How to paint the wall with white plaster without dusting? How can the white plaster paint wall not f

Painting the walls with white plaster, if you want not to fall off, stucco paint is the key.

First, when using white ash to paint the wall, you can properly mix some glue in the white ash, so that the white ash after mixing the glue is used to paint the wall, and the overall effect is very good, and there will be no ash.

Second, first use white plaster to paint the wall once, and then apply latex paint again.

This can also be prevented. The white ash wall has fallen ash, and it can beautify the wall and make the wall more uniform.

Third, first brush the white ash wall, and then brush the industrial glue, which can play the role of sealing the white ash and prevent the surface from falling ash.

Through the above methods, the white ash brush wall will not fall ash, and the operation method is very simple, and it can generally be constructed and operated.

There are three main reasons for peeling, one is that the room is damp; First, the original base foundation construction is not firm; There is also a kind of construction process is wrong, not in strict accordance with the process and specification operation, resulting in wall paint peeling.

Wall peeling treatment method: you need to remove the part to the cement layer, brush the interface agent, and then scrape the wall lining or waterproof putty 2-3 times, and then brush the primer, but also pay attention to the construction below the moisture content (10%), to avoid high humidity (85%), low temperature (+5) environment construction.

Soak the white ash in advance. This is the key of the keys. It's not about salt.

Okay, let's talk about chemistry. 1. Stone (limestone caCO3) is burned with fire to obtain white ash (also known as quicklime cao). The white ash is fully soaked in water to obtain lime paste (also known as hydrated lime Ca(OH)2), and this lime paste has viscosity.

When painting the wall with lime plaster, stir it in the water again to stir up the precipitated lime plaster. The lime plaster is brushed onto the wall and reacts with the carbon dioxide in the air for several days. It becomes a limestone caco3 that is as hard as a stone.

In the past, when I painted the wall, I was always misled to add salt. In fact, after soaking for half a day, it will stick. Please like.

After the white ash of your pond is dried and solidified, spray a house of transparent waterproof repair agent, which does not change its original color, is not easy to mold, and does not fall ash

White ash mixed with glue and salt does not fall ash!

The paint does not come off.

The white ash is all gone.

Paint the walls with high-quality lime water, close the doors and windows before the coating dries, bring the brazier or coal stove indoors, and open the doors and windows after baking for an hour. In this way, the stone gray color is white and will not fall off after the coating dries.

Buy 108 glue from the store that sells decorative materials, more than ten yuan a bag, generally 5 kilograms, very cheap.

In the case that the viscosity of putty powder is not enough, it is necessary to add emulsion or 108 glue to enhance adhesion.

Lime water brushing the wall does not need to be mixed with glue! Only when putty powder is used, when the viscosity is not enough, you need to add emulsion or 801 glue to enhance adhesion!

The wall is dusty, and the wallpaper cannot be directly pasted on this basis.

Treatment method: 1. Further check the treatment layer of the wall to see if there is a problem of hollow drum delamination and poor surface curing strength, if there are the above problems, the problematic part needs to be removed; If you don't have any of the above problems, you can start with step 4.

2. After removing the problematic part, scrape the plaster and putty on the wall again for leveling;

3. After the putty layer of the wall is dry, the surface is polished;

4. For the polished and smooth wall, clean the floating dust on the surface and apply the interface agent, and then pave the wallpaper.

1. Prepare the drum as soon as it comes.

Put (the painter rolls the paint on his own seed), roll it up with water, several times in a row, you can easily remove the white ash.

2. If you really can't get wrapped, you can also choose to paste the tiles, as shown in the figure 3. If it is the white ash scraped on the cement wall, take a shovel to shovel off and brush the glue, and then redo it with waterproof materials, preferably with exterior wall paint.

4. You can use a nylon brush or an iron brush to brush it off, and after a few days of observation, it is determined that there is no longer white powder precipitation, and the cement wall can be painted after drying and grinding.

5. If there is a lot of white powder on the surface of the cement wall and it continues to precipitate, after cleaning it, you can first apply a wall primer to prevent salt erosion and the formation of wall cancer in the future, and be careful not to use oil-based paint or impermeable wallpaper to paint or decorate within three months.

"White ash" is the putty layer, which can be moistened with water, and then removed with a batch ash knife.

Method Steps:1Use a roller for brushing paint.

2.After it is soaked in water, it is rolled up and down the wall like a roller paint.

3.After the water penetrates into the putty layer, it can be gently removed with a batch ash knife.

The simplest and most direct is to paint the wall, which is smooth and bright and anti-dirty, and it is clean with a dish soap rag when it is dirty.

You can use vinegar, or you can use hydrochloric acid. A chemical reaction occurs, and the lime melts off.

