The paint on the wall is uneven, and the wall is uneven and has been painted

After the paint is painted, the light hits the wall, and the phenomenon of unevenness appears laterally, which belongs to the uneven layer of cement mortar on the wall.

In the construction of wall coatings such as latex paint, experienced masters will use lights to irradiate the wall sideways to observe whether there is an uneven problem, if not, you can directly batch putty into the paint construction procedure, if the wall is uneven, it will first modulate the white cement paste, the entire wall will be scraped flat, and then you can enter the paint construction procedure of the batch putty.

For the uneven wall that has been completed, there is no other way than to rework it in a few years.

I don't know how you think it's unfair! Sometimes it can be a visual error. In many cases, the protrusion can be smoothed by re-sanding the protrusion.

Wall paint construction process: construction process: base repair, cleaning treatment, filling gaps, putty priming, leveling, grinding, sealing primer, the first coating, detailed treatment, the second coating, inspection and acceptance, paint cleaning.

If there is indeed a large area of unevenness after the wall is painted, it is mostly not leveled and polished when scraping putty, if it does affect the appearance, it is recommended to re-polish and level and re-brush.

Baohe K11 waterproof slurry is a polymer modified cement-based waterproof material made of polymer materials imported from Germany, polymer modified cement, inorganic waterproof materials with strong acid and alkali permeability, it is not only dependent on the surface coating film waterproofing, the active substances in the slurry can penetrate the capillary and micro-cracks inside the low material and produce chemical reactions, forming a crystal and integrating with the low material, thus closing the channel of water from all directions, so as to play a waterproof effect. The material is somewhat flexible and able to resist minor cracks.

Advantages of Baohe K11 waterproof coating products:

1. Green and environmentally friendly, healthy and non-toxic, can be directly used in edible drinking pools and fish ponds;

3. Plastering treatment before paving tiles, wooden floors, wallpaper and gypsum boards can effectively prevent moisture and salt pollution.

1. You need to remove the painted paint, and wait until the wall is smoothed before painting. 2. The wall can be carried out by professional decoration personnel. 3. It needs to be fixed with better reinforcing materials.

Suggested solutions: 1. The uneven wall will have a big problem in the construction process, and it will be more difficult to deal with once it is painted. If you want to solve it quickly, you need to remove the paint, sand the smooth wall and then repaint it.

To avoid this problem, the construction team tried to choose smooth materials before construction. 2. The uneven wall will not only cause visual unsightliness, but also affect the entire decoration progress. If you want to create a smooth wall perfectly, if the wall is uneven and painted, it will cause a series of problems.

If you want the walls to be smooth and not affect the painting, then you need to arrange a special technician to supervise the decoration company at all times. 3. The wall is uneven and painted, which is a wrong decision. If you want to solve the problem, you must fix it with a good fixing material, generally speaking, use sandpaper to soften the original putty on the wall, smooth the irregular wall, and use the best technology to create a smooth wall.

It is best to use a good fixing material to use the material, and try not to make errors, which can not only solve the problem of uneven wall, but also fix the irregular wall that has been painted.

First of all, we have to figure out a question: whether you have paint or latex paint on the wall now, the former is oil-based, mainly used for wood and metal surfaces, and is rarely used for wall decoration now, and the latter is water-based and is now the most used for wall painting.

If it's paint, there's only one solution:

Level with oily putty or putty, then sanded with sandpaper, first with coarse sandpaper 100 or 120, then with fine sandpaper 240 or 320. If you have a large area of the wall, it is recommended that you use oily putty Nippon has this oily putty, which should be more than 60 bags a bag, if the cost of putty is a bit high. After sanding, the interior should be cleaned (if there is floating ash during the construction process, it will affect the final wall effect).

Primer can be brushed or sprayed, but when doing topcoat, it is best to spray, not necessarily one bottom and two sides, if the first primer is done, found that there are uneven places, or scrape putty and sanding, and then do another primer, and then paint on top.

If it is latex paint, the solution is much simpler.

First, it is possible to scrape putty powder and gypsum powder directly on the base layer of latex paint, and we must first understand what the problem is. There are several possible scenarios:

1.There is no putty scraping before painting. In this case, the particularly uneven place should be leveled with white latex and gypsum (do not smooth the uneven place at one time, so that it is easy to fall off, and it should be divided into two or more times, and the principle is that the thickness of each leveling is not more than 4 mm).

Then scrape the putty powder twice, dry it and sand-smooth it with 180 or 240 sandpaper, and then you can brush the latex paint.

