Can black cement walls be painted directly with latex paint?

No. Cement walls cannot be painted with latex paint directly.

To have the conditions of latex paint, to meet a few points:

First, the peeling, pulverizing, hollowing parts should be removed, small potholes, and repaired and leveled.

Second, the construction wall must be strong, smooth, free of oil, floating ash and other dirt.

3. Putty powder per kilogram.

Add about kilograms of water, stir the powder with water to form a paste (there can be no undecomposed dry dough in the slurry), put it for 5 minutes, and then stir it again. Electric agitation works best.

Although directly brushing latex paint will cause the surface of the wall to be uneven, it is possible to brush latex paint directly on the black cement wall without scraping putty, but there are many processes and steps that need to be paid attention to, we need to use corundum gauze to polish the cement wall, remove the sand particles attached to the surface, clean the wall to remove dust and sand particles, and repair and level the gaps with gypsum powder and white glue. Paint the wall with white glue and water at a ratio of 3% or use a wall shovel to ensure that the wall skin will not fall off.

It's harder to cover the dark with a light color, but it's still okay. We need to brush latex paint several times, but the latex paint is too thick will cause a series of problems, when we choose latex paint, we should choose a latex paint with a stronger coverage rate, that is, the titanium dioxide content is a little higher, brush two to three times should be able to cover.

Cement walls cannot be painted directly with latex paint. The main component of the cement wall is cement mortar, which is alkaline, and if the paint is directly painted, it is easy to reverse alkali after use. At the same time, there are many uneven defects on the cement wall, and the surface will be attached to dust and other stains, and if the paint is directly painted, the wall will be uneven, which will affect the flatness and aesthetics of the wall, and there will be cracking, peeling and falling off of latex paint after use.

The cement wall can not be directly painted, because the construction wall is smooth, easy to contain floating ash and other dirty sections, direct painting will not only cause the wall to be potholes, but also easy to cause falling off. And the cement is alkaline, directly on the wall paint, and it is easy to cause alkali flowers after a long time.

If there is no shelling, hollowing, or cracks on the white cement wall, it can be removed without shoveling. On the cement stucco layer (whether black or white), the paint is applied after sanding. Brushing paint directly on white cement like you is cutting corners.

First of all, the procedure of wall treatment: first scrape putty, polish after the putty is dry, then scrape putty, polish, scrape putty, polish, polish, after drying, apply the first latex paint, and then brush the second latex paint after drying. Only after the wall is scraped flat will the latex paint be brushed to keep it flat.

Cement wall can not be directly coated with latex paint, to have the conditions of latex paint, the construction wall must be strong, smooth, no oil, floating ash and other dirt with peeling, pulverization, hollow part to remove, small potholes, and repair and smoothing. Add about kilograms of water to each kilogram of putty powder, stir the powder with water to evenly form a paste gel (there can be no undecomposed grip dry dough in the slurry), place it for 5 minutes, and then stir it again. Electric agitation works best.

Generally, it is scraped twice, and the first time requires full scraping of putty, flat wall, and no stubble. After the first time is dry, you can scrape, and the second time is slightly dry (not semi-dry), use an empty scraper to be parallel to the left and right, and evenly and forcefully calender several times to achieve a smooth and delicate effect. Generally, it is scraped twice, and the first time requires full scraping of putty, flat wall, and no stubble.

After drying, polish and sweep the ashes cleanly, and apply latex paint.

No, you need to wait for the cement wall to dry, which requires finding a professional decoration team to operate.

I really don't know, I haven't understood, and many people have big questions about this issue.

No. The cement wall can not be directly coated with latex paint, to have the conditions of latex paint, to be full of sail draft to check a few points:

1. The part of the eggplant that has peeling, pulverizing, and hollowing should be removed, small pits, and repaired and smoothed.

Second, the construction wall must be strong, smooth, free of oil, floating ash and other dirt.

3. Add about kilograms of water to each kilogram of putty powder, stir the powder with water to form a paste (there can be no undecomposed dry flour ball in the slurry), place it for 5 minutes, and then stir it again. Electric agitation works best.

1. The cement wall can not be directly brushed with latex paint, because it is likely to affect the use of latex paint, and it will also cause some damage to the wall, and the effect is very poor.

2. At the same time, it is very likely that the latex paint will be scrapped, which is very wasteful, so it is best to brush the latex paint on the wall after the corresponding treatment.

How to paint latex paint on cement walls?

1. First of all, you need to polish the cement wall, and after grinding and smoothing, you must remove the dust on it, and then scrape putty on the wall.

2. When scraping putty, it is necessary to mix the putty powder and water according to certain specifications, and it will become a paste after stirring evenly, and then it is necessary to scrape the putty evenly on the wall.

3. After scraping the first putty, wait for the first time to be completely dry before scraping the second time. When it is completely dry, it is time to paint the walls with latex paint.

In terms of surface effect, it is possible to directly focus on the topcoat on both sides of the cherry brush; However, from a quality point of view, there is a great hidden danger in the practice of directly brushing both sides of the topcoat without primer.

