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.

It depends. If you are painting over a deeper color or a really bright one you will get much better coverage in fewer coats with you new paint if you primer first.

Priming the wall is just to seal it so the paint doesn't soak in and dries more evenly. You may have to put two coats of paint on depending on the quality of the paint you are using.

How do I get rid of a bees nest in my porch ceiling HELP?

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.

Yes, even weatherproof paint will need a top coat. Creating a top coat makes a great seal to keep the paint in, which prevents it from being damaged.
