Hello everyone,
We've just moved into a rented flat that has what looks like very ye olde woodchip wallpaper all over the walls. To make matters worse, it looks like it's been painted over and over again with cheap shiny vinyl silk paint over the years! 
The landlord painted it a really yucky, greasy-looking magnolia just before we moved in. It was a really bad paint job though - it's got bubbles and cracks, and it peels in places.
We're allowed to paint it white thank goodness, and I'd love to give it a matt finish. The shiny vinyl silk stuff only draws attention to the woodchip's lumps and bumps!
The property doesn't have rising/penetrating damp but it's prone to condensation (despite us constantly ventilating and running a dehumidifier).
From what I've read it's not possible to do a coat of matt emulsion on top of this. I was wondering if anyone has any advice for how best to tackle this to give it a less-shiny, plain white finish?
Thank you very much in advance
