The metal-sprayed coating is in itself a complete protective system for iron or steel structures. The use of sealant, however, enhances this protection and also produces a pleasing appearance.
It penetrates and fills the pores, thus reducing the total area of the exposed metal and therefore, the rate of dissolution of the coating.
It smoothes the surface texture preventing the retention of grime and other contaminants, thus reducing still further the rate of surface attack
By smoothing the surface texture the appearance of the coating will remain cleaner and more attractive than without a sealant.
Spray painting is a painting technique where a device sprays a coating (paint) through the air onto a surface
A basic spray painting system consists of a conventional spray painting gun, a pressurized paint container, a compressed air system, and flexible tubes connecting them all together
This process occurs when paint is applied to an object through the use of an air-pressurized spray gun. The air gun has a nozzle, paint basin, and air compressor. When the trigger is pressed the paint mixes with the compressed air stream and is released in a fine spray.
The coating penetrates better into pits and crevices
A uniform thick coating is produced, reducing the number of coats required
A very “wet” coating is applied, ensuring good adhesion and flow-out.
