Architectural coatings are the coatings for architectural steelwork which not only increase the beauty of your buildings but also act as shield against various kinds of environmental factors such as dirt, dust and pollution. There are a few constituents and systems of architectural coating, let’s discuss them.

The architectural coating has four major constituents and they are pigment, solvent, additives and binders. Component of primer and paint, pigment consists of small particles which helps in hiding the flaws of the surfaces such which has to be painted such as the curtain walls in the form of curtain wall spraying, etc. It acts as decorative layer and also acts as shield protecting the surface from corrosion. Solvent is the liquid in which the pigment and other substances are mixed and dissolved. This makes the flow of paint smooth and easy. Additives are yet another material added to the mixture which acts as a coating which aims to prevent the growth of mould on the surface and also adds gloss to protect the surface from environmental harshness. Last but not the least are the binders. These binders act as a medium which binds together all the components together. It consists of oil, resins, vinyl and other such different kinds of polymers.

There are four major systems of architectural coatings which are primers, build coats, under coats and top coats respectively. All these coatings have different uses and aid in the flawless application of the paint over the surface. These coatings serve the purpose of protecting the surface as well as the paint from sun, rain, dirt, dust and pollution by wall or glass spraying and at the same time they also increase the life of the building.
