Hello, dear <>

My house wants to change the new wallpaper, do you want to tear off the old wallpaper, do you want to scrape the putty again after tearing it off, or what to do if the wallpaper is not clean, you can solve it like this: 1. You can spray some water on the wall first, and then tear off the original wallpaper. Be careful when tearing the wallpaper, don't tear it too quickly, and then it will be damaged in a large area and stick to the wall.

Then it takes a long time later to clean the walls. The base film on the wall is then shoveled off to remove it. 2. Look at the flatness of the wall and see if there are cracks or damages on the construction wall.

If there is a problem, fix it first and then scrape the putty, and then use the putty to level the wall. After we have removed and leveled the base layer under the wall, we can paint it with latex paint. Do you need to shovel all the walls for wallpaper renovation To renovate the wall, you must first check the base of the wall.

If the original base layer is good, you don't need to eradicate it all, and you can repair it properly. The wall is partially peeled off, cracked, etc., and the putty is waterproof, so it can not be completely removed. You just need to remove the decorative surface layer, then sandwork it with sandpaper and reapply the latex paint and paste the wallpaper.

If there are severe cracks, hollowing, water seepage, mold, etc., then it is likely that it is not the surface problem, but the entire wall. In this case, it is advisable to shovel off part of the wall and then do it all again. If the wall is leaking or moldy, it is likely that the waterproofing is not done well.

It is recommended to re-waterproof after shoveling. If the waterproofing is not done well, there will be water seepage and mildew in the later stage. Precautions for wallpaper renovation 1, before the wallpaper is renovated, the wall must be polished clean before the new wallpaper can be pasted.

If the wall is not sanded and the wallpaper is laid, the wallpaper cannot be completely bonded to the wall. Moreover, it will fall off after a period of use, and the uneven position on the wall must be filled with putty powder. 2. Before pasting the new wallpaper, the primer should be painted, and the primer has a moisture-proof effect.

And after applying the primer, there will be no water seepage and mold. However, when we choose wallpaper, we can choose environmentally friendly wallpaper, which does not contain formaldehyde. And after pasting the wallpaper, it should be ventilated for use, so that the wallpaper can be better pasted with the wall.

3. And when the wallpaper is renovated, if you want to paint the topcoat, you should mix the topcoat according to the proportion on the manual, and then paint it again. And after the painting is completed, be sure to ventilate for a period of time. Because the topcoat will contain some harmful gases, if these harmful gases are not ventilated at this time, then there will be some damage to the human body.

It can be applied directly to the wall paint, as this also guarantees the quality of the paste. If the original wall paint is removed and then re-brushed with putty and then pasted with wallpaper, the construction process will be straighter, but it will increase a lot of costs.

If you want to change the wallpaper again, the wall latex paint to wallpaper is not only the latex paint depends on the differentiation of the wall latex paint? If the latex paint is seriously ashed, loose, hollow gas and other phenomena, it is recommended to re-shovel the scraping putty, and then paste the wallpaper, but the original wall is basically not, do not remember the damage is not much, firmly can be repaired locally, sandpaper directly pasted wallpaper.

I don't think it's necessary to scrape all the original paint and re-apply the putty, because it is more troublesome, and it costs money and energy, so we can directly put wallpaper on it.

Before wallpapering, you don't need to scrape the putty wall clean.

Wallpaper has nothing to do with whether the wall has been scraped with putty. The key to sticking wallpaper lies in the glue of sticking wallpaper and the specific operation:

First, it is necessary to choose a special glue for sticking wallpaper;

Second, the wallpaper should be soaked with water in advance and then brushed, so that the wallpaper can be pasted on the wall more flat;

Third, the glue should be evenly and comprehensive, and there is no missing brush, so that the wallpaper can be more firmly glued to the wall;

Fourth, when pasting from top to bottom, gradually flatten the wallpaper with a dry cloth, and find that there are bubbles between the wallpaper and the wall, and the bubbles will be removed at any time to the edge of the wallpaper, or punctured with a needle to exclude the air.

Well, and only use plaster powder on the wall, don't use a big white scrape. "One" plaster scraping should be done for a day or two. "Two" sandpaper, to polish all the uneven places on the wall, the yin and yang corners of the wall should be neat.

Three: Brush the base film, don't mix with water Yo The base film is generally about 15 yuan.

It is necessary and the room should be clean and dust-free.

The flatness is required, and then the base film is brushed, and the wallpaper can be pasted after a day or two.
