I would like to ask how to putty the wall, is it feasible to do it yourself?

Hello, you don't have to find a decoration company to scrape putty, but it's not realistic for you to get it yourself, it's a project with relatively high requirements in the decoration, you can go directly to the shop that sells putty powder, and let the boss find you a putty scraper master!

The connoisseur [He Guangning] will answer for you. If mine is helpful to you, please be prompt! Your recognition is the biggest motivation for me to answer the questions! Thank you!

Putty with water and stir evenly without agglomeration, consistency to be able to be supported with a pallet without flowing downward, and then put putty on the pallet, use a scraper to get on the wall, start scraping, up and down, left and right directions, how to scrape, and then use the scraper to press and scrape thin, the beauty of scraping a part of the overlap with the upper road, the purpose is to hang up each to the edge of the plaster, after the first drying, with a flashlight against the wall to see the unevenness of the wall, with about 200 mesh sandpaper polishing smooth, and then hang the second time, Repeat 2-3 times, the wall is basically very flat, and the last time is sanded with fine sandpaper, you can brush the paint. If you have more questions, you can click on ID to consult.

It's definitely okay to do it yourself, but maybe the skills are not good, and the effect of brushing out is not good, this situation has happened to many people, it is recommended to find a professional person to do it!

1. Shovel wall skin, you can do a slight moisturizing test to check whether the adhesion of the original coating is qualified, and the vast majority of the wall surface has been inspected in one word: shovel! X0D X0A 2, the wall is closed with 801 glue, the purpose is to enhance the bonding force between the putty and the wall.

If you encounter an old house, you can brush the interface agent to increase the insurance factor. The yin angle is treated with the "elastic line" on both sides (pay attention to the verticality), and the yang angle is treated with a leaning rod. Use gypsum powder and 801 glue to prepare gypsum putty, and straighten all the gypsum putty.

There are two ways to test whether the putty is dry: first, observe whether the color is consistent; The second is to see if there is a phenomenon of "sticking sandpaper" when sanding. Strong light oblique grinding, the top surface can be 360 sandpaper.

If it's a large area, it's better to find someone to do it, it's dirty and tiring, and it may not be able to do it well.

This job seems simple, but in fact, it still requires a certain amount of skill, so I advise you to hire someone.

Here's an introductionOn the walls of the house, I plan to only scrape Wei Hong's puttyHow to scrape putty well.

I'm going to scrape only putty on the walls of my houseThe first thing we must understand is what is "putty"?I think everyone knows that in the early stage of building a house, or when there is too much decoration, there are many holes and protrusions on the surface of the walls of the house, which are very uneven, which greatly affects the overall beauty of the house is very uncomfortable, putty is the step of repairing and filling the irregular surface of the wall by filling or all the treatments of the wall, so it can be said that putty is the basic step of home decoration, just as the person's makeup should be the same as the underneath, or the putty of the house is equivalent to the bottom of the makeup. While this description is not entirely correct, it is very relevant to the image.

Then let's take a look at what putty is all about.

I'm going to scrape only putty on the walls of my houseThe scraper sounds relatively simple, but all you can say is that it sounds simple, but the actual operation is actually a bit difficult. To learn putty, it is necessary to understand the basic steps of putty.

The first step is to choose a qualified putty.

In the second step, understand the ratio of putty and water and mix evenly.

In the third step, the walls are cleaned and corners or cracks are pre-repaired using plaster.

The fourth part, the official start of putty. Under normal circumstances, you need to shave three times, but the next time you have a certain amount of dryness, you should do so.

The fifth step is the work of the putty. This is mostly done when the weather is cold.

The sixth step is polishing.

Finally, let's talk about some tips for putty.

If you want to make a putty, you must know some related skills.

1.Choose a good putty, putty is the main material that should be used when scraping putty, so the putty is selected correctly, and this work has a premise guarantee.

2.After scraping off the putty, avoid blowing cold air. Because if the cold wind blows directly, the seemingly dry wall is actually blocked by water, which is not good for the wall itself.

3.The thickness of the putty should be controlled within 2 mm and should not exceed this standard.

