Start off by using a dark undercoat, before going in with your top colour. It makes the best base for the dark colour, particularly if your current wall colour is light. You could choose a specially-made dark tones undercoat, or just a dark toned paint from a cheaper brand.
The primer coat doesn't have to be perfect, but it should cover the surface (no bare spots) and it shouldn't be so blotchy that you get drips or visible unevenness. Niall C. Niall C. I find this to be true with every step of the wall finishing process.
Next is the undercoat (unless you are using a multi-purpose primer and undercoat): again, one coat may suffice or two might be needed to cover dark colours. Now for the topcoat – the colour you want the walls to be. Two top coats is the norm, but sometimes extra coats are necessary to get the required evenness.
For most colors, tinting the primer to a slightly lighter shade than the finish coat provides a better chance of reaching full coverage, and it helps you see where you've already painted your finish coat and where you still need to paint.
"Think of the color wheel: Colors that are opposite from one another will help cancel the other out," says makeup artist Molly R. Stern. For example, if you're battling redness, go for a green primer. A purple one gives sallow (yellow) tones the knockout.

Personally I would buy a white undercoat and a smaller tin of the dark grey, and mix my own light grey undercoat. The main thing is that you give any old paint work a good sanding before applying any aqua products.
In most situations, a good rule of thumb is to use a primer plus two coats of paint. If you use this rule, you may do one more coat than needed but this won't hurt the final product. There are few situations where this rule of thumb will result in doing too few coats though which is why it is prevalent advice.
Adding a Second Coat
A good rule of thumb is to wait at least three hours to recoat your paint or primer if it's water-based. Waiting 24 hours is best for oil-based paint and primer. If you're unsure, the instructions on the paint's label can give you the best final say.
Use the same technique for applying the undercoat as you used with the primer. Once dry, give the undercoat a rub down with the 220 grade sandpaper before cleaning with the rag again. If you want a nice smooth finish then sand between each coat of paint.
Yes you can but.... If it's peeling it will continue to peel. Lacquer thinner, lots of rags and good ventilation will get it off. When you do undercoat toss a little bit of urethane hardener into the mix.

Undercoats and priming
If you are covering a dark colour or a surface that's never been primed or painted, you will need to use an undercoat. It can also provide a better coverage and hiding power than just applying extra top coats.

Throwing dark gray primer underneath your navys, grays, and blacks will drop your color shade so you won't have to make such a drastic jump when you start painting.
Apply one or two layers of undercoat depending on what the instructions say and how porous the wood is. Some undercoats are very dark, handy if your topcoat will also be a deep colour. A deep grey undercoat, for example, is perfect if you want to paint the wood in dark green, deep burgundy or black.
