Im sh1te at DIY, and hate doing it but needs must.....
Got to paint some walls with emulsion. Some areas of paint flaking off,so if I just paint over the top the flaking will still be visible.
How to prevent this ? Sandpaper the edges of the areas concerned before painting ? Or is there some trade secret which does it better/easier ?

just small flakes? I'd sand it off so its smooth, wash down walls then paint.

If its small chunks of flakes, I'd mix up some poly filler, fill it in, let it dry, sand smooth & paint

quite large areas flaking.Its not plaster just paint flaking.Dont fancy sanding it all level & smooth,but if thats the only way to do it then so be it.

Aside from the new paint falling straight off again, it will also be more prominent than the proverbial "spare part at a whores wedding" when the paint dries.

I'd personally hit it with a bit of 80 grit (or thereabouts) paper to remove the flaky paint and then lay a thin skim of "Easyfill" type polyfilla and rub flat when dry.

Two answers saying much the same thing.That looks like a decision then.Visit to DIY shop tomorrow unfortunately.
Got loads of wet& dry,but no sandpaper.Plenty of bodyfiller but no pollyfilla.

After you've finished you'll probably appreciate just how reasonably priced a painter & decorator can be!

I had a constant battle with a wall that kept flaking paint off at the last house. I don't know what paint had been used underneath but it was flaking off in some places and stuck like the proverbial to a blanket in others. I would bite the bullet and take the wall down to plaster. That way you know you're only doing it once.

A trick I learnt was to rub it down then mix a very small amount of filler powder with some old matt white imulsion then roller it on. Leave it to dry out for a couple of days then give it a light rub down 
Works a treat

agreed.. although fillers can be used, wont  stay long and you have to do it again.. check if there is a water pipe beneath it.. a similiar situation I had with the neighbour and it required to repair their leaking bath pipes

Nothing wrong with using bodyfiller on your walls, have done it many times. I go round hook off all the loose stuff, mix up filler and apply. 15 minutes later and I am ready to rub down. I can't be bothered waiting for poxy polyfilla to go off.

I also use a half sheet sander all over the walls, they cost a lot more but are well worth the extra. Third sheet sanders are not worth buying.

Just my useless 2p worth

Nah, you could empty your bank account and 2-Pack Epoxy paint it!  As long as the wall is dry and oil free it sticks like man-juice on an Essex girl

I think the problem I had is that the original paint, in addition to flaking in some areas, was incompatible with the emulsion I was trying to cover it with. So, you'd sand off all the loose stuff, paint over the paint that's firmly stuck, stop for a cup of tea and then find that stuff had started bubbling off underneath the new paint.
