Can you not polish the putty after the decoration is scraped? Why?

The wall is polished, which refers to the step of grinding the wall after the blower is smoked, and the putty is polished. In wall decoration, polishing is the fourth step. Wall grinding not only makes the wall flatter after painting, but it also solves many small defects.

Through our previous introduction, many friends have a certain understanding of putty batch, paint coating, but it doesn't understand much about walls, today we will talk about the knowledge of walls, I hope there are some people. Help.

01 Why do you want to make a wall?

Can you scratch your putty? Can you wear it? We have already said that everyone says that the main effect of putty bad is to find the walls, but if you find a fair job, if you only rely on batch putty, it is difficult to do so.

Due to some small defects in the walls of the putty, such as part of the batch is homogeneous and the knot remains in the straw, it needs to be constructed by grinding. After polishing the wall, the surface of the putty can be smooth and smooth, and the thickness is uniform, so as to strengthen the adsorption of latex coating and the final coating effect, and avoid the problem due to the difference in surface structure (such as local color difference of the paint).

02 Common tools for polishing.

Here, we introduce the two-way grinding process, the most important tools – the light bulb and sandpaper. Light bulbs: To make it easier to observe the flatness of the wall, construction workers usually occupy light bulbs during the polishing process.

The wattage of a bulb is usually more than 200 watts, so it can observe the flatness of the wall during the day.

Sandpaper: In the wall grinding process, we often use 80 to 600 destination sandpaper. Among them, 80,120 destination sandpaper, called **sandpaper; 180,240 mesh paper, known as medium sandpaper; 320 mesh sandpaper, called fine sandpaper.

The sandpaper is rough and the walls may have scratches; The sandpaper is too good, it will work hard and it will be difficult to smooth out the flat surface. Therefore, the choice of sandpaper is neither stronger nor finer, but it is necessary to match the walls.

In practice, the flatness of the wall must be used as the main reference target, which is usually tested with 240, 320 mesh paper. If it is grinded, it can be placed smoothly, then the walls are flattened, and then continue to be used; If it feels hard, replace the low-tech coarse sandpaper and test. On the premise of ensuring the flatness of the wall, if the coarse sandpaper is used for the first time, it is also necessary to use the fine sandpaper used in the whole sandpaper to clean the scratches and polish the coarse sandpaper again.

Smoother and flatter.

03 Precautionary measures for wall grinding.

Keep an eye on the flatness of the wall during the polishing process, and it is recommended to hold a bulb of 200 watts or more. The choice of wall sandpaper is not rough or finer, the better, generally start with the fine sandpaper to start the test, if grinding, change the sandpaper, but in the end, you still need to re-polish it again, making sure the walls are flat and free of scratches.

To ensure the service life of the wall, it is best to choose waterproof putty for wall putty; But compared with ordinary putty, waterproof putty will have certain difficulties on the walls of construction workers.

The putty is completely dry (more than 7 days), has high bond strength, and has a strong surface structure that is difficult to grind. When constructing, it is recommended to use 120 destination coarse sandpaper first, and then use 360 mesh sandpaper to grind the second.

After the decoration of the putty scraping, it is not possible not to polish, grinding is a necessary procedure for every scraping putty, because the wall can be smoothed through polishing, and some small flaws of the wall can be solved.

No, if it is not sanded, it will cause the wall to not be particularly good to paint, which will affect the result of the whole decoration.

You can't not polish, if you don't polish, there is no way to pave the wallpaper, and it will be very easy to blister in the future.

Wall scraping putty, under normal circumstances, is to be polished, and it is also an indispensable process. If you don't polish, it is to see whether the level of the batch of putty workers has reached a state beyond ordinary people, then, in the construction process is also different, first, the batch of putty leveling, the second batch of putty before drying, with a long ruler to scrape the wall, the third batch of putty, scrape the stubble to be smooth, do not leave any traces, visual smooth, as long as it can meet the acceptance standards, it is possible not to polish. There are also projects with low quality requirements, just scrape the wall white and bright, the level of putty technicians is also a little higher, and the wall can not see scratches and other quality problems, which can not be polished.

Even if the requirements or positioning of the place in the interior decoration are not high, it is still necessary to do a simple polishing and then apply latex paint. This is also a requirement for the latest decoration, and it is also the basic respect for our craftsmen. If there is no such thing as not polishing, it is not.

For example, exterior paint, and topcoat such as real stone paint, texture paint, etc. Because this kind of exterior wall paint is granular, rough-surfaced, it does not affect the flatness.

