Touching Up The Primer - Without Leaving Marks?


One room which was skim coated, the workers didn't sand it too good and there were also some defects that needed fixing...I noticed this after priming.

I went back and compounded some places on walls and ceiling to smooth out some screening marks and also small voids and defects. So there's a bunch of small patches of compound a few inches in diameter...but there's also a several areas with at least a foot diameter - or even two feet - of compound touch up. These newly compounded areas have all been sanded and blended.

What is the recommended method of dealing with these post-priming patches? Should they be primed or is it OK just painting the top coat* over them? My gut tells me they need primer, but I do not want to leave roller or brush marks which might telegraph through the topcoat, especially brush marks. So, I'm thinking spot rolling these areas with a pretty dry roller (Ben Moore Fresh Start primer) will blend the new primer in leaving minimal marks. Does that work, or is it necessary to re-prime the entire room.

Is there a better way?

*Ceiling paint will be Ben Moore Moresco and wall paint will be Ben Moore Regal, Flat or Matte.

your approach is correct. The newly patched areas need to be primed. If you rolled the primer, roll the patches. If you do not prime again these areas will "flash" and you will see them as a different sheen. You do not need to prime the entire wall but you need to be sure not to miss any areas you touched up. What I do is mark these areas that need or get patched with a circle in pencil lightly. The primer does not cover these marks but the top coat will.

Thanks for the insight Bob, much appreciated.

...and marking with a pencil will make this a sane process.

I agree. With that much patch work you really want to use primer. Rolling is better for patching as it starts to build up the texture (Orange peel) to match the existing wall. Just make sure smooth out the edges of the primed areas or they will show through the top coat.

Quick question: is there an easy way to sand joint compound that has been applied over primer, so as to blend the compound patch seamlessly into the wall?
Some primer doesn't like to be sanded.

No. touch up after priming is always done. After priming the light will show differently and new areas to touch up will be found. You could use a scraper to flatten the bad joint and remove the primer coat but why? Just put some compound let it dry sand and re-prime.
