The interior of any room is made up of little things. Sometimes, in order to create the right atmosphere, craftsmen have to use art materials such as gypsum. This material is used for both finishing and decorative work. Gypsum powder diluted in water hardens quickly, is accepted by any company, which is why it is so highly valued by all builders.
They try to paint it when its naturalness cannot harmoniously blend into the overall concept. To get rich light, acrylic paint must be applied in several layers, at least three... But this is not the only way to change its color.
Gypsum varnish will also help to give the desired shade or make the surface glossy, it lies flat and dries quickly, evenly paints the surface, does not flow, does not create streaks. If a person needs to shade a plaster relief, varnish is exactly the tool that will help quickly achieve the desired effect.
The material perfectly accepts gold and silver pigments, if you want to make the room more festive, bright, you can use gold powders that are diluted in water.
Painting gypsum with acrylic paints is also popular, they mix well with the composition, if all the rules of work are observed, they get a thick, evenly colored mass, with which you can work without adding additional color fixers.
To accurately answer the question of how to paint gypsum, you need to look at the purpose of the material. If, according to the idea, you need to make a bas-relief, it is best to work with acrylic paint, which will be applied to the frozen composition.
To prepare for work, you need to make sure that the condition of the paint is normal, for this it is enough to open the can and mix the composition. Clots that float to the surface will indicate that it was not stored correctly, or it has expired.
High-quality gypsum paint is not too liquid, it should mix well with the base material. If the pigment is added directly to the composition, you need to find a large container and a long stick for constant stirring. This is the only way to carry out the procedure correctly and get a good effect.
All dyes for plaster can be found in an art salon, often it is there that paints of the desired shades are sold, because by mixing colors, you can get an incredible option that fits perfectly into the interior.
In order to have a good idea of the process of painting plaster, you need to follow the sequence of actions. First of all, the composition is prepared, it is necessary to fill in the dry powder with water strictly according to the instructions, otherwise the person risks getting too liquid or, conversely, a pasty composition with which it will be impossible to work.
If you plan to add pigments for gypsum immediately, you need to do this carefully, gradually adding paint to the mass, stirring the resulting mass and assessing the brightness of the color. It should be noted that the hardened gypsum becomes somewhat paler, if you want to get a bright effect, additional coating may be needed.
To understand how to paint plaster after hardening, you can recall drawing or labor lessons. Diluting thick paint and working with brushes of different sizes, a person alternately paints over all the elements, trying not to break out of the border and not to hurt unnecessary details.
In some cases, you can try patinating plaster - aging is performed in several ways, one of the most popular is working with paint and sandpaper. The surface of the plaster is covered with paint of a dark or light shade, depending on the desired result, after which the dried layers begin to gently rub with a sandpaper. Such effects of antiquity make the relief more interesting and the idea original.
Painting a decorative gypsum stone is carried out not only if its color does not quite match the interior elements, but also when defects appear on the material over time, which worsen it appearance... Thanks to the protective properties of the applied paints and varnishes, it is possible to provide the tiles with resistance to erosion destruction and give the finish an attractive appearance.
Acrylic, silicate and silicone paints and varnishes (LKM) are used to paint artificial gypsum stone. Most often they are water-based. For painting products intended for finishing external walls, paintwork materials are used that are resistant to external influences. Gypsum tiles can be painted in bulk, that is, the coloring pigment is added to the solution before casting the molds. The whole product gets the main shade. This method is used for installation in places where mechanical damage to the coating is possible.
For surface application of color, acrylic paint for gypsum is most often used. Ready-made solutions can be purchased at the store or made yourself using colored pigments. The combined use of these methods allows you to get the effect of natural materials used for decoration.
In order for the paint to adhere better to the surface, it is treated with penetrating primers, and to protect the material from fungi and moisture, gypsum products are impregnated with water repellents. Their use reduces water absorption by 20-25 times. These solutions are applied after the tiles have been varnished or painted.
Silicate and silicone paints are mostly used for outdoor use. The binder is water glass and silicone resins. The service life of such a coating is about 20 years.
