Paste the new wallpaper on the wall of the original old wallpaper

 


There are several situations in which new wallpapers are usually pasted on the walls of the original old wallpapers?


One situation is that the original substrate is not necessarily very dense, which may cause the newly pasted wallpaper to fall off after it is pasted.


There is also a second case, that is, the material of the original old wallpaper is a special high-purity wallpaper, such as high-purity wood pulp wallpaper. So we know that there are such two situations, how to deal with it now?


In fact, this is also very easy to handle, let's talk about the first case.

The first situation is that the original old wallpaper needs to be removed. After removal, it must be checked first. If the original paint is relatively tight and has not fallen off, you can directly brush the base film on it. But if the original paint is unstable, you need to remove the original paint. There is a base. Remove the putty layer and brush again.


In the second case, just soak it with a wet towel and put it on the original old wallpaper and wait for it to get soaked to see if there is any swelling. If not, you can directly paste the wallpaper on it. If there is a bulging phenomenon, all the original old wallpapers should be removed, and then the same treatment as the first case can be done.


The first step is to prepare the tools. The tools include a watering can, a paper knife, and a small shovel. The watering can and the wallpaper cutting knife are to tear off the wallpaper. Use the paper knife to cut back and forth at the bottom twice, and use a small shovel to lift a small opening. Gently tear, the force must be uniform, especially when tearing to the top, be sure to pinch the force well to prevent it from falling in the end. The old wallpaper wall and the wall began to dry up at the bottom. After the entire wallpaper was torn off, there would still be a layer of paper sticking to the wall. This is particularly easy to handle, and I personally think it is still a very interesting thing.


First, use a watering can to spray water on the paper. It should be evenly sprayed. Special attention must be paid to all the water, and there should be no missing places. After spraying, wait for a while, let the paper soak through, also start from the bottom, open a small opening, and tear it slowly. Try to keep the paper intact so that it can be removed without stepping on the stool when you reach the top.


 Wet the old wallpaper and start to exhaust it completely. Don't think that you are done when you remove this layer of paper, because a layer of glue will be applied when sticking the wallpaper. This layer of glue must be hung up, otherwise the wall paint will still be painted. not on.


First spray water on the wall, wait for a while, shovel in one direction with a shovel, you will see the results after the first shovel, I scraped one wall three times, it is best to wipe it with a damp rag. I don't care about the number of times, and finally I have to touch the wall with my hands and feel that there is no sticky glue.


There are many scratches on the wall after the wallpaper that has been glued in some places is torn off. The scratches must be scratched along the scratches. Never scratch randomly, otherwise the wall will peel and need to be repaired.

  Bedroom storage The bottom of the bed must have a higher clearance from the ground, generally 10~15cm is better , so that the dust underneath can be removed. Now there is a sweeping robot . The ground clearance must at least allow "it" to enter and exit freely; or the bed is located on the floor There are no gaps on the top, so you only need to clean around the bed. The biggest item in the bedroom is the seasonal bedding-piles of quilt pillows, which are generally stored in the "low-quality space" at the top of the bedroom closet. If the area of the room is large enough, the cabinet can be appropriately deepened, so that the bedding can be placed more loosely to avoid being squeezed by the stack to the cabinet door. Many people think that sliding doors save space. In fact, swing doors can be designed to be narrower, about 40cm, or even narrower, which does not take up too much when opened.👇 It is also recommended that the wardrobe be made upright, so that you ...
