I made an oak chest & lined it with cedar. After finishing the underside of the lid I read that the oil in cedar will soften the poly. Is that true? If yes can I use shellac to seal the poly in?

I’ve never heard of it softening poly. I know it’s not recommended on exterior cedar that is subject to the elements – but that is because it will degrade and become brittle under UV… not because of the wood.


PS: I have a few things I’ve made out of cedar and finished with oil based poly… some are a few years old and no problems yet ;)

Doesn’t a finish on the cedar defeat the purpose of using cedar on the interior?

I am not going to finish the cedar lining I only am concerned about the under side of the oak top which I already put the poly on. I’ve been told shellac over the poly will seal it. Will that work? Any more suggestions? Thanks for your comments.
