Wall painting renovation Painting on old tiles or mosaics has higher requirements for the flatness of the wall and the putty layer.
Notes
Although the rapid renovation method is suitable for old mosaics and ceramic tile walls and floors with various types of finishes, it is best to use thin bricks currently on the market for newly laid ceramic tiles, with a thickness of approximately. This is more helpful in saving space, and there are no special requirements for mosaics or paint finishes.
For newly painted walls, in theory, tiles can also be laid with tile adhesive. However, for old painted walls, the topcoat and putty layer need to be removed to expose the cement mortar layer before mosaic tiles can be used on the surface. Treat the wall with a treatment agent, then use tile adhesive to lay the tiles.
Key points for renovating wallpaper in an old house
Many people think that it is much easier to decorate the walls of an old house with wallpaper than with paint. In fact, it is not the case. The previous requirements for wallpapering are no less than those for painting. It is very likely that you will have to spend a lot of effort to remove the original substrate. Let’s take a look at the key points of wallpaper renovation.
Check the original paint. If the original wall is painted with paint and you want to renovate the wall, can you just lay wallpaper on it? This needs to be considered on a case-by-case basis. If the original paint is relatively tight and has not fallen off, you can directly apply the base film on it and lay the wallpaper directly. But if the original paint is unstable, the original base will need to be removed.
Removing the hollows of old wallpaper. If the original wall is covered with wallpaper, it should also be treated separately according to the situation. Generally speaking, since the original base is not necessarily dense, it may cause the wallpaper to fall off after being laid. There is a greater risk in laying wallpaper directly on the original wallpaper. All the original wallpaper needs to be eradicated and replaced with the above The above-mentioned method of detecting the paint base is to check the base to see if further removal of the putty layer is needed.
If the original wallpaper is of special purity, such as high-purity wood pulp wallpaper, soak a wet towel in water and place it on the wallpaper. After more than ten minutes, check whether there is hollowing. If there is still no hollowing or other phenomena, you can directly lay any wallpaper on it. If there are hollow drums, all the wallpaper needs to be removed, and the next step of substrate inspection and treatment needs to be carried out.
