Is it suitable for scraping putty in cold weather, and is it okay to scrape putty in sub zero weathe

Below 5 degrees Celsius.

It doesn't fit.

Below is scraping putty.

Notes:

When carrying out wall treatment, the role of the first putty is to make the wall clean and tidy, which is convenient for subsequent work. After the first putty is completely dry, the following work can be carried out.

In different cases, the first way to deal with it is also different. For the walls and old houses that fall off seriously, the original putty layer should be removed first, and the wall should be cleaned before applying the interface agent.

Then re-make the putty layer on the exposed cement wall. Before scraping putty in a new house, an alkali-resistant sealing primer should be applied before scraping putty. In some locations, the wall is uneven and the error is large, so it is necessary to use wall cloth.

Do a good job of reinforcement to prevent the wall from cracking in the later stage. The overall base wall should be clean and tidy, and the dryness and moisture content of the base should be ensured.

It cannot exceed 8%. Yin and Yang Corner.

position, to ensure square.

The thickness of the scraping putty should not be too thick, nor too thin, too thin putty is easy to expose the wall when polishing, and the putty of the queen mother is easy to cause dry cracking, blistering, and even falling off. For the large gaps and grooves on the wall, it is necessary to smooth it with plaster first, and then polish the protruding place with sandpaper after the plaster is dry, clean up the dust on the surface, and then scrape putty.

The wall is completely dry, and visually speaking, the color of the entire wall is uniformly white, and there is no graying feeling when wet. Gently stroke it with your hand, it feels very smooth and will be slightly stained with a little dust. Or use sandpaper to gently sand, a large amount of dust appears, it means that the first layer of putty has been dried, less dust or basically no dust, it means that the first putty is not dry.

The drying time of putty should be adjusted according to different climatic conditions, and the drying time needs to be extended in dark and humid climates. Under normal circumstances, the position of the yin corner is the most difficult to dry out, if the position of the yin corner is dry, then it can be basically judged that the whole wall has been dry.

The cold weather must not scrape putty, still 10 scraped up, after the spring flowers bloom, he will fall, the decoration company knows this best.

Putty application is possible in winter.

Putty powder contains a lot of chemicals, and scraping putty in winter can speed up the volatilization of formaldehyde and reduce the time for these toxic gases to remain indoors.

At the same time, the temperature is low in winter, and opening the window after the construction is completed can make the putty on the wall dry faster, and avoid the putty pulverization and cracking to a certain extent, and the film-forming effect will be better.

Although putty can be scraped in winter, the temperature should not be too low, and ventilation should be done at the right time, otherwise any improper behavior will affect the final effect.

Putty can be scraped all year round, and ideally it is best to avoid the rainy season and give preference to summer and autumn. 1. Spring and winter are not suitable for scraping putty, and the humidity in spring is heavy, especially the resurgence days in the south have a great impact on the quality of putty; Second, the cold weather in winter affects the speed and quality of putty scraping, if the weather is too cold, the putty will shrink sharply and is prone to cracks. What season is the best season to scrape putty?

1.In summer, it is more suitable to scrape putty in summer, and scraping putty powder is not easy to crack, and it is also the best season for putty batch scraping and maintenance. 2.

In autumn, the weather is dry in autumn, and the putty dries quickly, which is not easy to cause falling off and is not easy to deform after decoration. Putty scraping workers in autumn is more comfortable and better to work with.

Scraping putty can't be scraped in winter. If the weather is too cold, the putty will shrink so much that it is easy to crack, so that we need to use the sun lamp to adjust the indoor air when we work, and polish it by the way.

Tips for scraping putty.

To choose a good quality putty powder, not only can make the house look more beautiful, but also when we live in it can also play a moisture-proof effect, the most important thing is to be sure to choose environmentally friendly products, after all, these products contain more or less chemical elements. Therefore, choosing the right putty is not only good for our body, but also can make our living environment more beautiful and safe.

When blowing putty, you must not encounter cold wind, because if the cold wind blows directly on the wall, it is easy to cause the wall putty powder to peel off in the future, because the wall looks like it is dry, but in fact, the water does not evaporate at all but remains in the wall.

