Because it will avoid problems with
- old oil-based paint (you ABSOLUTELY need a primer over an oil-based paint before painting with water-based/acrylic pain)
- patches made of different material (patches of plaster for example) that would react differently from other parts of the wall
- bare surfaces (new walls) which won't give good adherence
- colour changes (if painting over walls of different colours, the result will look different with the first layer(s) of paint. The primer can help)

If it's alkali then you'd have to use a neutralizer, like water, ammonia or baking soda, prior to painting. The pH of the surface has to be below 10 prior to painting.
How do you prepare a latex base paint to be covered by oil base polyurethane?
You'll want to ensure that the surface you are coating is clean, dry and relatively gloss free prior to covering with any coating. A primer is normally not needed in this application however a common saying in painting is "never say 'no' to a primer." In this case, it would add an extra layer of protection along with insurance against peeling.
Before I paint a cork bulletin board it is recommended that I use a base of Shellac first before I spray paint so to eliminate bleeding through can i use clear enamel spray if i do not have shellac?
A clear enamel spray will just absorb into the cork. You might as well use the paint straight. Get a stain kill primer or a shellac based primer ant coat the cork prior to painting.
Can you paint red over grey walls?
Yes. Normally, you'd want to put a grey primer on prior to painting a wall red because most reds cover poorly, but the grey will keep light from reflecting back through the red paint, giving the illusion of good coverage. Be sure to apply the paint evenly and always work to a wet edge to avoid lap marks which would require applying another coat.

Can you paint over preserva wood?
Yes you can. There are many types of wood preservative but once they are thoroughly dry, the wood can be painted. You should read the instructions on the label of the preservative to see if there is any specific reference or recommendations in this regard. If not, I would recommend an oil based primer prior to painting. An oil based primer will help ensure a good bond and isolate the finish paint from the chemicals in the preservative which might leach into the finish coat and discolor it or chemically degrade it. Water based primers are probably ok too, but , you should look for a claim of stain sealing ability on the primer label if using a water based primer.
