What kind of painting material is good for painting bright colorful pictures on the wall?

Acrylic paint and lacquer paint is the main, need to express special effects will be used when the gold powder, silver powder or glass and other materials. Depending on the specific situation, each material has its own attributes and advantages.

Acrylic pigment

Acrylic pigment belongs to the synthetic polymerization pigment, invented in the 1950s, which is made of pigment powder and acrylic latex. Acrylic latex is also called acrylic resin polymerization latex. There are many kinds of acrylic resin, such as methacrylic resin, therefore, there are many kinds of acrylic pigments. Foreign pigment manufacturers have produced acrylic series products, such as matte acrylic pigments, semi-matte acrylic pigments and glossy acrylic pigments, as well as acrylic matte oil, varnish oil, plastic ointment and so on.

Acrylic pigment is popular among painters. Compared with oil paint, it has the following characteristics:

(1) It can be released with water, which is good for cleaning.

(2) Quick drying. The pigment can be dried in a few minutes after the brush is put down, and it is not necessary to wait for several months to varnish after the work is finished like oil painting. Painters who like slow-drying pigments can use retarders to slow down the drying time of the pigments.

(3) The coloring layer loses its solubility quickly after drying and forms a tough, elastic, impermeable film. This film is similar to rubber.

(4) The color is full, heavy, bright and moist, no matter how to blend will not have a "dirty" "gray" feeling. The coloring layer will never have the phenomenon of oil-absorbing stains.

(5) The work is long lasting. Oil painting in the oil film is easy to oxidize over time, yellowing, hardening easy to make the picture cracking phenomenon. While acrylic gelatin film will theoretically never become brittle and never turn yellow.

(6) The biggest difference between acrylic paint and oil paint in the way of using is that it has the operation characteristic of general water-based pigment, which can be used as watercolor and gouache.

(7) Acrylic plastic ointment contains particles, and there are coarse particles and fine particles, which provides a convenient way to make texture.

(8) Acrylic pigments are non-toxic and will not harm the human body.

It should be noted that: acrylic painting should be painted on the base made of acrylic base paint (GESSO), do not use oil base for painting. Material experts also do not advocate the mixing of acrylic and oil colors, especially do not paint on acrylic base oil painting, which is mainly for the permanent preservation of the work. There is no adverse reaction between acrylic and oil paints, and when used interchangeably, their adhesion is subject to the test of time.

Lacquer pigments

Performance and application of natural lacquer

1. Performance of natural lacquer

(1) The lacquer film has excellent physical and mechanical properties. Such as film hardness, film hardness of 0.65-0.89 film value / glass value). And general synthetic paint film hardness is only 0.2-0.4. Film wear strength, wear resistance is better than any synthetic resin and other coatings. The gloss of the paint film is bright and long-lasting. Good sealing of the paint film, the paint film has very few pinholes. Good adhesion, strong adhesion to wood.

(2) The paint film has high heat resistance and good durability.

(3) The paint film is insoluble in any animal and vegetable oils and mineral oils, and is resistant to various solvents.

(4) The paint film has good electrical insulation properties and certain radiation resistance.

2. Application of natural lacquer

Because natural lacquer has the properties of anti-corrosion, anti-penetration, moisture-proof, mildew-proof, acid-resistant, etc., and the film has the characteristics of strong hardness, wear-resistant, and has a beautiful and durable luster, therefore, the lacquer is widely used in the national defense and military industry, chemical industry, petroleum industry, metallurgy mining industry, textile industry, dyeing and printing industry, the pharmaceutical industry, as well as the ancient buildings and cultural relics of the protection of lacquer, the lacquer is only a very small number of people. Lacquer is only a small part of the lacquer art.

The raw lacquer generally contains 20%-40% water and impurities, and must be processed and refined to be applied. Refined varieties of lacquer are raw lacquer, black push light lacquer, red push light lacquer and transparent lacquer, etc. Raw lacquer is also useful for raw lacquer and wiping clear with raw lacquer. The so-called "push light paint", only not oil class, hardness, push light-resistant paint.

