Coatings, traditionally referred to as paints in china. The book of coating technology which is relatively authoritative in the Chinese coating world is defined as follows: the paint is a material which can be coated on the surface of an object by different construction processes to form a continuous solid film with firm adhesion and certain strength. The film thus formed is generally called a coating film, also called a paint film or a coating. The wall surface coating is an application and wide coating, and mainly aims to be used for decorating and protecting building wall surfaces, so that the building wall surfaces are attractive and tidy, and meanwhile, the wall surface coating can also play a role in protecting the building wall surfaces and prolonging the service life of buildings. The wall surface coating comprises an inner wall coating and an outer wall coating according to the classification of building wall surfaces. The interior wall coating emphasizes decoration and environmental protection; exterior wall coatings focus on protection and durability.
