The decoration involves a variety of materials, putty is one of them, is mainly used to level the wall, but also indispensable before the wall paint painting. However, the type of putty is also more, we usually have more to listen to waterproof putty, anti-crack putty, anti-mould putty, etc., then what kind of putty in the end, how to distinguish? Putty, in the end is what?
01 Putty is what?
Putty (filled mud) is a kind of decorative material on the surface of a smooth wall. It is a kind of thick paste coating and is an indispensable product before the paint is painted. Applied to the primer or applied directly to the object to remove the unevenness on the surface of the object. A small amount of lacquer base, auxiliaries, a large number of fillers and a suitable amount of coloring pigments are used for preparation. The pigments used are mainly iron red, Carbon Black and chrome yellow. Fillers are mainly heavy calcium carbonate, talcum powder and so on. The surface can be filled with recessed work surface, but it can also be scraped off on the entire surface, usually after the primer layer is dried, applied on the surface of the primer layer. It requires good adhesion and no cracks during baking. 02 kinds of putty Daquan 1 At present, the market putty putty putty water-resistant putty and general putty is also said that the wall putty. According to the shape can be divided into powder, paste, two-component three: Powder: It is a white powdery product composed of cementitious materials and fillers and additives. Paste: White paste product consisting of synthetic resin emulsion and additive. Two-component: A product consisting of glue and white powder. 2, commonly used putty according to different projects, different purposes can be divided into three categories: plastic old powder putty: made of old powder, chemical glue, gypsum powder, bone glue, used to do water-based paint flat top oily surface putty : It is made of oil base varnish and gypsum powder and used for oily coatings such as steel wood doors and windows. Gel surface putty: made of oil-based varnish, dry powder, chemical glue, gypsum powder, used for the original paint flat top wall surface. 3, putty powder can be divided according to use : wall putty powder and interior wall putty powder. 4, putty powder in accordance with the function can be divided into : waterproof putty, flexible putty, anti-crack putty and so on. 5, according to the chemical composition: single-component putty: polymer + filler (high PVC interior wall coating) multi-component putty: polymer (one-component / two-component) + cement + filler powder putty: cement + filler + Dispersible polymer 03 types of putty introduction:
Cement putty: The putty based on Portland cement is a cement putty, characterized by high strength and high hardness, but the fatal disadvantage is that it is rigid, relatively brittle, and easy to crack. Mainly used for exterior walls (can also be used for interior walls). Its characteristic is the surface strength. Cracking putty: The strength is not so high, but it can resist cracking of the wall and prevent cracks. Water-resistant putty: water-resistant putty is a kind of construction putty, especially to achieve the "building putty" (JG/T3049-1998) standard in the N type, that is, water-resistant putty standard type of putty. "Building putty for indoor use" (JG/T3049-1998) is a minimum standard that must be reached for interior construction putty products. All putty that fails to meet the requirements of the standard is a non-conforming product and is prohibited from being sold and used. Big white putty: that is, we often say that the large white powder, also known as talcum powder, putty powder, is the common material used for leveling the walls in home decoration. Generally, cellulose, white latex and water are added into the large white powder and kneaded into a thick shape. To cover walls and roofs, a layer of interface agent may be applied to the bottom layer to prevent cracking and shedding. Flexible putty: Flexible putty is made of high-quality cement, filler, synthetic polymer, and selective additives. It is divided into ordinary external wall putty, flexible anti-cracking putty and flexible exterior wall according to the flexibility of putty and waterproof performance. Putty and waterproof exterior putty. When using, add 30% water and stir well. It can work normally under the sun exposure weather conditions, it has the advantages of high bond strength, smooth surface, moisture resistance and moisture resistance. It is suitable for substrates such as cement mortar, concrete, gypsum board and Etude 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 fill gaps in the wall surface. Because it has a certain tension, the gap in the wall is affected by the temperature/humidity/external force, and the change will cause no gaps on the wall surface. However, there is still a gap beyond a certain limit, which is white cement + talc + cellulose + 2488 + elastic acrylic emulsion, which is generally used for interior walls of rooms requiring certain musical effects or sound insulation. One of the materials necessary for putty wall decoration is very important for wall decoration, and you can choose different functions of putty according to different needs. The related knowledge of putty types was shared here with everyone and I hope to be helpful to everyone. ...ALL YOU NEED IS BREAD.
