What is the process of painting latex paint on the wall of a new house decoration? The wall was pain

The process of wall treatment for the decoration of new houses:

1. Checking whether the wall is solid and flat is a step in the house inspection. To see if the wall is strong, the simple inspection method is as follows: find a hard object (such as a key, screwdriver, etc.), and draw a line on the wall to see if it is slag.

There is no shortcut to finding cracks and holes, only care + patience.

2 "Leveling" is a very important job, and it is also the basic purpose of decoration. The local wall flatness of some residential areas is very poor, then it is necessary to use gypsum to do a separate leveling, generally speaking, when the wall flatness is greater than plus or minus 8mm, the separate leveling is required to be charged separately, if it does not reach this extent, it should be included in the normal wall construction cost.

3 There will be dust when handling the wall, and it is inevitable that putty, paint or other glue will drip off, so be sure to do a good job of protecting the finished decoration products in the room in advance.

4 Scraping putty Preparation before plastering. Ensure that the wall is solid and flat, clean the wall with a steel brush or other tools, and make the cement wall as free of floating soil and floating and sinking as possible. Roll the concrete interface agent on the wall (individual walls may need to be patched), try to be even, and after it dries (generally more than 2 hours), you can scrape putty plaster.

Scrape putty (please choose water-resistant putty). The flatness of the wall should be measured before scraping putty (with a detection ruler of more than 2m) to determine the method of scraping putty. Generally, the wall can be scraped with putty twice, which can not only level but also cover the background color.

Putty with poor flatness needs to be scraped several times locally. If the flatness is very poor or the wall is heavily tilted, you can consider scraping the leveling plaster first for leveling, and then scraping the putty. The interval between each batch of putty scraping should be more than 2 hours (after the surface is dry).

For the decoration of new houses, the process of painting latex paint on the wall is 3 bottoms and 2 sides, first shovel the surface layer made by the developer, first do the bottom 3 times, and then do 2 times the surface paint.

This ah, there are two kinds of interior walls in the current community, one is scraped with putty, and the other is plaster (also called bottom plaster), relatively speaking, I think the latter is better! Because the putty of the former is very poorly scraped and not leveled, generally they buy such a community and have to be leveled and scraped from the new, and the adhesion is not high, and some have to brush 107 glue! The latter is much better, because the bottom gypsum has a large sand content, is scraped thickly, and is easy to level, and the adhesion with putty is large, and it will not fall off!

After putty on both sides, use sandpaper to smooth the stubble, and the texture can be painted on the wall!

It must have been used before whitewashing!

To brush latex paint, you should first scrape the putty and then brush it, and the putty can be scraped once.

1.Process flow:

Clean the wall, repair the wall, scrape putty, brush the first latex paint, brush the second latex paint, brush the third latex paint.

2.Clean the walls:

Remove the peeling and loose parts of the wall, and repair it with cement mortar, shovel the residual ash clean, and then sweep the wall clean.

3.Repair the wall:

Use plaster to level the bumps and potholes and gaps on the wall, and then grind off the sandpaper protrusions after drying to sweep away the floating dust.

4.Scraping putty:

The number of times of scraping putty can be determined by the flatness of the wall, generally three times, polyvinyl acetate emulsion for kitchen, toilet and bathroom: cement: water = 1:

5:1 water-resistant putty. The first time with a rubber scraper transverse full scrape, a scraper followed by a scraper, the joint shall not be left behind, each scraper at the end of the end to be clean and neat.

After drying, sandpaper, polish the floating putty and stains, and then clean the wall. The second time with a rubber scraper vertical full scrape, the materials and methods used are the same as the first putty, after drying, the sandpaper is smoothed and cleaned. The third time use a rubber scraper to find the putty or scrape the putty with a steel scraper, scrape the wall flat, and then smooth and polish it with fine sandpaper after drying, and the putty shall not be omitted or worn through.

5.Brush the latex paint for the first time:

The painting sequence is to paint the top plate first and then the wall, and the wall is up and then down. Clean the wall first, and use a cloth to wipe off the dust on the wall. The latex paint is painted with a pen, and when you use a new pen, remove the floating hairs and unstable hairs on the pen.

Latex paint should be stirred evenly before use, and diluted with water appropriately to prevent the paint from not opening all over the head. After drying, the putty is replenished, and then dried and polished with sandpaper and cleaned.

