Despite its antiquity, plastering of residential and public premises is still very popular. This is due to the practical advantages of such a wall design, and an unusually attractive appearance. Do you want to make your home more beautiful without resorting to third-party craftsmen? Then DIY Venetian plaster is one of the most preferred options for you.
DIY Venetian plaster
Venetian plaster itself has existed for a couple of thousand years and appeared earlier than its current name. Back in ancient Rome, builders noticed that the waste of the quarries in the form of dust and small fragments can be used to prepare a finishing mixture, which, with a certain application technique, is in no way inferior to normal marble in appearance.
Subsequently, the recipe for such plaster became very popular in Venice during the Renaissance, and from there it carries its current name, which in the original sounds like stucco veneziano . Now let's figure out what kind of finishing material it is and what it consists of.
Venetian plaster in the interior of premises
The main component of Venetian plaster is very fine stone chips. Moreover, it can be not only marble, but also onyx, malachite, granite, quartz and other minerals. This stone crumb is bound together with the help of slaked lime.
However, lime has recently been replaced by a synthetic component - acrylic. Such a Venetian plaster in its appearance is in no way inferior to the "classical" composition, but at the same time it is much more convenient to work with it. Various dyes, also called colors, complement the mixture. They give the Venetian plaster a certain shade required by the owner of the room to be finished.
Important! If desired and given time, Venetian plaster can not only be applied, but also prepared by yourself.
To do this, you need stone chips, which can be obtained from the marble and granite workshop. Slaked lime can be found at a home improvement store, and color schemes can be found in paint and plaster stores. But remember that the factory formulations already have a mature recipe and certain properties.
This kind of plaster can be made by hand
Separately, it is worth considering the advantages and disadvantages of Venetian plaster as a material for interior decoration. Among the advantages are the following.

As for the disadvantages of Venetian plaster, then these include the high cost of the material, the complexity of the finish and the high requirements for the base coat - it must be perfectly flat and well putty, without irregularities and defects. Without the last factor, you may face a problem when all the imperfections of the wall will be visible after finishing the finish.
Marble decorative plaster
A wall finished with plaster, depending on the type of material, may have a different texture, color, look modest and discreet, or, on the contrary, very expensive.
Marble decorative plaster is one of the types of decorative surface finishing. It is used for various purposes, including for facades.
Before proceeding with the description of the techniques for applying Venetian plaster with your own hands, we will familiarize ourselves with the list of tools required for this work.

From the description of Venetian plaster, its features, advantages and disadvantages, let's move on to considering the basic application techniques. But before that, check out how to prepare the walls for finishing work and how to independently obtain a composition of a certain color.
Important! As mentioned above, decorating walls and other surfaces with Venetian plaster is a complex process that requires some experience and skill. Therefore, before starting construction work, take a small amount of the composition and practice on white and smooth MDF panels. It is advisable to try several different plastering techniques and experiment with several colors.

All plastering work start with preparing the walls. If there is any old finish on the walls (paint, wallpaper or something else) - remove it completely and as thoroughly as possible. Also, the walls are cleaned of involuntary traces of repair in the form of stains and construction dust.
Removing old paint from the wall
After removing the previous finish, proceed to fix major defects in the wall. Cover cracks and potholes with a cement mixture, remove the protrusions with a grinder, rub the rough spots with sandpaper.
As a result, you should have a relatively flat surface without any special flaws, suitable for further finishing work.

