It all depends on the ceiling. If it is newly installed sheetrock than it must be primed prior to painting. You should also prime before painting over any discolored or an extremely dark colored ceiling especially if you plan on painting a light or neutral color.
Primer is needed when there is no existing paint is present. If new drywall
is present then a drywall primer is applied, a paint primer then paint.
Read the instructions on what ever paint you buy. Most new paints say that you don't need to prime over the old paint and they cover better then they use to.
So you follow the instructions on the new paint, it will either recommend priming the walls or it won't. But if you don't use a primer over old paint, you should buy a paint cleaner
that preps the wall for the new paint. This will give the old paint a good surface so the new paint adheres well to it and down the road you don't get bubbling or peeling.
If the ceiling is newly installed, has recently been repaired, is water stained, is a "textured" ceiling or a colour that will require several coats to cover, the answer is YES. In the case of water stain be sure to use a shellac based primer such as Kilz (Kilz2 is not as good).
If you are painting over a flat, white (or pale coloured), old surface that just needs a "brightening up" then NO.
Yes, otherwise you will seal in moisture causing potential rot and mildew.
I believe that you prime than paint than seal. It depends on the paint you are using and what you are painting A lot of the exterior paints used today don't require any undercoat. However if you are painting over a previously painted surface you must keep preparation in mind.
Open celled foam must be sealed prior to painting. The seal is a simple mixture of white glue thinned with water and brushed on.
On the ceiling of the Oval Office is a painted Presidential Seal. Over the fireplace hangs a porthole portrait of the first US President George Washington by Rembrandt Peale painted in 1776.
No, you need to remove the tacky coating before anything will stick properly.
Yes, otherwise you will seal in moisture causing potential rot and mildew.
Yes
No, painting over mold with Kilz may temporarily cover it up, but it will not effectively seal or remove the mold. It is important to properly clean and treat the mold before painting to prevent it from coming back.

To achieve a straight line when painting between the wall and ceiling, use painter's tape to create a clean edge. Apply the tape along the edge where you want the line to be, pressing it firmly to ensure a tight seal. Paint along the edge of the tape, then remove it while the paint is still wet for a crisp, straight line.
Well, on the ceiling there is the Presidential seal.
No. You seal the top part of travertine AFTER it's installed.
To seal cardboard for painting effectively, use a primer or gesso to create a smooth surface that will prevent the paint from soaking into the cardboard. Apply the primer in thin, even layers and allow it to dry completely before painting. This will help the paint adhere better and create a more vibrant and long-lasting finish.
You need to be sure of what it is before you decide upon removal tactics. Is it a bee hive that is actually in the ceiling or wall, or is it a wasp or hornet nest that is visible and stuck to the ceiling or wall? If it is a bee hive there will be honeycomb involved and that will all need to be removed from the ceiling. Call a professional to smoke out the bees, open up the ceiling, remove the hive, and then seal the hole. If it is just the papery nest of a wasp or a hornet or the mud nest of a mud dauber, those are easy, get some wasp and hornet freeze. soak the nest and let it soak about 24 hours, then knock the nest down. Make sure before you knock it down you don't notice any activity.

We used paraffin wax to seal the wood before painting it.
