Greenboard and Drywall Prep.

I have helped mud, sand, etc. drywall in the past BUT do not know rights and wrongs of drywall that has been left unfinished for years in an otherwise used bathroom. I want to finish remodeling children's bathroom. Drywall has patches of mud that need sanding and the same with the greenboard in ceilling of shower. Tub has been used without the shower fixture so ceiling has not got wet.

Do I need any further preparation on the shower ceiling greenboard that looks unmarred or drywall above sink area that does look like water spots (or could be soap, toothpaste water splats) but has not rot or mildew?

Thank you,
from a (new to this) fixer upper mom

Welcome to the forums!

It wouldn't hurt to give everything a scuff sanding, including the areas without joint compound. Other than that it should be good to go. If there are any water stains, they will need a coat of an oil base primer to seal them. Also oil base primer will adhere better to any "iffy" areas like soap/hair spray residue.