6.Brush the latex paint a second time:

The operation requirements are the same as the first time, fully stir before use, if it is not very thick, it is not appropriate to add water to prevent penetration. After the paint film is dried, use fine sandpaper to polish off the small bumps on the wall and the brush bristles, and clean them after grinding them smooth.

7.Brush the latex paint for the third time:

The method is the same as the second latex paint. Due to the rapid drying of the latex paint film, it should be operated continuously and quickly, starting from one end and gradually brushing to the other end, and the upper and lower brushes should be connected with each other, and the latter row of pens should be followed by the previous row of pens to avoid the appearance of dry rear joints.

When decorating the interior decoration, a very important thing is the wall decoration project, in which the painting of the wall is an indispensable step, the whitening of the wall not only makes the wall more beautiful, but also has a certain moisture-proof pants hole effect. So what are the steps to whiten the wall?

To do it well, you need to prepare materials in advance, such as cement mortar, putty powder, interface agent, latex paint and wall painting tools. These materials can be selected in moderate**, but you need to pay attention to their environmental performance, and you also need to check their production date when buying latex paint. Generally, the shelf life of latex paint is about one year, if it expires, the effect is not very good, and the quality of the wall will be damaged.

After the material is ready, the base layer of the wall needs to be leveled, the plane of the wall surface is repaired with cement mortar, and then the obvious protrusions are leveled so that the entire wall surface is leveled. This process is very important and involves the quality and aesthetics of the entire wall.

After the walls are leveled, the putty powder can be diluted and evenly stirred. The dilution of putty powder should be moderate. Then scrape the putty evenly against the wall. When the putty powder is not too thick, try to keep the water on the wall flat. Uneven areas need to be leveled again.

After waiting for the wall putty to dry, you need to sandpaper the wall to make the wall smooth and flat. When the wall is smooth and flat, if the wall is uneven, it needs to be repaired in time, and then the wall surface is polished. After sanding the wall with sandpaper, you can use a large tile bulb to level it.

Once the wall is smooth and flat, you can use roller emulsion paint to spray the white wall, or use special equipment to spray the wall. Regardless of the method used to paint the white wall, you need to pay attention to the thickness of the paint layer. In general, the thinner the better, and it is only necessary to coat the wall evenly.

This will reduce the cost of painting.

Overall,Wall whitening processThe most important step is to make the wall level, and the owner should pay extra attention.

1. The wall is painted with latex paint and must do a good job of treating the grassroots, if it is a rough house, check whether the cement wall is solid and smooth. If it is uneven, it needs to be re-plastered, the cement mortar is prepared, and the wall is leveled after being evenly mixed according to the proportion. 2. After the leveling layer is processed, it is also necessary to brush off all the floating dust on the surface of the wall.

After the surface is dry, brush the wall solid, because through the closure of the wall solid, it can bring waterproof, and can prevent the problem of alkali caused by scraping putty in the later stage, so after brushing the wall solid material, wait until it is dry and then scrape the putty.

Related information: 1. To brush latex paint after the most Chang sedan car presents a better effect, it is best to brush the primer before brushing latex paint, the main purpose of this is to prevent the problem of alkali return on the wall, and there will be no white powder on the surface in the later stage. And another effect of brushing the primer is to save latex paint, according to research, there may be a 20% saving between brushing and not brushing.

2. When brushing latex paint, you can use spraying or manual brushing. If you spray it, the surface molding effect will be better, there will be no brush marks, and the efficiency will be higher, but it may be more laborious than the absolute knowledge.

Generally, it is divided into base surface treatment--batch wall--sanding-batch wall--sanding-primer-topcoat.

1) The base surface treatment is mainly to see whether the powder layer is hollow, if it is an old house, try to remove the original powder layer, and then use glue to make a base, and then implement the batch wall.

2) Wall paint is a water-based solution, compared to the paint its toxic and harmful components are much less, so as long as it is produced by a regular factory, there is no problem, ** depends on your economic strength, the general salary can buy low-end (high-end is to spend concept money).

3) In fact, the most important thing to pay attention to is the batch of wall putty powder and blending glue. At present, ordinary putty powder (about 15 packs in the building materials market) has been eliminated, and water-resistant putty powder is basically used, and the glue used to mix putty powder is precisely the first of toxic gas.

I am not a professional, but I have renovated my own house a lot, and I have summed up my experience. I hope it will help you, and I hope you can forgive me if I say something wrong. Finally, I wish you a happy decorating!

