Painting over bitumen

[MrBoater2021]

I’ve currently painted 2 coats of blacking on the hull and a third is going on after 24 hours. 
I want to paint over a section with red oxide for boat viability. Is it ok to use red oxide over blacking paint?

What does boat viability mean exactly in this context?

Mean’s when I’m pissed I know where to step. 
 

opps. Visibility.

It would be a waste of time. The red oxide will colour the blacking, and probably turn a brown colour, as it mixes with the bitumen. The red oxide won't be doing anything.

If you paint the gunwales and deck a lighter colour deck paint you'll have better visibility and know where to step. Red oxide on the [outside of the] hull if that's what you meant isn't going to help in that respect as that's not where you're stepping?

 

I hope you haven't painted bitumen on the gunwales and decks? That's a horrible idea.

Ah, Visibility.  Oil based paint will not do much over bitumen.  White sticky tape may be better.  Or reflective red tape like bike reflectors?

Good idea.

Aluminium paint painted over the bitumen blacking first will seal it and then paint over it with red oxide or any oil paint.

Yes if you want a silver paint that will stick to bitumen try International Primocon primer or Jotun Vinyguard - both basically the same.

 

Not that you want to be stepping on those paints as they'll be slippery when wet, as will bitumen.