How to recover the lime on the wall.

Removal 1, can be made artificial physical removal, such as choosing a shovel, and then shoveling off, or adding a wire to scrape off.

2. Because the composition of lime is calcium carbonate, then we can use vinegar to eliminate it, and cover it with lime.

3. Both physical and chemical methods are acceptable, but they must not hurt the wall;

1. Buy a rolling bucket, use the bucket to roll water on the wall, buy a shovel blade, and drop it 2.

Just use a shovel to shovel.

3. Your family should be a relocated household, the white paint can not be washed up with a hose, and the room that is finally dried can not wait for the renovation to be renovated soon, and the latex paint is not good for the future! You just wet the wall with a roller and scrape it off with a shovel! If you are troublesome, find a professional person to scrape, and it is not expensive.

4. As long as the white ash on the wall is not powdered, the shovel can not be shoveled, and it can be ignored, when the time comes, the decoration is leveled with gypsum, and the putty is applied to the latex paint, otherwise if you use water, you will want to brush the wall paint as mentioned above, and you are afraid of dampness. When I want to shovel the home decoration I make, the blistering sand and ash will fall off.

Leave the rest alone.

There are many places where it will be used in renovationWhite cement, for example, the screeching of the wall foundation, the treatment of tile trenches. But many people will find in actual operation that some white cement will fall white ash, so how to make white cement not fall ash?

Properties of white cement.

White cement is also calledWhite Portland cementIt is a kind of cement, which is a kind of high-grade cement, which is often used for architectural decoration.

The white cement has a high grade, but the hardness is not strong, the solidification time is short, and it must be mixed with other materials to exert its effect, and cannot be used aloneUse.

The reason for the ash of white cement.

1: The white cement is too dry or too thin.

That is, when the white cement is mixed, the water is too small, the powder is too dry, and it is not completely dissolved. Or the white cement is added too much water, resulting in the white cement is not solidified.

2: White cement does not match other additives.

Many people will add some other materials, such as putty powder, when using white cement.

Double flying powder, talc.

This is not much of a problem in itself, but the material formulas produced by different manufacturers are somewhat poor.

Here I will talk about the phenomenon I have encountered, the same is the interior wall putty powder, two manufacturers, one is no problem mixed with white cement, the other is not, after drying, it is all white powder when touched by hand.

3: White cement fails.

White cement is the same as cement, it is powdery, easy to absorb water and moisture, once wet, it is easy to fail, so the storage time should not be too long when buying white cement, that is, it is best to buy and use.

How to make white cement so that it will not fall powder.

1: As mentioned above, white cement belongs to high-grade cement, which solidifies quickly. Water that is too dry or too thin can cause powder to fall off, crack easily, and not have high firmness.

So in useWhen white cement is used as a decoration material, in order to alleviate its solidification time and enhance its firmness, it is not recommended to mix it with water, but it is recommended to use it801 glueWhen used together with white cement, this can not only delay the setting time of white cement, but also enhance the strength of white cement.

2: In addition to stirring with glue, for:To give full play to the maximum effect of cement, in the process of mixing white cement, add an appropriate amount of white sand, which is a special sand and is very delicate. Cement + sand is the best partner, and white cement is no exception.

Precautions for the use of white cement.

As mentioned above, white cement is mainly used for surface decoration of materials, but it is incorrect to use it as the main decoration material for walls, after all, its hardness is not strong, and it is easy to have problems.

Now the putty powder technology is very mature, as far as the decorative wall is concerned, the performance is better than white cement in all aspects, so I personally recommend that the wall decoration try to choose putty powder.

The white cement ash can only be scraped, and the appropriate putty powder can be selected to scrape the wall, and the white cement surface can not be scraped again, because this will lead to the subsequent batch scraping of the material peeling and falling off.

Conclusion. The above is my analysis of why white cement will lose powder, and I have shared a little experience on how to operate to avoid white cement. Personally, I think that white cement cannot be used as the main material for decorating the wall, so I should choose putty powder to scrape the wall as much as possible

The white ash should be properly mixed with some glue, and the wall will not fall ash. Paint the wall with white plaster first, and then apply latex paint again, which can also prevent it.

Remove some local peeling places, and then brush the primer once, ensuring that the moisture content is less than 10%, not in high humidity and low temperature environment.

Choose the best white cement, the best white cement has a good adhesion, and it will not fall off after brushing.

1. When mixing the coating, you can add some glue to it, so that the adhesion is better, and it is not easy to fall off.

2. Before painting, you can brush the white ash and then the latex paint, which can also prevent the paint from falling off and make the wall paint more evenly.

3. In addition, you can brush the white ash first, and then brush the industrial glue, which also has the effect of sealing.