Zhang bought a house and prepared to scrape putty on the walls by himself, which is really not an easy thing, unless you are really determined to do it yourself, you should hire someone.

A 100 square meter house takes 4-7 days to complete.

Tools & Materials: Fine Powder (for indoor latex paint), tray, scraper, mixer, cone, broom, cloth, water.

Sandpaper (250 mesh, 360 mesh, 400 mesh), sandpaper holder, ruler, solar lamp lighting.

Masks, hats, old clothes.

Steps to scrape putty on the wall by yourself:

1.Walls should be cleaned, especially small stones on the walls. The easiest way is to scratch the sides with a palette.

The stones are basically gone, and then there will be floating ashes that can be cleaned with a broom or cloth. You can even use a hair dryer——。 However, after this blow, the visibility of the room whisperers will be very low.

Steps to scrape putty on the wall by yourself:

2.Use the tool.

It is best not to use hand glue such as wooden sticks unless it is used on a small area. If you work in a large area, you must use power tools. There are many special tools that can be sold on the internet, but it is not recommended to buy them.

If you decorate your house, you should have a hammer. At this time, you can buy a rod to remove (be sure to pay attention to the board when buying a bar).

Steps to scrape putty on the wall by yourself:

3.Start stirring, remembering one principle: add powder to the water. Once added, start stirring and stir for about 2 minutes. When shaking, shake the tamper so that all parts are evenly stirred.

4.Check whether the putty is qualified. Place the putty on the tray and the trowel is basically horizontal. The putty doesn't fall off in a few seconds, which is very good.

On the wall, for the first time two points are asked: do not come down, that is, after this time, you do not see the gray cement No. 2, try to keep it flat. It's not hard to ask these two.

5.Grinding, for the first time, you can polish the putty after drying. If it's hot, it dries out in five or six hours.

The first polish, it can use 250 mesh, it looks rough, but it doesn't matter. Because there is a second layer of putty. The grinding point is to rub the top at the seam, try to keep it level, here you should use rules and sunlight, do not use too much force, or pass through the putty.

Steps to scrape putty on the wall by yourself:

6.Clean the walls, use a broom or a hair dryer – a hair dryer is recommended, although it is very dirty.

7.The second time putty, the layer can not be too thick, see where the building requirements, it seems to be about 3mm, the main purpose is to collect light, flatness, processing, so this time, carefully do it, try not to leave holes and vents.

8.Clean the walls.

Inspect the wall and if there are holes, use a scraper to repair and polish.

If the wall is only scraped puttyAll right? I say you see if it works.

Putty is pasty on the wall and has no leveling (a property that liquid paints can achieve by controlling the surface tension), so it is prone to seams and scratches. Students who don't have a concept can consider whether there is any way to spread the toothpaste evenly on the wall without leaving seams. It's hard!

Of course, there are many people who can handle them well and avoid them as much as possible, but most people can't do it well, and with the popularity of latex paint, there are fewer and fewer people who can do it well.

Latex paint is leveled, and in order to improve the performance of latex paint in terms of paint flatness, the putty is polished before painting. Cracks on the surface of the putty were solved by grinding (there are many problems with improper grinding). Therefore, it is best to get it more evenly before the latex paint is brushed.

I believe that after the 80s and 90s, there was such an experience. The wall looks good, but if you accidentally touch it, the body is white. This is a common thing, and it's only because the putty is of poor quality.

The initial manifestation is the loss of powder (white putty), and the later manifestation is cracking and peeling.

After the improvement of latex paint, until today its standard has not been fully implemented. The most important reason is the arrival of latex paint! Even if the putty is of poor quality, at least the powder does not fall off after the paint is applied. Even if it peels off after two years, it is tolerated.

In fact, the putty is not only white. In the north, large white and ultramarine (pen water) coloring is tried, and Beijing has a putty of colored sand. But these naïve coloring techniques crumbled in front of thousands of colors of latex paint.

Therefore,If the wall is only scraped puttyThe core function of latex paint is color! Every international latex paint brand enters China. From dark to light, from light to dark, all colors have so why just use putty!

