A: Generally speaking, the putty on the wall in the family decoration should be done twice, the first time is to level the whole wall, and the second time is to do local treatment for the place without leveling But sometimes we will find that the putty on the wall is arched Why? According to observation, most of the reasons for this situation are because the first time of putty is not completely dry, so the workers apply the second time of putty As a result, the second time of putty is arched during the drying process of the first time of putty Q: what needs to be done before painting the ceiling and walls? A: before painting the walls and ceilings, the walls should be cleaned, the dust and excess putty on the walls should be cleaned, the cracks should be treated, and the junction of the walls and ceiling boards and wood products should be protected to prevent the wood products from being painted Q: why do you choose a paint brush that doesn't shed hair? A: some workers use a paint brush with poor quality and love to shed hair When using such a brush to brush paint, they often hang the brush hair on the paint surface After the paint film is formed, it will stay on the paint, which has a great impact on the effect of the paint Therefore, when painting, you should try to use a better quality paint brush If it's a new brush, also pay attention to knock the easily fallen hairs on the brush, or use a lighter to burn the floating hairs Q: how many times do you brush the paint on the ceiling and walls? A: Generally speaking, if the bottom color of the wall is lighter, you can brush the paint on the ceiling and the Wall twice, but if the bottom color is darker, and the color of the paint you are going to brush is lighter, you should brush it several times according to the covering degree of the paint color However, it should be noted that the more times the paint is applied, the better If the number of times the paint is applied is too much, the phenomenon of peeling and cracking is easy to occur Q: what protective measures should be taken for the hardware when the painters brush the paint? A: we sometimes find that when the painters brush the paint, the hardware installed on the woodwork (such as the door lock, hinge, etc.) is also painted As a result, the owners will find that the surface of the hardware is corroded when they move in Therefore, before painting, the painter should stick some single-sided tape on the parts that are easy to be painted to protect the hardware [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
