What are the differences between white cement and putty?

putty 

Putty is a substrate used for wall repair and leveling, laying a good foundation for the next step of decoration. Putty is divided into two types: internal wall and external wall. External wall putty needs to resist wind and sun, so it has high adhesive strength and a slightly lower environmental protection index. The comprehensive index of interior wall putty is good, healthy and environmentally friendly, so interior walls are not used externally and exterior walls are not used internally. Usually, putty is made of gypsum or cement-based materials, which makes it easier to bond firmly with a rough surface. However, during construction, it is still necessary to apply a layer of interface agent on the base layer to seal the base layer and improve the adhesion of the wall, so that the putty can better bond to the base surface.

White cement

White Portland cement is abbreviated as white cement. It is a hydraulic cementing material made by adding white Portland clinker to gypsum and grinding it. It is a kind of cement, but it has higher grade than ordinary Portland cement and sets faster. White cement is mostly used for decoration, and its manufacturing process is much better than ordinary cement. Mainly used to hook gaps in white porcelain tiles, generally not used on walls due to low strength. Available in building materials markets or decoration material stores.

The difference between putty and white cement

1. White cement is mainly composed of minerals such as calcium carbonate. Calcium carbonate is an alkaline salt that neutralizes when exposed to acid. Over time, it weakens. White cement itself becomes very hard after air drying, and when the hardness reaches a certain level, it will crack itself, which is why many walls crack.

2. Putty itself also contains white cement, but it not only contains white cement, but also polymers such as acrylic acid emulsion. Nowadays, most high-rise buildings must use putty because its cost is similar to that of white cement and adhesive, but its quality is vastly different. From alkali resistance to crack resistance to acid resistance, etc., it is significantly superior to white cement!