Pigment

Natural raw lacquer is very picky about the requirement of pigment mixing, because natural raw lacquer contains lacquer acid, and all kinds of salt-based pigments are metal compounds, where zinc, barium, lead, copper, iron, calcium, sodium, potassium and other metal pigments, a natural raw lacquer mixing with the lacquer acid chemical reaction, darkening or even black, so it can't be used. Only the precious metals such as gold, silver, chin, mercury, etc., which do not have chemical reaction with lacquer acid, can be used in lacquer. In recent times, organic pigments extracted from refined tar, non-metallic, and acid and alkali resistance, it is appropriate to enter the paint. In ancient times, mineral salt-based metal compound pigments were mostly used, such as silver vermilion, ochre, stone yellow, stone green, stone green, lead powder, soot, etc. In fact, in addition to silver vermilion, stone yellow, stone green, lead powder, soot and so on. In fact, in addition to silver Zhu, stone yellow, soot, more than not suitable for lacquer, so the ancient lacquer color is darker. The origin of "green sinking lacquer" is due to the gray color of stone green into the lacquer and start. Into the paint pigment basically have silver Zhu, Lixol red (Western red), cadmium yellow, titanium white, phthalocyanine blue, phthalocyanine green and so on. Due to the appearance of titanium white and phthalocyanine blue, phthalocyanine green pigments, lacquer color can be blended with a variety of colors, plus the use of mud silver, mud gold, lacquer color is more rich.

All of the above pigments are dry color powder, which can be used only when they are mixed with lacquer. The method of mixing is: put the pigment on the paint mixing board, add a little oil, use the stone pestle and mortar to grind them in batches, and turn them over from time to time to clean them up, and make sure to grind them finely, which is very much related to the sharpness of the color. After grinding, then mix into the transparent lacquer or red push light lacquer. Generally speaking, the amount of lacquer should not be less than 50%, if the lacquer is too little, the color lacquer is not firm enough, and if the lacquer is too much, the sharpness of the color will be affected. After mixing pigment and lacquer, the color lacquer is generally darker than the original one after drying. However, after a certain period of time (a few months or even longer), it will return to the color of the modulation, which can be called restoration, but if the content of the paint is too large, the color will not be completely restored.

Metallic materials

Gold is gold. Gold can be seen as a yellow pigment, there are gold foil, gold foil powder, gold clay, gold nine powder and so on.

Silver is white silver and can be seen as a white pigment. There are also silver foil , silver foil powder , silver clay , silver pill powder and so on.

Aluminum is similar to silver and can be regarded as white pigment, and there are also aluminum foil, aluminum foil powder and aluminum clay.

Inlaid materials available in lacquer art inlaid materials are many. As long as there is a certain degree of hardness, sanding resistance, can be durable are desirable.

There are many kinds of shells, and the valuable ones are luminescent snails, abalone shells (rock jelly), pearl shells and so on.

In the lacquer art is commonly known as studs. China's southern lakes called bright ear of white mussel shells, skirt has a beautiful color, can also be used. Processing method is to remove the outer skin of the shell first, and then polished into pieces on the grinding wheel. The thickness depends on the need. Korean lacquer art is famous for its conch shells. Processing technology is more advanced, the first machine to separate the shell dissected into thin slices, thin slices can be cut into thin strips of varying widths, not only easy to use, the shells have also been fully utilized. The conch shell can also be processed into particles such as sand, which can be sprinkled and glued to the screen.

Egg shells are usually used eggshells, duck eggshells, quail eggshells. Egg shell color has

red and white, duck eggshell and green. Duck eggshell slightly transparent, adhesive eggshell primer can be lined on the surface, so darker than eggshell. Quail eggshell is thinner than chicken and duck eggshell, suitable for dry inlay area is small and precise part. Eggshells can also be crushed into particles, sprinkled and glued to the picture.

Metal gold and silver processed into thin slices, can be embedded in the lacquer.

Besides gold and silver, there are also tin, copper, lead and aluminum.

Other than inlaid sheet, can also be inlaid wire.

Horn bone horn bone, cow bone, camel bone, etc., can be used for inlay. The processing method of animal bone is,

first break it into two pieces, add lime and litharge in a pot of steaming to remove its oil, and then processed into thin slices, can be used. Turtle shell and tortoiseshell can also be used.

