(Concrete) ceiling painting - is pretreatment necessary?

Did you use silicate or regular paint? And which MIPA shop were you at?


Cleaning the ceiling is just a huge mess, it usually costs a bit more per m2.

No idea, the master painter took care of everything, I didn’t have to worry about anything except completing my basic work on time. Everything was from MIPA, including the primer.

An acquaintance told us that it is quite enough to just fill the joints and then simply paint... Is that an option? Has anyone tried that themselves before?

Yes, with us.
However, our bricklayer filled the joints. He did that very well.
We primed and painted. Not Alpina, but with painter's paint from the wholesale store for painters, so a specialist dealer.
Painted twice, looked very blotchy under spotlight. In real life, you don't see anything - we did a good job.

It is important, if it is silicate paint, to paint wet-on-wet. That means, not painting the corners first but everything as quickly and over large areas as possible. Additionally, a thinner that extends the processing time does no harm.

So, I have now cleaned the joints and applied primer. I have test-filled two small joints with the Rotband filler. Let's see how it looks tomorrow.

Do you actually have to brush the entire ceiling with primer? And if you fill the whole ceiling, do you only scrape it off? So that only all the small holes are closed?

How did it end up for you in the end? Painting the concrete ceiling is now on my agenda too
