No Nonsense Stain Block White 750ml
Does not block soot stains
A broken chimney stack led to some sooty water penetrating the wall in my kitchen. After cleaning and allowing the area to dry thoroughly (two months) was concerned by a few small stained areas so used this paint prior to top coat.
Four coats later the brown stain is still coming through. As I don't want to top coat in brown I need to find another fix. I think the problem is that this paint is water-based.
I wish I had read all the feedback rather than the first page!

Had a stubborn stain left on a ceiling which has repeatedly returned from old soot staining where chimney was removed years ago. Two coats seems to have done the trick, I'm impressed as I've used other "named" sealers before and it's still leached through.

THE TIN LIES!
Poor opacity. Stains bleed through far too easily. Three or four coats required. Nothing like as good a conventional primer or undercoat.

Doesn't do what it says
Got a tin of this to cover some marker pen marks and a dried water mark - after 4 coats of using this the marks were still coming through. Went to a local cheapy shop known for its good discounts, who had a brand named Stain Block for the same price - did the job in one coat. You could tell the difference immediately with the consistency of the paint itself.