The requirements for scraping putty vary from wall to wall. Like a general concrete wall, porosity and expansion can occur. To do this, first of all, the wall is leveled, the protrusions are sanded flat, and the pits are filled.

In the case of precast concrete walls, the surface layer may produce rubble and ejecta. At this time, professional construction personnel are needed. You'll need to brush the entire wall with a wire brush.

After priming, because there are sunken places on the wall, you can use gypsum putty to flatten the landfill. Press the gypsum putty into the pit, brush the erected place horizontally, and scrape it again to ensure the smoothness of the wall.

There may be oil stains on the wall, so it is necessary to apply a lye solution, but please be careful when applying. Washing the wall with water while applying will not only speed up a little faster, but will also have an effect.

Before scraping the putty, spray the adhesive for sanding, and you can start scraping the putty. When scraping putty, be careful not to leave floating putty and scratches, and the putty should not be stained with dust, gravel and other garbage, just scrape according to the specifications.

After the first putty is sharpened, carefully check whether there is still a problem with the wall, after the putty is completely dried, carefully sanded with sandpaper, if it is still deflated, then repair and level with putty.

After the water flow is complete, the wall should be flat and smooth, with uniform patterns, and there should be no scratches on the surface of the wall. Otherwise, it will affect the overall decoration effect.

The air drum on the wall has a great effect on the adhesion of the coating, etc., and is usually inspected by visual inspection, percussion, hard engraving, and hand painting. If air bulging is found, it must be completely removed. Use matching putty to repair and flatten, or use cement mortar with the same proportion of wall mortar to repair and fill in accordance with the same construction method as the wall to ensure that the coating absorption is consistent and there are no joints.

The blank wall needs to be scanned; For the painted wall, the old paint needs to be removed, and the putty needs to be removed after more than 5 years; For walls with wallpaper, remove the wallpaper before disposing of it.

After the different wall base layers are basically cleaned, the next step is to choose the interface agent. The interface agent can improve the adhesion to the base layer and avoid the blowing of ash and the generation of shells. When applying the surfacing agent, be sure to apply it evenly.

After applying the interface agent, it is necessary to smooth out the uneven wall. For uneven walls, smooth them with plaster so that the wall error is less than 3 mm.

Walls that need to be waterproofed, such as kitchens, bathrooms and balconies, need to use waterproof coatings. In the past, waterproof materials only needed to be painted simply, but now the new waterproof coatings are mostly 2 or even 3 components.

For wall decoration, it is generally necessary to remove the original putty and paint, and then redo the wall. After removing the existing surface layer putty and coating, carefully check whether the cement (or sand ash) at the bottom layer is strong, whether there is cracking, if the bottom layer is loose, it generally needs to be pasted or continue to shovel treatment, if the bottom layer is cracked, it is also necessary to buckle the V-shaped mouth, fill the leveling plaster, and paste the bandage. Once the top layer has been removed and the base treatment is completed, the putty can be scraped.

In fact, when scraping putty, you still have a certain skill, you have to be smooth and smooth when scraping, and the putty must be just right.

1. Clean the base layer: The concrete or plastered walls, roofs, columns and joints must be carefully cleaned, and there shall be no dust, clay, splashes and oil stains.

2. Scrape the yin and yang angles: When scraping putty, the yin and yang angles are required to be clear and straight.

3. The first pass is mainly used for leveling, and the construction is carried out in turn parallel to the direction of the wall.

4. Ground grinding: try to use finer sandpaper, if it is too thick, it will leave deep sand marks, and the paint will not cover it. After sanding, the wall must be thoroughly cleaned to avoid too much dust and affect the adhesion of the paint. The difference between bumps and bumps does not exceed 3 mm.

Scraping putty refers to the most important step in the treatment of the base layer by filling or overall treatment to remove the uneven part of the surface of the base layer and keep the wall flat and smooth. First roll over the 801 glue . Go to the building materials market to buy waterproof putty (because water-resistant putty has a long service life).

Add water (preferably 801 glue) to adjust the consistency you are used to. You can scrape it against the wall (preferably three times with putty). Allow to dry.

Smooth with sand skin. It's time to brush the paint.
