What should I do if the putty powder is scraped and foamed? Under what circumstances does putty powd

If the putty powder foams during this process, you can gently scrape off the blistering area. Then apply a new layer of putty powder on it so that it will not foam again. The reason for the blistering may be related to the quality of the putty powder.

If the quality of putty powder is not particularly good, it is very easy to foam. If the wall is too rough during this process, the putty powder is also very prone to foaming. <>

I believe that in the process of decoration, you will also choose to apply some putty to the wall. Upstairs putty powder will make the whole room look cleaner, and it will also be more convenient for the next decoration work. However, in the process of applying putty powder, you will find that there will be foaming on the wall.

When this happens, the aesthetics of the wall will be particularly affected. At this time, you can use a tool to gently produce the blistering area. After shoveling off the blistering area, you can reapply the putty powder, so that the problem of blistering is solved.

Many people will wonder why there is foaming after applying putty powder, and the reason for this change is that the quality of putty powder is not particularly good. In the process of decoration, many people will choose to buy some cheap decoration materials, because everyone thinks that this will save some money. In fact, there are some cheap decoration materials, and its quality is not guaranteed, so in the process of use, putty powder is very prone to foaming.

Another biggest reason is that because the scene is too rough, you will find that if the wall is very rough, it is very easy to blister. <>

When you apply putty powder, you can clean the wall first, and at this time you can see if there are some potholes on the wall. If there are a lot of potholes, you can also choose to apply some cement to make the wall look smoother. In this way, it will save more time when applying putty powder, and it will not cause blistering on the wall.

You can also choose to use some tools to deal with these uneven areas. When applying putty powder, the technique is also very crucial, so you must find some reliable decoration team.

When decorating, there is no primer coating, there are fine cracks on the wall, and there is no filling and trowel treatment, and the putty is scraped directly on the wall, which is prone to blistering. After pressing a few more times, the bubbles will gradually disappear, the first time does not need to scrape so thick, the second time is thin to keep up, the speed of batch scraping should not be too fast, as long as you carefully master the scraping three or two times after you can find a way to deal with the bubble problem. Uneven stirring, after a period of construction, the foaming on the surface is mainly caused by uneven stirring, the slurry contains powdery particles that have not had time to dissolve, and a large amount of water is absorbed after construction, and swelling forms bubbles.

If the wall is too rough, it is best to level it with stucco plaster first, which can facilitate subsequent putty scraping. In addition, scraping putty also has high requirements for the humidity of the wall: too wet the wall will affect the strength of the putty slurry, and it is easy to dry out in the future.

The treatment method is to shovel off the blistering place with a shovel, and then clean the wall, do not leave debris and dust, and finally re-smooth it with putty powder. Before brushing the putty powder, the wall surface is not cleaned, and the putty powder will foam if there is dust and other debris, etc.

The putty powder is blistered because the proportion of water is not added appropriately, and there is a possibility that the wall is damp.

Scraping putty is also called scraping white, which is a necessary step for wall decoration and painting. After scraping the putty, the paint will be smoother and regular, and it can be well bonded to the wall. Scraping putty generally has to scrape about two layers, be sure to wait for it to dry completely before entering the next step, and if you find that the putty is blistering, you should also deal with it as soon as possible.

How to deal with the bubbles in the putty

1. When the putty is blistered in a large area, the small blisters can be crushed directly with a spatula, and then the blistered surface layer can be scraped again with a suitable putty.

2. After the putty is stirred evenly, it will stand for about 10 minutes, and then stir it again with an electric mixer before putting it on the wall.

3. When the second or subsequent surface layer blisters during construction, the bubbles should be crushed with a spatula before the blisters are eliminated to ensure that there are no bubbles on the putty surface.

4. For particularly rough walls, coarse putty is generally selected as the base material.

5. In the environment where the wall is too dry or windy and the sun is strong, first moisten the wall with clean water as much as possible, and then scrape the putty layer after the wall is waterless.

Does it matter if the putty blisters for the first time

Important, it is recommended to break the blistered surface and re-scrape the putty according to the situation.

Blistering putty is normal. The first putty generally has such bubbles, the master will clean up, and there will be no such bubbles to the second time, of course, in a normal order, the first putty can be dried on the second course. Generally speaking, most of the blistering is a rough wall, and the wall itself is not smooth, and there are a lot of small sand grains in it, so blistering will occur.

It may also be caused by poor ventilation in the house and the house is not dry.

What's going on with the big white bubbles

1. The substrate is too rough and the scraping speed is too fast.

2.The layer of putty is too thick to be applied at one time, more than 2mm.

