If there are small cracks in the diatom mud wall, how can they be repaired?

1. If the damaged area of the diatom mud wall is very small, you can directly prepare the diatom mud of this color for repair, that is, DIY repair, there will be a small color difference, but it will not affect the appearance.

Second, if the damaged area of the wall is relatively large, it may be necessary to redo the whole wall, compared with latex paint and wallpaper, diatom mud construction is relatively simple, do not need to deal with the wall like wallpaper, as long as the original diatom mud wall is smoothed and covered, and then redone.

3. Make a pattern on the damaged area. If you don't want to recreate the wall, you can use the "art treatment method" to make a diatom mud drawing on the damaged area. Diatom mud can be used to make a lot of artistic patterns, which can not only decorate the wall but also cover the damage.

It can be repaired or repainted by DIY.

If the damage area of the diatom mud wall is relatively small, then you can prepare a diatom mud paint of the same color as the wall, and then apply it directly to the damaged area to repair it. If the damage area of the diatom mud wall is relatively large, then you should find a professional construction personnel to help repair it.

Under normal circumstances, there will be no cracks in the diatom mud wall. If there are cracks in the diatom mud, then it is necessary to check the base layer of the wall in detail.

If the damaged area of the wall is relatively large, it may be necessary to redo the whole wall, compared to latex paint and wallpaper, the construction of diatom mud is relatively simple, and there is no need to deal with the wall like wallpaper, as long as the original diatom mud wall is smoothed and covered, and then redone.

To achieve this effect, a spray gun is used, and the construction process is called "bullet coating".

In this case, it is necessary to use putty (similar to the color of the wall) putty to fill the pits, and then smear the diatom mud of the same color as the wall.

Causes of cracks in diatom mud walls: because the solid layer of the wall itself cracks will cause cracks on the surface wall, and the wall itself has gaps, and no appropriate treatment is adopted in the later decoration process; There were no cracks in the original wall during the decoration, but in the later stage, there were gaps due to uneven foundation sinking and large temperature changes; This type of gap is usually very wide and the crack is very long. When encountering this situation, effective measures should be taken depending on the size of the crack.

If the crack is wide, it cannot be repaired, but can be repaired or repainted after the wall is stabilized.

Cracking at the bottom layer of the wall joint will cause the wall surface to show gaps. The cracking at the interface first occurs at the interface between the reinforced concrete shear wall and the block brick, the interface between the reinforced concrete beam and the material or block brick, the construction door leaf of the later masonry, and the interface between the slatted partition wall and the original wall. The fundamental reason for the cracking at the interface is that it is harmed by the surrounding environment or external forces, and the gypsum board, prefabricated partition board and prefabricated floor slab will show a reduced transformation, resulting in cracks at the interface.

Treatment method: The crack on the surface of the wall caused by the cracking of the silicon bath coating is usually caused by the unqualified quality of the silicon bath and the improper actual operation of the diatom mud construction. It's just the cracking of the surface silicon bath, polish the crack with sandpaper, choose the same color silicon bath, and brush it again.

Therefore, according to the silicon bath purchased by the regular platform and the maintenance of normal temperature and humidity in the room, as well as its standard construction technology, the formation of gaps can be avoided.

Wall scraping putty powder can make the wall more moist and delicate, and the flatness is far more than that of the cement wall, in addition to saving some architectural coatings. Cracks in the putty layer can also cause cracks on the surface. Therefore, it is necessary to pay attention to avoid cracks in the putty layer during construction.

If the gap has already been deep in the putty layer, you can directly use a gray knife and other tools to expand the gap to the size of a screwdriver, and then introduce caulking gypsum and polish the ground leveling, paste the alkali-resistant grid cloth and use the interior wall putty powder to carry out ground leveling, and finally brush the silicon bath according to the normal process.

The cause of diatom mud cracks may be that the air humidity is too high, and the structure swells to produce cracks due to excessive moisture inhalation.

It is possible that there are cracks in the original sound in the front, and the appropriate treatment method was not taken during the later construction, so it led to the cracking of the diatom mud wall. In this case, it is necessary to repair the cracks in the original wall first, and then reuse diatom mud to decorate the wall.

It may be caused by gout, or it may be caused by the material, and it needs to be solved again, and if the gap is not particularly large, it can be filled.

1.Cracking of the wall structure leads to cracking of diatom mud.

