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: interior wall putty and exterior wall putty. Exterior wall putty needs to resist wind and sun exposure, so it has high adhesiveness, high strength, and slightly lower environmental protection index. The comprehensive index of putty for interior walls is good, which is healthy and environmentally friendly, so it is not used externally for interior walls and not used internally for exterior walls. 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.

White cement

White Portland cement, abbreviated as white cement. It is a hydraulic cementitious material made by adding white Portland cement clinker to gypsum and grinding it finely. It is a type of cement, but has a higher grade than ordinary Portland cement and sets faster. White cement is mostly used for decorative purposes, and its manufacturing process is much better than ordinary cement. It is mainly used to hook the gaps of white porcelain tiles and is generally not used on walls because of its low strength. It is available for sale in building materials markets or decorative material stores.

The difference between putty and white cement

1. White cement is mainly composed of minerals such as calcium carbonate. Calcium carbonate is a basic salt that reacts with acid to neutralize and eventually weather away. White cement, on its own, becomes very hard after air drying, and when its hardness reaches a certain level, it will crack. This is the reason why many walls crack.

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