I know this have been covered before but I couldn't find it on the forums.  Does it matter what type of paint you apply over a coat of shellac?

Hi Randall, just be sure to scuff the shellac first to give the paint something to hold to and wipe off any sanding dust. As far as paint, I have used latex with no issue. I am not sure how oil base would work. Ifnothing else, try it on a small part and see if it curls or beads up.

I agree with Bob, scuff and paint.

The oil base should not be an issue, shellac is alcohol based when applied, the oil should not re-activate the shellac. But it is always wise to test before you proceed as Bob mentioned. Great to see you around these parts again Randall!!

I would sand what ever it is to be painted to rough up the shellac. Then I would apply primer to the surface. Give it good time to dry and then paint over the primer. The primer will shield the shellac from reacting with the top coats and can be lightly sanded for a great smooth finish. Normally something like 400 or higher. Alway try and use a test piece, that assures if you are going to have any reaction between material being applied.