If it rains for a short time, if you really want to scrape, try to keep the wall dry and wipe it dry with a dry cloth. And the north is slightly better, if it is the south, the rainy season, then it is better not to scrape, let the masters stop for a few days! Haste makes waste.

It's hard to say if there's a problem. Ventilation is not ventilated, will there be convection, if there is such a condition, it can be scraped, provided that it has just started or has been scraped once, if it is scraped once, then it is necessary to see the first putty to dry before scraping the second time, so that it can be safe and secure.

In the event of a collision, the base layer, i.e. the plank, will be deformed, such as bending, and the rigid cohesive soil and large ones will crack and peel off from the plank. Therefore, when dealing with wooden walls, we generally do not approve of this approach. The best way to do this is with paint.

Putty is a rigid material. When the indoor temperature rises or falls, the change of the wood board is stronger than that of the putty, and for a long time, the putty will crack, and after cracking, air will enter, the adhesive will age, and the adhesion between the putty and the board will become smaller, and the putty layer will fall off after adding moisture changes and erosion.

The correct process is, return to the sand nemesis, plaster leveling, the whole house netting, scraping putty, brushing paint, if the requirements are high, the house is square, punching and dotting! The probability of peeling, bubbles, and cracks in the paint directly is too high, because there is too much sand on the wall of the rough room! And the poor level of mortar leveling will affect the effect of scraping putty, which requires every step of the process to be done.

Don't be in a hurry to move in the renovated house, after a few months of high temperature in the summer, the nail is volatilized, the effect is the best, pay attention to the window and balcony ventilation when moving in.

On cloudy days, moisture returns, causing the wall paint to peel off and become moldy or powdery, again threatening indoor air quality. It is best to scrape putty before painting, and open the windows for ventilation for more than a month, and even if you move in, you should buy some green plants that can purify the air. Hope it helps.

It is necessary to understand what is the use of scraping putty, only by understanding these, can we know the benefits of scraping putty, in addition, when scraping putty, there are many problems to pay attention to, and we need to understand it in detail.

It is not recommended to scrape putty on rainy days, because the air moisture is relatively large on rainy days, and the wall is more difficult to dry, and the putty is scraped on rainy days, and the moisture on the wall should be wiped clean first, and the wall should be kept dry as much as possible, and with the increase in indoor temperature, the moisture of the original undried material begins to evaporate, and the wall is likely to have problems such as "cracking".

It's true that if you scrape putty on a rainy day, it will make the house very wet, and it will dry slowly after scraping putty.

The construction temperature of scraping putty should be above 5 degrees Celsius, and it is not good if it is too cold.

The construction environment has always been a very important factor, if the ambient temperature is too low, it is easy to affect the dissolution of organic additives in the putty, if the additives can not be fully dissolved, or the dissolution speed is too slow, it will affect the film-forming quality and construction performance of the putty after scraping.

Of course, the environment is too hot and too dry, and putty construction is suitable for 5 -35 environments.

The batch scraping of putty should not be too thin or too thick. If it is too thin, the putty layer is prone to water loss too quickly, resulting in the putty chalking, which will eventually affect the effect of the coating. The thicker the putty layer is scraped, the greater its dry shrinkage strength and the easier it is to crack.

Therefore, the thickness of the batch scraping of a single putty is best between.

The wall is the basis of putty scraping, if there is floating ash or loose wall, it will cause the putty layer to be unable to form a firm bond with the wall, which is very easy to cause problems such as displacement and falling off of the putty layer.

If the putty can not be tightly attached to the wall, it will shrink and expand under the external force caused by temperature changes, humidity changes and other factors, which will cause the putty layer to crack.

After stirring, it is placed for a while to provide sufficient dissolution time for the ingredients in the putty, so as to ensure the construction performance of the putty and the quality of film formation in the later stage, and avoid the waste of additives.

When it's cold, you can also scrape putty. There are two types of putty, on-site blended and finished putty. on-site preparation of putty with glue, plaster; It can also be blended with color essence, white latex, large white powder, etc.

