Interior wall decoration, how to scrape putty cream?

Generally, the wall can be scraped with putty 2 times, the wall with poor flatness needs to be scraped several times, and the more serious ones need to be leveled by gypsum first, and each putty batch scraping needs to be more than 2 hours.

Wall inspection for decoration wall treatment.

Before decorating the wall, the most important thing is to check the wall to see if it is solid and flat. If there are cracks or holes in the wall, they need to be repaired and leveled with plaster.

Preparation of materials for decoration wall treatment.

Protect the materials and furniture in the room and clean up the floating dust in the room. Then roll the concrete interface paint evenly on one side, and after it dries, you can start scraping the putty. If it is a newly built wall, you need to wait for the 28-day cement curing period before scraping putty.

Scraping putty for decoration wall treatment.

Generally, the wall can be scraped with putty 2 times, the wall with poor flatness needs to be scraped several times, and the more serious ones need to be leveled by gypsum first, and each putty batch scraping needs to be more than 2 hours.

Putty polishing for decoration wall treatment.

After the putty is scraped, it can be sanded, which can be done at night, with a bulb of more than 200 watts close to the wall, and check the flatness while sanding. Grinding is prone to generate a lot of dust, so you need to be prepared to wear a mask.

Brush primer for decoration wall treatment.

Sweep the dust left by the putty on the wall, apply the primer evenly, and wait for the primer to dry.

Brush paint for decoration wall treatment.

In general, the topcoat usually needs to be brushed twice, and it only takes 2-4 hours to wait for the first coat to dry. The second pass will take 1-2 days.

1) Concrete base treatment and leveling. a, the concrete surface flatness of the ruler difference is not more than 6mm, the verticality is not more than 10mm, the line angle, the quality of the surface layer is better, there is no small concrete strips, or a small number of strips, after treatment can still be used, use a chisel to remove the rough particles and small strips on the surface of the concrete, the small strips at the yin angle position must be treated flat, and then use gypsum local leveling to ensure that the flatness and verticality of the wall are within the range of 3mm, and the single batch scraping of gypsum should not be greater than 5mm. The moisture content of the base layer should not be greater than 10% when scraping.

b. When the deviation of the flatness of the wall is 10-30mm, the plaster should be partially leveled to ensure that the flatness and verticality of the wall are within the range of 3mm, and the thickness of the plaster should be within the range of 5-8mm. c. When the wall deviation is greater than 30mm, a special way is required for leveling, such as sealing the wall with gypsum board for leveling. 2) Concrete and gypsum board wall putty, find yin and yang corners.

a. Mix the finished putty powder and stir well. b. Batch scraping putty (scraping with a batch knife, requiring full scraping, no leakage scraping, scraping flat the sand holes, bubbles and uneven places, and the thickness of a single batch scraping should not exceed 1mm.) Generally, three times putty survives.

The first time should be scraped flat in the uneven place, and the second batch should be used after drying, and the large surface should be leveled with a full batch; The third time requires a full batch of putty, a flat batch of light, and pay attention to the corner of the wall, the top corner, the fire sprinkler, the maintenance port and other details of the fine treatment). c. The position of the yin and yang angles requires the elastic line to be straightened and leveled, and each corner should be scraped on one side first, and the other side should be scraped after drying, so as to avoid the yin and yang angles not falling and driving the putty when scraping at the same time. 3) Grinding a. After the putty is dry, touch the wall putty with your hands and the putty has dried, and you can't press it by hand.

After that, the sandpaper is beaten to make the surface smooth and smooth. Generally, 600 sandpaper is used, and sandpaper of different strengths can be selected according to the different strength of putty, but obvious grinding marks should be avoided. b. The yin and yang corners are sandpaper wrapped in sandpaper and polished, and the polishing is required to be straight.

c. The corners of the top surface, the junction of the top surface of the wall and other detailed positions must be polished carefully to ensure that the surface of the putty is smooth and smooth.

It is best to shovel off the original layer, re-hang the putty, and apply latex paint.

: Putty powder for interior walls cannot achieve the decorative effect of exterior wall paints.

Interior wall putty powder will be affected by the outdoor environment and the powder will fall off. For example, one of the most common situations is that under the action of wind and sun exposure, the exterior wall made of interior wall putty powder slowly appears to fall downward.

That is to say, the putty powder on the wall will slowly fall off, and it will become more and more serious with the increase of use time.

