Paint the steel staircase yourself or leave it to the painter?

Yes, that's exactly how it was installed with us. But it is supposedly not a "real" primer. Of course, I don't really know much about it.

Our paint still adheres excellently - we were told that this is the primer, rust protection

Which is also sensible, since the stairs are usually installed while the construction is still in full swing and there is still a lot of moisture around. I am way too picky to do something like that myself. :D

Please do yourself a favor and use a paint roller and not a round brush. Then I'll smirk back @ypg

Says the one who first…

but scraping, sanding, priming and only then painting.

writes that… on a primed staircase! Well… :cool:

I recommend Grönemeyer with
"Alcohol is your paramedic in emergency
(Alcohol) is your parachute and your lifeboat"

Instead of sanding the primer, cleaning (dust removal) with isopropanol is sufficient. Please do not drink. ;)

Thank you for the many tips and suggestions

That's also ahead of me. I specifically stocked up on Bosch Blue. Please don't tell my wife that it was unnecessary....

Does anyone actually have before-and-after pictures, possibly with work in progress?
