The bottom line is that watery paint is unusable. So if your paint is too watery and you attempt to use it to paint your home, you will notice that the paint won't adhere to surface correctly. It will be 'thin' and therefore will perform poorer than expected.
You might notice the consistency of your paint has changed. There may be a “skin” on the surface or lumps that won't stir out. If either of these is present, your paint has most likely expired.
When you thin too far, the solvent side of the ratio goes way high and you lose both control of the paint (it runs everywhere when you put it down instead of laying where you place it) as well as pigment coverage (more solvent means less of the ratio is pigment.)

When a painting contractor waters down paint, they are typically adding a significant amount of water to it. Think two gallons of water for every five gallons of paint. In contrast, the process of thinning paint involves a relatively small amount of water: 2-4 cups for every five gallons of paint.
A too-watered-down mist coat, however, will evaporate before soaking into plaster and won't provide a bond.
Adding a few drops of warm water is a quick fix for dry paints.
Aside from consistency or texture, another way to know if the paint's gone bad is just to smell it! If it smells unpleasant or you see mold, you will need to discard it (correctly). And, yes, mold can grow inside a paint can and be a serious health hazard if you put it up on your walls.
For one, the expired paint will have adhesion issues. More importantly, it can be hazardous by giving off excess VOCs or paint fumes. In this case, it's best to get new paint. However, the paint may still be good if the water has separated from the solids.
Impacts on Texture and Finish
If the paint is too thick straight out of the can, it may need to be thinned using the appropriate thinner (water for latex paint, mineral spirits for oil-based paint, etc.) to reach the right consistency.
Avoiding excess clearcoat
Some parts are particularly sensitive to excess product, such as vertical parts (flaps, doors, etc.), which may result in possible paint defects, such as sagging clearcoat.
The new plaster will be very absorbent and will suck the paint into the surface. Thinning the first coat with 10% clean water will help but the second coat will go much further.
All you need to do is dilute some emulsion paint with water and apply it to the plaster using a roller, paintbrush or spraying. One mist coat should suffice, but you can apply a second (or even third) coat just for extra peace of mind.
