1. Chisel the cracked wall base into a "U" shape, and the spacing of the "U" groove is greater than 20cm, and the chiseled base is chiseled, and then the steel wire mesh is hung. 2. After the wall substrate is cleaned, a layer of good cloth, kraft paper or newspaper is pasted on the wall, and the tension of the fiber is used to ensure the integrity of the latex paint film. This method is relatively simple and easy, but the results are modest.

3. Remove the insulation board on the surface of the wall, or remove the cement wall, install a layer of gypsum board or "five-centiboard" outside the insulation layer, and then make latex paint on it.

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

1. Glue leakage filling method. First of all, clean the roof (limescale, garbage, dust, etc.) within the area to be filled. Then use a sharp-nosed steel chisel to open a 1 2 cm "V" shaped groove from end to end, the groove is 1 2 cm deep, and remove the dust in the trench (with a pump or air gun).

Then the waterproof glue A and B components 1 1 are evenly adjusted and brushed 2-3 times and allowed to dry. Then use 1 1 cement mortar (according to 5-20% of the cement input, add waterproof glue and fill the groove after mixing thoroughly. Finally, use a steel spatula to scrape the surface flat and make it sticky, let it dry naturally for 24 hours, and then soak in water.

2. Cement mortar repair method. First, 10 cm is cut on both sides of the crack, making it 20 cm wide. Length:

It is 10 cm longer than the ends of the crack, for a total length of 20 cm. Depth: This is the thickness of the mortar layer.

After opening, clean the base surface, there can be no water and no dust. It must be clean and there is no moisture! Then apply 911 polyurethane and brush one piece vigorously on the substrate.

After drying the next day, spread a layer of imitation cloth, and then apply a second layer, which requires that it be evenly painted, and sprinkle sand on top after application. The final step is to repair with cement mortar. This method can achieve the effect of filling the gap in 10 years.

1. There are many reasons for cracks in the roof of buildings, so we must first solve them according to the causes of cracks.

2. If it is a crack caused by the sun, then buy glue to make up for it, and then pay attention to shading the building when the sun is strong.

3. If the cracks are caused by the poor roof material of the building, it is a big problem, please ask a professional person to repair the roof of the building.

4. If the cracks on the roof of the building are caused by water accumulation in rainy days, then pay attention to timely drainage after the rain.

5. The material of the roof of the building is an important reason for the cracking of the roof of the building, so the use of materials must be considered when making the roof of the building to prevent the roof of the building from cracking.

6. The sunlight is too strong in summer, so it is recommended to pour water on the roof of the building at night in summer to prevent cracking.

1. Pressure grouting method: the air compressor will pour the adhesive into the cracks on the roof wall and re-bond the cracked walls together. 2. External force repair method:

Open the cracks in the original roof wall and repair them with elastic putty, or use a good cloth to fix them. 3. Go to the market to buy some linen for paint, paste the linen with white glue to the cracks on the roof, and then apply cement paint after drying. 4. Large area of roof wall cracks, make a "U" for the cracked roof wall base"shape, the substrate is repaired, and finally the wire mesh is hung.

You can see if the latex paint on the wall is cracked.

If not, if there is a crack in the wall, don't stop it, you can contact the relevant departments to see.

If there are obvious cracks in the roof of your house, you must repair it, otherwise it may affect safety or leakage.

Just look at whether the ground on which the house is built is on the ground, and if it is not on the ground, the house may not be able to live in because the ground has collapsed.

1. Surface repair method. This method is suitable for narrow joints, used to restore the surface beauty of the component and improve the durability of the use, commonly used is to lay film materials along the surface of concrete cracks, generally can be used epoxy resin or resin impregnated glass cloth.

2. Filling method. When the crack is wide, a V-shaped or U-shaped groove can be chiseled along the surface of the cracked concrete, and the resin mortar material can be used to fill it, and materials such as cement mortar or asphalt can also be used.

3. Injection method. When the crack width is small and deep, the repair method of injecting the repair material into the concrete can be adopted, firstly, the crack is provided with an injection pipe, and the other parts are sealed with surface treatment, and the material is injected with low-viscosity epoxy resin, and the repair is injected with an electric pump or a manual pump. If the crack affects the safety of the structure, the structure should be reinforced.

1. Latex paint cracks: If the paint film on the surface is cracked, use fine sandpaper to polish the cracks off, and then repaint with latex paint.

2. Structural cracks: The expansion joints between the structural wall and the brick wall will extend to the surface of the wall, and this crack is also a crack formed by latex paint.

3. Cracking of the putty layer: This crack is the slightest crack, which is caused by the putty layer being too thick or too thin. Just add a layer of putty.

What are the causes of cracks in the house.

1. Housing cracks can be divided into wall base cracking, plastering layer cracking, putty cracking, decorative layer cracking, etc., the reasons for cracking in different parts are different, such as wall base cracking, it may be because the construction personnel do not follow the requirements of reinforcement, vibration, mold removal, etc., or in the construction process of concrete components, the steel bars and concrete used do not meet the design requirements, etc.

2. The cracking of the wall decorative layer, such as the cracking of latex paint, may be caused by the lack of base treatment, such as the cracks of the wall base layer are not repaired. If we start construction before the previous base layer is dry, or the coating is too thick when the paint is applied, or the correct way to dry the latex paint wall, etc., it will lead to cracking of the latex paint wall.

What to do if the house cracks?

1. It is difficult to repair the cracks caused by temperature changes, but there will be no danger such as the collapse of the house. In order to avoid the premature tremor of this crack, it is necessary to solve the problem by solving the line expansion difference between the roof and the brick wall. Generally, the common method is to do a good job of roof insulation.

2. Due to the cracks caused by the insufficient stiffness of the masonry, the brick wall will bend in the plane, and at the midpoint of the bending length, there are often horizontal cracks. In this case, reinforcement measures should be taken. Pure cement slurry can be injected into the cracks by pressure grouting, and then methods such as adding pilasters or reinforcing the walls between windows can be adopted.

3. Due to the cracks caused by the insufficient strength of the masonry, the wall with such cracks is in danger of collapsing. Reinforcement measures are taken, generally by adding pilasters or using steel structure reinforcement.

4. Due to the uneven settlement of the foundation, the cracks in the brick wall are located in a different direction than the position of the cracks caused by the lack of strength and stiffness of the wall column. That is to say, the cracks caused by the uneven subsidence of the foundation do not cause the strength or stiffness of the wall columns, and are repaired with cement mortar after the settlement is stabilized.

5. If the stiffness and strength of the wall column components and the house structure are sufficient, then the wall cracks caused by the uneven sinking of the foundation do not need to be reinforced and reinforced, as long as the cracks are repaired.

1. It is dangerous to destroy the house before the roof cracks.

2. If there are cracks in the roof, it is generally caused by the destruction of the load-bearing wall.

3. The load-bearing wall is a wall that supports the weight of the upper floor, so when the cracks in this case appear, the relatively light impact will affect the service life of the building, and the serious situation may lead to the collapse of the building.
