What is the difference between scraping imitation porcelain and scraping putty? Be specific.

1, scraping putty refers to the treatment of putty powder on the wall. Scraping porcelain refers to covering the surface with latex paint after putty powder is finished. Scraping porcelain is a kind of wall treatment. The wall treated with imitation enamel is waterproof, but it is rarely used now.

2. These two processes are wall treatment. But people are used to it, which refers to wall covering and surface treatment.

These are two different decoration steps. Blow putty to level the wall, and then brush latex paint.

4. The materials are all adjusted by the material manufacturer in advance, and the porcelain scraper does not need to adjust it himself. Imitation porcelain is not diluted with water, but made of a chemical glue.

Extended data

Scraping imitation porcelain (English name: Scraping ceramic) is a kind of porcelain, which is used for painting and wallpaper decoration.

Decoration putty can be divided into powder and paste, one-component and two-component; According to the performance, it is divided into water-resistant putty, flexible putty and common putty; According to the base material, it is divided into cement type, gypsum type and stone powder type. Commonly used decorative putty has the following kinds:

1. Ordinary putty: powder putty made of water-soluble resin or modified starch, methyl cellulose or carboxymethyl cellulose, talcum powder and Shuangfei powder. The trade name on the market is 82 1 putty powder, which is mixed with water when used.

It has the characteristics of high whiteness, easy scraping, easy polishing and low price, but it has low bonding strength and poor water resistance. It is only suitable for indoor dry rooms of general buildings as putty for paint decoration, not for wallpaper decoration.

2. Indoor powdery water-resistant putty: a powdery putty made of water-soluble resin or redispersible latex powder, white cement, talcum powder or Shuangfei powder and cellulose (water retaining agent) as the main raw materials, which is mixed with water when used. It has the characteristics of good water resistance, high bonding strength, no powder loss, no cracking and no shedding after being wetted, and can be used for wet wall construction. It is suitable for the decoration of walls and ceilings in various indoor humid environments.

3. Indoor water-resistant putty: paste putty made of white latex, talcum powder, Shuangfei powder and methyl cellulose (water retaining agent) can be directly used. It has the characteristics of good moisture resistance, high whiteness, no peeling, no cracking and no shedding after being wetted.

It is suitable for the basic treatment of walls and ceilings in bedrooms, kitchens, bathrooms and other buildings, but it is not suitable for occasions where there is often water, and its water resistance is not as good as that of cement-based putty.

4. Plastering gypsum series products: powder materials made of miscible gypsum hemihydrate, retarder and additives, which are mixed with water when used. It can be used as plastering layer and bottom putty, and it is firmly bonded with cement, concrete, aerated concrete, foamed polystyrene board, thermal insulation mortar and other substrates. It has the characteristics of no hollowing, no shedding, slight expansion, cracking inhibition and rapid hardening.

Suitable for plastering and leveling indoor walls and ceilings with different materials.

5. Exterior wall powder putty: powder putty made of redispersible latex powder, white cement, talcum powder and cellulose as main raw materials and mixed with water when in use. It has the characteristics of high bonding strength, no hollowing, no shedding, water resistance and weather resistance. Suitable for leveling external walls of buildings.

6. Flexible two-component exterior wall putty: a two-component putty made of acrylic emulsion, additives, white cement, talcum powder and cellulose as the main raw materials, one group is divided into powder bags, and the other group is divided into milky white liquid barrels. When in use, the two components are mixed in proportion. It has certain flexibility, can overcome the cracking of exterior wall facing, and has the characteristics of high bonding strength, no hollowing, no shedding, water resistance and weather resistance. Suitable for leveling external walls of buildings.

7. Flexible exterior wall putty: Powdered putty made of elastic redispersible latex powder, white cement, talcum powder and cellulose, which is mixed with water when used. It has the characteristics of high bonding strength, no cracking at initial drying, no hollowing, no shedding, water resistance and weather resistance. Suitable for leveling external walls of buildings.

Putty scraping is one of the methods of interior wall decoration. Scrape putty on the wall to ensure that the wall is flat. Generally scrape it three times, dry it and polish it with sandpaper. This step is carried out before applying latex paint.

Putty scraping is the most important step in base treatment, which means to remove the uneven part of base surface and keep the wall flat by filling or integral treatment.

Putty (filled with mud) is a decorative condensation material for leveling walls, a thick slurry coating and an essential product before painting. Apply it on the primer or directly on the object to remove the uneven surface of the coated object.

It is made of a small amount of paint base, a large amount of filler and a proper amount of colored pigment. The main pigments used are iron red, carbon black and chrome yellow. The fillers are mainly heavy calcium carbonate and talcum powder. It can fill the local depression on the working surface or scrape off the whole surface, and usually it is coated on the surface of the primer layer after it is dried. It is required to have good adhesion and no crack during baking.
