Ceiling painting - can't cover brush marks

[Kes]

We have had a large landing ceiling replastered (end 2009). Last week I gave it a prime coat of thinned Dulux Vinyl Silk emulsion from a spare tin. I then gave it two coats of B&Q Colours matt emulsion (Antique White). To my disappointment it still looked patchy. I'm starting on a third coat and I can still see brush marks in the finish.

Now it's a pain to do the ceiling, what with my poor neck and struggling over the stairwell. It's also just about impossible to see where I'm putting the new coat on top of the old one. I am applying by brush, by the way, the paint seemed to heavy for a roller. Is there anything I can do to get a non-patchy cover without brushmarks? I have done other ceilings before, I think with vinyl matt, and they cover wiith two coats and have no brushmarks. I know the paint is B&Q but it wasn't particularly cheap. Should I go for say a Dulux vinyl matt (the B&Q is just matt, no vinyl)? Is it that the paint is just matt? (Incidentally the Dulux website seems to have removed the word 'Vinyl'.)

Any speedy advice would be greatly appreciated.

That is so wrong, I`m afraid. Should have been a non- vinyl ( Trade ) matt . Could be why you`re getting brush marks - Seriously, I would bite the bullet and go over it with some water based Zinsser. from a trade shop- ask the staff what they think Because it`s not cheap , but it is a problem solving coating.

brush marks?

use a furry roller

If the paint seems a little heavy for the roller, then just thin it down a little with water. Best use a roller to cover the broad area and cut in with a brush after. Because you have used a silk as a primer the other coats are probably skidding around on it. As Nigef says always use a matt or trade matt, thinned down as a primer coat and then fuller top coats to follow.
