Why do walls turn yellow after soiling? What parts should be paid attention to during decoration to reduce the occurrence of endless problems after decoration!

The main raw material of batch soil is calcium carbonate powder, which is a chemical mixture used in construction. Yellowing or discoloration will occur, which is also a type of water leakage. The main reasons why walls turn yellow after soiling are:

1. Moisture problem: If the wall is not fully dried after soiling, moisture may cause the wall to turn yellow. This may be because moisture in the lower layers of the wall is not draining properly, causing the wall to turn yellow.

2. Use of Improper Materials: Using low-quality or unsuitable earth-moving materials may cause walls to turn yellow. Some materials may contain harmful substances or change color significantly after drying.

3. Insufficient primer: If the primer is not used properly after soil batching, the adsorption capacity of the wall may be insufficient, which will affect the adhesion of the upper layer of paint and may cause the wall to turn yellow.

The reason why the wall will turn yellow is related to the moisture inside the wall. If you paint before the soil is dry, there will be moisture at the bottom, which will cause the paint to be unable to adhere to the cement wall after painting.

The reason why paint peels off is a problem in itself. Water vapor has penetrated inside the wall. If the problem of moisture inside the wall is not solved first, this situation will still happen again and again if the paint is applied multiple times.

Therefore, to completely solve the problem, it is necessary to deal with the pores inside the wall, fill the pores, and allow the water to hydrate and evaporate on its own. As long as the moisture inside the wall is removed, there will be no wall cancer when paint is applied afterwards!

To reduce post-renovation problems, here are some suggestions to consider:

1. Good ventilation: During the decoration process, it is important to maintain good ventilation, which can help moisture escape quickly and reduce the possibility of the wall turning yellow.

2. Choose high-quality materials: Choosing high-quality earth-moving materials, primers and paints can improve the durability and beauty of the decoration.

3. Guidance from professionals: If you are not sure how to carry out decoration, you can consult professional decoration personnel for advice to ensure the quality and durability of the work.

4. Reasonable construction sequence: When performing decoration, pay attention to the construction sequence to ensure that each step is fully completed to prevent subsequent problems.
