I want to repaint a latex paint applied to the ceiling about 55 years ago with latex paint again.
My local painter suggested applying a primer first, then a coat of latex paint, which should be sufficient since the original paint layer is still in good condition.
I already bought the latex paint myself, of course from an expensive but competent specialist retailer nearby, because they offer the best materials and advice.
Unfortunately, the specialist retailer disagrees with my painter, and I have received two different answers over the phone from the retailer (thanks to the pandemic):
1. No primer should be used; instead, apply two coats of latex paint. The first coat will smear, but the second coat will make the ceiling look good.
2. A single coat of latex paint without primer is enough.
I’m quite uncertain, especially since online DIY guides recommend “degreasing with alcohol, roughening by sanding, and, like my painter, consider primer necessary.” My painter, on the other hand, thinks degreasing and sanding are unnecessary.
How can I apply the new latex paint permanently over the old one?

Why are you questioning the expert’s professional opinion?
Just let him handle it.The trained painter is nice and young.I have known the specialist dealer for decades, and he says to simply apply latex paint over it, possibly twice, to make it look better.

Priming costs nothing and is quick to do. If it is missing but needed, it can cause major problems.
I think priming makes sense here to ensure the surface is not crumbly. An old paint layer that is 55 years old is quite significant.
Whether a second coat is necessary can be decided after the first one.

Great view Well, I was young once too, but experience is hard to replace.
It turns out that the ceiling coating, initially identified by the painter as latex paint, is actually glue-based paint. The latex failed the wipe test with a damp sponge 🙄
Now 70 m² (750 sq ft) of glue-based paint must be scraped off the ceiling 🙁
Even the painter found it too tedious to use the long-handled sander (“the giraffe”), so the ceiling was moistened and scraped off with a putty knife 😡
If anyone knows an easier method, please speak up now...
