How to do putty powder leveling, putty powder leveling construction process introduction?

There are two types of putty: interior wall and exterior wall:

The theoretical consumption value of the amount of putty used for exterior walls is kilograms of square meters. Add water and stir well, leave for 10 minutes, and then stir before use. The surface of the wall is smooth or new building materials, such as gypsum partition board and paper gypsum board, etc., which need to be treated with interface agents.

Due to the high strength of the putty, the putty should be leveled with a scraper when the putty is in a semi-dry state.

The theoretical consumption value of the amount of putty used in the interior wall is kilogram square meters. Add water and stir well, leave for 10 minutes, and then stir before use. The surface of the wall should be solid and free of floating ash and dirt, and the moisture content of the wall surface should be less than 5%.

Putty leveling should be completed in a semi-dry state, and it can be leveled with an abrasive cloth after curing.

Process flow: base treatment, repair putty, scrape putty, apply emulsion thin paint once, apply waterproof latex paint for exterior wall twice. Grassroots treatment:

First of all, the peeling, loosening and bulging on the base layer such as the wall are removed and chiseled, and the dust, dirt, splash and mortar flow marks and other debris remaining on the surface of the base layer are removed and swept away. Repair putty: Use exterior wall mortar and flexible greasy to level the pits, gaps and other bumps on the wall and other base layers, and use sandpaper to smooth the protrusions after drying, and sweep away the floating dust.

Scraping putty: The number of passes of scraping putty can be determined by the flatness of the base layer or wall. Apply a thin emulsion coating:

The application sequence should be applied to the wall first, and then down. Clean the wall first. Emulsion thin paints are generally applied with a roller.

The emulsion thin paint should be stirred evenly before use, and diluted with water appropriately to prevent the first coat from being applied to prevent the first coating.

Step 1: Apply putty powder first.

Step 2: Wait for the putty powder to dry (one to two days) before grinding.

Step 3: Apply latex paint after sanding.

How thick can leveling putty be found? On what basis? The purpose of wall scraping putty is to make the wall surface smooth.

Putty has a certain thickness, but not too thick. Too thick is not good, too thin will not achieve the expected decorative effect. The person in charge of the construction said that if the flatness of the wall exceeds 5mm, the putty can be scraped at one time, and the thickness that can be leveled shall prevail.

It is recommended to scrape no more than 2cm in a single batch, otherwise cracks and other problems may occur. If the leveling thickness exceeds 2 cm, it is recommended to do so by scraping in multiple batches.

When the flatness of the wall is less than 5mm, fine leveling materials can be used for leveling. Fine leveling materials can generally be scraped 2 or 3 times, and should be as uniform as possible. In order to obtain better performance results during painting, the fine leveling material is generally scraped and polished once with fine sandpaper to make the wall surface more flat and smooth.

After that, there is no need to polish the walls if you do not plan to paint them. It should also be noted that waterproof putty becomes very hard after a week of full reinforcement, at which point it is difficult to sand. Therefore, it is advisable to sanding putty within 1 to 2 days after applying the last layer of material to the wall.

When sanding, a light bulb of more than 200 watts should be used for wall lighting, and the flatness should be checked when sanding to get a better effect.

When decorating the wall, pay attention to leveling. For leveling, putty powder can be used for leveling. Then, let's introduce the filling thickness of scraping putty powder.

1. How thick can the leveling putty powder be filled?

Leveling putty powder can be supplemented. If the screed layer is too thick, it should be scraped in layers to reduce the thickness of a scraping level, reduce the drying and shrinkage strength of curing, and avoid putty cracking. In addition, when scraping putty, the inclination angle should be controlled and the force should be evenly used to ensure that the putty is full.

2. Precautions for scraping putty.

1. When scraping putty, pay attention to leveling to keep the wall flat and without concave and convex.

2. When scraping putty on the wall, try to scrape it three times. After each scraping of putty, the second putty must be completely dry before it can be used. In this way, the putty can be applied firmly without cracking.

3. When scraping putty, avoid blowing cold air directly into it. While the wall looks like it can be dried, it actually locks in the water on the wall. If the next operation is carried out at this time, the dry wall material will evaporate and cause cracking when heated in winter.

4. Due to the strong adsorption of the base layer, the primer can be used to seal the putty when scraping to prevent the putty adhesive from being adsorbed by the base layer and affecting the adhesion of the putty.

5. Pay attention to the quality when scraping putty. Paint the roof first, then the walls. The tilt of the scraper must be well controlled, and the force must be uniform to ensure that the putty is full.

Leveling putty powder can be repaired. If the leveling is too thick, it should be scraped in layers, which can reduce the thickness of a batch scraping, reduce the curing dry shrinkage strength, and avoid the cracking of putty.

This should be determined according to the actual situation, in general, it should not be too thick, and it should be determined according to the specific pothole, if it is particularly large, it is necessary to use cement to level it first.

