Paint on cracked walls - recommendations needed

[Absa]

We have a room where really all the walls need re-plastering as the plaster is shot and there are hairline cracks everywhere. However, for now we want to just make do with it as will also be replacing the floor in the next year so will do it all properly then.

Can anyone recommend a good paint (in the UK) that covers hairline cracks effectively?

Paint won't really do it, at least not without trowelling it on at great expense. I'd stick to polyfilla and a rubdown with fine sandpaper, then your usual tub of emulsion.

I know Polyfilla used to make an undercoat designed to cover hairline cracks. It's basically paint and filler blended together.

Thanks @CockCarousel I'll have a look

Have a look at Polycell 3 in 1 Basecoat.

They say...

• A unique undercoat for walls and ceilings that completely covers all common wall imperfections
• Permanently covers cracks, stains and strong colours in just one coat
• Easily applied with a roller, straight

I've used the polyfilla under coat and it is good it's worth a try x

It's tricky to find (last got some on eBay) but polycell make a brush on hairline crack filler which is fantastic, hardly need to sand and no messing about with trowels and filler, painted a very cracked room straight over it and still good a few years on!