Wood and stone boxwood, rosewood, Shoushan stone, Qitian stone, Ye La stone, coral, green pine

stone, etc., regardless of price, as long as appropriate, can be used for inlay.

Abrasive materials abrasive materials are water sandpaper, grinding stone, artificial grinding stone, charcoal and so on.

Water sandpaper thickness has a variety of models. Domestic 280 #, 320 #, 360 #, 400

#, 600 #, etc., the larger the number of finer. Sailing brand (Tianjin), diamond brand (Shanghai) of water sandpaper is more durable. Japan, South Korea's water sandpaper more models, more fine, but also more durable. There are 800 #, 1000 #, 1200 #, 2000 #, etc., are now imported.

Grinding stone green marble, red marble, is a natural grinding stone, hard and fine, no sand, the Department of chiseling rock and get.

Man-made grinding stone has various shapes, various models, 400 #, 600 #, 800 #, etc.

Can also be used to sharpen knives, also known as the oil stone, hardware and chemical stores are sold.

Research charcoal pine, sycamore, beech, tsubaki and other charcoal is more suitable, the fineness is equivalent to 1200

# water sandpaper. Japanese lacquer art with charcoal is extremely careful, due to the thickness and there are a variety of, some for the initial grinding, some for fine grinding, some can be trimmed into a needle like a pen to grind the fine pattern.

Push the light, wipe clear materials

Ash that is fine tile ash, used to push the light. Titanium dioxide can also be used.

Vegetable oils such as peanut oil, rapeseed oil, soybean oil. Push the light with.

Hair ball Women hair ball, dipped in water mixed with tile ash can be wiped off the paint surface of the abrasion marks, and so dry is a fine grinding.

Skimming cotton for wiping clear, dipped in raw lacquer thinly rubbed on the lacquer. Skimming cotton is also used for filtering paint.

Thinners, detergents

Camphor oil camphor oil extracted from camphor, volatility is slow, into the paint can be flat brush marks, is the most reasonable

thinking thinners. But too much will affect the dryness of the paint.

Turpentine extracted from pine trees. Volatilization faster than camphor oil, also suitable for thinners. Oil painting is also used.

Alcohol, also known as ethanol, evaporates quickly, and is not suitable for use as a diluent, but is suitable for use as a detergent, used to wipe hands.

Gasoline is fast evaporating, suitable for detergent, and sometimes (such as for painting patterns) also used as a diluent.

Kerosene is slow to evaporate, and can be used as a detergent, and sometimes it is used to make the paint dry slowly, for decorative patterns.

Vegetable oil can be used as a detergent to clean paint brushes and paint brushes. It can also be used to clean the paint sticking to the hands.

Tung oil is a kind of dry oil, its oil film dries quickly, resistant to water, alkali and atmospheric corrosion. Since ancient times, tung oil has been widely used in furniture, construction, oil cloth, umbrellas and lacquer.

Tung oil to clear and transparent, color tender yellow or with green phase is good, dark yellow with brown for the second. Generally speaking, the new oil is better than the old oil. Raw tung oil film lack of toughness, luster is also poor, so the raw tung oil must be processed into mature tung oil, can be used. Lacquer tung oil is divided into two kinds of oil, oil, the former thin, the latter thick.

Auxiliary materials

Silk cotton in the paste gold, gold halo used for rubbing gold, silver powder.

Leather paper for filtering a small amount of lacquer.

Silk cloth, gauze cloth, chemical fiber cloth can be used to filter lacquer.

Powder lacquer lacquer lacquer blended into a variety of colored lacquer, coated in the glass plate 2 to 3 times, scrape down after drying, mashed and sieved, divided into coarse and fine, that is, lacquer powder. With cashew paint coloring coated on plastic sheeting, easy to come off, more convenient. Maki painting.

Charcoal powder Charcoal research fine sieve, pile of paint.

Sulfuric acid paper sealing good, cover the paint, paint.

Reproduction paper Cotton dipped in white powder rubbed on the paper, it will make its own reproduction paper. Can also buy ready-made red copy paper or blue copy paper. Copy the design with.

