What precautions are required for interior wall plastering?

Working conditions for interior wall plastering: roof waterproofing or upper floor surface layer has been completed, no seepage or leakage. The main structure has been inspected and accepted and met the corresponding requirements, and the doors, windows, floor embedded parts and various pipes have been installed (radiators installed against the wall and dense pipe rooms should be plastered before installation) and inspected qualified.

The ambient temperature of advanced plastering should generally not be lower than +5, and the ambient temperature of intermediate and ordinary plastering should not be lower than 0. Construction method of interior wall plastering: find rules to ensure that the wall plastering is vertical and flat, to achieve the purpose of decoration, you must find rules before plastering.

The way to find the rules of the sign block is to first use the supporting board to comprehensively check the vertical flatness of the surface of the brick wall, and determine the thickness of the wall plastering according to the actual situation of the inspection and taking into account the total average thickness of the plaster. Then, at a height of about 2m, 10 500px from the two shaded corners of the wall, make a standard sign block with the bottom plastering mortar, the thickness is the thickness of the plastering layer, and the size is about 125px square.

Based on these two standard sign blocks, the thickness of the two sign blocks corresponding to the lower part of the wall is determined vertically with the supporting plate and the hanging, and its position is at the upper mouth of the baseboard, so that the upper and lower two sign blocks are on a vertical line. After the standard sign block is done, nail the nail in the brick wall crack near the sign block, tie the small line to hang the horizontal line (note that the small line should be 1mm away from the sign block), and then add a number of sign blocks according to the spacing. All windows and buttresses must be marked blocks.

Standard bars. Standard bar, also called "punching", "out of the column head", is to wipe out a long trapezoidal ash ridge between the upper and lower two sign blocks, its width is about 250px, and the thickness is equal to the sign block, as the standard for plastering the bottom of the wall plastering plaster. The practice is to wipe a layer in the middle of the upper and lower two sign blocks, and then wipe the second time to protrude into a figure-eight shape, which is about 25px more than the ash cake, and then rub it with a wooden bar close to the upper and right sides of the ash cake until the standard bar is rubbed as flat as the mark block, and at the same time, the two sides of the standard bar should be repaired into an inclined plane with a scraper, so that it is connected with the plastering layer.

The mortar used for the standard reinforcement should be the same as the plastering bottom mortar.

The basic requirements for the construction quality and safety of interior wall plastering projects: the variety and quality of materials used in plastering must meet the design requirements and the provisions of the current material standards; The bond between each plastering layer and between the plastering layer and the substrate must be firm, without delamination, hollowing, and no defects such as ash explosion and cracks in the surface layer. Surface:

The surface is smooth, clean, the joints are smooth, and the line angles are straight and clear.

The gap between the corner protection, doors and windows and the wall, the corner protection conforms to the provisions of the construction specification, and the surface is smooth and smooth. The gap between the door and window frame and the wall is filled densely, and the surface is smooth; Plastered surfaces behind holes, slots, boxes and pipes, of correct size, neat and smooth edges, and flat behind pipes; Grid strip (seam): width, depth, uniformity, strip (seam) smooth and smooth, neat corners, horizontal and vertical, smooth.

Construction requirements: wall plastering cement mortar. Grassroots treatment:

First of all, the protruding concrete is flattened, then watered and moistened, and then, with 1:1 cement fine mortar mixed with 107 glue with 20% water weight, spray or use a broom to throw the mortar to the top and wall (concrete wall), until the cement mortar pimple is 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); Straight, set square, find rules, paste ash cake.

Control and elimination measures of common quality problems of plastering engineering In the construction of buildings, some common quality problems often occur, the light ones cause unnecessary trouble to the users, and the heavy ones have hidden quality hazards, which affect the overall quality of the project and cause unnecessary losses to the country and the people. How to control and eliminate common quality problems is one of the most common topics in the construction industry. Plastering engineering is a weak link in building construction, and its main manifestations are:

The construction is still mainly manual operation, with many wet operations and unstable quality. At present, indoor and outdoor plastering are generally cracked, hollow, shelling and cover ash rough, blistering

The yin and yang angles are not perpendicular and square, and the external wall is polluted and other quality problems. The causes and protective measures of these quality problems are introduced as follows: brick wall, concrete base plastering hollow, cracks After the wall plastering, after a period of time, it is often at the junction of the door and window frame and the wall, the intersection of the wood base and the masonry and concrete base, the part of the base level with a large deviation, as well as the wall skirt, the upper mouth of the baseboard, etc.

