2. Manual grinding (right-angle sand frame): After the first machine grinding, the second step for workers is manual grinding, which needs to be processed with a right-angle sand frame to treat the edge corners.

3. Manual grinding (small sanding frame + sandpaper): After the last two steps, sometimes there will be some edges and corners that are not polished. For some places where the right-angle sand frame cannot be sanded, we need to use a small sand frame and sandpaper to polish the small area and details one by one.

4. Brush the top surface of latex paint (primer): When our wall is sanded, there will be a layer of floating ash on the wall, and the wall needs to be cleaned. Then it's time to apply the primer.

2. Wall grinding skills, sandpaper and water-resistant putty selection. Use fine sandpaper to start the trial, when you can't move, you need to replace it with coarse sandpaper, and then you need to use fine sandpaper to polish the wall again to ensure the fineness of the wall; Although water-resistant putty is difficult to polish, it is conducive to improving the service life of the wall. We can choose to use putty with higher bond strength, the bonding strength of putty determines the service life and water resistance of the wall, so it is more cost-effective to use water-resistant putty with higher bond strength in the long term.

3. Wall polishing skills, putty polishing. Water-resistant putty needs to be polished within 3 days after being put on the wall, at this time, because the strength is low, the surface structure is not firm, and it will be more labor-saving to polish.

This method is suitable for the situation that the wall surface is relatively small, uneven or has obvious traces.

2.Putty smoothing method: Using materials such as putty or cement mortar, the entire wall is first coated with a large area, and then sanded with a sander. This method is more suitable for the situation that the wall surface is large and the surface flatness is poor.

3.Paste wallpaper method: For situations where it is difficult to smooth the wall, you can use wallpaper to cover up surface imperfections. When pasting wallpaper, you need to pay attention to making the paper as neat as possible so as not to expose the flaws of the wall.

3.Manual sanding (small sanding frame + sandpaper): After the first two steps, there are sometimes unsanded edges and corners. Where it is not possible to polish a right-angled sanding frame, it is necessary to use a small sanding rack and sandpaper to polish small areas and details one by one.

4.Apply the top latex paint (primer): After wiping the walls, a layer of ash will float on the walls, which should be cleaned up.

The primer follows. The first treatment is to seal the surface of the putty and make the wall smooth and flat. It is convenient to apply the topcoat treatment later to increase the fit of the topcoat.

When sanding, you need to be able to identify where you need to sand so that you can feel the softness of the wall with your early hail hand, and the sanding strength should be moderate and wide. After the second sanding, the putty is completely dry (after 7 days), the bond strength is high, the surface structure is hard, and the sanding is more difficult. To make the walls better, you can sandwork with 120 grit sandpaper first, and then use fine sandpaper with more than 360 mesh.

4.Building cleaning and inspection. Start by removing the paint markings from the footlines and other places; Ensure that the color of the wall meets the design requirements, that the color of the painted surface is constant, and that the wall is not allowed to have quality defects such as floor penetration, brush leakage, peeling, blistering, tear and tear bites, and falls.

This can ensure that the subsequent decoration work can be carried out more smoothly, and at the same time, it can also greatly improve the indoor environment and make the house more beautiful and comfortable.

1. If the wall is only partially uneven, you can paint the base layer of the original putty layer again, and then use sandpaper to polish the wall, and then compare the flatness with the original wall to determine that there is no problem. 2. If the wall is uneven in a large area, and the flatness error is not greater than one centimeter, and there is no problem with the wall base, you can paint putty with a thickness of 1 cm to 2 cm in the uneven position, and it needs to be leveled. Related Knowledge Development Materials:

1. If the error of the flatness of the wall is greater than one centimeter and the area is large, the crack must first remove the wall base, then use gypsum and cement mortar for leveling, and then apply putty and polish it flat. 2.
