What are the steps to shave a big white? What to look out for?

Scraping the big white is on the rough surface of the cement, scraping the wall with the big white powder used in the building, and the specific steps are first to treat the original big white on the base layer to check whether there are gaps, nail grooves, rust spots on the wall. If there are gaps, fill in the plaster, brush the wall and fix the wall chain, and then scrape the plaster on the roof of the house, and then scrape the white, it is more important to scrape the white, at least twice. After drying, use sandpaper to grind off the small bag and scraper printing tracks, etc., and the last step is to brush or spray latex paint.

1. Clean up the moisture, peeling and mildew parts of the wall.

2. The base layer is waterproofed.

3. Scrape the big white and brush the latex paint (remove the original big white). It should be clean [if it is very white, it is very good, and it can not be sprayed with water, so it can be not].

2. (interface processing). Brush the wall and fix the wall chain.

Three (local scraping of plaster adhesive bandage). Check that there are no gaps on the wall, for example, there is a feeding port on the wall, and the gypsum line is modeled on the gypsum board. If there is a gap, fill it with plaster first, and then brush it with white latex and stick a bandage.

Check whether there are rust spots on the wall [nail rebar head], if so, use a machine to knock it off and then fill it with plaster.

Four (batch scraping plaster). [Note; The roof of all houses should be full of plaster, because the roof is very uneven after shoveling off the white] can not be directly scraped white. There is a big difference between plaster and white.

Before batch scraping, the work of plaster was; All places where bandages are pasted, drywall, cement surfaces. All have to scrape the plaster.

Five (batch scraping big white). [It is very important to scratch the white, at least twice.] The first time you have to scrape it all, and don't miss anything.

After the first pass, check the roof and walls for rust spots. Batch scrape the second big white. After the work is done, it is necessary to ventilate, do not be stuffy like the wind, the window can be opened for a while and closed for a while, and different weather is treated differently.

Six (polish the sandpaper after the white is completely dry). [Sanding is the work that must be done before brushing [spraying] latex paint. But at the same time, sanding sandpaper is a very important part of scraping. The scraper prints, purlins, and small packets that the builder shed when scraping the big white all have to be ground off.

Seven (do protection). So as not to stain the latex paint and rub it badly.

Eight brushes sprayed with latex paint. Note: The above are the main procedures for scraping white.

What are the steps of interior decoration scraping:

1. Grassroots treatment: If the original white does not have too many peeling places, there is no need to treat the grassroots level, as long as the local leveling is OK. If the original white is not very good or you are afraid that the white will peel after scraping, you should shovel off the original white and brush it with a strengthening or interface agent after shoveling; The main meaning of brushing is to think that there will be residual white dust left on the wall after shoveling, so as not to rise when scraping.

If you don't brush it strongly, it is recommended to brush it with white latex glue.

2. Gypsum leveling: use gypsum leveling on the uneven part of the wall or roof to bounce the line at the yin and yang corners.

3. Paste bandages: First of all, you must cut a certain gap between the joints of the gypsum board and fill it with gypsum to make the gypsum board form a whole. Attach a bandage to the seam area [white cloth or kraft paper], and put two layers on the area that is easy to crack.

4. Scrape the big white: the front process is done with the big white, there is no big white to say, as long as the normal scraping twice can be polished, grinding and grinding seems to be simple, but it is actually important, if the grinding is not good, the front process is good, and the latex paint is also ugly, and there will be scars and cracks in the place where the polishing can not be done. So be sure to shine a light bulb on it to avoid leaks.

5. Brush latex paint: be sure to sweep the dust before brushing latex paint, latex paint can add an appropriate amount of water according to the dryness of the wall, and use sandpaper to polish once after brushing, (sandpaper can be used with a larger number of meshes, generally use 600 mesh) so that there will be a better effect and feel after brushing both sides.

What to pay attention to when the interior decoration is white:

One. [It is very important to scratch the white, at least twice.] The first time you have to scrape it all, and don't miss anything. After the first pass, check the roof and walls for rust spots. Batch scrape the second big white.

Two. do protection; Wrap the area with newspaper so that it does not get latex paint on it.

Three. sandpaper sanding; Sanding sandpaper is a very important part of scraping.

Four. Brush latex paint, white less on both sides. The colored ones should be passed three times. The amount of latex paint should be carefully calculated. Because the effect of brushing latex paint is the overall effect after scraping white. The quality of the latex paint effect directly affects the overall effect after scraping.

Quality requirements for stucco engineering: square yin and yang corners, clear edges and corners, consistent color, no penetration, missing brushes, scratches, cracks, etc.

When the wall is decorated, it is generally necessary to go through the processes of leveling and scraping. So what are the steps to scrape the white? PChouse will take you to find out.

1. Do grassroots treatment and shovel wall skin.

When most people get a home from a developer and start renovating it, the first thing they do is shovel the wall. There are two reasons, one is that the quality of the original wall is not up to par, and the other is that the internal quality cannot be seen, and this is the most taboo for concealed projects. After shoveling, brush with interface agent, its main role is to improve the adsorption force of the plastering layer and the base layer, and ensure the construction quality of scraping.

2. Fill the plaster.

The professional term for plaster filling is called plaster leveling. Stretch the line on the ceiling or wall, and scrape the corners with stucco plaster. There are two types of plaster, one is to scrape the base layer and plaster, and the other is to scrape the surface layer to paint the plaster.

The full scraping base layer needs to be pasted with a glass fiber mesh cloth, and the full scraping surface layer of gypsum only needs to be stirred evenly, and then the surface can be filled and leveled.

3. Paste kraft paper.

After the plaster leveling is finished, there are some details to be handled. For example, the gap between the two pieces of gypsum board on the wall is very large, and it will crack even if it is filled with gypsum, so it is necessary to glue kraft paper at the joint between the gypsum board and the wall.

4. Scrape the white.

The first few processes are completed, and the last is to scrape the white, which is the easiest step to wipe the white, and then polish and brush the latex paint. Remember, ask the workers to supervise the work when polishing to see if it is smooth, otherwise it will be ugly to brush the latex paint.

The first step is to answer the grassroots level. Dust and magazines are removed from the surface of the wall, and the base layer is smoother. Step 2: Plaster leveling. If there is a place where the concave manuscript is trapped, use plaster for leveling work.

Step 3: Apply the bandage. Attach all joints in the wall with bandages, especially where cracks are likely to occur.

Step 4: Scrape the white. After shaving the white twice, be sure to polish it when the white is dry.

Step 5: Apply latex paint. Be sure to remove dust from the wall before painting.
