Shower – Repainting damaged acrylic coating on the shower tray. Help!

bathtubpaintingshower

I was cleaning something in the shower tray and I used a chemical which was petroleum based (which I didnt know), which caused the acrylic coating (I think its acrylic coating) dissolve.

I did a bit of research about repairing bathtubs/shower trays and it seems like nobody is able to achieve quality results by painting it, this usually involves using some kind of epoxy mixture, which cures for a very long time.

However, I have a different idea which nobody seems to be trying out…
What I want to do is:

  1. Use coarse sandpaper to the damaged area
  2. Apply filler (what filer?) to level the work area
  3. Use sandpaper again (medium)
  4. Paint white (spray)
  5. Apply acrylic clear coats (spray)
  6. wet sandpaper medium>fine>extra fine
  7. Buff it with a cutting compound to get the gloss on

Questions:

Is there any problems with my approach (if any)?

Is there a better way of doing it?

  • Use coarse sandpaper to prepare the damaged area- GOOD

  • Apply epoxy repair filler to level the work area- GOOD

  • Use sandpaper again (medium)- GOOD

  • Paint white (spray)- NO

  • Apply acrylic clear coats (spray)- NO

  • wet sandpaper medium>fine>extra fine- GOOD

  • Buff it with a cutting compound to get the gloss on- NO

Rather than using spray paint, use a 2-part brush-on epoxy paint specifically designed for wet service, such as this. Repaint the whole shower pan. Note that this is fine for acrylic, but not for flexible plastic shower bases. This kind of coating can be made non-slip by adding an aggregate additive and can be tinted almost any color. And it is exremely tough/durable.
