Can I use exterior paint on ceiling?

Hi,
Just curious, the tin of paint I have says external use. This paint looks and feels pretty good and I was thinking about painting the internal ceiling with it, what is the harm.
Paint is Sandtex exterior, extra smooth.

You can I suppoose but its an awfulkly expensive way of painting a ceiling. Hoiw old is it? If more than 12 months old then the best advice is to ditch it TBH.

I can't see that paint being fine enough for a good finished result on a ceiling and I wouldn't be sure of a reaction with other paints in the future. I wouldn't.

The Paint is brand new tin, have bought these to do the exterior of the house. When I took the paper off, the ceiling had water damage hence this bright idea to cover up the stains.

You can use Stain Block paint first of all. Cheapest I've found is under £4 here http://www.amazon.co.uk/Everbuild-EverBuild-Stain-Block-400ml/dp/B00578300M/ref=sr_1_4?ie=UTF8&qid=1350316494&sr=8-4

I'm not sure if your masonry paint would do the job anyway.

Fineness may not really come into it . It depends what finish OP wants. Textured paint is hardly fine.

As your exterior paint is waterbased the stains will leech through. Cheapest solution is a coat of spirit based (not water based) undercoat over the stains first. Stain block will accomplish the same result but at a greater cost.

I remember in one of the TV program, one of the ceilings had water marks the builder used some old tin of gloss paint , to cover the stain and then painted over with emulsion,
I think i will go with the recommendations and not use the exterior paint.

I wouldn't use gloss paint. You'll never match the texture when you overpaint.

Get some proper stain blocker and cover the stains first. It doesn't cost much and it will do the job properly.
