How to clean up the black wall of the house How to remove the white wall when it is black

Hello! The situation you mentioned can only show that the "white ash" on the wall is a layer of putty, not white cement. Due to the developer's cutting corners, too little binder is added in the putty, or the quality of the binder itself is problematic, resulting in the lack of adhesion and due strength of the putty layer, which will make the putty layer relatively loose, and the white powder will stick to the touch of the hand, and the clothes will also be stained with this powder when the body leans up.

The solution to this problem is to remove this layer of putty when decorating, and then use construction glue to roll and brush it again, and then scrape the putty again. The binder in the putty should not be too little, and an appropriate amount of white latex should be added, so as to avoid similar situations.

If you don't want to decorate now, and you want to solve this problem for the time being, then you can buy ordinary construction glue (such as 801) and roll the glue evenly onto the wall, and it will not be like this when it dries.

If you find it helpful to you, then please give it, thank you!

If there is grease on the wall you are cleaning, then you can use baking soda to clean it. Make sure you move all the items around the wall to another location before cleaning the wall. Use rubber gloves to avoid the adverse effects of soap and baking soda.

When we scrape off the white paint on the wall, we may find that there are black marks left on the wall. This usually happens quite often and is quite common, but don't worry, we can fix this very easily.

The first step is to check if the wall surface is ***. If the quality of the walls is not good, then they will be easily fragile, so we need to be very careful in the treatment process.

The second step is to prepare the required materials. We need soapy water, rags, fine sandpaper, brushes, paint fillers and wall paints.

The third step is to clean the walls with soapy water and a rag. Soak a cloth in soapy water, squeeze it dry, wring it out and gently wipe the black stains. If soapy water can't remove the stain, we can use fine sandpaper to gently sand the stained area.

But remember not to sand too hard, otherwise it will damage the texture of the wall.

The fourth step is to fill in the walls. After the soapy water treatment, we need to place the paint filler on the mark, scrape the surface of the mark, and let it dry completely. It usually takes about half an hour.

The fifth step is to apply the lacquer and apply the layer of wall paint. When it has dried and filled, we can use a fine brush to brush a layer of lacquer material to cover the wall, not forgetting to pat the newly applied coating before drying, so that a finer effect can be achieved.

If we were careful enough to spend some time fixing it, we could avoid such a headache. It is best to avoid scraping off the paint on the walls, but instead learn how to properly repair and protect the walls, which is very necessary to keep the house tidy and attractive.
