Painted with acrylic walls, why is it unevenly painted

Really do not grasp well on the use of advertising pigment painting, acrylic paint waterproof and anti-decolorization advantages are only in a theoretical sense, in the actual home creation only bathroom and restaurant wall waterproof has practical significance, decolorization and discoloration is the problem of advertising color on the paper painting and strong light will appear, advertising pigment and acrylic on the gypsum wall effect is similar, you can first test a small area.

For technical problems, use a dim sum machine.

If it is on a powder wall, propylene is difficult to store for a long time. If you are on a wall that has been scraped with putty, you don't need to do anything special to protect it. The propylene itself has latex-like ingredients, and the putty powder is also stirred with latex, which is very compatible.

Usually all you need to do is wipe the dust with a clean rag. Watercolor is allowed to be treated before painting on the wall. The solution is as follows: Method 1:

Try peach gum (bone glue, edible gum can be) fully dissolved in water, diluted with water and evenly applied to the wall to be painted many times, let it fully absorb, and then brush after drying until the surface of the wall is completely dry and form a water-blocking diaphragm. Use a small amount of alum dissolved in clean water, draw on a completely dry wall, and then paint with watercolor, Chinese painting pigments or other water-based pigments when dry. After drawing, wait for it to dry completely, then apply the glue evenly and let it dry.

Pros, no technical requirements, disadvantages, trouble) Method 2: Apply diluted latex directly to the wall, etc. dry. You can paint with watercolor gouache.

Gouache coating needs to be thin). After painting, wait for it to dry, and then apply latex to fix the color. (Experience-based is required, because if you don't get it right, the wall will fall off).

It works. Acrylic paint that has been left out for a long time can be diluted by adding water or turpentine, if the caking phenomenon is too severe to dissolve, it cannot be used, and if it can be dissolved, it can be continued. Generally speaking, acrylic paints within two years can be diluted with water or turpentine, and in the process of dilution, the agglomerated acrylic paints need to rely on stirring to break up the pigments.

Acrylic paint that has been dried for 2 years can no longer be used, one because it has expired, and the other is because the pigment has already been quite agglomerate, and the water has long been unable to achieve the actual effect of dilution and moisturization.

You can use it, you just add some blisters for a while, acrylic paint is a water-based pigment, and the agglomeration is because the water in it is evaporated, just add more water.

The drying of acrylic pigment means that the chemical link inside the pigment has been completed, and this link is irreversible, which is also the characteristic of propylene. In other words, once the acrylic paint is dry, it can no longer be used.

Don't soak in gasoline and water, it's impossible, it's not enough to spend time and effort on money.

Buy some new ones and use them well, very cheaply.

It is recommended to use materials according to your needs, and if you can't use them up, you will basically waste them.

Hope that helps.

Yes, there is a place to buy art supplies that sells a transparent thing, you can go and ask, there should be.

It can be mixed with a small amount of gasoline, but it doesn't work well 、、、

Hehe, I've wasted a lot.

Acrylic, I think everyone is familiar with it. Now, with the continuous improvement of people's living standards, they have also begun to pursue art, which is different from buying a painting to hang at home. Nowadays, more and more people choose to paint a few pictures on the wall of their home, and traditional gouache paints and oil paints cannot meet this need, so acrylic paints came into being.

Today, I will give you a detailed introduction to acrylic, a new type of painting material pigment.

There are only three most common pigments on the market today: gouache, acrylic, and oil paint. Our choice to use propylene as is not fabricated out of thin air, but determined on demand.

First of all, consider cleaning, friends who have learned to paint know that no matter how long the gouache is painted, as long as you wet it with water, it will still fall, that is to say, if we paint the wall with gouache, it will not be able to clean the wall. And then we have to consider the cost and the amount of work, we all know that oil painting dries very slowly, and the same amount of oil paint is 2 or 3 times higher than acrylic, so it is not suitable for the most wall painting paint. Acrylic, on the other hand, combines the advantages of gouache and oil paint, which dries relatively quickly and is waterproof.

Feature 1: It dries quickly, compared to oil paintings, which take several months to dry. The propylene only takes a few minutes to dry, which greatly saves us time in painting.

Feature 2: Waterproof, acrylic is different from gouache pigment. After it dries, it will form a layer of gum on the surface of the wall, similar to the kind of rubber material, which cannot be washed off with water, so there is no need to worry about the wall not being wiped with water.

Feature 3: The color is full and vivid. When using, no matter how we mix the color, it will not make the pigment dirty or gray.

Feature 4: The preservation time of the work is long, and the oil painting will be slowly oxidized, hardened, cracked, etc. Gouache paintings will fade over time, and within a few years we will find that there is basically nothing to see.

But acrylic painting is different, it will form a layer of adhesive film after drying, this layer of adhesive film is similar to plastic, and can be stored for a long, long time.

Summary:The above is all the content of the wall painting material acrylic introduced to you, in general, acrylic is not only a very good painting pigment, but also has the excellent characteristics of environmental protection, non-toxic and resistant to preservation, which is the best choice for us to do wall painting. I hope the article edited by Little Hunger Socks can help everyone.

OK. Acrylic pigment is a new type of painting pigment mixed with a chemically synthesized latex (containing acrylate, methacrylate, acrylic acid, methacrylic acid, as well as thickener, filler, etc.) and color particles, which belongs to synthetic polymeric pigments.

Acrylic paint, invented in the 50s of the 20th century, is made of pigment powder and acrylic latex, which can be used for the painting of hand-painted wall paintings, as well as other decorative paintings. Acrylic paint is soluble in water, and can be easily dissolved in oil painting, which is a very good hand-painted pigment.

Acrylic pigment belongs to synthetic polymeric pigments, invented in the 50s of the 20th century, is made of pigment powder and acrylic latex. Acrylic latex is also known as acrylic resin polymerized latex. There are many types of acrylic resins, such as methacrylic resins, etc., therefore, there are many types of acrylic paints.

Foreign pigment manufacturers have produced acrylic series products, such as matte acrylic paints, semi-matte acrylic paints and glossy acrylic paints, as well as acrylic matt oils, varnishes, plastic ointments and so on. It can be used for the painting of hand-painted wall paintings, as well as other decorative paintings, acrylic paint is soluble in water, and can be easily dissolved in oil painting, it is a very good hand-painted pigment.

Acrylic painting should be painted on a base made of acrylic base (gesso) and not on an oily base. Material experts also do not advocate the mixing of acrylic with oil paint, especially not to paint oil on acrylic base, mainly for the permanent preservation of the work. There is no adverse reaction between acrylic and oil paint, and its adhesion when used alternately is subject to the test of time.

When painting a wall painting with acrylic, the acrylic is mixed with water.

Painting a wall with acrylic paint has the following benefits:

1. Non-toxic and formaldehyde-free: acrylic pigment is a water-based blended pigment, without formaldehyde and other toxic volatile substances, which is harmless to the human body;

2. Strong dilution: acrylic pigment can be mixed with water, and the thickness can be adjusted according to needs;

3. Strong expressiveness: acrylic pigments are bright in color and high in saturation;

4. Fast drying and waterproof: acrylic pigment is only soluble in water once, and it is no longer soluble in water after drying, so the picture is kept for a longer time, and the wall can be taken care of at ordinary times.
