What are the tips for wall plastering? Wall plastering method steps

Wall plastering is a step to be done in decoration, it can be said that the basis of wall decoration is the step of wall plastering, if the operation is not good enough, it is easy to lead to cracks and other problems on the wall, so what needs to be paid attention to in this step of wall plastering? Let's take a look at the correct way to plaster the wall.

The right way to plaster the walls.

1.Grassroots cleanup.

Before plastering the wall, it is necessary to do a thorough cleaning of the wall so that the wall is free of floating dust, granular debris, oil stains, residual mortar and other pollutants. If the wall is not full, then the defective areas need to be repaired.

2.The walls are moist.

After the wall is cleaned, in order to ensure the wetness of the wall, it can be watered several times to make the wall moist. Generally, it will be carried out on the day before the wall plastering, and this step can be said to be a step that must be operated, so as to avoid the excessive absorption of the moisture of the cement mortar by the wall base layer, resulting in shrinkage and hollowing; This amount of watering moisture needs to penetrate the depth of the block 5 10mm is best. When plastering, the wall is still dry and not wet, and water should be sprayed again to make the wall moist to avoid the absorption of water by the base layer of the wall.

3.Hang the net and shake the hair.

At the junction of the wall material of mixed cement and concrete and aerated blocks, it should be treated with a full steel wire mesh to prevent the wall from cracking. The hanging grid is recommended to be steel wire mesh, and the grid spacing is 10 20mm, diameter. The overlap position between the grid and the base layer of each material should not be less than 100mm.

4.Find rules and paste ashes.

According to the flatness and verticality of the wall surface and the thickness that needs to be completed, the thickness of the plastering needs to be determined after on-site measurement, but the thickness of the plastering layer cannot be less than 7mm. After the thickness is determined, paste the ash cake with wire pendants, square rulers, pull through lines and other methods; The ash cake should be made of 1 3 cement mortar into a 30 50mm square shape, and the horizontal distance is about. Around.

5.Do corner protection and punching.

Before large-scale plastering, in order to ensure that the sunny corners of the wall column are upright and square when plastering, it is necessary to protect the corners of the doors and windows, cylinders and other parts with yin and yang angles before plastering. The operation method is shown in the figure; At the same time, the corner line also plays the role of punching, so the mortar used is the same as the punching mortar, and the height should not be greater than 2 meters, and the width of both sides should not be less than 50mm.

Precautions for wall plastering construction.

1. First plaster a thin layer of ash (attachment layer, 2 5mm is appropriate), the thin ash layer requires the mortar to be compacted and fully squeezed into the small gaps;

2. The thickness of the plastering should be 7mm and 9mm for each layered scraping, leveling, and flushing at the height of the punching bar;

3. Comprehensively check whether the bottom ash is smooth, ensure that the yin and yang angles are square, the ash at the pipeline is squeezed, the junction between the wall and the roof is smooth and flat, and check the vertical and flat situation of the wall with the supporting line, and the mortar scattered on the ground should be cleaned up in time after the plastering is completed.

There are two types of plastering:

Internal plastering: internal plastering is mainly to protect the wall and improve indoor sanitary conditions, enhance light reflection and beautify the environment; In rooms that are susceptible to moisture or acid and alkali corrosion, it mainly plays the role of protecting walls, ceilings and floors. In building construction, the decoration project that uses the general plastering structure as the finishing layer is usually called "blank decoration".

Only after this process can the walls be further decorated (painting, wallpapering, diatom mud, etc.).

External plastering: External plastering is mainly to protect walls, ceilings, roofs and other parts from the erosion of wind, rain and snow, improve the ability of the wall to prevent moisture, weathering and heat insulation, enhance the durability of the wall, and is also an effective measure for artistic treatment of various building surfaces.

The role of plastering:

1. The protection function protects the wall from the erosion of wind, rain and snow, increases the ability of the wall to prevent moisture, weathering and heat insulation, and improves the durability and thermal performance of the wall;

2. Beautify the function, improve the indoor sanitary conditions, purify the air, beautify the environment, and improve the comfort of living.

