I've just repainted a bedroom ceiling that had been stained by a leak
some years ago. The repaint seemed, initially, to have been successful
but now it's dried the stain has reappeared.

Any suggestions on how to stop it reappearing after another repaint?

Dilute PVA?

TIA

Use stainblock paint over the stained bit before you paint the ceiling
(oh, sorry!) - works very well.

Dulux/Polycell Stain Stop.

Gloss undercoat, then repaint. Used that a number of times and works fine.
Tip provided by our local painter.

Why would a glue stop a stain? You need something that isn't water based.

Any oil based paint will do, though something dark to be covered with
white emulsion isn't a good idea. You can get proprietary stain blockers
but they are expensive compared to the left over can of white gloss on
shelf...

Check out zinsser stain blockers. you can get them from the larger B&Q
stores. The aerosol versions are particularly convenient.

I used Ronseal "Quick Drying" Stain Block for exactly the same type of
leak (from a tank I had in the loft many years ago). I used a couple
of coats of the spray, then painted over with Dulux brilliant white
rich matt.
The Ronseal stuff can be overcoated after 10 minutes.

That is about the only advantage of the proprietary stuff has over the
left over oil paint route.

Because PVA forms a 'skin'?

The white gloss sounds good so long as it won't alter the texture of the
silk emulsion used to overpaint it...

But a water permiable skin.

I haven't noticed any effect on the overcoating texture.
