Putty is a decorative material for leveling the wall surface. It is a thick paste paint and an essential product before paint painting. Apply it on the primer or directly on the object to remove the uneven defects on the surface of the object. It is prepared with a small amount of paint base, additives, a large amount of fillers and an appropriate amount of coloring pigments. The pigments used are mainly iron red, carbon black, chrome yellow, etc

as we all know, putty is a decorative material for leveling the wall surface to remove uneven defects on the wall surface. However, there are several kinds of putty used in home decoration, the most common of which are gypsum based putty, cement-based putty, mature glue powder, etc. The following editor will introduce the types of putty and the role of putty powder

types of putty

1. Cement putty: the putty based on Portland cement is cement putty, which is characterized by high strength and hardness, but its fatal disadvantage is that it is rigid, brittle and easy to crack. It is mainly used for external walls (or internal walls), which is characterized by high surface strength

2. Crack resistant putty: the strength is not so high, but it can resist wall cracking and prevent cracks

3. Water resistant putty: water resistant putty is a kind of building putty, especially a kind of putty that can meet the n-type in the standard of putty for indoor use in buildings, that is, the standard of water-resistant putty. "Putty for indoor use in buildings" is a minimum standard that must be met by indoor building putty products at present. Therefore, putty that fails to meet the requirements of this standard is unqualified products, and it is forbidden to sell and use

4. Big white putty: we often say big white powder, also known as talc powder and putty powder. It is a common material for wall leveling in family decoration. Generally, cellulose, white emulsion and water are added to the big white powder and kneaded into a thick form to batch the wall surface and roof. In order to prevent it from cracking and falling off, a layer of interface agent can be applied to the bottom layer

5. Flexible putty: flexible putty is composed of high-quality cement, fillers, synthetic polymers and selected additives. According to the flexibility and waterproof performance of putty, it is divided into ordinary exterior wall putty, flexible crack resistant putty, flexible exterior wall putty and waterproof exterior wall putty. When in use, add 30% water and stir evenly. It can work normally in sunny weather, and has the advantages of high adhesion, smooth surface, water resistance and moisture resistance. It is applicable to the base materials such as cement mortar, concrete, gypsum board and Aite board, as well as the external walls of various buildings

6. Elastic putty: “ Elasticity ” It means that there is a certain tension. Elastic putty is mainly used to repair the wall cracks. Because it has a certain tension, the wall cracks are affected by temperature, humidity, external forces, etc. And then change, the wall will not appear cracks. However, there will be cracks beyond a certain limit. It is white cement + talc powder + cellulose + elastic acrylic lotion, which is generally used in the interior walls of rooms that require a certain musical effect or sound insulation

precautions for puttying

1. In order to have a good effect, it is best to apply a layer of primer before puttying

2. When applying putty, the inclination of the tool should be controlled and the application should be uniform

3. In order to avoid cracking and falling off of putty, do not scrape it too thick, and properly control it according to the different types of putty. The thickness is generally about 0.5-1mm

4. Do not repeat scraping too much

function of putty powder

1. Beautification function

in the coating engineering, users require that the wall surface is not only flat, but also smooth and delicate. In particular, some paints have higher requirements for the smoothness of the wall. To improve the smoothness, the performance of putty base must be improved

2. Overcoming turtle cracks

on the surface of buildings, especially the outer wall, there are often surface fine cracks caused by the shrinkage of cement, in the form of turtle back, so it is called “ Turtle crack ” Turtle cracks often cause the coating to shell, fall off, and even cause water seepage on the wall. Therefore, the anti self cracking and anti cracking of the putty layer are important indicators of the putty quality, and also the technical research and development focus of the putty manufacturer

3. Filling effect

leveling is the most basic requirement for coating, so filling is a basic function of putty. Irregularities can be found everywhere during construction. For example, the unevenness of the cement mortar surface, the unevenness of some walls, or the general undulation of the ceiling under the light, affect the beauty of the building