Considering economic factors, the cost of some primers is higher than the cost of topcoat, and the design requirements of the house may not be too high. For this reason, they are not willing to spend more on this primer. This idea is wrong, no matter how good the topcoat is, it cannot replace the primer.

Because the primer mainly plays the functions of sealing, alkali resistance, enhancing the adhesion of the topcoat, and saving a certain amount of topcoat, if the primer is not made, it is easy to wrinkle and bloom after a period of time, and may cause the paint film to dry too quickly and cause topcoat cracking and waste of topcoat.

<> "1. Can cement walls be painted directly with latex paint?

The cement wall can not be directly guessed with infiltration and brush latex paint, because if you operate in this way, the latex paint will not be able to be closely combined with the base layer, and the flatness of the wall will be very poor, which will lead to a lot of gaps in the middle. The cement wall has a high water absorption rate, which will cause the loss of water in the process of latex paint film formation, resulting in wrinkles, uneven color, and even cracking of the latex paint on the entire wall.

The uneven wall will also cause the amount of latex paint to become larger, at least 3 2 more materials, resulting in a significant increase in material costs and labor costs.

Second, latex paint construction precautions.

1. Color difference.

There is a certain color difference in latex paint, especially colored latex paint, try to choose the same batch of the same manufacturer when purchasing. And the local test should be done before painting, and the painting work should be carried out after the color is correct.

2. Ambient temperature.

During the painting process, there are certain requirements for temperature due to wall decorative coatings. The ambient temperature is 5-30 °C, and the air should not be humid. It is better to choose spring or autumn work, if the temperature is too high or too low, it will have a certain impact on the latex paint.

3. Dilution problem.

The latex paint itself is very heavy, if it is directly on the wall, the aesthetics will be affected by the old surplus, it should be diluted with water first, the light-colored latex paint is recommended to be diluted by 15%, and the dark-colored latex paint should not be diluted by more than 5%.

4. The primer is uniform.

Priming is a very important link, the bottom surface is done, the latex paint can be better integrated with the wall, and the whole spike spine effect is also better.

1. It is not recommended to quietly brush latex paint in the wall hall that has just completed the decoration, and it is best to batch a layer of putty to level it before painting.

2. After the hydropower renovation is completed, the wall is not so smooth after filling the slots. Moreover, the cement wall also has a certain amount of ups and downs, if you play with paint directly, it will lead to latex paint falling off and other phenomena. Moreover, cement also has a certain alkaline, and latex paint will be prone to alkali flowers.

3. Before painting the wall paint, after approving a layer of putty, the putty can make the wall more dense and smooth. When painting the wall paint, the wall paint is evenly brushed. It will not penetrate into the base layer, and it will also isolate the direct contact between the wall and the latex paint, and increase the firmness of the wall paint.

The rough red brick wall can be directly sprayed with latex paint. Ordinary people don't recommend that kind of interior decoration, which is very distinctive. Nowadays, everyone has to assemble the wall to make it shiny and clean before painting.

However, this kind of interior decoration is no problem, but it is generally not done in ordinary homes. And when we bought a house, some of the houses were already scraped with putty powder. So at this time, if we want to paint on the blank room, we have to get the putty powder off.

Paint directly in the rough room, not only will the wall be uneven, and in the long run, our own walls will also have problems, so these walls are all damp or have some problems, and our own walls are the easiest to crack. Immediately brush the paint brush, basically just can't see what effect, if you really want the effect is also very consuming paint, only brush many times to see the color on the wall, but people in the decoration generally brush one or two times on the line. Even if you brush it out like this, the wall is very uneven, and if you accidentally prop it up on the ground, it may also cause scratches.

It is best to use a better wall paint for such a thing, and we must ensure that the wall is intact before we paint, if there is any problem with some walls, we are likely to have a very big problem after painting. Of course, if it is a public place, such as a café or some studios, it is particularly beautiful to decorate like this, which can not only save the salary of the old ** repair, but also give everyone a practical effect of artwork, so it is not that this method is not feasible.

If you really want this effect, I personally think that it is to do this kind of house modeling, although it is an artificial false hair embryo, but in this way its service life will be greatly increased. Spraying latex paint on the wool is easy to damage the walls of the house in general. Careful consideration should be given when decorating, and it is a waste of time to repair it back and forth in the middle and later stages.

Everyone chooses according to their own personality, and some people just like this kind of interior decoration.

The cement wall cannot be directly painted with latex paint, because this is likely to affect the use of latex paint, and it will also cause some damage to the wall, and the effect is very poor.

It is not possible to apply latex paint directly. Use coarse sandpaper to sand and clean it, and you can apply latex paint. If the latex paint is colored, the latex paint should be stirred well.

That's definitely not possible, it's best to brush the cement first and then apply this, you need to pay attention, you must apply a little less, otherwise it will run down.

This is not possible, you have to make sure that the cement wall is covered with a protective film, and then brush the latex paint, which will be smoother.
