Spray painting agricultural plant and machinery


Spray painting agricultural plant and machinery with aerosol spray paint requires proper preparation, the right products, and a methodical application to achieve a durable and professional finish. Here's a step-by-step guide

  • CLEANING

    Clean the Surface
    using a degreaser or industrial detergent.
    Pressure wash large machinery if necessary.
    Allow surfaces to dry thoroughly.


  • RUST REMOVAL

    Use a wire brush, abrasive pads, or a power tool (e.g., grinder) to eliminate rust.
    For pitted or flaky areas, consider applying a rust converter before priming.

  • SANDING

    Lightly sand glossy or previously painted surfaces with 240–320 grit sandpaper to improve paint adhesion.
    Wipe clean with a tack cloth or lint-free cloth dampened.

  • PRIMING

    Use a primer formulated for metal (e.g., zinc phosphate or etch primer).
    Apply 1–2 light coats of aerosol primer, holding the can 20–30 cm from the surface.
    Allow full drying time between coats as per product instructions.

  • SPRAY PAINTING

    Shake the can for 2–3 minutes to fully mix the pigment.
    Test spray on cardboard before applying to machinery.
    Maintain a consistent distance of 20–30 cm from the surface.
    Use a crosshatch pattern (horizontal then vertical) for even coverage.
    Apply multiple light coats rather than one heavy coat to avoid drips. Allow each coat to dry 10–20 minutes (or as specified).

  • (Optional) Lacquered Top Coat

    For added durability, apply a clear lacquer spray after the colour coat has fully dried. This improves:
    Gloss and finish
    UV and corrosion resistance