3. The water content of the base layer is too high, and the density is too large or too small. Due to the abundant voids, and the putty has a high water content and is not breathable, the air is enclosed in the void cavity and is not easy to eliminate.

4. The surface blisters after a period of construction are mainly caused by uneven stirring. The slurry contains powdery particles that do not have time to dissolve. After construction, a large amount of water absorbs and expands to form cracks.

1. When the foundation of the wall is very dry and there is no floating ash, the blistering phenomenon can be removed by applying the interface agent. 2. You can buy some finished putty powder. When purchasing, you must observe carefully, some putty powder is not equipped with enough glue at all, or even there is no such ingredients at all, you must add some gum items, otherwise it is very difficult to construct it, and it is easy to blister and crack when it is cracked.

Related knowledge popularization: 1. When the wall drop is relatively large, first use stucco plaster to find the plane, and then slowly scrape the putty, the scraped putty can not be too thick, otherwise it is easy to blister. 2. Then remove the closed wall, as well as the area that is damp and alkaline.

Care must be exercised when operating. 3. When the putty is fully stirred, scrape it on the wall several times, and each time it must be compacted. By doing so, you can avoid blistering.

4. If there is a bubble for the first time, the bubble can be crushed, basically it will not affect the subsequent operation, if there is a large area of bubbles, you should use a shovel to directly crush the small bubble, and then scrape the blistered surface layer with new putty. 5. Remove the bubbles and dry them first, then fix them and re-polish the material on them.

Whether it is a self-built house in the countryside or a commercial house in the city, decoration is a particularly noteworthy issue. At this time, people will always fall into a tangled state, such as what material to choose, what style to install, and so on. Scraping white putty on the wall is not a new practice, but it is a step that almost all decorators do.

Even if it is wallpaper, it needs to be coated with putty. This improves the flatness of the wall and increases the adhesion of the glue. Therefore, putty is almost an indispensable process in decoration.

Anything can happen. When there are a lot of people working on something, problems are likely to arise. Of course, putty can't escape this law.

It has been said that when applying putty at home, the walls and ceiling are always blistered. They want to know how to cope. In fact, putty blistering is not a particularly uncommon problem, but it is not easy to deal with due to its complex causes.

In fact, the cause of the blistering is related to the construction crew, but the biggest reason is not the construction crew. At best, he was inexperienced, and the real cause of putty blistering was related to the underlying foundation, that is, there were hidden dangers when pouring concrete or building walls, which caused putty to blister. The construction personnel are inexperienced and do not know how to deal with these foaming problems.

There are three causes of blistering, two are related to the roof and one is related to the walls. The easiest place to blister is actually the roof. But many people will ignore the blister problem here because most people will use the ceiling again.

But the top plate is where putty foams most frequently. First, let's discuss wall foam. We know that the reason for the blistering of the walls is that the bottom is too rough and uneven, causing the air eye to blow the putty up.

At this point, we can flash the interface first. In fact, it is also possible to pass it directly with a plaster. The aim is to completely seal the gas inside so that it cannot be blown out.

Then apply putty on top of it, which can effectively solve this problem. However, roof blistering is handled differently. For example, the top plate is too smooth, which leads to weak adhesion, and the finished putty falls off and bubbles form in it.

At this time, how to improve its adhesion is the key. Therefore, we have to apply a layer of something first to improve the adhesion, which can be an interface agent. After the interface agent is dried, a smooth surface but with high adhesion is formed, because the interface agent is also known as a surface modifier, which can effectively improve the original properties of the surface.

At this point, it is best to apply putty.

There are many ways to scrape the putty powder and blister it, the first is to hang off the blistered putty layer, and then re-paint, and choose coarse putty as much as possible for the base; The second is to clean the base layer of the wall and apply an interface treatment agent at the same time, which can enhance the adhesion of the base layer and the putty layer, and it will not be easy to blister.

I think you can directly use a shovel to press the foaming area of putty powder, and then use a suitable putty to scrape the foaming surface; You can use plaster on the wall first, and then wipe it with putty powder, or spray a layer of interface agent on the wall to scrape the putty.

If the craftsmanship is not good, we must pay attention to the selection of putty powder and the concentration, so that we can use it better and choose the right tool for operation.

Because the putty is rich in pores and has a high water content, it is not breathable, and the air is sealed in the pores and is not easy to remove. The bursting and blistering of the surface after a period of construction is mainly caused by uneven stirring. The slurry contains powdery particles that cannot be dissolved in time.

