Is there any solution to the putty at home?

There is no good way but to scrape off and re-powder it.

If the powder loss is not serious.

The scraped putty will keep it for a long time without falling off.

The surface of the base layer is scraped putty.

The front must be firm and firm, and there should be no defects such as sanding, cracks, and looseness. If the wall is flat, it is recommended not to use putty, if the use of putty is easy to thin and should not be thickly brushed, the interior wall putty should not be softened and expanded by water, and must not be smeared with powder by hand.

In addition to being easy to approve and easy to polish, the requirements for putty should also have good strength and durability. For exterior walls, kitchens and bathrooms, putty is required to have better adhesion, bond durability and water resistance. After the putty dries, it should be sanded with sandpaper, and then the floating ash on the putty should be wiped off with a damp cloth, and the paint should be painted as soon as possible.

Precautions: 1. When preparing to paint the wall with latex paint.

When the wall is originally painted with lime or paint, the original wall must be removed first, and the putty must be scraped again before the rough brushing is carried out.

2. For customers who buy colored latex paint, they must be redeemed at one time when mixing latex paint with water, so as to prevent color difference and inconsistency when painting.

3. The quality of the roller brush is also the key to consider the quality of the putty. Therefore, the roller brush must be good, such as the hair quality and hair volume need to be moderate and uniform, after all, this is directly related to the effect of painting.

4. When painting, the ceiling should be brushed first and then the wall.

It can be applied directly with putty. As long as the substrate is dry and irritable, there is no strong wind, there is no problem, if there is a gypsum board joint or something, you need to use a cloth tape to paste the joint, there are relatively large gaps or pits, you need to use gypsum to level first, putty problems are generally because, the substrate is not dry, or the batch is too thick, or the wind is seen, or the window is too damp, etc. If so, the regular operation is to finish the putty, then hit the sandpaper, flatten, and then spray or roll latex paint.

Scraping putty is to pay attention to the following matters, and the scraped putty can be kept for a long time without falling off

1. Remove the spalling layer;

2. Polishing the old wall to increase the surface roughness, and then treat it with an interface agent (10% environmentally friendly glue);

3. Use degreasing and cleaning agent to remove the release agent or other grease components on the surface, and then apply putty;

4. Use two-component or special plywood putty for construction;

5. Marble, mosaic, ceramic tile and other exterior wall surfaces should be made with special ceramic tile renovation putty;

6. Use the putty within the shelf life.

The putty powder on the wall falls because the wall is affected by external factors, such as sun and wind, humidity and aging, etc., which causes the wall to expand and contract, and the putty powder is not firmly bonded to the wall and falls off. If not treated in time, it will not only affect the aesthetics of the wall, but also gradually damage the wall structure, thus affecting the overall quality and safety of the home.

In view of the problem of putty powder falling on the wall, we can take the following measures:

1.Clean the wall: First of all, you should remove all the putty powder that has fallen off, and use a broom or vacuum cleaner to clean the dust surface of the wall to remove loose dust and residual putty powder.

2.Repair the wall: For the wall that has fallen off badly, it is necessary to reapply new putty powder for repair. In the repair process, it should be carried out in strict accordance with the operation requirements of putty powder, so that it is completely combined with the wall to make the wall more flat.

3.Precautionary measures: In order to avoid wall putty powder from falling, we should take some precautions.

Before decorating the house, we can use roughening treatment to enhance the adhesion of the wall surface and avoid the putty powder from falling off; When using putty powder, you should pay attention to the choice of dilution ratio, not too much dilution, once the flexibility of putty powder deteriorates or the surface is unevenly dried, it will lead to putty powder easy to fall after construction.

The putty powder on the wall needs to be repaired in time, and preventive measures should be taken to avoid problems. If the problem is more serious, you can consider asking a professional decoration company to deal with it to avoid further quality problems on the wall.

When decorating, if you want to paint the wall, you must first scrape putty and fix the wall, which not only has the effect of leveling the wall, but also allows the wall paint to be firmly bonded to the wall. After we scrape the putty, we have to wait for the putty powder to dry and solidify before we can apply the wall paint. After the putty is dry, we can try to touch the wall with our hands, if there is no powder, it means that the putty is fine, otherwise it is best to solve the problem of powder loss and then move on to the next step, otherwise the wall paint will also appear in the future bulging, peeling and other situations.

If the putty layer is severely pulverized, it is recommended to remove the putty as a whole, brush the interface agent and then scrape the putty. If the powder loss is not serious, the surface can be masked by coating with PVA glue or styrene acrylic emulsion. After scraping the putty on the wall and drying it for a while, press and rub the wall with your fingers, and your hands will be covered with white powder, which indicates that the putty powder has no adhesive strength.

If the putty is very badly powdered, you can't paint the wall anymore in the future. Even if the wall paint is painted, the wall paint will bulge and peel off, etc.

1. Raw materials and their proportions. Insufficient addition or poor quality of cementitious materials such as lime calcium, cement, and gypsum. Cellulose quality is poor, the purity is low or the gel temperature is low, and the amount added is insufficient.