To create a matte or glossy surface of the material, water-soluble varnishes are used. In addition, they protect the surface of the gypsum stone from abrasion during operation. For creating durable coating varnish is applied in several layers. It should be remembered that after such processing, the main color of the plaster product darkens.
It is not difficult to paint a decorative gypsum stone with your own hands. The main advantage of such works is the choice of colors and materials. Decorative stone paint should be in harmony with the interior elements. Gypsum products can be colored like stone or imitate brick and wood. Tiles can have several colors with a smooth transition from one to another.
Indoors, water-based tinted varnishes are used for painting. For this, paintwork materials are suitable for gypsum and stone, and if not, colorless for wood. You can pre-assemble the drawing on a horizontal plane and, if necessary, correct the defects.
For work, brushes of various sizes and shapes are used. Cannot be used for application decorative paint rollers or paint brushes(maklovitsy), since the consumption of paintwork materials increases greatly, and smudges remain on the tiles. A spray gun with a compressor is well suited for work. The use of such a tool reduces the consumption of paintwork materials and allows you to cover the tiles with an even thin layer of paint.
To darken the relief areas of the gypsum stone and eliminate defects, a brush or airbrush is used. The latter can shade the main color and make smooth transitions between tones. However, not everyone has such electrical tools, and when large areas this work takes a long time. At the same time, quality always suffers, which is a disadvantage of self-painting.
There are several ways to add color to gypsum stone. The most commonly used hand painting with a brush. Each tile is painted with a base color and then several tiles are highlighted more dark shade... During the application of paint, care must be taken to ensure that no smudges form and no unpainted fragments remain. This method is laborious and time-consuming, so it is used to paint a small amount of tiles and eliminate defects.
The use of electric and pneumatic tools facilitates the work. Painting plaster products with a spray gun is popular among professional craftsmen. To do this, the tiles are laid on a horizontal surface 1x1 m in size and sprayed base layer... The technology for applying shades is simple: after the tiles have dried with an airbrush or a spray gun with a thin nozzle, a layer of paint of a darker color is applied to individual areas.
Some experts believe that it is best to paint the tiles laid on the wall. This makes it possible to place darker pebbles over the entire treated surface. The paint applied to the plaster dries quickly, which helps to immediately identify and eliminate defects. After that, the tiles are varnished. With this surface treatment, it is easier to care for the product, since you can wipe the gypsum stone with a damp cloth without fear of smearing the paint.
Plaster painting can be carried out both during the manufacture of the product and after. In the first case, the pigment is added to the mixture or directly to the mold, and in the second, to the paint. It is difficult to find the same color of plaster mix in large volumes. Therefore, this method is used for the piece production of a small amount of tiles.
It is easier to prepare paint using dry pigment or liquid color. It is not recommended to mix several colors to obtain the desired shade, since when mixed with paint, colored stains may come out. With a large amount of work, it is simply impossible to get the same color.
If a dry dye is used, then it must first be dissolved in water and then added to the paint. For the preparation of the background and shading mixtures, different containers are used. If the tile is painted like a brick, then the shading color is most often made lighter than the base color. Before applying the next layer, each time it is checked whether the previous one is dry. It must be remembered that after the product dries, its color becomes lighter.
Many parents try to give their little ones the best. All girls and boys, regardless of age, love to draw on everything that they first come across. In order for the children to have something to do and at the same time without the slightest harm to the environment, it is best to direct their creativity in the right direction. Therefore, master classes for children are organized.
To paint plaster figures, you should stock up on the figures themselves and paints. You can choose the most different figures, depending on the age of the child and his capabilities:
To paint the figures more conveniently, it is best to put them in a small amount on plastic plates, so that the kid can draw calmly and at the same time not get very dirty. For painting small details, it is best to use thin brushes, but wide ones are useful for varnish. Plaster figures are best painted with brushes made of synthetic material. If the figures have very small details, then it is best to paint them with paints from small tubes.
When the figures are dry, they must be covered with a shiny varnish, and reverse sides clean it with a metal nail file.
