How to paint the cement wall, what paint to paint the cement wall directly

Latex paint process.

1. Main construction technology.

Sweep the base layer Fill putty, scrape putty locally, grind the first full scraping putty, grind the second full scraping putty, grind the second full scraping putty, grind the sealing primer Brush the first coat of paint Fill the putty, grind the second coat of paint Polishing and working.

2 Construction points.

Base treatment is the key link to ensure the quality of construction, in which to ensure that the wall is completely dry is the most basic condition, generally should be placed for more than 10 days. The wall must be flat, and the putty should be scraped at least twice to meet the standard requirements.

The construction method of latex paint painting can be hand brushing, roller coating and spraying. When brushing, it should be operated continuously and quickly, and it should be brushed at one time.

When painting latex paint, it should be uniform, and there should be no missing brushing and flowing adhesion. Brush it and polish it. Generally, it should be done more than twice.

3 Precautions.

1) The putty should be matched with the performance of the coating, solid and firm, and should not be powdered, peeled and cracked. Use water-resistant putty in wet places such as toilets.

2) The coating solution should be fully stirred, the viscosity is too large, and the thickener can be added if the viscosity is small.

3) The construction temperature is higher than 10 degrees Celsius. There must not be a lot of dust in the room. It is best to avoid rainy days.

The master in front of him went home to the construction process in the book, but it should be added that many cement walls will be alkaline, for the sake of insurance, it is best to pickle first, that is, spray the wall with 3% oxalic acid, and then paint the wall after drying. In this way, quality can be ensured.

First, texture paint can be used, but it is very expensive!

Second, maybe 888 seasoning brush a layer, and then use liquid wallpaper! Affordable and cost-effective.

What kind of paint is directly painted on the cement wall! Hello, I am glad to answer for you<> pro-cement wall direct painting is as follows: cement wall can not be directly painted exterior wall paint, because before painting exterior wall paint, it is necessary to keep the cement wall in a flat state, the surface can not appear potholes, and the surface can not exist floating ash, otherwise it is likely to fall off.

2.In addition, if you directly brush the exterior wall paint on the cement wall, then after a period of time, the wall solution will be alkaline, because the cement itself is alkaline, so from the appearance, it will affect the overall effect. Therefore, when constructing on the cement wall, it is also necessary to operate according to the actual situation, and to apply latex paint in the correct way.

The first is the need to check whether the walls meet the conditions for construction. For example, the moisture on the surface of the wall should be less than 6%, and the pH value should not be greater than 9. In addition, if the wall is soaked by slag, oil stains, dust, etc., it needs to be cleaned in advance, so as not to bring greater obstacles to the construction and affect the overall effect.

In the process of applying latex paint, it is necessary to try not to let the paint exceed the painted area, so you can use a professional ruler or cardboard. And the latex paint is to be painted 2 3 times, each construction needs to wait until the previous latex paint is completely dry, so as not to affect the effect of the later painting, bring the trouble that does not have to collapse the ridge, I hope mine can help you <>

Do you have any other questions?

Hello, the following types of paint can be used for direct brushing:1Latex paint:

Paints are more durable than latex paints, but they require the use of a thinner and a cleaner. When using, it is necessary to pay attention to the use of a well-ventilated environment to avoid harm to the human body. 3.

Gypsum paint: Gypsum paint is a special coating for cement walls, which has good adhesion, water resistance and alkali resistance, and is more suitable for the use of cement walls than traditional latex paints and paints. 4.

Environmental protection paint: environmental protection paint is a more popular paint material in recent years, which does not contain harmful chemicals, is safe and environmentally friendly, and also has the advantages of good coverage and easy construction. In short, before choosing a coating, you need to choose the right paint type according to the actual situation and your own needs, and pay attention to the use environment, ventilation, protection and other issues to ensure the quality and safety of construction.

3. Cement wall painting method.

The construction method of painting can also be hand brush, roller coating and spraying, and the painting method should be continuous and fast, and the brush should be completed at one time. The loss of the hand brush to the material is relatively less, and the quality can also be guaranteed, but compared to its longer construction period, it can be combined with roller coating, and the roll coating can be used in a large area, and the corner collapse part can be used with a hand brush. In this way, it is very practical to improve efficiency and ensure quality.

4. When brushing, it should be uniform, and there should be no missing brushing, flow attachment and other phenomena, generally speaking, it needs to be brushed and polished once, and it needs to be more than twice.

Summary: The relevant content on how to paint the cement wall is introduced here, and the painting on the cement wall must follow the steps, and some details in the process of painting should be paid attention to.

For the cement wall painting, the wall base must be treated, and the construction of the paint must be carried out after leveling with putty, so as to ensure the stability of the paint use.

For walls with color requirements, the area should be accurately calculated in advance, and the materials used should be evenly mixed at one time. Then there is the primer, which can prevent the wall from backing up moisture, make the color of the topcoat even, and prevent the water stain lines caused by wood acid on the board.

When the wall paint is dry, sandpaper the wall is sanded to reduce the wall brush marks and make the wall smoother. When sanding, pay attention to feel the smoothness of the wall with your hands from time to time, so as to judge the need for sanding. It should be noted that when sanding, try to use finer sandpaper, and thoroughly clean the wall after sanding.

One: Priming.

Imitation cement paint is generally made on the wall with a relatively large area, so the base layer still needs to be treated, but due to the characteristics of the anti-cement paint itself, the requirements for the base layer are not particularly high, as long as the putty is batched, the anti-alkali primer can be done, the putty is directly flat, and the anti-alkali primer is directly sprayed all over the wall.

2: Batch imitation cement paint main material.

After the base layer is treated, the main material of imitation cement paint is scraped directly on the wall with a batch knife, and the batch scraping method is basically similar to the batch scraping putty, but if there is a texture requirement, it should be based on the different textures, and the batch scraping strength is not the same.

Three: do a good job of protectant.

After the main material of imitation cement paint is dry, spraying a layer of protective paint on the surface can increase the feel, protect the cement paint itself and increase the brightness of the appearance!

Cement walls cannot be painted directly.

Because the cement wall is uneven and easy to contain dirt such as floating ash, direct painting will not only cause potholes on the wall, but also easily lead to falling off. And the cement is alkaline, directly on the wall paint, it is easy to cause alkali flowers for a long time. The cement mortar used in the plastering project has a large sand particle size, and the appearance is rough after plastering.

Precautions for wall construction.

1. If the renovation operation is done on the gray wall, the lime on the surface should be completely dried before it can be carried out, so as to ensure the effect of the entire wall, and there will be no spots on the surface, which will affect the future living life.

2. When the lime mortar is constructed on the wall, the lime mortar should be stirred all the time, so as to avoid the problem of lime mortar precipitation, destroy the effect of the final painting, and if the mixing is uneven, it will cause the wall to be particularly different shades.

3. When painting, you should ensure that you paint from the top to the bottom, or from left to right, no matter what painting method is used, you should ensure that there will be no mistakes and repetitions, so as not to have too much color difference.
