Rated 4 out of 5Â by LeDoc Stain block
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.

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

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.

Rated 4 out of 5Â by JohnyF Worked Reasonably well
Used this produce to cover nicotine stains on a buy to let we had just bought. Covered 90% of the stains in one coat. (10% of the ceiling showed slight yellow when coated with emulsion). We then re-coated the 10% with stain block and after another coat of emulsion it was all white. Also tried a more expensive branded product on a different ceiling and got a similar performance. I have little experience of stain blocks but I think that it is pretty difficult to keep the stain away which is why this product gets poorer reviews. I have used the aerosols in the past on small stains and found them very successful but would have cost a fortune to do all these ceilings with that product. If it is a small stain I would recommend the aerosol as an alternative however. You can apply more coats quickly with it. on a small area.
