What is scraping putty and what material is used to scrape putty

The number of times to scrape putty is determined by the flatness of the wall, which is generally twice.

The first time, when the putty is scraped, the rubber scraper is scraped horizontally, a scraper is followed by a scraper, the joint shall not be left behind, and the final end of each scraper should be clean, smooth, to achieve flat, uniform, smooth, and do not leave the joint, after the putty is dry, it shall be smoothed and polished with sandpaper, and there shall be no scratches. Sweep the powder clean after polishing. Then carry out the second full scraping putty, and the second time should be vertically full scraping, the same as the first one.

The foundation of indoor wall decoration, after cleaning the wall, scrape putty (a decorative material), and strive to be smooth and uniform!

Scrape the putty on the wall to ensure that the wall surface is flat. Generally, scrape three times, and after drying, polish it with sandpaper. This step is carried out before the latex paint is applied.

My house has just finished decorating, is a layer of white things on the surface of the muddy water, this kind of thing is made of putty powder with water and glue mixed together, putty powder is divided into exterior wall putty powder and interior wall putty powder, interior wall putty powder has a strong waterproof function, so interior wall putty powder generally can not be used on the exterior wall, and exterior wall putty powder can be used on the interior wall,

There are many kinds of putty on the wall, and the putty paste on the northeast side is commonly known as Dabai, which is used to stabilize the wall and lay the foundation for brushing latex paint.

And then there's wood paint, and if you paint the wood with oil, you need to hit the putty again, and this putty is not the kind of wall.

It is used to stabilize wood as brush oil.

Scraping white powder on the wall is scraping putty.

It is to put a white base on the wall.

Nowadays, there are many wall decoration materials on the market, and putty is one of them. So the question is, do you know what material is used to scrape putty? What are the key points to pay attention to when scraping putty? Next, let me give you a brief introduction.

1. Gypsum-based putty.

The main function of wall putty is to fill the wall base, protect the wall, beautify the environment and improve the physical properties of the wall finishing material. Gypsum putty can be used by stirring with water, without the use of glue, so it is very environmentally friendly, and there will be no cracking, peeling and other phenomena.

The main reason for the low application of gypsum putty on the market today is that the performance advantages of the material are not fully appreciated. Only by adding functional additives to the gypsum-based putty, the putty film can produce functionality, such as hygroscopicity, negative ion release function, etc., which has been paid attention to and studied.

2. Cement-based putty.

Although cement-based putty has good workability and water resistance, high bond strength and is not easy to age, the cost is high, and it takes seven months for the cement-based to really dry, while the gypsum base only needs 3 to 5 days. Therefore, whether in terms of constructability or appearance after construction, gypsum base is better than cement base.

3. Cooked glue old powder.

Cooked gum powder, which is made by special treatment and drying of potato starch, is a kind of modified starch. Cooked rubber powder is its trade name, because it dissolves in cold water, so it is called cooked rubber powder. At present, the more common cooked rubber powder on the market is esterified and etherified modified starch, which can be dissolved in cold water, strong adhesion, non-toxic and tasteless, is a green and environmentally friendly adhesive, and is widely used in the construction industry.

Key points of putty scraping.

1. If you used to paint lime or paint, and now you want to paint latex paint, then you must first remove the original wall and scrape the putty again.

2. If you want to paint a colored room, it is recommended to buy latex paint with color directly. If you want to redeem it yourself, you must redeem it all at once, otherwise there will be color difference. Of course, the gradual color difference is also a decorative effect.

3. The quality of the roller brush should be good, and the hair quality should be moderate and evenly densified, otherwise it will affect the painting effect.

4. Paint the ceiling first, then the wall.

6. Uniform force.

Summary: After reading the above introduction, I believe you have a further understanding of what materials are used to scrape putty. If you need to know more about it, please continue to ******, and more exciting content will be presented to you in the future.

Scraping putty refers to the most important step in the treatment of the base layer by filling or overall treatment to remove the uneven part of the surface of the base layer and keep the Tongxiao wall smooth and smooth.

Apply to the primer or directly to the object, and use a stool to remove uneven defects on the surface of the coated object. It is prepared with a small amount of lacquer base, a large number of fillers and an appropriate amount of coloring pigments, and the pigments used are mainly iron red, carbon black, chrome yellow, etc.

