some new and some old wall -- how to prime?
We took out an old door frame and made an eyebrow opening -- which is new textured paint. We now have a combination of the new textured paint, with the old painted textured walls -- the new areas are feathered to make the whole thing seamless -- we hope. There are a few areas where we added some textured paint on to the old walls to try to get a consistent texture throughout.
Should we prime just the new areas or prime everything before painting?