2.Construction issues. If the application is too thin, the mixing is not sufficient after adding water, and the effect of chemical additives is not sufficient.

3.Climatic factors. High temperature and dryness, strong light exposure, windy climate, easy to lose water too quickly.

4. The grass roots are damp or not firm.

5. The water absorption rate of the base layer is too high (the wall is too dry), and the putty drying speed is too fast.

6. The product has exceeded the shelf life, and the bonding strength has decreased sharply.

7. The product is stored improperly, and the adhesion decreases sharply after moisture absorption.

1. When polishing the surface layer of putty on the interior wall, it is necessary to master the appropriate polishing time. A good polishing period is to polish as soon as the watermark on the surface of the putty disappears. Practice has shown that veneers of 1-2 square meters should be flat or polished.

2. After the surface of the exterior wall putty is dry, it should be properly polished and sprinkled with water. The general maintenance is divided into more than two times. If necessary, use a clear closure primer mixed with water (1:5) as a second spray for better results.

3. The product must be used within the warranty period. If the warranty period is exceeded, a test scratch must be performed. After passing the inspection, the construction can be carried out.

4. The product must pay attention to waterproof treatment, should be stored in a cool and dry place, and ensure that the packaging is intact.

5. In summer or when there is high temperature and wind, the wall should be moistened with clean water first, and then putty should be applied. After there is no clear water on the surface of the wall, putty can be applied.

Powder removal solution 1, the surface layer of the interior wall putty should be polished to master the appropriate polishing time, the best time for polishing is to polish the putty surface after the watermark disappears. 2. When scraping the putty on the interior wall, it is best to control the thickness between 1-2mm, which can effectively avoid the depowdering caused by too thin thickness and the cracking of putty caused by too thick thickness. 3. The product must be used within the shelf life, if it exceeds the shelf life, it must be scraped, and then constructed after passing the inspection.

4. The product must pay attention to waterproof treatment, should be stored in a cool and dry place, and ensure that the package is intact. 5. In summer or under high temperature and strong wind conditions, it is best to wet the wall with water before scraping putty, and the putty can be scraped in batches after there is no open water on the surface of the wall.

What is the reason for putty to drop powder on the wall? What is the reason for putty to drop powder on the wall? Now start learning to tell you the reason why putty batches the wall is powdered!

What is the reason for putty batch wall powder 1Putty adhesion is insufficient. It leads to low bonding strength or small addition amount of putty glue powder, especially for interior wall putty, the size of the bonding strength, depowdering and not depowdering, and non-depowdering has nothing to do with the quality of putty glue powder and the large amount of putty added.

2.The quality of gray calcium is very important. Gray calcium contains a large number of impurities, or the ratio of bay calcium powder and Ca2 in gray calcium is not appropriate.

3.The recipe is not reasonable. The amount of talcum powder, lime calcium powder or any other product is not reasonable.

4.The issue of material selection and structure is very important in putty formulation. For example, although it is not waterproof putty, although it is expensive, it has no effect on fillers such as double fly powder, talcum powder, wollastonite powder, etc.

If only fillers such as Yinfei powder, talcum powder, and wollastonite powder are used, it will lead to depowdering, while low Yinfei powder and low-sound Yinming fans will not cause depowdering, but Yinfei powder and white cement cannot be used as exterior wall putty, because they react when they encounter gray calcium powder and white cement. These can cause depowderingThere are also polyacrylamide added to gray calcium powder, and white cement is used as a waterproof coating, which will also lead to oil depowdering.

5.Errors in the production process lead to greasy depowdering. If the mixing mixer does not have a cleaning function and additional powder remains, the head flour in the ordinary putty will correspond to the gray calcium powder in the waterproof putty, and the head flour in the interior wall putty will be the opposite of the white cement in the exterior wall putty, resulting in depowdering.

6.The different qualities of the filler can also easily lead to depowdering. The more filler material used for interior and exterior wall putty, the easier it is to depowder.

However, the interior wall putty powder in Chongqing and Chengdu contains different calcium powders, and the different pH levels will also lead to putty depowdering. For example, Chongqing and Chengdu interior wall putty powder use the same paint glue powder, but talcum powder and heavy calcium powder are different. It is not depowdered in Chongqing, depowdered in Chengdu, not depowdered in Henan and Northeast China, and depowdered in other regions.

7.Weather reasons are also a reason for the depowdering of putty on interior and exterior walls, such as the dry climate and good ventilation in some arid areas in the north, and the putty veneer is quickly formed and does not depowder. But not in the south, especially in the south there is rainy weather, long-term humidity, putty blending is not good, and it will also be depowdered, so these areas are suitable for inorganic binders such as gray calcium powder and white cement.

Impure lime calcium powder and white cement are impure, there are many gray calcium powders on the market, and white cement is not pure. Because of the large use of these inorganic adhesives, the waterproof paste for interior and exterior walls is definitely not waterproof. 9.

In summer, in high-temperature and ventilated places such as the windows in front of the high-rise doors of the building, the initial setting time of gray calcium powder and cement is not enough, and the water has been lost, there is no maintenance, and the powder is seriously depowdered.
