How to repaint lime walls??? How to paint the wall with white plaster without dusting?

Note that quicklime will boil the water after adding water, be careful of burns! It's best to go to someone else's house to get some ready-made hydrated lime, because you don't need much, and lime generally won't give you a few kilograms to sell.

If there are not many holes, add a small amount of water directly with hydrated lime, mix it into mud and stuff it into the hole, and scrape the surface flat. If there are many holes, you can fill them with coarse sand first, and then scrape the surface with lime plaster. Then add a small amount of water to the other hydrated lime (subject to the white wall after mixing), mix it into lime mortar, and then brush all the walls with the brush that paints the wall, and then brush the second time after the wall is dry.

Generally, a wall brush is brushed from beginning to end, and then it can be brushed from beginning to end for a second time. If the lime mortar is too thin, brush it a third time, or a fourth time, until the walls are whitewashed.

Nowadays, you don't generally use lime to paint the wall, there is a kind of wall painting powder seems to be called feldspar powder or what powder, you go to the building materials store and ask them will tell you what materials to use, what tools, how to do it.

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.

Scrape off or stick wallpaper.

Under normal circumstances, the wall skin should be removed to the cement layer first; Then brush the interface agent; Then scrape the waterproof putty 2-3 times; Finally, the base coat can be painted.

If you find it troublesome, you can directly paste wallpaper to cover it. The white ash on the wall is mainly caused by the dampness of the wall, the poor foundation of the base layer or the substandard construction process.

Wallpapering is not a necessary step, but you can decide according to your preference. But pay attention to the choice of glue, try to choose one with low formaldehyde content. In addition, about two days after the wallpaper is pasted, you can open the window for ventilation to remove formaldehyde.

White ash on the freshly painted wall is a very common phenomenon, often caused by building materials, construction technology, environmental humidity, construction temperature and other reasons. This situation not only affects the aesthetics of the wall, but also affects the durability of the wall. Therefore, if there is a situation of white ash after construction, we have to deal with it in time.

Generally speaking, there are several ways to deal with white ash:

1.Plastering.

The plastering method is to clean up the dust, sand and other impurities in the slurry and the moisture in the slurry, and re-brush after drying. First, clean the dirt and debris on the wall, then splash water on the wall, wait for a few minutes, and when the moisture is absorbed, gently wipe it with a rag.

2.Grinding method.

The method is to use the white ash layer on the wall as an abrasive, so that the original white ash is mixed with the new paint to completely remove the white ash. The method is to slowly polish the surface with sandpaper or a sander before the white ash is dry, remove the white ash layer until the paint and gypsum layer are evenly mixed, and then clean the white ash with water.

3.Secondary brushing method.

When using the secondary painting method, repaint the white ash on the wall. The advantage of this method is that it is simple and easy to operate, you only need to wait on the wall until the white ash is dry, and then apply a new latex paint on top of the new paint. This method is time-saving and can be used to prevent the appearance of white ash.

After the white ash is treated, anti-white ash measures can also be carried out on the wall, such as increasing the ambient temperature, controlling the relative humidity, selecting high-quality paints, and so on. These measures can both improve the aesthetics and durability of the wall.

To sum up, the appearance of white ash is a very common phenomenon when painting walls. After the construction bureau is careful, we can choose the plaster washing method, the ash grinding method, the secondary painting method and other methods to deal with the white ash, and at the same time, before the wall construction, we should also take the necessary anti-white ash measures to prevent the occurrence of this phenomenon. In this way, the quality of the wall can be guaranteed and the aesthetics of the wall can be improved.

Dust can be hard to avoid after the walls have been whitewashed, especially if nothing has been done to cover the furniture and floors while the walls have been painted. If not cleaned up in time, dust will have a bad impact on the indoor environment, and it will also reduce the overall aesthetic defect of the room. Here are a few simple and practical ways to clean up the dust from whitewashed walls:

1.A clean, soft cloth: Using a clean, soft cloth to wipe the dust on the wall after whitening is the most basic and effective method. During the wiping process, special care should be taken not to use stiff brushes or rough clothing, otherwise it will cause damage to the wall.

2.Vacuum cleaner: Using a vacuum cleaner to clean up the dust on the wall after whitening is also a good way to argue.

When using a vacuum cleaner, you need to adjust the suction power and choose the appropriate nozzle to avoid damaging the wall. If there is a lot of dust, you can prepare a vacuum cleaner suction bag with more cavities to avoid repeated cleaning.

3.Dust can be wiped from the corners of the wall with mild detergents, soapy water, etc. Wipe with a dry towel first, then spray with detergent, and wipe with another clean towel.

4.Sprayer: Using a sprayer to clean up the dust on the wall after it has been whitewashed is also a good way to do it. The cleaner needs to be added to the sprayer before spraying and then sprayed directly onto the wall. Wait a few minutes before wiping with a clean cloth and the dust will be completely removed.

5.Detergents: Particularly stubborn wall dust can be cleaned up with detergents.

Start by choosing a suitable cleaner, then pour it into the water and stir well. Then use a damp cloth dipped in detergent and wipe the wall. Be careful not to pour the cleaner onto a dry wall and wipe it directly.

In short, cleaning the dust after the wall has been whitewashed is a tedious process, but with a few simple tips and tools, we can easily remove the dust from our home, which can not only keep the indoor environment clean and tidy, but also make our home more beautiful and comfortable.

4. Scrape putty: Generally, the wall can be scraped twice with putty, which can not only be flattened, but also cover its background color. If the flatness of the putty is low, it will need to be scraped several times in individual areas.

If the flatness is very poor and the wall is very tilted, you can scrape the plaster first, then flatten, and then scrape the putty.

5. Grinding putty: After all the strength of the water-resistant putty is increased, it will become particularly solid, and it will become particularly difficult to polish it at this time. Therefore, it is recommended that you can start putty grinding 1-2 days after scraping the putty.

6. Brush the primer: After cleaning the floating dust on the surface of the putty after polishing, you can apply the primer. The primer can be applied once, but it must be very even.

It should be noted that both erasers and white rags need to be clean and white, so as not to cause secondary pollution to the wall due to color fading or dirty transmission.

Detergent cleaning: In order to avoid the possibility of detergent damage to the wall, dilute the detergent before cleaning, and the diluted liquid can be sprayed on the rag and used to wipe the dirty wall. <
