Diatom mud has just been completed and does not fall off the powder, what is the reason for the powd

The reasons that affect the powder loss of diatom mud wall can be analyzed from the following:

1. Before construction: diatom mud should be mixed with water before painting, if it is mixed with too much water, diatom mud will not only not cover the wall base, but also will appear to fall powder. Qualified products will provide a clear ratio of water, which is theoretically the most scientific.

However, consumers do not need to demand that workers mix water in strict accordance with the proportion, and the experience of the construction personnel themselves is worth learning, and on this basis, appropriate adjustments can be made for different environments. However, it is necessary to pay attention to the control amplitude, if you mix too much water, there will be powder loss, cracks and other phenomena.

2. During construction: confirm that the base of the wall has been treated, and the base is completely dry without hollowing. In addition, during construction, it should be noted that the main material of diatom mud should be flattened as much as possible during the first construction, and then textured to avoid the phenomenon of powder loss caused by the loosening of the wall caused by the large pores of the main material of diatom mud in the wall.

3. After the diatom mud construction surface is dry, a batch knife or fine sandpaper should be slightly sanded to remove the floating and sedimentary objects on the surface and the excess unrecovered sand, etc., and remove the surface dust with a brush or towel.

As long as the above points are achieved, the diatom mud with non-product quality problems will not fall off.

Generally, there are two reasons, the first is that the mix ratio did not come in accordance with the regulations, and the second is that there are some problems with the construction process, so it is best to ask the diatom mud master to take a look.

Diatom mud has green, environmental protection, and strong artistic appeal, which can make the home appear more comfortable and beautiful, so many owners will choose diatom line mud when decorating the wall of the house. However, some people report that the diatom mud wall that has just been painted in the new house has fallen powder, so what is the reason for the diatom mud powder? How to deal with the powder off the diatom mud wall?

Next, we will introduce the solution to diatom mud powdering.

What is the cause of diatom mud powder?

1. Powder loss caused by too dry wall.

Nowadays, many construction walls are too dry, and construction technicians directly carry out construction in a hurry, resulting in powder loss after construction.

2. Powder loss caused by spraying too thin.

When spraying, if the diatom mud is sprayed too thinly, it will cause the diatom mud to lose powder.

3. Improper mixing with water.

If it is over-diluted, the adhesion of diatom mud itself will be affected, resulting in its inability to be as strong as some materials with more glue content, which will cause the diatom mud wall to fall powder.

4. Damage caused by light collection.

Some textures and processes (such as: diatom mud bomb coating) need to be treated when the diatom mud finish is semi-dry, if the timing or technique is not properly grasped, it is easy to leave burr stubble, and the specific surface area of these parts is larger, so it is easier to quickly lose water and dry, resulting in chalking.

How to deal with the powder off the diatom mud wall?

1. If the quality of diatom mud is not up to standard, the phenomenon of powder loss will occur. At this time, it is necessary to go to the brand's store to buy diatom mud, so that when purchasing, the product will not be unqualified. And after use, there will be no powder loss.

2. If the diatom mud is not mixed with water during construction, the powder will fall. At this time, it is necessary to find an experienced construction master to operate, and when operating, it must be in strict accordance with the specified standards to mix water. In addition, it is necessary to adjust the temperature and water quality conditions of the surrounding area at any time.

3. If the diatom mud is powdered because the light collection is destroyed, then wait for the diatom mud wall to be dry, and let the construction personnel clean the edge position and floating ash position on the wall with sandpaper or soft rag, and then collect the light. And when collecting light, it should be adjusted according to the situation of the wall at any time.

Generally speaking, the causes of diatom mud wall powder include the wall is too dry, sprayed too thin, improper mixing of water and damage caused by light collection, we need to choose the treatment method according to the specific reasons, in order to ensure the standardization of diatom mud wall construction, we had better find professional workers to operate, which can avoid a lot of unnecessary trouble.

Hello there is an easy way to test :

Seven days after the diatom mud is dried on the wall, touch the wall with the palm of your hand. Note: Do not press too hard, use your wrist as the axis to rotate the palm of your hand about 45 degrees, once is enough.

At this time, if more than 70% of the area in contact between the palm and the wall has dust, this situation can be judged as powder loss, otherwise, it is not powder loss.

