Why is the paint still scratching off my primed, spray-painted tin?

Answered

I primed a clean floor polish tin can with two coats of appropriate spray primer then sprayed it with colour. The first time I put something in it, it scratched. Why is the DIY world conspiring against me?! These tin can crafts are all a lie!😫

    Hi ! Did you scuff the surface with sand paper first ? And more importantly , did you put on a clear coat or two , to protect your work ?

    I don’t know what a Floor Polish Tin Can is. Is this a steel can that had floor polish in it?


    What I call a tin can is actually a coated steel can. The coating is often a plastic-based High-Temp coating, so that the contents don’t rust the steel.

    Galvanizing is another coating (zinc) that needs special “treatment”.


    I would both chemically & physically abraid the coating. I would use fine sand paper & thoroughly sand off what’s there, wipe down with vinegar, let dry and sand it again with clean sand paper. Vinegar wipe & then vinegar soak for 20 minutes. Then dry thoroughly.


    Then re-Prime & re-paint.

      This kind of floor polish is sold also in some parts of Canada.

    You need to ruff up the surface so the paint sticks

    Yes, fine sand paper & wipe clean with vinegar.