Soap is used as a detaching agent when stripping.

In the gourd lacquer painting process using paint, painting, hook, carving, filling, carving, skeleton, grinding, inlay, embedded and other techniques, with flat, bright, fine, uniform, colorful, elegant artistic expression. Craft types are carved lacquer inlaid jade, flat grinding studs, point screw, pure lacquer, bone stone inlaid, carved lacquer, carving and filling, color painting, grinding lacquer painting, lacquer flat inlaid and other ten categories.

The main techniques of gourd lacquer painting are:

Thin material: thinly coated with gold lacquer in the flat lacquer on the ground, to be lacquer at the time of drying will be in the, pasted on the gold or silver foil, bright colors and elegant, in the lacquer paintings, more than the performance of the sky, the river and other effects.

Oil paint

Oil paint is a kind of oil painting pigment, which is made of pigment powder, oil and glue. Most of them are sold in tubes, but you can also make your own.

Based on the production of raw materials and chemical properties of pigments can be divided into three major categories:

(1) Mineral pigments: extremely stable, strong light resistance, not easy to fade and discoloration, strong covering power, poor transparency, low purity, close to neutral. Such as ochre, raw brown, earth yellow, earth red and so on.

(2) Organic pigments: colorful and bright, with good dyeing power, transparency and color development. But poor light resistance, easy to fade in the sun. Such as red, rose red, lemon yellow, phthalocyanine pigments.

(3) Inorganic pigment: stable color, good light resistance, and will become gray after a long time in the sun. Such as titanium white, zinc white, ultramarine, sky blue, universal blue, cadmium color, cobalt color and so on.

The basic components of oil paint are pigment and binding agent. Most of the pigment powder used by the ancient masters originated from earth and minerals. Another part comes from plants or animals. The binding agent is made from resins, dry oils and fats, balsams and waxes, but usually linseed oil is used directly.

Common tools for grinding oil paint: a thick glass or marble plate, a milling mallet (research rod), a palette knife and a glass bottle or an empty tin tube for storing pigments

The specific method is as follows: pour the pigment powder on the glass plate, and if it is a block of pigment it should be pressed into a crumbly powder first, and then add the linseed oil slowly and grind it in a circle at the same time, and use the palette knife to blend it until you get the the characteristic consistency of oil pigments. It must be carefully ground to eliminate particles so that the pigment powder combines fully and perfectly with the linseed oil.

It should be noted that different pigment powders require different amounts of oil, and it is sufficient to grind the pigment powder into a paste. When mixing colors, pay attention to one principle: put as much color powder as possible, less oil. Generally use raw linseed oil to mix the color powder. It dries slowly and is easy to be useful for a longer period of time. If the painting needs to dry quickly, you can add 1:2 dammar oil 10% to the pigment powder. In the modulation of color, note that the only white color (especially zinc white) can not be mixed with pure oil, all other pigment pigment powder can be used in raw linseed oil modulation. White powder mixed with pure oil will soon change color, it is best to use emulsion modulation, can choose cellulose, casein emulsion binding agent. This kind of emulsion dries very fast, the modulated color must be sealed and packed, take as much as you need. For the coarser, particulate pigments can be ground fine while mixing the oil. For the oil color in the lead pipe, the oil can be absorbed before painting (such as squeezing on the newspaper, so that the paper absorbs the oil in the pigment), and Medium oil medium can be adjusted when used. For the light color pigment with strong chromaticity, it is necessary to mix and write the additives appropriately. Generally, we can use talcum powder, kaochen earth and other materials. For the color with strong covering power but opaque, you can also add appropriate amount of talcum powder and kaochen earth. This material only plays a role in increasing the volume without changing the role of pigmentation, can weaken the intensity of light colors or make opaque colors into transparent colors. For the pigment powder which floats after meeting water or oil, a little bit of cow bile or alcohol can be added appropriately, which can make the pigment powder have adhesion. The pigment with permeability should not be ground too finely, otherwise it will be colorful. When grinding toxic pigments such as lead, it is necessary to prevent the powder from entering into the nose. The pigment developed with linseed oil can only be applied to the covering layer when the underlying pigment is completely dry, so it can never be used to paint with extremely thick coating method, and is most suitable for one-time painting and single-color painting method. In order to change the disadvantage of this kind of pure oil pigment, it is necessary to add 10% resin polish and 2% wax dissolved in turpentine to linseed oil. The wax is added to increase the viscosity of the pigment (not necessary if poppy oil is used). At the same time it reduces the yellowing of the linseed oil and prevents the pigments, which have a high specific gravity, from separating from the oil. Some of the milled pigments may be slaked after a few days of storage and need to be further milled.

