I understand that the basic rule of thumb is to avoid layering oil based paint over latex paint. However, I just painted Killz restoration interior primer over old paint in a failed attempt to lock the tar/nicotine tar from bleeding through. So my question is very specific. Since Kilz Restoration Primer is uniquely different from other latex primers (acts like a shellac type paint), can I layer Kilz oil based primer over Kilz Restoration Interior Primer?
Kilz Restoration primer, formerly Kilz Max, is a water-based product that can be top coated with oil-based and latex paint. My concern is how well the Kilz Restoration, or the layer underneath that, is bonding with the surface. If the latex primer's scratching off easily with your fingernail, or rubbing off, I would strip it off and prime with oil primer. If the only issue is the bleed-through, priming with oil-based primer will stop the nicotine bleed-through and work fine over the latex underneath.