Cause analysis: the grassroots cleaning is not clean or improperly handled; The wall is watered impermeably, and the moisture in the mortar is quickly absorbed by the base layer (or bottom ash) after plastering, which affects the adhesion.

The decoration of the rough house is a big project, and each process has fixed operation steps, such as interior wall plastering is also a project that needs attention, so what are the precautions for interior wall plastering? Next, let me take you to take a look.

1. Handover acceptance: the selected materials must not be wrong, and it is best to pass the quality inspection, so that you can use it with confidence. Also remember to pop the line out before construction.

2. Grassroots treatment: check whether the doors and windows are firm, if there are gaps, then it should be plugged tightly. The rebar head should not be exposed, it should be cut off.

3. Chiseling and watering: Check the position of each accessory and whether it is installed correctly, especially the distribution box, its junction box must be tightly plugged with paper.

4. Find the right house: Before construction, it is necessary to determine the final plan, and at the same time, it is necessary to do a good job of the model room, so that professionals can check it to see if it is qualified.

5. Make plastering sign blocks: every 150 cm you need to hang a line, and at the same time you need to make a piece of ash cake, waterproof measures are also essential.

6. Set the standard reinforcement: first do the filling, the width is controlled at about 10 cm, and the time for about two hours can be plastered after completion.

7. Plastering: To deal with the details first, such as around the window frame, as well as around the door frame, these places should be wiped first, and after they are done, they can be painted on a large area.

In view of the construction process of building interior wall plastering, at this stage, what are the regulations on building interior wall plastering in China? What's the basics? The following is the relevant content of professional architectural terminology of Zhongda Consulting to sort out the requirements for interior wall plastering, and the basic situation is as follows:

1. The base should be cleaned first, and the concrete base should be sprayed with pure cement slurry in granular form to facilitate bonding; The base layer of the brick wall should be watered and moistened beforehand.

2. The construction process is: hanging line, plastering ash cake, making punching ribs, wiping the first time to hide the bottom ash, wiping the second time to wipe the bottom ash, plastering the surface layer of ash, and calendering with a plastic spatula.

3. The cement mortar mix ratio for priming is: cement 1: sand 3: fly ash: lime paste. The surface layer is mixed with 10 white cement with paper gluten ash.

4. The mortar is mechanically stirred, and the feeding sequence is: first sand, then lime paste, then cement, and finally fly ash. Stir for no less than 120 minutes.

5. The mortar should be stirred evenly, and the consistency of the stucco mortar is generally 7-10cm. The cement mortar should be used up within 3 hours after mixing.

6. Cement with a factory date of more than three months shall not be used. River sand should be sieved and stirred with clean water. Paper ash must not contain lumps (hard lumps).

7. When the bottom ash of the second pass is dry, the cover ash can be painted. If you wait until it is completely dry before applying the covering, you need to water it a day beforehand.

8. Before the ceiling is primed, the horizontal control line should be bounced around it, and the line should be pasted with ash cake and punched ribs, and then the bottom ash should be wiped twice, and the hair should be smoothed with a scraper.

9. The bottom of the beam and the side of the beam should be pasted with ash cake and punched ribs. The bottom of the beam is horizontal and the side of the beam is vertical; The yin and yang angles are square. The multi-span continuous beam should be tightened to make nails.

10. All column corners, wall corners, door and window corners, etc. should be cleared into corner protection: that is, the corners should be painted with pure cement mortar with a higher grade than the priming mortar.

11. The foundation of the same wall should be completed coherently at one time. Avoid uneven joints and inconsistent colors of priming mortar on the same wall.

12. All horizontal planes should be horizontal; All facades should be vertical; All yin and yang angles should be square. It is strictly forbidden to produce cracks on the surface after drying.

13. The crack between the top of the filling wall and the bottom of the beam should be plugged and compacted with micro-expanded cement mortar before formal priming to prevent cracks in the future.

14. The floor ash (mortar falling when building a brick wall) around the floor before painting should be cleaned up first and transported to the designated place on the ground for stacking.

15. The stucco scaffold shall not touch the wall, and attention should be paid to protecting the finished product when dismantling the scaffold, so as to avoid the loss of life and property caused by secondary repair.

