What are the requirements for painting directly with acrylic on a cement wall?

No, because its flatness does not meet the requirements of direct painting. If the floor is to be painted, it must be retreated with a higher grade of cement, leveled (usually by self-leveling technology) and smoothed to give it a smooth and flat surface. After drying, it can be painted with a floor paint designed for the floor.

Halo is a hand-painted wall, right, when we paint, we use Bing Xi directly, do not add things inside, in fact, do not brush the varnish on the exterior wall, after a long time, there will be a small crack on the varnish is ugly, if you want to brush it, you can also do it but in moderation.

1. Paint on the tempered paint, and test the water resistance of the tempered coating.

2 Wipe the wall with a damp towel a few times, preferably without shedding the powder.

3 If you depowder, just apply another layer of matte acrylic paint.

Let's spray it with fixing liquid of a large bottle.

Painting directly with acrylic on a cement wall, you need to pay attention to:

1. The color painting is thicker and heavier, because the pigment adhesion of the cement wall is poorer.

2. The edge part of the picture must be outlined, which will make the picture more exquisite.

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).

I'm going to paint in acrylic on the exterior wall, and the picture on the wall is can I paint the exterior paint directly in acrylic?

Hello, it's totally possible. Acrylic paint is generally used for exterior wall painting and indoor painting, but the difference is that outdoor wall painting has to be eroded by natural weather such as wind, sun and rain, and the maintenance time is shorter. Several properties of acrylic paint make it a good choice for wall painting

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 the saturation is slippery and high; Attention should be paid to outdoor wall painting: one pats is the thickness of the paint to be painted, and the other is to make up the color or repaint when the paint is eroded.

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.

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.

In principle, there is no requirement for wall painting, whether it is a wall as smooth as a mirror or as rough as a stone, you can paint a wall painting.

But in order to achieve a good effect, the wall painting is generally painted on the wall with latex paint, so the wall should be flat, not too smooth or rough, and not dusty.

Wall Painting Steps:

1.wall treatment.

The base treatment of the wall is more important, and it is generally painted on the wall with latex paint, so the leveling of the wall, the primer, and the pattern planning should be prepared in advance.

2.Prime.

People who do not have art skills should draw the sketch on the wall, gently outline the draft with a pen, and color it only after they are satisfied, otherwise it is not easy to modify.

3.with paint.

Buy pigments against the effect of the pattern, if you can't grasp the effect of latex paint toning when you buy, don't rush to make a decision in the paint shop, you can take home the color swatch or paint sample, and observe the paint color in natural light and night light. High-gloss paint will make the room look brighter, but it is also easy to highlight the shortcomings of the wall, if the wall is not too flat, it is recommended to use flat paint. The paint must not be too thin, otherwise it is easy to leave flow marks on the wall.

Acrylic paints can be mixed according to needs, and the pen is done carefully.

4.Ready to color.

First, cover the walls where you want to graffiti with newspaper so as not to stain the ground. When hand-drawing a simple pattern, first draw the outline on thin, absorbent paper, then cut it out, place it on the wall, and color it by rubbing. If you are afraid of damaging the wall, the most convenient way is to take the spray sticker, carve the picture after spraying, and paste it on the wall with the sticker.

If you find a mistake in acrylic paint, you can wipe it off with a damp rag and repaint, but you can't use this method for latex paint.

5.Maintenance. After painting, ventilate and wait until the wall is dry before touching it. Although acrylic paint is waterproof and scratch resistant after drying, it should not be scrubbed vigorously with water.

It is not very good to use acrylic as a base, first, the cost is too high, and second, it is difficult to draw a pattern on it after acrylic priming, (if you have used acrylic, you will know the characteristics of acrylic, which will form a waterproof film after drying, which is too smooth!) If you want to make a base, you can use latex paint toner.

In fact, there is no requirement for general wall paint and latex paint can be as long as the fingers touch it without white ash If it is done outdoors, if it is a cement wall, it is best to scrape a layer of paint After painting, spray a layer of varnish to protect it, and then use it indoors, it is best to do it in one go, and the coloring is generous.

If the painting is not large, sandpaper is sanded, and after flattening, it is evenly painted with wall paint and dried, and then start pasting. If the area is too large, then scrape the putty once and then scrape it again (according to the flatness) after it cools and dries, and then flatten it with sandpaper before painting. Be sure to dry it, otherwise the wallpaper will be fluffy later!

Generally, the wall paint is used as the base, and the acrylic and putty wall are not integrated.

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.
