Wooden ceiling painting (airless) - Color recommendation?

Hi. I would like to paint or spray our 200m2 wooden ceilings and beams white. These are profile boards and KVH beams. The profile boards are wood-colored and the beams dark brown. Of course, I am currently sanding everything thoroughly. Now I am looking for a good white paint that ideally primes, seals, and covers. And that can be applied with an airless device (Wagner 250M). I have already tested Jansen HDF Pro (with brush and roller). But the paint only covers moderately and is very thick. Does anyone have a recommendation for a suitable paint? Ideally solvent-free, but that is not a strict requirement. Thank you very much. Greetings from Cologne

It should be forbidden to paint a beautiful wooden ceiling white. I have had good experiences with Bondex stains, which have been around forever. If necessary, just apply two coats.

Take a look at Osmo, I've used them many times. I remember that we applied decorative wax directly and without sanding (just cleaning) in a fully covering manner on a wooden floor, it worked wonderfully and still held up perfectly after 10 years. I believe they also have sprayable paints, you should inquire about that. I can't quite imagine how it looks afterwards with white paint because you can see every dark spot (knots, etc.), and there will be many of those. Sanding 200sqm of profile wood on the ceiling is a job, oh dear, and then spraying indoors...... Do you have experience with that? To me, it sounds more like I would screw something new on top or replace the old if there really is a necessity. Do you have any pictures?
