Why does my gouache fall off when it dries?

It is recommended that you do not draw on cardboard.

Cardboard is not the same as gouache paper. Gouache pigments are actually very fine particles. When you draw on cardboard, the water soaks into the paper while the paint rests on the surface. The surface of the cardboard is smoother and less elastic.

So, as soon as the pigment dries, it may crack.

Besides, I don't think you're very skilled, so you have to be thick in color.

Too much pigment is used.

The water and pigment are not in the right harmony.

Try feeling the color with your hands.

Feel it with your heart. Just a suggestion, hope it helps.

Gouache is a powder pigment, it does not contain glue, the pigment in the paint box is added with water-soluble glue, but it will evaporate as soon as it dries, and the surface of the cardboard is smooth, and it cannot be fixed, so it is recommended that you use acrylic to paint.

You're gouache paper!! Depressed.

Compared with gouache paper, there are differences in the thickness, texture and texture of the cardboard. This one is related to the paper, the water absorption of the cardboard is worse than that of gouache paper, and the adhesion to the gouache color is also relatively poor.

In addition, whether it is a dry painting method or a combination of dry and wet painting, the color should not be too many times, otherwise the paper or with too many colors and gouache will affect the adhesion of the final color.

Finally, if you use too thick colors, even if you are painting on gouache paper, it is inevitable that the colors will dry out. Personally, I think that the expression of color or texture of the picture should pay attention to contrast and change, and it is not necessarily better to have "more" and "thicker".

Are you wearing too heavy colors?

Summary. Hello, the treatment method after the gouache paint is dried depends on the degree of drying of the pigment, and the appropriate treatment method is selected according to different degrees. If the paint is dry, you can poke it with the tip of the brush first, and if it can still be poked and the brush still has paint on it, you can poke a few holes in the paint that has been dried, sprinkle some water in the holes with a small watering can, and let the paint sit for two days before you can use it again.

Gouache is the abbreviation of gouache pigment, which has many kinds of names such as "propaganda color" in China, and the coverage is weaker than that of acrylic paint (or "concentrated advertising paint"). It belongs to a special kind of lucha in watercolor, that is, opaque watercolor pigments. Because it is cheap, easy to learn and easy to use, it is often used as an introductory painting material for beginners to learn color painting, and its usage simulates oil painting techniques or watercolor early wheel eggplant techniques.

Thank you. I hope mine can help you, if you are satisfied with my service, please give a thumbs up oh wish you all the best

What to do if the gouache painting is dry.

Hello, wait a minute.

When the gouache is dry, then spray with fixing solution to save or spray with fixing solution to mount. Gouache is a type of painting that is made by mixing water with powdery pigments. Its performance is characterized by being between opaque and translucent, and the color can produce artistic effects such as gorgeous, soft, bright and rich on the picture.

The presence of powder limits the fluidity of the water. When the gouache and silver painting is wet, the saturation of the color is very high, and after drying, due to the effect of the powder and the loss of luster of the color, the saturation is greatly reduced, which is the limitation of its color purity. After spraying fixing solution or varnish, the saturation of the color can be restored, and it can be stored for a long time without mildew. Copy.

Gouache is water-soluble, and can generally be attached to the paper and plastic board.

Suggestions: 1. After drawing on the zhi plastic board, spray the fixing solution to prevent it from falling off prematurely;

2. Do not store in direct sunlight and in a place where the temperature is too high to prevent it from falling off;

3. It is best to use oil paint paint, oil paint has a wide range of application, can be well attached to the plastic plate, and should not fall off when dry.

Right! If you are afraid of being expensive, or acrylic paint is not easy to buy, you can add an appropriate amount of white latex, and the color of white latex and pigment will not change after stirring well, but it will dry relatively quickly.

I can't draw it, it will crack when it dries, use acrylic.

Or brush the board with latex.

The plastic board is first brushed with acrylic substrate, and the surface is plasticized with a plastic machine after gouache is painted.

Do you brush the plastic first, then paint, gouache? This one is too difficult, try something else.

When the gouache dries, it will definitely fall off, and only oily pigments like oil paintings will not fall off.

Try acrylic, it's pretty much the same anyway.

Summary. Watercolor painting is an art form that uses water as a solvent and paints on paper with a brush. Since the pigment of the watercolor painting is mixed with water, the pigment may penetrate the paper before the watercolor is dry, but after drying, the pigment should be able to hold on to the surface of the paper and not fall off easily.

Of course, the use of different paper materials and pigment brands can also affect the waterproof performance of watercolor paintings.

Watercolor painting brother Wang Wei is an art form that uses water as a solvent and paints on paper with a brush. Since the pigment of the watercolor painting is mixed with water, the pigment may penetrate the paper before the watercolor is dry, but after drying, the pigment should be able to hold on to the surface of the paper and not fall off easily. Of course, the use of different paper materials and pigment brands will also affect the performance of watercolor waterproofness.

I'm sorry I don't understand, but can you elaborate on that?

Watercolors will fade on paper, especially if the paper is not thick enough and absorbent. Therefore, the selection of high-quality, thick and strong absorbent paper, as well as high-quality watercolor paints, can better maintain the bright colors and not easy to fade. When preserving paintings, you should pay attention to the environment and method of placement, and avoid the influence of direct sunlight, humidity and other factors.

Gouache. Dry and spray on.

Fixing fluid. Save or spray fixing solution to mount.

Is it a gouache painting that is not finished? Got a lighter color? Recommendations:

Continue drawing with dry drawing.

Spray a small amount of water with a sprayer and continue to finish.

If you are too lazy to find a sprayer, you can also use a brush (or a large pen) dipped in water to brush it gently.

1. The brushstrokes are restrained and cannot be let go.

2. I am not confident in adjusting the color, and I try to adjust it dirty little by little.

3. There are too many white tones in the picture powder.

4. The dry humidity is too uniform, and the picture has no focus.

The brushstrokes are bold and affirmative, and do not repeat them; It should be meticulous, it should be summarized, and it should be drawn so that the atmosphere is not stiff.

The above is just a little bit of experience of myself who is not at a high level, I hope it will help you a little. The moisture is not as good as watercolor, and it is normal to feel a little dead when it is not breathable

The reason is simple:

First, the color is too thick, and the gouache is different from the oil painting. The former cannot be covered repeatedly, otherwise.

Second, when I went on the first time, I didn't draw according to the structure or the color tone was too thick, and the color was not accurate, and it was easy to be sticky when it was covered back and forth.

The fixing solution is very simple to use, as long as the color is dry, spray one side flat first, and then paint. Play bright colors. But sooner or later the cracks are out of the way.

Maybe it's because you're drawing too thick, and the gouache doesn't last long. Fixing the night doesn't do much. As long as you don't keep scrolling the picture.

Gouache painting shouldn't fade, you might have left the painting rolled, right?
