First, how can putty be scraped quickly and smoothly?

1. First, it is very important to choose good quality putty, which is the premise of scraping putty. In addition, different putty should be used for internal and external walls, such as ordinary putty for internal walls and flexible putty for external walls.

2. Understand the proportion of putty and water, and stir up high-quality putty. First, put a proper amount of water into the bucket in proportion, then pour a proper amount of putty powder, replace the electric hammer with a stirring head, and electrify and stir until it becomes slurry.

3. Before scraping, it is very important to clean the wall with broom and putty knife and clean the base of the wall. If there are cracks or missing corners, we will use gypsum powder to repair them, either sticking cloth or kraft paper.

4. Blow be bored with child, if found to have protruding sand or other sundry, should be handled in time. If you want to blow putty quickly and well, you need to master certain skills, first blow the top and the upper part of the wall, and finally blow the lower part of the wall.

The key point of scraping putty is that the wrist force should be uniform, and the scraper should be scraped obliquely, so that excess putty can be collected. When scraping the wall, try to scrape it from side to side, not up and down.

5. Generally, putty is scraped three times. When you brush, you must finish the second time in the first time to avoid brushing off the wall.

6. We'd better control the thickness of putty at about 2mm, and it's better not to exceed this size requirement.

7. For calendering, the angle of Yin and Yang must be treated vertically and horizontally.

8. Be sure to avoid cold air blowing directly, so that although it seems to dry the wall, it actually locks the water in the wall. If the next operation is carried out at this time, when heating in winter, the wall materials that have not been dried thoroughly will begin to evaporate and appear "dry crack".

9. The quality of roller brush is also the key to consider the quality of putty scraping. Therefore, the roller brush must be bought well, and the wool quality and wool quantity need to be moderate and uniform. After all, this directly affects the painting effect.

Second, the solution of putty powder

What is putty powder falling?

After the decoration construction is finished and dried, the powder drops manually.

Reason:

1. If the polishing time of the putty powder on the inner wall is not well grasped, the powder will fall off after the surface is dried and polished.

2. Exterior wall putty powder, the coating is relatively thin when facing. Under the high temperature in summer, the water volatilizes quickly, and the surface layer fails to have enough water to solidify, which is easy to remove powder.

3. The product quality is not up to standard, the product exceeds the shelf life, and the bonding strength is greatly reduced.

4. If the product is not stored properly, the adhesion will be greatly reduced after moisture absorption.

5. The high water absorption at the grass-roots level leads to the fast drying speed of putty, and there is not enough water to solidify, which leads to pulverization.

6. When the temperature is low and the putty is not completely dry, polish the surface of the putty.
