Some homeowners have reported that the walls in their homes are the most primitive gray cement walls. When renovating, some workers introduced the construction process and said that they need to use one layer of white cement first, then two layers of putty powder, and then two layers of topcoat. The owner feels that using white cement is not good and wants to use putty powder entirely. However, the worker said that white cement is more expensive and better than putty powder. Pinhe Exchange Home helps everyone popularize the characteristics of white cement and putty powder substrates for wall surfaces.

1. White cement is the abbreviation for white Portland cement, which is obtained by burning raw materials with appropriate composition until partially melted, and the main component is calcium silicate. We know that calcium carbonate belongs to basic salts, which will undergo neutralization reaction when exposed to acid. Over time, it will weather and produce phenomena such as peeling and detachment of walls. When grinding cement, it is allowed to add limestone not exceeding 5% of the weight of cement.

Characteristics: 1) White cement is mostly used for decorative purposes, and its manufacturing process is much better than ordinary cement.

2) White cement is very hard after being air dried, and once its hardness reaches a certain level, it will crack, which is the reason why many walls crack.

2. Putty powder is a type of building decoration material, mainly composed of talcum powder and glue. It also contains components of white cement, but it not only contains white cement, but also polymers such as propylene emulsion. The whiteness of putty is usually above 90 and the fineness is above 330.

Characteristics: 1) Putty is a substrate used for wall repair and leveling, laying a good foundation for the next step of decoration (painting, pasting wallpaper). Usually, putty is made of gypsum or cement-based material, which makes the surface rough and easier to bond firmly. However, during construction, it is still necessary to apply a layer of interface agent on the base to seal the base and improve the adhesion of the wall, so that the putty can better bond to the base. 2) Its cost is almost the same as that of white cement+glue, but its quality is vastly different. From alkali resistance to crack resistance and acid resistance, it is significantly superior to white cement! For home decoration, it is recommended to use putty powder, which can be mixed with water and is very environmentally friendly.
