Dulux matt wall paint not taking around the edges?

[acknowledged74]

Hi

Hopefully someone can help.

Please see pictures.

I am painting over a wall papered wall that had been painted some time ago. Most of it has taken just fine, but patches took the first coat but wont take another, and the edges that I'm trying to do with a brush will take a thick bottom coat but nothing else. Very strange, any ideas?

I was thinking maybe I could sugar soap those areas (though its a few large rooms) though this will be a right pain.

maybe sanding the first coat in these places so that the next coat will take?

Please Help.

Additional. I can see that quite a few people have looked, but I've had no responses. Maybe you think its a silly question, not to me.

It's possible there is PVA on the wall, as a rule it's like painting teflon, but as the first coat takes it's a bit strange, perhaps your first coat has activated some old PVA that has mixed with the paint.

You could try using a coat of oil based primer on a small area to test, or better still Zinsser Bullseye 123 which will take on difficult surfaces.

Basically when I try to roller or brush in these areas I just doesn't take, you can see its not sitting correctly, like oil and water I guess. But as mentioned is has taken an undercoat everywhere, and second and third coat in 90% of the 4 rooms and hall way.

I have tried Ronseal Flexible Basecoat White 2.5L, which is meant to prime and deal with strong colours, this seems to have taken even worse than the normal emulsion?

Arrrrggggghhh just doesn't look great not sure what to do here. If I use an oil based primer wont it look completely different when I come to 2nd coat it?

Safest bet is the zinsser, yes any white primer you put on will need an extra coat of colour but only a brushfull over the white, then continue as before.

The cheapest price for litre will be about £14 from a trade supplier.

I always use the Zinsser product but lots of people who prefer to hang onto their pennies say they use ordinary primer and get good results.