The fillers are mainly calcium bicarbonate, talcum powder, etc. It can be used to fill partially recessed work surfaces, or to scrape off the entire surface, usually after the primer layer has dried, and then apply to the surface of the primer layer. Good adhesion and no cracks are required during the baking process.

Key points of operation of scraping putty:

1. If you originally brushed lime or paint, if you want to brush latex paint, you must first remove the original wall and scrape the putty again.

2. If you want to paint a colored room, you can directly buy latex paint with color, if you redeem it yourself, you must redeem it at one time, otherwise there is a color difference, of course, the gradual color difference is also a decorative effect.

3. The quality of the roller brush must be good, the hair quality is moderate, and the density is uniform, which affects the painting effect.

4. Paint the ceiling first, then the wall.

5. Be sure to dry it for the first time and brush it again again.

6. Uniform force.

7. Brush the light color 2 times, if you want a strong color, brush it 3 times to be even.

Scraping putty is a way of interior wall decoration, most of them are scraping putty before preparing to make latex paint, and at least scrape more than twice, and so on after the putty is dry, sandpaper should be used to polish smooth, scraping putty is able to fill the position of the wall potholes, improve the uneven part of the wall, so as to ensure that the inner wall looks more smooth and smooth, so scraping putty can be said to be an important step in the wall treatment, Before scraping, the wall should be cleaned, and there should be no potholes, otherwise it will affect the beauty of the wall.

Putty powder is a kind of building decoration material, and the main components are talcum powder and glue.

Usually the whiteness of putty is above 90 and the fineness is above 330. Putty is a substrate used for wall repair and leveling, laying a good foundation for the next step of decoration.

Putty is divided into two types: interior wall and exterior wall, and the exterior wall putty should resist wind and sun, so it has high gelatinity, high strength, and slightly lower environmental protection index. The comprehensive index of interior wall putty is good, healthy and environmentally friendly, so the interior wall is not used externally, and the exterior wall is not used internally. Usually putty is gypsum or cement-based, so that the surface is rough and it is easier to bond firmly.

However, during construction, it is still necessary to apply a layer of interface agent on the base layer to seal the base layer and improve the adhesion of the wall, so that the putty can be better bonded to the base surface.

Composition of putty

Putty is generally composed of base material, filler, water and additives.

The binder, also known as the binder, is the most critical component of putty, mainly playing various roles such as bonding. The most commonly used binders for putty are cement and organic polymers, which are also divided into emulsions and latex powders, which can be modified and toughened to improve the performance of putty.

Fillers mainly play a filling role, and commonly used are calcium carbonate, talcum powder and quartz sand. Attention should be paid to the combination of packing fineness.

Additives include thickeners, water retention agents, etc. Thickeners and water-retaining agents play the role of water retention, improve storage and construction performance, and cellulose is generally used. Antifreeze is mainly used to improve the storage stability of putty at low temperature, and slippery agents and water reducers are generally used in high-grade putty to improve the construction performance of putty.

1. Scraping putty is one of the methods of interior wall decoration, scraping putty on the wall to ensure that the wall is smooth. Generally, scrape three times, and after drying, polish it with sandpaper. This step is carried out before the latex paint is applied.

Yes, but you should pay attention, 1It should be noted that after the first putty is scraped and completely dry, it needs to be carefully sanded with sandpaper to clean up the surface dust before you can start to scrape the putty for the second time. If the putty is scraped for the second time without drying, the moisture content of the wall is large, which may cause the wall to blister, yellow, and fall off.

2.The wall is completely dry, and visually speaking, the color of the entire wall is uniformly white, and there is no graying feeling when wet. Gently stroke it with your hand, it feels very smooth and will be slightly stained with a little dust.

Or use sandpaper to gently sand, a large amount of dust appears, it means that the first layer of putty has been dried, less dust or basically no dust, it means that the first putty scattered draft has not dried thoroughly. The drying time of putty should be adjusted according to different climatic conditions, and the drying time needs to be extended in dark and humid climates. Under normal circumstances, the position of the yin corner is the most difficult to dry out, if the position of the yin corner is dry, then it can be basically judged that the whole wall has been dry.