16. Each skilled worker should take half an hour to check the results of the day's work when he gets off work every day, and repair the quality problems in time.

Interior wall plastering is the first link in the construction of masonry, interior wall plastering is mainly to ensure that the plastering is firmly bonded, to avoid the plastering layer shelling, cracking, to ensure the quality of plastering, and the interior wall plastering is prone to quality problems. So, let's introduce the steps of interior wall plastering and what are the common problems of interior wall plastering.

Steps for plastering interior walls.

1. Grassroots cleanup.

Thoroughly clean the base layer and repair the uneven places on the wall to keep the wall clean and tidy.

2. The wall is wet.

To allow the base layer of the wall to absorb water, it should first be carried out the day before the wall plastering, and after the wall is cleaned and treated, the wall should be watered to make the wall moist.

3. Hang the net and shake the hair.

In order to prevent the wall from cracking, it can be treated with steel wire mesh on the concrete and aerated block type of wall.

4. Find rules and paste ash cakes.

After the thickness of the wall plastering is decided, paste the ash cake with wire pendants, square rulers, pull through lines and other methods.

5. Do corner protection and punching.

Before plastering the wall, the yin and yang corners such as doors and windows, and columns should be treated with corner protection.

What are the common problems of 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 in a certain range, keep about 20mm, the operation should be layered, intermittent plastering, the first time the ash can be wiped after the second time, 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.

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.

At this stage, what are the regulations of construction enterprises on interior wall plastering technology? What's the basics? The following is the relevant content of Zhongda Consulting to sort out the technical requirements for interior wall plastering, professional architectural terminology, and the basic situation is as follows:

The day before plastering the bottom of the plaster, the wall should be watered and moistened, and the inner moisture should be dried, and the base should be laid with 1:3 cement mortar, and the surface layer should be 1:1:

4. Cooperate with plastering and calendering. When the wall in the kitchen, bathroom and laundry room is roughened, the root is 300 compacted from the ground, and the surface layer is wiped with 1:3 cement mortar.

The roots of other interior walls are 200 meters off the ground, and the sponge is used to pull fine hair to make baseboards, and the wall is watered and maintained for 3-5 days.

Technical requirements for interior wall plastering.

1. When making ash cake on the wall before plastering, it is necessary to hang the line and pay attention to the axis of the opening, strictly control the thickness of the wall panel, and the axis of the opening must be uniform, and the ash cake must be vertical, smooth, smooth and consistent, and the spacing of the ash cake should not be too large.

2. The connection between the door and window frame and the wall is tightly filled with 1: cement mortar. The corners of the door and window openings are 1:

Cement mortar wiping corners according to the thickness of the ash cake to wipe, must be plastered twice, the construction must pay attention to vertical, smooth and smooth, neat edges and corners, consistent color, no cracks and hollowing.

3. Interior wall plastering must pay attention to the wire box, behind the bathroom pipe, air conditioning port, exhaust hole, and behind the pipe, it must be plastered before installation, so that the pipeline can be installed, and the surface is smooth and smooth.

4, the wall plastering in strict accordance with the mortar mix ratio measurement and stirring, before plastering, on the concrete surface must be treated with interface binder, and maintenance can be carried out in a large area of plastering, wall plastering using 1:1:6 mortar is scraped twice to live, the surface must be smooth and flat, no seams, no cracks and hollow drum phenomenon, uniform color, yin and yang corners to square and clear, there are lines or drainage parts must be done to drip the hungry waterline, the inner height and outsole, the depth of the drip line shall not be less than 10, the lines should be smooth and consistent.

5. For aerated concrete blocks before whitewashing, spray wool with 107 glue and pure cement, and timely maintenance should be carried out after spraying, and a large area of whitewash should be carried out after all wetting before whitewashing.

6. The ceiling is plastered with 1:1:4 mortar. When plastering, the surface should be smooth and smooth, no cracks, the color should be consistent and uniform, and there should be no hollowing phenomenon.

7. The whitewash area must control the thickness of the whitewash, not too large, and the ultra-thick part of the plastering shall not exceed 10 each time. If it is found that there are hollows, falling off, and cracking, all of them must be reworked and repaired, and then the construction continues.

8. The plastering is full of deviations, the verticality is 3, the flatness is 2, and the yin and yang angles are square, and the silver positive angle is vertically 2, which must be renovated if the above requirements are exceeded.
