Can I not polish the putty after scraping? On what basis?

Why scratch vertically? Because it is the last process, longitudinal deflection can well deal with the marks left by batch deflection. The oiliness of the last hand is also known as glossiness.

When mixing the greasy powder, add the gloss to mix evenly. Let it sit for about 5 minutes, then stir it again for even better results! Scratching the third hand putty is very technical.

It is necessary to accurately grasp the right time and strength for the finish. Using mortar, using 360-degree lightweight rotation putty polishing technology, isn't it possible for all putty masters to try it? The greasy of the third hand is polished with a skillful touch, and the walls are as smooth as a mirror!

You don't need to polish to achieve the desired result.

It's more verbose here. Why do you want to scratch and grind again? The decoration of commercial housing is more high-end than that of home, and the wall decoration can't just scrape the big white wall, right?

At least polish the decoration such as latex paint to improve the level, and it is not easy for you to buy a house. So you have to grind to scratch such a greasy thing, why? This is because repainting after polishing can improve the adhesion of the latex paint, and polishing can also further smooth the wall.

It is so greasy that it can be used directly without grinding, which is suitable for three situations. Scrape off greasy things, no need to polish, the next step, things with other decorative processing requirements do not need to be sanded, and things that are required for style do not need to be sanded.

Home decoration generally has to be scraped twice, the first time is to scrape the base layer, and the second time is to repair the surface and scrape it flat. It is usually ground evenly after the second scratch is completed. The main effect of greasy batch scratches is to level the walls, but the job of leveling is just scraping off the greasy stuff with the layout, which is difficult to do.

In the process of greasy batch flexing, small imperfections often appear in the wall surface (e.g., some batches are unevenly deflected, the junction leaves gaps, etc.), so it needs to be compensated by sanding. By sanding the wall, the greasy surface is smoother and more uniform, which can strengthen the adsorption of the latex paint and the final painting effect, and prevent problems caused by differences in surface structure (such as color difference in the paint part).

In the process of polishing the wall, we often need to use 80 600 mesh sandpaper. Of these, 80,120 intent sandpaper is called coarse sandpaper. 180,240 intent sandpaper known as intermediate sandpaper; More than 320 mesh sandpaper is called Sejong.

The sandpaper is too thick and may be scratched by the wall. The sandpaper is too fine, it is difficult to sand, and it is difficult to polish smooth. Therefore, the choice of sandpaper is not as thick as possible, but to match the scratches on the wall.

In fact, we should take the flatness of the wall as the main reference goal. Usually it is tested with 240,320 pieces of sandpaper first. If the grinding is effortless, you can level the wall and continue to use it.

If you are tired, replace and test a low amount of coarse sandpaper. On the premise of ensuring the flatness of the wall, if you use rough sandpaper for the first time, generally the whole or part of the area should be sanded again to remove the scratches left when sanding with rough sandpaper, so that the wall is smoother and smoother.

After scraping the putty, it needs to be polished, because there is another layer of other things to be smeared on the top, and the bottom layer must be polished very smooth, which is an unchangeable law.

Of course, it can be sanded, because this will make the wall smoother and more beautiful. And now after construction, it will be polished.

The wall decoration material determines the need for sanding after scraping the putty. One of the reasons for scraping putty on the wall is to solve the flatness of the wall, there is a certain concave and convex surface on the surface of some walls, if you do not use putty to level it, when constructing the wall material, it is likely to cause the folds or damage of the wall cloth or wallpaper at the concave and convex places, seriously affect the aesthetics, and cause the waste of materials. Cause.

Second, the base material of the wall decides that it needs to be polished after scraping the putty. In many cases, the base material of the wall is cement mortar, and the surface of cement mortar is generally not so smooth

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.

As long as the putty is dry, it can be polished, but it also depends on the weather, and it will dry in 2-3 days after the weather is good. In case of bad weather, it is best to wait until 3-5 days have passed, and be sure to dry thoroughly before sanding. It is best to sandpaper for sanding, and there are a few factors to be aware of:

First of all, the temperature, then the humidity, and the ventilation of the room. It depends on your own situation.

Just do it, every two days, but once you try to polish it, if you don't lose the powder, you're waiting.

It depends on the thickness of the putty, if the wall is uneven and the putty is used too much, the drying time will be increased accordingly; There is also depending on the weather, if the weather is sunny and the temperature is high, the putty will also dry faster, if it is in a rainy day, the air humidity is high and the temperature is low, then the putty is not easy to dry at this time; Under normal circumstances, the thickness of the putty is uniform and the weather is good, and the drying time of the putty is about 2 days before it can be polished.

Under normal circumstances, the construction of the first layer of putty is 3 days, and the drying period is about a week; The construction of the second layer is about 2 days, and the drying period is 3 days; The third layer is finely processed for about 2 days, and the drying period is also 2 days, and it can be polished.

