Open the window a little crack, let some dry air in, and then close the window again, maintain the humidity, through many such cycles, to achieve that the indoor air gradually becomes dry and keeps the wall dry, latex paint.
The drying speed is the same, now you can only wait for it to dry thoroughly, and after drying, use putty to repair the rough part of the wall, and then polish it, and then brush the latex paint again once. After the putty batch at home was scraped, there were many uneven places. If you use sandpaper to sand, you will find that it is so dull, this is putty loss If the old house is renovated, then the wall should be removed from the original putty layer, and the wall should be cleaned up, and the wall should be painted.
Make sure the walls are dust-free.
whitening and other phenomena. The damaged parts of the plastering layer of the wall need to be repaired in advance before the follow-up construction work can be carried out.
<> the first putty is not dry and the first putty is scraped, there will be blistering like the picture above, if the first putty is only 8 dry when the weather is hot, the second putty construction can be carried out, that is, before brushing the latex paint, be sure to check whether the strength of the putty has been dry. If the putty layer is not dry, it is not allowed to drag the latex paint at this time, which are the most basic requirements of some operating specifications.
The base layer of the fruit has been scraped with large white putty; After the large white putty is removed, all the base layers are rolled with wall solids. 1.Use a drum dipped in water to roll the base layer of large white putty twice, and wait for the original base layer to be soaked to facilitate eradicationIn the construction process, special attention should be paid to the phenomenon of dry and wet on the surface of the putty layer.
Putty powder. The nature is different, and the drying time is also different. It takes about 3 days for ordinary putty powder to dry completely, and about 1 week for water-resistant putty powder. The walls should be clean, free of dust and oil stains.
In this case, the oil stains or dirt on the bottom of the latex paint will corrode the latex paint, and there may also be imprints, especially if the latex paint is not particularly thick.

1. Wall cracking: the putty itself has a lot of water content, so the standard construction specification is to wait for the putty to be completely dry before proceeding to the next step.
2. Wall"Flowering"Generally, the wall will have a cement layer, if the putty is not dry and the latex paint is brushed, the moisture in the putty will be mixed with the cement layer wall alkali to penetrate, which will lead to obvious water traces on the wall and the wall will become flowery.
3. The wall is damp and mildew: we all know that latex paint has a paint film, and if the putty is not completely dry, it is easy to close the putty by brushing latex paint, and the putty moisture cannot be released and evaporated, so that the wall is easy to appear moldy, and it is mildew in serious cases.

I don't think it's good because doing so will cause the walls to be unstable and may come off the powder later.

The wall scrapes the putty, if it is not dry, we know that the putty surface contains water, and only when its water evaporates naturally, it will form a certain strength, so as to ensure that the putty wall is finally smooth and has a certain strength.
If the moisture in the putty cannot come out, there may be two results, the first is to cause bubbles in the surface layer of latex paint, and finally the latex paint will peel and fall off. The second possibility is that the moisture in the putty penetrates into the wall, and the final result is that there are subtle cracks in the surface layer of the wall, and there is also the fact that the moisture inside cannot come out, which will also lead to the yellowing of the wall.

will crack. In winter, the temperature is low, and the putty is easy to be frozen, resulting in the moisture in the putty not volatilizing for a long time. If the temperature is not very low in winter and the workers operate properly, cracking will not occur.
Generally, scrape three times, and after drying, polish it with sandpaper. This step is carried out before the latex paint is applied. 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.
The main points of operation of scraping putty
1. If you originally brushed lime or paint, if you want to brush latex paint, you must first remove the original wall and scrape the putty again.
2. If you want to paint a colored room, you can directly buy latex paint with color, if you redeem it yourself, you must redeem it at one time, otherwise there is a color difference, of course, the gradual color difference is also a decorative effect.
3. The quality of the roller brush must be good, the hair quality is moderate, and the density is uniform, which affects the painting effect.
4. Paint the ceiling first, then the wall.
5. Be sure to dry it for the first time and brush it again again, and use even force.
6. Brush the light color 2 times, if you want a strong color, brush it 3 times to be even.

The role of putty is mainly leveling, and the principle of a small number of times should be mastered when using, and the drying time should be extended as much as possible to ensure that the construction is carried out normally; As mentioned in lz, possible problems:
1. The batch scraping is uneven, easy to wrinkle, and the surface is rough;
2. The volatilization of internal water is affected, and local bubbles may occur;
3. The inner layer of putty is not firm, which reduces adhesion;
In any case, it is not recommended to apply the second putty construction and maintenance when the first putty construction and maintenance do not meet the requirements.

Hello answer: Because the first putty is not strong, it is still in a very soft state. At this time, you can change your imagination to scrape the putty on the soft putty layer, which will drive the putty at the bottom layer, and the more you scrape, the more uneven it becomes.
In the end, the entire wall was uneven and folded.
After the first putty has dried to eighty percent. It is absolutely impossible to scrape the putty a second time. There will be a lot of problems in the later stage. Especially once the latex paint is applied, the latex paint will temporarily cover these problems, but after a long time, all the problems will appear again.
Extended information: Since when scraping putty, you don't wait for the first putty to dry, just scrape the putty for the second time. Since the water in the first putty did not evaporate completely, the putty was not in a solidified state.
When scraping the putty for the second time, the first putty is enclosed inside, and the water cannot evaporate outward, which causes the surface putty to bulge, blister, and fold in many places, and there will be cracking in many places in serious cases.
Batch scraping putty is carried out on both sides of the bottom. It means that the first putty is primed, and the putty is completely numbered, that is, the second putty is scraped after drying;
After waiting for the second putty to dry completely, carry out the third batch scraping. The first two coats of putty do not require a particularly fine batch of scraping, while the third putty needs to be scraped particularly fine, and the flatness requirements are very high. Because if the putty is not handled well these three times, the surface layer of latex paint will be ugly.
Does the question fall off?

