Need to recoat cedar

Submitted to Product Chat


Wondered our contractor installed new cedar trim molding 9 years ago and chose to seal it with amber shellac. Nice warm tone slightly tinted to enhance wood grain.

However, over the years it looks like it needs a freshening up.
It looks dry and incomplete.
Our cedar log walls were refinished by a paint contractor 7 years ago and used a water-based poly and that’s holding up looking much better.
Expect likely its the polys satin sheen.

I wondered can these shellac moldings be recovered with a water-based poly without any particular attention or prep ….compatibility wise…...with desiring an over application using two different products?
Can anything go over this older shellac application that might present a better seal and more compatible matching sheen?

Thanks for your time and trouble to help me consider the proper approach!
