We are preparing to prime interior walls using a shellac-based primer, followed with a setting compound mud. Will the mud stick adequately to the shellac-based product or do we need to use another type of primer over the shellac primer?

Why would you prime prior to mudding? – DA01 May 29 '12 at 17:05

Because there was a long history of smoking in this house and we want to permanently 'bury' any odor. Our understanding is that shellac primer is the only one that will achieve this goal. – RET May 30 '12 at 14:09
   
So is this existing sheetrock? If so, what are you mudding on the exiting sheetrock? – DA01 May 30 '12 at 14:12

The walls are currently painted, and have lath and plaster. Our end goal is to 'bury' any odors with the shellac, then mud (skim-coat) over the walls to create a different texture to the walls. – RET May 30 '12 at 14:38
If the walls are already painted, that's an issue right there. You'd likely going to have to go with a quality primer first. Something that will allow the mud to nicely bond--but even then, you're somewhat at the mercy of the existing layers of paint bonding well. So, prime, skim coat, THEN shellac. (Actually, if you go with a really good primer, you might not even need the shellac). – DA01 May 30 '12 at 16:06

Yes. This fine plastering expert actually recommends it: http://www.bristegroup.com/index.php?option=com_content&task=view&id=45&Itemid=82

If the surface is new, eliminate any possibility of coating failure by priming the surface in an oil primer, B-I-N SHELLAC BASE is preferred.

Here is another expert plasterer doing the same: http://www.fauxforum.com/viewtopic.php?t=6915

I am attempting an identical project (nicotine stained walls and shellac). My email is on my profile if you would like to discuss your experience. – skybreaker May 31 '12 at 1:45
