Types and introduction of putty
There are many kinds of materials involved in the decoration. Putty is one of them. It is mainly used to level the wall surface, and it is also indispensable before the wall paint is painted. However, there are many types of putty. Everyone usually listens to waterproof putty, anti-cracking putty, anti-mite putty, etc. How much is the type of putty, how to distinguish it? Master Zhong is a honest and honest Decoration painter, but very familiar with the putty material, we also come to understand: What is putty? Putty (filled mud) is a kind of decorative material that flattens the surface of the wall. It is a kind of thick slurry coating, which is an indispensable product before painting. Apply to the primer or directly to the object to remove the unevenness on the surface of the object. It is prepared by using a small amount of paint base, additives, a large amount of filler and an appropriate amount of coloring pigment. The pigments used are mainly iron red, carbon black, chrome yellow and the like. The filler is mainly calcium bicarbonate, talc, and the like. It can fill the working surface with partial depression or scrape off the entire surface, usually after the primer layer is dry and applied to the surface of the primer layer. It requires good adhesion and no cracks during baking. The type of putty is: 1. At present, the putty varieties sold on the market have water-resistant putty and general-type putty, which is also known as the wall putty. According to the shape, it can be divided into powder, paste and two components: Powder: It is a white powdery product consisting of cementitious materials and fillers and additives. Paste: A white paste product consisting of a synthetic resin emulsion and an additive. Two-component: a product consisting of a glue and a white powder. 2. Commonly used putty can be divided into three categories according to different engineering projects and different uses: Glue old powder putty: made of old powder, chemical glue, gypsum powder and bone glue, used for water-based paint flat top Oil-faced putty: It is formulated from oil-based varnish and gypsum powder and is used in oil-based coatings such as steel-wood doors and windows. Glue putty: It is made of oil-based varnish, dry old powder, chemical glue and gypsum powder. It is used for the flat top wall of the original paint. 3. Putty powder can be divided into: external wall putty powder and interior wall putty powder according to the use. 4, putty powder according to the function can be divided into: waterproof putty, flexible putty, anti-cracking putty and so on. 5. According to the chemical composition: One-component putty: polymer + filler (high PVC interior wall coating) Multi-component putty: polymer (single component / two component) + cement + filler Powder putty: cement + filler + dispersible polymer Introduction to the type of putty: Cement putty: Putty based on Portland cement is cement putty, characterized by high strength and high hardness, but the fatal disadvantage is that it is rigid, brittle and easy to crack. Mainly used for exterior walls (also for interior walls). It is characterized by a large surface strength. Anti-cracking putty: the strength is not so high, but it can resist wall cracking and prevent cracks. Water-resistant putty: Water-resistant putty is a kind of construction putty, especially a kind of putty that can reach the N-type, that is, the water-resistant putty standard in the standard for building interior putty (JG/T3049-1998). "Building Interior Putty" (JG/T3049-1998) is a minimum standard that must be achieved in indoor building putty products. All putty that does not meet the requirements of this standard is a non-conforming product and is prohibited from being sold and used. Dabai putty: It is the white powder we often say, also known as talcum powder and putty powder. It is a common material for leveling the wall in home decoration. Generally, cellulose, white latex and water are added to the white powder, and it is thickened. Used to cover the wall surface and roof, to prevent cracking and falling off, a layer of interface agent can be applied to the bottom layer. Flexible putty: The flexible putty is made up of high-quality cement, filler, synthetic polymer and selected additives. It is divided into ordinary exterior wall putty, flexible anti-cracking putty and flexible exterior wall according to the flexibility and waterproof performance of putty. Putty and waterproof exterior wall putty. Add 30% water and mix well when using. It can be normally constructed under the weather conditions of sun exposure, and has the advantages of high bonding strength, smooth surface, water and moisture resistance. Suitable for substrates such as cement mortar, concrete, gypsum board and Ette board, as well as exterior wall surfaces of various buildings. Elastic putty: The meaning of "elasticity" is that there is a certain tension. The elastic putty is mainly used to find the gap of the wall surface. Because it has a certain tensile force, the gap in the wall is affected by the temperature/humidity/external force, and the wall surface does not have a gap. However, there will be gaps beyond a certain limit. It is white cement + talcum powder + cellulose + 2488 + elastic acrylic emulsion, which is generally used for interior walls of rooms that require certain musical effects or sound insulation. One of the essential materials for the wall decoration of putty has a very important role in wall decoration, and can choose different functions of putty according to different needs. The knowledge about the type of putty is shared with you here. I hope to help you. For more information, please pay attention to the WeChat public account of Jiuzheng Coatings.
