is simple and involves the following steps:

Initially, the spatula is formed smooth starting layer. Only after complete drying of the first layer proceeds to the next step.
For the second layer apply various adaptations. It can be a brush, a brush with hard bristles or even mesh.
When choosing a brush, dip it in a solution of plaster, and then distribute the mixture by tapping the tool on the stick.
The technique of applying a decorative material with a brush is a kind of cleaning tool from the solution with a stick.
For facades applied grid through which the solution jumps decorative plaster with a spatula on the wall.

The technique is clearly shown in the figure below:

If you wish to improve the process, the first layer can be made a little darker, and the final distribution to take decorative material is more light shade. A different texture is obtained by treating the surface of the second layer without waiting for drying of the starting finish.

The original technique of spraying is clearly described in the following video:

The use of scrap materials ↑

Design options of decorative plaster surfaces with the use of improvised means a lot, most of them can learn, even a novice master.

The technique of hatching resembles the formation of «rain» from decorative plaster woodworm:

First, there is the application of a smooth layer of finishing material.
Not waiting until the solution dries, it is treated with a metal brush.
After 24 hours, the excess of plaster is removed with a spatula or sponge, depending on the size of the roughness.
If the solution does not kolarovata in mass, produce surface staining.

Much more difficult to work the technique «Sgraffito». For applying required plaster in different colors, the main thing – that they blend together. First, the surface in several layers processed colored decorative material. After drying, using a sharp spatula or chisel to separate the sections of the layers partially removed. With this technology looming on the wall of unique patterns that have similarities with applique. In conclusion, the decorative finish is exposed to neat grinding.

Another original idea of design of structural surfaces is suggested in the following video:

The application of Venetian plaster ↑

The desire to decorate the wall with Venetian plaster assumes the presence of skills in the application of decorative finishes. Newcomers to master the technique immediately will be difficult. Materials you must have:

a primer for Venetian plaster;
itself decorative mixture;
wax;
a container of warm water.

Trowel and sandpaper fine grit – the main tool for applying and processing. The entire process is the successive application of layers on top of each other, alternating these steps, the grinding surface.

Comment! A mandatory requirement of high application of Venetian plaster are perfectly smooth walls.

The main stages of work the following:

Priming the walls is a special compound designed for selected decorative finishes.
Tools are selected from stainless steel, otherwise the plaster will appear rust.
The application of decorative material to a dry surface is held small areas, the estimated area is 1 m^Two. Work begin on the upper corner.
Base layer make the minimum thickness. A spatula is pressed against the wall at an angle of 20-30^on, the direction of the movement – the semicircle. The first layer does not need polishing, he is given time to dry thoroughly.
According to the adopted technique, applying the next layer of plaster is chaotic movements to the strokes did not find each other. The tool needs regular rinsing with warm water.
Then the plot level large putty knife, sandpaper processing occurs after the drying of the wall. Dust is removed with a damp cloth. Depending on the desired result, the number of layers varies from 5 to 12.
To the next stage of placing the surface of the Venetian plaster begin a week later. Complete decorative finishing will give waxing. Selecting mother-of-pearl, gold or silver material, the wall is treated in any convenient way. Application technique permits the use of a putty knife, cloth or gloves with pile.
At the final stage polishing, using a machine equipped with a nozzle with a NAP. In its absence suitable woolen piece of fabric.

Insufficient experience any of the above-mentioned techniques for applying decorative finishes can be tested on the sheet of drywall. Detailed steps for working with Venetian plaster can be studied in the following video:
