The balcony is facing south, and the master bedroom has a wall to the west and is close to the road,

You can also paste wallpaper on the head of the bed, similar to the background wall, which is quite a good effect!

What about this? It's best to do it here, but if you say you don't want to move this side, you have to do it on the other side. On the other side, paint twice with a high waterproof material, and then brush back to white with mud, and then put on a better waterproof paint OK, so it must work, I have also dealt with such a problem, the owner also said that the effect is good.

Look at what color you paste, it's not that there is no such paste, this kind of sticking is generally used in the room with a clear theme, some shops, living rooms will also be pasted like this, generally will be pasted with more contrasting colors, of course, there is also a color that can be echoed in it, although only one wall is pasted, but if you do it yourself, it will be more difficult, the possibility of sticking bad is relatively high, sticking bad is actually nothing, but sticking bad and tearing off the wall will be destroyed, so that the gain outweighs the loss, It is recommended that you can find the wallpaper installation master of Master Wan's wallpaper installation platform for help.

The phenomenon you said is because of the leakage of the pipe network under the ground or the waterproofing of the bathroom is not done well, if it is simply smeared with cement, it will not solve the fundamental problem, or will continue to be alkaline, causing the paint to fall off, it is recommended to solve the problem from the root, check the leakage point or the bathroom waterproof and then deal with it.

Tearing down the wall can be done by two people in a day, but it is necessary to understand that this wall is a load-bearing wall, and if it is 24 cm thick or more, it cannot be demolished. I hope my answer can help you.
