What should I do if the smell still doesn't go away after painting the wall?

The situation that the smell can't disperse after wall painting usually exists in the following situations:

1. Poor quality of painting materials: The quality of wall painting materials is poor, which contains a lot of organic solvents. These organic solvents have a strong pungent smell, which will be emitted after the wall is dried, resulting in stench.

2. Improper painting process: insufficient ventilation during painting leads to the volatilization of organic solvents, which can not be discharged in time, affecting the dryness of the wall and leading to lasting smell.

3. Poor cleaning: If the wall surface is not thoroughly cleaned after painting, the residual organic solvent will remain on the wall surface, resulting in peculiar smell.

So what if the smell still lingers after painting the wall?

1. ventilation: when the wall is painted and dried, it is necessary to fully ventilate and let the air circulate, so as to promote the speed of volatile organic solvents and discharge the odor as soon as possible.

2. Wash with detergent: After painting the wall, be sure to clean it thoroughly. You can choose some special cleaning agents, such as bleach and vinegar, to remove organic solvent residues.

3. Indoor humidification: In a relatively dry air environment, organic solvents will evaporate faster, so humidifiers can be used to increase indoor humidity and slow down the spread of odor.

4. Use activated carbon: It is also an effective method to put activated carbon to absorb odor. Activated carbon can absorb indoor odor and make the air fresher and more pleasant.

5. Repainting: In some cases, the painted wall smells too strong to fade easily. At this time, you may wish to spray another layer of paint, so that the new paint film can cover the original paint film, which can eliminate the original odor.

In a word, it is very important to take some measures to remove the odor after painting, which can not only improve indoor air quality, protect health, but also create a comfortable and pleasant living environment.
