Diatom mud wall cracks what s going on, what is the treatment method?

Diatom mud wall cracks what's going on?What is the solution?

Putty scraping the wall can make the wall look softer and more delicate, that is, beautify and save materials. However, if the frankincense layer breaks, it is easy to cause a breakdown of the surface layer.

**Method: If the crack has penetrated into the layer of cement, you can also first use a sharp tool to enlarge the size of the crack with a screwdriver, rivet and polish the filled plaster, use mesh fabric or kraft paper and then align the putty level.

Mainly due to the quality of wall paint products and the wrong operation in the construction process of wall paint. If the temperature is too low, the film-forming temperature of the wall coating cannot be reached, and a continuous coating film cannot be formed, which will also cause the paint on the wall to crack.

Treatment: If it is only a crack in the surface paint film, you can use fine sandpaper to polish the crack, and you can choose the same color wall paint as you can repaint. In addition, many consumers have made every effort to choose a good painting when they buy paint, especially when they see a carton that says "crack resistant" on it, thinking that using this paint can prevent the wall from cracking the product.

It's not big. Gypsum cracks are divided into normal cracks and abnormal cracks. Normal cracks mainly refer to cracks in the plaster layer caused by the shrinkage of cement mortar. Abnormal cracks are mainly caused by insufficient materials or construction techniques. Normal cracking is difficult to avoid, but abnormal cracking can be avoided.

**Method: If vacuum cast in a large area in the plaster layer, the layer of the original plaster must be removed and the plaster layer of the cement mortar must be reworked, then leveled and painted according to the normal process.

The crackage of the seal is mainly caused by the joints between the wall cutting reinforced concrete and brick ceramite, reinforced concrete beams and ceramsite brick door compartments, separating the joints between the plasterboard and the original wall panels. Cracks in the office board are mainly due to the surrounding environment or external forces. Drywall, prefabricated partitions and prefabricated floor slabs will shrink and change position, which will result in joint cracks, usually vertical or horizontal.

Solution: It is recommended to repair the entire building after the deformation has stabilized, and the repair can be repeated in a short time.

Hope it will be useful to you.

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.

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.

The first thing to do is to figure out the cause of the cracking of the diatom mud wall, if the following 5 situations occur, please follow different methods to remedy!

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. Diatom mud cracking caused by cracking at the joint.

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 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. Diatom mud cracking 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.