2.The putty is scraped, but it is not sanded or not polished thoroughly. If there is no polishing, the putty should be scraped directly on the basis of latex paint, and then sanded and smoothed, and then painted; If the polishing is not thorough, as long as the local putty or plaster leveling, sandpaper polishing and smoothing, with the same color latex paint to make a bottom and two sides, and then the part that is connected with this part (the general dividing line can be the corner of the wall) can be painted aside.

Answer: You can do it again, the thickness of the patch is controlled within 3 mm, and the protruding places can be sharpened downward. If it is too concave (within 1 cm), you can first remove the putty layer and fill the plaster, and then fill the putty after drying.

Putty (mud filling) is a decorative material that flattens the surface of the wall, is a kind of thick paste coating, and is an indispensable product before paint painting. It is applied to the primer or directly to the object to remove uneven defects on the surface of the object to be coated. It is prepared with a small amount of lacquer base, additives, a large number of fillers and an appropriate amount of coloring pigments, and the pigments used are mainly iron red, carbon black, chrome yellow, etc.

The fillers are mainly calcium bicarbonate, talcum powder, etc. It can be used to fill partially recessed work surfaces, or to scrape off the entire surface, usually after the primer layer has dried, and then apply to the surface of the primer layer. Good adhesion and no cracks are required during the baking process.

Generally, putty is divided into water-resistant putty, 821 putty, glue-doped putty, etc.

After installing a wall lamp on the wall, I saw that the wall was uneven and uncomfortable.

It's hard to see what I should ask the workers to do.

After the latex paint is done, the uneven wall can be reworked, and the latex paint is found to be uneven after the completion of the wall is uneven, and it needs to be reworked, so you can first use a coarser abrasive cloth or sandpaper to fully polish the paint film to destroy the paint film, so that it is more adhesion, more affinity, and it is not easy to cause wall cracks due to shrinkage, and then use putty powder to re-correct and scrape, and you can apply the topcoat again after grinding.

Answer: If it is a local unevenness, you can repaint directly on the original putty layer, and then use sandpaper to polish the wall, check the flatness of the wall, and paint after confirming that there is no gap. If there is a large area but the flatness error is less than 1cm, but the wall is not too much of a problem, you only need to paint putty with a thickness of about one to two centimeters on the wall, and then level.

You can only shovel out the high place and do it again, don't you use the light when you hit the sand skin to smooth it, after the light is shot against the wall, the unevenness can be seen with the naked eye. At least use the aluminum alloy strip against the wall to measure, see if there is unevenness, in fact, it is easy to see, the treatment method:

Now you can only ask the master to shovel the uneven places for you and use sand to knock off the previous latex paint.

Depending on the concave and convex area, if the whole room plane is like this, it is more troublesome, and the time is as long as above. There bumps hit there, and under putty repair, they are flattened. Of course, the color of the wall paint is not the same in the later stage, even if the same color will appear, there will be color difference, you need to roll the entire wall paint again at the same time.

Cover the previous wall in a consistent color.

1. If the decoration project is fully contracted by the decoration company, then the acceptance should be refused after the wall has problems, and the decoration company should be required to deal with it, and the quality of the repair should be guaranteed. Secondly, when the renovation company carries out wall repair, it should be supervised.

2. In general, there are three reasons for the unevenness of the wall, namely local unevenness, large-area unevenness, and errors in flatness, which should be dealt with according to the actual situation when repairing.

3. If the wall is partially uneven, this situation is easier to repair. Under normal circumstances, as long as the paint is applied on the basis of the original putty, and then the wall is smoothed with sandpaper, and then the wall flatness is compared to determine that there is no error before painting.

4. When inspecting the wall, if you find that the error of flatness is within 1 cm, and there is no problem with the wall base, you can brush 1 cm to 2 cm putty in this case, and then carry out leveling treatment. However, if the previous base of the wall is not done well, it is necessary to remove all the original wall skin and level it with cement mortar and plaster, and finally polish it with sandpaper after brushing putty.

5. If the flatness of the wall exceeds 1 cm and the area is still very large, the wall should be completely removed and leveled with cement and gypsum.

The inspection of the wall is not carried out in this way, and if it is dealt with in this way, no company can achieve it.

The use of lighting is for the polishing of the details, in order to polish the protruding part, because it is a manual operation, such an error is very normal, there is no need to think that the decoration company is very good, as long as the protruding part is re-polished.

To give you a way to check and the construction process:

Construction process: base repair, cleaning treatment, filling gaps, putty priming, leveling, sanding, sealing primer, first coating, detail treatment, second coating, inspection and acceptance, paint cleaning.