1. Clean the wall.

Before construction, we need to conduct a comprehensive inspection of the wall, carefully see if the wall has cracks, looseness or mortar is not full, etc., if there are these problems, it is recommended that you use cement mortar to fill it densely. For the protruding parts of the wall, we should cut and flatten, and at the same time, we should use the hanging wire board to check the vertical deviation and flatness of the wall, and the plastering base should be treated well.

2. Watering and moistening.

Next, we need to clean the surface of the wall from the floating soil, and then pour it with water several times to moisten it. Watering should be in accordance with the order from top to bottom, so that the wall can be poured through, and the wall watering and wetting can make the plastering layer have good coagulation and hardening conditions. The amount of watering should be 8-10mm deep for water infiltration blocks, and watering should be carried out the day before plastering.

If the wall is still dry and not wet enough when plastering, we should spray water again, but the wall does not show floating water when plastering, which is conducive to the growth of mortar strength and does not appear hollow and cracked.

3. Apply interface agent.

In order to make the cement and plastered wall adhere tightly, we also need to apply a layer of interface agent, the proportion of the interface agent needs to be appropriate, and then let it solidify on the smooth surface of the base layer, so that it can be broken by hand after 48 hours of curing.

4. Hang vertically, plastering cake punching.

In the plastering, we should determine the thickness of the interior wall plastering according to the situation of the wall base, generally speaking, the thickness of the interior wall plastering is about 20mm, and the minimum should not be less than 7mm. When operating, the ash cake should be pasted first, and then the ash cake should be pasted; When pasting the ash cake, the correct position of the ash cake should be selected according to the indoor plastering requirements, and the general ash cake spacing should not be more than 1500mm, and it should be 30mm from the ground. When the ash cake is about to dry, we have to wipe a 100mm wide mortar punch between the ash cake, and then scrape it with a scraper, its thickness should be level with the ash cake, and wait until the punch bar is slightly dry before the bottom plastering.

5. Wipe the bottom layer of mortar.

Generally speaking, the bottom plaster can be plastered after 2 hours of punching, and this time should not be too early or too late. After plastering, we should comprehensively check whether the bottom ash is flat, whether the yin and yang angles are square, whether the junction of the yin corners, and the junction between the wall and the roof are smooth and flat, and check the verticality and smoothness of the wall with a ruler board. In addition, the plastering surface should be smooth, and the ground sand and ash should also be cleaned in time.

6. Plaster the face ash.

When the bottom plaster is divided into seven parts, we can apply the plaster. In this process, it is best to be operated by two people at the same time, one person first scrapes thinly, and the other person immediately smooths it, according to the order of first up and then down, and then rushes to compact, and then presses it again with a steel trowel, and finally calenders with a plastic trowel along the trowel pattern.

If the wall is plastered, it mainly depends on what the hell is your wall wet grinding cement plaster or plastering, if the cement plaster, then the wall will be overtime after more than 70,000 years to buy it back directly.

Hello is happy to answer your questions, your current question is on the steps of plastering the walls. First of all, we went to the market to buy high-quality putty powder, and cellulose. Then go to the construction site according to the ratio of water and putty powder, cellulose, and good putty powder.

Then you can wipe the wall, the first time to wipe a little thicker, find out the flat surface of the wall, and then the second time to continue to wipe, wipe a little less. Then finally wait for the wall to dry, use sand to smooth the wall, and then use a roller to evenly apply the latex paint to the wall, and wait for the wall to dry and draw again. And finally it's done.

Here's a little bit of advice from me personally, I hope it can help you.

Method steps ahead of the child Fu Fu Fu Fu sub-method steps you can. With professional personnel, they don't go, the methods are very fast. Convenient.

4. Find rules and paste ash cakes.

According to the flatness of the wall, the thickness of the plastering layer should not be less than 7mm in determining the thickness of the wall plastering. After the thickness is determined, paste the ash cake with a line pendant, square ruler, and other methods.

5. Do corner protection and punching.

In order to ensure the uprightness of the wall when plastering, it is necessary to protect the corners of the doors and windows and other yin and yang corners before plastering.