Under normal circumstances, the wall is made of latex paint, wallpaper, wall cloth finish, and putty all need to be polished before the construction of the surface layer can be carried out. After two or three batches of putty, repair the wall defects, adjust the flatness of the wall, and then polish the wall to make it further smooth and delicate, so as to prepare for the next latex paint, wallpaper, and wall cloth finishes. The function of grinding is to eliminate the traces of batch scraping and further improve the flatness and delicacy of the wall.

It does not need to be polished, the putty directly survives is called putty straightforward, in order to ensure a certain strength and prevent ash, a certain glue needs to be added to the putty. Depending on the original condition of the wall, it also needs to go through two or three coats of putty, and the last putty is calendered to survive. This practice was very popular more than two decades ago and is still widely used in some rural areas.

The advantage of putty straightforwardness is that the wall surface is very smooth and delicate, which even surpasses latex paint. The disadvantage is that a large amount of glue needs to be added during the construction process, and the environmental protection is slightly poor. In addition, putty is straightforward and has almost no resistance to scrubbing, and stains can easily seep in.

Only grinding can be smoother and smoother, so that the putty can be kept longer, and there will be no bulging, so that the overall effect will be better.

After scraping the putty, it is not possible not to polish, if it is not polished, there will be a bulging phenomenon, and it will be particularly easy to fall ash. If you don't polish, there will be bulging, and it will be particularly easy to get dirty.

No, it will, and this will affect the overall beauty of the interior of the room, and then it may also lead to substandard decoration quality, and then it may also fall off the wall.

It is best to polish, not not to polish, if not polished, there will be some bulging situations.

The putty cannot be directly applied to the latex paint without polishing, because it is difficult to brush the latex paint, and even if it is barely brushed, it will fall off in a short time. Therefore, before painting latex paint, the wall foundation must be treated well, and every process can not be saved. Otherwise, after the construction is completed, the hollow skin is prone to wall skin peeling, bubbles and cracking.

Precautions for brushing latex paint:

1. When painting latex paint, in order to keep the ground tidy, you can find some things to spread on the ground, such as discarded fabrics or old newspapers. In this way, in the process of painting, even if the latex paint accidentally falls down, it will not stain the ground.

2. For families who partially paint the wall, you can put the wall that does not need to be painted with a barrier, so that during the construction process, the other walls will not be stained.

3. After the latex paint is painted, if there is any remaining material that has not been used up, but the jar has been opened, it must be sealed and preserved. However, if you are afraid of surface crusting or deterioration, you can also choose to pour out the remaining materials so as not to affect the construction effect.

4. In the process of painting latex paint, if the construction wall has not been completely painted, then the drum can not be cleaned, as long as it is wrapped with plastic film. <>

Is it okay to paint putty after half a year of grinding: It is okay to brush latex paint after half a year without preparing a mold, but you need to polish the wall before painting. After the putty is scraped, it is polished after drying, and the slow grinding is to make the wall surface smooth and smooth.

Whether it is reached or not, you can check. The inspection method can be observed with a 200-watt white woven lamp against the wall to see if it is flat.

Dear, it is recommended that the sooner the better. Over time, the sanded wall will have dust and dirt, which is easy to reduce the adhesion of the topcoat, or re-polish.

It has been more than 1 month since the putty was scraped, because we are in the north here, and now the hail temperature is minus 11 degrees, and it is impossible to start brushing the milk and quietly Shouling rubber paint, you see, it is better to brush latex paint in a few months?

Pro, brushing latex paint has requirements for weather temperature Brushing latex paint should be constructed under 10 35 temperature conditions.

Dear, you can see that the weather temperature will rise in the next few months.

Now the weather is getting colder and colder, 3 months later, the temperature will rise to the appropriate temperature of latex paint, and then the putty will be polished for more than 4 months.

Dear, no, there is no impact, 4 months will not fall much dust, close the room tightly.

Does putty oxidize?

Dear, no. If you turn on the ** air conditioner to raise the temperature, can you brush latex paint now?

Dear, it's completely okay to turn on the air conditioner and brush the latex paint, and the temperature of the air conditioner is not too high. Recently, the Shanghai area has been shrouded in rainy weather, and the time required for natural drying is at least 2 to 3 days.

**Will the air from the air conditioner's outlet be affected? Will it be bragging? Will it dry unevenly?

Dear, considering that the uniformity and temperature are not up to standard, it is recommended that you spend 3 months in the construction.
