You all might have come across building which have architectural coatings done on them. This architectural steelwork on the metal surfaces not only beautifies them from the outside but also makes from strong and durable too. A strong coating on your metals will help it fight from the outside weather and act as shield protecting them from rain, direct sunlight, pollution, etc.
The architectural coating consists of four major constituents which are pigment, solvent, additives and binders. These constituents help in making the coatings strong so that the inner layers of the metal can be kept safe and secure. All four constituents serve different purposes. For example, pigment is a layer which is used to hide the base which is mixed with solvent. This solvent helps in the smooth flow of the paint on the surface. Spray application and manufacturing of the coatings is made easy with the help of additives and binders work to bind together all these materials before application.
These architectural systems can be used for other purposes too apart from steelwork such as for curtain walling repairs, etc. It consists of four major systems. These systems are primers, build coats, under coats and top coats. While primers are meant to protect the substrate from corrosion and are labelled according to the metals that they have in them such as iron oxide, zinc phosphate, etc. The next system is the build coat which has additives and therefore adds thickness to protect the metal. The under coat serves as the base colour. This makes sure that the top colour does not change due to a different base. The final layer is called as the two- pack or a single pack paint and is used to increase the aesthetic view of the building. This forms the final layer of the architectural metalwork and decides the final appearance of the building.