Then apply a primer, starting and finishing putty on the surface in sequence. After sanding with the last sandpaper, you should have a perfectly flat wall, free from any flaws. Remember that all imperfections in the surface after finishing the Venetian plaster will be very noticeable.
Plastering the wall
Finish preparing the wall for Venetian plaster by applying two (and in some cases three) coats of primer.
Moreover, its color should be either neutral white, or close in shade to the future finish.
Before starting the finishing, the owner of the premises or the craftsman performing the work for him must select the color of the future Venetian plaster and "prepare" it using the base white a mixture and several different dyes. This process is called tinting, and from the step-by-step instructions given in this subsection, you can familiarize yourself with how it happens.
Step 1. Select a suitable shade of Venetian plaster.
When doing this, use a tinting fan. Not only basic colors are applied on it, but also their shades, the total number of which can reach several tens or even hundreds.
Step 2. Prepare the tinting tools - a blank sheet of thick paper on which you can see if the prepared Venetian plaster matches the selected shade, a small container for mixing the composition, a narrow spatula and a set of dyes.
Prepare everything you need
Prepare a small amount of neutral white Venetian plaster. Choose the right dyes. In this case, the master will achieve a dark red hue with an offset to brown. For this, basic red, red-brown, brown and black dyes are used. The latter is necessary to reduce the brightness of Venetian plaster and make it more similar to natural marble.
Preparation of neutral white plaster
Step 4. Select the container with the base color (in this If it is red), shake it up and add a large amount to the white plaster.
Adding the base color
Step 5. Stir the plaster and the color with a narrow spatula until the composition is uniform in color ..
Next, you need to mix the plaster and the dye
Step 6. Using a narrow spatula, apply a small a strip of plaster mixed with the base color. Compare it with the desired shade on a colored fan and determine which dyes and how much to add. In total, during the tinting process, several such checks will be made, with the help of which you can gradually achieve the color that you originally intended.
The plaster is applied to a white sheet
Step 7. Add a second color to the plaster that will displace it shade to the previously selected one. In this case, we are talking about a red-brown color. Just like last time, stir the plaster until smooth, apply a small strip of the mixture to the paper and match the color with the selected shade on the fan.
Adding a second color
Important! When giving color to the plaster, keep in mind that after drying, it will be lighter than at the moment, by one or sometimes two tones.
Step 8. Add literally a few drops of black color to the plaster to give a better match to the natural stone and slightly reduce the brightness, which will be unnecessary for this finish.
Step 9. Apply a strip of plaster to the paper and match with the selected shade. Adjust the mixture with dyes until it reaches the desired appearance.
After that, the tinting can be considered complete - then you will prepare Venetian plaster according to the same principle, but on a large scale, for application to the wall.
Comparison of shades
Let's start by looking at the basic technique of applying Venetian plaster. It is called classic and requires a mixture of only one shade. In this case, the Venetian plaster of the color of milk chocolate will be applied.
Use tinting to prepare some plaster of a certain shade and select the place where it will be applied. Please note that "Venetian" dries quickly, therefore work with small areas of about 1 m 2 . Different places should overlap a little.
The example uses a training canvas
Important! If Venetian plaster is applied by two different people, then from time to time they should change places - each has its own way of working, but at the same time it is necessary to achieve approximately the same appearance of the walls and their individual parts.
Apply the first layer of Venetian plaster with a smooth, rounded motion using a trowel. It removes invisible wall defects, levels it out and acts as a link for subsequent finishing layers.Remember to apply a small amount of plaster and a thin layer. At this stage, the presence of small bald spots is acceptable.
First coat application
Wait 60 minutes until the first coat is applied the Venetian plaster will dry out.
Then wait about 60 minutes
Step 4. Apply a second layer of Venetian plaster using a trowel ...
It should be as thin as the previous one, but at the same time form veins and other elements here, which in the future will become a "pattern" on the wall, imitating natural marble or any other stone.
Applying the second layer of plaster
Step 5. Apply the third layer of Venetian plaster, which in the classical technique called "rubbing". For this work, use a Japanese trowel, while pressing it against the wall with considerable effort. Using this tool, apply a small amount of plaster over the second layer, and immediately make movements to remove the excess.
Third layer application
Venetian plaster area after application and partial drying third layer. You can notice a specific pattern, which is the main feature of this type of finish.
Step 6. Without waiting for complete drying (but not immediately after application), grind the third layer of abrasive Venetian plaster a sponge or very fine sandpaper. Shake off any dust from the wall to be treated.
Grinding the third layer of plaster
Step 7. After the finishing layer of plaster has dried, wax it. A small amount of it is applied to the spatulas according to the same principle as in the previous operation - first the composition is on the wall, then its excess is removed with pressure. Wax will make Venetian plaster one tone darker, give it a shine and protect it from abrasion and moisture.
20 minutes after waxing, the section of the wall finished with Venetian plaster wiped with a dry and clean cloth. Before that, you can "grind" it again with a Japanese spatula, removing excess wax.

