Why does smallpox turn yellow?

Generally, the master in the industry calls yellowing "salty", which is most likely to happen in old buildings over 20 or 30 years, especially Tang buildings. If there is a shrine in the living room, the lampblack that seeps into the wall over time will also lead to yellowing. If you apply several layers of latex paint, you will "eat" it. If the painter in the industry finishes a layer of latex paint, he will find it is yellow (because yellow is often "pulled" by the water in latex paint). Generally, a layer of three-proof oil will be coated on the surface of latex paint as a sealing agent to seal the alkali yellow. It will be fine if it dries, such as yellowing. Three-proof oil is diluted with natural water. You can use a combination brush to oil, and pay attention to dripping into your eyes. This is no joke!
