What does interior wall plastering include, the difference between interior plastering interior plas

Wall plastering refers to the surface layer of cement mortar, mixed mortar and white mortar plastered on the wall. The interior wall plastering process is as follows:

1.The following preparations should be made before the large stucco (main body acceptance):

1) Make ash cake: According to the surface of the base level, vertical situation, hang the vertical line, pull the wall surface of the long line, must be square yin and yang corners, after inspection to determine the thickness of the plaster, but the thinnest point should not be less than 7mm, the thickest part is not more than 20mm. Ash cake should be used 1:

3. The cement mortar is made into a 3cm square shape. When making ash cakes, make a ash cake at 30cm under the flat roof and on the floor along the height range, and make another ash cake in the middle;

2) Corner protection: The sunny corners of walls, columns and door openings should be leveled with 1:2 cement mortar and ash cake, and then wiped into small corners after the mortar is slightly dry.

The width of each side should not be greater than 5cm. All corners must be square and straight. The size of the door opening is uniform, and each side is reduced by 15mm.

3) The oil stain and paint on the surface of the concrete should be brushed with a wire brush before plastering, and the surface of the concrete should be brushed with an interface agent, and the screw hole on the external wall must be embedded with cement mortar.

2.Before painting, the brick wall should be watered thoroughly overnight, and the wall should be watered and moistened from top to bottom with a thin pipe.

3.The cast-in-place board is cut straight 20cm upwards when painting, and the baseboard is darkened with 1:3 cement mortar powder after the floor is ready.

4.Plastering bottom ash: the thickness of the bottom ash is lower than the ash cake 6 8mm, first plastered with a thin layer to make it solid with the wall, then layered plastering, and then with a large scraper ruler in the horizontal direction from top to bottom slowly scraped, and finally with a broom to sweep the hair.

5.Plastering surface layer mortar: The surface layer mortar is painted flat with the ash cake, and the sand rate should not be too coarse.

The bottom ash must be painted overnight, the next day the surface layer of mortar, scraped straight with a scraper and then flattened with a wooden crab, and then calendered horizontally with an iron plaster, and the yin corner is pumped with an angle iron. The texture of the iron trowel should be straightened out left and right, and there should be no messy iron plate lines, so that the entire wall surface is smooth and smooth, and the fine lines are consistent. Then, the wall is tracked and inspected with a detection ruler, mainly to check the flatness, verticality, squareness and straightness of the wall and the square and straight angles of yin and yang, and whether there is a deviation at the intersection of the beam and the column.

If there is any deviation, it should be repaired in time until it is qualified.

Does the so-called interior wall plastering include ceiling and floor plastering? Yes.

1. The plastering position is different.

The position of plastering is different, among which exterior wall plastering is outdoor plastering; Interior wall plastering is indoor plastering; Interior plastering is interior wall plastering.

2. The purpose is different.

The purpose of plastering is different, in which interior plastering and interior wall plastering are to protect the wall; The façade is plastered for decoration.

1 Exterior wall plastering is outdoor 2 Interior wall plastering is indoor (adding: more really, it is indoor plastering inside the window opening, otherwise it belongs to outdoor plastering) 3 Indoor plastering is interior plastering (you can refer to the previous two answers) Got it?

Indoor plastering refers to indoor filling walls, shear wall plastering, including door and window openings, and exterior wall plastering, including outdoor parts, air conditioning panels, filling walls, etc.

In order to protect the smoothness of the gray surface and avoid cracks, the plastering layer should generally be composed of layers and operated in layers. Scientific plastering work can play a role in moisture-proof, weather-proof, heat insulation and other functions.

The plastering layer is generally composed of three layers: bottom ash, middle ash and surface ash.

Different parts of the plastering base require different plastering thicknesses.

Ordinary plastering - 18mm; The surface is smooth and clean, and the stubble is smooth.

Intermediate plastering - 20mm; The surface is smooth, clean, the stubble is smooth, and the line angle is straight and clear.

High-grade plastering — 25 mm. The surface is smooth, clean, uniform in color, no wipe, and the line corners and gray lines are straight and square, clear and beautiful.

When decorating, it will involve the process of interior wall plastering, many people are estimated to not be able to clear this professional term, and they may not be able to name this step, so let's introduce to you what interior wall plastering means, and what are the problems that are prone to occur in interior wall plastering.

1. What does interior wall plastering mean.

Interior wall plastering refers to the surface layer of stucco that is smoothed with a trowel. A process is applied to the concrete floor or the roof where the tiles are installed, i.e. the plaster coating. To put it simply, wall plastering is actually to coat the wall with cement mortar or mixed mortar and so on.

Wall plastering is an essential process when building a house, so that the wall can last longer.

Second, what are the problems that are prone to occur in interior wall plastering.

1. Poor bonding, hollowing, cracks.

When plastering interior walls, it is sometimes found that the bond between the stucco layer and the substrate is not firm, resulting in hollowing, cracks and other problems, which is mainly because the base is not clean, not wet enough, and in the process of mortar strength growth and hardening, uneven shrinkage stress is generated, so the phenomenon of dry shrinkage cracks is formed.

2. The plastering layer is too thick.

The plastering layer will be too thick during the construction, at this time the plastering layer can be cracked, and the thickness of the plastering layer can be controlled within a certain range, keeping about 20mm scattered and rising, the operation should be layered, intermittent plastering, and the ash can only be wiped twice after solidifying and washing, and it must not be completed once digitally.

