Surface preparation is vital before applying a finish. The removal of dust, grease and rust will ensure a smooth surface to adhere to. Some finishes require better grip and need something to key to so the surface is left rough. Fabrics require rinsing before dyeing to remove chemicals in the raw fabric.
Surface finishes can be applied in a variety of ways
Painting and rolling
Spraying
Electroplating
Adhesives
Sandblasting
Heating or pressure bonding
Printing