Standard construction: scrape putty powder, light sanding, brush the primer once, brush the topcoat twice.

There is nothing to pay attention to when scraping putty and grinding. The master did the same. There are no such thing as cutting corners.

Pay attention to the painting.

You buy the lacquer. The specialty store will give you the standard dosage. But painters in the Chinese market.

The vast majority have no expertise. The standard is about 15% with water. Generally, masters like to mix more than 50% with water.

The one that paints the wall is less paint and more water.Even if the brush is 1 bottom 2 sides. The number of passes.

However, the paint film did not reach the required thickness. There will be a few more barrels of paint left for you. Or.

No one noticed. Pour the lacquer into the toilet bowl (the owner buys the lacquer for the master to use.) This is the case in about 40% of construction sites).

So paint. One is going to see it. Second, communicate well with the master! Finish the paint.

Shovel the wall skin and put putty on it and scrape it white.

1. Tidy up the original wall.

Usually, the original wall will have oil stains, floating ash, hollow drums or cracks, and the water absorption is a low level of doubt, so you need to do some finishing work on the wall. But considering that it is a new home, there is no need to worry too much about these issues. Just remove the ash with water and keep it dry.

2. Scrape putty.

It is better to choose putty with higher particle fineness and harder texture, and you can also add a certain amount of white latex to the putty, which can improve the hardness of the putty.

3. Grinding. Try to use finer sandpaper, usually softer putty with 400-500 sandpaper, harder texture with 360-400 is better, if the sandpaper is too thick will leave a deep sand mark, painting is not able to cover up.

4. Apply primer.

If the wall eats a large amount of paint, it is best to add a little more water to the primer to ensure that it can be painted evenly. Don't think that just because it's a primer, it's okay to use a poor roller, the brushing effect of the primer will directly affect the effect of the topcoat, and you should use a roller with the same texture as the topcoat.

5. Topcoat. The appropriate painting here is the ordinary painting operation, do not add excessive water, it will affect the thickness of the paint film, the feel and the hardness of the paint film, try to choose a better thing, the hair of the drum is not too short, but it must be relatively fine, so that the paint film will feel delicate, and the first thing to pay attention to is the corner of the wall, the stubble part of the center of each roll and the direction of the paint.

6. Maintenance. The latex paint will generally dry after 4 hours after painting, but the dry paint film has not yet reached a certain hardness, which requires simple care, and there should be no wiping or any touching of the wall within 7-10 days.

First, the quality requirements should be flat, and the second should be light, and there should be no capillaries.

The test method can be observed from the four corners of the wall with a light bulb, and it is clear whether the brush is smooth or not. After the putty is batched, it is completely dry. before applying it a second time.

Apply the wall primer that goes with the latex paint you purchase, then apply the topcoat. Both the primer and topcoat can be slightly thinner according to the product instructions to avoid brush marks. But it can't be too thin.

Generally, it is 10%-30%. Excessive dilution will lead to poor film formation, and its texture, scrub resistance, and durability will be damaged to varying degrees.

2. If there is paint construction at the same time, it should be done after the base layer of the wall is treated, and then the latex paint will be painted after the paint is completed, so as to avoid the emulsion paint being yellowed due to the toluene volatilized by the paint, causing unnecessary losses.

3. Surface treatment:

New surface——— new concrete or plastering usually contain high moisture, the wall must go through sufficient drying time, if the drying time is short, high moisture content will lead to latex paint blistering, discoloration, alkali, peeling and other paint diseases. Generally, the plastering wall is dried for at least two days.

Fourth, the choice of advanced construction technology: the construction can be used brushing, roller coating and spraying process, no matter which of the above methods can achieve the desired effect, but the viscosity of the latex paint needs to be adjusted, the viscosity is easy to paint during construction, and there is no obvious brush mark after brushing. If the viscosity is too large, the brush marks are obvious, and the viscosity is low, which is easy to cause slag flow and poor hiding power.

5. It should be noted that the construction should not be carried out under the condition that the wall surface temperature is lower than 5 degrees Celsius.

Sixth, the color paint should be stirred evenly, especially when using brightly colored products, if not stirred evenly, when the paint in the color paste is dispersed unstable or due to long-term storage after the color paste precipitation, then the construction will cause the finish to bloom, seriously affecting the decorative effect.