Under the rain, the putty powder of the interior wall scraped on the exterior wall quickly fell off. It is also said that the exterior wall scraped by the interior wall putty powder scraped by us, as long as it encounters rainy weather, these putties will slowly drain down with the rainwater, and eventually the putty scraped by the entire exterior wall will fall off, revealing the base layer inside.

The exterior wall must be scraped with special putty for the exterior wall. Before we scrape the putty, the base layer of the exterior wall is treated to be qualified, like a hole, and it must be sealed in place. It is recommended that you use waterproof mortar to apply it once and then scrape the water-resistant putty for the exterior wall.

The coating of the exterior wall should be strictly applied in accordance with the requirements. For example, when we spray real stone paint on the exterior wall, we generally need to spray an alkali-resistant sealing primer first. After that, the base coat of the real stone paint is applied, followed by the top coating, and finally the exterior paint is completed.

Summary. Talcum powder is the base material of putty, which is generally used as putty for wall treatment or wood painting, plus diluted white latex, batch wall, or batch ash wood. Talcum powder is a raw material for putty, a paint used on walls.

What materials are needed for interior wall scraping putty.

Hello, dear, I'm glad you have a problem with the wall scraping putty, we can buy putty powder directly.

If possible, you can add a crack-resistant mesh cloth where there are cracks in the wall.

After scraping the putty, polish it, and then apply latex paint.

I hope mine is helpful to you, if you have any questions, please feel free to ask, thank you If you can, please also trouble your rich little hand to give me a thumbs up Your like is the greatest recognition of me, thank you very much I also hope that you will click on my avatar, pay attention to me if you have relevant questions, and communicate at any time.

Can gypsum powder, talcum powder work?

In general, as long as putty powder is used, putty powder contains a certain amount of talcum powder.

Talcum powder is the base material of putty, which is generally used as putty for wall treatment or wood painting, plus diluted white latex, batch wall, or batch ash wood. Talcum powder is a raw material for putty, a paint used on walls.

1. Requirements and treatment of the base layer: The surface of the base layer is required to be dry, firm and flat, if the flatness is too poor, it can be leveled with plaster. Dust, mud, oil, and release agent on the surface of the new wall should be cleaned.

The surface of the old wall is loose, the shell is raised, and the pulverized part should be completely eradicated. The serious mold part should be solved and the mold part should be cleaned with bleaching powder. If the base layer is closed with primer, the putty can only be scraped after the primer is completely dry.

2. Putty powder preparation: stir evenly according to the ratio of powder: water = 1: or add water or powder according to the actual degree of thinness, until it becomes a uniform and particle-free paste, and use it after 10 minutes.

3. Repair the base layer: Use stucco plaster to level the pits, gaps and other places on the wall and other base layers, and use No. 1 sandpaper to smooth the protrusion after drying, and clean up the floating and sinking. The thickness of plaster should not exceed 10 mm each time, and the plaster should be divided into parts.

4. Grassroots cleaning treatment: ensure that the plastering layer is dry and firm, the hollow drum part has been repaired, and remove the dust, dirt, splash foam and mortar flow marks and other debris remaining on the plastering layer.

5. Scrape the yin and yang angles: When scraping putty, the yin and yang angles are required to be clear and straight. The yang angle is repeatedly extruded by the aluminum alloy rod against the rod; The yin corner is operated with a special tool to make it clear and straight.

7. Precautions: The scraped finished wall must be painted with latex paint within one month, otherwise there will be depowdering and pulverization. If the construction period is too long, it is necessary to apply the back cover primer or interface agent back cover treatment within one month.

1.Preparation.

First of all, the wall should be sanded and cleaned to ensure that the surface is smooth, clean and dust-free.

2.Prepare putty.

Wall putty is divided into pearlescent putty and polished putty, which is determined according to the demand. The putty should be stirred well in advance, and it should be mixed according to the material and instructions for use of the putty, and a small amount of water should be added to dilute it.

3.Spray putty.

The prepared putty is injected into the spraying equipment and sprayed with a special spray. When spraying, it is necessary to pay attention to the angle and distance of spraying, and maintain a stable spraying speed and thickness to avoid problems such as uneven thickness or crackage of local thickness.

4.Grinding and trimming.

After spraying putty, wait for a certain amount of time for it to dry, and after forming a certain hardness on its surface (depending on the drying time of the putty), it can be sanded. Don't overdo it when sanding to avoid problems such as grinding holes or scratches.

Notes:1During the spraying process of wall putty, it is necessary to pay attention to protect the surrounding items to avoid the splashing of putty.

