To remove the white wall from the new installation, how to remove the white wall

Hello, you can take a look at the steps to remove the white wall renovation:

Step 1: Treatment of old walls before renovation.

Before the renovation of the old wall, we need to remove the putty layer and latex paint painted on the original wall, as well as other decorations, such as wallpaper, wood decoration, etc., together with the removal. It is convenient to renovate later. If it is a newer wall, which has only been painted for less than a year or two, then just use sandpaper to polish the wall, do not have to scrape off the water-resistant putty, and repaint the wall after sanding.

Step 2: Clean the wall.

Before renovation, it is also necessary to carry out wall base treatment, and the heavily painted areas need to be completely eradicated and then plastered with white cement. Pay attention to the shoveling of the places where the bond is not strong, so as to facilitate the application of new paint.

Step 3: Primer.

When renovating old walls, remember to apply primer, which is used to seal the substrate, resist alkali and moisture, protect the topcoat and improve the texture and hiding power of the topcoat. If you don't paint the primer, you will show signs of blistering and mold over time, so you will have to renovate again.

Step 4: Extensive patching.

When renovating, the color of the original wall topcoat and the new topcoat will inevitably have a color difference, and it is more troublesome to repair because the painting time is different, and it is also prone to quality problems. Therefore, it is best to renovate the entire wall or to renovate as much as possible, so that the color difference can be avoided and the quality is better.

Step 5: Prevent color aberration.

As mentioned above, color difference is to avoid as much as possible in wall renovation, in addition to large-scale renovation, we should also estimate the amount of renovation in advance according to the description of the paint, painting. Paint the wall at one time to avoid the color difference in the secondary ratio.

1. Use an eraser to clean.

For some small wall marks or footprints, we can use an eraser to remove them.

However, when cleaning, you need to pay attention to the strength of the eraser to control it well, and not to use too much force, otherwise it will wipe the wall.

It is not suitable if the wall is dirty or the footprints are severe.

2. Use white vinegar to clean.

It must be white vinegar, not ordinary vinegar.

We mix white vinegar and water, put it in a watering can, spray it on the wall with a watering can, and then use a paper towel to wipe it down.

This method is still more suitable for some simple brushes on the wall that are dirty. After waiting for 3-5 minutes, the handwriting on the wall will become lighter and much cleaner than before.

3. Use bleach to clean.

If the wall is accidentally stained with colored stains, such as some coffee stains, etc., we can also use bleach to help clean it.

If the wall is accidentally stained with coffee stains and other stains, you should clean it up in time, wipe the water first, then dip the bleach with a towel, and gently wipe it on the wall, and the colored stains on the wall will slowly return to a white state.

1. If there is not much peeling place in the original Dabai, there is no need to treat the base level, as long as the local leveling is OK. If the original white is not very good or you are afraid that the white will peel after scraping, you should shovel off the original white and brush it with a strengthening or interface agent after shoveling; The main meaning of brushing is to think that there will be residual white dust left on the wall after shoveling, so as not to rise when scraping. If you don't brush it strongly, it is recommended to brush it with white latex glue.

2. Gypsum leveling: Use gypsum leveling on the uneven part of the wall or roof to flatten, and the yin and yang corners are springed.

3. To paste the bandage, first of all, you must cut a certain gap in the joints of the gypsum board and fill it with gypsum to make the gypsum board form a whole. Take a bandage on all the seams and paste it with white cloth or kraft paper, and it is better to stick two layers on the areas that are easy to crack.

4. Scrape the big white before the process is done to deal with the big white is not said, as long as the normal scraping twice can be, the grinding seems simple is actually more important, if the grinding is not good, the front process is good to brush the latex paint is also ugly, and there will be scars and cracks in the place where the polishing can not be done. So be sure to shine a light bulb on it to avoid leaks.

5. Before the latex paint, all the dust must be swept clean, the latex paint can be added according to the dryness of the wall to add an appropriate amount of water, after brushing once, use sandpaper to polish once, (sandpaper can be used with a larger number of meshes, generally use 600 mesh) so that there will be a better effect and feel after brushing both sides.

Quickly remove the scraping white on the wall: 1. If it is painted on the cement wall, you can use a roller to dip it in water, and then use a shovel to shovel it down after a few minutes. 2. If it is painted on a rough wall, you can also wet it with water first, and then brush it off with an iron brush.

3. If you want to paste tiles after processing Dabai, you can simply use cement and 107 glue to find the joint surface, and then paste the tiles. Scraping is a kind of interior wall decoration of buildings, and it is also the most common kind of wall decoration of ordinary residences, scraping white is actually on the rough surface of cement, with a mixture of large white powder, talcum powder and cellulose (a chemical binder, easy to dissolve in water) to fill the wall and ceiling to scrape flat and white.

Hello answer. To remove stains from white lime walls, you can wipe the stains off the walls with an eraser, or you can squeeze dish soap onto a wrung out damp rag and wipe it well, then use it to wipe the walls. In addition to this, we can also repaint the wall directly.

It seems that you want to get rid of the big white on the wall, and I think if you get the whole thing, you can spray a little less water, and then you can shovel them down with a shovel, or you can roll them with that kind of roller, that is, this point is a dip in water, so that the shovel down is very fast.

What are the main points of shaving white.

1. Grassroots treatment.

If there is no more peeling problem in the original white, there is no need to do the grassroots treatment, only need to level the part. If the surface of the original white is not smooth and flat, or if you are worried that the wall will peel after scraping off the white, you can shovel off all the original white.

After shoveling clean, brush with interface agent or strengthening, brushing to strengthen is to prevent the white from remaining on the wall, and there will be a problem of falling off the layer when used in the future. Of course, if you don't want to brush strong, you can brush with white latex glue, it also has the same effect, the base surface should be kept dry after treatment, and the moisture on the surface should not be high. And if the new cement is used for construction, the new cement needs to be maintained for about a month and a half.

2. Sticky core staring gypsum board.

It is necessary to check the part of the wall or ceiling first, if there are uneven places in these two parts, gypsum needs to be added to change and fill the leveling, and the cracked places should also be filled with gypsum to make the gypsum board form a whole without cracks, and then do a good job of the elastic line of the yin and yang corners. Then apply the bandage, which needs to be glued to the seams, and the seams that are prone to cracking need to be applied in two layers.

3. Scrape and polish.

After dealing with the wall according to the above two points, you can scrape the white, the white only needs to be scraped twice, and the wall needs to be polished after scraping. If the polishing is not good, then the wall surface after brushing the latex paint will become unsightly, and there will be more cracks and scars in the places that cannot be sanded, and the aesthetics will be greatly reduced. Therefore, be patient when grinding, you can take a light bulb to shine on the part to be polished, and avoid whether there is a place for grinding.

4. Brush latex paint and add an appropriate amount of water.

Before painting latex paint, you need to clean the dust on the wall, and you can use a feather duster to remove the dust. And the latex paint is not directly on the wall, it needs to add an appropriate amount of water to mix, according to the dryness of the wall to add water, after the first time to brush the latex paint, you need to take sandpaper sandpaper, after the grinding is completed, and then brush the second layer, and so the latex paint will feel better after drying, and it also has aesthetics.

2. Before scraping putty, the wall should be leveled with gypsum before scraping putty, and then the putty scraping construction should be carried out. Scraping putty is also to pay attention to knowledge, the material must be very delicate, and the application should be uniform to ensure that a smooth and neat effect can be formed.

3. The next step is sand repair, and the wall surface that has been plastered with putty is ground again to ensure that all the uneven places are smoothed.
