Wall putty manufacturer construction skills of putty powder
Choose good quality putty powder
First of all, we must choose good quality putty powder. Try to choose well sold putty powder on the local market and good reputation. Good putty powder can guarantee the quality of construction, good quality putty powder mixer is necessary for producing good putty powder, good putty powder can ensure good construction quality.
Scratch times of wall putty
Secondly, the putty powder construction needs three times scratch, each time has it's special skill.
First time scratch,
Clean the wall (remove the peeling and cracks of the wall, repair it with cement mortar, shovel the remaining ash, and then sweep clean the wall). Let the putty bond well with the wall, creat a solid foundation for the next step work.
make the construction wall smoother.
Mixing 30% putty powder and 70% gypsum powder (modified gypsum is better) can be used for repairing material for the wall to replace traditional gypsum repair methods.
Make base material for the cement plastering (puffed, inverted) wall surface, the construction cost can be reduced and the construction quality can be improved. Base material preparation method: Mix 100 kg 425 cement and 40 kg indoor putty powder evenly, then add it to the container and mix with water for scraping.
If it is alkali wall, you can use alkali-sealing water to cover the alkali wall surface. After the alkali-sealing water is dry, use alkali-proof putty powder as the first layer of base material, and then operate according to usal wall putty working steps.
Isolation: The isolation layer can be formed after the first first scratch putty dry, because the wall structure is very complicated, such as alkali reversion, yellow reversion, partial humidity, etc., these special situation need to take different methods according to different conditions
Make the next step to absorb water evenly: the construction wall situation is not uniform seriously, especially the old wall, so the water absorption is different. To achieve the putty as bright as glass after construction, it requires the putty has the same humidity as possible during calendering to make the brightness and hardness are uniform, otherwise there will be one area bright but other area dark.
The first time scratching is very important, it must be dried thoroughly, the more dry the better, because the above effect can be achieved only when it is dried completely. The first drying time is normally 24 hours, but the time varies with wall conditions and climate conditions.
Second time scratching
Further leveling: After the first time putty is dry, you can apply the second scratching of putty for further smooth. The second scratching of putty can not too thin, and the water content of the second scratching putty paste should not be too large, that ensures the water content of the second scratching putty can be absorbed by the first putty as soon as possible (sizing), and the calendering can only be carried out after the moisture is reduced to a certain extent.
The third time scratching was carried out with a short time from the second scratching. The third time is mainly for calendering, so that the last step of the putty construction and the surface effect of the putty construction were shown in the third pass. After the second pass of squeegee, the slurry is slightly reduced, followed by the third pass of squeegee, and then begins to calender to achieve a bright and firm effect brightness and strength coexist.
The first time you use putty powder in construction, you need to find your own feelings. If you encounter an abnormal situation on a complex wall and try to solve it, you will gradually accumulate construction experience. It was found that many wall putty workers underestimated the construction of putty powder and failed to achieve the desired effect after construction. It should be an attitude of "strategic contempt for it, and tactical emphasis on it."
Ant Construction Machinery has designed and delivered larger dry mix plant for various bulk materials since the 1990s.