Cracks in the structural layer of the wall itself will cause cracks in the exterior wall. This is divided into two situations: one is that there are cracks in the wall itself, and the appropriate treatment method is not taken in the later decoration process; the other is that there are no cracks in the original wall during decoration, but cracks occur in the later stage due to uneven foundation sinking and large temperature changes; This type of crack is usually very wide and long.

In this case, measures should be taken depending on the size of the crack. Cracks that are wide cannot be repaired, and can only be repaired or repainted after the wall has stabilized.

2.Cracking of diatom mud caused by cracking of the joints.

Cracks in the bottom layer of wall joints can cause cracks in the surface of the wall. The cracking of the joint first occurs at the joint between the reinforced concrete shear wall and the block, the joint between the reinforced concrete beam and the plate or block, the construction door opening of the post-masonry, and the joint between the slatted partition wall and the original wall. Cracks at joints are mainly due to the shortening of gypsum boards, prefabricated partition panels and prefabricated floor slabs due to the influence of the surrounding environment or external forces, resulting in cracks in joints.

In the face of this kind of problem, it should be repaired after the deformation of the whole building tends to be stable, and the repair in a short period of time is prone to recurrence. When the surface cracking of diatom mud is due to this reason, the main reason is that the gaps are not treated well; The walls are not protected against cracking to prevent joints.

3.Diatom mud cracking caused by cracking of the putty layer.

Wall putty can make the wall more lubricated and delicate, and the flatness is much higher than that of the cement wall, so that the wall coating construction effect is better, and at the same time, it also saves the amount of surface coating materials. If the putty layer cracks, it will directly lead to the cracking of the surface layer. Therefore, attention should be paid to the construction to prevent cracks in the putty layer.

The cracking of the putty layer is often related to the insufficient bonding strength of the putty and the lack of anti-cracking measures. The decorative cracking of the diatom mud caused by this reason cannot be repaired, so the quality of the putty layer is very important.

4.Cracking of diatom mud caused by cracking of the plastering layer.

The cracks in the plastering layer of the wall are divided into normal and abnormal: normal cracking mainly refers to the cracks in the plastering layer caused by the shrinkage of cement mortar; The abnormal situation is caused by improper construction technology. It must be treated well before the construction of diatom mud, otherwise it will not be repaired.

If there is a large area of hollowing in the plastering layer, the original plastering layer should be knocked out, the plastering layer of cement mortar should be redone, and the diatom mud should be brushed according to the normal process after leveling.

5.Cracking of the surface layer of diatom mud.

The main reasons for this problem are the poor quality of diatom mud products and the improper operation of diatom mud construction process. If only the surface of the diatom mud is cracked, use fine sandpaper to polish the cracks off, and then choose the same color diatom mud to repaint.

This situation depends on whether it is a regular crack or a chaotic crack. If it is a regular straight crack or transverse crack, it is most likely that the stucco at the junction of the brick wall and the shear wall of the wall has not been treated well, and it has nothing to do with the paint base and diatom mud. If it is a messy crack, then there is a problem with the stucco layer, the diatom mud base, or one of the processes in the diatom mud.

With the improvement of the quality of life, we pay more and more attention to formaldehyde in decorative materials and furniture in the decoration process. For the sake of the health of the family, many people choose to directly avoid latex paint and wallpaper when choosing decorative materials. Diatomaceous earth materials are more environmentally friendly to construction.

Although the material diatom mud and paint and wallpaper latex have a lower content of formaldehyde and the living environment of the beautiful material diatom mud, there are also advantagesHow to quickly repair the cracks in the diatom mud wall

Solution: If the crack has penetrated into the layer of cement, a knife and other tools can be used to first amplify the crack similar to the size of a screwdriver, then inject plaster polishing and polishing, leveling powder filler, and then homogenize putty dust to complete the process by brushing diatomaceous earth.

1.If the wall is built again, the new wall is different from the previous wall, due to building materials, construction time, construction techniques, etc., and the seals usually have cracks that will be tested for cracks.

2.Splicing walls, such as wood frame stitching and cabinet wallsHow to quickly repair the cracks in the diatom mud wallceiling and wall junctions. Due to the use of different materials in different layers of the alkali, the binding capacity is poor, cracks are easily generated in joints and are necessary for crack prevention**.

3.Protects the base layer of the wall from cracking. Paste the necessary materials of good fabric, and mesh in the walls to cloth the mesh in the cracks, seal the wall cavity and wall load, and plasterboard boards.

4.Use fine sandpaper to sand the small cracks on the surface of the wall and repaint them to repair.