Do I have to sanding the putty after scraping? Why sand? No matter what kind of decorative wall you choose, wall decoration is the largest proportion of items in home decoration. In general home decoration, we know that the wall needs to be approved to blow putty, and then apply latex paint.

After blowing putty, the process before the construction of latex paint is grinding, do you know why the wall surface of hanging putty needs to be polished? Why do you blow putty on the wall? In fact, scrape putty.

The main role is leveling, but only half of the leveling work, we can't avoid leaving some small defects in the construction process. However, putty can effectively solve these problems when polished.

<> putty will be looser after polishing, which is more conducive to the absorption and penetration of primer, so as to improve the adhesion of latex paint, so that the putty layer and the latex paint layer become one, and it is not easy to fall off, and the putty touches off the powder by hand after polishing, which is a normal phenomenon. This is because when scraping putty, there will inevitably be some minor blemishes in the process of scraping putty. For example, the joints of putty stubble, may be local scraping thinning or traces left later, because of the wall water absorption and other reasons, caused by pinholes and other defects, can be solved by wall grinding.

If you do not polish, start to do the next process, which will affect the overall effect of construction, or form a variety of uneven shapes, and repair small defects through polishing, so that the putty layer is smoother, smoother and more delicate. After polishing, the sub-layer putty is used, the surface structure is more uniform and consistent, and when we brush latex paint, we can improve the performance effect of latex paint, so as to avoid problems such as latex paint that may bring local color difference due to differences caused by surface structure. Therefore, don't ignore the boring child polishing process when decorating.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Scraping putty is definitely to be polished, if not polished, the whole wall must not look so smooth, after sanding the whole wall is very smooth and bright, and scraped very flat.

After scraping the putty, it is necessary to polish, because you only need to scrape several processes, and each process must be polished and smoothed before proceeding to the next step.

It should be polished; This can make the wall surface more flat and more detailed, and the putty on the wall can be applied more evenly and visually more comfortable.

Yes; Because sanding can make the wall smooth, and it can also fix the small defects that existed before.

The putty is scraped twice and wants to stop, and after a period of time, it is sanded and brushed with latex paint.

Yes, the reason: because of the wall scraping putty.

The key lies in leveling, said to scrape the putty powder several times.

In fact, the number of times in the back should be in the area where the front is not smoothed out. After the putty powder is scraped, it is polished and polished after drying, and the grinding and polishing is to make the wall smooth and clean. Whether it is done or not can be checked.

The inspection method can be viewed with a 200-watt white fabric lamp pressed against the wall to see if it is leveled. Generally, it is necessary to do it two to three times, and it is generally three to five days to dry at a time, and it will be a little longer in rainy days. Scraped putty powder, not prescribed light but to carry out ground leveling.

The putty powder for brushing the wall is generally required to be scraped three times, but each batch of putty is required to be done at the same time and then the next time it is brushed. When batching putty, you must avoid cold wind blowing, so that although it looks like the wall can be dried, in fact, it is to shut the water of the wall in the wall, if you carry out the next operation at this time, until the winter heating, the original wall material will begin to volatilize, the phenomenon of "cracking".

When the bottom layer is fast and strong, it is necessary to carry out a closed primer before brushing the putty powder, so as to prevent the plastic particles in the putty powder from being digested and absorbed by the bottom layer too much, which will endanger the adhesion of the putty powder. Master the slope of the imitation Zen finger tool when brushing, and use it evenly to ensure that the putty powder is rounded. In order to prevent the putty powder from being too large, cracking and falling off, it is not necessary to be too thick for brushing at one time, and the thickness is the most suitable for 0 5 1mm according to the characteristics of different putty powders.

Do not brush back and forth excessively, so as not to roll the skin, fall off and squeeze the plastic particles in the putty powder, and seal the surface layer is not easy to dry out.

According to the characteristics of the coating and the condition of the base layer, select the appropriate putty powder and special tools for brushing, and use the putty preparation knife to make up for the bottom hole and gap, the ring finger.

Clamp the cutter head, press the putty powder into the shortcomings with all your strength, spread and fill it, and scrape the putty powder around it neatly to avoid putty powder marks as much as possible.

When batching putty, do not pollute the road surface, footboard, living balcony, balcony, window door and laminated glass.

and other sub-items that have been completed. The general putty powder batch embedding should first use slaked lime.

After leveling, and then batch general putty powder, although this practice can be cost-effective, but after that, it has buried hidden dangers. The slaked lime in the walls will be carbon dioxide in the air.

reaction to form calcium bicarbonate.

Water absorption and expansion, causing the wall to crack and cause water leakage, seriously endangering the normal life of residents.
