Recommend a stainblocker

The previous owner of my house had paneled a bedroom. It looked bad, so I took it down. I discovered the paneling was held to the drywall with some small nails and allot of panel adhesive. The adhesive they used was not like liquid nails, it is an older type probably from the 70's. It was black in color. and was very brittle. After scrapping it down to the drywall, I painted over it, and about a year later, it bled through the paint.

So I put on some Kilz stain blocker, but it is visible again Now about two years after applying the Kilz.

I don't remember what kind of Kilz I used, (oil or latex) I know the wall was painted with latex. I had heard you can put latex over oil but not oil over latex. I have latex on the wall now but I don't know what is the best stain blocker to get. Or whether to use latex or oil.

Can someone educate me on this ?

Thanks Mike

Not at all true.

Oil base stain blockers are better than latex although they smell more.

Even better than oil base stain blocker is pigmented shellac, such as B.I.N. It smells too, but some people think it is a "good" smell.

Although it usually is not promoted as such, oil base aluminum paint is the absolute best stain blocker. It's rarely used because it is so sloppy.

Latex Kilz is a good primer and blocker but you probably just needed

2-3 coats to block that stuff. Similarly, if you've ever gotten trim stain on drywall you will know that it takes several coats of primer to hide the trim stain. (why it's always best/easiest to stain your trim Before cutting and putting it up). This glue is probably a similar situation and it's a dark color. Latex over oil always needs a primer to bond the two types, oil over latex less-so but still not a bad idea.