2.The spraying angle and distance should be appropriate, and the angle and distance of different frontal and inclined planes are different.

3.The spraying speed and thickness should be stable, especially not too thick at once.

4.No matter what kind of wall putty spraying, it is necessary to strictly follow the steps of the product manual.

5.In the process of drying the wall putty, the humidity and ventilation of the room should be controlled.

In the process of wall putty spraying, it is necessary to pay attention to the operation steps and skills of the whole process to avoid problems such as scattered spraying, re-spraying, and paint plugging nozzles. Of course, if you want to spray better quality wall putty, it is best to find a professional decoration company to carry it out.

If you want to make the wall have a better decoration effect, you can passScrape puttyto finish. As a slurry paint, putty can be used to make the wall smoother, which can improve the effect of latex paint, don't ignore it because putty is inconspicuous, it is very important! Next, Zheng Na will learn the steps of scraping putty with us!

Introduction to the steps of scraping putty:

Step 1: Treatment of the base layer of the wall

Different wall base layers have different construction requirements when carrying out base treatment.

For cast-in-place concrete walls, because the wall often has some porosity and bulging phenomenon, it is necessary to repair the wall surface, the protrusion should be smoothed, and the depression should be filled.

For precast concrete floor slabs, there are often some gravel and bumps on the surface, so professional construction personnel need to brush the wall as a whole with a wire brush to remove these debris.

For the cement mortar paper reinforcement ash surface layer, the surface of the wall is required to be dry, solid, clean, and free of oil stains.

Step 2: Repair the base layer of the wall

After the treatment of the wall base layer, there will still be some large wall depressions, so it is necessary to use gypsum putty to preliminarily fill these depressions. When preparing gypsum putty, the weight ratio of gypsum, emulsion and cellulose aqueous solution (concentration 5) is about 100:5:

60. Compact the gypsum putty with a steel scraper in the depression of the wall, and wipe the erected batch scraper again to ensure that the wall is smooth.

Step 3: Brush the caustic alkali aqueous solution

The main purpose of brushing caustic alkali aqueous solution is to clean the oil stain on the concrete wall. If you are using a 5% caustic soda solution, you need to apply it twice, and if you are applying a 10% solution, then you can apply it once.

Step 4: Brush the binder

Before the formal batch of putty, it is also necessary to spray the binder first, and the counterweight ratio of water to binder is about 100:15.

Step 5: Scrape the large white putty

When preparing putty, the weight ratio of large white powder, talcum powder, cellulose aqueous solution (concentration of 5) and emulsion is generally about 60:40:75:

3。When scraping putty, it is necessary to use the steel scraper to connect the wrong batch scraping up and down, left and right, and be sure to avoid leaving floating putty and scratches on the wall, and at the same time, pay attention to prevent the putty from being stained with dust, gravel and other debris.

Step 6: Polishing and repairing

After the first batch of putty is scraped, you need to check whether there is still a problem in the previously repaired area. If there is no problem, after the putty is dry, you need to use fine sandpaper to polish the entire wall, and after sanding, clean the wall. If there are still dents in these parts of the wall, then it is necessary to repair and level again with putty.

Step 7: Putty is finished

The batch scraping of putty generally needs to be carried out two to three times, and the putty of the last pass must wait until the putty of the previous one is completely dry before carrying out the construction operation. After the putty is scraped, the whole wall is required to be smooth and smooth, with uniform texture and no scratches on the surface, otherwise the overall decoration effect will be seriously affected when the latex paint is painted in the later stage.

Steps to scrape puttyThat's it.

1. Traditional putty.

This is the earliest product presented in front of the public, the surface hardness is large after construction, and the cost is low, but because the product contains many harmful residues such as formaldehyde, it is easy to peel off in layers, and it should not be scraped too thick, and it is easy to mildew and moisture, so it has been forcibly banned by the state in July 2002.

2. Water-based putty.

It is gradually accepted by the public after 2002, the hardness is slightly inferior, the cost is about 5 yuan per flat, mildew resistance is good, fast drying, harmful residues are also greatly reduced, but there is still a phenomenon of layered peeling, should not be scraped too thick, belongs to the simple upgrade of traditional putty, rainy days should not be purchased.

3. Cooked rubber ash.

This is the most widely used type of product, less harmful residues, good moisture resistance and mildew resistance, there will be no layered peeling situation, suitable for mending uneven surface, good construction performance, but its surface hardness is slightly inferior, latex paint cover can achieve the best effect, long drying time, cost and price.
