tips for painting over new drywall mud

[lust2hart]

We needed to cut into our walls for a reno project and had a company out to repair, and the blending required about half the wall to be covered in mud. Do you all have any tips for painting over this to help it blend in with the rest of the wall, texture-wise? My walls aren't textured-textured, just the regular eggshellish texture that comes with a paint roller, but when I've just regularly painted over smaller mud jobs there is a definite difference. 

Also, do you think I need to use a separate primer? The drywall guy suggested this because the mud will soak up so much and his thought was, why waste paint on that, but I have a bunch of this color that I will never use up so I don't really care about that - but thought a separate primer might help with the texturing (I really don't know, just spitballing here?!)?

primer is a must. paint that says you don't have to prime is lying to you. Also make sure to sand the repaired area and the surrounding area well. If you can, repaint the whole wall so that it matches really well.

Yes, you definitely need to prime before you paint -- separate product, separate application.  It's not really for "texture" but because the unprimed surface will absorb excessive amounts of paint, and the sheen/color won't be uniform if you don't prime over the mud first.

I've never had a problem with texture after a wall repair.  I sand, prime, and paint with good quality, thick paint like BM or SW's Duration/Emerald lines, and it comes out evenly.

The mud will need to be sanded really well so it doesn’t show as a different texture. Then you do need to prime, and I would expect to re-paint the whole wall to achieve an even look.

Thanks all. I was already planning to repaint the whole wall; should I prime the whole wall too?

It would be best to.
