Best way to prep stained trim work for painting

I a have a LOT of trim that is stained and sealed with poly. We want to paint it white now. What is the easiest way to prep this before painting?

I have been told light sanding OR abrasive pad OR liquid sander etc. The trim has a fair amount of intricate contouring. Also, how do you do inside corners best?

Thanks for any tips!

It the poly glossy?

You need to scuff it up to a dull finish, the scotch brite pads will work good!

A coat of primer, then paint and you should be good!

Not sure what your asking about for inside corners!

Thanks Marq1. I was just concerned about really getting into the corners to scuff them up.

Light scuff sanding then an oil based primer.

I normally scuff sand, wipe down with a liquid deglosser and then apply a solvent based primer [oil or pigmented shellac] Expect to apply 1 coat primer and 2 coats finish. After the primer has dried and been sanded you should caulk all the joints.