Diatom mud is a function-based material, if it is treated like cement, it is obviously unrealistic, some people will use their fingers to rub hard at several points repeatedly, which will only destroy the surface structure of diatom mud, and then cause the wall that does not fall off the powder may also lose powder.

If it's diatom mud, it's okay, but the powder may be:

No thorough drying: It takes 1-3 days to dry thoroughly, depending on the weather, the solution is to wait for drying No light: The texture without light will lose powder slightly, you can wait for thorough drying and brush the surface of diatom mud with a brush, and then the powder will basically not happen.

Artificially accelerated drying in the drying process: for example, now in winter, some customers use floor heating to accelerate drying, which will cause powder loss in serious cases, it is recommended to stop these artificial operations, you can open the window for ventilation, but try to let it dry naturally.

If it is a problem of diatom mud, then there is no solution to this question, so try to choose a good diatom mud.

The following three kinds of improper construction will cause powder loss:

1) Dry environment. Including the wall, the ground, and the air is dry, the diatom mud itself has a strong ability to absorb and release moisture, and the water loss rate is too fast after being put on the wall, resulting in rapid pulverization of the surface.

2) Improper mixing with water. In particular, when the excessive amount of water is used in a near-liquid state, the diatom mud is mainly inorganic materials, and after being over-diluted, it cannot have good adhesion to some materials with more glue, which leads to a decrease in the overall bonding strength and causes the surface to fall off.

3) Compression damage. Some textures need to be pressed when the surface of diatom mud is semi-dry, and if the timing or technique is not appropriate, it is easy to leave burr stubble, and the specific surface area of these parts is larger, which is more likely to lose water and dry quickly, resulting in chalking.

Prevention and Solution:

1) Dry environment. Before the construction of diatom mud, we must do a good job of water retention for the environment. The wall should be kept as moist as possible, and if possible, you can roll water on the wall first.

During the construction period, do not open the windows for ventilation or direct sunlight in order to catch up with the construction period, and let the diatom mud dry naturally. If the air and the ground are dry, you can sprinkle more water on the ground to increase the humidity of the air. If you find that the powder may fall due to the dry environment, you should stop work carefully or immediately rework on the premise of doing a good job of water retention.

2) Improper mixing with water. Although there are many types of diatom mud products, and the proportion of different diatom mud to water may also be different, in most cases, there is no need to be too careful about what proportion to use to mix water, because different temperature, humidity, and water quality will have a certain impact on the proportion of water. In actual operation, as long as it is guaranteed to be pasted after mixing with water, it is advisable to use a shovel to stir up the stirred diatom mud and put it on the side for 1 second before dripping back into the barrel.

3) Compression damage. This is the situation that will only occur when some individual texture construction is carried out, although this kind of powder is common but in fact it is not terrible, as long as the material is completely dry with a brush or wet rag to clean the edge and surface of the floating ash thoroughly, there will be no more powder loss in the future.

It may be a fake diatom mud, and the real diatom mud should not appear like this, it is recommended to contact your seller and the construction party.

Fake diatom mud is very harmful, not only unenvironmentally friendly. The workability is very poor, and the surface texture effect cannot be guaranteed. Strength is a big problem, it is very easy to detach and crack.

At the same time, the color changes color with oxidation. Those informal companies are certainly not able to give customers long-term quality assurance. Regular diatom mud can only be made of natural stone powder as a pigment and will never change color.

You can see it in the saturation of the colors. If it's bright, it's definitely a harmful color. Regular diatom mud is low saturation.

The surface effect is definitely a soft, slow-reflecting light. As for those who have to roll toning paint on the surface, they are fake, the cost of that kind is only ten yuan, and they will charge you at least dozens or hundreds. It is conceivable that the so-called diatom mud of dozens of dollars per square meter is expensive or cheap?

How much powder is good, more glue naturally does not fall, diatomaceous earth is not sticky.

In addition to the quality of the product itself, there are also certain reasons for the construction. You can find out what the reputation of the brand you are making is, if the general reputation is not bad, then you have to see if you have purchased fake and shoddy products or improper construction.

Find a business, find a business. Defend your legitimate rights. In addition, depowdering can also be caused by improper construction. But whether it is a matter of materials or construction, it should be a problem for businesses and enterprises.

It must be a shoddy product, and good diatom mud will not lose powder.
