Preparation of steel substrates before application of paints and related products. Visual assessment of surface cleanliness -- Rust grades and preparation grades of uncoated steel substrates and of steel substrates after overall removal of previous coatings
Preparation of steel substrates before application of paints is a crucial step to ensure proper adhesion and durability of the coating.
It involves several processes including cleaning, removing rust, and smoothing the surface.
Cleaning typically involves the removal of oil, grease, dirt, and other contaminants using solvents or detergents.
Rust removal can be done through methods such as abrasive blasting, wire brushing, or chemical treatments.
Smoothing the surface may include grinding or sanding to create an even texture that facilitates better paint adhesion.