The consequences are very serious, the surface and the inside dry at different speeds, it will crack, why should you be anxious for a while, when the time comes to crack and make up, your time is not a little 2 points.

If the putty is not dry for the first time, it will be scraped a second time, which is easy to cause it to fall off.
The uneven gap of the wall should be greater than 5mm, leveling - sticking - and then full of putty 2-3 times, this treatment method is actually lacking in shortcomings, but also due to too thick cracks, hollow drums, etc., not to mention the first putty in the case of not drying!
It is right not to open the window, but in the future, if the wall is hit or nailed to the wall, it will easily fall off, and it will appear like a pancake.

It's not good to paint.
If it is gypsum putty, it is best to scrape it a second time before it dries.
Generally, ordinary lime and gypsum putty are not dry and scraped for the second time, but the second time will be longer after scraping, and it needs to be sprayed after drying for the second time.

Summary. Hello dear. No problem.
Putty powder can be used directly with water, the ratio of powder to water is about about right, and it can be scraped on the base surface that needs to be constructed by stirring evenly. Usually putty is gypsum or cement-based, so that the surface is rough and it is easier to bond firmly. However, during construction, it is still necessary to apply a layer of interface agent on the base layer to seal the base layer and improve the adhesion of the wall, so that the putty can be better bonded to the base surface.
Scrape the white, scrape the plaster, it doesn't dry, and the putty powder that is scraped directly, is there a problem.
Hello, it is a pleasure to serve you, the answer to your question is being queried and sorted out, please wait a moment. Thank you.
Hello dear. There is no problem with putty powder and sensitive water, the ratio of powder to water is about about right, and it can be scraped on the base surface that needs to be constructed by stirring evenly. Usually putty is gypsum or cement-based, so that the surface is rough and it is easier to bond firmly.
However, during construction, Jichang still has to apply a layer of interface agent on the base layer to seal the base layer and improve the adhesion of the wall, so that the putty can be better bonded to the base surface. <>

No way. In this way, the aftermath is endless, and the latex paint will blister. To fall off, wait for the wall to dry before scraping putty.
1. Process flow: base treatment, repair putty, scrape putty, apply the first emulsion thin coating, apply the second emulsion thin coating, apply the third emulsion thin coating.
2. Base treatment: First of all, remove the peeling, loosening and bulging on the wall and other base layers, and remove the dust, dirt, splash foam and mortar flow marks and other debris remaining on the surface of the base layer.
4. Scraping putty: the number of times of scraping putty can be determined by the flatness of the base or wall, generally three times, the ratio of putty is the weight ratio, there are two kinds, one is suitable for indoor putty, the mix ratio is: polyvinyl acetate emulsion (i.e. white latex) talc powder or large white powder 2% carboxymethyl cellulose solution = 1 5; The second is putty suitable for exterior walls, kitchens, toilets, and bathrooms, and its mix ratio is:
Polyvinyl acetate emulsion cement water = 1 5 1. Don't use it incorrectly. Here's how:
The first time with a rubber scraper transverse full scrape, a scraper followed by a scraper, the joint shall not be left behind, each scraper finally closes, pay attention to the collection to be clean and neat. After drying, grind with No. 1 sandpaper, smooth and polish the floating putty and stains, and then clean the wall. The second time with a rubber scraper vertical full scrape, the materials and methods used are the same as the first putty, after drying, with No. 1 sandpaper smoothed and cleaned.
The third time use a rubber scraper to find the putty, use the steel scraper to scrape the putty, scrape the wall and other base layers, and then smooth and polish with fine sandpaper after drying, pay attention not to miss the grinding or grind the putty through.
5. Apply the first emulsion thin paint: the application sequence is to brush the top plate first and then the wall, and the wall should be up and down first. Clean the wall first, and then use a cloth to wipe the dust off the wall.
The thin emulsion paint is generally brushed with a pen, and when using a new pen, pay attention to removing the hair of the active pen. The emulsion thin paint should be stirred evenly before use, and diluted with water appropriately to prevent the first coat from being applied to prevent the first coating. After drying, the putty is refilled, and after the putty is dried, it is polished with sandpaper and cleaned.
6. Apply the second emulsion thin coating: the operation requirements are the same as the first time, and the use should be fully stirred before use, if it is not very thick, it is not appropriate to add water or add as little water as possible. In case the bottom is exposed. After the paint film is dried, use fine sandpaper to polish off the small bumps on the wall and the brush bristles, and clean them after grinding them smooth.
7. Apply the third emulsion thin coating: the operation requirements are the same as the second emulsion thin coating. Because the latex paint film dries quickly, it should be operated continuously and quickly, starting from one end and gradually brushing to the other end, paying attention to the connection between the upper and lower brushes, and the latter row of pens is immediately followed by the previous row of pens to avoid drying and then dealing with the joints.
Generally, the putty can be brushed with latex paint in three to five days after scraping. But according to the local weather, you can't brush it until he's done anyway. The construction of plastering is generally one plaster, two putty, and two latex paints. >>>More
