The difference between putty paste and putty powder has its own advantages
Putty powder plays a very important role in the decoration. Because of the large shrinkability of the putty powder, the base layer must be firmer. In addition, there are problems with the operation of the putty powder in the actual construction, which can easily lead to quality accidents. Putty powder appears to be peeling and peeling. The next Xiaobian for everyone to introduce the difference between putty paste and putty powder.
The difference between putty paste and putty powder
1. Common putty: powdered putty made of plant-type dispersible rubber powder, modified starch, methyl cellulose or carboxymethyl cellulose, talcum powder, and fly powder as main raw materials, and the trade name is mostly 821 Putty powder, use water modulation. With high whiteness, easy scraping, easy grinding, low price, but low bonding strength, poor water resistance. Only suitable for general building indoor dry room as a putty for paint decoration, not suitable for decorative wallpaper.
2. Indoor powdery water-resistant putty: powdered putty made of plant-type dispersible rubber powder, white cement, talcum powder or fly-powder powder, and cellulose (water-retaining agent) as main raw materials, and is added with water when used. It has good water resistance, high bond strength, no powder falling off, no cracking, no falling off, etc., and can be applied on wet walls. It is suitable for the decoration of walls and ceilings in various indoor humid environments.
3, indoor paste waterproof putty: white latex, talcum powder, fly powder, methyl cellulose (water retention agent) as the main raw material made of paste putty, can be used directly. It has good moisture resistance, high whiteness, and it is not easy to peel, crack or fall off after moisture. Suitable for all types of construction of the living room, kitchen, bathroom and other basic treatment of the wall and ceiling, but does not apply to occasions often have water, water resistance is not as good as cement-based putty.
4. Stucco gypsum series products: Powdered materials made of mixed-phase hemihydrate gypsum, retarder, and additives as the main raw materials, and added with water when used. It can be used as a plastering layer or as a bottom putty. It can be firmly bonded to substrates such as cement, concrete, aerated concrete, foamed polystyrene board, and thermal insulation mortar. With no hollowing, no fall off, slight expansion, inhibit cracking, hardening fast and so on. Suitable for plastering and leveling of walls and ceilings of different materials in the room.
5. External wall powdery putty: powdery putty made of plant-type dispersible rubber powder, white cement, talcum powder and cellulose as the main raw materials, and is prepared by adding water when used. It has the characteristics of high bond strength, no emptying, no shedding, water resistance and weather resistance. Applicable to the leveling of exterior wall surfaces of buildings.
6, flexible two-component exterior putty: two-component putty made of acrylic emulsion, rubber powder, additives, white cement, talcum powder, cellulose as the main raw material, a group is divided into powdery bags, another The components are barrels of milky white liquid. When used, the two components are proportioned. With a certain degree of flexibility, it can overcome the cracks in the exterior wall decoration, and has the characteristics of high bonding strength, no emptying, no falling, water resistance, and weather resistance. Applicable to the leveling of exterior wall surfaces of buildings.
7. Flexible powdery exterior wall putty: powdered putty made of dispersible rubber powder with elasticity, white cement, talcum powder and cellulose as the main raw materials, and added with water when used. It has the characteristics of high bond strength, early dryness without cracking, no emptying, no shedding, water resistance, and weather resistance. Applicable to the leveling of exterior wall surfaces of buildings.
Putty powder use matters needing attention
1, in order to make the overall wall surface better, putty powder can be used to apply multiple times, so that the wall can be more smooth.
2, when leveling, if the putty scraping, in a semi-dry state, you can use the tool for leveling, if it has been cured, you can use the emery cloth to level.
3, when saving, pay attention to waterproof, moisture. Storage period is six months.
4, the construction temperature above 0 °C, putty powder into a paste should be used within 4-5 hours to avoid prolonged deterioration.
5, putty powder can not be used with other putty in the same construction surface, so as not to cause chemical reactions and color.
Editing summary: The difference between putty paste and putty powder is introduced here, and we hope to be helpful to everyone. If you want to know more about yourself, you can follow the information on this site.
