    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing the correct grit sequence when sanding, leading to poor adhesion or surface damage.
    • Failing to properly drain moisture from compressed air systems, causing defects like fisheyes or solvent pop in paint finishes.
    • Selecting incorrect refinishing materials for the substrate (e.g., using a primer not suited for aluminum), which can result in paint failure.
    • Neglecting to follow safety protocols when using isocyanate-containing paints, risking health hazards.
    • Confusing air tool lubrication requirements, leading to premature wear.
    • Neglecting to drain moisture from compressed air lines, causing contamination in the finish.
    • Selecting incorrect abrasives, resulting in improper surface preparation.
    • Failing to consult technical data sheets when choosing refinishing materials.
    • Assuming all substrates can be prepared and refinished using identical techniques, ignoring specific requirements for aluminium or GRP.
    • Neglecting to adjust air pressure at the gun inlet rather than at the compressor, leading to inconsistent spray patterns.
    • Failing to check for oil or water contamination in the air supply before spraying, causing film defects.
    • Incorrectly disposing of solvent-soaked rags without regard for spontaneous combustion risk.
    • Failing to properly clean and maintain spray guns, leading to irregular spray patterns or paint defects.
    • Using incorrect air pressure settings, which can result in poor atomization, orange peel, or excessive overspray.
    • Neglecting to degrease and prepare surfaces thoroughly before applying refinishing materials, causing adhesion failures.
    • Confusing the refinishing requirements for different substrates, such as applying direct-to-metal paint on plastic without proper adhesion promoters.
    • Misconception: More paint layers always give a better finish. Correction: Too many layers can lead to runs, sagging, or cracking. Follow manufacturer guidelines for film thickness.
    • Misconception: Sanding is only for removing old paint. Correction: Sanding is also essential for creating a key (rough surface) for new paint to adhere, even on bare metal.
    • Misconception: You can skip degreasing if the surface looks clean. Correction: Even invisible contaminants like silicone or wax can cause fisheyes or poor adhesion. Always degrease before painting.