Painting plaster figures is a very useful activity for children, because with the help of such a fun and interesting entertainment, the baby learns to be more accurate and accurate. Plaster figures vary in complexity and size, so even the smallest crumb can safely draw with their parents.
By painting plaster figures, children not only have fun, but also prepare their hand for mastering writing, form their skills, coordination of movements, and muscle memory. Being engaged in painting constantly, children learn to be neat, and their movements become clearer.
In addition, the child forms his imagination, works with paints. The child's creative imagination should be formed from childhood so that he can harmoniously combine different shades, navigate in space and have an idea of volumetric thinking.
Painting figures will be an interesting activity not only for older children, but also for the smallest. Already starting from 18 months, the baby can be given a brush in his hands and together with him draw and paint figures that will become wonderful toys. This activity will also appeal to adults who like to be creative.
Such a mineral material as gypsum is widely used not only in medicine and art, but also in construction. In particular, from the gypsum solution is poured various materials for interior decoration. Gypsum-based mixtures are used as plaster. What kind of material is this? What are its features, advantages and disadvantages? And also, is it possible to color plaster products and how to paint plaster?
Decoration Materials for interior decoration made of plasterPlaster of paris is obtained from gypsum stone, previously fired and ground into powder. Then it is kneaded to obtain a pasty mass, better known as alabaster. It is widely used for construction and repair work, the manufacture of various decorative items, as well as binding materials at the intermediate stages of construction and repair work.
It is gypsum mortar that is most often used for modeling and stucco molding, the production of small architectural forms, pouring decorative tiles or artificial decorative stone (brick).
The mix quickly sets and hardens. Therefore, you need to be able to work with him in order to have time to implement your plans. The working substance has a white tint.
The material is quite simple to prepare and use, affordable and has a wide range of applications. Another advantage is environmental safety (since it is made from natural raw materials). He is able to "breathe", maintaining a certain level of humidity.
The use of gypsum materials in interior decoration premises are very, very popular. With its help, you can create real interior masterpieces.
The use of decorative gypsum bricks for interior cladding It is not superfluous to mention the following properties of the material:
However, in use, the gypsum base shows itself in different ways. Alabaster, unfortunately, is afraid of water (since gypsum powder dissolves precisely in water), is subject to abrasion and mechanical stress.
To increase the strength of gypsum materials, manufacturers use various strengthening additives (plasticizers, acrylic, polyvinyl acetate glue).
So today there are several brands of gypsum on sale, differing in the degree of compression holding. The highest grades are used in the production of decorative elements, even for the facade (exterior) decoration of buildings.
Application:
If desired, gypsum materials can be given a completely unimaginable look, including simulating naturalness (for example, wood). Various technologies of toning, coloring, "aging" are used here.
Marble tinting. A well-dried gypsum product is impregnated with heated drying oil or shellac-rosin alcohol solution. The impregnation fits well, without streaks, creating protection from moisture. The gradually dried primed surface acquires a resemblance to aged marble.
Thanks to tinted plaster decor, it easily imitates marble Wax tinting. An impregnation is used, consisting of wax dissolved in turpentine (gasoline) with a slight addition of yellow oil paint... After the impregnation has dried, the surface is rubbed to obtain a glossy finish.
Ivory tinting. A soap maker, nitro varnish and a little yellow oil paint are used. The surface is dull by rubbing with talcum powder.
Patination. Various shades of brown or brownish green are selected and mixed with other substances. It is recommended to paint in three layers, moreover, in the depressions, processing usually occurs with a mixture that is more viscous in consistency. The technology of applying the coloring matter itself is also important here:
Such additives will help to shade or enhance the imitation: bronze powder, talc and chromium oxide, graphite powder, sienna, ocher, umber, soot, green cobalt, lead or. These are all semi-professional methods of painting gypsum-based materials. Traditional plaster paints are available on the market.
The most commonly used dye mixtures for internal works- acrylic aqueous emulsions or dispersions. After drying, they create a strong protective film that protects the base from moisture. In addition, all water-based paints are environmentally friendly, which means they can be used inside any premises, including residential ones.
