Whether the color difference repaired by the blank putty needs to be treated depends on the severity of the color difference. If the color difference is not obvious, you can leave it aside for the time being, because the subsequent decoration steps may cover these color differences. However, if the color difference is very obvious, it needs to be treated to ensure the unity and beauty of the decoration effect.
For the color difference that needs to be treated, the following methods can be used:
1. Fill putty: If the color difference is caused by the uneven wall, you can use the way of filling putty to level the wall, and then polish and color.
2. Re-coloring: If the color difference is caused by the uneven color of the wall, you can re-color the wall to make the color uniform and consistent.
3. Covering color difference: If there is a large area of color difference on the wall, you can use paint, wallpaper and other materials to cover the color difference to make the wall more beautiful.
It should be noted that when dealing with color difference, the appropriate method should be selected according to the specific situation, and the construction should be carried out with first-class materials and tools to ensure the beauty and durability of the treatment effect. At the same time, the wall should be cleaned and repaired before dealing with the color difference to ensure that the wall is clean and flat.
What to pay attention to when scraping putty
1. Tool selection: choose the appropriate scraper and choose it according to the construction area and needs.
2. Surface treatment: Before construction, the wall needs to be cleaned and treated to ensure that the surface is dry, smooth, free of oil and loose particles, etc. If there are burrs, you need to use sandpaper to smooth them first.
3. Putty stirring: The putty needs to be fully stirred evenly to ensure that the texture is soft and easy to brush. When stirring, you can add the right amount of water or other additives, but you should control the proportion.
4. Coating method: The putty should be applied layer by layer, and the thickness of each scraping should not exceed 2mm, so as not to cause cracking and deformation. In addition to the first layer of putty that needs to be scraped according to the requirements of the construction specification, the scraping method of other layers of putty should be adjusted according to the condition of the previous layer.
5. Time mastery: putty needs an appropriate time to dry after scraping, generally more than 24 hours. After scraping each layer of putty, you need to wait at least 3 hours before applying the next layer to avoid problems due to too fast scraping.
6. Yin and Yang angle treatment: The Yin and Yang corners of the wall should be handled well and kept vertical. It can be treated with corner strips or PVC material to increase impact resistance and prevent cracking in the corners.
7. Other treatment: For wardrobes, doors, windows and other parts connected to the wall, the gaps need to be dealt with, and paper tape or putty can be used to fill them. Before scraping putty, it is necessary to reserve the water and electricity lines to avoid later changes. For mobile furniture, it is necessary to avoid bumping against the wall.
8. Material selection: choose the best putty material, it is best to choose the finished putty powder of the big brand, and look for the national environmental protection certification. Good putty powder has the characteristics of strong adhesion, no glue, no formaldehyde, etc.
9. Grinding treatment: After the putty is dried, it needs to be polished to make the wall surface more flat and smooth. Use a suitable sandpaper or sander when sanding, and the force should be even, so as not to damage the wall.
10. Maintenance: After the construction is completed, the wall needs to be maintained and maintained. Avoid using sharp objects to scratch the wall, keep the room clean and hygienic, clean and wipe the wall regularly, etc.
The above are the things that need to be paid attention to when scraping putty, and following these steps and methods can ensure the construction quality and use effect of putty.
