Bleeding through BIN, now what?
 
We have been told we have "bleed thru of old nails (possibly as a result of a formerly leaky roof)". We replaced the roof.

Now were are repainting the ceilings and have applied "BIN" (on the advice of this forum's multiple posts and our paintshop) over the spots where we have these yellowish-brownish bleed thru spots. But we can still see the spots thru the BIN.

The paint store told us that "it's OK. Just paint over the BIN. The spots should not show thru the paint now." Are they correct? ...or do we need to use another/different "stain blocker" primer for such stubborn stains?

You should be ok to just paint over the bin as long as you got a good adhesive with the bin. Primers like bin are not made to cover the problem area by themselfs, they are made to seal the problem so that bleed through does not occure.
It should be fine as long as you did not thin the product to the point of making it uneffective. You could always put another coat of bin, yet usually that is not needed

BIN is the ultimate weapon against bleed through
There's none better

The area may not look "pure white" when sealed, however

Some of the stain may be showing through visibly
It should be sealed out with the BIN though (if applied properly)
And not visible after painting

Sometimes when you apply white primer (one coat) over yellowish/brownish stain, no mater what you use , BIN,SW,BM..., you may still see
through the stain.

If it is a see through, i don't think you need to prime again. Apply two finishing coats, and that should take care of your problem.

Think of BIN (or other stain-sealing primers) as saran-wrap for your stains. While they won't hide the stain, they keep it from coming through to whatever you put on top.

I wanted to get back to all of you on your advice and thank you. The BIN "wrapped" the stains, letting us paint over them with ZERO bleed thru. We were happily impressed.