After construction, it absorbs a large amount of water and expands, forming a burst. The lack of a construction timeline will cause the construction crew to ignore some small pinholes in the wall during construction, as well as some pinholes due to leveling when not extreme. If there is a large area of foam putty surface, scrape the small bubble mouth directly with a blade, and then scrape off the foam surface with a suitable putty.

In general, stir the putty well, let it stand for about 10 minutes, then mix it again with an electric mixer, and then place it on the wall. If there is blistering on the surface of the second or second layer of construction, the blistering should be broken with a scraper before removing the watermark to ensure that there are no bubbles on the surface of the putty. For particularly rough walls, coarse putty should be used as much as possible for the general primer.

In an environment where the wall is too dry or in strong wind and strong light, the wall may be soaked with clean water. After the wall has no open water, scrape the putty layer.

Try to level as much as possible, because the fine pinholes generated by the second layer will not affect the normal construction of the second layer, which is conducive to scraping.

The second and third layers of putty powder are leveled to reduce the generation of pinholes. The ratio of putty to water is very important. If it is adjusted too thinly, it will waste material and affect viscosity.

If it dries slowly, it can easily foam; If the adjustment is too dry, it is easy to be too thick and uneven. Now the most common water-resistant putty powder can be mixed directly with water, and the water-to-powder ratio is 2:1.

After adjustment, be sure to let it stand for about 15 minutes so that the putty powder is completely dissolved, so that there will be no clumping and foaming. If the wall is too rough, it is best to smooth it with plaster first, which can facilitate the subsequent scraping of putty. In addition, putty also has high requirements for wall humidity:

If the wall is too wet, it will affect the strength of the putty slurry, and it will be easy to dry and crack in the future; Due to the high humidity and airtightness of putty slurry, the air in the wet wall will be locked and it will easily bubble after drying.

In the process of decoration, if the putty powder is easy to foam, then it is likely that the ratio of putty powder and water is not fused correctly. It is necessary to re-fuse the putty powder.

You can put some water into the putty powder to evenly mix the putty powder, so that the problem of putty powder foaming can be improved.

Clean the surface in time, don't let the wall surface be too rough, brush a layer of interface agent, and then lay a layer of plaster.

Putty powder scrapes up and foams, what causes this? During construction, the base is too rough and has tiny holes, and the air in the holes bounces and forms bubbles when scraping. The moisture content of the base layer is high, and the putty carries too much water.

Some low-quality lime milk contains a large amount of quicklime, and after adding water, a violent exothermic reaction will occur, producing a large amount of gas and foam.

1.Putty powder scrapes up and foams, what causes this? During construction, the base is too rough and has tiny holes, and the air in the holes bounces and forms bubbles when scraping. Scrape too thick, and the air in the putty hole can't be squeezed out; The base layer is too dry, and the water absorption rate of construction is too high, resulting in an increase in bubbles; The selection of waterproof coatings with high sealing performance leads to impermeable bubbles in the base layer; air bubbles caused by high construction temperatures; Excessive cellulose addition.

The use of cellulose and rubber powder with high viscosity or easy air entrainment leads to strong film-forming putty, the gas of the base layer is sealed, and the bubbles cannot be discharged; Some low-quality lime milk contains a large amount of quicklime, and after adding water, a violent exothermic reaction will occur, producing a large amount of gas and foam.

2.The moisture content of the base layer is high, and the putty carries too much water. The ratio of putty powder to water is 1:

If you don't adjust the putty according to this ratio, add too much water, and the putty will blister after it is on the wall. Moreover, the base layer itself has moisture and is not breathable, causing the air to be sealed in the putty and will bubble.

Adjust the putty proportionally, and then mix the putty powder with an electric mixer. It should be noted that it is best to stir twice, 10 minutes apart, so that the putty powder can be stirred evenly.

3.The putty should not be scraped too thickly as the putty needs to be scraped three times. If it is thick every time, it will affect the final construction effect.

If the putty foams for the first time, use a shovel to crush the blistering area first, and then fill it with putty. If there is a large area of blistered putty noodles, directly use a spatula to crush the small bubble mouth, re-apply the appropriate putty, and blow up the blistered noodles. Putty powder scrapes up and foams, what causes this?

4.Generally, the putty powder is stirred evenly and let stand for about 10 minutes to allow all the ingredients to be fully moistened and dissolved. Mix with an electric mixer and place on the wall.

During the construction of putty, it should be repeatedly scraped and rolled on the wall, so that the putty is in full contact with the base layer, wetted, infiltrated and diffused, and bubbles of the putty layer appear on the second or last side of the construction. Before the watermark is removed, a scraper should be used for pressure defoaming to ensure that there are no bubbles on the surface of the putty.
