Architectural coatings have decorative functions, protection functions and habitability improvement functions. The proportions of various functions vary depending on the purpose of use. The decoration function is the function of enhancing the appearance value of the building through the beautification of the building. It mainly includes the conceptual design of plane colors, patterns and gloss, and the conceptual design of three-dimensional patterns. But it must be matched with the shape of the building itself and the size and shape of the base material itself to be fully utilized.

The protection function refers to the function of protecting the building from the influence and destruction of the environment. Different types of protected objects have different requirements for protection functions. For example, the requirements for indoor and outdoor coating are very different. Some buildings have requirements for fire prevention, thermal insulation, and corrosion resistance.

The habitability improvement function is mainly for the indoor coating, which is the function that helps to improve the living environment, such as sound insulation, the function and classification of sound-absorbing coatings, and anti-condensation properties.

The function of coating is to decorate and protect, protect the surface of the coated object, prevent the corrosion from outside light, oxygen, chemical substances, solvents, etc., and increase the service life of the coated object; paint the surface of the coating material, change its color, pattern, Luster, texture, etc., improve the aesthetic value of objects.

1. Mainly based on the use of coating products as the main line, supplemented by the classification method of the main film-forming substances. The coating products are divided into three main categories: architectural coatings, industrial coatings and general coatings and auxiliary materials.

2. In addition to architectural coatings, the main film-forming substances of coating products are the main line, and the classification method of the main purpose of the product is appropriately supplemented. The coating products are divided into two main categories: architectural coatings, other coatings and auxiliary materials.

In the above two classification methods, architectural coatings are divided into wall coatings, floor coatings and functional architectural coatings.

Architectural coatings: coatings applied to buildings, decorative buildings or protective buildings, collectively referred to as architectural coatings.