Generally, the thickness of the tweezers of a single layer is between 1mnn, and if the putty is scraped to the second layer normally, the thickness should be controlled at about 3 5mn.

What kind of putty powder should be used for wall leveling? Let's tell you about the Meien putty powder.

1. Caulking plaster.

Meien caulking gypsum is mainly based on fine gypsum powder, which is used for caulking and leveling joints and nail holes between gypsum boards, and is also suitable for repairing indoor wall holes, gaps, trunking and local flatness of places with poor flatness.

Changsha Hengkang Building Materials **** from wall environmental protection putty powder to natural nano dry powder paint, active dry powder mirror art paint (silk screen), active dry powder texture art paint full matching.

Features: early strength, fast hardening, fire prevention, heat preservation, sound insulation and automatic adjustment of indoor temperature, at the same time, it has good workability of construction, high bonding strength, not easy to hollow, no cracking, and can be quickly constructed.

Caulking gypsum is mainly made of fine gypsum powder, the aggregate is very delicate, the hardness is not strong, the flexibility is not good, and the water resistance is relatively poor, so the large-area leveling is easy to peel off and crack. Therefore, it is only suitable for gypsum board joints, yin and yang corner leveling repair, wire slotting or partial repair.

2. Plaster.

Stucco gypsum is a newer, more environmentally friendly, more economical national key promotion of cement mortar, not only the strength of cement, but also more healthy and environmentally friendly than cement, durable, adhesion, not easy to chalver, no cracking, no hollowing, no powder and other advantages, easy to use, cost-saving, currently more and more widely used in building interior wall plastering.

Disadvantages of stucco gypsum: generally the wall of the new house is concrete pouring, the wall flatness error is large, and the plaster is directly scraped and painted with a one-time thickness leveling, although the error of the wall is qualified, but such a wall will definitely delaminate and crack after a period of time, and the wall skin will even fall off. Therefore, stucco plaster is not ideal.

It is best to use exterior wall ash for wall leveling, and the hardness after scraping is much better than putty powder, and the moisture-proof ability is better than putty powder.

It is best to use plaster for wall leveling, and it is best to use plaster at the bottom of the plaster, that is, to paint plaster, and the thickness needs to be about 2 cm.

Most of them are coated with gypsum powder on the uneven place of the wall, and then apply putty on it, because the gypsum powder putty is relatively hard, so the adhesion is very good, so the plaster powder putty is leveled first, which can reduce the thickness of the ordinary putty, which also increases the firmness of the putty layer.

If the flatness of the wall is too poor, it should be leveled with stucco plaster first, and then scrape the putty for the first time, and then scrape the second time after drying, and polish and spray latex paint with sandpaper when dry.

Summary. What to do if the putty wall is dirty 1. For small pieces of dirt, you can use a clean rag, dipped in water, wring it out and wipe it vigorously until the dirt is cleaned up. 2. For mortar impurities, you can use sandpaper to polish it, coat it with talcum powder, and then polish it again after it is dry.

3. For large areas of stains, it can only be removed first, and then used plaster as a primer, preferably with latex paint. Putty wall leveling construction method 1, clean the wall to clean up the stains on the wall, pay attention to if the wall water absorption is relatively strong, you can use water to moisten or spray glue, back cover treatment. 2. The first time to scrape putty can be scraped with a steel scraper according to the conventional method, the number of scraping can not be too much, generally it is scraped twice, if you encounter the wall of alkali return, you can use the alkali water to seal, and after the alkali water is dried, then use the alkali putty powder as the first layer of bottom material.

3. After the second putty is dry, you can scrape the putty for the second time. When scraping the putty for the second time, the mixture is not easy to be too thin, and the water content is not too large, so as to ensure that the moisture is absorbed by the first putty as soon as possible after the second putty is scraped, and the water content on the wall can be calendered only after the moisture is reduced to a certain extent.

Hello, how to level the wall after scraping the putty powder.

What to do if the putty wall is dirty1, for small pieces of dirt, you can use a clean rag, dipped in water, wring it out and wipe it vigorously until the dirt is cleaned up. 2. For mortar impurities, you can use sandpaper to polish it, apply talcum powder, and then polish it once after it is dry. 3. For large areas of stains, you can only shovel and remove the rent first, and then use gypsum as a base, preferably with latex paint.

Putty wall leveling construction method 1, clean the wall to clean up the stains on the wall, pay attention to if the wall water absorption is relatively strong, you can use water to moisten or spray glue, back cover treatment. 2. The first time to scrape putty can be scraped with a steel scraper according to the conventional method, the number of scraping can not be too much, generally it is scraped twice, if you encounter the wall of alkali return, you can use the alkali water to seal, and after the alkali water is dried, then use the alkali putty powder as the first layer of bottom material. 3. After the second putty is dry, you can scrape the putty for the second time.