Putty drying time and temperature, humidity, air circulation is related, under normal circumstances, it can be dried in about 4 days outside the winter, if it is rainy, it will take about a week; Generally, the first plaster base should be dried slowly, a week's look, the second finished putty is about 4 days, and the third finished putty can be screened in about 2 days.

When it's cold, you can also scrape putty, but the effect is not too good.

1. Can you scrape putty in winter?

1. Scraping putty in winter can make the putty on the surface of the wall solidify quickly, reduce chalking and cracking, and speed up the drying time of paint and coating, and the film-forming effect is good. Secondly, it is conducive to the rapid volatilization of formaldehyde and reduces the residual amount of toxic substances in decoration materials. However, it should be noted that although the putty can be scraped in winter, the temperature is too low in winter, and the ventilation should be done at the appropriate time, otherwise any improper behavior will affect the final effect, so when scraping putty in winter, the room temperature should generally not be lower than 10.

2. Putty construction can be carried out in winter, putty powder contains a lot of chemicals, and scraping putty in winter can reduce the time for toxic gases to remain in the room. At the same time, after the construction is completed in the case of low temperature in winter, opening the window can make the putty on the wall dry faster, avoid the putty pulverization and cracking to a certain extent, and the film-forming effect will be better. Scrape putty in winter should not be too thick, and try not to use cement putty.

In winter, the indoor air is dry, and the water loss is fast, which is easy to cause hollowing, cracking, and uneven walls. The application should not be too thick during construction, and the next layer can be applied only after the paint has dried.

Second, the precautions for scraping putty.

1. When scraping putty, the base layer has strong absorption, and it should be closed with a primer before scraping and applying putty, so as to avoid the rubber in the putty being absorbed too much by the base layer and affecting the adhesion of the putty.

2. Master the inclination of the tool when scraping and applying, and use even force to ensure that the putty is full.

3. In order to avoid excessive shrinkage, cracking and falling off of the putty, do not be too thick at one time, and the thickness should be appropriate according to the characteristics of different putty.

4. Do not scrape back and forth too much, so as to avoid rolling, falling off or squeezing out the rubber in the putty, etc., and the sealing surface is not easy to dry.

5. According to the performance of the coating and the condition of the base layer, select the appropriate putty and scraping tools, when filling the holes and cracks of the base layer with a putty knife, press the blade with the index finger, and press the putty into the defect forcefully.

In winter, the wall can scrape putty, but there is a requirement for the temperature to make putty powder in winter, usually more than 5 degrees Celsius.

1. There are many additives in putty, which need to be dissolved at a certain temperature. If the temperature is too low, the dissolution rate of these additives will be very slow and cannot be fully dissolved, which will directly affect the speed and quality of putty film formation in the later stage.

2. Putty powder should not be used on the same construction surface with other putty, so as not to cause chemical reaction and color difference.

3. After the putty powder is adjusted into a paste, it should be used within 4-5 hours to avoid deterioration for too long. If the temperature is too low, the putty is easy to crack.

Extended Information: Precautions for scraping putty in winter:

1. Scrape putty evenly.

Before scraping putty in winter, the cracks in the base layer should be filled first, and the putty must be scraped evenly. Because the putty needs to be scraped in layers, if a certain layer is scraped too thickly, it will take a long time to dry, which will affect the construction of the next layer.

2. Maintain indoor temperature.

If the indoor temperature is too low during construction, it must be heated in time to increase the indoor temperature. Otherwise, the wall will dry quickly, so that the putty will soon appear hollowing and cracking.

When the indoor temperature is above five degrees, the putty can be scraped, if the freezing temperature is reached, the putty can not be scraped again, otherwise there will be freezing and cracking, when the temperature is low, the putty will dry slowly after scraping.

It depends on the level of indoor temperature, generally speaking, winter construction can make the wall surface putty quickly solidify, reduce chalking, cracking, but also speed up the drying time of paint and coating, and is conducive to the rapid volatilization of formaldehyde, but it should be noted that when the paint is painted in winter, the room temperature is generally not lower than 10. As long as you pay attention to the temperature, ventilation and application of added auxiliary materials, you can ensure the construction quality and original appearance of paints and coatings.
