Can the wall tiles be painted?

1. Because I have lived in the house for a long time, the indoor walls are usually dirty or yellow, and even the tiles can't escape years of erosion. Over time, tiles will change color and be damaged. The waterproof effect is still very good, no doubt. However, it also affects the beauty of the owner's eyes. If all the tiles are removed and replaced, it will be a huge and unnecessary project.

Generally speaking, wall tiles will become obsolete, but as long as they are not particularly damaged, their functions will not be affected. Speaking of this, many owners have questions. Because the renovation of old tiles is mainly to improve the aesthetic feeling of tiles, can you brush tiles directly on the wall? Let's talk about old tiles. Think about it and see if you can brush them directly. The answer to this question is yes. Old tiles can be painted directly.

3. According to the types of tiles and materials, tiles and polished tiles made of different materials in different countries are more difficult to build.

After all, it is only "superficial". Therefore, there are still some problems if you want your home to have a truly profound change in decoration style and be more beautiful and comfortable.

Construction method of wall tile painting

1. Basic treatment will clean up the peeling and loose parts of the wall and repair them with cement mortar. Where there are cracks, kraft paper tape and white latex are generally used to stick the cracks. Non-load-bearing walls such as lightweight walls and thermal insulation walls generally need to be pasted. Try to choose better wall cloth and white latex or grid cloth, and the anti-cracking effect of grid cloth will be better.

2. Brush the interface agent. The interfacial agent can enhance the adhesion with the base, and avoid the phenomenon of hollowing and shelling of the plastering layer, thus replacing the manual roughening treatment, saving time and effort. When you brush the interface agent, you must brush it evenly.

3. Wall leveling The uneven wall needs leveling, and the uneven wall should be leveled with plastering gypsum, so that the error of the wall is not more than 3 mm ... If the angle of Yin and Yang is not straight, it needs to be plastered and scraped straight with a ruler.

4. Batch scraping should use putty with high particle fineness and hard texture, and the putty should be approved for three times. The first pass is generally thicker because it involves leveling. The second and third passes are relatively thin, mainly for lighting and making the wall look smoother and flatter. After three batches, the thickness of putty should not exceed 3mm, otherwise it is easy to crack.

5. Polishing is a key step in the painter's steps. After polishing, the final painting effect can be very good. Try to use thinner sandpaper. If the sandpaper is too thick, it will leave deep sand marks. The polished wall must be thoroughly cleaned to avoid too much dust and affect the adhesion of paint. The concave-convex difference shall not exceed 3mm.

6. Brush the primer. Primer must be brushed evenly to ensure that every part of the wall is brushed. If the wall eats a lot of paint, it is best to add a little more water to the primer to ensure uniform painting.

7. There will be some flaws in the putty after polishing, which is difficult to see under normal circumstances. It will be obvious after painting. At this time, it needs to be repaired. Pay attention to polishing and leveling before brushing the primer with a little more water, so as to avoid the color difference when brushing the top coat because of the different water consumption from other walls.
