Matters needing attention in painting process:
1. Choose a good brand when buying paint. Don't paint on rainy days. Try not to mix water in the construction of medium and dark latex paint, otherwise it will easily produce color difference. Gypsum board joints should be bandaged.
2. The original wall should be removed with putty, and it is best to put a cool cloth where there is a gap in the wall. Polishing of paints and coatings should be carried out after they are completely dried.
3. The paint on the metal surface should be rust-proof. If the weather is too cold, the quality of paint construction will be poor. The next paint construction must wait until the last paint is dry. When you brush the door, stick the hinge with masking paper and lock it. It's too hot, so pay attention to ventilation.
4. Brush the wall with clear oil when pasting wallpaper, remember to remove the switch and socket panel when pasting wallpaper, and protect the ground glass with newspaper.
