I have a brown stain (no jokes please) in the corner of my ceiling that
won't cover up no matter how many coats of emulsion I give it.
The ceiling is of lathe and plaster construction and is painted in Dulux
white emulsion. I think the original stain was caused by a leak from the
bath waste a couple of years ago that has long since been cured and fully
Is there a product on the market that I can use to seal the ceiling to stop
this stain coming back?
Thanks for any advice,
try painting a light coloured oil based paint such as undercoat over the
stain, allow to dry then paint over normally with emulsion. If that doesnt
work you can always use an aluminium sealer/primer but you may need 5-6
coats of emulsion over the aluminium to cover that. The aluminium sealer is
used after a fire where oily smoke has got into the plaster. It seals
everything but needs a bit of drying time plus several coats to cover
especially a light coloured emuldion. The silver seems to show through even
when covered with 2-3 coats emulsion
I've used (sucessfully) Polycell Stain Stop -
I've also used, with less success, white oil based undercoat.
I've got a similar problem to yours in one of our bedrooms which will be
painted over Christmas. I'm going to try Screwfix's Stain Block - item
code 15679. Anyone tried this?
I've always found that stains can be stopped coming through emulsion using
any old bit of gloss (or even varnish) that you have left over. Brush on a
generous coat and when dry overpaint with the emulsion - save your money and
don't buy a specialist product (unless the stain is something very odd!)
Did anybody mention varnish?
We had grease stains on a ceiling from something weird somebody had done
to the roof or in the loft, and a local builder suggested painting over
them with varnish before emulsioning. Worked like a charm.
I went on a course.

Interesting. I've always believed that painting on top of gloss was a
no-no, unless you prepared the surface first by rubbing to provide a
key for other paint to cling to.
Maybe my information is out of date though.
