Answers:
What are you painting over? Over previous paint or wallpaper?
If you're painting on straight plaster, did you seal the plaster first with a 50/50 mix of pva glue and water?
Sounds like there could be either something on the walls thats affecting the paint or the paint might not be miexed properly.
Paint pads are great, they tend to "streak" on the first coat on dirty paint, but the second coat should go on fine.
Are the dark spots stains?
Sounds like you need a primer coat.
binz 123, or KILLZ will cover anything, and your finish coat will look much better.
If you had dark spots on the first coat, I have to assume that you did not use a primer/sealer on the walls. Could be the previous color or grease/oil spots coming through.
Budget and cheap paints are thinner than brand and quality paints.
You should always give a wall a quick sand to give the surface "key" and paint it with a roller of budget paint to start the job off with then slap a coat of quality finish on top, it makes for a smoother even finish and helps mask colour changes.
The number of coats is determined in the colour change, if its allot of difference then you will need to apply more coats to neutralize the base coat below the cover up job your doing.
I've never had bad paint do this; only if there was a stain previously on the wall. Fixing it would now be a big pain! You'll have to prime or kilz the area again and repaint.
try a paint brush it uses more paint if that dont work its back to recoat with a different colour (white) and repaint
You should always wait for the paint to dry properly, before giving the walls a second coat. you should wait at least 24 hours to see whether those spots were not just wet paint. Next time try to use a roller instead of those paint pads which are useless on big areas.
what did you paint over if paper it may dry out if walls then try a better paint or paint patches with pva and then re paint all paint looks patchy till its dry.
All of the above is correct but I want to say one thing in additon to all of that. If you did plaster this wall before painting you really have to allow the plaster to dry. I already had it where it really took a few days for the plaster to totally dry. If it is not dry and you paint over it you will get the dark blotches showing up. It will then take that much longer for the plaster to dry since the moisture now has to be transferred to the paint above and evaporate from that level - this could take a week I would think. More coats means more time but the moisture blotches will vanish once it is all dry if this is the cause, as stated early on.