Now let's consider a slightly more complex technique of applying Venetian plaster - here the work goes with mixtures of the same color, but different tones - one lighter and the other darker.
Step 1. Using tinting, prepare a certain amount of plaster of the same color, but in different containers and with different shades.
As mentioned above, the first composition is lighter, the second darker.Also define an area of 1 m 2 where the Venetian plastering will begin using this technique.
Prepared plaster in two shades
Step 2. As in the previous technique, apply the first layer of Venetian plaster with a Japanese trowel in rounded strokes with medium pressure and without much removal of excess. When doing this, use a mixture of light colors.
Apply the first coat
Step 3. Wait for the first coat to dry and proceed with application second. He will be responsible for the texture of the wall decoration with Venetian plaster. Apply the main part of the second layer in a light tone, drawing out veins and other elements small in height. Then take a small amount of dark-colored plaster with a Japanese trowel and leave small spots and streaks on the surface.
Thus, form a certain pattern by copying the real stone.

Apply a third coat of light colored plaster. At the same time, work with a spatula with serious effort, in semicircular movements, "on the scratch" of the newly applied plaster. Then polish these areas. The process is similar to what happens when describing the previous finishing technique.
Applying the third coat
Wait until the third coat of plaster is dry and treat the area walls (or, in this case, a training canvas) with an emery cloth or sponge.
Surface treatment with a sponge
Step 6. Wipe off the dust remaining on the plaster section of the wall after use with emery sponges, and apply a coat of wax. As soon as it dries up, wipe everything off with a dry and clean cloth. After that, a section of the wall can be considered successfully plastered with a "Venetian" in two tones.

Important! Apply a two-tone plastering technique, taking into account the size of the area to be trimmed. If it is large, then the difference between the shades should be minimal - otherwise the wall will “dazzle” and rather annoy than evoke positive emotions. But for small areas, it is allowed to use plaster with a difference of several tones.
And, finally, let's get acquainted with the third technique of applying Venetian plaster - imitation of real marble.
Please note that this is a rather complex finishing option that requires some experience in this area.
Step 1. Prepare the base color plaster (in this case, the red that was discussed in the tinting subsection), as well as black and white mixtures, with which the imitation of marble will be performed. Apply the first layer of Venetian using the base shade composition. In this case, lay the plaster on the surface diagonally from right to left, leaving characteristic stripes.
First coat is applied
Step 2. Wait until the first coat is dry and apply a large amount of base color plaster to the trowel, add some white mixture to it and stir gently. Then complete with black composition. An example of applying three shades of plasters to a trowel can be seen in the photo below.
Example of applying three shades of plasters on a trowel
Apply a mixture of three plasters of different colors the second layer. When doing this, slide the trowel diagonally from right to left, drawing a streak of streaks.
Applying the resulting mixture
Step 4. Using the instructions from the previous step, continue applying the multi-colored mixtures of plasters until the second layer is completely formed. Let it dry.
The second coat must dry
Step 5. Sand the Venetian marbled plaster with fine-grain emery cloth ... Wipe off any dust generated during the work.

Step 6. Apply a layer of wax with a Japanese spatula to protect the plaster and give coating shine.

Step 7. After the wax has dried, wipe the surface with a clean cloth or a special nozzle for grinders.
At the end the surface is thoroughly wiped