When scraping the putty for the second time, the mixture is not easy to be too thin, and the water content is not too large, so as to ensure that the moisture is absorbed by the first putty as soon as possible after the second putty is scraped, and the water content on the wall can be calendered only after the moisture is reduced to a certain extent.

4. Polishing and other early putty for 2-3 days, polish the wall with sandpaper, and then brush the milky white rubber twice after the first polishing, after brushing the milky white glue, the room can not be ventilated, let the milky white rubber dry naturally, and it can not be forced to dry into the Lu dress, and the forced air drying will cause small cracks on the surface of the wall.

For renovation workers, it is good to pay close attention to the decoration of the wall when decorating the interior of the house. For example, before decorating a wall, a base layer is needed and, in the process, leveling. So, the skills of putty leveling for wall base constructionWhat are they?

, the skills of putty leveling for wall base construction: Preparation of leveling materials.

Powder putty: Powder putty is powdered, and it is a surface filling material that must be pre-treated before building a wall. In the conventional process of using sodium carboxymethylcellulose, but soaking in water for a long time after use, the powder is easily soluble in water putty, mixed with water, as long as the application can be used, very convenient.

, the skills of putty leveling for wall base construction: Construction steps.

Clean the walls: Clean the walls and lead cracks and clean them with cement mortar to remove the remaining ash and then clean the walls. We should pay attention to: if the wall is more absorbent, first seal the bottom with wet water or spray glue.

For the first time, putty putty: cement lining of the wall, we better prepare the base material, which not only reduces the cost of construction, but also improves the quality of construction. Preparation method of substrate:

High-quality black cement and indoor frankincense powder can be mixed evenly in a certain proportion. Usually, steel scrapers or scrapers are used to scrape in batches according to the conventional method, and the number of scrapes is not too much, and it is usually applied twice.

Rectification: After leveling the wall, it must be polished. As a rule, after 2-3 days after brushing the second layer of putty powder, the walls or ceiling can be polished with sandpaper.

After the first polishing, you need to brush the white glue twice. If the white glue is brushed, the room cannot be ventilated, so the white glue can be dried naturally in the air and cannot be forced to air dry. Drying with forced air will create small cracks in the surface of the wall.

In fact, ground leveling is not a difficult task. If you want to understand these clearly before leveling, you also need to make the steps and construction precautions clear, so that it is more convenient to work.

Wall leveling is necessary to do when decorating the house, if we do not do wall leveling, then it will not be possible to carry out the next operation, so the wall leveling must be done when decorating the house, the steps of gypsum leveling and putty leveling are what we need to understand in advance, and we will analyze it for youPlaster leveling and putty levelingWhat are the steps and materials?

1. Gypsum leveling and putty leveling steps.

1. Clean the wall.

Clean the peeling and cracks on the wall, and repair it with cement mortar, remove the residual ash and clean it, and then clean the wall. What we need to pay attention to is: if the wall is more absorbent, it should be moistened with water or sprayed with glue to do the back cover.

2. Scrape putty for the first time.

We had better prepare the base material for the cement plastered wall, which can not only reduce the cost of the project, but also improve the quality of the construction. Preparation method of base material: mix evenly with high black cement and indoor putty powder in a certain proportion.

3. Grinding. After the wall is leveled, the polishing work should be carried out. Generally, 2-3 days after brushing the second putty powder, you can use sandpaper to polish the wall or ceiling, and after the first polishing is completed, you need to brush the milky white glue twice.

If the milky rubber is brushed, then the room can not be ventilated, let the milky rubber air dry naturally, and it cannot be forced to air dry, which will cause small cracks on the surface of the wall.

Second, the material of plaster and putty.

1. Gypsum-based full-batch powder is a full-batch material mixed with fine semi-hydrated gypsum powder (cooked gypsum) and a variety of additives. It has the characteristics of high bonding strength, small shortening and deformation, preventing peeling, powder loss and cracking, good suitability, excellent construction function, and green environmental protection. It is suitable for full batch processing of various wall surfaces.

It is a new wall treatment material in the 21st century.

2. Coarse leveling is an indoor wall leveling material mixed with fine semi-hydrated gypsum powder (cooked gypsum), orthopedic materials and a variety of additives. It has the characteristics of high bonding strength, shrinkage and anti-cracking, good suitability, excellent construction function, and green environmental protection. It is suitable for all kinds of bottom leveling treatment, adding slotting, adding holes, and large anterior vacancies.

3. The interior wall leveling and repair mortar is made of flexible and relooseable rubber powder, inorganic gel materials, a variety of natural mineral deposits and various additives, which has excellent bonding strength and crack resistance, and has excellent adhesion to various substrates, which can effectively prevent the poor adhesion, cracking and hollowing appearance of 1 caulking gypsum and stucco gypsum priming.

Decorating a house is a very troublesome thing, so we have to do a good job of every step when decorating the house, so what are the steps and materials of gypsum leveling and putty leveling, and we have also understood it through the introduction.