As for pigment powder (available in some domestic chemical stores and art supply stores), you can also make your own, and you can try to make it from any earth or mineral that you can see in your life that has a beautiful color.

Hand-painted wall production methods/steps and DIY hand-painted wall painting materials, production

A, hand-painted wall production methods/steps

In the wall according to the pattern of the approximate shape of the adhesive paper, which is designed to paint the pattern on the top of the use.

Step2: On top of the adhesive paper with a pencil draft, using dark markers to trace the lines to be used. Then carve out the shapes along these lines.

Step3: Spread newspaper all over the wall to keep the paint off the outside of the pattern.

Step4: In order to make the paint come out better, put a coat of white primer on the pattern first.

Step5: Spray or brush the color on the pattern area.

Tips:The pigment used to paint the pattern on the wall can be either propylene or wall paint.

Of course, there are many other ways to hand-paint a wall. If your painting skills are strong enough, then you can paint directly on the wall. If you are worried about your level of painting, you can also use a combination with advertising. In short, all roads lead to Rome, may you create a new home of your own.

Two, DIY hand-painted wall painting materials, production methods, attention to the main points and related knowledge

Full of creative hand-painted wall paintings produced a private landscape belonging to each family. And this landscape is not limited to a certain location in the home, like the bedroom, dining room, and even the bathroom can be chosen. But there are some points that we need to pay attention to when creating hand-painted wall paintings.

1, first of all, the pattern and color of the wall painting should obey the overall design style

For example, if your home is Chinese style, then the color of the wall painting pattern is required to be mainly more traditional black, red or gold. Patterns mainly from the traditional Chinese patterns and motifs, or patterns often expressed in Chinese painting.

Nordic minimalist design color is more extreme, wandering in black and white gray and super bright colors at both ends, so the corresponding wall painting pattern is mostly processed more abstract patterns.

Modernist design colors tend to be gaudy, the corresponding wall painting pattern is more realistic.

European design hand-painted pattern colors are more neutral, low-key, wall painting patterns mainly from the classical European decorative symbols, to match the performance of European furniture, wall lines.

2, followed by hand-painted wall paintings appear in the location also has to pay attention to

Generally we do not recommend that the whole room is painted with colorful patterns, that will make the space appear to have no level. You can choose a more dominant wall, a large area painted. This kind of hand-painted wall painting is made to appear as the main decorative face of the home, often bring a very great visual impact, the effect is very prominent and impressive.

The other is for some of the more special space for targeted painting, such as the sun room can be painted in localized with the sun, flowers and birds as the theme of the painting, painting a large tree in the stairwell and so on.

There is also a type of eye-catching, like the switch seat, air conditioning ducts and other corner locations. Painting refined flowers and natural foliage can often bring unexpected results.

3, hand-painted wall painting production method

Hand-painted wall production method is very simple, but the maker of the painting skills have certain requirements. So the following methods and precautions must be noted!

Materials for hand-painted wall painting:

Environmentally friendly paints of various colors, brushes, brushes, chalk, pencils, shabu shabu, a small area of the wall (beginners and art foundation of the weak best to choose a small piece of wall that is not very conspicuous)

Steps in the production of hand-painted wall paintings:

1. or complex, it is recommended to use chalk or pencil to make a good sketch first.

2. After sketching, use a liner pen to gently sweep away some of the traces. It is recommended that beginners should start with simple patterns, and then proceed to complex patterns after they have become skillful.

3. Start on the paint, according to the pattern line thickness and color on the size of the area, choose to use large and small brushes or row of pens, and then according to personal preference to paint on the paint on the OK