3. The side seams of the door and window frames are not stuffed with ash or the ash is not solid.

When plastering the interior wall, it is easy to have problems such as hollowing and cracks on both sides of the window frame, so in order to avoid this situation, the door and window cracks should be responsible for a special person.

The above is what does interior wall plastering mean, what are the problems that are prone to interior wall plastering, I hope it can help you understand the relevant knowledge of interior wall plastering, more decoration knowledge, decoration company evaluation, decoration cases, please continue to pay attention.

Interior wall plastering refers to the plastering of cement mortar, mixed mortar, and white plaster surface layer engineering on the wall.

1. Wall plastering cement mortar.

a. Base treatment: first of all, the protruding concrete is flattened, and then watered and moistened, and then, with 1:1 cement fine mortar mixed with 20% of the weight of 107 glue, spray or use a broom to throw the mortar to the top and wall (concrete wall), until the cement mortar pimples are all glued to the smooth surface of the concrete.

Before this process, the concrete and the brick wall connection are nailed with steel wire mesh (width 300);

B. Straight, set square, find rules, paste ash cake: according to the smoothness and verticality of the surface of the base layer, the thickness of the plastering layer is determined after inspection, and the ash cake is suitable for use.

1:3 cement mortar, made 50m square, the water ridge is changed to left and right;

c. Gluten: According to the same 1:3 cement mortar as the plastering layer, the number of tendons should be determined according to the height of the layer;

D. Corner protection: According to the ash cake and punching bar, the corners of the doors and windows and the walls and the sunny corners of the cylindrical surface should be plastered with cement corners, and the high cherry blossom shed degree should not be less than 2m, and the width of each side should not be less than 50mm (1:2 cement mortar).

E, plastering bottom plaster: generally should be the day before plastering the wall with water poured through, first brush 107 colloidal cement, with the brush with the primer, the bottom ash using 1:3 cement mortar. It should be layered and smoothed with the punched ribs, scraped and straightened with a large bar, and the wooden trowel was flattened;

F. Plastering cement mortar cover ash: the next day after the bottom mortar is wiped, the wall surface is wetted first, and the cover work can be carried out, using 1:2 cement dura fiber mortar cover (dura fiber M3 cement mortar), and scraping and straightening with a large bar.

2. Concrete ceiling plastered with cement mortar.

a. Base treatment: (with concrete roof plastered with cement mortar).

B. elastic line, set square, find rules: according to the +50cm horizontal line to find out the horizontal line close to the roof around the roof as the roof plastering horizontal buried reed control line;

c. Brush plain cement slurry and plaster: first brush plain cement slurry, then use 1:2 cement mortar to base and pull hair, and then use 1:1 cement mortar to wipe the surface, which should be horizontal and vertical evenly smooth.

Precautions for interior wall plastering construction:

Before plastering the interior wall, it is necessary to make a detailed disclosure to the operator, especially the control of the detailed quality points;

Hold as a model room; Unqualified teams are resolutely not used;

In the process of work, managers should often check the quality points that should be paid attention to, and solve problems immediately.

Interior wall plastering is the initial link in the construction of home decoration masonry, the main purpose of interior wall plastering is to ensure that the plastering is firmly balanced, to prevent the plastering layer from shelling, cracking, and to ensure the quality of plastering. Interior wall plastering is prone to quality problems, so what are the common problems of interior wall plastering and how to do wall plastering? Let's find out!

What are the common problems of interior wall plastering.

1. Poor bonding, hollowing, cracks.

When plastering interior walls, the bond between the stucco layer and the substrate is often not firm, resulting in hollowing and cracks. It is mainly because the base is not cleaned and not wet enough, and the mortar will produce uneven shrinkage stress in the process of strength growth and hardening, so the phenomenon of dry shrinkage cracks is formed.

2. The plastering layer is too thick.

The plastering layer often appears too thick during the construction of the current cave mountain, especially if it is a success, the plastering layer will be cracked. The thickness of the plastering layer should be controlled within a certain range, and it is usually better to keep it at about 20mm. The operation should be layered and intermittently plastered, and the second time can only be wiped after the first time the ash is solidified, and it must not be completed at one time.

3. The side seams of the door and window frames are not stuffed with ash or the ash is not solid.

During the construction of wall plastering, it is often easy to produce hollows and cracks on both sides of the window frame, so in order to avoid this situation, the door and window joints should be responsible for a special person.

How to do wall plastering.

1.Grassroots cleanup.

Before plastering the wall, it is necessary to clean the base layer of the wall so that the wall is free of pollutants such as floating dust and granular debris. If there are missing corners on the wall, these areas should be repaired.

2.The walls are moist.

After that, it is also necessary to keep the wall moist by pouring water on the wall the day before plastering. This step is mainly to avoid excessive absorption of moisture by the wall base layer of cement mortar, resulting in the problem of shrinkage and hollowing.

3.Hang the net and shake the hair.

If the wall construction is mixed with cement and concrete, it should be treated with steel wire mesh to prevent the wall from cracking. And the grid spacing is best 10 20mm, diameter, and 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, the thickness of the wall plastering is determined, but the minimum thickness of the plastering layer cannot be less than 7mm. After the thickness is determined, then use the line pendant, square ruler and other methods to paste the ash cake, the ash cake should be made into a 30 50mm square shape, and the horizontal distance is about about that.

5.Do corner protection and punching.

If it is a large-area wall plastering, in order to ensure the squareness of the wall column surface when the sunny corner is plastered, it is necessary to protect the corners of the doors, windows, cylinders and other parts before plastering.