Cracks in the walls penetrate the putty layer. How to quickly repair the cracks in the diatom mud wallYou can use a sharp tool to enlarge the crack size of a screwdriver, have caulking and polishing to fill, wear a good mesh fabric or kraft paper with putty leveling and final paint according to the normal process.

6.If the plaster layer has a large area of hollowing, the original stucco layer must be removed and the cement mortar layer must be rebuilt. After leveling with putty, apply the coat according to the normal process.

7.After finishing the wall, it must be dried naturally. The temperature and humidity of the room must be kept stable. After the surface is dry and film-formed, it can be applied twice.

8.Cracks in the walls may form during project construction, or they may be caused by improper maintenance in the future. Once the construction of the wall is completed, attention must be paid to maintenance.

What should I do if the diatom mud wall cracks? Some houses will crack after long-term use, and wall cracking is a headache, if not treated properly, it will cause large areas of cracks, therefore, cracks should be repaired as soon as possible.

1. How to repair wall cracks:

1。The paint layer on the surface of the wall is broken quietly: use fine sandpaper to polish the cracks, then clean and repair them, and then use the same paint brush as the wall; Secondly, 2.

Cracks in the wall structure layer: these cracks are difficult to repair, and should be repaired by professional building structure personnel; It's a great way to do it.

3。Plastering layer cracks: If the crack area is small, repair it with a good cloth. If there is a large area of cracks, the plastering layer should be knocked out first, and then leveled before painting.

4。Temperature-induced cracks are basically not insulation. What should I do if the diatom mud wall cracks? As long as the temperature of the surface layer is well controlled and the insulation layer is done, the wall cracks can be effectively prevented.

5。During the stable settlement of the building, the cracks caused by the settlement pull can be repaired by cement grouting, that is, the developer must carry out ** at the beginning of construction. Because the sedimentation period is a process, it can be kept an eye on all the time.

When the settlement is uneven, it can be dealt with in time.

6。Structural cracks are caused by insufficient bearing capacity. The bearing capacity of the wall can be increased by adding reinforcement, and the width of the wall can also be increased for protection to ensure that the wall does not crack.

2. What is the cause of wall cracking?

1。Temperature difference cracks, which usually occur at the junction of different building materials, such as cracks between load-bearing walls and rear partition walls;

2。The wall cracking caused by the subsidence of the building will have a certain settlement period after the building is completed. What should I do if the diatom mud wall cracks? If the settlement of the building is uneven, the tensile force is greater than that of the wall, and cracks will occur;

3。Cracks in the wall structure are caused by a long period of time. Insufficient bearing capacity can also lead to cracking of the wall.

4。Due to the incorrect ratio of cement to yellow sand in the wall coating, cracks in the cement coating layer may cause cracks in the latex paint.

5。What should I do if the diatom mud wall cracks? Cracking of the putty layer is generally caused by the putty layer being too thin.

First, how to repair the damage of the silicone mud wall? If the damage surface is small, the intact surface can be covered and protected with a film; Correct.

After that, choose a sub-flat depression with a similar color; Then adjust the color one.

diatom mud; Finally, it is repaired with a bullet coater. If the damage surface is more.

Large, you can first smooth the old wall and then refresh the diatom mud, or directly root.

According to the destruction surface to do graphic covering, but because of the complexity of the operation, you can find professionals.

Work. 1. Because it is not easy to absorb dust, debris and other substances after brushing diatom mud.

quality, so it is relatively simple to clean it, directly with chicken feathers off.

Sub-cleaning is fine, and there is no need to wipe it down from time to time. This.

Outside, although it can absorb water, it should be avoided when cleaning.

Scrub with water, otherwise it is easy to cause some filling mixtures to form after encountering water.

mud, which affects the overall appearance.

2. If the wall is polluted inadvertently in life, such as fingerprints and handwriting.

etc., you can use an eraser to deal with, here you need to pay attention to the eraser to choose.

Clean, because the black paint eraser is easy to leave marks when wiped away.

If the marks are deeper, you can try sanding them off with sandpaper, but by all means.

Be careful, however, the material itself is not easily destroyed, so.

When the scope of damage is too large, it is better to ask a professional person to come to deal with it.

3. If you accidentally splash colored liquid on the wall and leave traces in your life.

For example, coffee, juice, etc., at this time, it should be wiped off with paper in time to prevent the liquid.

The body flows to the inside, and the shallower ones can be treated with bleach. If the mark is far away.

If it is very deep and large, you can use the same color material after drying.
