Was spot painting another area of my house yesterday... *I'd taken down
a big mirror (permanently mounted) over my fireplace and cleaned up the
marks around it, patched the plaster around the boxes for the wall
sconces, etc. *I started by shaving down the brush marks with a razor
blade and/or painter's scraper, then sanded with 80 grit, then 120 grit,
patched some holes with patching plaster, went over everything again
with 120, primed with Kilz 2, then finally finished with two coats of
Benjamin Moore flat. *(all paint was applied with a 3/8" nap roller,
save for cutting in around the mantel, ceiling, and window trim.)

Here's the weirdness. *I remember after painting, stepping back and
noticing that there was a really noticeable spot at the upper left hand
corner of where the mirror was where there was a lot of the texture of
the old brush strokes from where the old paint had been cut in around
the mirror. *I distinctly remember mentioning this and making some
comment about how I thought I'd done a better job prepping than that.
Went back today to remount the sconces and now it's barely noticeable -
if I hadn't known exactly what to look for and where I would never have
seen anything. *Basically, what you'd expect from a halfway decent prep
job.

The only explanation I can think of for this is that the Kilz reacted
somehow with either some patching plaster or the old paint and bubbled
up, and then when everything dried it shrank back down to the wall.
Sound plausible? *Should I make a mental note to sand that area back
down when I finally repaint the whole room, or not worth worrying about?

Change in appearance of old brush strokes is probably just different
lighting....might show more when there is cross lighting than when there
is direct lighting. *Didn't rush all those steps, I hope? *Sounds like a
lot to do in one day.- Hide quoted text -

Could it have been a difference in drying time due to a cool area that
slowed drying in the one spot? I have seen this more than once in 50
years of painting various owned homes in the winter time.