When making decorative bricks or a stone based on gypsum, the working solution is tinted. For this, various pigment powders are used. Tinting of the solution makes it possible to obtain a finished brick, uniformly colored throughout the entire structure (then operational defects will be less noticeable).
To create an imitation of texture (veins), paints of several shades of color are used. And to increase the protection of the surface made of gypsum brick or stone (after all, gypsum is by its nature quite fragile), the finishing varnish coating will help.
Experts advise not to delay painting the gypsum finishing elements, as the adhesive properties of the materials deteriorate over time. If this has happened, then it is not superfluous to use a primer, and only after painting. The primer will also increase the strength of the plaster base and provide some protection against moisture penetration.
Building gypsum is unlimited possibilities for original interior decoration. The widespread availability and ease of use made the material very popular. And having paints, red lead, varnishes, gold leaf and other pigment substances in your arsenal, you can achieve real palace luxury.
Sometimes there is a strong desire to change something in the design of an apartment or house. In this case, you can use gypsum stone, the painting of which is not as difficult as it seems at first glance. The use of decorative stone will allow you to transform any room, but first you need to understand the intricacies of staining the material.
If unprocessed products are purchased for finishing, or the material is made independently, then the products need painting. The first step is to test the selected compositions in order to understand what color the result will be.
Painting is carried out using the following mixtures and solutions:
In addition, painting is carried out with other solutions: various varnishes and impregnations with a wet effect, paints that give the plaster stone a natural look.
The main thing is to determine the purpose of the material and, depending on this, select a dye.
Correct painting of gypsum stone implies adherence to simple rules:
When you follow these tips, it becomes possible to protect the decorative stone from negative influences, corrosion, and the paint layer will last for a long time.
To create a decorative element that attracts attention with your own hands, you must use the tools thanks to which the painting is performed.
The main devices include:
Most often, an airbrush is used for painting.
Its advantage over a brush is that it sprays the composition, rather than smears it, as a result, an even color is obtained without too dark unnatural areas.
With an airbrush, you can give the stone different shades - for this you simply adjust the flow of paint and the distance from the tool to the working surface. A conventional airbrush with a compressor equipped with oil cooling and an automatic pressure regulator is suitable for painting the material.
It is very rare to paint the entire facing stone with a brush, because the device leaves streaks and ugly stains. The brush is a great tool for highlighting areas.
Preparation for staining is carried out depending on the type of material: a previously used stone or a new one. The old corrosive layer is carefully removed from used products. The stone is then sanded to eliminate large surface drops. Facing elements are blown with a compressor and impregnated 2-3 times - due to this, during finishing, the consumption of coloring compositions will be significantly reduced.
The new stone does not need to be sanded and rubbed - it is enough just to wash it and soak it 2 times. In this case, painting will take much less time.
No need to use high-precision tools and special technologies to color the material. First, a composition is prepared from a dry powder, filled with the required amount of water indicated on the instructions from the manufacturer. If everything is done incorrectly, then you can get an overly liquid or thick solution - it will be rather inconvenient for them to paint textured gypsum stone.
In the process, you need to paint over all the details, without getting too far beyond the boundaries of each element. As it dries, the paint on the plaster will fade slightly. The surface should be varnished to provide protection. Decorative gypsum stone is painted with water-soluble paints, so the varnish is chosen with the same characteristics: alkyd, matte, pentaphthalic.
There are several methods of painting the material: in bulk and surface.
The first method is used when self-made stone. The technology consists in adding coloring pigments to the plaster solution - as a result, the product is painted over from the inside. To paint with this method, mix 1/2 part of the color with 200 ml of water and the same volume of acrylic primer. Matt varnish is applied to the required surface of the stone after complete drying.
The surface method is very simple: the finished facing material is coated with a coloring agent from a spray gun. The advantage of this method is the ability to give the decorative stone the desired shade, to create a natural, natural look.
There are several ways to paint the surface of a decorative plaster stone in an interesting way, with the help of which you can achieve an unusual look of the product:
One of the ways to paint decorative gypsum stone is presented in the following video.
